The latest COVID booster will soon be available. Should I get one? Am I eligible?

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/nathan-bartlett-1198187">Nathan Bartlett</a>, <a href="https://theconversation.com/institutions/university-of-newcastle-1060">University of Newcastle</a></em></p> <p>Australia’s <a href="https://www.tga.gov.au/products/covid-19/covid-19-vaccines/covid-19-vaccines-regulatory-status">Therapeutic Goods Administration</a> (TGA) has recently approved a new COVID booster. The shot was developed by Pfizer and targets <a href="https://www.sbs.com.au/news/article/what-to-know-about-the-new-covid-19-vaccine-approved-in-australia/z7ev2u8qn">the JN.1 sub-variant</a> of Omicron.</p> <p>This is now <a href="https://theconversation.com/new-covid-vaccines-may-be-coming-to-australia-heres-what-to-know-about-the-jn-1-shots-237652">the fifth iteration</a> of the COVID vaccines, which have been updated regularly to keep up with the rapidly evolving virus, SARS-CoV-2.</p> <p>But nearly five years into the pandemic, you may be wondering, why do we need yet another type of COVID booster? And do we still need to be getting boosters at all? Here’s what to consider.</p> <h2>Targeting the spike protein</h2> <p>Pfizer’s JN.1 booster (and Moderna’s, though the TGA has <a href="https://www.tga.gov.au/products/covid-19/covid-19-vaccines/covid-19-vaccines-regulatory-status">not approved</a> this one at this stage) is based on mRNA technology. This technology instructs our cells to produce a specific protein – in this case SARS-CoV-2’s spike, a protein on the surface of the virus that allows it to attach to our cells.</p> <p>This helps the immune system produce antibodies that recognise the spike protein and interfere with the virus getting into our cells.</p> <p>In response to our strengthened immune responses from vaccinations and previous infections (called immune pressure), SARS-CoV-2 has continued to evolve over the course of the pandemic, modifying the shape of its spike protein so our antibodies become less effective.</p> <p>Most recently we’ve faced a soup of Omicron sub-variants, including JN.1. Since JN.1 was first detected <a href="https://www.gavi.org/vaccineswork/seven-things-you-need-know-about-jn1-covid-19-variant">in August 2023</a>, this Omicron sub-variant has spawned a variety of further sub-variants, such as KP.2 (known as FLiRT), KP.3 (<a href="https://theconversation.com/from-flirt-to-fluqe-what-to-know-about-the-latest-covid-variants-on-the-rise-234073">known as FLuQE</a>) and <a href="https://theconversation.com/xec-is-now-in-australia-heres-what-we-know-about-this-hybrid-covid-variant-239292">XEC</a>.</p> <p>The spike protein is made up of <a href="https://www.nature.com/articles/s41401-020-0485-4">1,273 amino acids</a>, a bit like molecular building blocks. Mutations to <a href="https://www.frontiersin.org/journals/microbiology/articles/10.3389/fmicb.2023.1228128/full">the spike protein</a> change individual amino acids.</p> <p>Certain amino acids are important for allowing neutralising antibodies to bind to the spike protein. This means changes can give the virus an edge over earlier variants, helping it evade our immune response.</p> <p>Scientists keep updating the COVID vaccines in an effort to keep up with these changes. The better matched the vaccine “spike” is to the spike protein on the surface of the virus trying to infect you, the better protection you’re likely to get.</p> <h2>So who should get vaccinated, and when?</h2> <p>Updating vaccines to deal with mutating viruses is not a new concept. It has been happening for the flu vaccine since <a href="https://www.who.int/news-room/spotlight/history-of-vaccination/history-of-influenza-vaccination">around 1950</a>.</p> <p>We’ve become accustomed to getting the annual flu vaccine in the lead-up to the winter cold and flu season. But, unlike influenza, COVID has not settled into this annual seasonal cycle. The frequency of COVID waves of infection has been fluctuating, with new waves emerging periodically.</p> <p>COVID is also <a href="https://academic.oup.com/jtm/article/29/8/taac108/6731971">more transmissible</a> than the flu, which presents another challenge. While numbers vary, a conservative estimate of the reproduction number (R0 – how many people will one person will go on to infect) for JN.1 is 5. Compare this to seasonal flu with an R0 of <a href="https://bmcinfectdis.biomedcentral.com/articles/10.1186/1471-2334-14-480">about 1.3</a>. In other words, COVID could be four times more transmissible than flu.</p> <p>Add to this immunity from a COVID vaccination (or a previous infection) <a href="https://www.nature.com/articles/d41586-023-00124-y">begins to wane</a> in the months afterwards.</p> <p>So an annual COVID booster is not considered enough for some more vulnerable people.</p> <p><iframe id="gOYwk" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/gOYwk/2/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe></p> <p>For adults <a href="https://www.health.gov.au/our-work/covid-19-vaccines/getting-your-vaccination">aged 65 to 74</a>, a booster is recommended every 12 months, but they’re eligible every six months. For adults over 75, a shot is recommended every six months.</p> <p>Adults aged 18 to 64 are eligible every 12 months, unless they have a severe immune deficiency. Many conditions can cause immunodeficiency, including genetic disorders, infections, cancer, autoimmune diseases, diabetes and lung disease, as well as having received an organ transplant. For this group, it’s recommended they receive a shot every 12 months, but they’re eligible every six.</p> <h2>Making sense of the advice</h2> <p>A vaccine that targets JN.1 should provide good protection against the Omicron sub-variants likely to be circulating in the coming months.</p> <p>A few things need to happen before the JN.1 shots become available, such as the Australian Technical Advisory Group on Immunisation providing guidance to the government. But we can reasonably expect they might be rolled out <a href="https://www.sbs.com.au/news/article/what-to-know-about-the-new-covid-19-vaccine-approved-in-australia/z7ev2u8qn">within the next month or so</a>.</p> <p>If they hit doctors’ offices and pharmacies before Christmas and you’re due for a booster, the holiday period might be added impetus to go and get one, especially if you’re planning to attend lots of family and social gatherings over summer.</p> <p>In the meantime, the <a href="https://theconversation.com/what-are-the-new-covid-booster-vaccines-can-i-get-one-do-they-work-are-they-safe-217804">XBB.1.5 vaccines</a> remain available. Although they’re targeted at an earlier Omicron sub-variant, they should still offer some protection.</p> <p>While young, healthy people might like to wait for the updated boosters, for those who are vulnerable and due for a vaccination, whether or not to hold out may be something to weigh up with your doctor.</p> <p>The advice on COVID boosters in Australia, with stronger wording (“recommended” versus “eligible”) used for more vulnerable groups, reflects what we know about COVID. People <a href="https://academic.oup.com/ageing/article/49/6/901/5862042">who are older</a> and medically vulnerable are more likely to become very unwell with the virus.</p> <p>For young, healthy people who may be wondering, “do I need a COVID booster at all?”, having one annually is sensible. Although you’re less likely to get very sick from COVID, it’s possible. And, importantly, vaccines also reduce the risk of <a href="https://www.thelancet.com/journals/lanres/article/PIIS2213-2600(24)00082-1/fulltext">developing long COVID</a>.</p> <p>While COVID vaccines do a very good job of protecting against severe disease, they don’t necessarily stop you becoming infected. Evidence on whether they reduce transmission <a href="https://www.nejm.org/doi/full/10.1056/NEJMoa2116597">has been mixed</a>, and <a href="https://pubmed.ncbi.nlm.nih.gov/38820077/">changed over time</a>.</p> <p>We’ve come to appreciate that vaccination is not going to free us of COVID. But it’s still our best defence against severe illness.<!-- Below is The Conversation's page counter tag.

How light can shift your mood and mental health

<div class="theconversation-article-body"><em><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></em></p> <p>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?</p> <p>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>.</p> <p>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.</p> <h2>An ancient rhythm of light and mood</h2> <p>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.</p> <p>“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.</p> <p>But how is this all linked with our mood and mental health?</p> <p>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.</p> <p>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).</p> <h2>Light on the brain</h2> <p>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>.</p> <p>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.</p> <p>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.</p> <h2>What happens when the seasons change?</h2> <p>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>”.</p> <p>What is less well known is that for other people, the change to spring and summer (when there is <em>more</em> 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.</p> <p>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.</p> <p>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.</p> <p>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.</p> <p>Alexis Hutcheon, who experiences seasonality and helped write this article, told us:</p> <blockquote> <p>[…] 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.</p> </blockquote> <h2>So what’s going on in the brain?</h2> <p>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.</p> <p>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>.</p> <p>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>.</p> <p>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.</p> <h2>How about bright light at night?</h2> <p>We know exposure to bright light at night (for instance, if someone is up all night) can disturb someone’s circadian rhythms.</p> <p>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).</p> <p>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>.</p> <p>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.</p> <h2>Where to from here?</h2> <p>Learning about light will help people better manage their mental health conditions.</p> <p>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.</p> <p>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.</p> <hr /> <p><em>Alexis Hutcheon has lived experience of a mental health condition and helped write this article.</em></p> <p><em>If this article has raised issues for you, or if you’re concerned about someone you know, call Lifeline on 13 11 14.</em><!-- Below is The Conversation's page counter tag.

COVID is surging in Australia – and only 1 in 5 older adults are up to date with their boosters

<p><em><a href="https://theconversation.com/profiles/adrian-esterman-1022994">Adrian Esterman</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em></p> <p>Do you have family members or friends sick with a respiratory infection? If so, there’s a good chance it’s COVID, caused by the JN.1 variant currently circulating in Australia.</p> <p>In particular, New South Wales is reportedly experiencing its <a href="https://www.abc.net.au/news/2024-01-09/nsw-sydney-covid-variant-virus-pandemic-hospitalisations/103298610">highest levels</a> of COVID infections in a year, while Victoria is said to be facing a “<a href="https://www.9news.com.au/national/victoria-in-midst-of-double-wave-of-covid19--as-jn1-triggers-infections-surge/4dada2cb-7d56-436a-9490-cad1d908a29a">double wave</a>” after a surge late last year.</p> <p>But nearly four years into the pandemic, data collection is less comprehensive than it was, and of course, fewer people are testing. So what do we know about the extent of this wave? And importantly, are we adequately protected?</p> <h2>Difficulties with data</h2> <p>Tracking COVID numbers was easier in the first half of last year, when each state and territory provided a weekly update, giving us data on case notifications, hospitalisations, ICU numbers and deaths.</p> <p>In the second half of the year some states and territories switched to less frequent reporting while others stopped their regular updates. As a result, different jurisdictions now report at different intervals and provide varying statistics.</p> <p>For example, <a href="https://www.health.vic.gov.au/infectious-diseases/victorian-covid-19-surveillance-report">Victoria</a> still provides weekly reports, while NSW publishes <a href="https://www.health.nsw.gov.au/Infectious/covid-19/Documents/respiratory-surveillance-20240106.pdf">fortnightly updates</a>.</p> <p>While each offer different metrics, we can gather – particularly from data on hospitalisations – that both states are experiencing a wave. We’re also seeing high levels of COVID <a href="https://www.health.vic.gov.au/infectious-diseases/victorian-covid-19-surveillance-report">in wastewater</a>.</p> <p>Meanwhile, <a href="https://health.nt.gov.au/covid-19/data">Northern Territory Health</a> simply tell you to go to the Australian government’s Department of Health website for COVID data. This houses the only national COVID <a href="https://www.health.gov.au/topics/covid-19/reporting?language=und">data collection</a>. Unfortunately, it’s not up to date, difficult to use, and, depending on the statistic, often provides no state and territory breakdowns.</p> <p>Actual case notifications are provided on a separate <a href="https://nindss.health.gov.au/pbi-dashboard/">website</a>, although given the lack of testing, these are likely to be highly inaccurate.</p> <p>The <a href="https://www.health.gov.au/topics/covid-19/reporting?language=und">Department of Health website</a> does provide some other data that gives us clues as to what’s happening. For example, as of one month ago, there were 317 active outbreaks of COVID in aged care homes. This figure has been generally rising since September.</p> <p>Monthly prescriptions for antivirals on the Pharmaceutical Benefits Scheme were increasing rapidly in November, but we are not given more recent data on this.</p> <p>It’s also difficult to obtain information about currently circulating strains. Data expert Mike Honey provides a regularly updated <a href="https://github.com/Mike-Honey/covid-19-genomes?tab=readme-ov-file#readme">snapshot</a> for Australia based on data from GISAID (the Global Initiative on Sharing All Influenza Data) that shows JN.1 rising in prevalence and accounting for about 40% of samples two weeks ago. The proportion is presumably higher now.</p> <h2>What’s happening elsewhere?</h2> <p>Many other countries are currently going through a COVID wave, probably driven to a large extent by JN.1. These include <a href="https://www.rnz.co.nz/news/national/506301/covid-19-complacency-waning-immunity-contribute-to-fifth-wave-epidemiologist">New Zealand</a>, <a href="https://www.independent.co.uk/news/world/europe/facemasks-mandatory-spain-hospitals-b2475563.html">Spain, Greece</a> and the United States.</p> <p>According to cardiologist and scientist Eric Topol, the US is currently experiencing its <a href="https://www.latimes.com/opinion/story/2024-01-04/covid-2024-flu-virus-vaccine">second biggest wave</a> since the start of the pandemic, linked to JN.1.</p> <h2>Are vaccines still effective?</h2> <p>It’s expected the current COVID vaccines, which target the omicron variant XBB.1.5, are still <a href="https://www.gavi.org/vaccineswork/seven-things-you-need-know-about-jn1-covid-19-variant">effective</a> at reducing hospitalisations and deaths from JN.1 (also an omicron offshoot).</p> <p>The Australian Technical Advisory Group on Immunisation (ATAGI) updated their <a href="https://www.health.gov.au/news/atagi-update-on-the-covid-19-vaccination-program">advice</a> on booster shots in September last year. They recommended adults aged over 75 should receive an additional COVID vaccine dose in 2023 if six months had passed since their last dose.</p> <p>They also suggest all adults aged 65 to 74 (plus adults of any age who are severely immunocompromised) should consider getting an updated booster. They say younger people or older adults who are not severely immunocompromised and have already had a dose in 2023 don’t need further doses.</p> <p>This advice is very confusing. For example, although ATAGI does not recommend additional booster shots for younger age groups, does this mean they’re not allowed to have one?</p> <p>In any case, as of <a href="https://www.health.gov.au/resources/publications/covid-19-vaccine-rollout-update-8-december-2023?language=en">December 6</a>, only 19% of people aged 65 and over had received a booster shot in the last six months. For those aged 75 and over, this figure is 23%. Where is the messaging to these at-risk groups explaining why updating their boosters is so important?</p> <h2>Should we be concerned by this wave?</h2> <p>That depends on who we mean by “we”. For those who are vulnerable, absolutely. Mainly because so few have received an updated booster shot and very few people, including the elderly, are wearing masks.</p> <p>For the majority of people, a COVID infection is unlikely to be serious. The biggest concern for younger people is the risk of long COVID, which research suggests <a href="https://www.nature.com/articles/s41591-022-02051-3">increases</a> with each reinfection.</p> <h2>What should we expect in 2024?</h2> <p>It’s highly likely we will see repeated waves of infections over the next 12 months and beyond, mainly caused by waning immunity from previous infection, vaccination or both, and new subvariants.</p> <p>Unless a new subvariant causes more severe disease (and at this stage, there’s no evidence JN.1 does), we should be able to manage quite well, without our hospitals becoming overwhelmed. However, we should be doing more to protect our vulnerable population. Having only one in five older people up to date with a booster and more than 300 outbreaks in aged care homes is not acceptable.</p> <p>For those who are vulnerable, the usual advice applies. Make sure you’re up to date with your booster shots, wear a P2/N95 mask when out and about, and if you do get infected, take antivirals as soon as possible.<!-- Below is The Conversation's page counter tag.

Are catnip and treats like it safe for cats? Here’s how they affect their minds and moods

<p><em><a href="https://theconversation.com/profiles/mia-cobb-15211">Mia Cobb</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> and <a href="https://theconversation.com/profiles/anne-quain-12802">Anne Quain</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>Cats kept indoors can <a href="https://safeandhappycats.com.au/">live a good life</a> when they get access to a variety of positive experiences. Examples include performing natural behaviours, feeling safe at home and using their full sensory capabilities, including their sense of smell.</p> <p>Plants such as catnip, cat thyme and silver vine are potent smelly stimulants that can affect cat minds and moods.</p> <p>Ever wondered if these mind-altering substances are safe gifts for our feline friends? And importantly, is it OK to provide these, or is offering catnip to a cat like offering alcohol to a child?</p> <h2>Catnip, cat thyme and silver vine, oh my!</h2> <p>Owners who are concerned about their cats feeling bored and frustrated might offer them fresh or dried catnip (<em>Nepeta cataria</em>), silver vine (<em>Actinidia polygama</em>), cat thyme (<em>Teucrium marum</em>) or other plant materials such as valerian (<em>Valeriana officinalis</em>) and Tatarian honeysuckle (<em>Lonicera tatarica</em>). These last couple <a href="https://bmcvetres.biomedcentral.com/articles/10.1186/s12917-017-0987-6">could offer an alternative</a> if your cat doesn’t respond to catnip.</p> <p>Toys filled with the leaves or extracts of these plants can cause apparently euphoric behaviour in domestic cats (as well as big cats like leopards and jaguars). Not all cats respond this way to these smells, which is <a href="https://bmcbiol.biomedcentral.com/articles/10.1186/s12915-022-01369-1">believed to have a genetic basis</a>.</p> <h2>Are these treats safe for cats?</h2> <p>Cats have a highly developed sense of smell. Some plants release chemical compounds to deter insects or to attract predators of insects that might otherwise destroy them. This includes <a href="https://www.science.org/doi/10.1126/sciadv.aba0721">nepetalactone</a>, an ingredient isolated from catnip and silver vine.</p> <p>Indeed, <a href="https://www.science.org/content/article/why-cats-are-crazy-catnip">it has been argued </a> that exposure to nepetalactone leads to an increase in feel-good hormones in cats. It may also act as a <a href="https://www.science.org/doi/10.1126/sciadv.abd9135">natural mosquito repellent</a> (note that it does not repel all mosquitoes and is not effective for flea or tick control).</p> <p>This may be why sniffing catnip, silver vine and some other plants causes cats to roll on their backs and rub their chins, cheeks and bodies on the plants. Other <a href="https://bmcvetres.biomedcentral.com/articles/10.1186/s12917-017-0987-6">observed behaviours</a> include: licking, shaking their head while carrying plant material in their mouth, drooling, kicking the plant material with their hind feet, and a “wavelike” motion of the skin over their backs as muscles contract and relax.</p> <p>These responses <a href="https://bmcvetres.biomedcentral.com/articles/10.1186/s12917-017-0987-6">generally don’t last long</a>, usually seconds to minutes, before cats relax or resume their normal behaviour.</p> <p>Rather than becoming addicted to these substances, cats are more likely to become habituated and desensitised, with the plants having less effect over time. When sniffed, these plants <a href="https://www.cell.com/iscience/fulltext/S2589-0042(23)01925-9">appear</a> to have <a href="https://bmcbiol.biomedcentral.com/articles/10.1186/s12915-022-01369-1">no adverse effects</a> on cats.</p> <figure><iframe src="https://www.youtube.com/embed/yNUz4zQTA1E?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">Cats (and a dog!) react to the active compound in catnip and silver vine, nepetalactone.</span></figcaption></figure> <h2>Is it ethical to alter the minds of our cats?</h2> <p>When considering how to improve the lives of animals we care for, we tend to focus on whether the benefits outweigh the potential harms.</p> <p>Despite some marketing claims that these plants activates the brain’s opioid system, delivering a “natural high” for cats, there is no evidence these substances actually alter the minds of cats in the same way as alcohol or other drugs alter the minds of humans.</p> <p>The marketing of these cat treats as “kitty crack” or “<a href="https://www.meowijuana.com/">meowijuana</a>” and silver vine sticks as “<a href="https://www.nekopiapets.com.au/product-page/joycat-cat-cigarettes-silvervine-stick">kitty cigarettes</a>” is likely to deter some people from offering their cats <a href="https://bmcbiol.biomedcentral.com/articles/10.1186/s12915-022-01369-1">this kind of olfactory stimulation</a>.</p> <p>Unlike offering alcohol to a child, though, the evidence suggests our cats are OK when given access to these treats. These items won’t induce psychosis and won’t lead to addiction or withdrawal symptoms. And we don’t need to worry about our cats operating heavy machinery or making important decisions under the influence of mind-altering substances!</p> <p>Provided they can walk away at any time, it seems reasonable to let them opt in to a fun time.</p> <p>In fact, we harness the power of cats’ sense of smell in other ways by using <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6435919/">synthetic feline facial pheromones</a>. This can help reduce fear, anxiety and distress in cats. These substances can come in useful in settings such as multi-cat households or when moving house.</p> <h2>How to make sure your cat has the purr-fect time</h2> <p>Offering a range of smells (olfactory stimulation) is just one way to ensure your cat has a varied and interesting life. Here are some tips:</p> <ul> <li> <p>offer cats choices to interact with treats and toys – don’t force them</p> </li> <li> <p>rotate the toys and experiences on offer, so every day offers something fresh</p> </li> <li> <p>offer items that cats can scratch – scratching posts and corrugated cardboard are popular items</p> </li> <li> <p>if you are concerned your cat has swallowed part of a toy or seems unwell, check in with your vet.</p> </li> </ul> <p>Given the short-lived effects of these plant-based olfactory stimulants on cats, it is important that we <a href="https://www.sciencedirect.com/science/article/abs/pii/S0168159119301054">optimise their environment, lifestyle and interactions</a> with humans to improve their welfare. We can’t just rely on catnip or silver vine to give our cats a good life indoors – it’s really up to us!<!-- Below is The Conversation's page counter tag.

A primary course is not recommended for children aged six months to five years <em>without</em> additional risk factors.</p> <h2>Monovalent, bivalent? What’s the difference?</h2> <p><strong>From monovalent</strong></p> <p>The initial COVID vaccines were “monovalent”. They had one target – the original viral strain.</p> <p>But as the virus mutated, we assigned new letters of the Greek alphabet to each variant. This brings us to Omicron. With this significant change, we saw “immune evasion”. The virus had changed so much the original vaccines didn’t provide sufficient immunity.</p> <p><strong>To bivalent</strong></p> <p>So vaccines were updated to target an early Omicron subvariant, BA.1, plus the original ancestral strain. With two targets, these were the first of the “bivalent” vaccines, which were approved in Australia <a href="https://theconversation.com/omicron-specific-vaccines-may-give-slightly-better-covid-protection-but-getting-boosted-promptly-is-the-best-bet-190736">in 2022</a>.</p> <p>Omicron continued to evolve, leading to more “immune escape”, contributing to repeated waves of transmission.</p> <p>The vaccines were updated again in <a href="https://theconversation.com/havent-had-covid-or-a-vaccine-dose-in-the-past-six-months-consider-getting-a-booster-199096">early 2023</a>. These newer bivalent vaccines target two strains – the ancestral strain plus the subvariants BA.4 and BA.5.</p> <p><strong>Back to monovalent</strong></p> <p>Further changes in the virus have meant our boosters needed to be updated again. This takes us to the recent announcement.</p> <p>This time the booster targets another subvariant of Omicron known as XBB.1.5 (sometimes known as <a href="https://theconversation.com/the-kraken-subvariant-xbb-1-5-sounds-scary-but-behind-the-headlines-are-clues-to-where-covids-heading-198158">Kraken</a>).</p> <p>This vaccine is monovalent once more, meaning it has only one target. The target against the original viral strain has been removed.</p> <p>According to advice given to the World Health Organization <a href="https://www.who.int/news/item/18-05-2023-statement-on-the-antigen-composition-of-covid-19-vaccines">in May</a>, this is largely because immunity to this original strain is no longer required (it’s no longer infecting humans). Raising immunity to the original strain may also hamper the immune response to the newer component, but we’re not sure if this is occurring or how important this is.</p> <p>The United States <a href="https://theconversation.com/cdc-greenlights-two-updated-covid-19-vaccines-but-how-will-they-fare-against-the-latest-variants-5-questions-answered-213341">approved</a> XBB.1.5-specific vaccines from Pfizer and Moderna in <a href="https://www.fda.gov/news-events/press-announcements/fda-takes-action-updated-mrna-covid-19-vaccines-better-protect-against-currently-circulating">mid-September</a>.

This variant is the one causing high numbers of cases around the world currently, including in Australia. It is very similar to the XBB version contained in the updated booster.</p> <p>The updated vaccines should also cover <a href="https://theconversation.com/how-evasive-and-transmissible-is-the-newest-omicron-offshoot-ba-2-86-that-causes-covid-19-4-questions-answered-212453">BA.2.86 or Pirola</a>, according to <a href="https://www.tga.gov.au/sites/default/files/2023-10/auspar-spikevax-xbb.1.5-231012.pdf">early results</a> from clinical trials and the US <a href="https://www.cdc.gov/respiratory-viruses/whats-new/covid-19-variant.html">Centers for Disease Control</a>.

So performance of these vaccines against new variants will continue to be closely monitored.</p> <h2>Are they safe?</h2> <p>The <a href="https://www.ebs.tga.gov.au/ebs/picmi/picmirepository.nsf/pdf?OpenAgent=&amp;id=CP-2023-PI-02409-1&amp;d=20231117172310101">safety</a> of the updated vaccines has also been shown to be similar to previous versions. Studies <a href="https://www.medrxiv.org/content/10.1101/2023.08.22.23293434v2">comparing them</a> found no significant difference in terms of the adverse events reported.</p> <p>Given the availability of the updated vaccines, some countries have removed their approval for earlier versions. This is because newer versions are a closer match to currently circulating strains, rather than any safety issue with the older vaccines.</p> <h2>What happens next?</h2> <p>The availability of updated vaccines is a welcome development, however this is not the end of the story. We need to make sure eligible people get vaccinated.</p> <p>We also need to acknowledge that vaccination should form part of a comprehensive strategy to limit the impact of COVID from now on. That includes measures such as mask wearing, social distancing, focusing on ventilation and air quality, and to a lesser degree hand hygiene. Rapidly accessing antivirals if eligible is also still important, as is keeping away from others if you are infected.<!-- Below is The Conversation's page counter tag.

A COVID inquiry has been announced. But is COVID still a thing? Do I need a booster?

It’s still with us.</p> <p>The Omicron variant <a href="https://theconversation.com/how-evasive-and-transmissible-is-the-newest-omicron-offshoot-ba-2-86-that-causes-covid-19-4-questions-answered-212453">continues to mutate</a> and <a href="https://www.abc.net.au/news/2023-09-21/new-covid-strain-variant-pirola-ba-2-86-in-australia-symptoms/102873304">new sub-variants</a> emerge. For instance, the highly-mutated BA.2.86 (known as Pirola) has just been <a href="https://www.abc.net.au/news/2023-09-21/new-covid-strain-variant-pirola-ba-2-86-in-australia-symptoms/102873304">detected</a> in Australia.</p> <p>The SARS-CoV-2 virus, which causes COVID, then becomes more adept at evading immunity from infections and vaccines.</p> <p>COVID is not yet predictably seasonal and we expect waves every three to six months. The United States has seen a <a href="https://covid.cdc.gov/covid-data-tracker/#trends_weeklyhospitaladmissions_select_00">threefold increase</a> in hospitalisations since mid-July due to waning immunity and the <a href="https://theconversation.com/the-who-has-declared-eris-a-variant-of-interest-how-is-it-different-from-other-omicron-variants-211276">EG.5 sub-variant</a> (known as Eris).</p> <p>The United Kingdom has also seen a <a href="https://twitter.com/DrEricDing/status/1702790082749448202?t=FLc5f9FoMS6ksioFS8ATpA&amp;s=09">significant increase</a> in adult and child hospitalisations due to COVID in the past month.</p> <p>In Australia, more than <a href="https://www.worldometers.info/coronavirus/country/australia/">5,000 people</a> have died due to COVID so far this year. Excess deaths from any cause are <a href="https://www.abs.gov.au/statistics/health/causes-death/provisional-mortality-statistics/latest-release">13% higher</a> than expected. We expect many of these are related to COVID.</p> <p>The median age of COVID deaths is <a href="https://www.abs.gov.au/articles/covid-19-mortality-australia-deaths-registered-until-31-july-2023">around 85 years old</a> in Australia. But there were 267 reported deaths in people under 50 until the end of July 2023; some may have had weaker immune systems.</p> <p>The impacts of <a href="https://www.aph.gov.au/longandrepeatedcovid">long COVID and re-infections</a> are significant, which <a href="https://www.abc.net.au/news/2022-07-20/younger-active-female-data-reveals-long-covid-profile/101251352">one study shows</a> mainly affects people of working age and most commonly women.</p> <h2>I’ve had a booster. Does that still protect me?</h2> <p>We know immunity from COVID vaccines wanes over time. In a paper published in May, a <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2804451?utm_source=For_The_Media&amp;utm_medium=referral&amp;utm_campaign=ftm_links&amp;utm_term=050323">systematic review</a> of 40 studies showed by how much. Protection by the first two doses of the vaccine (known as the primary series) against symptomatic infection from Omicron waned from almost 53% one month after the second dose to just over 14% after six months.</p> <p>The same review found a booster (third or fourth dose) increased protective immunity to the same levels as the primary series. However, that immunity waned to just 30% nine months later.</p> <p>A number of studies have shown protection against severe disease and death from the Omicron variant also wanes over time. For example, <a href="https://www.thelancet.com/journals/laninf/article/PIIS1473-3099(23)00365-1/fulltext#seccestitle10">a UK study</a> found a primary series plus a bivalent booster (targets two strains) provided 53% protection against hospitalisation four weeks after the booster among people aged 50 or over. Protection dropped to 36% at ten weeks.</p> <p>An <a href="https://papers.ssrn.com/sol3/papers.cfm?abstract_id=4445191">Australian study</a>, yet to be independently verified by other researchers, suggests protection against death from COVID also wanes. Of 3.8 million adults over 65 years, protection of a third dose booster against death from COVID waned from an estimated 93% within three months to 56% after six months.</p> <p>So we believe a reasonable interpetation of the above data is to recommend a booster every six months in people aged 75 and older, and younger people with impaired immune systems.</p> <p>But in Australia, just over <a href="https://www.health.gov.au/sites/default/files/2023-09/covid-19-vaccine-rollout-update-15-september-2023.pdf">50%</a> of people aged 75 or older have received a booster in the past six months; only about 38% of people aged 65-74 and about 9% in those aged 18-64 years.</p> <h2>I’ve had COVID recently. Surely that’s enough</h2> <p>There is a widespread perception that if you’ve been infected with COVID and have had the primary series of the vaccine then you’re immune and, therefore, don’t need to get a booster. This is commonly described as having “hybrid immunity”.</p> <p>However, a very <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(22)02465-5/fulltext">large study</a> across 19 countries found infection conferred different levels of immunity, depending on the variant. While infection with COVID effectively protected against reinfection by the original, Alpha, Beta and Delta variants, this was much less effective against the Omicron BA.1 variant. Since BA.1, there have been many new sub-variants that are even more adept at evading immunity.</p> <h2>Who can get a booster?</h2> <p>Earlier this month, the Australian Technical Advisory Group on Immunisation (ATAGI) <a href="https://www.health.gov.au/news/atagi-update-on-the-covid-19-vaccination-program">recommended</a> all adults aged 75 or older “should receive” an additional dose of the bivalent vaccine if six months have passed since their last dose. Additionally, people aged 65-74 and immunocompromised younger adults should “consider” an additional dose.</p> <p>ATAGI argues that the baseline risk of severe illness in people under 65 is low if they have already been vaccinated, and particularly if they have also been infected. So, a further 2023 dose for this group would offer little additional benefit, even if it has been more than six months since their last dose.</p> <p>The US has taken a different approach. Last week, the Centers for Disease Control and Prevention <a href="https://www.cdc.gov/media/releases/2023/p0912-COVID-19-Vaccine.html">recommended</a> all people over six months who have not received a COVID vaccine in the previous two months should get a dose of the newly approved monovalent (single strain) vaccines. These have been developed by Pfizer and Moderna to specifically <a href="https://www.fda.gov/news-events/press-announcements/fda-takes-action-updated-mrna-covid-19-vaccines-better-protect-against-currently-circulating">target the XBB.1.5</a> sub-variant of Omicron. <a href="https://www.canada.ca/en/health-canada/news/2023/09/health-canada-authorizes-moderna-covid-19-vaccine-targeting-the-omicron-xbb15-subvariant.html">Health Canada</a> has adopted similar recommendations.</p> <p>These new monovalent vaccines are expected <a href="https://www.science.org/content/article/should-i-get-covid-19-booster">to be effective</a> in preventing infection by recently emerging Omicron sub-variants, such as EG.5 and FL.1.51 derived from the XBB.1.5 sub-variant, and the newer highly mutated <a href="https://www.gov.uk/government/publications/investigation-of-sars-cov-2-variants-of-concern-variant-risk-assessments/risk-assessment-for-sars-cov-2-variant-v-23aug-01-or-ba286">BA.2.86</a>, which arose from an earlier sub-variant and is a significant evolutionary leap.</p> <p>While Canada and the US move into the northern hemisphere winter, Australians should not believe they are at lower risk during the summer. After all, <a href="https://www.worldometers.info/coronavirus/country/australia/">two large COVID waves</a> in Australia were in the summers of 2021/22 and 2022/23.</p> <p>Monovalent XBB.1.5 vaccines are not yet available in Australia, but are being evaluated by the <a href="https://www.tga.gov.au/products/covid-19/covid-19-vaccines/covid-19-vaccines-regulatory-status">Therapeutic Goods Administration</a>. So, in the future, Australia’s advice about who’s eligible for a booster, and which type of booster, may change.</p> <h2>So, how do I decide if I need a booster now?</h2> <p>There is evidence in Australia of <a href="https://www.abc.net.au/news/2023-09-21/new-covid-strain-variant-pirola-ba-2-86-in-australia-symptoms/102873304">growth of</a> the newer subvariants, including the detection of BA.2.86. So all Australians aged 75 and over who have not had a booster in the past six months should immediately have the currently available bivalent vaccine.</p> <p>Younger age groups may wait until further ATAGI advice about the new monovalent vaccines.</p> <h2>COVID is not over</h2> <p>While there is no need for alarm, Australians need to be aware of the ongoing significant impacts of COVID. The SARS-CoV-2 virus is still a formidable foe as it continues to mutate.</p> <p>COVID vaccines will be <a href="https://www.pm.gov.au/media/improving-future-preparedness-inquiry-response-covid-19-pandemic">among the topics</a> the newly announced inquiry will investigate.</p> <p>But we cannot rely on vaccines alone. Avoiding (re)infection is also vital. Breathe <a href="https://www.coronavirus.vic.gov.au/ventilation">clean indoor air</a>, wear <a href="https://www.cdc.gov/coronavirus/2019-ncov/prevent-getting-sick/types-of-masks.html">high quality masks</a> and get tested so you can access <a href="https://www.health.gov.au/health-alerts/covid-19/treatments/eligibility">antivirals</a> if eligible.<!-- Below is The Conversation's page counter tag.

The happiness diet: 7 foods to boost your mood

<p><strong>Mood boosting foods worth adding to your shopping trolley</strong></p> <p>For decades, our culture has focused on the connection between healthy eating and physiological wellness – most of all, related to weight. But out of a pandemic that made mental health a hot topic, you might also be gaining an awareness that the food you eat can seriously affect your mind.</p> <p>Research published in The British Medical Journal says diet plays a major role in how both our body and our brain are feeling. Poor nutrition can contribute to depression, anxiety, aggression (there’s a reason the word “hangry” exists!). But improving your diet, and knowing the right foods to eat, may help your mental health.</p> <p>Dietitian and certified intuitive eating counsellor Rachel Engelhart says certain foods can support your body’s processes that are responsible for positive moods and strong energy levels. Here’s Engelhart’s list of the greatest mood-boosting foods.</p> <p><strong>Fatty fish</strong></p> <p>Seafood like salmon, mackerel and canned tuna are rich in omega-3 fatty acids, which are ‘healthy fats’ with benefits throughout your body – from your heart to your eyes – and your brain.</p> <p>“Omega-3 fatty acids are anti-inflammatory and have the ability to cross into the brain, having a direct effect on mood-regulating molecules and neurotransmitters there,” says registered dietitian Kelsey Lorencz. Research has consistently linked low levels of omega-3s with mood disorders like depression and anxiety – and, according to a review published in Frontiers in Physiology, most of us don’t get enough omega-3 fats in our diet.</p> <p><strong>Yoghurt</strong></p> <p>According to Lorencz, “The bacteria in your gut can actually produce feel-good neurotransmitters like serotonin and dopamine.”</p> <p>Research has identified a particular bacterium that may have a strong impact on triggering these chemicals: a strain called Lactobacillus. One study published in the journal Nature found that feeding our gut with this good bacteria – found naturally in foods like yoghurt, kefir, and sauerkraut – doesn’t just keep the blues at bay, it can increase our resilience in the face of stress.</p> <p><strong>Bananas</strong></p> <p>Bananas aren’t just shaped like a smile – they’re a mood-boosting powerhouse. That’s in part because they’re also high in vitamin B6, one nutrient behind the production of the ‘happiness hormone’ serotonin. Bananas contain prebiotic fibre, which, along with that Lactobacillus, are essential for gut health that promotes a happy brain.</p> <p><strong>Cottage cheese</strong></p> <p>“The amino acid L-tyrosine is needed to make dopamine and norepinephrine, two neurotransmitters that affect our mood and can easily become depleted,” Lorencz says. She points to high sources like soy products, chicken, fish, nuts, seeds, avocados and bananas. But cottage cheese has a whopping amount of this amino acid, along with a few other mood-boosters in its arsenal. It’s high in protein, which is essential for our body to make and use its mood-promoting hormones, Engelhart says. (This protein is casein protein, which our body absorbs more slowly, sustaining energy levels, and may contribute to elevated moods, according to ongoing research.)</p> <p>Cottage cheese also contains selenium, a mineral that Nutrients research has suggested may be linked with lower rates of depression.</p> <p><strong>Nuts and seeds</strong></p> <p>Magnesium is a mineral that supports our body’s energy production – and not getting enough can lead to irritability, anxiety, sleeplessness and agitation, says Lorencz. Nuts like almonds, walnuts, cashews and seeds like pumpkin, chia and sesame are great sources of this vital nutrient, as well as tryptophan, an amino acid associated with good moods.</p> <p>Nuts and seeds can also be great vegetarian sources of those crucial omega-3 fatty acids.</p> <p><strong>Oysters</strong></p> <p>The ages-old wives’ tale about oysters as aphrodisiacs is still out for debate, but oysters can elevate one’s mood. They pack the highest zinc content of any food – a nutrient that’s linked with anxiety and depression when we’re deficient, says Lorencz – and contain tyrosine, an amino acid that helps our body produce the ‘feel good’ hormone dopamine.</p> <p>That’s great news for the shellfish-loving set. However, if you aren’t a fan of oysters, you can get this one-two mood-boosting punch from food like eggs, nuts and legumes.</p> <p><strong>Your favourite treat</strong></p> <p>“Having a varied diet is the best way to set your body up to produce the ‘feel good’ hormones that it needs,” Engelhart says, adding an important point: while this nutritious balance is important, so is treating yourself to food you enjoy. “So many of my clients are hard on themselves and rather judgmental around their food choices, and it negatively impacts their mood,” she says. “Sprinkling our day with a delicious coffee, a yummy dessert, or one of our favourite restaurant meals is also an important way to positively impact our mental health.”</p> <p>And if you want to be strategic about that treat, reach for some dark chocolate. Chocolate contains natural serotonin, and 2022 research found that dark chocolate has prebiotic effects in our gut, supporting stronger mental health.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.com.au/healthsmart/conditions/mental-health/the-happiness-diet-7-foods-to-boost-your-mood" target="_blank" rel="noopener">Reader's Digest</a>.</em></p>

“Done with the vaccine”: Karl Stefanovic blasts fifth booster

<p>Karl Stefanovic has once again sparked controversy after declaring he is “done with the vaccine.”</p> <p>Karl shocked viewers after expressing concerns that the jab could cause “heart issues” as the Australian Technical Advisory Group (ATAGI) updated its vaccine recommendations. </p> <p>According to the ATAGI, as of February 20, anyone aged 18 and over who has not had the COVID vaccine or has not contracted the virus in the past six months will be eligible to get another shot - opening up a fourth dose for Aussies aged 19-29 and a fifth dose for those 65 and over. </p> <p>“As you know, I am not a glowing ambassador for more than two shots,” Stefanovic said.</p> <p>The Today show host then questioned whether another dose would be able to fight new strains of the virus, stating he is aware of people “over the age of 60 who are still incredibly nervous about getting it."</p> <p>“The other thing that I am concerned about, if I have another dose, is that I may get complications,” he said. </p> <p>The host’s guest, medical expert Dr Nick Coatsway insisted Australians aged 60 and over “needn’t be” scared of the jab but added that the conceded boosters are only a temporary solution.</p> <p>“Let’s understand the science, if you get a fifth dose your protection is enhanced for around about 8-12 weeks and then it returns after the fourth dose or the third dose,” Dr Coatsworth said.</p> <p>The ATAGI has again emphasised the importance of Aussies who are already eligible, including people over 65, to get their booster in 2023 as they remain at high risk of severe disease and death from COVID. </p> <p>Currently, there is no additional booster available to those 18 and below, with the exception of children aged 5-17 who are at high risk of developing a severe illness.</p> <p><em>Image credit: Getty</em></p>

Kendall Roy’s playlist: why hip hop is the perfect counterpoint for Succession’s entitled plutocrats

The businessman is riding in the back of a limo, listening to <em><a href="https://www.youtube.com/watch?v=ny6hwUOFvlw">An Open Letter to NYC</a></em> by the Beastie Boys, as the hustle and bustle of Manhattan rolls by.</p> <p>But when the backing track fades, <a href="https://www.youtube.com/watch?v=3eTTkxM8QLE&amp;ab_channel=OpeningScenes">Kendall’s own voice is revealed</a>, thin and childish, rapping along to the lyrics about skyscrapers and Wall Street traders. This wannabe hip hop businessman persona is at the core of Kendall’s deeply conflicted character.</p> <p>This persona is in full bloom in a memorable season two episode, where Kendall performs L to the OG, a rap tribute to his father Logan Roy (Brian Cox), earning him the nickname “Ken.W.A.” from brother Roman (Kieran Culkin), a la the infamous Compton rap group NWA.</p> <p>As I explain in my book, <em><a href="https://criticalexcess.org/">Critical Excess: Watch the Throne and the New Gilded Age</a></em>, corporate board rooms and <a href="https://www.dukeupress.edu/the-real-hiphop">hip hop ciphers</a> are no longer as incompatible as they might seem. This is exemplified through American rap superstars Jay Z and Kanye West’s (now known as Ye) collaborative “<a href="https://genius.com/Jay-z-and-kanye-west-otis-lyrics">luxury rap</a>” album, <em>Watch the Throne</em> (2011).</p> <figure><iframe src="https://www.youtube.com/embed/6dUDQTc-9kM?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">Kendall rapping in season two of Succession.</span></figcaption></figure> <p>In season four, <a href="https://www.youtube.com/watch?v=GNbfEC-AeHs&amp;ab_channel=ob9RJ2mJhoMPHH">Kendall listens</a> to <a href="https://www.youtube.com/watch?v=IHiFMW8s6zk&amp;ab_channel=JAYZ-Topic">Jay Z’s <em>The Takeover</em></a> (2001) on his way to work in the ATN news studio. It’s not surprising that Jay Z is a favourite. The rapper-turned-entrepreneur once rapped the lines: “I’m not a businessman, I’m a business, man!” in his verse on Ye’s <em><a href="https://www.youtube.com/watch?v=aI0jNu-G5Hw&amp;ab_channel=KanyeWest-Topic">Diamonds from Sierra Leone</a></em> (2005), an attitude it’s easy to imagine Kendall aligning himself with.</p> <p>It’s also no coincidence that this dysfunctional family is named Roy, French for “king”, another link to Watch the Throne and the hustle to become “<a href="https://www.complex.com/music/2020/05/who-is-king-of-new-york">king of New York</a>”.</p> <p>Real-life media mogul family, the Murdochs, are widely believed to have <a href="https://www.vanityfair.com/news/2023/04/rupert-murdoch-cover-story">inspired <em>Succession</em></a>. But the hip hop connection is particularly uncanny. In 1995, Rupert Murdoch’s youngest son, James, bankrolled the hot new hip hop label Rawkus Records. Soon thereafter Murdoch’s News Corp bought a majority share in Rawkus and artists reportedly <a href="https://www.theguardian.com/media/2011/jul/11/james-murdoch-hip-hop">started complaining about unpaid royalties</a>.</p> <h2>Hip hop as Kendall’s hype music</h2> <p>Rap music is <a href="https://www.jstor.org/stable/10.5406/musimoviimag.2.1.0026">repeatedly used</a> to show Kendall’s need for a boost of confidence – a need once satisfied by <a href="https://www.youtube.com/watch?v=y9gIa3Xqycg">his substance abuse</a>.</p> <p>Hip hop pioneer <a href="https://www.allmusic.com/artist/krs-one-mn0000359119/biography">KRS-One</a> reportedly once likened hip hop to a “<a href="https://floodmagazine.com/42937/quelle-chris-being-you-is-great-i-wish-i-could-be-you-more-often/">confidence sandwich</a>” for its ability to help America’s forgotten underclasses find the strength to get up and fight the good fight, from enduring the daily grind to organising for a better world. But what happens when this swag burger is blaring in the ears of an out-of-touch CEO?</p> <figure><iframe src="https://www.youtube.com/embed/GNbfEC-AeHs?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">Kendall listening to Jay Z’s The Takeover.</span></figcaption></figure> <p>As the late, great Black music critic <a href="https://www.penguinrandomhouse.com/books/176649/everything-but-the-burden-by-edited-by-greg-tate/">Greg Tate</a> suggests, hip hop has been a site of “the Elvis effect” for decades, with white artists and businessmen profiting mightily from Black creative cultures.

Happy songs: these are the musical elements that make us feel good

<p>Music has a unique power <a href="https://www.researchgate.net/profile/Daniel-Vaestfjaell/publication/258173113_Emotion_Induction_through_Music_A_Review_of_the_Musical_Mood_Induction_Procedure/links/02e7e527c81174366e000000/Emotion-Induction-through-Music-A-Review-of-the-Musical-Mood-Induction-Procedure.pdf">to affect the way people feel</a> and many people use music to enhance or change their mood, channel emotions and for psychological support. </p> <p>The strong emotional impact of music is derived from its profound physical and psychological effects. For example, listening to relaxing music often has a positive impact on the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1959222/">autonomic nervous system</a> (which regulates many key bodily functions), by slowing breathing, regulating heart rate, lowering blood pressure and reducing muscle tension.</p> <p>Listening to music also affects us at a deep physiological level, as it has a strong impact on the <a href="http://www.downloads.imune.net/medicalbooks/Neurochemistry%20of%20music.pdf">endocrine system</a>, which is responsible for hormone production. </p> <p>Music can stimulate the release of the neurotransmitters which affect experiences of pleasure by increasing the production of dopamine (the reward hormone), reducing levels of cortisol (the stress hormone) and increasing salivary immunoglobulin A – an antibody responsible for strengthening the immune system.</p> <p>Of course, these benefits are only experienced if we listen to music that we enjoy. <a href="http://www.brainvitge.org/papers/Science-2013-Salimpoor-216-9.pdf">Familiarity</a> also affects enjoyment, but even new music can stimulate positive physical and psychological responses if it is similar to other music that we like.</p> <p>Music we don’t like can have a strong adverse effect upon mood and wellbeing. Individual differences mean emotional <a href="https://journals.sagepub.com/doi/abs/10.1177/0305735618754688?journalCode=poma">reactions to songs differ</a> depending on the participant’s preferences and associations they might have with the music. If we don’t like the song (or it brings back negative memories), it won’t make us happy, regardless of the quality.</p> <h2>Creating a personal soundscape</h2> <p>Portable listening devices and music streaming platforms have made it possible to choose from an unprecedented selection of musical styles. People can now listen to their favourite music any time, anywhere. </p> <p>This means music can be used to create a personal soundscape. This is common when using public transport, for example, as many passengers use headphones to create an individualised sonic environment as a distraction from the less pleasant aspects of travelling on crowded and noisy transport systems.</p> <p>In a <a href="https://www.prnewsblog.com/news/health-wellbeing/15034/music-psychologist-reveals-the-formula-for-the-happiest-song-ever/">recent survey</a>, 71% of 2,000 participants reported that music was the strongest influence on their mood and almost 75% regularly listened to music to cheer themselves up. In response to these findings, I conducted a review of published research, to find out which musical features tend to be present in “happy” songs.</p> <p>It should be remembered that musical preferences and expectations are culture dependent. For example, some Asian cultures have different associations between positive/negative emotions and major/minor chords, so <a href="https://royalsocietypublishing.org/doi/10.1098/rsos.170952">western “happy songs” may not be globally interpreted as such.</a></p> <p>Within western cultures, there are certain components of popular music which are commonly linked with positive emotions. Music that is perceived as “happy” is usually written in a major key with a bright tone, featuring instruments with a bright timbre, such as trumpets or electric guitars.</p> <p>“Happy” music usually adds <a href="https://royalsocietypublishing.org/doi/10.1098/rsos.170952">the seventh note of the scale</a> to the main three notes in the chord. This creates a brief feeling of tension – or pleasurable expectation – followed by relief or resolution when the harmonic progression proceeds as our previous listening experience predicts.</p> <p>For many people, listening to music becomes an immersive <a href="https://www.frontiersin.org/articles/10.3389/fpsyg.2015.00906/full">flow experience</a> which can distract from everyday concerns. Active musical participation through dancing or singing along brings additional enjoyment. </p> <p>A simple, consistent rhythm based on two or four beats in a bar increases a song’s “<a href="https://mashable.com/ad/feature/science-of-pop-music">danceability</a>”, while a binary structure – verse-chorus-verse-chorus – helps to establish familiarity so the song quickly becomes “<a href="https://www.york.ac.uk/news-and-events/features/pop-science/">sing-alongable</a>”.</p> <p>People generally <a href="https://mashable.com/ad/feature/science-of-pop-music">prefer familiar music</a>, or music which quickly becomes memorable. The most enjoyable songs are likely to be those which strike a satisfying <a href="https://www.sciencedirect.com/science/article/pii/S0960982219312588">balance between predictability and surprise</a>, providing an experience familiar enough to be pleasurable while avoiding being too simplistic or formulaic.</p> <p>Unexpected changes can intensify emotional responses. Listeners often derive the most pleasure from music when they are fairly sure about what will happen next but then an unexpected chord progression or key change provides a surprise.</p> <p>Based on previous experiences, listeners develop expectations about a piece of music. While familiar music tends to give the most pleasure, it also needs to contain enough “surprise” elements to retain enough interest to create a state of flow. This explains the use of a bridge or the middle eight (a section which is different from the verse and chorus) in many songs.</p> <p>Although “happy songs” are usually written in a <a href="https://www.researchgate.net/publication/301724912_Beyond_Happiness_and_Sadness_Affective_Associations_of_Lyrics_with_Modality_and_Dynamics">major key</a>, they sometimes include a section in a minor key to add interest. </p> <p>Good Vibrations by the Beach Boys begins with a verse in a minor key and then creates a strong emotional uplift as it switches into a bright major key for the chorus.</p> <h2>The speed of happiness</h2> <p>Faster music tends to induce more positive emotions than slower music. Research suggests that music that is perceived as happy is usually performed at a tempo between <a href="https://mymodernmet.com/10-happy-songs/">140 and 150 beats per minute (BPM)</a>. Songs people have said they use to <a href="https://open.spotify.com/playlist/7k00dawKjXgBBuq2nZyHmO">improve their mood</a> include Queen’s Don’t Stop Me Now at 156 BPM.</p> <p>Tempo is a confounding variable because <a href="https://journals.sagepub.com/doi/abs/10.1177/0305735618754688?journalCode=poma">faster music increases arousal/excitement</a>, but this may not always be associated with happiness. There may also be <a href="https://www.anderson.ucla.edu/documents/areas/fac/marketing/mogilner/Mogilner_Shifting_Meaning_of_Happiness_SPPS_2011.pdf">age-related differences</a> in interpretation. </p> <p>What is certain is that music can have a profound effect on our sense of wellbeing. Just stick on <a href="https://www.youtube.com/watch?v=pTdihu-mp90">James Brown’s I Got You</a> (or whatever might tempt you to do a happy dance) and start to feel good.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/happy-songs-these-are-the-musical-elements-that-make-us-feel-good-201342" target="_blank" rel="noopener">The Conversation</a>. </em></p>

Let’s dance! How dance classes can lift your mood and help boost your social life

<p>If your new year’s resolutions include getting healthier, exercising more and lifting your mood, dance might be for you.</p> <p>By dance, we don’t mean watching other people dance on TikTok, as much fun as this can be. We mean taking a dance class, or even better, a few.</p> <p>A growing body of <a href="https://www.tandfonline.com/doi/full/10.1080/17482631.2020.1732526">research shows</a> the benefits of dance, regardless of the type (for example, classes or social dancing) or the style (hip hop, ballroom, ballet). Dance boosts our wellbeing as it improves our emotional and physical health, makes us feel less stressed and more socially connected.</p> <p>Here’s what to consider if you think dance might be for you.</p> <h2>The benefits of dance</h2> <p>Dance is <a href="https://journals.sagepub.com/doi/10.1177/1077800417745919">an engaging and fun</a> way of exercising, learning and meeting people. A review of the evidence <a href="https://www.tandfonline.com/doi/full/10.1080/17482631.2020.1732526">shows</a> taking part in dance classes or dancing socially improves your health and wellbeing regardless of your age, gender or fitness.</p> <p>Another review focuses more specifically on benefits of dance across the lifespan. It <a href="https://doi.org/10.1080/17482631.2021.1950891">shows</a> dance classes and dancing socially at any age improves participants’ sense of self, confidence and creativity.</p> <p>Researchers have also looked at specific dance programs.</p> <p>One UK-based dance program for young people aged 14 <a href="https://doi.org/10.1080/14647893.2011.561306">shows</a> one class a week for three months increased students’ fitness level and self-esteem. This was due to a combination of factors including physical exercise, a stimulating learning environment, positive engagement with peers, and creativity.</p> <p>Another community-based program for adults in hospital <a href="https://doi.org/10.1080/17533015.2020.1725072">shows</a> weekly dance sessions led to positive feelings, enriches social engagement and reduced stress related to being in hospital.</p> <p>If you want to know how much dance is needed to develop some of these positive effects, we have good news for you.</p> <p>A useful hint comes from a <a href="https://bmcpublichealth.biomedcentral.com/articles/10.1186/s12889-015-2672-7">study</a> that looked exactly at how much creative or arts engagement is needed for good mental health – 100 or more hours a year, or two or more hours a week, in most cases.</p> <h2>Dance is social</h2> <p>But dance is more than physical activity. It is also a community ritual. Humans have <a href="https://www.jstor.org/stable/223398">always danced</a>. We still do so to mark and celebrate transitory periods in life. Think of how weddings prompt non-dancers to move rhythmically to music. Some cultures dance to celebrate childbirth. Many dance to celebrate religious and cultural holidays.</p> <p>This is what inspired French sociologist <a href="https://iep.utm.edu/emile-durkheim/">Emile Durkheim</a> (1858-1917) to explore how dance affects societies and cultures.</p> <p>Durkheim <a href="https://archive.org/search?query=external-identifier%3A%22urn%3Aoclc%3Arecord%3A689172179%22">saw</a> collective dance as a societal glue – a social practice that cultivates what he called “collective effervescence”, a feeling of dynamism, vitality and community.</p> <p>He observed how dance held cultures together by creating communal feelings that were difficult to cultivate otherwise, for example a feeling of uplifting togetherness or powerful unity.</p> <p>It’s that uplifting feeling you might experience when dancing at a concert and even for a brief moment forgetting yourself while moving in synchrony with the rest of the crowd.</p> <p>Synchronous <a href="https://www.journals.uchicago.edu/doi/10.1086/529447">collective activities</a>, such as dance, provide a pleasurable way to foster social bonding. This is due to feelings Durkheim noticed that we now know as transcendental emotions – such as joy, awe and temporary dissolution of a sense of self (“losing yourself”). These can lead to feeling a part of something bigger than ourselves and help us experience social connectedness.</p> <p>For those of us still experiencing social anxiety or feelings of loneliness due to the COVID pandemic, dance can be a way of (re)building social connections and belonging.</p> <p>Whether you join an online dance program and invite a few friends, go to an in-person dance class, or go to a concert or dance club, dance can give temporary respite from the everyday and help lift your mood.</p> <h2>Keen to try out dance?</h2> <p>Here’s what to consider:</p> <ul> <li> <p>if you have not exercised for a while, start with a program tailored to beginners or the specific fitness level that suits you</p> </li> <li> <p>if you have physical injuries, check in with your GP first</p> </li> <li> <p>if public dance classes are unappealing, consider joining an online dance program, or going to a dance-friendly venue or concert</p> </li> <li> <p>to make the most of social aspect of dance, invite your friends and family to join you</p> </li> <li> <p>social dance classes are a better choice for meeting new people</p> </li> <li> <p>beginner performance dance classes will improve your physical health, dance skills and self-esteem</p> </li> <li> <p>most importantly, remember, it is not so much about how good your dancing is, dance is more about joy, fun and social connectedness.</p> </li> </ul> <p>In the words of one participant in our (yet-to-be published) research on dance and wellbeing, dance for adults is a rare gateway into fun, "there’s so much joy, there’s so much play in dancing. And play isn’t always that easy to access as an adult; and yet, it’s just such a joyful experience. I feel so happy to be able to dance."</p> <p><em>Images: Getty</em></p> <p><em style="box-sizing: border-box; color: #212529; font-family: -apple-system, 'system-ui', 'Segoe UI', Roboto, 'Helvetica Neue', Arial, sans-serif, 'Apple Color Emoji', 'Segoe UI Emoji', 'Segoe UI Symbol', 'Noto Color Emoji'; font-size: 16px; background-color: #ffffff;">This article originally appeared on <a href="https://theconversation.com/lets-dance-how-dance-classes-can-lift-your-mood-and-help-boost-your-social-life-197692" target="_blank" rel="noopener">The Conversation</a>. </em></p>

Your home, office or uni affects your mood and how you think. How do we know? We looked into people’s brains

<p>Think of a time when you felt vulnerable. Perhaps you were in a hospital corridor, or an exam hall, about to be tested. Now, focus on the building you were in. What if, without you knowing, the design of that space was affecting you?</p> <p>We study <a href="https://psychology.org.au/community/advocacy-social-issues/environment-climate-change-psychology/psychologys-role-in-environmental-issues/what-is-environmental-psychology" target="_blank" rel="noopener">environmental psychology</a>, a growing field of research investigating the relationship between humans and the external world. This includes natural, and human-made environments, such as buildings.</p> <p>Researchers could just ask people what they feel when inside a building – how pleasant or unpleasant they feel, the intensity of that feeling, and how in control they feel.</p> <p>But we use neuroscience to see how the brain is stimulated when inside a building. The idea is for people to one day use that information to design better buildings – classrooms that help us concentrate, or hospital waiting rooms that reduce our anxiety.</p> <p><strong>Why study buildings this way?</strong></p> <p>We spend <a href="https://www.health.vic.gov.au/chief-health-officer/healthy-indoor-environments" target="_blank" rel="noopener">at least 80% of our lives</a> inside buildings. So it is critical we understand whether the buildings we occupy are affecting our brain and body.</p> <p>Buildings – hospitals, schools, offices, homes – are often complex. They can have various contents (fixtures, fittings and objects), levels of comfort (such as the light, sound, and air quality). Other people occupy the space.</p> <p>There are also a range of design characteristics we can notice inside a building. These include colour (wall paint, chair colour), texture (carpet tiles, timber gym floor), geometry (curved walls or straight, angular ones), and scale (proportions of height and width of a room).</p> <p><strong>What did we do?</strong></p> <p>We wanted to see what effect changing some of these characteristics had on the brain and body.</p> <p>So we asked participants to sit in the middle of a virtual-reality (VR) room for 20 minutes.</p> <p>We designed the room with a door (to show height) and chair (to show depth), keeping it empty of other cues that might influence people. We modelled the room using dimensions set by the local building code.</p> <p>Other studies have compared <a href="https://doi.org/10.1016/j.jenvp.2019.101344" target="_blank" rel="noopener">complex environments</a>, which are more realistic to everyday life. But we chose to use a simple VR room so we could understand the impact of changing one characteristic at a time.</p> <p>To measure brain activity, we used a technique called electroencephalography. This is where we placed electrodes on the scalp to measure electrical activity as brain cells (neurons) send messages to each other.</p> <figure class="align-center zoomable"><em><a href="https://images.theconversation.com/files/485808/original/file-20220921-13-7qqec9.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/485808/original/file-20220921-13-7qqec9.jpg?ixlib=rb-1.1.0&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/485808/original/file-20220921-13-7qqec9.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=429&fit=crop&dpr=1 600w, https://images.theconversation.com/files/485808/original/file-20220921-13-7qqec9.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=429&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/485808/original/file-20220921-13-7qqec9.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=429&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/485808/original/file-20220921-13-7qqec9.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=539&fit=crop&dpr=1 754w, https://images.theconversation.com/files/485808/original/file-20220921-13-7qqec9.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=539&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/485808/original/file-20220921-13-7qqec9.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=539&fit=crop&dpr=3 2262w" alt="Fitting cap of electrodes" /></a></em><figcaption><em><span class="caption">Participants wore a cap covered in electrodes to detect electrical activity in the brain.</span> <span class="attribution"><span class="source">Donna Squire</span>, <span class="license">Author provided</span></span></em></figcaption></figure> <p>We also monitored the body by measuring heart rate, breathing and sweat response.

This is the pattern we’d typically see if you were looking at something that you felt positive about, such as a smiling face, or a scenic sunset.</p> <p>Changing the size and colour of a room also changed <a href="https://doi.org/10.1002/hbm.26061" target="_blank" rel="noopener">brain network communication</a>. This is when different parts of the brain “talk” to one another. This could be communication between parts of the brain involved in seeing and attention, the type of communication needed when viewing a complex scene, such as scanning a crowded room to spot a friend.</p> <p>The rooms also changed the participants’ autonomic response (their patterns of breathing, heart activity and sweating).</p> <hr /> <figure><iframe title="YouTube video player" src="https://www.youtube.com/embed/dPHOQvLOCD4" width="100%" height="400" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><em>Your brain and body give away what you feel and think about different rooms, even if you can’t tell us yourself.</em></figcaption></figure> <hr /> <p>Despite these brain and body responses, we found no change in what participants told us about their emotions in each of these different conditions.</p> <p>This suggests the need to shift from just asking people about their emotions to capturing effects they may not be consciously perceive or comprehend.</p> <p><strong>What does this mean for designing buildings?</strong></p> <p>This work tells us that characteristics of buildings have an impact on our brains and our bodies.</p> <p>Our next steps include testing whether a larger room affects brain processes we use in everyday life.

Well now you can cheer up, thanks to a new study validating the link between your cranky mood and grumbly belly – your ‘hanger’ is real.</p> <p>Psychologists studying a group of primarily Austrian, German and Swiss adults have found an association between self-reported hunger, and heightened levels of anger and irritability.</p> <p>Helping people understand their own emotional responses to feelings of hunger could help them better regulate their behaviour, says Anglia Ruskin University professor in social psychology Viren Swami.</p> <p>“Research suggests that being able to label an emotion can help people to regulate it,” says Swami, who was the lead author of the study <a href="https://doi.org/10.1371/journal.pone.0269629" target="_blank" rel="noreferrer noopener">published</a> in <em>Plos One</em>. “Therefore, greater awareness of being ‘hangry’ could reduce the likelihood that hunger results in negative emotions and behaviours in individuals.”</p> <p>The three-week study monitored 64 participants who submitted five daily reports to researchers via a smartphone app.</p> <p>In each report, participants used a 0–100 scale to evaluate how hungry, irritable and angry they felt.</p> <p>Even when accounting for demographic differences between participants, there was an association between hunger and heightened levels of irritability, anger and reduced feelings of pleasure.</p> <p>It’s the first time the phenomenon has been investigated outside of a laboratory environment and adds to an existing body of research showing that declines in blood glucose levels influences negative emotions.</p> <p>“This ‘hangry’ effect hasn’t been analysed in detail, so we chose a field-based approach where participants were invited to respond to prompts,” explains study co-author Stefan Stieger, professor of psychology at Karl Landsteiner University.</p> <p>“[It gives] a much more complete picture of how people experience the emotional outcomes of hunger in their everyday lives.”</p> <p>The researchers didn’t offer conclusions as to how to mitigate hunger-induced feelings. Reaching for a banana next time you feel cross is probably a safe bet.</p> <p><em>Image credits: Getty Images</em></p> <p><em><!-- Start of tracking content syndication.

The 6 best bath bomb recipes for every mood

<p><strong>Customise your bath bomb</strong></p> <p>Few natural remedies are as effective for hitting your internal reset button as a hot bath. By customising the bath bomb recipe below with a variety of essential oils, you can soothe everything from frayed nerves to achy muscles, says intergrative health expert Dr Tasneem Bhatia. Keep reading to see how.</p> <p><strong>Basic bath bomb recipe</strong></p> <p>Here’s what you’ll need:</p> <p>2 cups baking soda</p> <p>1 cup citric acid</p> <p>1/2 cup Epsom salt</p> <p>1 tablespoon almond or olive oil</p> <p>Essential oils</p> <p>Water</p> <p>Packing moulds (If you don’t have food moulds, ice cube trays, hollow plastic Easter eggs, or Christmas tree ornaments that snap open and closed will do.)</p> <p>Directions:</p> <p>Mix baking soda, citric acid and Epsom salt in a bowl. Add almond or olive oil and essential oils. Add water slowly (the mixture might create a small foaming reaction. If that happens, pour even more slowly). The mixture should be just moist enough to hold a shape. Pack mixture into moulds for a few minutes, then tap to release. Allow bath bombs to dry for about five hours. To use, simply drop one in the bath. Enjoy!</p> <p>Note: Bath bombs should be used within three weeks.</p> <p><strong>A bath bomb for when you’re feeling stressed</strong></p> <p>To soothe the senses when you’re stressed out, try a bath bomb infused with 10 drops of bergamot (use one labelled bergaptene-free) and 10 drops of clary sage. The citrusy-flower bergamot mixed with clary sage calms the nervous system and clears the mind.</p> <p>“Bergamot is an anti-inflammatory and antiseptic and its aromatic scent has been shown to reduce stress and anxiety,” says Dr Bhatia, echoing the findings of a review of studies published in 2019 in Food Science &amp; Nutrition. “Clary sage also reduces stress and acts as an antidepressant.”</p> <p><strong>A bath bomb for when you can’t fall asleep</strong></p> <p>Settle into a more restful state by creating a bath bomb that includes 10 drops of chamomile, 10 drops lavender and 10 drops mandarin.</p> <p>“Both lavender and chamomile are calm- and relaxation-promoting herbs, while mandarin is known to be calming and promote joy,” says Dr Bhatia.</p> <p><strong>A bath bomb for when your muscles ache</strong></p> <p>Soothe sore muscles with a bath bomb infused with 10 drops lavender and 10 drops rosemary, which reduces inflammation.</p> <p>“Lavender is calming, while rosemary is known to increase blood flow, helping muscle soreness,” says Dr Bhatia. For even more of a treat, add extra Epsom salt to your bath before you hop in. The magnesium sulfate works as a natural muscle relaxant, pulling fluid out of the muscles and reducing swelling.</p> <p><strong>A bath bomb for when you need a pick-me-up</strong></p> <p>Need a bath bomb to help you overcome that 3pm gotta-have-a-nap feeling on days you work from home? Add 10 drops grapefruit oil and 10 drops bergamot oil.</p> <p>Keep in mind: “Citrus oils can sting a bit so you have to be careful with them,” says Dr Bhatia. If the grapefruit-bergamot combo doesn’t do the trick, soak a cotton swab with peppermint essential oil and take a whiff whenever you need an extra zap of energy.</p> <p><strong>A bath bomb for setting a romantic mood</strong></p> <p>Floral scents like rose oil and ylang-ylang are great for setting the mood for romance, if only because “they’re soothing scents that promote calm and relaxation,” says Dr Bhatia.</p> <p>Try a bath bomb made with 10 drops of each. Add a pinch of vanilla for an added kick.</p> <p><strong>A bath bomb for indulging the senses</strong></p> <p>For an all-purpose bath bomb that will indulge the senses no matter the mood or the moment, try this fresh-floral mix: 10 drops rose or lavender oil, 10 drops of lemon and 5 drops of patchouli. “This is a combo of stress relief and a bit of a pick-me-up,” says Dr Bhatia. “Like many citrus oils, lemon is stimulating while patchouli and lavender are relaxing and provide skin relief.”</p> <p><em><span id="docs-internal-guid-56b0ac19-7fff-a1c7-12e7-b424249a4680">Written by Juliana LaBianca.

How nostalgic, happy thoughts make you healthier

<h2>Longing for the past can improve your health in a number of surprising ways</h2> <p>“Nostalgia has been shown to counteract loneliness, boredom and anxiety,” John Tierney wrote in a recent New York Times article. “It makes people more generous to strangers and tolerant of outsiders. Couples feel closer and look happier when they’re sharing nostalgic memories.” It may even make you literally warmer: feelings of nostalgia are more common on cold days, and people in cool rooms are more likely to reminisce than those in warmer ones, research shows. Why? It might be evolutionary: “If you can recruit a memory to maintain physiological comfort, it could contribute to survival by making you look for food and shelter that much longer,” researcher, Dr Tim Wildschut, told the Times. Here’s how to leverage your happy thoughts and warm memories to make yourself healthier.</p> <h2>Carve out time for reminiscing</h2> <p>Some 79 per cent of people naturally experience nostalgia at least once a week, research indicates, but you don’t have to wait for a chance memory to pop into your mind. Loyola University researchers discovered that thinking of good memories for just 20 minutes a day can make people more cheerful than they felt the week before, reported Psychology Today.  </p> <h2>Don’t write down your memories</h2> <p>To reap the full benefits of nostalgia, it seems better to replay happy thoughts in your mind rather than in a journal. When researchers at the University of California at Riverside asked people to either think about or write down a blissful life experience, those who simply thought about it experienced a greater boost in wellbeing, according to Psychology Today. “There’s a magic and mystery in positive events,” study author and psychologist, Dr Sonja Lyubomirsky, told the magazine. Analysing the details – by writing them down – may remove some of that wonder.</p> <h2>Focus on sound and smell to get there faster</h2> <p>Listening to music is a quick, easy way to induce nostalgia; researchers often use it in their studies, according to the Times. Think about the songs on the radio when you were growing up, for example. Scents, too, are powerful tools to unlock memories. Smells get to our brain faster than sights or sounds – particularly, to our emotional centres – according to neurologist, Dr Alan Hirsch.</p> <h2>Try not to compare the past to the present</h2> <p>Of course, not all old memories are positive ones; and looking back to happier times may make you feel anxious about where you are today. Recalling your academic successes in high school and university, for example, may make you feel like a has-been in your current job. It’s challenging, but experts recommend trying to focus on the memories alone, without comparing them to other events.</p> <h2>Think back with others</h2> <p>Reminiscing with friends and family strengthens close relationships, says Psychology Today. Look at old photos and videos during holiday get-togethers; reconnect with former school friends on social networks and revisit your shared memories.</p> <h2>Make experiences memorable</h2> <p>Nostalgia researcher, Dr Constantine Sedikides, calls this strategy “anticipatory nostalgia” – living your life cultivating experiences you’ll want to savour down the road. This ties into research that spending money on experiences, rather than things, tends to make people happier. So splurging on the hot-air balloon ride will go farther than the take-home souvenir.</p> <p><em><strong>This article originally appeared on <a href="https://www.readersdigest.com.au/culture/how-nostalgic-happy-thoughts-make-you-healthier" target="_blank" rel="noopener">Reader’s Digest</a>.</strong></em></p> <p><em>Image: Shutterstock</em></p>

Music is the soundtrack to your life – what’s on your playlist?

<p>We all know music can move us emotionally. But how does it impact on our behaviour? That relationship’s not immediately clear. </p> <p>A YouTube clip was doing the rounds on social media a while ago – the music from one of the most chilling scenes in the 1975 film <em>Jaws</em> had been quite cleverly changed. Instead of the <a href="https://www.youtube.com/watch?v=A9QTSyLwd4w">original hair-raising theme</a> that we all know by composer John Williams, the scene was accompanied by the delicate ballet music of Tchaikovsky. </p> <p>The effect was startling. It could have been a completely different film – one about a fun-loving dolphin. It’s a good example of what an incredibly powerful mood-setter music is. So many of our favourite films just wouldn’t have the same impact without the music.</p> <p>It’s the same outside of the cinema – a fact that has been instinctively understood by humans since written records began. In ancient China, more than 4,000 years ago, <a href="http://www.unboundmedicine.com/medline/citation/8402699/The_sick_child_and_music_">flute music was prescribed</a> to calm an over-excited foetus.</p> <p>The Egyptians also seemed to use music for therapeutic purposes at least as early as 1500 BC. Then there is the much-loved biblical tale of King Saul being soothed by the playing of David’s harp in the Old Testament.</p> <p>Today, we often use music to “get into” a mood – using soft music and lyrics to set the scene for romance which, as a seduction tactic, can be quite effective. <a href="http://pom.sagepub.com/content/38/3/303.refs">Researchers in France found</a> that women who were exposed to love songs were more likely to respond to a request for a date than those who were in a control group and did not hear this music.</p> <p>At other times, we may use a fast, up-tempo piece of music at the gym to get us working harder. Music has also been used across the centuries to <a href="http://vimeo.com/72609411">pump up soldiers in the face of battle</a>, the same energising facets of the music being drawn upon, in this context to promote aggression (see famous Wagner scene from <em>Apocalypse Now</em> (1979) below).</p> <p>So does that mean that music can be both good and bad for you? Potentially, yes. </p> <p>But music exists within a socio-cultural context and it is how the music interacts with other factors that produces a particular result. </p> <p>So, at the gym it is how and why the music is framed that helps to promote its invigorating qualities for the desired work-out ends. Where it could lead to aggression, there are contextual factors that influence the way in which it’s processed and in turn how it affects us.</p> <p>Recent anti-noise bans that <a href="https://theconversation.com/live-music-in-australia-offensive-noise-or-good-vibrations-13530">prevented live music being played</a> in many Australian pubs connected loud music with aggressive behaviour.</p> <p>The truth is that rock music might indeed encourage patrons to move faster, be more pumped up, and perhaps drink more, be less inhibited, louder, and so manifest a whole range of behaviours than might be regarded as anti-social, leading to an aggression response. But, these are not generated from the music itself, rather in the context and the alignment of many interacting factors.</p> <p>Perhaps the most useful way to reflect on the positives of music is that it can be part of a “healthy process of self-regulation” as American music therapist <a href="http://mtp.oxfordjournals.org/content/21/2/69.abstract">Bridget Doak says</a> and, when negative, it may be part of an “unhealthy, distress-addiction cycle”. </p> <p><a href="https://kb.osu.edu/dspace/bitstream/handle/1811/52950/EMR000125a-Garrido.pdf">Researchers have found</a> that people listen to sad music for a variety of reasons. Some may find that having a good cry while listening to a piece of music is a good way to let go of bad feelings. For others it may give them a chance to think through things that are making them feel sad in their own lives and reach a point of resolution. </p> <p>But some people do not have such effective ways of making themselves feel better. People with mood disorders, for example, often engage in behaviours that can make them feel worse, and music can be a part of that behaviour.</p> <p>Music can have such a powerful impact on mood. Whether or not our lives resemble a light-hearted ballet or a scene of terror in shark-infested waters may have much to do with the music that surrounds us on a daily basis. </p> <p><em>Image credits: Getty Images</em></p> <p><em>This article first appeared on <a href="https://theconversation.com/music-is-the-soundtrack-to-your-life-whats-on-your-playlist-26893" target="_blank" rel="noopener">The Conversation</a>. </em></p>

A million Aussies over 60 yet to have booster as cases tipped to rise

<p>With coronavirus cases in Australia seeing a steep uptick in recent days, state health ministers have warned over-60s to get their booster vaccine. </p> <p>Cases are expected to double in the coming weeks, with over 900,000 Aussies in the 60-plus age bracket yet to book in for the latest jab.</p> <p>NSW Health Minister Brad Hazzard has said he does not support reinstating pandemic lockdown restrictions, but is encouraging everyone to have their booster as soon as possible. </p> <p>“What we’ve seen in the last few years is that as soon as positive cases start going up, people start getting vaccinated. It would make a lot more sense if they got [boosted] now, so they are less likely to catch the virus and be part of those rising numbers,” Mr Hazzard said.</p> <p>NSW reported a dramatic increase in Covid cases on Wednesday, with 30,402 infections after a data glitch meant about 10,000 tests on Sunday and Monday failed to be added to daily case counts.</p> <p>Despite the data glitch, the sudden uptick in cases has health officials concerned that many people are getting complacent in their thoughts towards the virus. </p> <p>“Boosters are our passage to safety and normal life, go and get it, don’t muck around.”</p> <p>In NSW, more than 330,000 people over the age of 60 have yet to have the jab, as Mr Hazzard warned the vulnerable group to be protected. </p> <p>“We’ve got just over 300,000 people in the 60-plus age bracket who are still not boosted … that makes them particularly vulnerable. They’re the grandmothers and grandfathers, the aunts, the uncles that young people are going to see. We need the whole population boosted,” he said.</p> <p><em>Image credits: Getty Images</em></p>

Why millions of Aussies have not gotten boosters

<p>A new study has revealed that adults across Australia are proving very hesitant to receive their Covid-19 boosters.</p> <p>The analysis shows the hesitancy is not from vaccine misinformation or resistance, but from being completely disengaged from consuming further information about Covid-19.</p> <p>The survey conducted by the Australian National University shows less than half of all double vaccinated Australians aged 18 and over have had their booster.<br />It also found young Australians aged 18-24, Indigenous Australians, people with low education, and those who live in disadvantaged areas, are less likely to have received the third shot.</p> <p>In January, the ANU survey of more than 3400 adults found about four-in-10 Australians or 41.5% had received a third dose of a COVID-19 vaccine.</p> <p>Study co-author Nicholas Biddle says 65.4% of people surveyed confirmed they would definitely get a booster compared to 71.9% in a survey previously conducted in October.</p> <p>'The findings suggest that booster uptake is not due to active resistance ... but rather because people either do not have that much information about the need for a third dose or because they have made a judgement that it is not necessary for them,' he said.</p> <p>'The experience of the first two doses, particularly side effects, may also have made some reluctant to seek out a third dose.'</p> <p>Although Australia had high success nationally with the initial rollout, where 94.4% of people over 16 years have had two doses, the ANU analysis shows there is no guarantee that success will be repeated in the booster rollout.</p> <p>'There is a very large proportion of adult Australians who are eligible for a booster but have not yet done so, with many of these individuals likely to have waning immunity from their first two doses,' Professor Biddle said.</p> <p>This information coincides with the restrictions lifting, where wearing a mask and checking in will become a thing of the past. Nationally, more than 25,000 COVID-19 infections were recorded on Thursday. </p> <p><em>Image: Getty </em></p>

13 tiny changes that will make your home instantly happier

<p><strong>Keep clutter minimal</strong></p><p>A stack of books. A pile of papers. Knick-knacks everywhere! If objects are crowding every surface of your home, you’re not alone. The first step to being truly happy in your space is to figure out what to keep, and what to let go. “A cluttered room is much more likely to produce, and contribute to, a cluttered mind,” says professional organiser Marie Kondo, author of the bestseller <em>The Life-Changing Magic of Tidying Up</em>. “I believe that only in an uncluttered room, which enables an uncluttered mind, can you truly focus your attention and your energy on the matters in your life which are preventing you from reaching your truest happiness.”</p><p>According to design psychologist Sally Augustin, the powerful mental effects of clutter have roots in our evolution. “In our early days as a species, our lives depended on continually surveying the environment and seeing if anything was going to eat us,” she says. “Today we continue to survey our environment, and too many things make this subconscious reviewing more difficult, which is why the visual complexity of clutter is so stressful.” A study from Princeton University shows that too much disorganised stimuli simply overwhelms the brain.</p><p><strong>Display meaningful objects</strong></p><p>The process of letting go of ‘stuff’ doesn’t mean you should live in a stark environment, according to Dr Augustin that would feel alien to us. Kondo’s method uses the test of whether an object ‘sparks joy’ in your heart. “When you decide what to keep based on what sparks joy, you are establishing and reaffirming to yourself what is most important to you,” she says. It’s not about the latest home design styles, it’s how an object makes you feel.</p><p>Still love showing off that soccer trophy from third grade? Keep it! As far as how much to display, balance out the chaos in your life with a visually quieter environment. The amount that feels right may vary from person to person, but Dr Augustin suggests four or five pictures in a room and a couple of objects on a surface, depending on the size. Kondo says an added benefit of going through your possessions is learning how to get rid of mental baggage as well as the physical. “The skills you learn can be applied in your life well beyond deciding on which souvenir coffee mug to keep,” she says.</p><p><strong>Create a calming space</strong></p><p>Finding a ‘sanctuary’ in your home gives your mind a place to go to rest and restore, helping you feel more at peace. It doesn’t have to be a whole room, it could be a reading nook, a knitting or craft space, or even a ‘home spa’ in your bathroom. </p><p>In carving out your sacred space, Dr Augustin suggests bright but muted colours like sage, soft textures like flannel, warm light, and curved lines in patterns and objects instead of straight lines. Studies show we prefer curved lines because we see sharp transitions, such as right angles, as more of a threat.</p><p><strong>Bring nature inside</strong></p><p>Studies have shown nature to be calming to our psyche, so one way to feel happier in your space is to bring plants inside. “Bringing nature into your home definitely has powerful psychological effects,” says interior designer and design psychology coach <a href="http://www.happystartsathome.com/">Rebecca West</a>. “Peace lilies are one of my favourites because they’re easy-to-care-for and do well in low light conditions.” Dr Augustin also suggests avoiding spiky plants.</p><p>“We associate comfort with curvy shapes and not spiky ones, which make us more alert,” she says. Houseplants have the added benefit of helping to refresh the air in a room, making you healthier, according to research. “But if you aren’t blessed with a green thumb, then fresh flowers or even a print of a garden or a wall mural of trees can affect some of that same profound healing,” West says. “Even having natural wood furniture in your home partnered with green accessories or wall paint can bring that outdoor feeling inside.”</p><p><strong>Make your space more social</strong></p><p>Humans are pro-social beings, so your home should also be a place where you feel comfortable inviting friends over. Consider buying home items that lend themselves to socialising: a barbecue, a fire pit to gather around, or board games for game night. Plus, make sure your rooms are arranged for easy socialising. “If you want your living room to be ready for a book club, then it should be arranged to focus on conversation, not a giant TV,” West says. Dr Augustin suggests considering your guests’ varying personalities as well.</p><p>“Extroverts would prefer couches and introverts would prefer an individual chair, so you should have a range of options,” she says. “Arrange the furniture so people can make easy eye contact with each other, but also so they can gracefully break eye contact and look at something else, like a fish tank, a piece of art, or a window with a view.” These ‘positive distractions’ can help you and your guests adhere to humans’ preferred length of eye contact; about three seconds, according to <a href="http://rsos.royalsocietypublishing.org/content/3/7/160086">research</a>.</p><p><strong>Use light well</strong></p><p>Psychologists have long known that light has an effect on our emotions. So when choosing what kind of light to have in your home, think about what feelings you’re trying to elicit in the space. “Warm light with warm light bulbs is better for when you’re socialising and relaxing, where blue and cooler light is better when you’re trying to do a really analytic task,” Dr Augustin says. So cool light might be better for a home office, but use warm light in the living and dining rooms.</p><p>“When people are having dinner parties they bring in candles, which are a warmer light – something we figured out eons ago which aligns with <a href="http://www.ledinside.com/knowledge/2013/12/lighting_psychology_cognitive_and_emotional_responses_to_lighting">modern research</a>,” she says. During the day, open the curtains and keep the windows clean to let the sun in. “Natural light is great for our mood,” Dr Augustin says. “But if a space is really glarey because you have lots of shiny surfaces, some of the positive ramifications of daylight evaporate because glare is stressful.”</p><p><strong>Keep it clean</strong></p><p>Having a clean home can have physical as well as mental benefits – less stuff means fewer things for dust and dirt to accumulate on, and you’ll be more likely to keep it clean because it won’t be so overwhelming. “The less clutter there is in your home, the easier it is to do basic cleaning chores, which let’s be honest, spark joy in almost nobody!”</p><p>Kondo says. Instead, you can use the time you save to do other things you enjoy more. But sometimes, a good cleaning can actually help you feel less stressed and anxious. “If you find yourself feeling frantic and overwhelmed, taking a moment to tidy up the kitchen or your bed can really calm those nerves and bring more focus into your mind,” West says.</p><p><strong>Make the bedroom a retreat</strong></p><p>Our mood improves when we wake up ‘on the right side of the bed’ after a good night’s sleep, and not getting good sleep has been <a href="https://sleepfoundation.org/sleep-disorders-problems/depression-and-sleep">linked to depression</a>. One way to feel more relaxed is to banish any reminders of unpleasant tasks in the bedroom. “If you have your home office in your bedroom, it’s great if the room is laid out so that when you’re actually lying down to go to sleep you don’t see your desk and all the piles of papers,” Dr Augustin says. Ideally, the bedroom should be one space to keep tidy.</p><p>“If you can’t put your whole home in order, try to have at least one room, such as the master bedroom, that gives you peace and respite from it all,” West says. Blackout curtains can also ensure the room is dark enough for good sleep. “It’s better for our health when the conditions are darker for sleep,” Dr Augustin says. “You can pull them during the day to let the daylight in.”</p><p><strong>Find storage solutions that work</strong></p><p>Even if your living spaces are clean, if every time you open that cupboard you’re pegged with an avalanche of stuff, it will still make you feel bogged down. “Simple storage methods are the best because they are the easiest to maintain,” says Kondo, who prefers shoe boxes. “Some people devise their storage strategies like a ‘Jenga’ tower, and we all know what happens when one piece is removed!”</p><p>Plus, being able to see everything you have also keeps you from buying new stuff you actually don’t need. If everything is simple and easy to access, it becomes not only routine, but a healthy habit, Kondo says. “You will always find ‘that thing’ you are looking for much easier, and that extra 10 or 15 minutes you save can be used to do something you truly enjoy.”</p><p><strong>Choose mood-boosting colours</strong></p><p>Your wall colour can affect your mood, so it might be time for a new coat of paint. Colour psychology is an entire field dedicated to understanding the impact shades have on us. “It’s the saturation and brightness levels of hues that determine our emotional response,” Dr Augustin says. “We’re calmer and in a more positive mood in colours that are not too saturated but relatively bright like sage green, and we’re more energised around colours that are more saturated and less bright, like a Kelly green [an intense, pure green].”</p><p>Energising colours make you happier in a place you work, like a kitchen, laundry or exercise room, whereas muted colours are better for a relaxing space, like a family room. Certain colours are associated culturally as well, which can help us feel at home in the space. “Our culture links yellow with kitchens and blue with restfulness, a good option for bedrooms,” Dr Augustin says.</p><p><strong>Use the power of scent</strong></p><p><a href="https://academic.oup.com/chemse/article/30/suppl_1/i248/270387/Effects-of-Fragrance-on-Emotions-Moods-and">Studies have shown</a> smell has psychological effects, so use oils or candles to evoke good feelings in your home. “Researchers have learnt that lavender helps people fall asleep so that can be good for the bedroom, and lemon can be good to smell when you’re trying to do cognitive work like in your home office,” Dr Augustin says.</p><p>Floral scents also elicit positive emotions. But don’t lay it on too strong – scents will continue to have an effect even after your nose gets used to them. “Any smell in too great a concentration is off-putting and stress-generating,” she says.</p><p><strong>Fill your home with good memories</strong></p><p>Let everything in your house bring up positive memories of things and people you love. “Each time you look at that picture of you and your friends in Paris, or see the painting you did that turned out better than you ever expected, it helps you keep perspective and connect you with what is good and wonderful in your life,” West says.</p><p>On the other hand, purge the things that remind you of negative experiences and bring you down. “A stuffed animal from an ex-boyfriend, or a piece of furniture that you inherited but have never really liked, can keep you stuck in the past,” she says. “Life is too short to be surrounded by stuff you don’t like.”</p><p><em>Image credits: Getty Images</em></p><p><em>This article originally appeared on <a href="https://www.readersdigest.com.au/food-home-garden/home-tips/13-tiny-changes-that-will-make-your-home-instantly-happier?pages=1" target="_blank" rel="noopener">Reader's Digest</a>.</em></p>
