How light can shift your mood and mental health

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/jacob-crouse-981668">Jacob Crouse</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/emiliana-tonini-1638957">Emiliana Tonini</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>, and <a href="https://theconversation.com/profiles/ian-hickie-961">Ian Hickie</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> It’s spring and you’ve probably noticed a change in when the Sun rises and sets. But have you also noticed a change in your mood? We’ve known for a while that light plays a role in our wellbeing. Many of us tend to feel more positive when <a href="https://pubmed.ncbi.nlm.nih.gov/32925966/">spring returns</a>. But for others, big changes in light, such as at the start of spring, can be tough. And for many, bright light at night can be a problem. Here’s what’s going on. <h2>An ancient rhythm of light and mood</h2> In an <a href="https://theconversation.com/how-light-tells-you-when-to-sleep-focus-and-poo-236780">earlier article</a> in our series, we learned that light shining on the back of the eye sends “<a href="https://pubmed.ncbi.nlm.nih.gov/25451984/">timing signals</a>” to the brain and the master clock of the circadian system. This clock coordinates our daily (circadian) rhythms. “Clock genes” also regulate circadian rhythms. These genes control the timing of when many other genes <a href="https://pubmed.ncbi.nlm.nih.gov/31557726/">turn on and off</a> during the 24-hour, light-dark cycle. But how is this all linked with our mood and mental health? Circadian rhythms can be disrupted. This can happen if there are problems with how the body clock develops or functions, or if someone is routinely exposed to bright light at night. When circadian disruption happens, it increases the risk of certain <a href="https://pubmed.ncbi.nlm.nih.gov/33689801/">mental disorders</a>. These include <a href="https://www.sciencedirect.com/science/article/abs/pii/S0149763422000744">bipolar disorder</a> and <a href="https://bmcmedicine.biomedcentral.com/articles/10.1186/1741-7015-11-79">atypical depression</a> (a type of depression when someone is extra sleepy and has problems with their energy and metabolism). <h2>Light on the brain</h2> Light may also affect circuits <a href="https://pubmed.ncbi.nlm.nih.gov/35687680/">in the brain</a> that control mood, as <a href="https://pubmed.ncbi.nlm.nih.gov/23151476/">animal studies show</a>. There’s evidence this happens in humans. A brain-imaging study showed exposure to bright light in the daytime while inside the scanner <a href="https://www.cell.com/fulltext/S0960-9822(06)01758-1">changed the activity</a> of a brain region involved in mood and alertness. Another brain-imaging study <a href="https://pubmed.ncbi.nlm.nih.gov/22111663/">found</a> a link between daily exposure to sunlight and how the neurotransmitter (or chemical messenger) serotonin binds to receptors in the brain. We see alterations in serotonin binding in several <a href="https://pubmed.ncbi.nlm.nih.gov/33651238/">mental disorders</a>, including depression. <h2>What happens when the seasons change?</h2> Light can also affect mood and mental health as the seasons change. During autumn and winter, symptoms such as low mood and fatigue can develop. But often, once spring and summer come round, these symptoms go away. This is called “seasonality” or, when severe, “<a href="https://www.aafp.org/pubs/afp/issues/2020/1201/p668.html">seasonal affective disorder</a>”. What is less well known is that for other people, the change to spring and summer (when there is more light) can also come with a change in mood and mental health. Some people experience increases in energy and the drive to be active. This is positive for some but can be seriously destabilising for others. This too is an example of seasonality. Most people <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0239033">aren’t very seasonal</a>. But for those who are, seasonality has a <a href="https://pubmed.ncbi.nlm.nih.gov/8540777/">genetic component</a>. Relatives of people with seasonal affective disorder are more likely to also experience seasonality. Seasonality is also more common in conditions such as <a href="https://pubmed.ncbi.nlm.nih.gov/25063960/">bipolar disorder</a>. For many people with such conditions, the shift into shorter day-lengths during winter can trigger a depressive episode. Counterintuitively, the longer day-lengths in spring and summer can also destabilise people with bipolar disorder into an “<a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10947388/">activated</a>” state where energy and activity are in overdrive, and symptoms are harder to manage. So, seasonality can be serious. Alexis Hutcheon, who experiences seasonality and helped write this article, told us: <blockquote> […] the season change is like preparing for battle – I never know what’s coming, and I rarely come out unscathed. I’ve experienced both hypomanic and depressive episodes triggered by the season change, but regardless of whether I’m on the ‘up’ or the ‘down’, the one constant is that I can’t sleep. To manage, I try to stick to a strict routine, tweak medication, maximise my exposure to light, and always stay tuned in to those subtle shifts in mood. It’s a time of heightened awareness and trying to stay one step ahead. </blockquote> <h2>So what’s going on in the brain?</h2> One explanation for what’s going on in the brain when mental health fluctuates with the change in seasons relates to the neurotransmitters serotonin and dopamine. Serotonin helps regulate mood and is the target of <a href="https://journals.sagepub.com/doi/full/10.1177/0706743716659417">many</a> <a href="https://pubmed.ncbi.nlm.nih.gov/38185236/">antidepressants</a>. There is some evidence of seasonal changes in serotonin levels, potentially being lower <a href="https://academic.oup.com/brain/article/139/5/1605/2468755?login=false">in</a> <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(02)11737-5/abstract?cc=y%3D">winter</a>. Dopamine is a neurotransmitter involved in reward, motivation and movement, and is also a target of some <a href="https://journals.sagepub.com/doi/full/10.1177/0706743716659417">antidepressants</a>. Levels of dopamine may also change with the <a href="https://www.nature.com/articles/s41398-023-02365-x">seasons</a>. But the neuroscience of seasonality is a developing area and more research <a href="https://www.nature.com/articles/s41398-023-02365-x">is needed</a> to know what’s going on in the brain. <h2>How about bright light at night?</h2> We know exposure to bright light at night (for instance, if someone is up all night) can disturb someone’s circadian rhythms. This type of circadian rhythm disturbance is associated with higher rates of symptoms <a href="https://www.nature.com/articles/s44220-023-00135-8">including</a> self-harm, depressive and anxiety symptoms, and lower wellbeing. It is also associated with higher rates of <a href="https://pubmed.ncbi.nlm.nih.gov/32639562/">mental disorders</a>, such as major depression, bipolar disorder, psychotic disorders and post-traumatic stress disorder (or PTSD). Why is this? Bright light at night confuses and destabilises the body clock. It disrupts the rhythmic regulation of mood, cognition, appetite, metabolism and <a href="https://pubmed.ncbi.nlm.nih.gov/38214638/">many</a> <a href="https://pubmed.ncbi.nlm.nih.gov/34419186/">other</a> <a href="https://pubmed.ncbi.nlm.nih.gov/33689801/">mental</a> <a href="https://pubmed.ncbi.nlm.nih.gov/36661342/">processes</a>. But people differ hugely in their <a href="https://www.pnas.org/doi/10.1073/pnas.1901824116">sensitivity to light</a>. While still a hypothesis, people who are most sensitive to light may be the most vulnerable to body clock disturbances caused by bright light at night, which then leads to a higher risk of mental health problems. <h2>Where to from here?</h2> Learning about light will help people better manage their mental health conditions. By encouraging people to better align their lives to the light-dark cycle (to stabilise their body clock) we may also help prevent conditions such as <a href="https://pubmed.ncbi.nlm.nih.gov/34419186/">depression</a> and <a href="https://www.sciencedirect.com/science/article/pii/S0149763422000744">bipolar disorder</a> emerging in the first place. Healthy light behaviours – avoiding light at night and seeking light during the day – are good for everyone. But they might be especially helpful for people <a href="https://www.sciencedirect.com/science/article/pii/S0149763422000744">at risk</a> of mental health problems. These include people with a family history of mental health problems or people who are <a href="https://pubmed.ncbi.nlm.nih.gov/38185236/">night owls</a> (late sleepers and late risers), who are more at risk of body clock disturbances. <hr /> Alexis Hutcheon has lived experience of a mental health condition and helped write this article.

What washing machine settings can I use to make my clothes last longer?

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/alessandra-sutti-1513345">Alessandra Sutti</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>; <a href="https://theconversation.com/profiles/amol-patil-1513347">Amol Patil</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>, and <a href="https://theconversation.com/profiles/maryam-naebe-1513346">Maryam Naebe</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> Orbiting 400 kilometres above Earth’s surface, the astronauts on the International Space Station live a pretty normal social life, if not for one thing: they happily wear their unwashed clothes <a href="https://www.nasa.gov/centers-and-facilities/glenn/nasa-glenn-interns-take-space-washing-machine-designs-for-a-spin/">for days and weeks at a time</a>. They can’t do their laundry <a href="https://www.esa.int/Enabling_Support/Space_Engineering_Technology/Keeping_your_underwear_clean_on_the_Moon">just yet</a> because water is scarce up there. But down here on Earth, washing clothes is a large part of our lives. <a href="https://bigee.net/media/filer_public/2013/03/28/bigee_domestic_washing_machines_worldwide_potential_20130328.pdf">It’s estimated</a> that a volume of water equivalent to 21,000 Olympic swimming pools is used every day for domestic laundry worldwide. Fibres from our clothes make their way into the environment via the air (during use or in the dryer), water (washing) and soil (lint rubbish in landfill). Most of this fibre loss is invisible – we often only notice our favourite clothing is “disappearing” when it’s too late. How can you ensure your favourite outfit will outlast your wish to wear it? Simple question, complex answer. <h2>Washing machines are not gentle</h2> When you clean the filters in your washing machine and dryer, how often do you stop to think that the lint you’re holding <a href="https://theconversation.com/uk-laundry-releases-microfibres-weighing-the-equivalent-of-1-500-buses-each-year-199712">was, in fact, your clothes</a>? Laundering is harsh on our clothes, and <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0250346">research confirms this</a>. Several factors play a role: the type of washing machine, the washing cycle, detergents, temperature, time, and the type of fabric and yarn construction. There are two types of domestic washing machines: top-loader and front-loader. Mechanical agitation (the way the machine moves the clothes around) is one of the things that helps ease dirt off the fabric. Top-loaders have a vertical, bucket-like basket with a paddle, which sloshes clothes around in a large volume of water. Front-loaders have a horizontal bucket which rotates, exposing the clothes to a smaller volume of water – it takes advantage of gravity, not paddles. Top-loading machines <a href="https://link.springer.com/article/10.1007/s12541-010-0047-7">tend to be more aggressive</a> towards fabrics than front-loaders due to the different mechanical action and larger volumes of water. Washing machine panels also present many choices. Shorter, low-temperature programs <a href="https://clevercare.info/more-eco-temperature-tips">are usually sufficient for everyday stains</a>. Choose longer or <a href="https://iprefer30.eu/animations/UK/wash-brochure-uk.pdf">high-temperature programs</a> only for clothing you have concerns about (healthcare uniforms, washable nappies, etc.). Generally, washing machine programs are carefully selected combinations of water volume, agitation intensity and temperature recommended by the manufacturer. They take into consideration the type of fabric and its level of cleanliness. Select the wrong program and you can say goodbye to your favourite top. For example, high temperatures or harsh agitation may cause some fibres to weaken and break, causing holes in the garment. <h2>Some fabrics lose fibres more easily than others</h2> At a microscopic level, the fabric in our clothes is made of yarns – individual fibres twisted together. The nature and length of the fibres, the way they are twisted and the way the yarns form the fabric can determine how many fibres will be lost during a wash. In general, if you want to lose fewer fibres, you should wash less frequently, but some fabrics are affected more than others. Open fabric structures (knits) with loose yarns <a href="https://www.nature.com/articles/s41598-021-98836-6">can lose more fibres</a> than tighter ones. Some sports clothing, like running shirts, are made of continuous filament yarn. These fibres are less likely to come loose in the wash. Cotton fibres are only a few centimetres long. Twisted tightly together into a yarn, they can still escape. Wool fibres are also short, but have an additional feature: scales, which make wool clothes much more delicate. Wool fibres can come loose like cotton ones, but also tangle with each other during the wash due to their scales. This last aspect is what causes wool garments to shrink when <a href="https://journals.sagepub.com/doi/abs/10.1177/004051756403400303">exposed to heat</a> and agitation. <h2>Go easy on the chemicals</h2> The type of detergent and other products you use also makes a difference. Detergents contain a soap component, enzymes to make stains easier to remove at low temperature, and fragrances. Some contain harsher compounds, such as bleaching or whitening agents. Modern detergents are very effective at <a href="https://www.choice.com.au/home-and-living/laundry-and-cleaning/laundry-detergents/review-and-compare/laundry-detergents">removing stains such as food</a>, and you don’t need to use much. An incorrect choice of wash cycles, laundry detergent and bleaching additives could cause disaster. Certain products, like bleach, can <a href="https://site.extension.uga.edu/textiles/textile-basics/understand-your-fibers/">damage some fibres like wool and silk</a>. Meanwhile, research on <a href="https://www.sciencedirect.com/science/article/pii/S0269749120366872?via%3Dihub">fabric softeners and other treatments</a> <a href="https://journals.plos.org/plosone/article/file?id=10.1371/journal.pone.0233332&type=printable">continues</a> – there’s no one-size-fits-all answer about their potential impact on our clothes. <h2>Just skip laundry day</h2> So, how to ensure your clothes last longer? The main tip is to wash them less often. When it’s time for a wash, carefully read and follow the care labels. In the future, our washing machines will <a href="https://www.teknoscienze.com/tks_article/trends-in-laundry-by-2030/">recognise fabrics and select the wash cycle</a>. For now, that’s our responsibility. And the next time you throw your shirt into the dirty laundry basket, stop. Think of the astronauts orbiting above Earth and ask yourself: if they can go without clean laundry for a few days, maybe I can too? (Although we don’t recommend just burning your dirty undies, either.)<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/224064/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <figure><iframe src="https://www.youtube.com/embed/C1j6KLP492E?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <a href="https://theconversation.com/profiles/alessandra-sutti-1513345">Alessandra Sutti</a>, Associate Professor, Institute for Frontier Materials, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>; <a href="https://theconversation.com/profiles/amol-patil-1513347">Amol Patil</a>, Research Engineer, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>, and <a href="https://theconversation.com/profiles/maryam-naebe-1513346">Maryam Naebe</a>, Associate professor, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

For type 2 diabetes, focusing on when you eat – not what – can help control blood sugar

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/evelyn-parr-441878">Evelyn Parr</a>, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a> and <a href="https://theconversation.com/profiles/brooke-devlin-2237174">Brooke Devlin</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> Type 2 diabetes affects <a href="https://www.aihw.gov.au/reports/diabetes/diabetes/contents/how-common-is-diabetes/type-2-diabetes">1.2 million Australians</a> and accounts for <a href="https://www.diabetesaustralia.com.au/about-diabetes/type-2-diabetes/">85-90%</a> of all diabetes cases. This chronic condition is characterised by high blood glucose (sugar) levels, which carry serious <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(17)30058-2/abstract">health</a> risks. <a href="https://www.nature.com/articles/nrendo.2017.151">Complications</a> include heart disease, kidney failure and vision problems. Diet is an important way people living with type 2 diabetes manage blood glucose, alongside exercise and medication. But while we know individualised, professional dietary advice improves blood glucose, it can be <a href="https://linkinghub.elsevier.com/retrieve/pii/S0168822717317588">complex</a> and is not always <a href="https://www.publish.csiro.au/py/PY13021">accessible</a>. <a href="https://www.sciencedirect.com/science/article/pii/S0168822724008039">Our new study</a> looked at the impact of time-restricted eating – focusing on when you eat, rather than what or how much – on blood glucose levels. We found it had similar results to individualised advice from an accredited practising dietitian. But there were added benefits, because it was simple, achievable, easy to stick to – and motivated people to make other positive changes. <h2>What is time-restricted eating?</h2> Time-restricted eating, also known as <a href="https://www.annualreviews.org/content/journals/10.1146/annurev-nutr-082018-124320">the 16:8 diet</a>, became popular for weight loss around 2015. Studies have since shown it is also an <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2811116">effective way</a> for people with type 2 diabetes to manage blood glucose. Time-restricted eating involves limiting when you eat each day, rather than focusing on what you eat. You restrict eating to a window during daylight hours, for example between 11am and 7pm, and then fast for the remaining hours. This can sometimes naturally lead to also eating less. Giving your body a break from constantly digesting food in this way helps align eating with natural <a href="https://doi.org/10.1111/jne.12886">circadian rhythms</a>. This <a href="https://doi.org/10.1111/jnc.15246">can help</a> regulate metabolism and improve overall health. For people with type 2 diabetes, there may be specific benefits. They often have their <a href="https://doi.org/10.2337/dc12-2127">highest blood glucose</a> reading in the morning. Delaying breakfast to mid-morning means there is time for physical activity to occur to help reduce glucose levels and prepare the body for the first meal. <h2>How we got here</h2> We ran an <a href="https://www.mdpi.com/2072-6643/12/11/3228">initial study</a> in 2018 to see whether following time-restricted eating was achievable for people with type 2 diabetes. We found participants could easily stick to this eating pattern over four weeks, for an average of five days a week. Importantly, they also had improvements in blood glucose, spending less time with high levels. <a href="https://www.mdpi.com/2072-6643/12/2/505">Our previous research</a> suggests the reduced time between meals may play a role in how the hormone insulin is able to reduce glucose concentrations. <a href="https://doi.org/10.1001/jamanetworkopen.2023.39337">Other studies</a> have confirmed these findings, which have <a href="https://doi.org/10.1186/s12986-021-00613-9">also shown</a> notable improvements in HbA1c. This is a <a href="https://www.ncbi.nlm.nih.gov/books/NBK304271/">marker</a> in the blood that represents concentrations of blood glucose over an average of three months. It is the <a href="https://journals.sagepub.com/doi/10.4137/BMI.S38440">primary clinical tool</a> used for diabetes. However, these studies provided intensive support to participants through weekly or fortnightly meetings with researchers. While we know this level of support <a href="https://www.nature.com/articles/0802295">increases</a> how likely people are to stick to the plan and improves outcomes, it is not readily available to everyday Australians living with type 2 diabetes. <h2>What we did</h2> In our <a href="https://www.sciencedirect.com/science/article/pii/S0168822724008039">new study</a>, we compared time-restricted eating directly with advice from an <a href="https://dietitiansaustralia.org.au/working-dietetics/standards-and-scope/role-accredited-practising-dietitian">accredited practising dietitian</a>, to test whether results were similar across six months. We recruited 52 people with type 2 diabetes who were currently managing their diabetes with up to two oral medications. There were 22 women and 30 men, aged between 35 and 65. Participants were randomly divided into two groups: diet and time-restricted eating. In both groups, participants received four consultations across the first four months. During the next two months they managed diet alone, without consultation, and we continued to measure the impact on blood glucose. In the diet group, consultations focused on changing their diet to control blood glucose, including improving diet quality (for example, eating more vegetables and limiting alcohol). In the time-restricted eating group, advice focused on how to limit eating to a nine-hour window between 10am and 7pm. Over six months, we measured each participant’s blood glucose levels every two months using the HbA1c test. Each fortnight, we also asked participants about their experience of making dietary changes (to what or when they ate). <h2>What we found</h2> We found time-restricted eating was as effective as the diet intervention. Both groups had reduced blood glucose levels, with the greatest improvements occurring after the first two months. Although it wasn’t an objective of the study, some participants in each group also lost weight (5-10kg). When surveyed, participants in the time-restricted eating group said they had adjusted well and were able to follow the restricted eating window. Many told us they had family support and enjoyed earlier mealtimes together. Some also found they slept better. After two months, people in the time-restricted group were looking for more dietary advice to further improve their health. Those in the diet group were less likely to stick to their plan. Despite similar health outcomes, time-restricted eating seems to be a simpler initial approach than making complex dietary changes. <h2>Is time-restricted eating achievable?</h2> The main barriers to following time-restricted eating are social occasions, caring for others and work schedules. These factors may prevent people eating within the window. However, there are many benefits. The message is simple, focusing on when to eat as the main diet change. This may make time-restricted eating more translatable to people from a wider variety of socio-cultural backgrounds, as the types of foods they eat don’t need to change, just the timing. Many people don’t have access to more individualised support from a dietitian, and receive nutrition advice from their GP. This makes time-restricted eating an alternative – and equally effective – strategy for people with type 2 diabetes. People should still try to stick to <a href="https://www.eatforhealth.gov.au/guidelines/guidelines">dietary guidelines</a> and prioritise vegetables, fruit, wholegrains, lean meat and healthy fats. But our study showed time-restricted eating may also serve as stepping stone for people with type 2 diabetes to take control of their health, as people became more interested in making diet and other positive changes. Time-restricted eating might not be appropriate for everyone, especially people on medications which don’t recommend fasting. Before trying this dietary change, it’s best speak to the healthcare professional who helps you manage diabetes.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/241472/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/evelyn-parr-441878">Evelyn Parr</a>, Research Fellow in Exercise Metabolism and Nutrition, Mary MacKillop Institute for Health Research, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a> and <a href="https://theconversation.com/profiles/brooke-devlin-2237174">Brooke Devlin</a>, Lecturer in Nutrition and Dietetics, School of Human Movement and Nutrition Sciences, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Music and dementia: researchers are still making discoveries about how songs can help sufferers

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/rebecca-atkinson-1288605">Rebecca Atkinson</a>, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a> and <a href="https://theconversation.com/profiles/ming-hung-hsu-2215063">Ming-Hung Hsu</a>, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a> Music is woven into the fabric of our everyday lives. Whether it’s lifting our spirits, pushing us to run faster or soothing us to sleep, we can all <a href="https://www.frontiersin.org/journals/psychology/articles/10.3389/fpsyg.2021.713818/full">recognise its power</a>. So it’s no wonder it is increasingly being used in medical treatment. As well as proving very useful in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3863265/">cancer treatment</a>, managing <a href="https://www.sciencedirect.com/science/article/pii/S1526590022000153">chronic pain</a> and even helping the brain <a href="https://www.frontiersin.org/articles/10.3389/fnhum.2014.00245/full">recover after a stroke</a>, researchers have also been making great strides in using music to help patients with dementia. It reduces patients’ <a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD003477/full">anxiety and depression</a>, and <a href="https://www.thelancet.com/journals/eclinm/article/PIIS2589-5370(23)00401-7/fulltext">improves wellbeing</a> both for them and their carers <a href="https://www.cambridge.org/core/journals/the-british-journal-of-psychiatry/article/individual-music-therapy-for-depression-randomised-controlled-trial/A1CD72904929CECCB956F4F3B09605AF">by enhancing</a> everyone’s ability to adapt and cope with adversity or stress. <a href="https://www.bamt.org">Music therapy</a> in the form of playing, singing or listening to music can also have a <a href="https://journals.sagepub.com/doi/abs/10.1177/1362361309105660">positive effect</a> on cognitive function – particularly for <a href="https://link.springer.com/article/10.1186/1472-6882-10-39">older adults</a> either with dementia or memory issues. So why does music appear to have such a powerful effect for people with dementia? <h2>Music and the brain</h2> About a decade ago, <a href="https://www.sciencedirect.com/science/article/abs/pii/S1053811911013000">researchers discovered that</a> when people listened to music, multiple areas of the brain were involved in processing it. These included the limbic (which processes emotions and memory), cognitive (involved with perception, learning and reaction) and motor areas (responsible for voluntary movement). This challenged preconceptions that music was processed more narrowly in the brain – and helped explain why it has such a unique neurological impact. Not only that, research has shown that music might help <a href="https://www.sciencedirect.com/science/article/abs/pii/S0306987708002880">regenerate the brain</a> and its connections. Many <a href="https://www.nhs.uk/conditions/dementia/about-dementia/causes/">causes of dementia</a> centre around cell death in the brain, raising the possibility that music could help people with dementia by mending or strengthening damaged neural connections and cells. It’s not just any music that has a regenerative effect on the brain, though. <a href="https://www.frontiersin.org/articles/10.3389/fnhum.2016.00103/full">Familiar and favourite music</a> has been shown to have the biggest impact on the way we feel, and is closely linked with memory and emotions. This is because listening to our favourite songs <a href="https://www.nature.com/articles/nn.2726">releases feel-good hormones</a> that give us a sense of pleasure. Curated music playlists of favourite music could be the key in helping us deal with the <a href="https://journals.sagepub.com/doi/full/10.1177/10298649211030318">stress of everyday life</a>. This is relevant to Alzheimer’s and other forms of dementia because researchers have discovered that parts of the brain linked with <a href="https://academic.oup.com/brain/article/138/8/2438/330016">musical memories</a> are less affected by these conditions than other areas of the brain. This explains why memories and experiences that are linked to <a href="https://link.springer.com/article/10.14283/jpad.2018.19">favourite music</a> are often preserved for people with such conditions. Listening to music can also <a href="https://pubmed.ncbi.nlm.nih.gov/34346261/">help manage</a> their experiences of distress, agitation and “<a href="https://www.alzheimers.org.uk/about-dementia/symptoms-and-diagnosis/symptoms/sundowning">sundowning</a>” – where a person is more confused in the afternoon and evening. In a <a href="https://www.sciencedirect.com/science/article/pii/S0197457224002209?utm_campaign=STMJ_219742_AUTH_SERV_PA&utm_medium=email&utm_acid=224973760&SIS_ID=&dgcid=STMJ_219742_AUTH_SERV_PA&CMX_ID=&utm_in=DM500444&utm_source=AC_">small study</a> conducted by us and our colleagues at the Cambridge Institute for Music Therapy Research, we showed just how great of an effect listening to music can have for people with dementia. We found that when people with dementia repeatedly listened to their favourite music, their heart rate and movements changed in direct response. This showed that people’s physical responses were affected by musical features like rhythm and arrangement. Their heart rate also changed when they sang along to music, or when they began reminiscing about old memories or stories while listening to a song or thinking about the music. These changes are important because they show how music affects movement, emotions and memory recall. Studies have also shown that during and after listening to music, people with dementia <a href="https://www.mdpi.com/2076-3425/13/7/1103">experienced less agitation</a>, aggression and anxiety, and their general mood was improved. They even needed less medication when they had regular music sessions. Other researchers have even begun testing the effects of <a href="https://onlinelibrary.wiley.com/doi/abs/10.1002/gps.4721?casa_token=VufeKQP7aNsAAAAA%3AMSOgiwUQYKqmmrLsUFv9glmSnc5BMxoqeMmmt3HX4BJX2Fs2UKeXjnN2850o1Umz0j1NvmrpQ3W3Pw">music training programmes</a> to support cognition for people with dementia. Results have been promising so far – with adults in the study showing improved executive functioning (problem solving, emotion regulation and attention) compared to those who took part in just physical exercise. So, music is likely to continue to be a useful medical treatment for people with dementia. But based on what we know so far, it’s important that it comes from the patient’s own music collection – and is used alongside other management techniques such as using drugs that can slow the progression of dementia or help manage symptoms to support self-care and wellbeing.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/239446/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/rebecca-atkinson-1288605">Rebecca Atkinson</a>, Researcher in Music Therapy, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a> and <a href="https://theconversation.com/profiles/ming-hung-hsu-2215063">Ming-Hung Hsu</a>, Senior Research Fellow, Music Therapy, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

We know parents shape their children’s reading – but so can aunts, uncles and grandparents, by sharing beloved books

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/emily-grace-baulch-1399683">Emily Grace Baulch</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> <a href="https://creative.gov.au/news/media-releases/revealing-reading-a-survey-of-australian-reading-habits/">Over 80%</a> of Australians with children encourage them to read. Children whose parents enjoy reading are <a href="https://www.booktrust.org.uk/news-and-features/news/news-2023/new-research-from-booktrust-reveals-the-impact-of-parental-reading-enjoyment-on-childrens-reading-habits/">20% more likely</a> to enjoy it too. My research has found parents aren’t the only family members who play an important role in developing a passion for reading – extended family, from grandparents to siblings, uncles and great-aunts, also influence readers’ connections to books. I surveyed 160 Australian readers about their home bookshelves and reading habits. More than 80% of them acknowledged the significant influence of family in what and how they read. Reading to children is often <a href="https://www.booktrust.org.uk/globalassets/resources/research/booktrust-family-survey-research-briefing-2-reading-influencers.pdf">the invisible workload of mothers</a>: 95% of mothers read to children, compared to 67% of fathers. Yet intriguingly, those I surveyed – whose ages ranged from their early 20s to their 70s – collectively talked about books being passed down across eight generations. Family members were associated with their most valued books – and their identities as readers. <h2>Treasured possessions</h2> Books passed down through generations often become treasured possessions, embodying a shared family history. One person discussed an old hardcover copy of <a href="https://www.harpercollins.com.au/9780732284350/blinky-bill/">Blinky Bill</a> by Dorothy Wall. Originally given to her father and his siblings by their great-aunt in 1961, the book’s pages are now discoloured and falling out. “Although I always think of my mother as having been my reading role model,” she wrote, “actually my father had an equally big impact, just in another way.” Her father is a central organising figure on her home bookshelf: she has dedicated a whole shelf to the books he liked. The story she tells about his old copy of Blinky Bill, however, crosses generations. The book’s battered state is a testament to its longevity and well-loved status. Its inscription to her family members makes the copy unique and irreplaceable. Another person remembered a set of Dickens’ novels, complete with margin notes and century-old newspaper clippings, carefully stored with her most special books. These volumes, initially owned by her great-great-grandmother and later gifted by her great-aunt, represent a reading bond passed down through generations. Such books can never be replaced, no matter how many copies might be in circulation. These books are closely associated with memories and experiences – they are invaluable for who they represent. A third person has her father’s “old” Anne McCaffrey’s <a href="https://www.goodreads.com/series/40323-dragonriders-of-pern">Dragonriders of Pern</a> series: he read it to her as a teenager, then passed it down. The book “sparked” her interest in science-fiction, and she now intends to pass it on to her own teenager. Her book, too, is “battered”, with “chunks falling out when you read it”. The cover is falling off. The deteriorating state of a book is part of the book’s legacy. It shows how loved it has been. Reading passions can be deliberately cultivated through family, but their value is less connected to reading comprehension or literacy than a sense of connection through sharing. Inherited, much-loved books bind families together. They can anchor absent family members to the present. These books can come to symbolise love, connection and loss. The family members who’ve passed down their books might not be physically present in children’s lives – they may not be reading aloud to them at bedtime – but through their books, they can have a strong presence in their loved ones’ memories. That indelible trace can be sustained into adulthood. <h2>Buying books for the next generation</h2> Another way relatives contribute to a family reading legacy is by buying new copies of much-loved books for the next generation. Theresa Sheen, from The Quick Brown Fox, a specialist children’s bookstore in Brisbane, notes that customers often ask for copies of books they had when they were younger. They may have read them to their children and now want them for their grandchildren. For example, <a href="https://www.goodreads.com/series/40767-the-baby-sitters-club">The Babysitters Club series</a> by Ann M. Martin was mentioned multiple times as a nostalgic favourite, now being sought after by grandparents. Readers’ habits of re-buying favourite books can affect the publishing industry. With older children’s classics still selling, publishers seek to update the text to reflect contemporary cultural mores. Enid Blyton is one author who endures through intergenerational love and nostalgia. However, her work is regularly <a href="https://www.news.com.au/entertainment/books-magazines/books/enid-blytons-famous-five-books-edited-to-remove-offensive-words/news-story/47a63bb79a5d870f19aed58b19469bb5">edited and bowdlerised</a> to update it. Books can be imbued with the voices and emotions of others. They are more than just physical objects – they are vessels of shared experiences that can be passed down, up and across generations. This enduring bond between family members does more than preserve individual stories. It actively shapes and sustains a vibrant reading culture.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/232372/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/emily-grace-baulch-1399683">Emily Grace Baulch</a>, Producer at Ludo Studio & Freelance Editor, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

I have hay fever. How can I tell what I’m allergic to?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/ryan-mead-hunter-1480189">Ryan Mead-Hunter</a>, <a href="https://theconversation.com/institutions/curtin-university-873">Curtin University</a> When we think of spring we think of warming weather, birdsong and flowers. But for many people, this also means the return of their seasonal hay fever symptoms. Around <a href="https://www.abs.gov.au/statistics/health/health-conditions-and-risks/health-conditions-prevalence/latest-release">24% of Australians</a> get hay fever, with sneezing, a runny or blocked nose, and itchy or watery eyes the most common symptoms. In <a href="https://www.healthdirect.gov.au/hay-fever#:%7E:text=Key%20facts,dust%20mites%2C%20and%20animal%20fur">severe cases</a>, this may impact sleep and concentration, or be linked to increased frequency of sinus infections. The exact timing of the symptoms depends on your exposure to an allergen – the thing you’re allergic to. Those impacted by tree pollen (from plane trees or cypress pine, for example) may experience symptoms at different times of the year than those impacted by grass pollen (such as rye grass). This will also vary around the country. In Perth, for example, tree pollen (cypress pine) is generally present in August to October, while grass pollen counts tend to be highest in October to November. Other cities and regions may have longer pollen seasons, which may extend further into summer. <h2>Remind me, how does hay fever impact the body?</h2> What we know colloquially as hay fever is called allergic rhinitis. Exposure to a specific allergen (or allergens) triggers an immune response in the body. This leads to inflammation and swelling of the tissue lining the nasal passages in the nose. A range of <a href="https://www.healthdirect.gov.au/hay-fever#:%7E:text=Key%20facts,dust%20mites%2C%20and%20animal%20fur.">allergens</a> may trigger such a response: pollen (from trees, grass or weeds), dust mites, pet fur, dander, mould and some air pollutants. Those with allergies that are only present for part of the year, such as pollen, experience what we call seasonal hay fever, while those with allergies that may be present at any time, such as dust mites and pet dander, experience perennial hay fever. <h2>Getting a diagnosis</h2> Many people with hay fever self-manage their symptoms by limiting exposure to allergens and using over-the-counter <a href="https://theconversation.com/how-do-hay-fever-treatments-actually-work-and-whats-best-for-my-symptoms-213071">antihistamines and steroid nasal sprays</a>. But this may require assistance from your GP and confirmation that what you’re experiencing is hay fever. Your GP can assess your symptoms and medical history, provide a diagnosis, and help with treating and managing your symptoms. Your GP may also be able help you identify potential allergens, based on when you experience symptoms and the environments to which you’re exposed. If symptoms persist, your GP may suggest allergy testing. They may refer you to a specialist called an immunologist, to determine what particular allergen is causing your symptoms, using <a href="https://www.allergy.org.au/patients/allergy-testing/allergy-testing">skin prick tests or blood tests</a>. Tests typically involve controlled exposure to small quantities of suspected allergens. But note, there are a number of tests marketed online that are unproven and not recommended by reputable bodies. <h2>How else can I work out what I’m allergic to?</h2> For those with seasonal hay fever, resources are available to help manage exposures, based on the flowering seasons for common allergy-related species or through pollen forecasting services. The Australian Society of Clinical Immunology and Allergy provides a <a href="https://www.allergy.org.au/patients/allergic-rhinitis-hay-fever-and-sinusitis/guide-to-common-allergenic-pollen">useful pollen guide</a> for each species and when they’re most likely to cause symptoms, broken down for each state and territory. Pollen monitoring and forecasting services – such as <a href="https://www.perthpollen.com.au/">Perth Pollen</a>, <a href="https://www.melbournepollen.com.au/">Melbourne Pollen</a> and <a href="https://www.sydneypollen.com.au/">Sydney Pollen</a>, as well as for other cities – can help you plan outdoor activities. There are also associated phone apps for these services, which can give notifications when the pollen count is high. You can down load these apps (such as <a href="https://airrater.org/">AirRater</a>, Perth Pollen, Melbourne Pollen and Sydney Pollen) from your preferred app store. Apps such as <a href="https://airrater.org/">AirRater</a> also allow you to enter information about your symptoms, which can then be matched to the environmental conditions at the time (pollen count, temperature, smoke, and so on). Using statistical modelling, the app may be able to establish a link between symptoms and exposure. If a sufficiently high correlation is established, the app can send you notifications when the <a href="https://airrater.org/how-does-it-work/">exposure risk</a> is high. This may prompt you to limit outdoor activities and have any medication readily available. <hr /> Further information about managing allergic rhinitis is available from <a href="https://www.healthdirect.gov.au/hay-fever">healthdirect</a> and <a href="https://allergyfacts.org.au/__interest/allergic-rhinitis/">Allergy and Anaphylaxis Australia</a> <a href="https://theconversation.com/profiles/ryan-mead-hunter-1480189">Ryan Mead-Hunter</a>, Senior lecturer, School of Population Health, <a href="https://theconversation.com/institutions/curtin-university-873">Curtin University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

"Happy wives, happy social lives?" Men are more emotionally disconnected than women – what can be done about it?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/roger-patulny-94836">Roger Patulny</a>, <a href="https://theconversation.com/institutions/hong-kong-baptist-university-2801">Hong Kong Baptist University</a> Many of us are worried about loneliness and isolation, and both <a href="https://theconversation.com/dont-be-fooled-loneliness-affects-men-too-15545">decade-old</a> and <a href="https://www.relationshipsnsw.org.au/blog/how-many-australians-are-lonely/">recent data</a> suggest they impact men more than women. Loneliness predicts health outcomes including <a href="https://journals.sagepub.com/doi/10.1177/1745691614568352">early mortality</a>, greater <a href="https://hqlo.biomedcentral.com/articles/10.1186/s12955-022-01946-6">psychological distress</a>, and more <a href="https://www.nature.com/articles/s41572-022-00355-9">cardiovascular, metabolic and neurological problems</a>. New research also links loneliness to <a href="https://bmcpublichealth.biomedcentral.com/articles/10.1186/s12889-024-18770-w">more intolerant attitudes towards women</a>. These findings raise concerns over the causes and impacts of men’s loneliness and isolation. <h2>A deep dive into loneliness</h2> I recently analysed more than 50 indicators from a decade of data collected by the <a href="https://www.acspri.org.au/aussa">Australian Social Attitudes Survey</a>, from 2011–12, 2015–16, 2017–18, and 2022–23. My statistical models produced results for (self-identified) men and women, after controlling for the impacts of age, employment and partner status. I confirmed that Australian men are more likely to be socially and emotionally disconnected than women. I also found some reasons why this might be the case. I found men appear to focus their emotional energies primarily on their nuclear families and partners. Consequently, they over-rely on their female partners for intimate support and develop more distant, limited and transactional relationships with other people – and other men. <h2>Men are more emotionally disconnected</h2> The data show men continue to lack emotional support on a range of indicators. This puts them at greater risk of health impacts and potentially encourages more toxic attitudes towards women. A significantly greater proportion of men than women reported: <ul> <li>receiving no support from their closest friend</li> <li>receiving fun/practical advice over emotional support from close friends</li> <li>having less contact with a close friend</li> <li>not having anyone for emotional support</li> <li>not feeling “very close” to their closest friend</li> <li>not feeling “love” as their most commonly experienced emotion in the last week.</li> </ul> <h2>Men have more distant, transactional relationships</h2> Why are men in this situation? Masculinity roles are clearly influential. Traditional masculinity encourages men to appear capable, controlled and independent, avoid displays of “vulnerable” emotions or male-to-male affection (like hugging, touch or crying), and embrace the hetero-normative ideal of male provision and leadership. Such norms have been found to constrain male intimacy <a href="https://pubmed.ncbi.nlm.nih.gov/37531906/">by disallowing vulnerability</a>. My data show men tend to develop looser, transactional ties with more distant people. This may reduce the quality of the connection and its potential to reduce loneliness. I have found men are more likely than women to: <ul> <li>think it is OK to befriend someone just because they’ll make a “useful” contact</li> <li>feel obligated to repay favours immediately (foregoing longer-term connections)</li> <li>be kind to others because they “value doing the right thing”, rather than because they empathically connect with or care about the person</li> <li>give and receive kindness from strangers (rather than more familiar people)</li> <li>seek help with household jobs from more distant family or friends</li> <li>seek practical support (money, advice) from private and commercial sources (rather than friends or family)</li> <li>not seek help from family or friends for emotional, sickness or care issues.</li> </ul> This means many men retain an individualist masculine desire to remain emotionally aloof. <hr /> <iframe id="TBJfz" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/TBJfz/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe> <hr /> <h2>Appearing in control but becoming dependent?</h2> So where do men turn for intimate, emotional connection? Most often, their families. Prior studies show partnered men are <a href="https://bmcpublichealth.biomedcentral.com/articles/10.1186/s12889-024-18770-w">less lonely than single men</a>. My data show men revere the nuclear family institution and the core supportive role of women and female partners. Men are more likely than women to: <ul> <li>believe having children increases their social standing</li> <li>believe family is more important than friends</li> <li>rely on family over friends for support</li> <li>have mixed-gender friendships (in contrast to womens’ predominately female friendships)</li> <li>see their (predominantly female) partner as their closest friend</li> <li>emotionally support their (predominantly female) partner ahead of supporting others.</li> </ul> However, the masculine desire to be a “good nuclear family man” <a href="https://pubmed.ncbi.nlm.nih.gov/37531906/">can both support and impede</a> men’s social connection. Partnered men might feel less lonely but that doesn’t mean they give or gain sufficient emotional support from their nuclear families. My data show men are less likely than women to: <ul> <li>plan or organise social and family activities</li> <li>have at least weekly contact with non-nuclear family or friends</li> <li>emotionally support their friends, family or children ahead of their partners</li> <li>have their partner support them ahead of others (women were more likely to support their children first).</li> </ul> This raises several issues. If men cling to the notion that their primary role is to provide for and support their (female) partner – while she in turn emotionally supports everyone else – they risk becoming personally isolated through diminished networks and outmoded expectations. In this context, men who believe they should earn more than their partners <a href="https://theconversation.com/loneliness-in-the-workplace-is-greatest-among-men-with-traditional-views-about-being-the-breadwinner-230535">are lonelier</a> than other men.

Retiring early can be bad for the brain

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/plamen-v-nikolov-1112610">Plamen V Nikolov</a>, <a href="https://theconversation.com/institutions/binghamton-university-state-university-of-new-york-2252">Binghamton University, State University of New York</a> The <a href="https://theconversation.com/us/topics/research-brief-83231">Research Brief</a> is a short take about interesting academic work. <h2>The big idea</h2> People who retire early suffer from accelerated cognitive decline and may even encounter early onset of dementia, according to a I conducted with my doctoral student <a href="https://sites.google.com/binghamton.edu/alan-adelman/home">Alan Adelman</a>. To establish that finding, we examined the effects of a rural pension program China introduced in 2009 that provided people who participated with a stable income if they stopped working after the official retirement age of 60. We found that people who participated in the program and retired within one or two years experienced a cognitive decline equivalent to a drop in general intelligence of 1.7% relative to the general population. This drop is equivalent to about three IQ points and could make it harder for someone to <a href="https://doi.org/10.1017/S0033291700008412">adhere to a medication schedule</a> or <a href="https://doi.org/10.1111/j.1475-%205890.2007.00052.x">conduct financial planning</a>. The largest negative effect was in what is called “delayed recall,” which measures a person’s ability to remember something mentioned several minutes ago. Neurological research <a href="https://doi.org/10.1001/archneur.1991.00530150046016">links problems in this area to an early onset of dementia</a>. <h2>Why it matters</h2> Cognitive decline refers to when a person has trouble remembering, learning new things, concentrating or making decisions that affect their everyday life. Although some cognitive decline appears to be an inevitable byproduct of aging, faster decline can have profound adverse consequences on one’s life. Better understanding of the causes of this has powerful financial consequences. Cognitive skills – the mental processes of gathering and processing information to solve problems, adapt to situations and learn from experiences – are crucial for decision-making. They influence an individual’s ability to process information and <a href="https://www.jstor.org/stable/1818642">are connected to higher earnings</a> and a <a href="https://www.doi.org/10.1257/jep.25.1.159">better quality of life</a>. Retiring early and working less or not at all can generate large benefits, such as reduced stress, better diets and more sleep. But as we found, it also has unintended adverse effects, like fewer social activities and less time spent challenging the mind, that far outweighed the positives. While retirement schemes like the 401(k) and similar programs in other countries <a href="https://www.doi.org/10.1023/B:PUCH.0000035859.20258.e0">are typically introduced to ensure the welfare of aging adults</a>, our research suggests they need to be designed carefully to avoid unintended and significant adverse consequences. When people consider retirement, they should weigh the benefits with the significant downsides of a sudden lack of mental activity. A good way to ameliorate these effects is to stay engaged in social activities and continue to use your brains in the same way you did when you were working. In short, we show that if you rest, you rust. <h2>What still isn’t known</h2> Because we are using data and a program in China, the mechanisms of how retirement induces cognitive decline could be context-specific and may not necessarily apply to people in other countries. For example, cultural differences or other policies that can provide support to individuals in old age can buffer some of the negative effects that we see in rural China due to the increase in social isolation and reduced mental activities. Therefore, we can not definitively say that the findings will extrapolate to other countries. We are looking for data from other countries’ retirement programs, such as India’s, to see if the effects are similar or how they are different. <h2>How I do my research</h2> A big focus of the <a href="https://scholar.harvard.edu/pnikolov/my-research-group-1">economics research lab</a> I run is to <a href="http://www.nber.org/%7Enikolovp/research.html">better understand</a> the causes and consequences of changes in what economists call <a href="https://www.britannica.com/topic/human-capital">“human capital”</a> – especially cognitive skills – in the context of developing countries. Our lab’s mission is to generate research to inform economic policies and empower individuals in low-income countries to rise out of poverty. One of the main ways we do this is through the use of randomized controlled trials to measure the impact of a particular intervention, such as retiring early or access to microcredit, on education outcomes, productivity and health decisions. <a href="https://theconversation.com/profiles/plamen-v-nikolov-1112610">Plamen V Nikolov</a>, Assistant Professor of Economics, <a href="https://theconversation.com/institutions/binghamton-university-state-university-of-new-york-2252">Binghamton University, State University of New York</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Eight simple changes to our neighbourhoods can help us age well

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/jerome-n-rachele-251972">Jerome N Rachele</a>, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a>; <a href="https://theconversation.com/profiles/james-f-sallis-407885">James F Sallis</a>, <a href="https://theconversation.com/institutions/university-of-california-san-diego-1314">University of California, San Diego</a>, and <a href="https://theconversation.com/profiles/venurs-loh-118864">Venurs Loh</a>, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a> Where we live can play a big part in ageing well, largely because of the links between physical activity and wellbeing. <a href="https://www.ahuri.edu.au/__data/assets/pdf_file/0012/2181/AHURI_Final_Report_No214_Downsizing-amongst-older-Australians.pdf">Research shows</a> that two-thirds of Australians prefer to age in place. That is, we want to live independently in our homes for as long as we can. Our neighbourhoods and their design can then improve or hinder our ability to get out of the house and be physically active. The rapid ageing of Australia’s population only adds to the importance of neighbourhood design. In 2016, 15% of Australians were aged 65 or older. That proportion is <a href="https://www.aihw.gov.au/reports-statistics/population-groups/older-people/overview">projected to double</a> by 2056. These trends present several <a href="https://www.aihw.gov.au/reports-statistics/population-groups/older-people/reports">social and economic challenges</a>, particularly for the health sector. Designing neighbourhoods in ways that promote physical activity can help overcome these challenges. <h2>Eight simple steps</h2> The following is a short list of <a href="https://ijbnpa.biomedcentral.com/articles/10.1186/s12966-017-0471-5">evidence-based steps</a> local and state governments can take to assist older people to be physically active. These involve minor but effective changes to neighbourhood design. Improve footpaths: Research indicates that older people have a <a href="https://theconversation.com/why-older-people-get-osteoporosis-and-have-falls-68145">higher risk of falls</a>. Ensuring footpaths are level and crack-free, and free from obstructions, will encourage walking among older people – especially those with a disability. Connected pedestrian networks: Introducing footpaths at the end of no-through-roads and across long street blocks reduces walking distances to destinations. This makes walking a more viable option. Slowing traffic in high-pedestrian areas: Slowing traffic <a href="https://www.heartfoundation.org.au/images/uploads/publications/Safe-Speed-Evidence-Report.pdf">improves safety</a> by reducing the risk of a collision. It also reduces the risk of <a href="https://www.ncbi.nlm.nih.gov/pubmed/28557669">death and serious injury</a> in the event of a collision. Age-friendly street crossings: Installing longer pedestrian crossing light sequences gives older pedestrians <a href="https://academic.oup.com/ageing/article/41/5/690/47318/Most-older-pedestrians-are-unable-to-cross-the">more time to cross</a>, and installing refuge islands means those who walk more slowly can cross the street in two stages. Disabled access at public transport: Although a form of motorised transport, public transport users undertake more incidental physical activity compared with car users. This is because they walk between transit stops and their origins and destinations. Improving disabled access helps make public transport a viable option for more older people. Places to rest: <a href="https://bmcpublichealth.biomedcentral.com/articles/10.1186/1471-2458-13-1054">Providing rest spots</a> such as benches enables older people to break up their walk and rest when needed. Planting trees: Planting trees <a href="http://www.sciencedirect.com/science/article/pii/S0277953614004109?via%3Dihub">creates more pleasant scenery</a> to enjoy on a walk. It also provides shade on hot days. Improving safety: Ensuring that streets are well-lit and reducing graffiti and signs of decay are likely to <a href="https://www.ncbi.nlm.nih.gov/pubmed/24552845">improve perceptions of safety</a> among older people. <h2>Why physical activity matters</h2> Physical function – the ability to undertake everyday activities such as walking, bathing and climbing stairs – often declines as people age. The reason for this is that ageing is often accompanied by a reduction in muscle strength, flexibility and cardiorespiratory reserves. Regular physical activity can <a href="https://www.ncbi.nlm.nih.gov/pubmed/14552936">prevent or slow the decline</a> in physical function, even among those with existing health conditions. Middle-to-older aged adults can reduce their risk of physical function decline <a href="https://ijbnpa.biomedcentral.com/articles/10.1186/1479-5868-7-38">by 30%</a> with regular physical activity (at least 150 minutes per week). This includes recreational physical activity, like walking the dog, or incidental physical activity, such as walking to the shops or to visit friends. By making minor changes as outlined above, the health and longevity of our elderly population can be extended. Such changes will help our elderly age well in place. <a href="https://theconversation.com/profiles/jerome-n-rachele-251972">Jerome N Rachele</a>, Research Fellow in Social Epidemiology, Institute for Health and Ageing, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a>; <a href="https://theconversation.com/profiles/james-f-sallis-407885">James F Sallis</a>, Professorial Fellow, Institute for Health and Ageing, Australian Catholic University, and Emeritus Professor, Department of Family Medicine and Public Health, <a href="https://theconversation.com/institutions/university-of-california-san-diego-1314">University of California, San Diego</a>, and <a href="https://theconversation.com/profiles/venurs-loh-118864">Venurs Loh</a>, PhD Candidate, Institute for Health and Ageing, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

I have a stuffy nose, how can I tell if it’s hay fever, COVID or something else?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/deryn-thompson-1449312">Deryn Thompson</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> Hay fever (also called allergic rhinitis) affects <a href="https://www.abs.gov.au/statistics/health/health-conditions-and-risks/national-health-survey-state-and-territory-findings/latest-release">24%</a> of Australians. <a href="https://www.allergy.org.au/patients/allergic-rhinitis-hay-fever-and-sinusitis/allergic-rhinitis-or-hay-fever">Symptoms</a> include sneezing, a runny nose (which may feel blocked or stuffy) and itchy eyes. People can also experience an itchy nose, throat or ears. But COVID is still <a href="https://theconversation.com/xec-is-now-in-australia-heres-what-we-know-about-this-hybrid-covid-variant-239292">spreading</a>, and <a href="https://theconversation.com/i-feel-sick-how-do-i-know-if-i-have-the-flu-covid-rsv-or-something-else-234266">other viruses</a> can cause cold-like symptoms. So how do you know which one you’ve got? <h2>Remind me, how does hay fever cause symptoms?</h2> <a href="https://www.allergy.org.au/hp/papers/allergic-rhinitis-clinical-update">Hay fever</a> happens when a person has become “sensitised” to an allergen trigger. This means a person’s body is always primed to react to this trigger. Triggers can include allergens in the air (such as pollen from trees, grasses and flowers), mould spores, animals or house dust mites which mostly live in people’s mattresses and bedding, and feed on shed skin. When the body is exposed to the trigger, it produces IgE (immunoglobulin E) antibodies. These cause the release of many of the body’s own chemicals, including histamine, which result in hay fever symptoms. People who have asthma may find their asthma symptoms (cough, wheeze, tight chest or trouble breathing) worsen when exposed to airborne allergens. Spring and sometimes into summer can be the worst time for people with grass, tree or flower allergies. However, animal and house dust mite symptoms usually happen year-round. <h2>What else might be causing my symptoms?</h2> Hay fever does not cause a fever, sore throat, muscle aches and pains, weakness, loss of taste or smell, nor does it cause you to cough up mucus. These symptoms are likely to be caused by a virus, such as COVID, influenza, respiratory syncytial virus (RSV) or a “cold” (often caused by rhinoviruses). These conditions can occur all year round, with some overlap of symptoms: <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/624085/original/file-20241007-16-xf6euv.png?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/624085/original/file-20241007-16-xf6euv.png?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/624085/original/file-20241007-16-xf6euv.png?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=582&fit=crop&dpr=1 600w, https://images.theconversation.com/files/624085/original/file-20241007-16-xf6euv.png?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=582&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/624085/original/file-20241007-16-xf6euv.png?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=582&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/624085/original/file-20241007-16-xf6euv.png?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=731&fit=crop&dpr=1 754w, https://images.theconversation.com/files/624085/original/file-20241007-16-xf6euv.png?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=731&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/624085/original/file-20241007-16-xf6euv.png?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=731&fit=crop&dpr=3 2262w" alt="" /></a><figcaption><a class="source" href="https://theconversation.com/i-feel-sick-how-do-i-know-if-i-have-the-flu-covid-rsv-or-something-else-234266">Natasha Yates/The Conversation</a></figcaption></figure> COVID still <a href="https://theconversation.com/xec-is-now-in-australia-heres-what-we-know-about-this-hybrid-covid-variant-239292">surrounds</a> us. <a href="https://www.sahealth.sa.gov.au/wps/wcm/connect/public+content/sa+health+internet/about+us/health+statistics/surveillance+of+notifiable+conditions/respiratory+infections+dashboard">RSV and influenza</a> rates appear higher than before the COVID pandemic, but it may be <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10888990/#:%7E:text=Increases%20in%20RSV%20patient%20volume,with%20an%20RSV%20diagnosis%20occurred">due to more testing</a>. So if you have a fever, sore throat, muscle aches/pains, weakness, fatigue, or are coughing up mucus, stay home and avoid mixing with others to limit transmission. People with COVID symptoms can take a rapid antigen test (<a href="https://www.health.gov.au/sites/default/files/2024-04/coronavirus-covid-19-rapid-antigen-tests.pdf">RAT</a>), ideally when <a href="https://www.cochrane.org/CD013705/INFECTN_how-accurate-are-rapid-antigen-tests-diagnosing-covid-19">symptoms start</a>, then isolate until symptoms disappear. <a href="https://www.mja.com.au/journal/2023/219/11/covid-19-rapid-antigen-tests-approved-self-testing-australia-published">One negative RAT alone</a> can’t rule out COVID if symptoms are still present, so test again 24–48 hours after your initial test if symptoms persist. You can now test yourself for COVID, RSV and influenza in a <a href="https://www.tga.gov.au/sites/default/files/2024-02/covid-19-rapid-antigen-self-tests-are-approved-australia-ifu-406813.PDF">combined RAT</a>. But again, a negative test doesn’t rule out the virus. If your symptoms continue, <a href="https://www.tga.gov.au/sites/default/files/2024-02/covid-19-rapid-antigen-self-tests-are-approved-australia-ifu-406813.PDF">test again</a> 24–48 hours after the previous test. <h2>If it’s hay fever, how do I treat it?</h2> Treatment involves blocking the body’s histamine release, by taking antihistamine medication which helps reduce the symptoms. Doctors, nurse practitioners and pharmacists can develop a <a href="https://www.allergy.org.au/images/pc/ASCIA_Allergic_Rhinitis_Treatment_Plan_2024.pdf">hay fever care plan</a>. This may include using a nasal spray containing a topical corticosteroid to help reduce the swelling inside the nose, which causes stuffiness or blockage. Nasal sprays need to delivered <a href="https://allergyfacts.org.au/are-you-using-your-nasal-spray-correctly/">using correct technique</a> and used over several weeks to work properly. Often these sprays can also help lessen the itchy eyes of hay fever. Drying bed linen and pyjamas inside during spring can <a href="https://www.allergy.org.au/patients/allergy-treatments/allergen-minimisation">lessen symptoms</a>, as can putting a <a href="https://www.nps.org.au/consumers/managing-hay-fever">smear of Vaseline</a> in the nostrils when going outside. Pollen sticks to the Vaseline, and gently blowing your nose later removes it. People with asthma should also have an <a href="https://asthma.org.au/manage-asthma/asthma-action-plan/">asthma plan</a>, created by their doctor or nurse practitioner, explaining how to adjust their asthma reliever and preventer medications in hay fever seasons or on allergen exposure. People with asthma also need to be <a href="https://www.nationalasthma.org.au/living-with-asthma/resources/patients-carers/factsheets/thunderstorm-asthma">alert for thunderstorms</a>, where pollens can burst into tinier particles, be inhaled deeper in the lungs and cause a severe asthma attack, and even death. <h2>What if it’s COVID, RSV or the flu?</h2> Australians aged 70 and over and others with underlying health conditions who test positive for COVID are <a href="https://www.healthdirect.gov.au/covid-19/medications#at-home">eligible for antivirals</a> to reduce their chance of severe illness. Most other people with COVID, RSV and influenza will recover at home with rest, fluids and paracetamol to relieve symptoms. However some groups are at greater risk of serious illness and may require additional treatment or hospitalisation. For <a href="https://www.health.nsw.gov.au/Infectious/factsheets/Pages/respiratory-syncytial-virus.aspx">RSV</a>, this includes premature infants, babies 12 months and younger, children under two who have other medical conditions, adults over 75, people with heart and lung conditions, or health conditions that lessens the immune system response. For influenza, people at <a href="https://www.health.nsw.gov.au/Infectious/Influenza/Pages/at-risk.aspx">higher risk</a> of severe illness are pregnant women, Aboriginal people, people under five or over 65 years, or people with long-term medical conditions, such as kidney, heart, lung or liver disease, diabetes and decreased immunity. If you’re concerned about severe symptoms of COVID, RSV or influenza, consult your doctor or call 000 in an emergency. If your symptoms are mild but persist, and you’re not sure what’s causing them, book an appointment with your doctor or nurse practitioner. Although hay fever season is here, we need to avoid spreading other serious infectious.

How can we improve public health communication for the next pandemic? Tackling distrust and misinformation is key

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/shauna-hurley-203140">Shauna Hurley</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> and <a href="https://theconversation.com/profiles/rebecca-ryan-1522824">Rebecca Ryan</a>, <a href="https://theconversation.com/institutions/la-trobe-university-842">La Trobe University</a> There’s a common thread linking our <a href="https://www.visualcapitalist.com/history-of-pandemics-deadliest/">experience of pandemics</a> over the past 700 years. From the black death in the 14th century to COVID in the 21st, public health authorities have put emergency measures such as isolation and quarantine in place to stop infectious diseases spreading. As we know from COVID, these measures upend lives in an effort to save them. In both the <a href="https://www.thinkglobalhealth.org/article/pandemic-protests-when-unrest-and-instability-go-viral">recent</a> and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3559034/">distant past</a> they’ve also given rise to collective unrest, confusion and resistance. So after all this time, what do we know about the role public health communication plays in helping people understand and adhere to protective measures in a crisis? And more importantly, in an age of misinformation and distrust, how can we improve public health messaging for any future pandemics? Last year, we published a <a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD015144/full">Cochrane review</a> exploring the global evidence on public health communication during COVID and other infectious disease outbreaks including SARS, MERS, influenza and Ebola. Here’s a snapshot of what we found. <h2>The importance of public trust</h2> A key theme emerging in analysis of the COVID pandemic globally is public trust – or lack thereof – in governments, public institutions and science. Mounting evidence suggests <a href="https://www.washingtonpost.com/world/2022/02/01/trust-lancet-covid-study/">levels of trust in government</a> were <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(22)00172-6/fulltext">directly proportional</a> to fewer COVID infections and higher vaccination rates across the world. It was a crucial factor in people’s willingness to follow public health directives, and is now a key focus for future pandemic preparedness. Here in Australia, public trust in governments and health authorities steadily eroded over time. Initial information from governments and health authorities about the unfolding COVID crisis, personal risk and mandated protective measures was generally clear and consistent across the country. The establishment of the <a href="https://www.aph.gov.au/About_Parliament/Parliamentary_Departments/Parliamentary_Library/pubs/rp/rp1920/Quick_Guides/AustralianCovid-19ResponseManagement#_Toc38973752">National Cabinet</a> in 2020 signalled a commitment from state, territory and federal governments to consensus-based policy and public health messaging. During this early phase of relative unity, <a href="https://theconversation.com/inflation-covid-inequality-new-report-shows-australias-social-cohesion-is-at-crossroads-195198">Australians reported</a> higher levels of belonging and trust in government. But as the pandemic wore on, public trust and confidence fell on the back of conflicting state-federal pandemic strategies, blame games and the <a href="https://theconversation.com/we-lost-the-plot-on-covid-messaging-now-governments-will-have-to-be-bold-to-get-us-back-on-track-186732">confusing fragmentation</a> of public health messaging. The divergence between <a href="https://www.theaustralian.com.au/nation/tale-of-two-cities-gripped-by-covid-fear-outbreak/news-story/cf1b922610aeb0b0ee9b0b53486bf640">lockdown policies and public health messaging</a> adopted by <a href="https://www.theage.com.au/national/victoria/a-tale-of-two-cities-that-doesn-t-seem-fair-20211012-p58z79.html">Victoria and New South Wales</a> is one example, but there are plenty of others. When state, territory and federal governments have conflicting policies on protective measures, people are easily confused, lose trust and become harder to engage with or persuade. Many tune out from partisan politics. Adherence to mandated public health measures falls. Our research found clarity and consistency of information were key features of effective public health communication throughout the COVID pandemic. We also found public health communication is most effective when authorities work in partnership with different target audiences. In Victoria, the case brought against the state government for the <a href="https://www.abc.net.au/news/2023-07-24/melbourne-public-housing-tower-covid-lockdown-compensation/102640898">snap public housing tower lockdowns</a> is a cautionary tale underscoring how essential considered, tailored and two-way communication is with diverse communities. <h2>Countering misinformation</h2> Misinformation is <a href="https://reutersinstitute.politics.ox.ac.uk/hydroxychloroquine-australia-cautionary-tale-journalists-and-scientists">not a new problem</a>, but has been supercharged by the advent of <a href="https://theconversation.com/health-misinformation-is-rampant-on-social-media-heres-what-it-does-why-it-spreads-and-what-people-can-do-about-it-217059">social media</a>. The much-touted “miracle” drug <a href="https://www.vox.com/future-perfect/22663127/ivermectin-covid-treatments-vaccines-evidence">ivermectin</a> typifies the extraordinary traction unproven treatments gained locally and globally. Ivermectin is an anti-parasitic drug, lacking evidence for viruses like COVID. Australia’s drug regulator was forced to <a href="https://www.theguardian.com/australia-news/2021/sep/10/australian-drug-regulator-bans-ivermectin-as-covid-treatment-after-sharp-rise-in-prescriptions">ban ivermectin presciptions</a> for anything other than its intended use after a <a href="https://www.theguardian.com/world/2021/aug/30/australian-imports-of-ivermectin-increase-10-fold-prompting-warning-from-tga">sharp increase</a> in people seeking the drug sparked national shortages. Hospitals also reported patients <a href="https://www.theguardian.com/australia-news/2021/sep/02/sydney-covid-patient-in-westmead-hospital-after-overdosing-on-ivermectin-and-other-online-cures">overdosing on ivermectin</a> and cocktails of COVID “cures” promoted online. The <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(22)01585-9/fulltext">Lancet Commission</a> on lessons from the COVID pandemic has called for a coordinated international response to countering misinformation. As part of this, it has called for more accessible, accurate information and investment in scientific literacy to protect against misinformation, including that shared across social media platforms. The World Health Organization is developing resources and recommendations for health authorities to address this “<a href="https://www.who.int/health-topics/infodemic#tab=tab_1">infodemic</a>”. National efforts to directly tackle misinformation are vital, in combination with concerted efforts to raise health literacy. The Australian Medical Association has <a href="https://www.ama.com.au/media/action-needed-tackle-health-misinformation-internet-social-media">called on the federal government</a> to invest in long-term online advertising to counter health misinformation and boost health literacy. People of all ages need to be equipped to think critically about who and where their health information comes from. With the rise of AI, this is an increasingly urgent priority. <h2>Looking ahead</h2> Australian health ministers recently <a href="https://www.cdc.gov.au/newsroom/news-and-articles/australian-health-ministers-reaffirm-commitment-australian-cdc">reaffirmed their commitment</a> to the new Australian Centre for Disease Control (CDC). From a science communications perspective, the Australian CDC could provide an independent voice of evidence and consensus-based information. This is exactly what’s needed during a pandemic. But full details about the CDC’s funding and remit have been the subject of <a href="https://www.croakey.org/federal-budget-must-deliver-on-climate-health-and-the-centre-for-disease-control-sector-leaders-warn/">some conjecture</a>. Many of our <a href="https://www.cochraneaustralia.org/articles/covidandcommunications">key findings</a> on effective public health communication during COVID are not new or surprising. They reinforce what we know works from previous disease outbreaks across different places and points in time: tailored, timely, clear, consistent and accurate information. The rapid rise, reach and influence of misinformation and distrust in public authorities bring a new level of complexity to this picture. Countering both must become a central focus of all public health crisis communication, now and in the future.

How can I stop using food to cope with negative emotions?

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/inge-gnatt-1425767">Inge Gnatt</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a> Have you ever noticed changes in your eating habits when you are sad, bored or anxious? Many people report eating either more, or less, as a way of helping them to cope when they experience difficult emotions. Although this is a very normal response, it can take the pleasure out of eating, and can become distressing and bring about other feelings of <a href="https://doi.org/10.1016/j.eatbeh.2018.02.008">shame and self-criticism</a>. Adding to the complexity of it all, we live in a world where <a href="https://butterfly.org.au/diet-culture-101/">diet culture</a> is unavoidable, and our relationship to eating, food and body image can become complicated and confusing. <h2>Emotional eating is common</h2> “Emotional eating” refers to the eating behaviours (typically eating more) that occur in response to difficult emotions. <a href="https://doi.org/10.3390/ijerph18041744">Research shows</a> around 20% of people regularly engage in emotional eating, with a higher prevalence <a href="https://doi.org/10.1371/journal.pone.0285446">among adolescents</a> and women. In a <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0285446#sec012">study</a> of more than 1,500 adolescents, 34% engaged in emotional eating while sad and 40% did so while anxious. Foods consumed are often fast-foods and other energy-dense, nutrient-poor convenience foods. <h2>Stress, strong emotions and depression</h2> For some people, emotional eating was simply a <a href="https://doi.org/10.1038/s41598-017-09519-0">habit formed earlier in life</a> that has persisted over time. But other factors might also contribute to the likelihood of emotional eating. The physiological effects of stress and strong emotions, for example, can influence hormones such as <a href="https://doi.org/10.1016/S0306-4530(00)00035-4">cortisol, insulin and glucose</a>, which can also increase appetite. Increased impulsivity (<a href="https://doi.org/10.1176/appi.ajp.158.11.1783">behaving</a> before thinking things through), vulnerability to depression, a tendency to ruminate and <a href="https://doi.org/10.1080/1047840X.2014.940781">difficulties regulating emotions</a> also <a href="https://doi.org/10.1097/FBP.0b013e328357bd4e">increase the likelihood</a> of emotional eating. <h2>So what do you do?</h2> First, know that fluctuations in eating are normal. However, if you find that the way you eat in response to difficult emotions is not working for you, there are a few things you can do. Starting with small things that are achievable but can have a huge impact, such as prioritising <a href="https://theconversation.com/no-sleep-challenge-the-dangers-of-sleep-deprivation-236608">getting enough sleep</a> and <a href="https://insideoutinstitute.org.au/podcasts/episode-3-the-mindful-dietitian-fiona-sutherland">eating regularly</a>. Then, you can start to think about how you handle your emotions and hunger cues. <h2>Expand your emotional awareness</h2> Often we label emotions as good or bad, and this can result in fear, avoidance, and <a href="https://youtu.be/NDQ1Mi5I4rg?si=lv9d8qjUThSsemXG">unhelpful coping strategies</a> such as emotional eating. But it’s also important to <a href="https://www.pspnet.ca/assets/the-gottman-institute-the-feeling-wheel-v2.pdf">differentiate</a> the exact emotion. This might be feeling isolated, powerless or victimised, rather than something as broad as sad. By <a href="https://headspace.org.au/online-and-phone-support/interactive-tools/activities/understanding-emotions/">noticing</a> what the emotion is, we can bring curiosity to what it means, how we feel in our minds and bodies, and how we think and behave in response. <h2>Tap into your feelings of hunger and fullness</h2> Developing an intuitive way of eating is another helpful strategy to promote <a href="https://insideoutinstitute.org.au/blog/what-is-normal-eating">healthy eating behaviours</a>. Intuitive eating means recognising, understanding and responding to internal signals of hunger and fullness. This might mean tuning in to and acknowledging physical hunger cues, responding by eating food that is nourishing and enjoyable, and identifying sensations of fullness. Intuitive eating <a href="https://doi.org/10.1002/eat.23509">encourages flexibility</a> and thinking about the pleasure we get from food and eating. This style of eating also allows us to enjoy eating out with friends, and sample local delicacies when travelling. It can also reduce the psychological distress from feeling out of control with your <a href="https://doi.org/10.1016/j.jand.2013.12.024">eating</a> habits and the associated negative <a href="https://doi.org/10.1016/j.appet.2015.10.012">body image</a>. <h2>When is it time to seek help?</h2> For some people, the thoughts and behaviours relating to food, eating and body image can negatively impact their life. Having the support of friends and family, accessing <a href="https://nedc.com.au/eating-disorder-resources/interactive-digital-resource-for-eating-disorders">online resources</a> and, in some instances, seeing a trained professional, can be very helpful. There are many <a href="https://doi.org/10.1007/s00787-020-01498-4">therapeutic interventions</a> that work to <a href="https://doi.org/10.1016/j.copsyc.2015.02.010">improve aspects</a> associated with emotional eating. These will depend on your situation, needs, stage of life and other factors, such as whether you are <a href="https://nedc.com.au/eating-disorders/types/neurodivergence">neurodivergent</a>. The best approach is to engage with someone who can bring compassion and understanding to your personal situation, and work with you collaboratively. This work might include: <ul> <li>unpacking some of the patterns that could be underlying these emotions, thoughts and behaviours</li> <li>helping you to discover your emotions</li> <li>supporting you to process other experiences, such as trauma exposure</li> <li>developing a more flexible and intuitive way of eating.</li> </ul> One of the dangers that can occur in response to emotional eating is the temptation to diet, which can lead to disordered eating, and eating disorder behaviours. Indicators of a potential <a href="https://nedc.com.au/eating-disorders/eating-disorders-explained/whats-an-eating-disorder">eating disorder</a> can include: <ul> <li>recent rapid weight loss</li> <li>preoccupation with weight and shape (which is usually in contrast to other people’s perceptions)</li> <li>eating large amounts of food within a short space of time (two hours or less) and feeling a sense of loss of control</li> <li>eating in secret</li> <li>compensating for food eaten (with vomiting, exercise or laxatives).</li> </ul> <a href="https://nedc.com.au/eating-disorders/treatment-and-recovery/treatment-options">Evidence-based approaches</a> can support people experiencing eating disorders.

"Can you sleep at night?" Frustrated shopper confronts Woolies CEO over price gouging

A frustrated Woolworths shopper has called out the supermarket's CEO in store to demand answers about Woolies' record-breaking profits during the cost of living crisis. Chief executive Amanda Bardwell was walking around a Woolworths store in Wollongong when the heated exchange took place, with the whole thing captured on camera. The customer fired off hard-hitting questions to the CEO and other senior staff members, asking, "What do you have to say to the fact that your company is profiting off price gouging during the cost of living crisis?" Ms Bardwell, looking visibly shocked by the confrontation, replied, "Thank you for reaching out to us, we're doing everything we can to recognise that customers are doing it tough to make sure that they're able to get great prices." The woman didn't accept her answer, firing back, "I really don't believe that. Millions of people in Australia right now have to skip meals in order to survive, while you continue to make big bucks and working class people suffer. Can you sleep at night knowing that?" Ms Bardwell replied, "Our team are doing everything that we can to support our customers. We understand that it is an incredibly difficult time right now." A staff member then intervened, adding, "We have lowered prices and you see that right throughout our store… that's great value for our customers." Ms Bardwell thanked the customer for sharing her views and said Woolworths was doing "everything we can" to keep prices low for customers, before another staff member chimed in to say "It's actually illegal to film people in NSW without permission, with the CEO walking away. Social media users were quick to praise the woman for confronting Miss Bardwell, while sharing their own stories of being stung by hefty supermarket prices. "I'm sick of paying nearly $300 a week on groceries. That's choosing the cheapest products. My fridge still looks half empty when I unpack," one said. "I'm sure Coles and Woolworth management don't have cost of living crisis as they are getting bigger and bigger bonus year after year," a second wrote. Others took aim at one particular comment in the video, pointing out, "'It’s illegal to film in NSW without permission', yet Woolworths has how many cameras in every store? Cameras in people’s faces in self serve on every screen. Did they get our permission?" Another added, "If only their empathy was as big as their prices." Image credits: TikTok

How you can get the official Australian portraits of The King and Queen

Royal fans nationwide can now request a special keepsake online for free. All Australians are entitled to their very own free portrait of King Charles and Queen Camilla. The way one can obtain the monarchy keepsake is through sending an email to their local federal MP requesting one. The initiative comes under the constituents' request program, which allows registered Australian voters to receive their own printed portrait of the royals. Official portraits of the King and Queen were provided to the Australian Government by Buckingham Palace in July and are available for public access. Photos available include a photo of the royal couple standing together, and seperate ones of the monarch and her majesty posing alone. In the photos the King and Queen both donned royal blue outfits and their Commonwealth Insignia, with the King wearing The Sovereign's Badge of the Order of Australia and the Queen wearing the Wattle Brooch. The portraits were taken by royal photographer Millie Pilkington in Buckingham Palace's White Drawing Room in June. The digital images can be downloaded for free from the Department of the Prime Minister and Cabinet <a href="https://www.pmc.gov.au/government/official-australian-portraits-king-and-queen" target="_blank" rel="noopener">website</a> for private use. Those who want a physical copy can request printed versions through their Federal Member of the House of Representatives or Senator in their state or territory via email. The government-funded program, introduced in the Parliamentary Entitles Act 1990, is available for Australian citizens only. Image: Department of the Prime Minister and Cabinet/ Millie Pilkington

New research proves travelling can slow down the ageing process

It turns out that going on holiday is good for you in more ways than one. According to new research conducted at Edith Cowan University in Western Australia, travelling can actually slow the ageing process both physically and mentally. The study, published in the <a title="Journal of Travel Research" href="https://journals.sagepub.com/doi/10.1177/00472875241269892#:~:text=The%20principle%20of%20entropy%20increase%20provides%20a%20dynamic%20perspective%20to,Silva%20%26%20Annamalai%2C%202008)." target="_blank" rel="noopener">Journal of Travel Research</a>, is believed to be the first-ever that applied the theory of entropy - the general trend of the universe towards death and disorder – to tourism. "Tourism isn't just about leisure and recreation. It could also contribute to people's physical and mental health," ECU PhD candidate Fangli Hu said. "Ageing, as a process, is irreversible. While it can't be stopped, it can be slowed down." According to the research, travelling, exploring new corners of the world and engaging in unique and relaxing activities can stimulate stress responses and elevate metabolic rates, positively influencing metabolic activities and the body's self-organising capabilities. "Leisurely travel activities might help alleviate chronic stress, dampen over-activation of the immune system, and encourage normal functioning of the self-defence system," Fangli added. While some people prefer relaxing holidays, others prefer to stay on their feet and keep active during their travels, enjoying the many well-known benefits of exercise. It can "enhance the body's immune function and self-defence capabilities, bolstering its hardiness to external risks". In response to their study, the experts suggested that "travel therapy could serve as a groundbreaking health intervention." Despite the positive results of the research, experts also warned that travelling can exposed to infectious diseases, accidents, injuries, violence, water and food safety issues, and concerns related to inappropriate tourism engagement, which in turn will have the opposite effect on our health. "Conversely, tourism can involve negative experiences that potentially lead to health problems, paralleling the process of promoting entropy increase," Fangli said. Image credits: Shutterstock

The internet is worse than it used to be. How did we get here, and can we go back?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/marc-cheong-998488">Marc Cheong</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> and <a href="https://theconversation.com/profiles/wonsun-shin-1300054">Wonsun Shin</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> When it comes to our experience of the internet, “the times, <a href="https://en.wikipedia.org/wiki/The_Times_They_Are_a-Changin%27_(song)">they are a-changin’</a>”, as Bob Dylan would say. You can’t quite recall how, but the internet certainly feels different these days. To some, it is “<a href="https://www.npr.org/2024/01/16/1224878097/everyday-users-are-complaining-that-the-internet-is-more-chaotic-than-ever">less fun and less informative</a>” than it used to be. To others, online searches are made up of “<a href="https://www.theverge.com/c/23998379/google-search-seo-algorithm-webpage-optimization?src=longreads">cookie cutter</a>” pages that drown out useful information and are saturated with scams, spam and content generated by artificial intelligence (AI). Your social media feeds are full of eye-catching, provocative, hyper-targeted, or anger-inducing content, from <a href="https://theconversation.com/the-dead-internet-theory-makes-eerie-claims-about-an-ai-run-web-the-truth-is-more-sinister-229609">bizarre AI-generated imagery</a> to robot-like comments. You’re lucky if your video feeds are not solely made up of exhortations to “subscribe”. How did we get here? And can we claw our way back? <h2>Commercial interests rule</h2> One major factor contributing to the current state of the internet is its over-commercialisation: financial motives drive much of the content. This has arguably led to the prevalence of sensationalism, prioritising virality over information quality. Covert and deceptive advertising is widespread, blurring the line between commercial and non-commercial content to attract more attention and engagement. Another driving force is the dominance of tech giants like Google, Meta and Amazon. They reach billions worldwide and wield immense power over the content we consume. Their platforms use advanced tracking technologies and opaque algorithms to generate hyper-targeted media content, powered by extensive user data. This creates <a href="https://www.campaignasia.com/article/the-echo-chamber-effect-how-algorithms-shape-our-worldview/491762">filter bubbles</a>, where users are exposed to limited content that reinforces their existing beliefs and biases, and <a href="https://philarchive.org/archive/NGUECA">echo chambers</a> where other viewpoints are actively discredited. Bad actors like <a href="https://abcnews.go.com/Technology/ai-fuel-financial-scams-online-industry-experts/story?id=103732051">cyber criminals and scammers</a> have been an enduring problem online. However, evolving technology like generative AI has further empowered them, enabling them to create highly realistic fake images, deepfake videos and <a href="https://www.newyorker.com/science/annals-of-artificial-intelligence/the-terrifying-ai-scam-that-uses-your-loved-ones-voice">voice cloning</a>. AI’s ability to automate content creation has also flooded the internet with low-quality, misleading and harmful material at an unprecedented scale. In sum, the accelerated commercialisation of the internet, the dominance of media tech giants and the presence of bad actors have infiltrated content on the internet. The rise of AI further intensifies this, making the internet more chaotic than ever. <h2>Some of the ‘good’ internet remains</h2> So, what was the “good internet” some of us long for with nostalgia? At the outset, the internet was meant to be a free egalitarian space people were meant to “surf” and “browse”. Knowledge was meant to be shared: sites such as Wikipedia and The Internet Archive are continuing bastions of knowledge. Before the advent of filter bubbles, the internet was a creative playground where people explored different ideas, discussed varying perspectives, and collaborated with individuals from “outgroups” – those outside their social circles who may hold opposing views. Early social media platforms were built on the ethos of reconnecting with long-lost classmates and family members. Many of us have community groups, acquaintances and family we reach out to via the internet. The “connection” aspect of the internet remains as important as ever – as we all saw during the COVID pandemic. What else do we want to preserve? Privacy. A New Yorker cartoon joke in 1993 stated that “<a href="https://web.archive.org/web/20051029045942/http://www.unc.edu/depts/jomc/academics/dri/idog.html">on the internet, nobody knows you’re a dog</a>”. Now everyone – especially advertisers – wants to know who you are. To quote the <a href="https://www.oaic.gov.au/privacy/your-privacy-rights/your-personal-information/what-is-privacy">Office of the Australian Information Commissioner</a>, one of the tenets of privacy is “to be able to control who can see or use information about you”. At the very least, we want to control what big tech knows about us, especially if they could stand to profit from it. <h2>Can we ever go back?</h2> We can’t control “a changin’” times, but we can keep as much of the good parts as we can. For starters, we can vote with our feet. Users can enact change and bring awareness to problems on existing platforms. In recent times, we have seen this with the <a href="https://theconversation.com/thinking-of-breaking-up-with-twitter-heres-the-right-way-to-do-it-195002">exodus of users</a> from X (formerly Twitter) to other platforms, and the <a href="https://www.economist.com/the-economist-explains/2023/06/26/why-reddit-users-are-protesting-against-the-sites-leadership">platform-wide protest against Reddit</a> for changing its third-party data access policies. However, voting with our feet is only possible when there’s competition. In the case of X, various other platforms – from Mastodon to Threads to Bluesky – enable users to pick one that aligns with their preferences, values and social circles. Search engines have alternatives, too, such as DuckDuckGo or Ecosia. But competition can only be created by moving to decentralised systems and removing monopolies. This actually happened in the early days of the internet during the 1990s “<a href="https://thehistoryoftheweb.com/browser-wars/">browser wars</a>”, when Microsoft was eventually accused of illegally monopolising the web browser market in <a href="https://en.wikipedia.org/wiki/United_States_v._Microsoft_Corp.">a landmark court case</a>. As users of technology, all of us must remain vigilant about threats to our privacy and knowledge. With cheap and ubiquitous generative AI, misleading content and scams are more realistic as ever. We must exercise healthy scepticism and ensure those most at risk from online threats – such as children and older people – are educated about potential harms. Remember, the internet is not optimised for your best interests. It’s up to you to decide how much power you give to the tech giants who are fuelling theirs.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/236513/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/marc-cheong-998488">Marc Cheong</a>, Senior Lecturer of Information Systems, School of Computing and Information Systems; and (Honorary) Senior Fellow, Melbourne Law School, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> and <a href="https://theconversation.com/profiles/wonsun-shin-1300054">Wonsun Shin</a>, Associate Professor in Media and Communications, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Your gas stove might be making your asthma worse. Here’s what you can do about it

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/nusrat-homaira-1199433">Nusrat Homaira</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> We may think of air pollution as an outdoor problem, made up of car exhaust and smog. But if the air inside our homes is polluted, this can also affect our health. In Australia, around 12% of childhood asthma can <a href="https://pubmed.ncbi.nlm.nih.gov/29642816/">be attributed</a> to gas stoves and the toxic chemicals they release into the air. And while there’s a growing push to phase out gas indoors, some 38% of Australian households <a href="https://www.mja.com.au/journal/2018/208/7/damp-housing-gas-stoves-and-burden-childhood-asthma-australia">rely on natural gas</a> for cooking. Recommended interventions – such as replacing a gas stove with electric – may not be possible for those who are renting or struggling with the cost of living. This is important because, as our <a href="https://ghrp.biomedcentral.com/articles/10.1186/s41256-024-00361-2">research</a> shows, childhood asthma is more common in socioeconomically disadvantaged areas. If you’re living with gas, here’s how it can affect you or your child’s asthma, and what you can do to improve air quality. <h2>What is asthma?</h2> Asthma is the most common chronic condition in Australian children. The respiratory condition affects <a href="https://www.aihw.gov.au/reports/chronic-respiratory-conditions/asthma">almost</a> 400,000 of those aged aged 14 and under – close to 9% of that age group. Asthma narrows the airways and obstructs airflow, making it hard to breath. Many people manage the condition with inhalers and <a href="https://asthma.org.au/manage-asthma/asthma-action-plan/">asthma action plans</a>. But it can be serious and even fatal. Australian emergency departments saw <a href="https://www.aihw.gov.au/reports/chronic-respiratory-conditions/asthma">56,600 presentations</a> for asthma in 2020-21. While there is no single cause for asthma, both indoor and outdoor air pollution play a <a href="https://pubmed.ncbi.nlm.nih.gov/38247719/">significant role</a>. Being exposed to small <a href="https://aafa.org/asthma/asthma-triggers-causes/air-pollution-smog-asthma/#:%7E:text=Air%20pollution%20can%20increase%20your,if%20you%20already%20have%20asthma.&text=Small%20airborne%20particles%2C%20found%20in,%E2%80%9Cparticulate%20matter%E2%80%9D%20or%20PM.">airborne particles</a> increases your risk of getting asthma, and can aggravate symptoms if you already have it. <h2>Gas stoves release nitrogen dioxide</h2> The gas stoves commonly found in Australian homes release toxic chemicals into the air. They include carbon monoxide (CO), PM₂.₅ (small particles, often from <a href="https://www.epa.vic.gov.au/for-community/environmental-information/air-quality/pm25-particles-in-the-air">smoke</a>), benzene, formaldehyde and nitrogen dioxide (NO₂). All are harmful, but nitrogen dioxide in particular is <a href="https://go.gale.com/ps/i.do?id=GALE%7CA656312383&sid=googleScholar&v=2.1&it=r&linkaccess=abs&issn=00220892&p=AONE&sw=w&userGroupName=anon%7E7027bb9f&aty=open-web-entry">associated</a> with asthma developing and getting <a href="https://www.atsjournals.org/doi/10.1164/rccm.200408-1123OC">worse</a>. Gas heaters can also <a href="https://pubmed.ncbi.nlm.nih.gov/9731022/">produce</a> nitrogen dioxide. As nitrogen dioxide is a tasteless, invisible gas, it’s difficult to know how much is in your air at home unless you have an air monitor. However one US <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2662932/">study</a> showed houses with gas stoves can have nitrogen dioxide levels three times higher than houses with electric stoves. This is particularly concerning for households with children, given children tend to spend <a href="https://pubmed.ncbi.nlm.nih.gov/11477521/">most</a> of their time indoors. <h2>Banning gas</h2> There is a growing push across Australia to replace gas stoves with electric stoves, which are more energy efficient and can reduce indoor air pollution. <a href="https://www.premier.vic.gov.au/new-victorian-homes-go-all-electric-2024">Victoria</a> and the <a href="https://www.climatechoices.act.gov.au/energy/canberras-electrification-pathway/preventing-new-gas-network-connections">Australian Capital Territory</a> have announced bans on gas connections in new homes from 2024. Sydney’s Waverley council recently made a similar <a href="https://www.waverley.nsw.gov.au/environment/climate_resilience_and_reducing_emissions/go_electric">move</a>. But until a ban on using household gas appliances is implemented across the country, the problem persists for children who are currently living in old homes or rented properties with gas stoves. <h2>Do exhaust fans in the kitchen help?</h2> Using a high-efficiency <a href="https://pubmed.ncbi.nlm.nih.gov/24750219/">exhaust hood</a> placed over an existing gas cooktop can be effective. They can <a href="https://www.mja.com.au/journal/2018/208/7/damp-housing-gas-stoves-and-burden-childhood-asthma-australia">capture</a> more than 75% of air pollutants and direct them outside. Cooking on the back burner – rather than the front burner – can also <a href="https://pubmed.ncbi.nlm.nih.gov/24750219/">improve their efficiency</a>. However exhaust hoods with lower flow rates, or hoods that don’t vent the air outside, are less effective. And an exhaust hood only improves air quality if you use it. One <a href="https://pubmed.ncbi.nlm.nih.gov/10520075/">study</a> in Melbourne found more than 40% of people didn’t use an exhaust hood regularly while cooking. For many people, installing high-efficiency exhaust hoods will not be practical – especially for those renting or experiencing socio-economic disadvantage. <h2>Natural ventilation</h2> There is a free way to ventilate your home. Keeping windows open during and after cooking will increase air flow and <a href="https://pubmed.ncbi.nlm.nih.gov/32970538/">evidence shows</a> this can improve overall air quality. However this is not always possible, especially during cooler months of the year which can be especially chilly in places such as Victoria and Tasmania. Unfortunately, people are also more likely to use gas heaters during those cooler months. <h2>What about heaters?</h2> There are two kinds of gas heaters, flued and unflued. Like cooking with gas, unflued gas heaters release air pollutants including nitrogen dioxide directly into the home. Flued heaters are better for air quality because they use a chimney, or “flue”, to send emissions outside. If you can, replacing your unflued gas heater with a flued one – or even better, an electric heater – can significantly <a href="https://pubmed.ncbi.nlm.nih.gov/15075170/">alleviate</a> asthma symptoms. If you can’t replace your unflued gas heater, <a href="https://www.health.nsw.gov.au/environment/factsheets/Pages/unflued-gas-heaters.aspx">do not use it overnight</a> in the room where you or your children sleep. Asthma can’t be cured, but its symptoms can be controlled by managing triggers – and this may be easier to do indoors than out. Improving air quality, even in a rented or old property, can help people with asthma breathe more easily.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/238787/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/nusrat-homaira-1199433">Nusrat Homaira</a>, Senior Lecturer, School of Clinical Medicine, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

What causes food cravings? And what can we do about them?

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/gabrielle-weidemann-91497">Gabrielle Weidemann</a>, <a href="https://theconversation.com/institutions/western-sydney-university-1092">Western Sydney University</a> and <a href="https://theconversation.com/profiles/justin-mahlberg-1634725">Justin Mahlberg</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> Many of us try to eat more fruits and vegetables and less ultra-processed food. But why is sticking to your goals so hard? High-fat, sugar-rich and salty foods are simply so enjoyable to eat. And it’s not just you – we’ve evolved that way. These foods <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5928395/">activate</a> the brain’s reward system because in the past they were <a href="https://doi.org/10.1037/a0030684">rare</a>. Now, they’re all around us. In wealthy modern societies we are bombarded by <a href="https://theconversation.com/junk-food-is-promoted-online-to-appeal-to-kids-and-target-young-men-our-study-shows-234285">advertising</a> which intentionally reminds us about the sight, smell and taste of calorie-dense foods. And in response to these powerful cues, our brains respond just as they’re designed to, triggering <a href="https://doi.org/10.1111/obr.12354">an intense urge</a> to eat them. Here’s how food cravings work and what you can do if you find yourself hunting for sweet or salty foods. <h2>What causes cravings?</h2> A food craving is an intense desire or urge to eat something, <a href="https://pubmed.ncbi.nlm.nih.gov/15589112/">often focused on a particular food</a>. We are programmed to learn how good a food tastes and smells and where we can find it again, especially if it’s high in fat, sugar or salt. Something that <a href="https://doi.org/10.1111/obr.12354">reminds us</a> of enjoying a certain food, such as an eye-catching ad or delicious smell, can cause us to <a href="https://doi.org/10.1111/obr.12354">crave it</a>. The cue triggers a physical response, increasing saliva production and gastric activity. These responses are relatively automatic and difficult to control. <h2>What else influences our choices?</h2> While the effect of cues on our physical response is relatively automatic, what we do next is influenced by <a href="https://journals.sagepub.com/doi/pdf/10.1177/1090198107303308">complex</a> factors. Whether or not you eat the food might depend on things like cost, whether it’s easily available, and if eating it would align with your health goals. But it’s usually hard to keep healthy eating in mind. This is because we tend to prioritise a more immediate reward, like the <a href="https://doi.org/10.1016/j.physbeh.2010.04.029">pleasure of eating</a>, over one that’s delayed or abstract – including health goals that will make us feel good in the long term. <a href="https://doi.org/10.1016/S0022-3999(00)00076-3">Stress</a> can also make us eat more. When hungry, we <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8656885/">choose larger portions</a>, underestimate calories and find eating more <a href="https://www.sciencedirect.com/science/article/pii/S0195666315000793">rewarding</a>. <h2>Looking for something salty or sweet</h2> So what if a cue prompts us to look for a certain food, but it’s not available? <a href="https://doi.org/10.1016/j.appet.2014.04.005">Previous research</a> suggested you would then look for anything that makes you feel good. So if you saw someone eating a doughnut but there were none around, you might eat chips or even drink alcohol. But our <a href="https://doi.org/10.1016/j.appet.2024.107640">new research</a> has confirmed something you probably knew: it’s more specific than that. If an ad for chips makes you look for food, it’s likely a slice of cake won’t cut it – you’ll be looking for something salty. Cues in our environment don’t just make us crave food generally, they prompt us to look for certain food “categories”, such as salty, sweet or creamy. <h2>Food cues and mindless eating</h2> Your <a href="https://core.ac.uk/download/pdf/161283824.pdf">eating history</a> and <a href="https://doi.org/10.1002/eat.24179">genetics</a> can also make it harder to suppress food cravings. But don’t beat yourself up – relying on willpower alone is <a href="https://doi.org/10.1016/j.appet.2015.01.004">hard</a> for almost everyone. Food cues are so powerful they can prompt us to <a href="https://doi.org/10.1177/0956797613484043">seek</a> out a certain food, even if we’re not overcome by a particularly <a href="https://doi.org/10.1177/0956797613484043">strong urge</a> to eat it. The effect is more intense if the food is easily available. This helps explain why we can eat an entire large bag of chips that’s in front of us, even though our pleasure decreases as we <a href="https://doi.org/10.1016/0031-9384(81)90310-3">eat</a>. Sometimes we use finishing the packet as the signal to stop <a href="https://doi.org/10.1016/j.physbeh.2015.03.025">eating</a> rather than hunger or desire. <h2>Is there anything I can do to resist cravings?</h2> We largely don’t have control over cues in our environment and the cravings they trigger. But there are some ways you can try and control the situations you make food choices in. <ul> <li> Acknowledge your craving and think about a healthier way to satisfy it. For example, if you’re craving chips, could you have lightly-salted nuts instead? If you want something sweet, you could try fruit. </li> <li> Avoid shopping when you’re hungry, and make a list beforehand. Making the most of supermarket “click and collect” or delivery options can also help avoid ads and impulse buys in the aisle. </li> <li> At home, have fruit and vegetables easily available – and easy to see. Also have other nutrient dense, fibre-rich and unprocessed foods on hand such as nuts or plain yoghurt. If you can, remove high-fat, sugar-rich and salty foods from your environment. </li> <li> Make sure your goals for eating are <a href="https://www.aafp.org/pubs/fpm/issues/2018/0300/p31.html">SMART</a>. This means they are specific, measurable, achievable, relevant and time-bound. </li> <li> Be kind to yourself. Don’t beat yourself up if you eat something that doesn’t meet your health goals. Just keep on trying.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/237035/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> </li> </ul> <a href="https://theconversation.com/profiles/gabrielle-weidemann-91497">Gabrielle Weidemann</a>, Associate Professor in Psychological Science, <a href="https://theconversation.com/institutions/western-sydney-university-1092">Western Sydney University</a> and <a href="https://theconversation.com/profiles/justin-mahlberg-1634725">Justin Mahlberg</a>, Research Fellow, Pyschology, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Food & Wine

Retirement doesn’t just raise financial concerns – it can also mean feeling unmoored and irrelevant

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/marianne-janack-681018">Marianne Janack</a>, <a href="https://theconversation.com/institutions/hamilton-college-2966">Hamilton College</a> Most discussions of retirement focus on the financial aspects of leaving the workforce: “<a href="https://www.dol.gov/sites/dolgov/files/EBSA/about-ebsa/our-activities/resource-center/publications/top-10-ways-to-prepare-for-retirement.pdf">How to save enough for retirement</a>” or “<a href="https://www.businessinsider.com/personal-finance/investing/when-can-i-retire">How do you know if you have enough money for retirement</a>?” But this might not be the biggest problem that potential retirees face. The deeper issues of meaning, relevance and identity that retirement can bring to the fore are more significant to some workers. Work has <a href="https://www.theatlantic.com/ideas/archive/2023/03/work-revolution-ai-wfh-new-book/673572/">become central to the modern American identity</a>, as <a href="https://www.theatlantic.com/atlantic-editions/">journalist Derek Thompson bemoans</a> in The Atlantic. And some theorists have argued that work shapes what we are. For most people, as business ethicist <a href="https://www.luc.edu/quinlan/faculty/algini.shtml#:%7E:text=About,the%20Society%20for%20Business%20Ethics.">Al Gini</a> argues, one’s work – which is usually also one’s job – <a href="https://doi.org/10.4324/9780203950555">means more than a paycheck</a>. Work can structure our friendships, our understandings of ourselves and others, our ideas about free time, our forms of entertainment – indeed our lives. I <a href="https://www.hamilton.edu/academics/our-faculty/directory/faculty-detail/marianne-janack">teach a philosophy course about the self</a>, and I find that most of my students think of the problems of identity without thinking about how a job will make them into a particular kind of person. They think mostly about the prestige and pay that come with certain jobs, or about where jobs are located. But when we get to <a href="https://plato.stanford.edu/entries/existentialism/">existentialist philosophers</a> such as <a href="https://plato.stanford.edu/entries/sartre/">Jean-Paul Sartre</a> and <a href="https://plato.stanford.edu/entries/beauvoir/">Simone de Beauvoir</a>, I often urge them to think about what it means to say, as the existentialists do, <a href="https://philosophynow.org/issues/115/On_Being_An_Existentialist">that “you are what you do</a>.” How you spend 40 years of your life, I tell them, for at least 40 hours each week – the time many people spend at their jobs – is not just a financial decision. And I have come to see that retirement isn’t just a financial decision, either, as I consider that next phase of my life. <h2>Usefulness, tools and freedom</h2> For Greek and Roman philosophers, <a href="https://search.worldcat.org/title/Work-what-it-has-meant-to-men-through-the-ages/oclc/780872063">leisure was more noble than work</a>. The life of the craftsperson, artisan – or even that of the university professor or the lawyer – was to be avoided if wealth made that possible. The good life was a life not driven by the necessity of producing goods or making money. Work, Aristotle thought, was an obstacle to the achievement of the particular forms of excellence characteristic of human life, like thought, contemplation and study – <a href="https://classics.mit.edu/Aristotle/nicomachaen.7.vii.html">activities that express</a> the <a href="https://classics.mit.edu/Aristotle/nicomachaen.8.viii.html">particular character of human beings</a> and are done for their own sake. And so, one might surmise, retirement would be something that would allow people the kind of leisure that is essential to human excellence. But contemporary retirement does not seem to encourage leisure devoted to developing human excellence, partly because it follows a long period of making oneself into an object – something that is not free. German philosopher Immanuel Kant distinguished between the value of objects and of subjects by the idea of “use.” Objects are not free: They are meant to be used, like tools – their value is tied to their usefulness. But rational beings like humans, who are subjects, are more than their use value – <a href="https://search.worldcat.org/title/5796114">they are valuable in their own right</a>, unlike tools. And yet, much of contemporary work culture encourages workers to think of themselves and their value <a href="https://www.simonandschuster.com/books/Bullshit-Jobs/David-Graeber/9781501143335">in terms of their use value</a>, a change that would have made both Kant and the ancient Greek and Roman philosophers wonder why people didn’t retire as soon as they could. <h2>‘What we do is what we are’</h2> But as one of my colleagues said when I asked him about retirement: “If I’m not a college professor, then what am I?” Another friend, who retired at 59, told me that she does not like to describe herself as retired, even though she is. “Retired implies useless,” she said. So retiring is not just giving up a way of making money; it is a deeply existential issue, one that challenges one’s idea of oneself, one’s place in the world, and one’s usefulness. One might want to say, with Kant and the ancients, that those of us who have tangled up our identities with our jobs have made ourselves into tools, and we should throw off our shackles by retiring as soon as possible. And perhaps from the outside perspective, that’s true. But from the participant perspective, it’s harder to resist the ways in which what we have done has made us what we are. Rather than worry about our finances, we should worry, as we think about retirement, more about what the good life for creatures like us – those who are now free from our jobs – should be.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/233963/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/marianne-janack-681018">Marianne Janack</a>, John Stewart Kennedy Professor of Philosophy, <a href="https://theconversation.com/institutions/hamilton-college-2966">Hamilton College</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Retirement Income

What’s a recession – and how can we tell if we’re in one?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/leonora-risse-405312">Leonora Risse</a>, <a href="https://theconversation.com/institutions/university-of-canberra-865">University of Canberra</a> Today’s <a href="https://www.abs.gov.au/statistics/economy/national-accounts/australian-national-accounts-national-income-expenditure-and-product/latest-release">economic data</a> shows that, outside of the pandemic, the Australian economy has slowed down to its lowest annual rate of growth since the early-1990s recession. That’s prompting the dreaded question: are we headed for another one? Any mention of the “R” word can trigger anxiety. Recessions bring job losses and financial strain, and put serious pressure on people’s mental health. These impacts can be especially severe for people who are already experiencing disadvantage and vulnerabilities. But what exactly does it mean to be in a recession? What are the different ways we define them? And are these current approaches the best way to measure people’s economic pain? <h2>What’s a recession?</h2> A bit like the waves of the ocean, our economy is characterised by ebbs and flows in overall activity. Spending and business growth can swell during times of confidence, but slow down when optimism deflates or the economy is hit by an unexpected shock such as a pandemic or climate disaster. This pattern is what economists describe as “the business cycle”. Most of the time, our economy is constantly growing, even if the pace varies. Conventionally, we measure this pace by tracking changes in the level of <a href="https://www.rba.gov.au/education/resources/explainers/economic-growth.html">gross domestic product</a> (GDP) – the overall volume of items and services being produced, bought and sold in the economy. The <a href="https://www.abs.gov.au/statistics/economy/national-accounts/australian-national-accounts-national-income-expenditure-and-product/jun-2024">latest economic growth rates</a> of 0.2% for the June quarter, and 1% over the past year, tell us that the Australian economy is still growing, even if at a slower pace than previous years. Occasionally, the economy slows down to such a grind that economic activity, from one quarter to the next, shrinks. When this happens, the GDP measurements come out negative. When we have two negative measurements of GDP in a row, this is defined as a <a href="https://www.rba.gov.au/education/resources/explainers/recession.html">technical recession</a>. This is what happened to most countries around the globe during the COVID-19 pandemic. Prior to the pandemic, Australia hadn’t experienced a technical recession since 1991. The latest figures tell us Australia is staying afloat for now. But that doesn’t mean it doesn’t feel like a recession to many people. Some other metrics show why. <h2>Other measures of recession</h2> Growth in economic activity is fuelled, in part, by a growing population. Dividing total economic output by the population size, GDP per capita can offer a more accurate picture of people’s economic reality. This population-adjusted measure of economic growth has long fallen into negative territory. Today’s figures tell us that Australia’s GDP per person has been shrinking for 18 months. Our annual per capita growth rate is now -1.5%. <figure class="align-right zoomable"></figure> In the United States, recessions are measured differently again. Recessions are officially declared by the National Bureau of Economic Research (<a href="https://www.nber.org/research/business-cycle-dating">NBER</a>). Unlike technical recessions, these aren’t based on a simple rule. NBER considers a range of measures beyond GDP – including personal income, employment, personal consumption, wholesale and retail sales, and industrial production across multiple sectors – when deciding whether to declare a US recession. <h2>Is Australia heading for a recession?</h2> This is a challenging question to answer because the GDP figures economists conventionally use to diagnose the situation only come to light after a recession hits. Today’s economic figures from the ABS are for the June 2024 quarter – now more than two months old. Measurements of the current economic climate won’t come through in official statistics for some time. If it occurs, by the time a recession is officially diagnosed, we’re usually well and truly in it. A similar limitation applies to the retrospective approach of the <a href="https://www.nber.org/research/business-cycle-dating">NBER</a>, which “waits until it is confident that a recession has occurred”. It’s like a weather forecaster declaring a cyclone has hit only after the wind gusts have blown your roof away. But we can use other metrics to alert ourselves to recession risks before the eye of the storm hits. <h2>Using jobs numbers as a recession alert</h2> One approach is the <a href="https://fred.stlouisfed.org/series/SAHMCURRENT">Sahm Rule</a>, named after its creator, US economist Claudia Sahm. By analysing patterns in the monthly unemployment data that preceded past recessions, Sahm devised a <a href="https://stayathomemacro.substack.com/p/the-sahm-rule-step-by-step">formula</a> to detect when increases in the current unemployment rate were rapid enough to pose a recession risk. The advantage of this approach is that unemployment statistics come out more quickly and frequently than GDP numbers. Many would also argue that monitoring unemployment, rather than GDP, is a more meaningful metric to reflect people’s everyday experiences of the economy and wellbeing. The Sahm approach tracks how quickly the national unemployment rate is currently rising compared to the past year. It’s calculated by comparing the current three-month moving average of the national unemployment rate to this figure’s lowest value in the previous 12 months. This “moving average” approach smooths out the bumpiness of monthly figures. A jump of 0.5% or more signals the economy’s current pattern is on the cusp of recession. While the Sahm formula was developed for the US economy, it does a fairly good job of waving a red flag where recessions previously occurred in the Australian economy, too. Australia’s latest unemployment rate – inching up to 4.2% in July 2024 – pushed the Sahm value up to 0.5%. <iframe id="3d239" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/3d239/5/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe> This indicator doesn’t necessarily mean that a recession will occur. But it suggests policymakers should be on high alert. The Sahm indicator also validates the experiences of job seekers who – despite official definitions that the economy is not in recession – are personally feeling the pressures of a slowing economy and shrinking job opportunities. As our approaches to measuring and managing the ups and downs of the economy continue to evolve, these people-centred metrics are an increasingly important part of our toolkit.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/238199/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/leonora-risse-405312">Leonora Risse</a>, Associate Professor in Economics, <a href="https://theconversation.com/institutions/university-of-canberra-865">University of Canberra</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.
