"We're giving them weapons": Charlotte O'Brien's parents call for social media ban

The parents of a young girl who took her own life after being bullied have joined a campaign to raise the age limit for social media. Charlotte O'Brien was a student at Santa Sabina College in Sydney’s inner west, where she dealt with relentless bullying which led to the 12-year-old's tragic death. Now, her parents Mat Howard and Kelly O’Brien appeared on 60 Minutes to ask “how many more Charlottes do we need to lose” before action was taken to protect kids from harm online. When asked if she believed Charlotte would still be alive if social media was off limits to young children, Ms O’Brien replied: “Absolutely”. “My personal opinion. Giving our kids these phones, we’re giving them weapons, we’re giving them the world at their fingertips,” the grieving mother said. In the days after the young girl's death, it was revealed her parents had pleaded with her school to address “friendship issues” Charlotte was facing. Mr Howard told 60 Minutes that despite her “ongoing struggles” the last two weeks of Charlotte’s life were “the best two weeks that I can remember with her”, adding, "We thought we were really turning the corner.” “You know she’d come home from school that day and she’d had a great day. Kelly had made her favourite dinner that night. And that night she skipped off to bed, literally skipped. And we never saw her again.” Her family revealed a “completely distressed” Charlotte spoke to a friend on her phone the night she died, and shared messages she had been sent online. “So we can’t say exactly what we’ve been told, but what I will tell you is what we’ve been told is some of the worst words that anybody should have to read, let alone a 12-year-old girl,” Mr Howard said. Recalling the heart-wrenching moment they found their daughter's body, Ms O'Brien said she pleaded for answers from police on how she would've taken her own life. “I just kept saying to the police that morning, ‘Where did she get the knowledge and the means? Where did she get the knowledge and the means?’,” she said. “I couldn’t wrap my head around it, and he (the police officer) just said to me, ‘This is the age of information. She just needed to Google it’. And for me, I’m so devastated by that because I gave her that phone.” Charlotte’s parents have travelled to Canberra to meet with Prime Minister Anthony Albanese, ahead of legislation to raise the age of using social media from 13 to 16. “I intend to say, ‘Please, Mr. Albanese, raise the age of social media to 16, because 36 months could change a lifetime’. That’s what I’m going to say,” Ms O’Brien said. Mr Howard said, “Charlotte was not the first and she’s already not the last. And this will continue to happen unless we make the right decisions.” The controversial bill to raise the age on social media platforms is set to go before Australia’s federal parliament this week, with support from both major parties.

Caring

These 12 things can reduce your dementia risk – but many Australians don’t know them all

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/joyce-siette-1377445">Joyce Siette</a>, <a href="https://theconversation.com/institutions/western-sydney-university-1092">Western Sydney University</a> and <a href="https://theconversation.com/profiles/laura-dodds-1378067">Laura Dodds</a>, <a href="https://theconversation.com/institutions/western-sydney-university-1092">Western Sydney University</a> Dementia is a <a href="https://www.abs.gov.au/statistics/health/causes-death/provisional-mortality-statistics/jan-may-2022">leading</a> cause of death in Australia. Although dementia mainly affects older people, it is an avoidable part of ageing. In fact, we all have the power to reduce our risk of developing dementia, no matter your age. Research shows your risk of developing dementia could be <a href="https://www.thelancet.com/article/S0140-6736(20)30367-6/fulltext">reduced by up to 40%</a> (and even higher if you live in a <a href="https://www.thelancet.com/journals/langlo/article/PIIS2214-109X(19)30074-9/fulltext">low or middle-income country</a>) by addressing lifestyle factors such as healthy diet, exercise and alcohol consumption. But the first step to reducing population-wide dementia risk is to understand how well people understand the risk factors and the barriers they may face to making lifestyle changes. Our new <a href="https://www.mdpi.com/2673-9259/2/4/21/htm">paper</a>, published this week in the <a href="https://www.mdpi.com/2673-9259/2/4/21/htm">Journal of Ageing and Longevity</a>, found most older people are aware that dementia is a modifiable condition and that they have the power to change their dementia risk. We also found the key barrier to making brain healthy lifestyle choices was a lack of knowledge, which suggests a public awareness campaign is urgently needed. <h2>What we did</h2> We began by <a href="https://www.mdpi.com/2673-9259/2/4/21/htm">reviewing</a> the published research to identify 12 factors shown to reduce dementia risk. We surveyed 834 older Australians about their awareness of the 12 factors, which were: <ol> <li>having a mentally active lifestyle</li> <li>doing physical activity</li> <li>having a healthy diet</li> <li>having strong mental health</li> <li>not smoking</li> <li>not consuming alcohol</li> <li>controlling high blood pressure</li> <li>maintaining a healthy weight</li> <li>managing high cholesterol</li> <li>preventing heart disease</li> <li>not having kidney disease</li> <li>not having diabetes</li> </ol> <a href="https://www.thelancet.com/article/S0140-6736(20)30367-6/fulltext">The Lancet</a> subsequently published its own list of factors that help reduce dementia risk, which covered much the same territory (but included a few others, such as reducing air pollution, treating hearing impairment and being socially engaged). Of course, there is no way to cut your dementia risk to zero. Some people do all the “right” things and still get dementia. But there is <a href="https://www.thelancet.com/article/S0140-6736(20)30367-6/fulltext">good evidence</a> managing lifestyle factors help make it less likely you will get dementia over your lifetime. Our study shows many older Australians are quite aware, with over 75% able to correctly identify more than four of the factors in our list of 12. However, few were able to name the less well-known risk factors, such as preventing heart disease and health conditions like kidney disease. The good news is that close to half of the sample correctly identified more than six of the 12 protective factors, with mentally active lifestyle, physical activity and healthy diet in the top three spots. <h2>Two key issues</h2> Two things stood out as strongly linked with the ability to identify factors influencing dementia risk. Education was key. People who received more than 12 years of formal schooling were more likely to agree that dementia was a modifiable condition. We are first exposed to health management in our school years and thus more likely to form healthier habits. Age was the other key factor. Younger respondents (less than 75 years old) were able to accurately identify more protective factors compared to older respondents. This is why health promotion initiatives and public education efforts about dementia are vital (such as Dementia Awareness Month and <a href="https://www.memorywalk.com.au/">Memory, Walk and Jog initiatives</a>). <h2>How can these findings be used in practice?</h2> Our findings suggest we need to target education across the different age groups, from children to older Australians. This could involve a <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/ajag.13049">whole system approach</a>, from programs targeted at <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5858574/#:%7E:text=Family%20Coaching%20has%20specific%20goals,to%20problem%20solve%20challenging%20situations.">families</a>, to educational sessions for school-aged children, to involving GPs in awareness promotion. We also need to tackle barriers that hinder dementia risk reduction. This means doing activities that motivate you, finding programs that suit your needs and schedule, and are accessible. <h2>What does this mean for you?</h2> Reducing your dementia risk means recognising change starts with you. We are all familiar with the everyday challenges that stop us from starting an exercise program or sticking to a meal plan. There are simple and easy changes we can begin with. Our team has developed a program that can help. We are offering limited <a href="https://www.brainbootcamp.com.au/">free brain health boxes</a>, which include information resources and physical items such as a pedometer. These boxes aim to help rural Australians aged 55 years and over to adopt lifestyle changes that support healthy brain ageing.

Your friend has been diagnosed with cancer. Here are 6 things you can do to support them

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/stephanie-cowdery-2217734">Stephanie Cowdery</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>; <a href="https://theconversation.com/profiles/anna-ugalde-2232654">Anna Ugalde</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>; <a href="https://theconversation.com/profiles/trish-livingston-163686">Trish Livingston</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>, and <a href="https://theconversation.com/profiles/victoria-white-1888110">Victoria White</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> Across the world, <a href="https://www.who.int/news/item/01-02-2024-global-cancer-burden-growing--amidst-mounting-need-for-services">one in five</a> people are diagnosed with cancer during their lifetime. By age 85, almost <a href="https://www.cancer.org.au/cancer-information/what-is-cancer/facts-and-figures">one in two</a> Australians will be diagnosed with cancer. When it happens to someone you care about, it can be hard to know what to say or how to help them. But providing the right support to a friend can make all the difference as they face the emotional and physical challenges of a new diagnosis and treatment. Here are six ways to offer meaningful support to a friend who has been diagnosed with cancer. <h2>1. Recognise and respond to emotions</h2> When facing a cancer diagnosis and treatment, it’s normal to experience a range of <a href="https://www.canceraustralia.gov.au/impacted-by-cancer/emotions#:%7E:text=It's%20likely%20that%20feelings%20will,these%20feelings%20ease%20with%20time">emotions</a> including fear, anger, grief and sadness. Your friend’s moods may fluctuate. It is also common for feelings to <a href="https://link.springer.com/article/10.1007/s00520-014-2492-9">change over time</a>, for example your friend’s anxiety may decrease, but they may feel more depressed. Some friends may want to share details while others will prefer privacy. Always ask permission to raise sensitive topics (such as changes in physical appearance or their thoughts regarding fears and anxiety) and don’t make assumptions. It’s OK to tell them you feel awkward, as this acknowledges the challenging situation they are facing. When they feel comfortable to talk, follow their lead. Your support and willingness <a href="https://www.cancervic.org.au/get-support/stories/what-to-say-and-not-say.html">to listen without judgement</a> can provide great comfort. You don’t have to have the answers. Simply acknowledging what has been said, providing your full attention and being present for them will be a great help. <h2>2. Understand their diagnosis and treatment</h2> <a href="https://onlinelibrary.wiley.com/doi/full/10.1002/pon.4722">Understanding</a> your friend’s diagnosis and what they’ll go through when being <a href="https://www.cancer.org/cancer/caregivers/what-a-caregiver-does/treatment-timeline.html">treated</a> may be helpful. Being informed can reduce your own worry. It may also help you to listen better and reduce the amount of explaining your friend has to do, especially when they’re tired or overwhelmed. Explore reputable sources such as the <a href="https://www.cancer.org.au/">Cancer Council website</a> for accurate information, so you can have meaningful conversations. But keep in mind your friend has a trusted medical team to offer personalised and accurate advice. <h2>3. Check in regularly</h2> Cancer treatment can be isolating, so regular check-ins, texts, calls or visits can help your friend feel less alone. Having a normal conversation and sharing a joke can be very welcome. But everyone copes with cancer differently. Be patient and flexible in your support – some days will be harder for them than others. Remembering key dates – such as the next round of chemotherapy – can help your friend feel supported. Celebrating milestones, including the end of treatment or anniversary dates, may boost morale and remind your friend of positive moments in their cancer journey. Always ask if it’s a good time to visit, as your friend’s immune system <a href="https://www.cancerresearchuk.org/about-cancer/what-is-cancer/body-systems-and-cancer/the-immune-system-and-cancer#:%7E:text=to%20fight%20cancer-,Cancer%20and%20treatments%20may%20weaken%20immunity,high%20dose%20of%20steroids">may be compromised</a> by their cancer or treatments such as chemotherapy or radiotherapy. If you’re feeling unwell, it’s best to postpone visits – but they may still appreciate a call or text. <h2>4. Offer practical support</h2> Sometimes the best way to show your care is through practical support. There may be different ways to offer help, and what your friend needs might change at the beginning, during and after treatment. For example, you could offer to pick up prescriptions, drive them to appointments so they have transport and company to debrief, or wait with them at appointments. Meals will always be welcome. However it’s important to remember cancer and its treatments may <a href="https://www.cancer.gov/about-cancer/treatment/side-effects/nutrition#effects-of-cancer-treatment-on-nutrition">affect</a> taste, smell and appetite, as well as your friend’s ability to eat enough or absorb nutrients. You may want to check first if there are particular foods they like. <a href="https://www.cancervic.org.au/downloads/resources/booklets/nutrition-cancer.pdf">Good nutrition</a> can help boost their strength while dealing with the side effects of treatment. There may also be family responsibilities you can help with, for example, babysitting kids, grocery shopping or taking care of pets. <h2>5. Explore supports together</h2> Studies <a href="https://pubmed.ncbi.nlm.nih.gov/35834503/">have shown</a> mindfulness practices can be an effective way for people to manage anxiety associated with a cancer diagnosis and its treatment. If this is something your friend is interested in, it may be enjoyable to explore classes (either online or in-person) together. You may also be able to help your friend connect with organisations that provide emotional and practical help, such as the Cancer Council’s <a href="https://www.cancer.org.au/support-and-services/cancer-council-13-11-20">support line</a>, which offers free, confidential information and support for anyone affected by cancer, including family, friends and carers. <a href="https://www.researchgate.net/publication/5659099_Systematic_review_of_peer-support_programs_for_people_with_cancer">Peer support groups</a> can also reduce your friend’s feelings of isolation and foster shared understanding and empathy with people who’ve gone through a similar experience. GPs <a href="https://pubmed.ncbi.nlm.nih.gov/34333571/">can help</a> with referrals to support programs. <h2>6. Stick with them</h2> Be committed. Many people feel <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC11120751/">isolated</a> after their treatment. This may be because regular appointments have reduced or stopped – which can feel like losing a safety net – or because their relationships with others have changed. Your friend may also experience emotions such as worry, lack of confidence and uncertainty as they adjust to a <a href="https://www.cancer.gov/about-cancer/coping/survivorship/new-normal">new way of living</a> after their treatment has ended. This will be an important time to support your friend. But don’t forget: looking after <a href="https://www.healthdirect.gov.au/caring-for-someone-with-cancer">yourself</a> is important too. Making sure you eat well, sleep, exercise and have emotional support will help steady you through what may be a challenging time for you, as well as the friend you love. <a href="https://www.deakin.edu.au/faculty-of-health/research/cancer-carer-hub">Our research</a> team is developing new programs and resources to support carers of people who live with cancer. While it can be a challenging experience, it can also be immensely rewarding, and your small acts of kindness can make a big difference.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/239844/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/stephanie-cowdery-2217734">Stephanie Cowdery</a>, Research Fellow, Carer Hub: A Centre of Excellence in Cancer Carer Research, Translation and Impact, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>; <a href="https://theconversation.com/profiles/anna-ugalde-2232654">Anna Ugalde</a>, Associate Professor & Victorian Cancer Agency Fellow, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>; <a href="https://theconversation.com/profiles/trish-livingston-163686">Trish Livingston</a>, Distinguished Professor & Director of Special Projects, Faculty of Health, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>, and <a href="https://theconversation.com/profiles/victoria-white-1888110">Victoria White</a>, Professor of Pyscho-Oncology, School of Psychology, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Caring

What are house dust mites and how do I know if I’m allergic to them?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/deryn-lee-thompson-1449312">Deryn Lee Thompson</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> People often believe they are allergic to <a href="https://ahd.csiro.au/everything-in-our-homes-gathers-dust-but-what-exactly-is-it-where-does-it-come-from-and-why-does-it-keep-coming-back-is-it-from-outside-is-it-fibres-from-our-clothes-and-cells-from-our-skin/">house dust</a>. But of the <a href="https://www.allergy.org.au/patients/allergy-treatments/allergen-minimisation">20% of Australians</a> suffereing with allergies, a number are are actually allergic to microscopic <a href="https://www.healthdirect.gov.au/dust-mites">house dust mites</a>. House dust mites belong to the same family as spiders and ticks. They measure just 0.2-0.3 mm, with 50 fitting on a single pinhead. They <a href="https://www.intechopen.com/chapters/71977">live</a> for 65–100 days, and females lay 60–100 eggs in their life. House dust mites love temperate climates and humidity. They feed off the skin cells we and animals shed, as well as mould, which they digest using special enzymes. These enzymes are excreted in their poo about <a href="https://www.intechopen.com/chapters/71977">20 times a day</a>. They also shed fragments of their exoskeletons. All these fragments trigger allergies in people with this type of allergic rhinitis (which is also known as hay fever) <h2>What are the symptoms?</h2> When people with house dust mite allergy inhale the allergens, they penetrate the mucous membranes of the airways and eyes. Their body recognises the allergens as a threat, releasing chemicals including one called histamine. This causes symptoms including a runny nose, an itchy nose, eyes and throat, sneezing, coughing and a feeling of mucus at the back of your throat (known as a post-nasal drip). People with this type of allergy usually mouth breath, snore, rub their nose constantly (creating a nasal crease called the “dust mite salute”) and have dark shadows under their eyes. House dust mite allergy <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7328274/">can also cause</a> poor sleep, constant tiredness, reduced concentration at work or school and lower quality of life. For people with eczema, their damaged skin barrier can allow house dust mite proteins in. This prompts immune cells in the skin to <a href="https://academic.oup.com/bjd/article/190/1/e5/7485663">release chemicals</a> which make already flared skin become redder, sorer and itchier, especially in children. Symptoms of house dust mite allergy occur year round, and are often worse after going to bed and when waking in the morning. But people with house dust mite allergy and pollen allergies find their year-round symptoms worsen in spring. <h2>How is it diagnosed?</h2> House dust mite allergy symptoms often build up over months, or even years before people seek help. But an accurate diagnosis means you can not only access the right treatment – it’s also vital for minimising exposure. Doctor and nurse practitioners can order a <a href="https://www.allergy.org.au/patients/allergy-treatments/allergen-minimisation">blood test</a> to check for house dust mite allergy. Alternatively, health care providers with <a href="https://www.allergy.org.au/hp/a-career-in-clinical-immunology-and-allergy">specialised allergy training</a> can perform skin prick tests. This involves placing drops of the allergens on the arm, along with a positive and negative “control”. After 15 minutes, those who test positive will have developed a mosquito bite-like mark. <h2>How is it treated?</h2> Medication options include one or a combination of: <ul> <li>daily non-sedating antihistamines</li> <li>a steroid nasal spray</li> <li>allergy eye drops.</li> </ul> Your health care professional will work with you to develop a <a href="https://www.allergy.org.au/images/stories/pospapers/ar/ASCIA_HP_Allergic_Rhinitis_2022.pdf">rhinitis (hay fever) medical management plan</a> to reduce your symptoms. If you’re using a nasal spray, your health provider will <a href="https://www.youtube.com/watch?v=_ytYj1TLojM">show you how to use it</a>, as people often use it incorrectly. If you also have <a href="https://www.nationalasthma.org.au/understanding-asthma/how-is-asthma-managed">asthma</a> or eczema which is worsened by dust mites, your health provider will adapt your <a href="https://www.nationalasthma.org.au/health-professionals/asthma-action-plans">asthma action plan</a> or <a href="https://medcast.com.au/qhub/eczema/resources">eczema care plan</a> accordingly. If you experience severe symptoms, a longer-term option is <a href="https://www.allergy.org.au/images/pc/ASCIA_PC_Allergen_Immunotherapy_FAQ_2024.pdf">immunotherapy</a>. This aims to gradually turn off your immune system’s ability to recognise house dust mites as a harmful allergen. Immunotherapy involves taking either a daily sublingual tablet, under the tongue, or a series of injections. Injections require monthly attendances over three years, after the initial weekly build-up phase. These are <a href="https://theconversation.com/im-considering-allergen-immunotherapy-for-my-hay-fever-what-do-i-need-to-know-190408">effective</a>, but are costly (as well as time-consuming). So it’s important to weigh up the potential benefits and downsides with your health-care provider. <h2>How can you minimise house dust mites?</h2> There are also important allergy minimisation measures you can take to reduce allergens in your home. Each week, <a href="https://www.allergy.org.au/component/finder/search?q=minimisation&Itemid=100001">wash</a> your bedding and pyjamas in hot water (over 60°C). This <a href="https://www.nationalasthma.org.au/living-with-asthma/resources/patients-carers/factsheets/dust-mites-trigger-my-asthma">removes</a> house dust mite eggs and debris. Opt for doonas, covers or quilts that can be washed in hot water above 60°C. Alternatively, low-cost waterproof or leak proof covers can keep house dust mites out. If you can, favour blinds and wood floors over curtains and carpet. Dust blinds and surfaces with a damp cloth each week and vacuum while wearing a mask, or have someone else do it, as house dust mites can become airborne during cleaning. But beware of costly products with big marketing budgets and little evidence to support their use. A new mattress, for example, will always be house dust mite-free. But once slept on, the house dust mite life cycle can start. Mattress protectors and toppers commonly claim to be “hypoallergenic”, “anti-allergy” or “allergy free”. But their pore sizes are not small enough to keep house dust mites and their poo out, or shed skin going through. Sprays claiming to kill mites require so much spray to penetrate the product that it’s likely to become wet, may smell like the spray and, unless dried properly, may grow mould. Finally, claims that expensive vacuum cleaners can extract all the house dust mites are unsubstantiated.

Mother and son reunited after rigid aged care rules divided them

An elderly woman and her disabled son are celebrating after they successfully beat a bureaucratic blockage that threatened to <a href="https://oversixty.com.au/lifestyle/family-pets/red-tape-threatens-to-remove-a-man-with-down-s-syndrome-from-his-elderly-mother" target="_blank" rel="noopener">split</a> them up for good. Anne Deans, 81, and her 56-year-old son, Mark, who suffers from Down's syndrome, were hoping to live together in Anne's aged care facility, but the pair were met with countless hurdles when trying to get Mark a room of his own. Now, Mark's sister Sharon shared the happy news that the mother and son are to be reunited. "We're very happy today.

"I'm so grateful that people understood and they listened. That's all I ever wanted through this whole thing, was someone to listen." The problems began when authorities originally refused Mark's request to move into Anne's aged care facility, with federal government policy saying that aged care is "not appropriate for people under 65". But Mark's relatives argued that given the life expectancy of people living with Down's syndrome is 60 years, an exception should be made. A new assessment was done and Mark has been granted a place at the same nursing home as his mother, as Mark's other sister Michelle said, "We got what we wanted. Everything worked out perfectly, the way it's supposed to." After Anne received the exciting news, she said, "I'm feeling great. He's staying with Mum!" Sharon and Michelle hope that their experience will assist other families with unique circumstances. "My advice is to keep pushing," Sharon said. "Only you know your family and you have to be their voice. "There's a lot of difference out there and a lot of people who are individuals [and] they need to be looked at individually."

Grave cleaning videos are going viral on TikTok. Are they honouring the dead, or exploiting them?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/edith-jennifer-hill-1018412">Edith Jennifer Hill</a>, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a> and <a href="https://theconversation.com/profiles/marina-deller-947925">Marina Deller</a>, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a> Cleaning the graves of strangers is the latest content trend taking over TikTok. But as millions tune in to watch the videos, it’s becoming clear not all of them are created equal. Two grave-cleaning creators in particular seem to reside at opposite ends of the trend. One of the first accounts to gain popularity for grave cleaning was <a href="https://www.tiktok.com/@ladytaphos">@ladytaphos</a>. This account is run by Alicia Williams, a Virginia resident who treats the graves with great dignity. Williams will often share the story of the person residing within, and acts with grace and kindness as she restores beauty to the <a href="https://www.tiktok.com/@ladytaphos/video/7197894295641148714">graves</a>. On the other end of the spectrum is Kaeli Mae McEwen, or <a href="https://www.tiktok.com/@_the_clean_girl">@the_clean_girl</a>, who leans into more clickbait-y tactics. McEwen is known for throwing a pink spiky ball through a graveyard and cleaning the grave it lands on. She also uses her videos to promote her own pink foamy cleaner (which at one point could be purchased via a link in her bio). <h2>Cleaning and death</h2> While Williams’ and McEwen’s videos may seem novel to some, death and cleaning have a long and varied relationship that spans time and cultures. Washing a loved one’s body before burial or cremation isn’t just practical – it’s a significant <a href="https://www.theage.com.au/national/victoria/washing-and-dressing-our-dead-the-movement-challenging-how-we-grieve-20230510-p5d794.html">ritual</a> that provides meaning during a period of grief. In certain cultures and religions it’s also a process of purification, or preparation for the afterlife. Much has been written about cleaning and clearing out the homes of deceased people. Family members often won’t agree on how to approach such a task. In his <a href="https://theconversation.com/friday-essay-grief-and-things-of-stone-wood-and-wool-136721">essay on death and objects</a>, author Tony Birch writes about his mother clearing out his grandmother’s house. “My mother decided that our first task after her death was to empty out her Housing Commission flat and scrub it clean,” Birch writes. He first laments the move, but later recognises the value of cleaning together before sorting – and treasuring – the items his grandmother left behind. Margaretta Magnuson’s 2017 book, <a href="https://www.google.com.au/books/edition/The_Gentle_Art_of_Swedish_Death_Cleaning/uW00DwAAQBAJ?hl=en&gbpv=1&pg=PT7&printsec=frontcover">The Gentle Art of Swedish Death Cleaning</a>, is a humorous and thoughtful introduction to the Swedish movement of döstädning. The book (and subsequent <a href="https://www.sbs.com.au/ondemand/tv-series/the-gentle-art-of-swedish-death-cleaning">reality TV series</a>) has sparked various conversations on death and cleaning, and especially on cleaning before you yourself pass away so you don’t leave a mess for your loved ones. Grave cleaning can be seen as another continuation of caring for the deceased. People who decide to clean the graves of strangers may do so out of <a href="https://www.theguardian.com/society/2022/sep/04/how-gravetok-videos-of-cleaning-headstones-went-viral">respect</a>, or in an attempt to <a href="https://www.buzzfeed.com/alexalisitza/tiktok-woman-cleans-old-gravestones">give them “their name back”</a> (as names on graves become visible following the removal of debris). <h2>Two very different approaches</h2> Williams and McEwen are received quite differently by viewers. Anecdotally, viewers respond more positively to the calmer and more respectful cleaning videos by Williams, who takes time to explain the process while ensuring the correct products are used. Meanwhile, many find McEwen’s videos problematic and criticise her for not adhering to proper graveyard decorum. McEwen makes a spectacle of sites of mourning, such as by pretending to vacuum graves, replacing flowers placed by others and making jokes. Viewers also speculate the products she uses may cause damage to the graves. Perceived intent plays a role in how each creator’s content is received. While Williams focuses on respectfully restoring graves to their former glory, McEwen positions herself as the focus and merely uses the graves for content. <h2>A complex emotional object</h2> Similar to other funerary objects such as coffins and urns, graves are associated with both the person who died and the fact of their death. As such, they are emotionally complex objects that bring both strength and sadness to those left behind. But graves are unique also in that they are private objects of grief exposed in a public context. Anyone visiting the graveyard can view and interact with them. Does that make them “fair game” for content creators? Graves don’t just represent deceased loved ones. They can also act as stand-ins in their absence, becoming stone bodies of sorts. As sociologist Margaret Gibson describes in her book <a href="https://www.mup.com.au/books/objects-of-the-dead-paperback-softback">Objects of the Dead: Mourning and Memory in Everyday Life</a>, “death reconstructs our experience of objects”. “There is the strangeness of realising that things have outlived persons, and, in this regard, the materiality of things is shown to be more permanent than the materiality of the body,” she says. Caring for and cleaning graves can therefore be interpreted as caring for the deceased, by extending their existence through the materiality of their resting place. Psychological researcher <a href="https://www.tandfonline.com/doi/abs/10.1080/1600910X.2018.1521339">Svend Brinkmann asserts</a> artefacts such as graves are “culturally sanctioned”, gaining “significance from a collective system of meaning”. In other words, we as a community create and uphold reverence for such items. This is partly why the desecration of graves is viewed as abhorrent. It is societally understood to be a desecration of the person themselves. It’s also why content creators must tread lightly. <h2>A reason for haunting?</h2> There are ways to interact with gravestones (and even create content) which acknowledge their complexity and connection to their owners. TikTok creator Rosie Grant (<a href="https://www.tiktok.com/@ghostlyarchive?lang=en">@ghostlyarchive</a>) bakes recipes found on headstones and records the process. She has even met with the families of the deceased <a href="https://www.independent.co.uk/life-style/food-and-drink/defining-dishes-ghostly-archive-tiktok-b2414122.html">to make the recipes together</a> and learn more about the people behind the engraving-worthy food. However, randomly cleaning the graves of strangers is fraught territory – and rife with potential privacy issues. It isn’t clear whether McEwen seeks permission from loved ones before cleaning graves, but contextually this seems unlikely. <a href="https://www.youtube.com/watch?v=nKkOS2GjCxk">Recent discussions</a> have also uncovered questionable editing in her videos. Some graves in her before-and-after videos have been edited to appear cleaner and to have their structure altered. McEwen’s pink foaming cleaner also appears to be a blue cleaner edited to appear pink, raising even more questions about intent and responsibility. While McEwen claims to be “honouring” lives by cleaning “final resting places”, the consensus from viewers is her actions are dishonourable. As one host <a href="https://www.youtube.com/watch?v=nKkOS2GjCxk">commented on a in podcast</a> discussing McEwen cleaning a baby’s grave while speaking in a kiddish voice: “F**k you, you’re going to get haunted.”<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/240553/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/edith-jennifer-hill-1018412">Edith Jennifer Hill</a>, Associate Lecturer, Learning & Teaching Innovation, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a> and <a href="https://theconversation.com/profiles/marina-deller-947925">Marina Deller</a>, Casual Academic, Creative Writing and English Literature, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Aussie family's refusal to sell family home could land them a $60m fortune

An Aussie family that repeatedly said no to selling their much-loved family home to developers could land them a $60million in Australia's booming property market, but the defiant family refuses to sell. A year ago, the Zammit family from Quakers Hill in Sydney's north west caught worldwide attention when they refused to sell their 20,000 sqm parcel of land to developers who had purchased all the other land around them. The family received offers of up to $50m to sell their home to complete the new development named The Ponds, but they refused to sell. That didn't deter developers who are still offering the owners a massive amount of cash to sell their homes, with offers reportedly around $60m now, meaning the family have earned another $10m or 20 per cent over the past year. According to PropTrack home prices in Quakers Hill have risen by 8.5 per cent over the past 12 months, meaning that the Zammits would have earned at least another $4.25 million. The median price of a home in Quakers hill is now at $1.172m, around a decade ago it was $700,000. Last year, one of the property owners, Diane Zammit, 50, told news.com.au that the neighbourhood used to be “farmland dotted with little red brick homes and cottages." “Every home was unique and there was so much space – but not any more. It’s just not the same,” she said. It is estimated that 50 houses could fit on the block of land if they chose to sell, but some of their neighbours reportedly don't want them to, as they like living in a cul-de-sac. Ray White Quakers Hill agent Taylor Bredin previously praised the family for staying put. “The fact that most people sold out years and years ago, these guys have held on. All credit to them," he told 7News. “Depending on how far you push the development plan, you’d be able to push anywhere from 40 to 50 properties on something like this, and when subdivided, a 300 square metre block would get a million dollars.” Images: Channel 7

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

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

I’m iron deficient. Which supplements will work best for me and how should I take them?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/alannah-mckay-1548258">Alannah McKay</a>, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a> Iron deficiency is common and can be debilitating. It mainly affects women. One in three premenopausal women <a href="https://static1.squarespace.com/static/57bfc0498419c24a01318ae2/t/607fc2e06ace2f22d5ca9a43/1618985699483/20210421+-+IDC+-+economic+impact+of+iron+deficiency+-+FINAL.pdf">are low in iron</a> compared to just 5% of Australian men. Iron deficiency particularly affects teenage girls, women who do a lot of exercise and those who are pregnant. The <a href="https://pubmed.ncbi.nlm.nih.gov/11160590/">body needs iron</a> to make new red blood cells, and to support energy production, the immune system and cognitive function. If you’re low, you may experience a range of symptoms including fatigue, weakness, shortness of breath, headache, irregular heartbeat and reduced concentration. If a blood test shows you’re iron deficient, your doctor may recommend you start taking an oral iron supplement. But should you take a tablet or a liquid? With food or not? And when is the best time of day? Here are some tips to help you work out how, when and what iron supplement to take. <h2>How do I pick the right iron supplement?</h2> The iron in your body is called “elemental iron”. Choosing the right oral supplement and dose will depend on how much elemental iron it has – your doctor will advise exactly how much you need. The sweet spot is between <a href="https://www.sciencedirect.com/science/article/pii/S0098299720300364?via%3Dihub">60-120 mg of elemental iron</a>. Any less and the supplement won’t be effective in topping up your iron levels. Any higher and you risk gastrointestinal symptoms such as diarrhoea, cramping and stomach pain. In Australia, iron salts are the most common oral supplements because they are cheap, effective and come in different delivery methods (tablets, capsules, liquid formulas). <a href="https://www.ncbi.nlm.nih.gov/books/NBK557376/">The iron salts</a> you are most likely to find in your local chemist are ferrous sulfate (~20% elemental iron), ferrous gluconate (~12%) and ferrous fumarate (~33%). These formulations <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3867244/">all work similarly</a>, so your choice should come down to dose and cost. Many multivitamins may look like an iron supplement, but it’s important to note they usually have too little iron – usually less than 20 mg – to correct an iron deficiency. <h2>Should I take tablets or liquid formulas?</h2> Iron contained within a tablet is <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3867244/">just as well absorbed</a> as iron found in a liquid supplement. Choosing the right one usually comes down to personal preference. The main difference is that liquid formulas tend to contain less iron than tablets. That means you might need to take more of the product to get the right dose, so using a liquid supplement could work out to be more expensive in the long term. <h2>What should I eat with my iron supplement?</h2> Research <a href="https://onlinelibrary.wiley.com/doi/epdf/10.1002/ajh.26987">has shown</a> you will absorb more of the iron in your supplement if you take it on an empty stomach. But this can cause more gastrointestinal issues, so might not be practical for everyone. If you do take your supplement with meals, it’s important to think about what types of food will boost – rather than limit – iron absorption. For example, taking the supplement alongside vitamin C improves your body’s ability to absorb it. Some supplements already contain vitamin C. Otherwise you could take the supplement along with a glass of orange juice, or other <a href="https://ods.od.nih.gov/factsheets/VitaminC-HealthProfessional/">vitamin C-rich foods</a>. On the other hand, tea, coffee and calcium all <a href="https://onlinelibrary.wiley.com/doi/epdf/10.1002/ajh.26987">decrease the body’s ability to absorb iron</a>. So you should try to limit these close to the time you take your supplement. <h2>Should I take my supplement in the morning or evening?</h2> The best time of day to take your supplement is in the morning. The body can <a href="https://journals.lww.com/acsm-msse/fulltext/2019/10000/the_impact_of_morning_versus_afternoon_exercise_on.20.aspx">absorb significantly more</a> iron earlier in the day, when concentrations of hepcidin (the main hormone that regulates iron) are at their lowest. Exercise also affects the hormone that regulates iron. That means taking your iron supplement after exercising can <a href="https://journals.humankinetics.com/view/journals/ijsnem/32/5/article-p359.xml">limit your ability to absorb it</a>. Taking your supplement in the hours following exercise will mean significantly poorer absorption, especially if you take it between two and five hours after you stop. <a href="https://journals.lww.com/acsm-msse/fulltext/2024/01000/iron_absorption_in_highly_trained_male_runners_.14.aspx">Our research</a> has shown if you exercise every day, the best time to take your supplement is in the morning before training, or immediately after (within 30 minutes). <h2>My supplements are upsetting my stomach. What should I do?</h2> If you experience gastrointestinal side effects such as diarrhoea or cramps when you take iron supplements, you may want to consider taking your supplement every second day, rather than daily. Taking a supplement every day is still the fastest way to restore your iron levels. But a recent study <a href="https://www.thelancet.com/journals/eclinm/article/PIIS2589-5370(23)00463-7/fulltext#%20">has shown</a> taking the same total dose can be just as effective when it’s taken on alternate days. For example, taking a supplement every day for three months works as well as every second day for six months. This results in fewer side effects. Oral iron supplements can be a cheap and easy way to correct an iron deficiency. But ensuring you are taking the right product, under the right conditions, is crucial for their success. It’s also important to check your iron levels prior to commencing iron supplementation and do so only under medical advice. In large amounts, <a href="https://www.ncbi.nlm.nih.gov/books/NBK430862/">iron can be toxic</a>, so you don’t want to be consuming additional iron if your body doesn’t need it. If you think you may be low on iron, talk to your GP to find out your best options.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/235315/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/alannah-mckay-1548258">Alannah McKay</a>, Postdoctoral Research Fellow, Sports Nutrition, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

What’s the difference between ‘strep throat’ and a sore throat? We’re developing a vaccine for one of them

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/kim-davis-1535254">Kim Davis</a>, <a href="https://theconversation.com/institutions/murdoch-childrens-research-institute-1027">Murdoch Children's Research Institute</a>; <a href="https://theconversation.com/profiles/alma-fulurija-1535255">Alma Fulurija</a>, <a href="https://theconversation.com/institutions/telethon-kids-institute-1608">Telethon Kids Institute</a>, and <a href="https://theconversation.com/profiles/myra-hardy-1535253">Myra Hardy</a>, <a href="https://theconversation.com/institutions/murdoch-childrens-research-institute-1027">Murdoch Children's Research Institute</a> the time of the year for coughs, colds and sore throats. So you might have heard people talk about having a “strep throat”. But what is that? Is it just a bad sore throat that goes away by itself in a day or two? Should you be worried? Here’s what we know about the similarities and differences between strep throat and a sore throat, and why they matter. <h2>How are they similar?</h2> It’s difficult to tell the difference between a sore throat and strep throat as they look and feel similar. People usually have a fever, a bright red throat and sometimes painful lumps in the neck (swollen lymph nodes). A throat swab can help diagnose strep throat, but the results can take a few days. Thankfully, both types of sore throat usually get better <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8655103/">by themselves</a>. <h2>How are they different?</h2> Most sore throats are caused by viruses such as common cold viruses, the flu (influenza virus), or the virus that causes glandular fever (Epstein-Barr virus). These viral sore throats can occur at any age. Antibiotics don’t work against viruses so if you have a viral sore throat, you won’t get better faster if you take antibiotics. You might even have some unwanted <a href="https://www.ncbi.nlm.nih.gov/books/NBK401243/#:%7E:text=People%20may%20then%20wonder%20whether,infection%2C%20such%20as%20bacterial%20tonsillitis.">antibiotic side-effects</a>. But strep throat is caused by Streptococcus pyogenes bacteria, also known as strep A. Strep throat is most common in <a href="https://www.tandfonline.com/doi/full/10.2217/fmb-2021-0077">school-aged children</a>, but can affect other age groups. In some cases, you may need antibiotics to avoid some rare but serious complications. In fact, the potential for complications is one key difference between a viral sore throat and strep throat. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/605956/original/file-20240710-19-irooun.png?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/605956/original/file-20240710-19-irooun.png?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/605956/original/file-20240710-19-irooun.png?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=405&fit=crop&dpr=1 600w, https://images.theconversation.com/files/605956/original/file-20240710-19-irooun.png?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=405&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/605956/original/file-20240710-19-irooun.png?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=405&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/605956/original/file-20240710-19-irooun.png?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=508&fit=crop&dpr=1 754w, https://images.theconversation.com/files/605956/original/file-20240710-19-irooun.png?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=508&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/605956/original/file-20240710-19-irooun.png?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=508&fit=crop&dpr=3 2262w" alt="" /></a><figcaption></figcaption></figure> Generally, a viral sore throat is <a href="https://www.bmj.com/content/347/bmj.f6867">very unlikely</a> to cause complications (one exception is those caused by Epstein-Barr virus which has been associated with illnesses such as <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3893202/">chronic fatigue syndrome</a>, <a href="https://www.science.org/doi/10.1126/science.abj8222">multiple sclerosis</a> and certain <a href="https://www.thelancet.com/journals/eclinm/article/PIIS2589-5370(22)00404-7/fulltext">cancers</a>). But strep A can cause invasive disease, a rare but serious complication. This is when bacteria living somewhere on the body (usually the skin or throat) get into another part of the body where there shouldn’t be bacteria, such as the bloodstream. This can make people extremely sick. Invasive strep A infections and deaths have been <a href="https://www.who.int/emergencies/disease-outbreak-news/item/2022-DON429">rising in recent years</a> <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10786649/">around the world</a>, especially in young children and older adults. This may be due to a number of factors such as increased social mixing at this stage of the COVID pandemic and an increase in circulating common cold viruses. But overall the reasons behind the increase in invasive strep A infections are not clear. Another rare but serious side effect of strep A is autoimmune disease. This is when the body’s immune system makes antibodies that react against its own cells. The most common example is <a href="https://www.who.int/news-room/fact-sheets/detail/rheumatic-heart-disease">rheumatic heart disease</a>. This is when the body’s immune system damages the heart valves a few weeks or months after a strep throat or skin infection. <a href="https://www.nejm.org/doi/10.1056/NEJMoa2102074?url_ver=Z39.88-2003&rfr_id=ori:rid:crossref.org&rfr_dat=cr_pub%20%200pubmed">Around the world</a> more than 40 million people live with rheumatic heart disease and more than 300,000 die from its complications every year, mostly in developing countries.

Young Aussies hit back at Steve Price for calling them "lazy"

Young Aussies have hit back at Steve Price after being criticised as lazy by the broadcaster. Prince unleashed at younger generations on The Project while they were discussing the campaign for more leave initiated by the Shop, Distributive and Allied Employees Association, which is pushing to increase annual leave to five weeks a year. The union hopes to ease burnout in employees, and Price was not impressed with the calls for extra leave. "We're trying to get productivity up in this country," he said. "So we've got people refusing to go back to the office, working from home in barely washed tracksuit tops and bottoms, three days a week. "And now they want five weeks holiday." Georgie Tunny, a millennial, hit back at the boomer by arguing that the "work culture" has changed, especially among those new to the workforce. "Especially for the younger generations, they see work completely differently," she said. Price interrupted her saying that young Aussies just did not want to "work very hard", to which Tunny replied: "There's been a death of your job as your identity or career." Social media users were quick to back Tunny, and took aim at Price. "Where's the incentive for young people to work hard when working hard won't buy you a house or even afford you basic veggies," one said. "You get what you pay for, and it's not worth it to work hard. There's literally no benefit to working as hard as you can," another added. "When you're priced out of the market, priced out of holidays and priced out of necessities, what motivation is there to care or be productive," another added. Others suggested that employers should "increase wages and introduce bonuses as incentives," to encourage their staff to work harder. "Nobody is interested in working themselves to death for scraps," one person said. "I don't want to work very hard for CEOs to make millions while I'm barley able to afford bread," another said. "Our generation is just sick of working hard to have all the higher ups take the credit and the bag. We know what we're worth," a third added. A recent Productivity Commission report found that Aussies born after 1990 are finding more difficult than previous generations to move up the financial ladder. The report also found that young Aussies are increasingly earning less than their parents did at the same age, with the global financial crisis partially to blame for the weak income growth.

Taking too many medications can pose health risks. Here’s how to avoid them

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/caroline-sirois-1524891">Caroline Sirois</a>, <a href="https://theconversation.com/institutions/universite-laval-1407">Université Laval</a> When we see an older family member handling a bulky box of medications sorted by day of the week, we might stop and wonder, is it too much? How do all those pills interact? The fact is, as we get older we are more likely to develop different chronic illnesses that require us to take several different medications. This is known as polypharmacy. The concept applies to people taking five or more medications, but there are all sorts of <a href="https://doi.org/10.3390/pharmacy7030126">definitions with different thresholds</a> (for example, four, 10 or 15 medicines). I’m a pharmacist and pharmacoepidemiologist interested in polypharmacy and its impact on the population. The research I carry out with my team at the Faculty of Pharmacy at Université Laval focuses on the appropriate use of medication by older family members. We have published this <a href="https://doi.org/10.1093/ageing/afac244">study</a> on the perceptions of older adults, family carers and clinicians on the use of medication among persons over 65. <h2>Polypharmacy among older adults</h2> Polypharmacy is very common among older adults. In 2021, a quarter of persons over 65 in Canada were prescribed <a href="https://www.cihi.ca/en/drug-use-among-seniors-in-canada">more than ten different classes of medication</a>. In Québec, persons over 65 used an average of <a href="https://www.inspq.qc.ca/sites/default/files/publications/2679_portrait_polypharmacie_aines_quebecois.pdf">8.7 different drugs in 2016</a>, the latest year available for statistics. Is it a good idea to take so many drugs? According to <a href="https://journals.sagepub.com/doi/10.1177/07334648211069553">our study</a>, the vast majority of seniors and family caregivers would be willing to stop taking one or more medications if the doctor said it was possible, even though most are satisfied with their treatments, <a href="https://doi.org/10.1093/ageing/afac244">have confidence in their doctors</a> and feel that their doctors are taking care of them to the best of their ability. In the majority of cases, medicine prescribers are helping the person they are treating. Medications have a positive impact on health and are essential in many cases. But while the treatment of individual illnesses is often adequate, the whole package can sometimes become problematic. <h2>The risks of polypharmacy: 5 points to consider</h2> When we evaluate cases of polypharmacy, we find that the quality of treatment is often compromised when many medications are being taken. <ol> <li> Drug interactions: polypharmacy increases the risk of drugs interacting, which can lead to undesirable effects or reduce the effectiveness of treatments. </li> <li> A drug that has a positive effect on one illness may have a negative effect on another: what should you do if someone has both illnesses? </li> <li> The greater the number of drugs taken, the greater the risk of undesirable effects: for adults over 65, for example, there is an increased risk of confusion or falls, which have significant consequences. </li> <li> The more medications a person takes, the more likely they are to take a <a href="https://www.doi.org/10.1093/fampra/cmz060">potentially inappropriate medication</a>. For seniors, these drugs generally carry more risks than benefits. For example, benzodiazepines, medicine for anxiety or sleep, are the <a href="https://www.inspq.qc.ca/sites/default/files/publications/2575_utilisation_medicaments_potentiellement_inappropries_aines.pdf">most frequently used class</a> of medications. We want to reduce their use as much as possible <a href="https://www.canada.ca/en/health-canada/services/substance-use/controlled-illegal-drugs/benzodiazepines.html">to avoid negative impacts</a> such as confusion and increased risk of falls and car accidents, not to mention the risk of dependence and death. </li> <li> Finally, polypharmacy is associated with various adverse health effects, such as an <a href="https://www.doi.org/10.1007/s41999-021-00479-3">increase in frailty, hospital admissions and emergency room visits</a>. However, studies conducted to date have not always succeeded in isolating the effects specific to polypharmacy. As polypharmacy is more common among people with multiple illnesses, these illnesses may also contribute to the observed risks. </li> </ol> Polypharmacy is also a combination of medicines. There are almost as many as there are people. The risks of these different combinations can vary. For example, the risks associated with a combination of five potentially inappropriate drugs would certainly be different from those associated with blood pressure medication and vitamin supplements. Polypharmacy is therefore complex. <a href="https://doi.org/10.1186/s12911-021-01583-x">Our studies attempt to use artificial intelligence</a> to manage this complexity and identify combinations associated with negative impacts. There is still a lot to learn about polypharmacy and its impact on health. <h2>3 tips to avoid the risks associated with polypharmacy</h2> What can we do as a patient, or as a caregiver? <ol> <li> Ask questions: when you or someone close to you is prescribed a new treatment, be curious. What are the benefits of the medication? What are the possible side effects? Does this fit in with my treatment goals and values? How long should this treatment last? Are there any circumstances in which discontinuing it should be considered ? </li> <li> Keep your medicines up to date: make sure they are all still useful. Are there still any benefits to taking them? Are there any side effects? Are there any drug interactions? Would another treatment be better? Should the dose be reduced? </li> <li> Think about de-prescribing: this is an increasingly common clinical practice that involves stopping or reducing the dose of an inappropriate drug after consulting a health-care professional. It is a shared decision-making process that involves the patient, their family and health-care professionals. The <a href="https://www.deprescribingnetwork.ca">Canadian Medication Appropriateness and Deprescribing Network</a> is a world leader in this practice. It has compiled a number of tools for patients and clinicians. You can find them on their website and subscribe to the newsletter. </li> </ol> <h2>Benefits should outweigh the risks</h2> Medications are very useful for staying healthy. It’s not uncommon for us to have to take more medications as we age, but this shouldn’t be seen as a foregone conclusion. Every medication we take must have direct or future benefits that outweigh the risks associated with them. As with many other issues, when it comes to polypharmacy, the saying, “everything in moderation,” frequently applies.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/230612/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/caroline-sirois-1524891">Caroline Sirois</a>, Professor in Pharmacy, <a href="https://theconversation.com/institutions/universite-laval-1407">Université Laval</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Why you should expect to pay more tourist taxes – even though the evidence for them is unclear

In the UK, a council in the county of Kent <a href="https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Ftheconversationuk.cmail20.com%2Ft%2Fr-l-tiuhhult-iukktlluuk-o%2F&data=05%7C02%7Cr.a.gwilym%40bangor.ac.uk%7C39ac5db833674c1a026508dc63a24fa7%7Cc6474c55a9234d2a9bd4ece37148dbb2%7C0%7C0%7C638494795990617858%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C0%7C%7C%7C&sdata=D6oVizx3pFoiwRaTcKaakQ079%2FIQx86jcbFpj2%2FS0RQ%3D&reserved=0">has recommended</a> introducing a tourism tax on overnight stays in the county. In Scotland, it seems likely that <a href="https://edinburgh.org/planning/local-information/visitor-levy-for-edinburgh/#:%7E:text=The%20Edinburgh%20Visitor%20Levy%2C%20otherwise%20referred%20to%20as,would%20then%20be%20invested%20back%20into%20the%20city.">visitors to Edinburgh</a> will be paying a fee by 2026, and the Welsh government <a href="https://www.walesonline.co.uk/news/wales-news/welsh-government-announces-tourists-pay-26591498">plans to introduce</a> similar legislation later this year. Such taxes may seem new to the UK, but there are more than 60 destinations around the world where this type of tax is already in place. These vary from a nationwide tax in Iceland to various towns across the US. Some have been in place for a long time (France was the <a href="https://www.impots.gouv.fr/taxe-de-sejour">first in 1910</a>), but most were introduced during the last decade or two. Before the pandemic really struck (and tourism was put on hold), 2020 was described by one newspaper as the <a href="https://www.telegraph.co.uk/travel/news/tourist-tax-amsterdam-venice/">“year of the tourist tax”</a>, as Amsterdam joined an ever-growing list of destinations, which includes Paris, Malta and Cancun, to charge visitors for simply visiting. Introducing these tourist taxes has often been controversial, with industry bodies <a href="https://www.bbc.co.uk/news/uk-wales-62707152">voicing concerns</a> about the potential impacts on the tourist trade. And it appears that the link between such levies and visitor numbers is not simple, with several studies reaching different conclusions. For example, some have suggested that tourism levies have hindered <a href="https://www-sciencedirect-com.bangor.idm.oclc.org/science/article/pii/S0261517704000238">international tourism in the Balearics</a> and <a href="https://journals-sagepub-com.bangor.idm.oclc.org/doi/pdf/10.1177/00472875211053658">the Maldives</a>, and that they may dissuade people from participating in <a href="https://eprints.bournemouth.ac.uk/35087/1/ADEDOYIN%2C%20Festus%20Fatai_Ph.D._2020.pdf">domestic tourism</a>. Yet in one of the world’s most popular tourism spots with a levy, Barcelona, visitor numbers have <a href="https://groupnao.com/wp-content/uploads/2020/11/TOURISM-TAXES-BY-DESIGN-NOV12-2020_rettet-compressed-2.pdf">consistently risen</a>, with hotel guests increasing from 7.1 million in 2013 to 9.5 million in 2019. In fact, the relationship between a visitor levy and tourist flow is so complex that there is no unified view, even within the same country. Italy has been one of the most studied, and results <a href="https://crenos.unica.it/crenosterritorio/sites/default/files/allegati-pubblicazioni-tes/Indagine_Villasimius_Quaderno_Crenos_ISBN.pdf">are inconsistent</a> <a href="https://onlinelibrary.wiley.com/doi/abs/10.1002/jtr.2123">there too</a>. Another study, looking at three neighbouring Italian seaside spots finds that only in one destination has the visitor levy <a href="https://www.rivisteweb.it/doi/10.1429/77318">reduced tourist flow</a>. And a study on the Italian cities of Rome, Florence and Padua shows that these cities <a href="https://link-springer-com.bangor.idm.oclc.org/chapter/10.1007/978-3-030-61274-0_23">have not experienced any negative effects</a> either in terms of domestic or international demand. So the impact of tourism taxes on visitor numbers is inconclusive. But what about other effects, such as the potential benefits of spending the revenues raised? As part of an ongoing research project, we looked at seven different destinations in which tourist taxes are levied to look at how the money raised is then spent. For most places, tourism tax revenues were being used to fund marketing and branding – so invested directly into promoting more tourism. The income was also commonly used to fund tourism infrastructure, from public toilets and walking or cycling paths to a multi-billion dollar <a href="https://www.occc.net/About-Us-Media-Relations-Press-Releases/ArticleID/569/Orange%20County%20Board%20Votes%20to%20Approve%20Convention%20Center%20Completion%20with%20Tourist%20Development%20Tax%20Revenues">convention centre</a> in Orange County, Florida. In <a href="https://www.caib.es/sites/impostturisme/en/l/projects/?mcont=95762">the Balearics</a>, revenues tend to go to projects that mitigate the negative impacts of tourism on the environment, culture and society of the islands. These include waste management, conserving natural habitats and historical monuments, and social housing. But in general, tourism taxes have been implemented successfully across the destinations we looked at, and there is little evidence of tourists being put off from visiting. Research also suggests that when tourists are told what the levy is used for – and when it relates directly to <a href="https://www.mdpi.com/2227-7099/5/2/21">improving their experience</a> or <a href="https://ejtr.vumk.eu/index.php/about/article/view/2813/605">enhancing sustainable tourism</a> – <a href="https://www-sciencedirect-com.bangor.idm.oclc.org/science/article/pii/S2212571X20301621?casa_token=HcD-yQh65XcAAAAA:GhVRo4vX9JY1E3Lcx5ZPaTr5ZHArMGNrmK_2ASJCtMPjVpdCQLdun25BmFEYquGgz8-1riOWdg">tourists are willing to accept and pay</a> the levy. <h2>Day trippers</h2> For many tourism destinations, the major problem is not overnight tourists, but rather <a href="https://www.mirror.co.uk/news/uk-news/fuming-snowdonia-visitors-demand-self-30203642">day visitors</a> who use local resources while making little in the way of a financial contribution. For these reasons, taxes might also be used to deter day visits and instead encourage longer stays. <a href="https://www.economist.com/why-venice-is-starting-to-charge-tourists-to-enter?utm_medium=cpc.adword.pd&utm_source=google&ppccampaignID=18156330227&ppcadID=&utm_campaign=a.22brand_pmax&utm_content=conversion.direct-response.anonymous&gad_source=1&gclid=Cj0KCQjw_qexBhCoARIsAFgBleshST3IQMYR8hONLSLnA_loj9dukAqxURhdVCn1RmGeD5iOQzw_r2caAsqrEALw_wcB&gclsrc=aw.ds">Venice is at the forefront</a> of this shift. And in April 2024, after long discussions between the local authority, residents and business owners, Venice started a <a href="https://cdamedia.veneziaunica.it/en/video/it-is-difficult-to-book-a-visit-to-venice/">trial</a> of a day visitor tax (a so-called <a href="https://cda.veneziaunica.it/en">“access fee”</a>). Back in Kent, it may take longer for any such radical plans to come to fruition. In contrast to Scotland and Wales, there are currently no national plans to <a href="http://www.parliament.uk/written-questions-answers-statements/written-question/commons/2023-09-13/199425">introduce tourist taxes</a> in England. This might be considered shortsighted, given the dire need of many destinations in England to improve local infrastructure that tourists rely on, including <a href="https://www.reading.ac.uk/news/2024/Research-News/Swimming-in-sewage-Bathing-forecasts-not-keeping-people-safe">clean bathing water</a> and <a href="https://www.lancs.live/news/cumbria-news/lake-district-warning-parking-issues-27173650">public transport</a>. In <a href="https://www.accountingweb.co.uk/business/finance-strategy/manchester-acts-as-trailblazer-for-tourist-tax">Manchester</a> and <a href="https://www.ft.com/content/0e0385e6-29ec-4302-9903-6fbf63d8854a">Liverpool</a>, businesses have implemented voluntary overnight charges on visitors, in the absence of the statutory basis to implement compulsory levies. Many other English towns and cities will probably follow their lead. Tourism taxes are something we might all have to consider budgeting for in our future travel plans, wherever we choose to visit.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/229134/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/rhys-ap-gwilym-1531623">Rhys ap Gwilym</a>, Senior Lecturer in Economics, <a href="https://theconversation.com/institutions/bangor-university-1221">Bangor University</a> and <a href="https://theconversation.com/profiles/linda-osti-1431286">Linda Osti</a>, Senior Lecturer in Tourism Management, <a href="https://theconversation.com/institutions/bangor-university-1221">Bangor University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Travel Trouble

Why your health issues keep flaring up – and how to switch them off

Author, accredited Clinical Nutritionist, Functional Medicine Practitioner, Coach, Trauma Therapist & PhD Scholar Filipa Bellette shows us how you can tap into your body's ancient wisdom and finally find relief from chronic health issues by learning to deeply listen, connect, and trust yourself. Have you been struggling with chronic health issues for years, maybe even decades? Things like fatigue, anxiety, gut issues, food sensitivities, body pain, headaches, menopausal symptoms (if you’re a woman)? You’ve probably tried everything under the sun - GP visits, lab tests, naturopaths, supplements, diets, even yoga and breath-work - but still those annoying symptoms keep coming back. Sound familiar? My Chronic Health Story I was there once too. I have experienced chronic “weird” health issues three times. I struggled with a mix of anxiety, insomnia, gut issues, low immunity, body pain, female hormone issues, low energy, chemical sensitivity and histamine intolerance. The first time was after my first baby and I resolved some of the issues with lifestyle changes - sleep, movement, wholefoods and low-tox living. It was GREAT, until baby number two came along, and all my symptoms flared back up, even though my lifestyle was dialled in. This is when I came across functional medicine, and I <a href="https://www.chrisandfilly.fm/" target="_blank" rel="noopener">became a practitioner</a> and started lab testing my own body systems and therapeutically supporting imbalances in my body with natural medicine supplements. This worked amazing, and I got on top of my symptoms. Until … COVID came along, and I was under a lot of stress, and all the same issues flared up again! I realised I still hadn’t addressed the deepest root-cause of my health issues, and that was the “baggage” stuck in my unconscious mind (dysfunctional unconscious core beliefs, deep-seated perfectionism, people pleasing and addictive-doing patterns, and unprocessed past distressing events), that were dysregulating my nervous system. The Missing Piece In Healthcare What I’ve found in the health industry as a whole, is that we have lost the ability to communicate with our bodies. You go to a GP or medical specialist and they are the expert dictating what tests to do, and what medications you need to be on. I even see this in natural medicine modalities, like <a href="https://www.chrisandfilly.fm/" target="_blank" rel="noopener">functional medicine (which I practice)</a>, where the practitioner runs some labs and creates a protocol for the patient. This is great for therapeutic support, and something I do with clients, however, it is still promoting the message that “others know best.” This is simply not true. You Are The Expert of Your Body I wholeheartedly believe that 95% of what you need to heal is already inside of you. Our bodies hold ancient wisdom, and you know inherently what is good for you, and what isn’t. The thing is, society as a whole has lost the ability to listen to and communicate with our bodies. I’m here to change that! In our practice we work with clients to rebuild trust with self, to learn how THEIR body communicates to THEM, and to act on the messages. When you act, magic happens! I have literally seen symptoms “switch off” in the moment when clients listen to their bodies and act accordingly. For example, I spoke at a business women’s conference on the Gold Coast on the weekend, and took attendees through a process to communicate with their unconscious mind through the symptoms in their bodies. One lady stood up at the end and said her chronic headache that had been hanging around for days completely disappeared (she’d even taken 4 pain-killers that morning, which didn’t budge the headache!). Oh my gosh, how cool! I see this again and again for myself and with our clients, how quickly chronic health issues can be resolved when you deeply listen, connect, trust and love yourself. I’ve seen: <ul> <li>Chronic fatigue disappear over months</li> <li>Heartburn clear up in a moment</li> <li>Anxiety ease</li> <li>Chronic pain in the body switch off within days</li> <li>Brain fog lift</li> <li>Food sensitivities dissolve</li> <li>Plus so much more!</li> </ul> It’s Not Woo-Woo – It’s Science If you’re someone who needs the facts, let me tell you this way of holistic healing isn’t just “woo woo” or “magic”. It’s how we’re wired as human beings. For example, let’s look at pain. Pain is not your enemy. As humans we have evolved for safety and survival. Pain is a primitive way our bodies have warned us of danger. You touch fire, you get burned, your brain creates a neural pathway to never touch the fire again because it hurts! The nervous system, too, is so important at sending you messages of safety or danger. It’s always trying to keep us safe and alive. So if it deems something unsafe - this could be your own beliefs about yourself, self-doubt, uncertainty, shame, guilt, frustration, or fears about eating certain foods, smelling perfumes, being around mould, etc – your system gets very good at creating symptoms to alert you of danger, which then leads to chronic health issues. When you can create the space to ask: what is unsafe? What’s the story behind the symptom? And what do you need from me, body, to feel safe and loved and to heal? Then you can finally end your state of dysregulation and body burnout. Filipa Bellette, author of Ending Body Burnout ($29.95), is an accredited Clinical Nutritionist, Functional Medicine Practitioner, Coach, Trauma Therapist & PhD Scholar. She is co-founder of multi award-winning health practice Chris & Filly Functional Medicine, best known for ending body burnout (for good!) in “busy” people with energy, mood & gut issues.

COVID vaccines saved millions of lives – linking them to excess deaths is a mistake

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/paul-hunter-991309">Paul Hunter</a>, <a href="https://theconversation.com/institutions/university-of-east-anglia-1268">University of East Anglia</a> A recent <a href="https://bmjpublichealth.bmj.com/content/2/1/e000282">study</a> has sparked another <a href="https://nypost.com/2024/06/06/us-news/covid-vaccines-may-have-helped-fuel-rise-in-excess-deaths-since-pandemic-study/">round of</a> <a href="https://www.telegraph.co.uk/news/2024/06/04/covid-vaccines-may-have-helped-fuel-rise-in-excess-deaths/">headlines</a> <a href="https://www.gbnews.com/health/covid-vaccine-side-effects-deaths">claiming</a> that COVID vaccines caused excess deaths. This was accompanied by a predictable outpouring of <a href="https://x.com/DrAseemMalhotra/status/1797922073798717524">I-told-you-sos</a> on social media. Excess deaths are a measure of how many more deaths are being recorded in a country over what would have been expected based on historical trends. In the UK, and in many other countries, death rates have been higher during the years 2020 to 2023 than would have been expected based on historic trends from before the pandemic. But that has been known for some time. A couple of years ago I wrote an article for <a href="https://theconversation.com/summer-2022-saw-thousands-of-excess-deaths-in-england-and-wales-heres-why-that-might-be-189351">The Conversation</a> pointing this out and suggesting some reasons. But has anything changed? The authors of the new study, published in BMJ Public Health, used publicly available data from <a href="https://ourworldindata.org/COVID-vaccinations">Our World in Data</a> to determine which countries had “statistically significant” excess deaths – in other words, excess deaths that couldn’t be explained by mere random variation. They studied the years 2020 to 2022 and found that many, but not all, countries did indeed report excess deaths. The authors did not try to explain why these excess deaths occurred, but the suggestion that COVID vaccines could have played a role is clear from their text – and indeed widely interpreted as such by certain newspapers. There is no doubt that a few deaths were associated with <a href="https://journals.sagepub.com/doi/full/10.1177/25166026211053485">the COVID vaccines</a>, but could the vaccination programme explain the large number of excess deaths – 3 million in 47 countries – that have been reported? Based on <a href="https://www.ons.gov.uk/peoplepopulationandcommunity/birthsdeathsandmarriages/deaths/articles/excessdeathsinenglandandwales/march2020todecember2021">death certificates</a>, during 2020 and 2021 there were more deaths from COVID than estimated excess deaths in the UK. So during the year 2021 when most vaccine doses were administered, there were actually fewer non-COVID deaths than would have been expected. It was only in 2022 that excess deaths <a href="https://www.ons.gov.uk/peoplepopulationandcommunity/birthsdeathsandmarriages/deaths/articles/deathregistrationsummarystatisticsenglandandwales/2022">exceeded COVID deaths</a>. If the vaccination campaign was contributing to the excess deaths that we have seen in recent years, then we should expect to see more deaths in people who have been vaccinated than in those who have not. The most reliable analysis in this regard was done by the UK’s <a href="https://www.ons.gov.uk/peoplepopulationandcommunity/birthsdeathsandmarriages/deaths/articles/excessdeathsinenglandandwales/march2020todecember2021">Office for National Statistics (ONS)</a>. In this analysis, the ONS matched death registrations with the vaccine histories of each death recorded. They then calculated “age-standardised death rates” to account for age differences between those vaccinated and those not. What the ONS found was that in all months from April 2021 to May 2023, the death rate <a href="https://www.ons.gov.uk/redir/eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpbmRleCI6MSwicGFnZVNpemUiOjEwLCJwYWdlIjoxLCJ1cmkiOiIvcGVvcGxlcG9wdWxhdGlvbmFuZGNvbW11bml0eS9iaXJ0aHNkZWF0aHNhbmRtYXJyaWFnZXMvZGVhdGhzL2RhdGFzZXRzL2V4Y2Vzc2RlYXRoc2luZW5nbGFuZGFuZHdhbGVzIiwibGlzdFR5cGUiOiJyZWxhdGVkZGF0YSJ9.Cot-XDe8Rr07paGllBNnVVz1nTqnXfVafn2woA3tk0c">from all causes was higher</a> in the unvaccinated than in people who had been vaccinated at least once. That deaths from all causes were lower in the vaccinated than the unvaccinated should come as no surprise given that COVID was a major cause of death in 2021 and 2022. And there is ample evidence of the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10492612/">protective effect of vaccines</a> against severe COVID and death. But what is even more convincing is that, even when known COVID deaths were excluded in the ONS report, the death rate in the unvaccinated was still higher, albeit not by very much in more recent months. Some COVID deaths would certainly not have been recognised as such. But, on the other hand, people with chronic conditions, such as diabetes, were a high priority for vaccination. And these people would have been at increased risk of death even before the pandemic. <h2>Possible causes</h2> If the vaccine is not the cause of the excess deaths, what was? The major cause of the excess deaths reported in the first two years of the BMJ Public Health study was deaths from COVID. But by 2022, excess deaths exceeded COVID deaths in many countries. Possible <a href="https://theconversation.com/summer-2022-saw-thousands-of-excess-deaths-in-england-and-wales-heres-why-that-might-be-189351">explanations</a> for these excess deaths include longer-term effects of earlier COVID infections, the return of infections such as influenza that had been suppressed during the COVID control measures, adverse effects of lockdowns on physical and mental health, and delays in the diagnosis of life-threatening infections as health services struggled to cope with the pandemic and its aftermath. We do need to look very carefully at how the pandemic was managed. There is still considerable debate about the effectiveness of different behavioural control measures, such as self-isolation and lockdowns. Even when such interventions were effective at reducing transmission of COVID, what were the harms and were the gains worth the harms? Nevertheless, we can be confident that the excess deaths seen in recent years were not a consequence of the vaccination campaign.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/231776/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/paul-hunter-991309">Paul Hunter</a>, Professor of Medicine, <a href="https://theconversation.com/institutions/university-of-east-anglia-1268">University of East Anglia</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

"I killed them": Major twist in slain Aussie brothers case

The girlfriend of the man who allegedly killed Perth brothers Callum and Jake Robinson has reportedly "flipped" on her partner, becoming the star witness in the case. Ari Gisel García Cota was arrested earlier this week, along with her partner Jesús Gerardo Garcia Cota and his brother Cristian Alejandro Garcia, after the bodies of the Robinson brothers and their friend were found on Saturday in a desolate section of Santo Tomas in the Baja California region. According to Mexico police, the three men were killed as a result of a failed robbery, after locals attempted to steal the tyres from their pick-up truck. The bodies of the three men were recovered from a 15-metre deep well, with each man having fatal gun shot wounds to the head. In a major twist to the case, prosecutors revealed to court on Wednesday that Ari Gisel García Cota had become a key witness in the case after turning on the "ringleader" of the crime. “She has flipped on the ringleader and the evidence she’s provided to the prosecution will lead this case going forward,” Nine News correspondent Alison Piotrowski, who was in the courtroom, told 2GB’s Ben Fordham on Thursday. “What’s alleged is that Jesús Gerardo was driving her car that night when he went out to that remote campsite. The prosecution is saying what we’ve been talking about for the last couple of days has potentially happened, that the two Aussies and their American friend were ambushed.” Prosecutors allege Jesús Gerardo “killed them, took their tyres, put the tyres on her car and drove back”. When he went back to their house, the court heard he allegedly told Ari Gisel, “I f**ked up three gringos (English-speaking foreigner).” “She said to him, ‘What do you mean by that?’ And he told her, ‘I killed them’, and then showed her the vehicle with Jake, Callum and Jack’s tyres on her car,” Piotrowski said. “Ari was arrested later that day, she had fled to her mother’s house to get away from him. When the officers arrested her they said, ‘You have the right to remain silent’, and she said, ‘I don’t want to be silent, I want to tell you what I know. I’m a victim of domestic violence, I want to protect my four-year-old so let me help you with this case.’ So she has spectacularly turned on him and will now be crucial in this case moving forward.” Piotrowski added that the stunning revelation explained why Mexican officials “have been able to put him behind bars so quickly and also how they found the bodies”. “This conversation that he had with his girlfriend is pretty damning,” she said. So far only Jesús Gerardo Garcia Cota has been charged in connection with the deaths of the three men, and only with forced kidnapping, while Ari Gisel García Cota and Cristian Alejandro Garcia have only been charged with drug possession. Piotrowski said the kidnapping charges may not be upgraded to murder until the next court hearing, although the judge has more questions about how the three men were killed. “The judge did say that he can’t understand how one sole person could have done this, essentially kidnap and kill three men and take their tyres, it seems like too much,” she said. “He suggested that the prosecution needed to look into more suspects, that they needed to broaden their investigation because it couldn’t have been done by one man alone.” Image credits: Instagram / State Commission of the Penitentiary System of Baja California

3 common travel illnesses (and how to avoid them)

Nobody wants to fall sick when they’re on holidays but it happens and is actually quite common. Not every travel illness is foreseeable, but the most prevalent ones usually can be managed if you’re prepared and know what to look out for. Here are three of the most common illnesses travellers experience and what you can do to avoid them. Traveller’s diarrhoea It may be an unpleasant topic of conversation, but as diarrhoeais the most common travel sickness, it’s important to be prepared. It is estimated diarrhoeais experienced by almost half of travellers at some point on their holiday, but mainly by those visiting developing countries. It’s contracted by eating or drinking contaminated food and water and in severe cases can last for days. How to avoid it: Stick to bottled or purified water, freshly cooked meals and fruits and vegetables you can peel yourself. Talk to your doctor for antibiotics you can take in case you are struck with traveller’s diarrhoea. Motion sickness Whether it’s by boat, plane, or car, many travellers experience motion sickness. This occurs when your eyes see motion but your body doesn’t register it, leading to a conflict of the senses. It often results in nausea, vomiting, headaches, and sweating. How to avoid it: If flying, try to sit near the wings of plane. If cruising, get an outside cabin in the middle of ship, and if in a car, sit up front. Don’t play with your devices, as looking at a small screens often exacerbates the problem; instead try to look far to the horizon. Have a light meal before travelling and avoid spicy, greasy or rich foods. You can talk to your doctor about over-the-counter medication that can help motion sickness as well. Bug bites There are all sorts of infectious diseases like malaria, dengue, chikungunya and yellow fever you can pick up from bug bites, especially in developing nations. While you should always talk to your doctor about the types of vaccines you need to take for your travel destination, it is always advisable to protect against insect bites. How to avoid it: Apply insect repellent, wear long sleeves and pants where possible and try to avoid outside activity around dust and dawn when mosquitos are active. If sleeping outdoors, it is advisable to use curtain nettings. Image credits: Getty Images

Travel Tips

Vitamins and supplements: what you need to know before taking them

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/neelaveni-padayachee-1018709">Neelaveni Padayachee</a>, <a href="https://theconversation.com/institutions/university-of-the-witwatersrand-894">University of the Witwatersrand</a> and <a href="https://theconversation.com/profiles/varsha-bangalee-1253468">Varsha Bangalee</a>, <a href="https://theconversation.com/institutions/university-of-kwazulu-natal-1941">University of KwaZulu-Natal</a> If you were to open your medicine cabinet right now, there’s a fair chance that you’d find at least one bottle of vitamins alongside the painkillers, plasters and cough syrup. After all, people are definitely buying vitamins: in 2020, the global market for complementary and alternative medicines, which includes multivitamin supplements, had an estimated value of <a href="https://www.grandviewresearch.com/industry-analysis/complementary-alternative-medicine-market">US$82.27 billion</a>. The use of natural health products such as minerals and amino acids has <a href="https://journals.lww.com/nutritiontodayonline/Abstract/2007/03000/Why_People_Use_Vitamin_and_Mineral_Supplements.4.aspx">increased</a> – and continues to rise, partly driven by consumers’ buying habits during the COVID-19 pandemic. People <a href="https://www.businesslive.co.za/bd/companies/healthcare/2021-02-08-native-sales-of-sas-vitamins-and-nutritional-supplements-boom/">sought out</a> vitamins C and D, as well as zinc supplements, as potential preventive measures against the virus – even though the <a href="https://www.health.harvard.edu/blog/do-vitamin-d-zinc-and-other-supplements-help-prevent-covid-19-or-hasten-healing-2021040522310">evidence</a> for their efficacy was, and <a href="https://pubmed.ncbi.nlm.nih.gov/35888660/#:%7E:text=Concluding%2C%20available%20data%20on%20the,trials%20(RCTs)%20are%20inconsistent">remains</a>, inconclusive. Multivitamins and mineral supplements are easily accessible to consumers. They are often marketed for their health claims and benefits – sometimes unsubstantiated. But their potential adverse effects are not always stated on the packaging. Collectively, vitamins and minerals are known as micronutrients. They are essential elements needed for our bodies to function properly. Our bodies can only produce micronutrients in small amounts or not at all. We get the bulk of these nutrients <a href="https://www.iprjb.org/journals/index.php/IJF/article/view/1024">from our diets</a>. People usually buy micronutrients to protect against disease or as dietary “insurance”, in case they are not getting sufficient quantities from their diets. There’s a common perception that these supplements are harmless. But they can be dangerous at incorrect dosages. They provide a false sense of hope, pose a risk of drug interactions – and can delay more effective treatment. <h2>Benefits</h2> Vitamins are beneficial if taken for the correct reasons and as prescribed by your doctor. For example, folic acid supplementation in pregnant women has been shown to prevent neural tube defects. And individuals who reduce their intake of red meat without increasing legume consumption require a vitamin B6 supplement. But a worrying trend is increasing among consumers: intravenous vitamin therapy, which is often punted by celebrities and social media marketing. Intravenous vitamins, nutrients and fluids are administered at pharmacies as well as beauty spas, and more recently “<a href="https://www.health.harvard.edu/blog/drip-bar-should-you-get-an-iv-on-demand-2018092814899">IV bars</a>”. Users believe these treatments can quell a cold, slow the effects of ageing, brighten skin, fix a hangover or just make them feel well. Intravenous vitamin therapy was previously only used in medical settings to help patients who could not swallow, needed fluid replacements or had an electrolyte imbalance. However, the evidence to support other benefits of intravenous vitamin therapy is limited. No matter how you choose to get additional vitamins, there are risks. <h2>Warning bells</h2> Most consumers use multivitamins. But others take large doses of single nutrients, especially vitamin C, iron and calcium. As lecturers in pharmacy practice, we think it’s important to highlight the potential adverse effects of commonly used vitamins and minerals: <ul> <li> <a href="https://www.hsph.harvard.edu/nutritionsource/vitamin-a/">Vitamin A/retinol</a> is beneficial in maintaining good eye health. But it can cause toxicity if more than 300,000IU (units) is ingested. Chronic toxicity (hypervitaminosis) has been <a href="https://www.ncbi.nlm.nih.gov/books/NBK532916/">associated</a> with doses higher than 10,000IU a day. Symptoms include liver impairment, loss of vision and intracranial hypertension. It can cause birth defects in pregnant women. </li> <li> <a href="https://www.hsph.harvard.edu/nutritionsource/niacin-vitamin-b3/">Vitamin B3</a> is beneficial for nervous and digestive system health. At moderate to high doses it can cause peripheral vasodilation (widening or dilating of the blood vessels at the extremities, such as the legs and arms), resulting in skin flushing, burning sensation, pruritis (itchiness of the skin) and hypotension (low blood pressure). </li> <li> <a href="https://www.hsph.harvard.edu/nutritionsource/vitamin-b6/">Vitamin B6</a> is essential for brain development and in ensuring that the immune system remains healthy. But it can result in damage to the peripheral nerves, such as those in the hands and feet (causing a sensation of numbness and often referred to as pins and needles) at doses over 200mg/daily. </li> <li> <a href="https://www.hsph.harvard.edu/nutritionsource/vitamin-c/">Vitamin C</a> is an antioxidant and assists in the repair of body tissue. Taken in high doses it can cause kidney stones and interactions with drugs, such as the oncology drugs doxorubicin, methotrexate, cisplatin and vincristine. </li> <li> <a href="https://www.hsph.harvard.edu/nutritionsource/vitamin-d/">Vitamin D</a> is essential for bone and teeth development. At high doses it can cause hypercalcaemia (calcium level in the blood is above normal) that results in thirst, excessive urination, seizures, coma and death. </li> <li> <a href="https://www.hsph.harvard.edu/nutritionsource/calcium/#:%7E:text=Calcium%20is%20a%20mineral%20most,heart%20rhythms%20and%20nerve%20functions">Calcium</a> is essential for bone health, but can cause constipation and gastric reflux.

What are heart rate zones, and how can you incorporate them into your exercise routine?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/hunter-bennett-1053061">Hunter Bennett</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> If you spend a lot of time exploring fitness content online, you might have come across the concept of heart rate zones. Heart rate zone training has become more popular in recent years partly because of the boom in wearable technology which, among other functions, allows people to easily track their heart rates. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6537749/">Heart rate zones</a> reflect different levels of intensity during aerobic exercise. They’re most often based on a percentage of your maximum heart rate, which is the highest number of beats your heart can achieve per minute. But what are the different heart rate zones, and how can you use these zones to optimise your workout? <h2>The three-zone model</h2> While there are several models used to describe heart rate zones, the most common model in the scientific literature is the <a href="https://journals.humankinetics.com/view/journals/ijspp/9/1/article-p100.xml">three-zone model</a>, where the zones may be categorised as follows: <ul> <li> zone 1: 55%–82% of maximum heart rate </li> <li> zone 2: 82%–87% of maximum heart rate </li> <li> zone 3: 87%–97% of maximum heart rate. </li> </ul> If you’re not sure what your maximum heart rate is, it can be calculated using <a href="https://www.jacc.org/doi/full/10.1016/S0735-1097%2800%2901054-8">this equation</a>: 208 – (0.7 × age in years). For example, I’m 32 years old. 208 – (0.7 x 32) = 185.6, so my predicted maximum heart rate is around 186 beats per minute. There are also other models used to describe heart rate zones, such as the <a href="https://journals.humankinetics.com/view/journals/ijspp/14/8/article-p1151.xml">five-zone model</a> (as its name implies, this one has five distinct zones). These <a href="https://journals.humankinetics.com/view/journals/ijspp/9/1/article-p100.xml">models</a> largely describe the same thing and can mostly be used interchangeably. <h2>What do the different zones involve?</h2> The three zones are based around a person’s <a href="https://link.springer.com/article/10.2165/00007256-200939060-00003">lactate threshold</a>, which describes the point at which exercise intensity moves from being predominantly aerobic, to predominantly anaerobic. Aerobic exercise <a href="https://www.healthline.com/health/fitness-exercise/difference-between-aerobic-and-anaerobic">uses oxygen</a> to help our muscles keep going, ensuring we can continue for a long time without fatiguing. Anaerobic exercise, however, uses stored energy to fuel exercise. Anaerobic exercise also accrues metabolic byproducts (such as lactate) that increase fatigue, meaning we can only produce energy anaerobically for a short time. On average your lactate threshold tends to sit around <a href="https://www.tandfonline.com/doi/full/10.2147/OAJSM.S141657">85% of your maximum heart rate</a>, although this varies from person to person, and can be <a href="https://journals.physiology.org/doi/full/10.1152/japplphysiol.00043.2013">higher in athletes</a>. In the three-zone model, each zone loosely describes <a href="https://www.frontiersin.org/journals/physiology/articles/10.3389/fphys.2015.00295/full">one of three types of training</a>. Zone 1 represents high-volume, low-intensity exercise, usually performed for long periods and at an easy pace, well below lactate threshold. Examples include jogging or cycling at a gentle pace. Zone 2 is threshold training, also known as tempo training, a moderate intensity training method performed for moderate durations, at (or around) lactate threshold. This could be running, rowing or cycling at a speed where it’s difficult to speak full sentences. Zone 3 mostly describes methods of high-intensity interval training, which are performed for shorter durations and at intensities above lactate threshold. For example, any circuit style workout that has you exercising hard for 30 seconds then resting for 30 seconds would be zone 3. <h2>Striking a balance</h2> To maximise endurance performance, you need to strike a balance between doing enough training to elicit positive changes, while avoiding over-training, injury and burnout. While zone 3 is thought to produce the largest improvements in <a href="https://www.sciencedirect.com/science/article/pii/S1440244018309198">maximal oxygen uptake</a> – one of the best predictors of endurance performance and overall health – it’s also the most tiring. This means you can only perform so much of it before it becomes too much. Training in different heart rate zones improves <a href="https://citeseerx.ist.psu.edu/document?repid=rep1&type=pdf&doi=38c07018c0636422d9d5a77316216efb3c10164f">slightly different physiological qualities</a>, and so by spending time in each zone, you ensure a <a href="https://link.springer.com/article/10.1007/bf00426304">variety of benefits</a> for performance and health. <h2>So how much time should you spend in each zone?</h2> Most <a href="https://www.frontiersin.org/articles/10.3389/fspor.2023.1258585/full">elite endurance athletes</a>, including runners, rowers, and even cross-country skiers, tend to spend most of their training (around 80%) in zone 1, with the rest split between zones 2 and 3. Because elite endurance athletes train a lot, most of it needs to be in zone 1, otherwise they risk injury and burnout. For example, some runners accumulate <a href="https://journals.humankinetics.com/view/journals/ijsnem/22/5/article-p392.xml?content=pdf">more than 250 kilometres per week</a>, which would be impossible to recover from if it was all performed in zone 2 or 3. Of course, most people are not professional athletes. The <a href="https://www.who.int/news-room/fact-sheets/detail/physical-activity">World Health Organization</a> recommends adults aim for 150–300 minutes of moderate intensity exercise per week, or 75–150 minutes of vigorous exercise per week. If you look at this in the context of heart rate zones, you could consider zone 1 training as moderate intensity, and zones 2 and 3 as vigorous. Then, you can use heart rate zones to make sure you’re exercising to meet these guidelines. <h2>What if I don’t have a heart rate monitor?</h2> If you don’t have access to a heart rate tracker, that doesn’t mean you can’t use heart rate zones to guide your training. The three heart rate zones discussed in this article can also be prescribed based on feel using a simple <a href="https://onlinelibrary.wiley.com/doi/10.1111/j.1600-0838.2004.00418.x">10-point scale</a>, where 0 indicates no effort, and 10 indicates the maximum amount of effort you can produce. With this system, zone 1 aligns with a 4 or less out of 10, zone 2 with 4.5 to 6.5 out of 10, and zone 3 as a 7 or higher out of 10. Heart rate zones are not a perfect measure of exercise intensity, but can be a useful tool. And if you don’t want to worry about heart rate zones at all, that’s also fine. The most important thing is to simply get moving.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/228520/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/hunter-bennett-1053061">Hunter Bennett</a>, Lecturer in Exercise Science, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Flash droughts are becoming more common in Australia. What’s causing them?

<a href="https://theconversation.com/profiles/milton-speer-703091">Milton Speer</a>, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a> and <a href="https://theconversation.com/profiles/lance-m-leslie-437774">Lance M Leslie</a>, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a> <a href="https://www.drought.gov/what-is-drought/flash-drought">Flash droughts</a> strike suddenly and intensify rapidly. Often the affected areas are in drought after just weeks or a couple of months of well-below-average rainfall. They happen worldwide and are <a href="https://www.researchgate.net/publication/377274397_Flash_drought_A_state_of_the_science_review?_tp=eyJjb250ZXh0Ijp7ImZpcnN0UGFnZSI6InB1YmxpY2F0aW9uRG93bmxvYWQiLCJwYWdlIjoicHVibGljYXRpb24iLCJwcmV2aW91c1BhZ2UiOiJwdWJsaWNhdGlvbiJ9fQ#read">becoming more common</a>, including in Australia, due to global warming. Flash droughts can occur anywhere and at any time of the year. Last year, a flash drought <a href="https://www.abc.net.au/news/2023-10-20/dams-dry-up-as-drought-takes-hold-in-hunter-valley/102996364">hit the Upper Hunter</a> region of New South Wales, roughly 300 kilometres north-west of Sydney. These sudden droughts can have devastating economic, social and environmental impacts. The damage is particularly severe for agricultural regions heavily dependent on reliable rain in river catchments. One such region is the Upper Hunter Valley, the subject of our <a href="https://www.mdpi.com/2225-1154/12/4/49">new research</a>. We identified two climate drivers – the <a href="http://www.bom.gov.au/climate/about/?bookmark=enso">El Niño Southern Oscillation</a> and <a href="http://www.bom.gov.au/climate/about/?bookmark=iod">Indian Ocean Dipole</a>) – that became influential during this drought. In addition, the waning influence of a third climate driver, the <a href="http://www.bom.gov.au/climate/about/?bookmark=sam">Southern Annular Mode</a>), would typically bring rain to the east coast. However, this rain did not reach the Upper Hunter. Flash droughts are set to get more common as the world heats up. This year, a flash drought developed over western and central Victoria over just two months. While heavy rain this month in Melbourne ended the drought there, it continues in the west. <h2>What makes a flash drought different?</h2> Flash droughts differ from more slowly developing droughts. The latter result from extended drops in rainfall, such as the <a href="http://www.bom.gov.au/climate/drought/">drought affecting</a> parts of southwest Western Australia due to the much shortened winter wet season last year. Flash droughts develop when sudden large drops in rainfall coincide with above-average temperatures. They mostly occur in summer and autumn, as was the case for Asia and Europe in 2022. That year saw flash droughts appear across the northern hemisphere, such as the megadrought affecting China’s <a href="https://iopscience.iop.org/article/10.1088/1748-9326/acfe21">Yangtze river basin</a> and <a href="https://www.sciencedirect.com/science/article/pii/S2352340923000264?via%3Dihub">Spain</a>. The flash drought devastating the Upper Hunter from May to October 2023 developed despite the region being drought-free just one month earlier. At that stage, almost nowhere in NSW showed any sign of an impending drought. <figure class="align-center "><img src="https://images.theconversation.com/files/586776/original/file-20240409-18-n82npo.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/586776/original/file-20240409-18-n82npo.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=276&fit=crop&dpr=1 600w, https://images.theconversation.com/files/586776/original/file-20240409-18-n82npo.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=276&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/586776/original/file-20240409-18-n82npo.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=276&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/586776/original/file-20240409-18-n82npo.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=347&fit=crop&dpr=1 754w, https://images.theconversation.com/files/586776/original/file-20240409-18-n82npo.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=347&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/586776/original/file-20240409-18-n82npo.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=347&fit=crop&dpr=3 2262w" alt="Maps of drought conditions in NSW in April 2023 compared to the next six months" /><figcaption>NSW Department of Primary Industries’ combined drought indicator in April 2023 (a) and combined drought indicator for May–October 2023 (b) show how rapidly a flash drought developed in the Upper Hunter region. Milton Speer et al 2024, using NSW Department of Primary Industries' data</figcaption></figure> The flash drought greatly affected agricultural production in the Upper Hunter region, due to the region’s reliance on water from rivers. Low rainfall in river catchments means less water for crops and pasture. It also dries up drinking water supplies. Flash droughts are characterised by abrupt periods of low rainfall leading to rapid drought onset, particularly when accompanied by above-average temperatures. Higher temperatures increase both the evaporation of water from the soil and transpiration from plants (evapotranspiration). This causes soil moisture to drop rapidly. <h2>The Upper Hunter drought is part of a trend</h2> Flash droughts will be more common in the future. That’s because higher temperatures will more often coincide with dry conditions, as relative humidity falls <a href="https://www.researchgate.net/publication/377274397_Flash_drought_A_state_of_the_science_review_tp=eyJjb250ZXh0Ijp7ImZpcnN0UGFnZSI6InB1YmxpY2F0aW9uRG93bmxvYWQiLCJwYWdlIjoicHVibGljYXRpb24iLCJwcmV2aW91c1BhZ2UiOiJwdWJsaWNhdGlvbiJ9fQ#read">across many parts</a> of Australia and globally.

Milton Speer et al 2024</figcaption></figure> In south-east and south-west Australia, flash droughts can also occur in winter. In May 2023 rainfall over south-east Australia dropped abruptly. The much lower rainfall continued until November in the Upper Hunter. Over this same period, mean maximum temperatures in the region were the highest on record, increasing the loss of moisture through evapotranspiration. The result was a flash drought. While flash droughts occurred in other parts of south-east Australia, we focused on the Upper Hunter as it remained in drought the longest. <h2>What were the climate drivers of this drought?</h2> We used machine-learning techniques to identify the key climate drivers of the drought. We found the dominant driver of the flash drought was global warming, modulated by the phases of the three major climate drivers in our region, the El Niño Southern Oscillation, Indian Ocean Dipole and the Southern Annular Mode. From 2020 to 2022, the first two drivers became favourable for rain in the Upper Hunter in late winter through spring, before changing phase to one supporting drought over south-east Australia. Meanwhile, the Southern Annular Mode remained mostly positive, meaning rain-bearing westerly winds and weather fronts had moved to middle and higher latitudes of the southern hemisphere, away from Australia’s south-east coast. Combined, the impact of global warming with the three climate drivers made rainfall much more variable. The net result was an atmospheric environment highly conducive to a flash drought appearing anywhere in south-east Australia. <figure class="align-right zoomable"><a href="https://images.theconversation.com/files/586248/original/file-20240405-16-ti5j3m.png?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/586248/original/file-20240405-16-ti5j3m.png?ixlib=rb-1.1.0&q=45&auto=format&w=237&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/586248/original/file-20240405-16-ti5j3m.png?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=464&fit=crop&dpr=1 600w, https://images.theconversation.com/files/586248/original/file-20240405-16-ti5j3m.png?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=464&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/586248/original/file-20240405-16-ti5j3m.png?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=464&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/586248/original/file-20240405-16-ti5j3m.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=583&fit=crop&dpr=1 754w, https://images.theconversation.com/files/586248/original/file-20240405-16-ti5j3m.png?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=583&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/586248/original/file-20240405-16-ti5j3m.png?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=583&fit=crop&dpr=3 2262w" alt="Map of Upper Hunter region showing drought indicators in December 2023" /></a><figcaption>Intense drought conditions continued in the Upper Hunter in December 2023. Milton Speer et al 2024</figcaption></figure> <h2>Victoria, too, fits the global warming pattern</h2> As for the flash drought that developed in early 2024 over western and central Victoria, including Melbourne, it continues in parts of <a href="http://www.bom.gov.au/climate/drought/#msdynttrid=_ytsVsw1a3IFZ7xGCnQz8mw1Gum_n_0JUdQyt2hUVCo">western Victoria</a>. The flash drought followed very high January rainfall (top 5% of records) dropping rapidly to very low rainfall (bottom 5%) in February and March. It was the <a href="http://www.bom.gov.au/climate/maps/rainfall/?variable=rainfall&map=decile&period=2month&region=vc&year=2024&month=03&day=31">driest February-March period</a> on record for Melbourne and south-west Victoria. At the beginning of April, a storm front <a href="https://www.9news.com.au/national/severe-weather-storm-warning-for-victoria-and-melbourne-easter-monday/41d5d383-b70d-4d36-a649-38632bc607de">brought heavy rainfall</a> over an 18-hour period to central Victoria, including Melbourne. The rains ended the flash drought in these areas, but it continues in parts of western Victoria, which missed out on the rain. The pattern of the 2024 flash drought in Victoria typifies the increasing trend under global warming of long dry periods, interspersed by short, heavy rainfall events. <img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/227052/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/milton-speer-703091">Milton Speer</a>, Visiting Fellow, School of Mathematical and Physical Sciences, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a> and <a href="https://theconversation.com/profiles/lance-m-leslie-437774">Lance M Leslie</a>, Professor, School of Mathematical And Physical Sciences, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.
