Why do I get so anxious after drinking? Here’s the science behind ‘hangxiety’

<a href="https://theconversation.com/profiles/blair-aitken-1510537">Blair Aitken</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a> and <a href="https://theconversation.com/profiles/rebecca-rothman-2231560">Rebecca Rothman</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a> You had a great night out, but the next morning, anxiety hits: your heart races, and you replay every conversation from the night before in your head. This feeling, known as hangover anxiety or “<a href="https://adf.org.au/insights/what-is-hangxiety/">hangxiety</a>”, <a href="https://onlinelibrary.wiley.com/doi/10.1002/hup.2623">affects around 22%</a> of social drinkers. While for some people, it’s mild nerves, for others, it’s a wave of anxiety that feels impossible to ride out. The “Sunday scaries” may make you feel panicked, filled with dread and unable to relax. Hangover anxiety can make even simple tasks feel overwhelming. Here’s why it happens, and what you can do about it. <h2>What does alcohol do to our brains?</h2> A hangover is the body’s way of recovering after drinking alcohol, bringing with it a range of symptoms. <a href="https://www.mdpi.com/2077-0383/10/23/5691">Dehydration and disrupted sleep</a> play a large part in the pounding headaches and nausea many of us know too well after a big night out. But hangovers aren’t just physical – there’s a strong mental side too. Alcohol is a nervous system depressant, meaning it alters how certain chemical messengers (or neurotransmitters) behave in the brain. Alcohol relaxes you by increasing <a href="https://my.clevelandclinic.org/health/articles/22857-gamma-aminobutyric-acid-gaba">gamma-aminobutyric acid</a> (GABA), the neurotransmitter that makes you feel calm and lowers inhibitions. It decreases <a href="https://my.clevelandclinic.org/health/articles/22839-glutamate">glutamate</a> and this also slows down your thoughts and helps ease you into a more relaxed state. Together, this interaction affects your mood, emotions and alertness. This is why when we drink, we often feel more sociable, carefree and willing to let our guard down. As the effects of the alcohol wear off, your brain works to rebalance these chemicals by <a href="https://www.sciencedirect.com/science/article/pii/S0191886918305762">reducing GABA and increasing glutamate</a>. This shift has the opposite effect of the night before, causing your brain to become more excitable and overstimulated, which can lead to feelings of anxiety. So why do some people get hangxiety, while others don’t? There isn’t one clear answer to this question, as several factors can play a role in whether someone experiences hangover-related anxiety. <h2>Genes play a role</h2> For some, a hangover is simply a matter of how much they drank or how hydrated they are. But genetics may also play a significant role. <a href="https://onlinelibrary.wiley.com/doi/10.1111/add.12699">Research</a> shows your genes can explain almost half the reason why you wake up feeling hungover, while your friend might not. Because genes influence how your body processes alcohol, some people may experience more intense hangover symptoms, such as headaches or dehydration. These stronger physical effects can, in turn, <a href="https://onlinelibrary.wiley.com/doi/pdf/10.1002/hup.2623">trigger anxiety during a hangover</a>, making you more susceptible to “hangxiety.” <h2>Do you remember what you said last night?</h2> But one of the most common culprits for feeling anxious the next day is often <a href="https://journals.sagepub.com/doi/pdf/10.1177/0091450915604988">what you do while drinking</a>. Let’s say you’ve had a big night out and you can’t quite recall a conversation you had or something you did. Maybe you acted in ways that you now regret or feel embarrassed about. You might fixate on these thoughts and get trapped in a cycle of worrying and rumination. This cycle can be hard to break and can make you feel more anxious. <a href="https://doi.org/10.1016/j.addbeh.2023.107619">Research</a> suggests people who already struggle with feelings of anxiety in their day-to-day lives are especially vulnerable to hangxiety. Some people drink alcohol to unwind after a stressful day or to make themselves feel more comfortable at social events. This often leads to <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9756407">heavier consumption</a>, which can make hangover symptoms more severe. It can also begin a cycle of drinking to feel better, making hangxiety even harder to escape. <h2>Preventing hangover anxiety</h2> The best way to prevent hangxiety is to limit your alcohol consumption. The <a href="https://adf.org.au/reducing-risk/alcohol/alcohol-guidelines">Australian guidelines</a> recommend having no more than ten standard drinks per week and no more than four standard drinks on any one day. Generally, the more you drink, the more intense your hangover symptoms might be, and the worse you are likely to feel. Mixing other drugs with alcohol can also increase the risk of hangxiety. This is especially true for party drugs, such as ecstasy or MDMA, that give you a temporary high but can lead to anxiety as they wear off and you are <a href="https://adf.org.au/insights/drug-comedowns">coming down</a>. If you do wake up feeling anxious: <ul> <li> focus on the physical recovery to help ease the mental strain </li> <li> drink plenty of water, eat a light meal and allow yourself time to rest </li> <li> try <a href="https://www.headspace.com/mindfulness/mindfulness-101">mindfulness meditation</a> or deep breathing exercises, especially if anxiety keeps you awake or your mind races </li> <li> consider journalling. This can help re-frame anxious thoughts, put your feelings into perspective and encourage self-compassion </li> <li> talk to a close friend. This can provide a safe space to express concerns and feel less isolated. </li> </ul> Hangxiety is an unwelcome guest after a night out. Understanding why hangxiety happens – and how you can manage it – can make the morning after a little less daunting, and help keep those anxious thoughts at bay.<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/240991/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/blair-aitken-1510537">Blair Aitken</a>, Postdoctoral Research Fellow in Psychopharmacology, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a> and <a href="https://theconversation.com/profiles/rebecca-rothman-2231560">Rebecca Rothman</a>, PhD Candidate in Clinical Psychology, School of Health Sciences, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

What causes the itch in mozzie bites? And why do some people get such a bad reaction?

<a href="https://theconversation.com/profiles/cameron-webb-6736">Cameron Webb</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> Are you one of these people who loathes spending time outdoors at dusk as the weather warms and mosquitoes start biting? Female mosquitoes <a href="https://www.annualreviews.org/content/journals/10.1146/annurev-ento-120811-153618">need blood</a> to develop their eggs. Even though they take a tiny amount of our blood, they can leave us with itchy red lumps that can last days. And sometimes something worse. So why does our body react and itch after being bitten by a mosquito? And why are some people more affected than others? <h2>What happens when a mosquito bites?</h2> Mosquitoes are attracted to warm blooded animals, including us. They’re attracted to the <a href="https://www.cambridge.org/core/journals/bulletin-of-entomological-research/article/abs/role-of-carbon-dioxide-in-hostfinding-by-mosquitoes-diptera-culicidae-a-review/2506B86EF63852B2D02EC3FCEE1E3B8B">carbon dioxide</a> we exhale, our body temperatures and, most importantly, <a href="https://www.abc.net.au/news/2024-11-08/mosquitoes-climate-change-skin/104548122">the smell of our skin</a>. The <a href="https://www.cell.com/trends/parasitology/abstract/S1471-4922(21)00237-3">chemical cocktail</a> of odours from bacteria and sweat on our skin <a href="https://www.cell.com/current-biology/fulltext/S0960-9822(23)00532-8">sends out a signal</a> to hungry mosquitoes. <a href="https://www.sciencedirect.com/science/article/pii/S2667114X21000522">Some people’s</a> skin smells more appealing to mosquitoes, and they’re more likely to be bitten than others. Once the mosquito has made its way to your skin, things get a little gross. The mosquito pierces your skin with their “proboscis”, their feeding mouth part. But the proboscis isn’t a single, straight, needle-like tube. There are multiple tubes, <a href="https://www.npr.org/sections/health-shots/2016/06/07/480653821/watch-mosquitoes-use-6-needles-to-suck-your-blood">some designed</a> for sucking and some for spitting. Once their mouth parts have been inserted into your skin, the mosquito will inject some saliva. This contains a mix of chemicals that gets the blood flowing better. There has even been a suggestion that future medicines could be inspired by the <a href="https://www.sydney.edu.au/news-opinion/news/2018/03/29/mosquito-saliva-vital-to-the-discovery-of-future-drugs.html">anti-blood clotting properties</a> of mosquito saliva. It’s not the stabbing of our skin by the mosquito’s mouth parts that hurts, it’s the mozzie spit our bodies don’t like. <h2>Are some people allergic to mosquito spit?</h2> Once a mosquito has injected their saliva into our skin, a variety of reactions can follow. For the lucky few, nothing much happens at all. For most people, and irrespective of the type of mosquito biting, <a href="https://www.frontiersin.org/journals/immunology/articles/10.3389/fimmu.2022.1024559/full">there is some kind of reaction</a>. Typically there is <a href="https://www.sciencedirect.com/science/article/abs/pii/S0161589023002304?via%3Dihub">redness and swelling of the skin</a> that appears within a few hours, but often more quickly, after just a few minutes. Occasionally, the reaction can cause pain or discomfort. Then comes the <a href="https://www.abc.net.au/news/health/2023-01-20/mosquito-bites-itchy-calamine-heat-ice-antihistamine-toothpaste/101652608">itchiness</a>. Some people do suffer severe reactions to mosquito bites. It’s a condition often referred to as “<a href="https://www.webmd.com/allergies/what-is-skeeter-syndrome">skeeter syndrome</a>” and is an allergic reaction caused by the protein in the mosquito’s saliva. This can cause large areas of swelling, blistering and fever. The chemistry of mosquito spit hasn’t really been well studied. But it has been shown that, for those who do suffer allergic reactions to their bites, the <a href="https://www.sciencedirect.com/science/article/abs/pii/S0091674904022183">reactions may differ</a> depending on the type of mosquito biting. We all probably get more tolerant of mosquito bites as we get older. Young children are certainly more likely to suffer more following mosquito bites. But as we get older, the reactions are less severe and may pass quickly without too much notice. <h2>How best to treat the bites?</h2> Research into treating bites <a href="https://linkinghub.elsevier.com/retrieve/pii/S0161589023002304">has yet to provide</a> a single easy solution. There are many <a href="https://www.healthline.com/health/outdoor-health/home-remedies-for-mosquito-bites">myths and home remedies</a> about what works. But there is little scientific evidence supporting their use. The best way to treat mosquito bites is by applying a cold pack to reduce swelling and to keep the skin clean to avoid any secondary infections. Antiseptic creams and lotions may also help. There is some evidence that <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC10309056/">heat may alleviate</a> some of the discomfort. It’s particularly tough to keep young children from scratching at the bite and breaking the skin. This can form a nasty scab that may end up being worse than the bite itself. Applying an anti-itch cream may help. If the reactions are severe, <a href="https://www.healthdirect.gov.au/insect-bites-and-stings">antihistamine medications</a> may be required. <h2>To save the scratching, stop the bites</h2> Of course, it’s better not to be bitten by mosquitoes in the first place. Topical <a href="https://theconversation.com/insect-repellents-work-but-there-are-other-ways-to-beat-mosquitoes-without-getting-sticky-171805">insect repellents</a> are a safe, effective and affordable way to reduce mosquito bites. Covering up with loose fitted long sleeved shirts, long pants and covered shoes also provides a physical barrier. <a href="https://theconversation.com/are-mosquito-coils-good-or-bad-for-our-health-88548">Mosquito coils and other devices</a> can also assist, but should not be entirely relied on to stop bites. There’s another important reason to avoid mosquito bites: millions of people around the world suffer from mosquito-borne diseases. More than <a href="https://www.who.int/news-room/fact-sheets/detail/malaria">half a million people die</a> from malaria each year. In Australia, <a href="https://journals.plos.org/plospathogens/article?id=10.1371/journal.ppat.1005070">Ross River virus</a> infects more than 5,000 people every year. And in recent years, there have been cases of serious illnesses caused by <a href="https://www.science.org/content/article/how-rains-pigs-and-waterbirds-fueled-shocking-disease-outbreak-australia">Japanese encephalitis</a> and <a href="https://www.frontiersin.org/journals/public-health/articles/10.3389/fpubh.2023.1256149/full">Murray Valley encephalitis</a> viruses. <a href="https://theconversation.com/profiles/cameron-webb-6736">Cameron Webb</a>, Clinical Associate Professor and Principal Hospital Scientist, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

"What did we do?": Bride shares heartbroken reaction to empty wedding

A bride has recalled the devastating moment she made a grand entrance to her wedding, only to discover almost no guests showed up. Kalina Marie took to TikTok to share the gut-wrenching video of the moment her and her new husband Shane stepped inside the lavishly decorated hall with their son, as they tried to come to terms with the fact that only a handful of people showed to celebrate with them. “This is our entrance to our Masquerade ball,” Ms Marie, who is from Oregon in the US, wrote in the caption of her clip, which has since amassed over seven million views. “The Masquerade ball that I have talked EXCESSIVELY about for the last 10 months. The same ball that I not only digitally invited over 75 people to. But ALSO spent money to send 25 beautiful invitations out to." “FIVE PEOPLE SHOWED UP!!!!!!! Like, are you kidding me!?!? As you see in the video, we enter the venue. And no one is there. The invite said 1pm. My mum messaged me at 1:15pm that no one was there. My husband and I finally showed up at 2 o’clock, to five people, in a venue planned for 40.” <div class="embed" style="font-size: 16px; box-sizing: inherit; margin: 0px; padding: 0px; border: 0px; vertical-align: baseline; outline: currentcolor !important;"><iframe class="embedly-embed" style="box-sizing: inherit; margin: 0px; padding: 0px; border-width: 0px; border-style: none; vertical-align: baseline; width: 600px; max-width: 100%; outline: currentcolor !important;" title="tiktok embed" src="https://cdn.embedly.com/widgets/media.html?src=https%3A%2F%2Fwww.tiktok.com%2Fembed%2Fv2%2F7433899067664551198&display_name=tiktok&url=https%3A%2F%2Fwww.tiktok.com%2F%40kalina_marie_23%2Fvideo%2F7433899067664551198&image=https%3A%2F%2Fp16-pu-sign-useast8.tiktokcdn-us.com%2Fobj%2Ftos-useast8-p-0068-tx2%2F7f29587f56a44788903eea92cd974c62_1730839526%3Flk3s%3Db59d6b55%26x-expires%3D1731499200%26x-signature%3DbUQfTW%252F8BrelG0Dy5rCNSzBBbiQ%253D%26shp%3Db59d6b55%26shcp%3D-&key=5b465a7e134d4f09b4e6901220de11f0&type=text%2Fhtml&schema=tiktok" width="340" height="700" frameborder="0" scrolling="no" allowfullscreen="allowfullscreen"></iframe></div> She said she “dreamt” that she would walk into a bunch of people “hooting and hollering” for them, but instead ended up having to “hold herself together” because she had “no idea” how to deal with her venue being almost completely empty. “All the wasted food and drinks,” Ms Marie continued. “All the empty tables and chairs. Every moment of my reception changed to adapt.” “It just makes me think, like, why? What did we do? Am I that bad of a person? What did my husband ever do to deserve any of this?” she questioned. “Why couldn’t we matter enough for people to show up?” She revealed that it makes her “sick” that she still has “friends” who haven’t even messaged her to congratulate her or tell her why they didn’t come, adding, “I honestly can’t wrap my head around this yet.” The heart-breaking video quickly wrapped up millions of views and comments, with many empathising with the new bride, with one person writing, "This hurts my heart for you." Thousands of others tried to lighten the mood, praising Ms Marie for how beautiful she looked and vowing to attend a do-over wedding. “NAH, RE-DO THIS. WE ALL SHOWING UP,” read a top comment, while another wrote, “Let’s do it over. This time invite me and the rest of us. We’ll show up and out. I love you beautiful and congratulations!!” Image credits: TikTok

Relationships

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

<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.

How do children learn good manners?

<a href="https://theconversation.com/profiles/sophia-waters-501831">Sophia Waters</a>, <a href="https://theconversation.com/institutions/university-of-new-england-919">University of New England</a> Ensuring kids have manners is a <a href="https://tidsskrift.dk/sss/article/view/135074">perennial preoccupation</a> for parents and caregivers. How, then, do you teach good manners to children? Modelling good manners around the home and in your own interaction with others is obviously crucial. But there’s a clear <a href="https://tidsskrift.dk/sss/article/view/135074">uniting theme</a> when it comes to manners in Australia: in Australian English, good manners centre on honouring personal autonomy, egalitarianism and not appearing to tell people what to do. <h2>Which manners matter most in Australia?</h2> Some of the most important manners in Australian English are behavioural edicts that focus on particular speech acts: greeting, requesting, thanking and apologising. These speech acts have a <a href="https://tidsskrift.dk/sss/article/view/135074/179857">set of words</a> associated with them: <ul> <li>hello</li> <li>hi</li> <li>may I please…?</li> <li>could I please…?</li> <li>thank you</li> <li>ta</li> <li>sorry</li> <li>excuse me.</li> </ul> Good manners make people feel comfortable in social situations by adding predictability and reassurance. They can act as signposts in interactions. Anglo cultures place a lot of weight on <a href="https://www.sciencedirect.com/science/article/pii/S0378216612001014">egalitarianism</a>, personal autonomy and ensuring we don’t <a href="https://www.google.com.au/books/edition/English/d-d5AAAAIAAJ?hl=en">tell people what to do</a>. If you want to get someone to do something for you – pass you a pen, for example – you frame the request as a question to signal that you’re not telling them what to do. You’ll also add one of the main characters in Anglo politeness: the magic word, “<a href="https://www.academia.edu/20312114/Lige_a_Danish_magic_word_An_ethnopragmatic_analysis">please</a>”. This framing recognises you don’t expect or demand compliance. You’re acknowledging the other person as an autonomous individual who can do what they want. If the person does the thing you’ve asked, the next step is to say “thank you” to recognise the other person’s autonomy. You’re acknowledging they didn’t have to help just because you asked. <h2>The heavy hitters</h2> The words “please” and “thank you” are such heavy hitters in Australian English good manners, they’re two of the words that language learners and migrants <a href="https://www.tandfonline.com/doi/epdf/10.1080/10408340308518247?needAccess=true">learn first</a>. They can help soften the impact of your words. Think, for example, of the difference between “no” and “no, thank you”. Of course, there are times when “no” is a full sentence. But what if someone offered you a cup of tea and you replied “no” without its concomitant “thank you” to soften your rejection and acknowledge this offer didn’t have to be made? Don’t be surprised if they think you sound a bit rude. The other big players in Australian English good manners are “sorry” and “excuse me”. Much like in <a href="https://www.instagram.com/p/BZ1Eid0gnLV/">British English</a>, the Australian “sorry” means many things. These can preface an intrusion on someone’s personal space, like before squeezing past someone in the cinema, or on someone’s speaking turn. Interrupting or talking over someone else is often heavily frowned on in Australian English because it is often interpreted as disregarding what the other person has to say. But in some cultures, <a href="https://www.sciencedirect.com/science/article/pii/S0346251X14001365">such as French</a>, this conversational style is actively encouraged. And some languages and cultures <a href="https://www.sciencedirect.com/science/article/pii/S038800011830069X?via%3Dihub">have different conventions</a> around what good manners look like around strangers versus with family. Good manners involve saying certain words in predictable contexts. But knowing what these are and when to use them demonstrates a deeper cultural awareness of what behaviours are valued. <h2>How do children learn manners?</h2> As part of my <a href="https://tidsskrift.dk/sss/article/view/135074">research</a>, I’ve analysed parenting forum posts about “good manners”. Some believe good manners should be effortless; one parent said: <blockquote> Good manners shouldn’t be something that a child has to think about […] teach them correctly at home from day one, manners become an integral part of the way they view things. </blockquote> Another forum user posited good modelling was the key, saying: <blockquote> the parent has to lead by example, rather than forcing a child to say one or the other. </blockquote> One <a href="https://pubmed.ncbi.nlm.nih.gov/38777043/">study</a>, which involved analysis of more than 20 hours of videorecorded family dinner interactions collected in Italy, found mealtimes are also sites where parents control their children’s conduct “through the micro-politics of good manners.” <blockquote> By participating in mealtime interactions, children witness and have the chance to acquire the specific cultural principles governing bodily conduct at the table, such as ‘sitting properly’, ‘eating with cutlery’, and ‘chewing with mouth closed’. Yet, they are also socialised to a foundational principle of human sociality: one’s own behavior must be self-monitored according to the perspective of the generalised Other. </blockquote> In Australian English, that means regulating your behaviour to make sure you don’t do something that could be seen as “rude”. As I argued in a 2012 <a href="https://www.sciencedirect.com/science/article/abs/pii/S0378216612000410">paper</a>: <blockquote> While child socialisation in Anglo culture involves heavy discouragement of rudeness, French does not have a direct equivalent feature […] French children are taught ça ne se fait pas, ‘that is not done’. Where the French proscribe the behaviours outright, the Anglos […] appeal to the image one has of oneself in interpersonal interactions. </blockquote> In Anglo English, the penalties for breaches could be other people’s disapproval and hurting their feelings. <h2>Why are good manners important?</h2> Good manners affect our interactions with others and help us build positive relationships. Fourteenth century English bishop and educator, William of Wykeham, declared that “<a href="https://www.oxfordreference.com/display/10.1093/oi/authority.20110803100131244#:%7E:text=Manners%20maketh%20man%20proverbial%20saying,Winchester%20and%20chancellor%20of%20England">manners maketh the man</a>”. John Hopkins University Professor <a href="https://ii.library.jhu.edu/2018/12/11/in-memory-of-p-m-forni-the-case-for-civility-in-the-classroom-and-beyond/">Pier Forni</a> called them a “precious life-improvement tool.” The “Good Manners” <a href="https://education.qld.gov.au/about-us/history/history-topics/good-manners-chart">chart</a>, based on a set of rules devised by the Children’s National guild of Courtesy in UK primary schools in 1889, was issued to Queensland primary schools until the 1960s. It tells kids to remember the golden rule to “always do to others as you would wish them to do to you if you were in their place.” Good manners form part of the bedrock for human sociality. Childhood is when we give kids foundational training on interacting with others and help them learn how to be a culturally competent member of a society.<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/237133/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/sophia-waters-501831">Sophia Waters</a>, Senior Lecturer in Writing, <a href="https://theconversation.com/institutions/university-of-new-england-919">University of New England</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

"I’m coming home from a party, and I don’t want to end up getting arrested": do driving apps help people break road rules?

<a href="https://theconversation.com/profiles/verity-truelove-1237331">Verity Truelove</a>, <a href="https://theconversation.com/institutions/university-of-the-sunshine-coast-1068">University of the Sunshine Coast</a>; <a href="https://theconversation.com/profiles/michelle-nicolls-1299069">Michelle Nicolls</a>, <a href="https://theconversation.com/institutions/university-of-the-sunshine-coast-1068">University of the Sunshine Coast</a>, and <a href="https://theconversation.com/profiles/oscar-oviedo-trespalacios-1417150">Oscar Oviedo-Trespalacios</a>, <a href="https://theconversation.com/institutions/delft-university-of-technology-1040">Delft University of Technology</a> Apps such as Google Maps, Apple Maps and Waze can tell drivers when they are approaching speed cameras or random breath testing stations. Countries such as Germany, France and Switzerland have banned apps from displaying these enforcement locations. But what effect are these apps having in Australia – are they helping drivers break road rules? Our new <a href="https://www.sciencedirect.com/science/article/pii/S0925753524002972">paper</a>, published in the journal Safety Science, examined this question. We found this technology can, in some cases, contribute to people thinking they are invincible on the roads. However, we also found they can sometimes help people drive more safely. <h2>Being made aware of enforcement can help road safety</h2> We conducted focus groups and interviews with a total of 58 drivers from Queensland, to understand how the use of this technology influences perceptions of being caught for breaking road rules. One driver told us: "If I know it’s coming up, I’ll put my phone down. If I was, say, texting or checking something, but then like once a good few 100 metres away, I sort of pick it up again, depending though." Another said: "It sort of depends where I am driving, I guess. Like, if I am driving on a country road and there is a speed camera there I would probably slow down for the speed camera and then sort of speed up again once I am sort of past that; it sort of depends on the circumstances." We also found that, for some people, being made aware of enforcement locations can help drivers better regulate their speed. This helped them comply with road rules more consistently. Waze also shows the speed limit in the area, which further assisted some drivers to stick to the speed limit. One driver told us: "I’m a bit careful if I just look at the speedo and just double check that I’m on the right amount of speed." Another said: "It just gives you a warning like, ‘OK, you need to check your speed.’ Just to double-check you’re going on the right speed perhaps or when it’s a camera coming up." <h2>Concerning behaviours</h2> Concerningly, we also found some drivers who use these apps are looking at and touching their screens more than they otherwise would. This can distract drivers and increase their <a href="https://www.sciencedirect.com/science/article/pii/S0925753524001097">risk of crashing</a>. One driver told us they post traffic updates on the app they use while driving, “which I know is wrong.” Another said: "Just hit the button on the phone. Just two steps after I go past the camera." Another driver told us: "It’s so helpful […] Especially if it’s, say, late night and I’m coming home from a party, and I don’t want to end up getting arrested." One driver said: "I probably feel slightly more invincible, which is probably not a good thing." When asked why these apps are used, one driver said: "I guess the drug and the drink-driving." <h2>Apps can help and hinder road safety</h2> We know breaking road rules significantly contributes to <a href="https://www.who.int/teams/social-determinants-of-health/safety-and-mobility/global-status-report-on-road-safety-2023">crashes and road fatalities</a>, with deaths on Australian roads continuing to <a href="https://www.bitre.gov.au/publications/ongoing/road_deaths_australia_monthly_bulletins">increase</a> over time. On the one hand, when drivers are aware of enforcement measures like cameras and police, they are more likely to stop breaking the rules in those areas. That’s particularly true for behaviours such as speeding and using a phone while driving, we found. Using apps that flag where cameras and police are located also means drivers would be more exposed to enforcement activities than they otherwise would be on a normal drive. On the other hand, our results suggest some drivers are using these applications to break road rules more often in places where they think they won’t be caught. These apps are also not always completely accurate. For instance, even though Waze can display some police operation locations such as roadside breath testing, it can’t capture all on-road police activities. Further, camera locations are not always up to date or accurate. <h2>Weighing benefits against risks</h2> While these apps do have some benefits, it’s important to weigh these against the risks. It’s also important to recognise traffic enforcement isn’t just there to make you comply with road rules at a specific point; it is meant to remind you of the constant risk of being caught and to encourage consistent rule compliance. The goal is to ensure that drivers are following the traffic rules across the entire network, not just in isolated spots. With road fatalities at some of the <a href="https://www.bitre.gov.au/publications/ongoing/road_deaths_australia_monthly_bulletins">highest rates we’ve seen in recent years</a>, we need everyone to work together to stop more preventable deaths and injuries.<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/237664/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/verity-truelove-1237331">Verity Truelove</a>, Senior Research Fellow in Road Safety Research, <a href="https://theconversation.com/institutions/university-of-the-sunshine-coast-1068">University of the Sunshine Coast</a>; <a href="https://theconversation.com/profiles/michelle-nicolls-1299069">Michelle Nicolls</a>, PhD Candidate, <a href="https://theconversation.com/institutions/university-of-the-sunshine-coast-1068">University of the Sunshine Coast</a>, and <a href="https://theconversation.com/profiles/oscar-oviedo-trespalacios-1417150">Oscar Oviedo-Trespalacios</a>, A/Professor Responsible Risk Management, <a href="https://theconversation.com/institutions/delft-university-of-technology-1040">Delft University of Technology</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Why do organisations still struggle to protect our data? We asked 50 professionals on the privacy front line

<a href="https://theconversation.com/profiles/jane-andrew-10314">Jane Andrew</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/dr-penelope-bowyer-pont-1550191">Dr Penelope Bowyer-Pont</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>, and <a href="https://theconversation.com/profiles/max-baker-25553">Max Baker</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> More of our personal data is now collected and stored online than ever before in history. The rise of data breaches should unsettle us all. At an individual level, data breaches can compromise our privacy, cause harm to our finances and mental health, and even enable identity theft. For organisations, the repercussions can be equally severe, often resulting in major financial losses and brand damage. Despite the increasing importance of protecting our personal information, doing so remains fraught with challenges. As part of a <a href="http://www.doi.org/10.25910/psq3-q365">comprehensive study</a> of data breach notification practices, we interviewed 50 senior personnel working in information security and privacy. Here’s what they told us about the multifaceted challenges they face. <h2>What does the law actually say?</h2> Data breaches occur whenever personal information is accessed or disclosed without authorisation, or even lost altogether. <a href="https://www.abc.net.au/news/2024-06-20/optus-hack/104002682">Optus</a>, <a href="https://www.abc.net.au/news/2022-11-09/medibank-data-release-dark-web-hackers/101632088">Medibank</a> and <a href="https://www.afr.com/technology/canva-criticised-after-data-breach-exposed-139m-user-details-20190526-p51r8i">Canva</a> have all experienced high-profile incidents in recent years. Under Australia’s <a href="https://www8.austlii.edu.au/cgi-bin/viewdb/au/legis/cth/consol_act/pa1988108/">privacy laws</a>, organisations aren’t allowed to sweep major cyber attacks under the rug. They have to notify both the regulator – the Office of the Australian Information Commissioner (OAIC) – and any affected individuals of breaches that are likely to result in “<a href="https://www8.austlii.edu.au/cgi-bin/viewdb/au/legis/cth/consol_act/pa1988108/#:%7E:text=Whether%20access%20or%20disclosure%20would%20be%20likely%2C%20or%20would%20not%20be%20likely%2C%20to%20result%20in%20serious%20harm%2D%2Drelevant%20matters%20%C2%A0">serious harm</a>”. But according to the organisational leaders we interviewed, this poses a tricky question. How do you define serious harm? Interpretations of what “serious harm” actually means – and how likely it is to occur – vary significantly. This inconsistency can make it impossible to predict the specific impact of a data breach on an individual. Victims of domestic violence, for example, may be at increased risk when personal information is exposed, creating harms that are difficult to foresee or mitigate. <h2>Enforcing the rules</h2> Interviewees also had concerns about how well the regulator could provide guidance and enforce data protection measures. Many expressed a belief the OAIC is underfunded and lacks the authority to impose and enforce fines properly. The consensus was that the challenge of protecting our data has now outgrown the power and resources of the regulator. As one chief information security officer at a publicly listed company put it: <blockquote> What’s the point of having speeding signs and cameras if you don’t give anyone a ticket? </blockquote> A lack of enforcement can undermine the incentive for organisations to invest in robust data protection. <h2>Only the tip of the iceberg</h2> Data breaches are also underreported, particularly in the corporate sector. One senior cybersecurity consultant from a major multinational company told us there is a strong incentive for companies to minimise or cover up breaches, to avoid embarrassment. This culture means many breaches that should be reported simply aren’t. One senior public servant estimated only about 10% of reportable breaches end up actually being disclosed. Without this basic transparency, the regulator and affected individuals can’t take necessary steps to protect themselves. <h2>Third-party breaches</h2> Sometimes, when we give our personal information to one organisation, it can end up in the hands of another one we might not expect. This is because key tasks – especially managing databases – are often outsourced to third parties. Outsourcing tasks might be a more efficient option for an organisation, but it can make protecting personal data even more complicated. Interviewees told us breaches were more likely when engaging third-party providers, because it limited the control they had over security measures. Between July and December 2023 in Australia, there was an increase of <a href="https://www.oaic.gov.au/privacy/notifiable-data-breaches/notifiable-data-breaches-publications/notifiable-data-breaches-report-july-to-december-2023">more than 300%</a> in third-party data breaches compared to the six months prior. There have been some highly publicised examples. In May this year, many Clubs NSW customers had their personal information potentially <a href="https://www.rimpa.com.au/resource/more-than-a-million-australian-data-records-potentially-exposed-in-nsw-club-and-pub-data-breach.html#:%7E:text=Outabox%2C%20the%20IT%20services%20provider,and%20has%20notified%20law%20enforcement">breached</a> through an attack on third-party software provider Outabox. Bunnings suffered a <a href="https://australiancybersecuritymagazine.com.au/bunnings-customer-data-compromised/">similar breach</a> in late 2021, via an attack on scheduling software provider FlexBooker. <h2>Getting the basics right</h2> Some organisations are still struggling with the basics. Our research found many data breaches occur because outdated or “legacy” data systems are still in use. These systems are old or inactive databases, often containing huge amounts of personal information about all the individuals who’ve previously interacted with them. Organisations tend to hold onto personal data longer than is legally required. This can come down to confusion about data-retention requirements, but also the high cost and complexity of safely decommissioning old systems. One chief privacy officer of a large financial services institution told us: <blockquote> In an organisation like ours where we have over 2,000 legacy systems […] the systems don’t speak to each other. They don’t come with big red delete buttons. </blockquote> Other interviewees flagged that risky data testing practices are widespread. Software developers and tech teams often use “production data” – real customer data – to test new products. This is often quicker and cheaper than creating test datasets. However, this practice exposes real customer information to insecure testing environments, making it more vulnerable. A senior cybersecurity specialist told us: <blockquote> I’ve seen it so much in every industry […] It’s literally live, real information going into systems that are not live and real and have low security. </blockquote> <h2>What needs to be done?</h2> Drawing insights from professionals at the coalface, our study highlights just how complex data protection has become in Australia, and how quickly the landscape is evolving. Addressing these issues will require a multi-pronged approach, including clearer legislative guidelines, better enforcement, greater transparency and robust security practices for the use of third-party providers. As the digital world continues to evolve, so too must our strategies for protecting ourselves and our data.<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/236681/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/jane-andrew-10314">Jane Andrew</a>, Professor, Head of the Discipline of Accounting, Governance and Regulation, University of Sydney Business School, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/dr-penelope-bowyer-pont-1550191">Dr Penelope Bowyer-Pont</a>, Researcher, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>, and <a href="https://theconversation.com/profiles/max-baker-25553">Max Baker</a>, Associate professor, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

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

<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.

Why do I have hay fever? I didn’t have it as a child

<a href="https://theconversation.com/profiles/janet-davies-103598">Janet Davies</a>, <a href="https://theconversation.com/institutions/queensland-university-of-technology-847">Queensland University of Technology</a> and <a href="https://theconversation.com/profiles/joy-lee-1480523">Joy Lee</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> Hay fever (or allergic rhinitis) is a long-term inflammatory condition that’s incredibly common. It affects about <a href="https://www.abs.gov.au/statistics/health/health-conditions-and-risks/national-health-survey-state-and-territory-findings/latest-release">one-quarter</a> of Australians. Symptoms vary but <a href="https://www.allergy.org.au/patients/fast-facts/hay-fever-allergic-rhinitis">can include</a> sneezing, itchy eyes and a runny or blocked nose. Hay fever can also contribute to sinus and ear infections, snoring, poor sleep and asthma, as well as lower performance at school or work. But many people didn’t have hay fever as a child, and only develop symptoms as a teenager or adult. Here’s how a combination of genetics, hormones and the environment can lead to people developing hay fever later in life. <h2>Remind me, what is hay fever?</h2> Hay fever is caused by the nose, eyes and throat coming into contact with a substance to which a person is allergic, known as an allergen. Common sources of outside allergens include airborne grass, weed or tree pollen, and mould spores. Pollen allergens can be carried indoors on clothes, and through open windows and doors. Depending on where you live, you may be exposed to a range of pollen types across the pollen season, but grass pollen is the most common trigger of hay fever. In <a href="https://www.sciencedirect.com/science/article/abs/pii/S0013935122010891?via%3Dihub">some regions</a> the grass pollen season can extend from spring well into summer and autumn. <h2>How does hay fever start?</h2> Hay fever symptoms most commonly start in adolescence or young adulthood. <a href="http://dx.doi.org/10.2147/JAA.S170285">One study</a> found 7% of children aged six had hay fever, but that grew to 44% of adults aged 24. Before anyone has hay fever symptoms, their immune system has already been “sensitised” to specific allergens, often allergens of grass pollen. Exposure to these allergens means their immune system has made a particular type of antibody (known as IgE) against them. During repeated or prolonged exposure to an allergen source such as pollen, a person’s immune system may start to respond to another part of the same allergen, or another allergen within the pollen. Over time, these new allergic sensitisations can lead to development of <a href="https://www.jacionline.org/article/S0091-6749(12)00959-1/fulltext">hay fever</a> and possibly other conditions, such as allergic asthma. <h2>Why do some people only develop hay fever as an adult?</h2> 1. Environmental factors Some people develop hay fever as an adult simply because they’ve had more time to become sensitised to specific allergens. Migration or moving to a new location can also change someone’s risk of developing hay fever. This may be due to exposure to different <a href="https://www.sciencedirect.com/science/article/abs/pii/S0048969722076884">pollens</a>, <a href="https://www.sciencedirect.com/science/article/pii/S0048969724060194?via%3Dihub">climate and weather</a>, green space <a href="https://onlinelibrary.wiley.com/doi/epdf/10.1111/all.14177">and/or</a> air quality factors. A number of studies <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0105347">show</a> people who have migrated from low- and middle-income countries to higher-income countries may be at a higher risk of developing hay fever. This may due to local environmental conditions influencing expression of genes that regulate the immune system. 2. Hormonal factors <a href="http://dx.doi.org/10.1016/j.anai.2015.04.019">Hormonal changes</a> at puberty may also help drive the onset of hay fever. This may relate to sex hormones, such as oestrogen and progesterone, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9392967/#R55">affecting</a> histamine levels, immune regulation, and the response of cells in the lining of the nose and lower airways. 3. Genetic factors <a href="https://www.nature.com/articles/ng.3985">Our genes</a> underpin <a href="https://www.ncbi.nlm.nih.gov/books/NBK542187/">our risk</a> of hay fever, and whether this and other related allergic disease persists. For instance, babies with the skin condition eczema (known as atopic dermatitis) have a <a href="https://www.annallergy.org/article/S1081-1206(21)00172-1/abstract">three times greater risk</a> of developing hay fever (and asthma) later in life. Having a food allergy in childhood is also a risk factor for developing hay fever later in life. In the case of a peanut allergy, that risk is more than <a href="https://pubmed.ncbi.nlm.nih.gov/27542726/">2.5 times greater</a>. <h2>What are the best options for treatment?</h2> Depending on where you live, avoiding allergen exposures can be difficult. But <a href="https://auspollen.edu.au/auspollensitesmap/">pollen count forecasts</a>, if available, can be useful. These can help you decide whether it’s best to stay inside to reduce your pollen exposure, or to take preventative medications. You may also find <a href="https://www.health.vic.gov.au/environmental-health/epidemic-thunderstorm-asthma-risk-forecast">alerts on thunderstorm asthma</a>, where pollens combine with specific weather conditions to trigger <a href="https://theconversation.com/we-could-see-thunderstorm-asthma-in-south-eastern-australia-this-season-heres-how-to-prepare-215793">breathing difficulties</a>. If you have mild, occasional hay fever symptoms, you can take non-drowsy antihistamines, which you can buy at the pharmacy. However, for more severe or persistent symptoms, intranasal steroid sprays, or an intranasal spray containing a steroid with antihistamine, are the <a href="https://theconversation.com/can-i-take-antihistamines-everyday-more-than-the-recommended-dose-what-if-im-pregnant-heres-what-the-research-says-228390">most effective treatments</a>. However, it is important to use these <a href="https://allergyfacts.org.au/allergic-rhinitis-treatment/">regularly and correctly</a>. Allergen immunotherapy, also known as desensitisation, is an <a href="https://onlinelibrary.wiley.com/doi/10.1111/all.13201">effective treatment</a> for people with severe hay fever symptoms that can reduce the need for medication and avoiding allergens. However, it involves a longer treatment course (about three years), usually with the supervision of an allergy or immunology specialist. <h2>When should people see their doctor?</h2> It is important to treat hay fever, because symptoms can significantly affect a <a href="https://bmjopen.bmj.com/content/10/11/e038870.long">person’s quality of life</a>. A GP can: <ul> <li> recommend treatments for hay fever and can guide you to use them correctly </li> <li> organise blood tests to confirm which allergen sensitisations (if any) are present, and whether these correlate with your symptoms </li> <li> screen for asthma, which commonly exists with hay fever, and may require other treatments </li> <li> arrange referrals to allergy or immunology specialists, if needed, for other tests, such as allergen skin prick testing, or to consider <a href="https://www.allergy.org.au/patients/allergy-treatments/allergen-immunotherapy">allergen immunotherapy</a> if symptoms are severe. </li> </ul> <hr /> More information about hay fever is available from the <a href="https://www.allergy.org.au/patients/fast-facts/hay-fever-allergic-rhinitis">Australasian Society of Clinical Immunology and Allergy</a> and <a href="https://allergyfacts.org.au/">Allergy & Anaphylaxis Australia</a>.<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/239409/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/janet-davies-103598">Janet Davies</a>, Respiratory Allergy Stream Co-chair, National Allergy Centre of Excellence; Professor and Head, Allergy Research Group, <a href="https://theconversation.com/institutions/queensland-university-of-technology-847">Queensland University of Technology</a> and <a href="https://theconversation.com/profiles/joy-lee-1480523">Joy Lee</a>, Respiratory Allergy Stream member, National Allergy Centre of Excellence; Associate Professor, School of Translational Medicine, <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.

How do heat protectants for hair work? A chemistry expert explains

<a href="https://theconversation.com/profiles/daniel-eldridge-1494633">Daniel Eldridge</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a> Heat can do amazing things to change your hairstyle. Whether you’re using a curling wand to get ringlets, a flat iron to straighten or a hair dryer to style, it’s primarily the heat from these tools that delivers results. This comes with casualties. While your hair is surprisingly tolerant to heat compared with many other parts of your body, it can still only withstand so much. Heat treatment hair appliances frequently operate at over 150°C, with some reportedly <a href="https://www.frontiersin.org/journals/bioengineering-and-biotechnology/articles/10.3389/fbioe.2019.00298/full#B13">reaching</a> <a href="https://www.researchgate.net/publication/289291195_Thermal_degradation_of_hair_I_Effect_of_curling_irons">over 200°C</a>. At these temperatures, your hair can end up fried. Many people use heat protectants, often in the form of sprays, to minimise the damage. So how do these protectants work? To answer that, I first have to explain exactly what heat does to your tresses on the molecular level. <h2>What heat does to your hair</h2> A large proportion of your hair is made up of proteins. There are attractive forces between these proteins, known as hydrogen bonds. These bonds play a big role in dictating the shape of your locks. When you heat up your hair, the total attraction of these hydrogen bonds become weaker, allowing you to more easily re-shape your hair. Then, when it cools back down, these attractions between the proteins are re-established, helping your hair hold its new look until the proteins rediscover their normal structure. The cuticle – the outermost protective layer of your hair – contains overlapping layers of cells that lose integrity when they’re heated, damaging this outer protective layer. Inside that outer layer is the cortex, which is rich in a protein called keratin. Many proteins don’t <a href="https://pubmed.ncbi.nlm.nih.gov/21635854/">hold up structurally</a> after intense heating. Think of cooking an egg – the change you see is a result of the heat altering the proteins in that egg, unravelling them into different shapes and sizes. It’s a <a href="https://library.scconline.org/v049n04/33">similar story</a> when it comes to heating your hair. The proteins in your hair are also susceptible to heat damage, reducing the overall strength and integrity of the hair. Heat can also affect substances called melanin and <a href="https://pubmed.ncbi.nlm.nih.gov/21443842/">tryptophan</a> in your hair, resulting in a change in pigmentation. Heat-damaged hair is <a href="https://pubmed.ncbi.nlm.nih.gov/21635854/">harder to brush</a>. The damage is even more devastating if you use heat styling tools such as <a href="https://labmuffin.com/why-you-should-never-straighten-or-curl-wet-hair/">curling irons or straighteners</a> to <a href="https://library.scconline.org/v062n01/23">heat wet hair</a>, as at the high treatment temperatures, the water soaked up by the fibres can violently evaporate. The result of this is succinctly described by science educator and cosmetic chemist Michelle Wong, also known as <a href="https://labmuffin.com/how-do-heat-protectant-hair-products-work/">Lab Muffin</a>. She notes if you heat wet hair this way, “steam will blast through your hair’s structure”. This steam bubbling or bursting through the hair can <a href="https://pubmed.ncbi.nlm.nih.gov/21443842/">cause substantial damage</a>. It’s worth noting hair dryers don’t concentrate heat in the same way as styling tools such as flat irons or curling wands, but you still need to move the hair dryer around constantly to avoid heat building up in one spot and causing damage. Once heat damage is done, regardless of whether it is severe or mild, the best remaining options are symptom management or a haircut. For all of these reasons, when you’re planning to heat treat your hair, protection is a good idea. <h2>How hair protectants work</h2> When you spray on a hair protectant, many possible key ingredients can go to work. They can have <a href="https://library.scconline.org/v062n01/15">daunting-looking names</a> like polyvinyl pyrrolidone, methacrylates, polyquaterniums, silicones and more. These materials are chosen because they readily stick onto your hair, creating a coating, a bit like this: <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?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/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=225&fit=crop&dpr=1 600w, https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=225&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=225&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=283&fit=crop&dpr=1 754w, https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=283&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=283&fit=crop&dpr=3 2262w" alt="A cartoon of coating attached to a strand of hair." /></a><figcaption>Hair protectant applies a coating to your hair.

Author provided</figcaption></figure> <a href="https://library.scconline.org/v049n04/33">This helps</a> prevent moisture loss and damage to both the protective surface cell layer (the cuticle) and the protein structure of the hair cortex. For these barriers to work at their best, these heat-protecting layers need to remain bound to your hair. In other words, they stick on really well. For this reason, continued use can sometimes cause a <a href="https://link.springer.com/article/10.1007/s12221-010-0507-9">buildup</a> which can change the feel and weight of your hair. This buildup is not permanent and can be removed with washing. One final and important note: just like when you use a mitt for the oven, heat does still get through. The only way to prevent heat damage to your hair altogether is to not use heated styling tools.<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/233206/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/daniel-eldridge-1494633">Daniel Eldridge</a>, Senior Lecturer in Chemistry, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

10 things you should never do on a cruise balcony

While many cruise ship passengers may think they can abide by their own rules in the comfort of their cabins, there are still many cruise ship etiquette rules to follow. Even though some passengers may have private balconies in their rooms, that doesn't mean you can act as if no one is watching. It's important to follow these rules while in your rooms and on your balcony to ensure you'll never be forced to cop the consequences of bad behaviour. 1. Smoke Smoking on cruise balconies is a real no-no. Not only is the wafting smoke an unpleasant smell, but a half-burning cigarette blown back aboard can potentially be a fire hazard. 2. Make too much noise One think that’s often forgotten is the fact that when we’re standing on our cruise ship balconies we’re well within earshot of our neighbours, so keep the volume down. 3. Go nude The thing people sun bathing in one their cruise ship balcony in their birthday suit don’t realise is many balconies are tiered, so you may actually be in view of others. 4. Stand or climb on railings Now this should be obvious, but you should never stand on the railings or the verandah furniture can significantly increase your risk of being thrown overboard. 5. Throw items overboard It might be tempting to toss a message in a beer bottle overseas, but there are strict regulations. Not only is this dangerous, it’s also not environmentally friendly. 6. Dry clothes It can be quite difficult to dry your swimmers when you’re off a cruise, but one strong gust of wind could mean you could go the rest of your cruise without bathers. 7. Leave the balcony door open On a hot and humid day, leaving the balcony door ajar might seem like a good idea, but the gusty sea breeze can wreak havoc with any loose items in your cabin. 8. Light a candle It might seem like it’s a good way to enhance the mood, but any open flame on a cruise ship is a fire hazard, and lighting a candle is almost always against regulations. 9. Leave the balcony light on If your cruise balcony has outdoor lighting, make sure you turn if off when you’re not actually using it, to save electricity and not disturb your neighbours. 10. Amorous behaviour Cruises are inherently romantic holidays, but you might need to avoid overt displays of affection. As mentioned above, balconies are not be as private as you think.

How to keep doing good once you’re gone

Most of us like to think that once we are no longer walking the Earth, we can still leave a legacy to mark our time here and contribute positively to those left behind. Doing so is not only possible but, as you’ll see below, fairly straightforward – providing you do some basic preparation beforehand. Seek the help of professional advice to ensure your plans can be enacted in full and deliver the best possible outcomes for everyone involved. Have your affairs in order Make things simpler for your grieving loved ones by having your wishes clearly outlined in writing, with specific instructions that leave no room for misinterpretation. Doing so makes your wishes easier to implement, faster to enact and reduces fights among your beneficiaries. Keep your will and other affairs updated as circumstances change too, so that everyone you want is included (such as kids and grandkids) and those you don’t, aren’t given an unexpected windfall (such as your ex or an adult child’s ex). Provide for everyone Providing for everyone is not necessarily straight forward, especially if you have a blended family. For instance, leaving your share of your home to your children from a previous relationship could lead to disagreements if your partner doesn’t want to leave. Instead, think about how your assets can be divided fairly without disadvantaging anyone. Children could be nominated beneficiaries of your superannuation and/or life insurance, leaving your home for your partner. Keep wealth flowing Certain structures can allow you to keep giving to your descendants long after you’re gone – offsetting their income and providing far greater wealth over time than any lump sum could achieve. A family or testamentary trust allows ongoing wealth creation through shared assets, with regular dividends paid out, creating a family legacy that can last for generations. Or a family company can allow a commercial entity to continue trading and growing as an asset. Manage tax impacts Implement tax-effective strategies that maximise how much your beneficiaries actually receive and minimise what the tax man pockets. While there isn’t an inheritance tax per se, beneficiaries can be hit with Capital Gains Tax (CGT) on asset sales plus transfer costs to put an asset into their own name – not to mention the ongoing maintenance and compliance costs of asset ownership. In some instances, your loved ones may benefit more if you sell assets now and leave them the proceeds, rather than leave them the asset – and its associated tax bill – once you’re gone. Ensure loved ones are home and housed Property is perhaps the biggest of all sources of wealth, yet it is increasingly difficult for younger people and singles to get (and stay) on the property ladder. Ensure everyone can reap the benefits of property ownership over their own lifetime, either by transferring ownership of properties in your name or contributing chunks of cash towards a deposit. However, it’s important to do so sustainably – gifting grandkids a large property they can’t afford to maintain isn’t going to work. Charitable donations Many people like to support charities and social causes once they are gone. Consider the end user here and what they stand to benefit from your donation – whether it be people, planet or both. It could be leaving a lump sum on your death, or regular ongoing donations from your estate. You may wish to do so anonymously, or include a message with your donation outlining your reasons why that particular charity/cause is important to you and what you hope the money will go towards. Donations may not necessarily be financial either – perhaps you have a valuable historic artefact that others could enjoy if donated to a museum? Organ donation The greatest gift of all is not money but life itself. So, consider whether organ donation is something you wish to do. While not suitable for everyone, and dependent on a range of factors including your age, health and religious beliefs, a single organ donor can save up to seven lives, as well as improve the quality of life of numerous others through eye and tissue donation. That is a lot of life you can give to others – and all without costing your own loved ones a cent!

How do I know when it’s time to replace my running shoes?

<a href="https://theconversation.com/profiles/john-arnold-178470">John Arnold</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> and <a href="https://theconversation.com/profiles/joel-fuller-2210202">Joel Fuller</a>, <a href="https://theconversation.com/institutions/macquarie-university-1174">Macquarie University</a> Any runner will tell you there’s nothing better than slipping on a brand new pair of shoes. But how regularly should runners fork out hundreds of dollars on their next pair? Conventional wisdom tells us the average lifespan of a running shoe is around 500 to 800 kilometres. But where did this advice come from, and is it based on science? Some evidence comes from <a href="https://doi.org/10.1177/0363546585013004">impact testing</a> with machines designed to simulate the shoe repeatedly contacting the ground during running. Other evidence comes from <a href="https://doi.org/10.1080/19424280.2010.519348">monitoring runners who have used shoes in the real world</a> for long periods. This research is often focused on shoe materials and structure. But we think more compelling markers for the runner are shoe comfort, performance benefit and injury risk. Rather than seeking a “one-size-fits-all” answer to how many kilometres your shoes should be limited to, it’s also better to consider individual signs based on your shoe type and its purpose. <h2>The three signs to watch for</h2> Runners tend to replace their shoes for three main reasons: <ol> <li>they believe their performance is being negatively impacted</li> <li>their shoes are leading to some bodily discomfort which may cause (or has already caused) an injury</li> <li>the shoes are no longer comfortable or “feel” as good as they used to.</li> </ol> So what does the evidence say about these factors? <h2>Performance</h2> Some shoe material properties do contribute to enhanced running efficiency. Degrading these materials by racking up the kilometres may hinder peak performance on race day. This is most clearly seen in carbon fibre plate shoes used by modern elite runners to achieve <a href="https://doi.org/10.1007/s40279-020-01420-7">rapid road race times</a>. The design features <a href="https://doi.org/10.1007/s40279-018-1024-z">thought to drive this</a> are the combination of highly compliant and resilient midsole foam and a stiff embedded carbon fibre plate, which support energy storage and return. Runners will typically “save” these shoes for race day and replace them after fewer kilometres, compared to conventional running shoes. The available research does support the <a href="https://doi.org/10.1007/s40279-017-0811-2">performance benefits of these shoes</a>. However, it’s not known how long the benefits last relative to kilometres of wear. To our best knowledge, there’s only one study on running performance and shoe wear, but unfortunately it did not involve carbon fibre plate shoes. A University of Connecticut 2020 <a href="http://hdl.handle.net/11134/20002:860659513">master’s thesis</a> investigated eight college-level runners over 400 miles (643km) of Nike Pegasus shoe use. Large reductions in running economy were reported at 240km, and this was statistically significant at 320km. No reduction was observed at 160km. So, if you’re chasing personal best times, the evidence above suggests that for peak performance, shoes should be replaced somewhere between 160 and 240km (although this is not directly based on carbon fibre plate shoe research). It appears that minimising training kilometres for your favourite racing shoes – keeping them “fresh” – could contribute to peak performance on race day, compared to racing in a pair of old shoes. <h2>Injury or discomfort</h2> The link between shoe wear and injury is unclear, and based on <a href="https://bjsm.bmj.com/content/37/3/239">minimal and often conflicting evidence</a>. One study did find that <a href="https://doi.org/10.1111/sms.12154">runners who alternate their running shoes</a> have a lower risk of injury than runners who run only in the same pair of shoes over a 22-week period. Runners who alternated shoes throughout the study period would have accumulated less wear in each shoe. This provides some support for the notion that accumulating too many kilometres in your shoes may increase risk of injury. Unfortunately, the exact age of running shoes was not reported in this study. However, based on the running characteristics reported, the single-shoe pair users completed an average of 320km in their shoes (after adjusting for a small fraction who had to replace shoes during the study). This was compared to the multi-shoe pair users who used an average of 3.6 pairs of shoes, ran more total kilometres, but accumulated an average of only 200km per shoe pair. <h2>Comfort</h2> Comfort and fit are the <a href="https://www.tandfonline.com/doi/full/10.1080/19424280.2024.2353597#abstract">two most important factors</a> to runners when selecting running shoes. Evidence linking improved shoe comfort to <a href="https://journals.lww.com/acsm-msse/fulltext/2001/11000/relationship_between_footwear_comfort_of_shoe.21.aspx">reduced injury rates</a> or <a href="https://www.tandfonline.com/doi/full/10.1080/17461391.2019.1640288">improved running economy</a> is mixed, but reducing harms from poorly fitting and uncomfortable shoes is clearly a priority for runners. Most <a href="https://commons.nmu.edu/isbs/vol35/iss1/293/">runners land on their heel</a>. The repeated compression of the midsole causes the material to harden, possibly after as <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5534152/pdf/ijspt-12-616.pdf">little as 160km</a>, according to one study from 2017. However, there was virtually no change in the amount of cushioning runners perceived under their heel after 160km. Even after using the shoes for 640km, they felt little difference – about 3%. While at first this might seem like runners are not very good at judging when shoes lose their cushioning, it also tells us changes in perceived shoe cushioning are very gradual and may not be important for runners until they reach a certain threshold. This amount will differ from person to person, and from shoe to shoe, but research suggests it’s not until perceived cushioning reaches about a <a href="https://www.tandfonline.com/doi/full/10.1080/02640414.2020.1773613?casa_token=P87vatZhOlgAAAAA%3ACu11TZmGjKc1xYsaUlEVfWvZDvcSnx3qgKL1E2DsRYwf6hMvBiyVAm-M_-4Iauq4lwHna0QMu1IRmw">10% change</a> that runners consider it meaningful. We must be careful when applying these findings to the latest running shoes which use newer materials. But you can use it as a rule of thumb – once you notice a drop in comfort, it’s time to get a new pair. <h2>When to choose new shoes</h2> Ultimately, there’s no one simple answer for when you should get new running shoes. You may also not keep close track of how many kilometres your favourite pair has racked up. Overall, we believe the most practical advice is to keep your racing shoes “fresh” (under 240km), alternate a couple of other pairs during regular training, and replace them when you detect a notable drop in comfort.<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/238997/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/john-arnold-178470">John Arnold</a>, Senior lecturer, Sport & Exercise Biomechanics, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> and <a href="https://theconversation.com/profiles/joel-fuller-2210202">Joel Fuller</a>, Senior Lecturer, Department of Health Sciences, <a href="https://theconversation.com/institutions/macquarie-university-1174">Macquarie University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Kate Middleton helps teen with cancer fulfill "bucket list" dream

Kate Middleton has taken another step back to public duties after inviting a teenage girl with a rare form of cancer to Windsor Castle. The Prince and Princess of Wales invited 16-year-old Liz, a budding photographer from Harrogate, North Yorkshire, to Windsor Castle after the teen was told by doctors earlier this year that she only had between six months and three years to live. “A pleasure to meet with Liz at Windsor today,” the Prince and Princess of Wales wrote in a social media post shared on Wednesday, with a photo of Kate hugging the teenager. “A talented young photographer whose creativity and strength has inspired us both. Thank you for sharing your photos and story with us.” <blockquote class="instagram-media" style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" data-instgrm-captioned="" data-instgrm-permalink="https://www.instagram.com/p/DAoPPEMNX6F/?utm_source=ig_embed&utm_campaign=loading" data-instgrm-version="14"> <div style="padding: 16px;"> <div style="display: flex; flex-direction: row; align-items: center;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;"> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;"> </div> </div> </div> <div style="padding: 19% 0;"> </div> <div style="display: block; height: 50px; margin: 0 auto 12px; width: 50px;"> </div> <div style="padding-top: 8px;"> <div style="color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;">View this post on Instagram</div> </div> <div style="padding: 12.5% 0;"> </div> <div style="display: flex; flex-direction: row; margin-bottom: 14px; align-items: center;"> <div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(0px) translateY(7px);"> </div> <div style="background-color: #f4f4f4; height: 12.5px; transform: rotate(-45deg) translateX(3px) translateY(1px); width: 12.5px; flex-grow: 0; margin-right: 14px; margin-left: 2px;"> </div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(9px) translateY(-18px);"> </div> </div> <div style="margin-left: 8px;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 20px; width: 20px;"> </div> <div style="width: 0; height: 0; border-top: 2px solid transparent; border-left: 6px solid #f4f4f4; border-bottom: 2px solid transparent; transform: translateX(16px) translateY(-4px) rotate(30deg);"> </div> </div> <div style="margin-left: auto;"> <div style="width: 0px; border-top: 8px solid #F4F4F4; border-right: 8px solid transparent; transform: translateY(16px);"> </div> <div style="background-color: #f4f4f4; flex-grow: 0; height: 12px; width: 16px; transform: translateY(-4px);"> </div> <div style="width: 0; height: 0; border-top: 8px solid #F4F4F4; border-left: 8px solid transparent; transform: translateY(-4px) translateX(8px);"> </div> </div> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center; margin-bottom: 24px;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 224px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 144px;"> </div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" href="https://www.instagram.com/p/DAoPPEMNX6F/?utm_source=ig_embed&utm_campaign=loading" target="_blank" rel="noopener">A post shared by The Prince and Princess of Wales (@princeandprincessofwales)</a> </div> </blockquote> Liz had a photography bucket list "to create a lifetime of memories" after being diagnosed with desmoplastic small round cell tumour in January. The cancer has no form of standard treatment. She first took up photography in Year 6 after saving up to buy her first camera. Liz was given the opportunity to take photos of cyclist Mark Cavendish and ex-footballer Ally McCoist's investiture ceremony, after Prince William heard about her through his patronage of London Air Ambulance Charity. A Kensington Palace spokesperson said: “Following the investiture both the Prince and Princess of Wales met Liz privately with her family to hear about her day and journey." Liz said she was "over the moon" after meeting the couple at the castle. “Such lovely, genuine and kind people, I’m over the moon that my family and I had this experience,” she recalled on social media. The event is a rare appearance for the Princess who has been out of the public eye for most of the year following her own cancer diagnosis earlier this year. While the meeting is not being treated as an official engagement for the Prince and Princess, it was their first joint appearance this year. Images: Instagram

Why are we seeing more pandemics? Our impact on the planet has a lot to do with it

<a href="https://theconversation.com/profiles/olga-anikeeva-1522907">Olga Anikeeva</a>, <a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a>; <a href="https://theconversation.com/profiles/jessica-stanhope-1129888">Jessica Stanhope</a>, <a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a>; <a href="https://theconversation.com/profiles/peng-bi-1522908">Peng Bi</a>, <a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a>, and <a href="https://theconversation.com/profiles/philip-weinstein-882901">Philip Weinstein</a>, <a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a> Pandemics – the global spread of infectious diseases – seem to be making a comeback. In the Middle Ages we had the Black Death (plague), and after the first world war we had the Spanish flu. Tens of millions of people <a href="https://assets.cureus.com/uploads/review_article/pdf/69273/20211019-25919-an4y6h.pdf">died from these diseases</a>. Then science began to <a href="https://www.frontiersin.org/journals/immunology/articles/10.3389/fimmu.2011.00053/full">get the upper hand</a>, with vaccination eradicating smallpox, and polio nearly so. Antibiotics became available to treat bacterial infections, and more recently antivirals as well. But in recent years and decades pandemics <a href="https://assets.cureus.com/uploads/review_article/pdf/69273/20211019-25919-an4y6h.pdf">seem to be returning</a>. In the 1980s we had HIV/AIDS, then several flu pandemics, SARS, and now COVID (no, COVID isn’t over). So why is this happening, and is there anything we can do to avert future pandemics? <h2>Unbalanced ecosystems</h2> Healthy, stable ecosystems provide services that keep us healthy, such as supplying food and clean water, producing oxygen, and making green spaces available for our <a href="https://www.millenniumassessment.org/documents/document.356.aspx.pdf">recreation and wellbeing</a>. Another key service ecosystems provide is disease regulation. When nature is in balance – with predators controlling herbivore populations, and herbivores controlling plant growth – it’s more difficult for pathogens to emerge in a way that causes pandemics. But when human activities <a href="https://books.google.com.au/books?hl=en&lr=&id=rWozz12K1aUC&oi=fnd&pg=PP15&dq=planetary+overload&ots=c9mWuESUXN&sig=-1iP3uSOWazvC2OFLk4vginWbQQ&redir_esc=y#v=onepage&q=planetary%20overload&f=false">disrupt and unbalance ecosystems</a> – such as by way of climate change and biodiversity loss – <a href="https://academic.oup.com/bioscience/article/58/8/756/381265">things go wrong</a>. For example, climate change affects the number and distribution of plants and animals. Mosquitoes that carry diseases can move from the tropics into what used to be temperate climates as the planet warms, and may infect more people in the months that are normally disease free. We’ve studied the relationship between weather and dengue fever transmission in China, and <a href="https://pubmed.ncbi.nlm.nih.gov/27883970/">our findings</a> support the same conclusion reached by <a href="https://journals.plos.org/plosntds/article?id=10.1371/journal.pntd.0008118">many other studies</a>: climate change is likely to put more people at risk of dengue. Biodiversity loss can have similar effects by disrupting food chains. When ranchers cleared forests in <a href="https://www.mdpi.com/1999-4915/6/5/1911">South America</a> for their cattle to graze in the first half of the 20th century, tiny forest-dwelling, blood-feeding vampire bats suddenly had a smörgåsbord of large sedentary animals to feed on. While vampire bats had previously been kept in check by the limited availability of food and the presence of predators in the balanced <a href="https://cir.nii.ac.jp/crid/1130000797648461952">forest ecosystem</a>, numbers of this species exploded in South America. These bats carry the rabies virus, which causes <a href="https://www.who.int/news-room/fact-sheets/detail/rabies">lethal brain infections</a> in people who are bitten. Although the number of deaths from bat-borne rabies has now fallen dramatically due to vaccination programs in South America, rabies caused by bites from other animals still <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3168224/">poses a global threat</a>. As urban and agricultural development impinges on natural ecosystems, there are increasing opportunities for humans and domestic animals to become infected with pathogens that would normally only be seen in wildlife – particularly when people hunt and eat animals from the wild. The HIV virus, for example, <a href="https://www.tandfonline.com/doi/abs/10.1076/jmep.27.2.163.2992">first entered human populations</a> from apes that were slaughtered for food in Africa, and then spread globally through travel and trade. Meanwhile, bats are thought to be <a href="https://www.sciencedirect.com/science/article/pii/S0006291X20319434">the original reservoir</a> for the virus that caused the COVID pandemic, which has killed more than <a href="https://www.worldometers.info/coronavirus/">7 million people</a> to date. Ultimately, until we effectively address the unsustainable impact we are having on our planet, pandemics will continue to occur. <h2>Targeting the ultimate causes</h2> Factors such as climate change, biodiversity loss and other global challenges are the ultimate (high level) cause of pandemics. Meanwhile, increased contact between humans, domestic animals and wildlife is the proximate (immediate) cause. In the case of HIV, while direct contact with the infected blood of apes was the proximate cause, the apes were only being slaughtered because large numbers of very poor people were hungry – an ultimate cause. The distinction between <a href="https://link.springer.com/article/10.1007/BF02207379">ultimate causes and proximate causes</a> is important, because we often deal only with proximate causes. For example, people may smoke because of stress or social pressure (ultimate causes of getting lung cancer), but it’s the toxins in the smoke that cause cancer (proximate cause). Generally, health services are only concerned with stopping people from smoking – and with treating the illness that results – not with removing the drivers that lead them to smoke in the first place. Similarly, we address pandemics with lockdowns, mask wearing, social distancing and vaccinations – all measures which seek to stop the spread of the virus. But we pay less attention to addressing the ultimate causes of pandemics – until perhaps very recently. <h2>A planetary health approach</h2> There’s a growing awareness of the importance of adopting a “planetary health” approach to improve human health. This <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(15)60901-1/fulltext?nr_email_referer=1">concept</a> is based on the understanding that human health and human civilisation depend on flourishing natural systems, and the wise stewardship of those natural systems. With this approach, ultimate drivers like climate change and biodiversity loss would be prioritised in preventing future pandemics, at the same time as working with experts from many different disciplines to deal with the proximate causes, thereby reducing the risk overall. The planetary health approach has the benefit of improving both the health of the environment and human health concurrently. We are heartened by the increased uptake of teaching planetary health concepts across the environmental sciences, humanities and health sciences in many universities. As climate change, biodiversity loss, population displacements, travel and trade continue to increase the risk of disease outbreaks, it’s vital that the planetary stewards of the future have a better understanding of how to tackle the ultimate causes that drive pandemics.

Readers response: What do you regret not appreciating more when you were younger?

When it comes to ageing, we often learn to appreciate things that we often dismissed when we were younger. We asked our readers what they have only truly started to appreciate with age, and the response was overwhelming. Here's what they said. Ross Forbes - Being brought up on a farm in a family environment where I was taught excellent work ethics and the value of community. Alice McMurdo - The beauty of the scenery in Scotland and not taking the opportunity to see more of the beautiful countryside when I had the chance. Pat Isaacs - My health and energy. Esther Miller - Not having to pay bills. I now understand why my daddy was always telling us cut off the light, shut the door, stop wasting food, do not pour more milk than you are going to drink. I remember him saying "wait till you have to pay for it yourselves". Lesson learned. Marie Chong - My parents. Rosalie Jones - Movement without pain. Michelle Nightingale - My family. Sally O'Neill - Being happy and free, not having any responsibilities to worry about. Chris Gray - My mum. If only I had known what I now know. Margie Buckingham - My ability to always be employed and buy my first house at 21. Also, my upbringing and great start my parents gave me by ensuring I went to a good school and studied hard.
