Why you should revisit the classics, even if you were turned off them at school

<p><em><a href="https://theconversation.com/profiles/johanna-harris-305384">Johanna Harris</a>, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a></em></p> <p>Throughout my school years I had an exuberant, elderly piano teacher, Miss Hazel. She was one of five daughters (like me) and, like many young women of her generation, had never married her sweetheart because he did not return from the war.</p> <p>Her unabashed gusto for life and infectious, positive outlook left an indelible impression upon me. So too did the memorable fact that Miss Hazel read Jane Austen’s <a href="https://www.goodreads.com/book/show/84979.Pride_and_Prejudice">Pride and Prejudice</a> from beginning to end once every year.</p> <p>As a younger girl I wondered about the ways Pride and Prejudice could be so important to a woman in her eighties that she would want to read it annually. Was it to do with Austen’s depiction of a family with five daughters, or to relive an endearing love story?</p> <p>Since those years I have seen, more through lived experience than through academic study, just how deeply meaningful the reading of classic books, like Pride and Prejudice, can be.</p> <figure class="align-left zoomable"></figure> <p>I no longer simply read this book for Elizabeth Bennett’s love story, but for the finely crafted replication Austen gives us of human character, with all its flaws. Hers are imaginary yet imaginably real situations, all depicted with humour and a sensitively calibrated dose of sympathy for even the most unlikeable literary figures.</p> <p>The clergyman Mr Collins, Elizabeth’s distant cousin and her rejected suitor, was always repellent for his obsequiousness but I see more readily now his self-serving nature cloaked in altruism. The haughty snobbery of Darcy’s aristocratic aunt, Lady Catherine de Bourgh, hints at a deeper layer of sadness and fragility only rereading can illuminate.</p> <h2>Box-ticking and speed</h2> <p>When we’re at school or university we may read for speed. I remember managing my reading of Ann Radcliffe’s 432-page gothic romance <a href="https://www.goodreads.com/book/show/93135.The_Romance_of_the_Forest?from_search=true&amp;from_srp=true&amp;qid=oU6912stkW&amp;rank=1">The Romance of the Forest</a> to work out how many pages per hour I would need to read across a weekend in order to finish the novel before my university tutorial. (It was an ungodly ratio and I don’t recall much of the novel.)</p> <figure class="align-right zoomable"></figure> <p>Or we may read for the tick-box exercise of writing for assessment requirements: accumulating knowledge of a novel’s original metaphors, descriptions that best capture a prescribed theme (“belonging” or “identity”), or of poetry by which we can demonstrate a grasp of innovative metre.</p> <p>But how and why do we reread classic books, when we are not constrained by class plans or prescribed exam themes. And why should we?</p> <h2>‘Like a graft to a tree’</h2> <p>Rebecca Mead’s <a href="https://www.goodreads.com/book/show/20924311-the-road-to-middlemarch?from_search=true&amp;from_srp=true&amp;qid=Cm2E7fwgeL&amp;rank=1">The Road to Middlemarch</a> offers a compelling exploration of one writer’s five-yearly revisitation of George Eliot’s masterpiece, <a href="https://www.goodreads.com/book/show/19089.Middlemarch?from_search=true&amp;from_srp=true&amp;qid=CRcxE3ftkB&amp;rank=1">Middlemarch</a>.</p> <p>Mead first read the novel at school, and Eliot’s subtitle to the novel, “A Study of Provincial Life”, captured precisely what Mead was trying to escape at that time: provinciality.</p> <p>Eliot’s central character, Dorothea Brooke, captivated Mead as an unconventional intellectual heroine yearning for a life of meaning and significance. Mead marked out important moments with a fluorescent pen, such as when the intellectual and spiritual inadequacies of Dorothea’s husband, <a href="https://www.britannica.com/topic/Edward-Casaubon">Casaubon</a>, dawn upon her. Mead writes, quoting Eliot:</p> <blockquote> <p>‘Now when she looked steadily at her husband’s failure, still more at his possible consciousness of failure, she seemed to be looking along the one track where duty became tenderness […]’ These seemed like things worth holding on to. The book was reading me, as I was reading it.</p> </blockquote> <figure class="align-left zoomable"></figure> <p>This idea of books “reading us” can sound like an odd animism. But books can prompt us to reflect on our own lives, too. Eliot makes Middlemarch almost compulsory to reread later in life: the idealism of youth captures the young reader, while the novel’s humour becomes more sympathetic as we age. To reread a novel like Middlemarch is to trace the ways we too have experienced idealism turn to illusion, or have seen the restless pursuit of change turn to a retrospective gratitude and a recognition of grace.</p> <p>Our ability to acknowledge new depths of meaning in our own lives and to recognise within ourselves a subtler sympathy for the lives of others can be articulated almost as precisely as lived experience itself. As Mead says, “There are books that grow with the reader as the reader grows, like a graft to a tree.”</p> <h2>Feeling for Lear</h2> <p>The same can be said of Shakespeare. As young readers, we won’t necessarily capture the full vision <a href="https://www.goodreads.com/book/show/12938.King_Lear?from_search=true&amp;from_srp=true&amp;qid=nowKY1f5aB&amp;rank=1">King Lear</a> offers us of the tragicomic paradoxes sometimes presented by old age. The play depicts the loss of power and control over one’s life and decision-making, the tender fragility of family relationships when the care of aged parents is suddenly an urgent question and the madness that can prevail when an inheritance is at stake.</p> <figure class="align-right zoomable"></figure> <p>Some of these things might abstractly be understood when taught to us in the classroom, but they are far more powerfully seen when revisited after we have lived a little more of that imaginably real life ourselves.</p> <p>As students we might have squirmed with discomfort at the literal blinding of Lear’s loyal subject the Earl of Gloucester (the horror of witnessing a visceral, grotesque injury).</p> <p>But as we age it is the tragedy of moral blindness that lingers, making the final scene so extraordinarily moving: “Do you see this? Look on her. Look, her lips. Look there, look there,” Lear pleads, as if to say that Cordelia, lifeless in his arms, still breathes.</p> <p>Does he really see her lips quiver? Does he really believe she lives? Is this some consolation with which he dies or is it delusion? Lear’s heart is broken. So is mine.</p> <p>Each time I revisit this final scene, the grief of Lear as a father is profoundly felt, but my heart is broken even more so by his continuing blindness; his vision (what he thinks he sees) is desperate, untrue, and ultimately meaningless.</p> <h2>Sites of discovery</h2> <p>When we read we inhabit imaginary worlds and each time the reading can be different. Philip Davis, a professor of literature and psychology <a href="https://global.oup.com/academic/product/reading-and-the-reader-9780199683185?cc=au&amp;lang=en&amp;">has written</a>,</p> <blockquote> <p>Rereading is important in checking and refreshing that sense of meaning, as the reader goes back and re-enters the precise language once again.</p> </blockquote> <p>Davis points to an idea advanced by the novelist and philosopher Iris Murdoch, of the reader’s collection of special, memorable fragments, which serve as metaphors for the reader’s self-utterances, developed over time. These are “nascent sites for thinking and re-centring”.</p> <p>This is a similar idea to the novelist and journalist Italo Calvino’s description in <a href="https://www.goodreads.com/book/show/9814.Why_Read_the_Classics_?from_search=true&amp;from_srp=true&amp;qid=RALd1Dx5a9&amp;rank=1">Why Read the Classics?</a> of the way classic books “imprint themselves on our imagination as unforgettable” and “hide in the layers of memory disguised as the individual’s or the collective unconscious.”</p> <p>Works of imaginative literature are not manuals for life, though they might along the way gift us with some wisdom; they are sites of discovery and rediscovery.</p> <p>The classic works we are introduced to at school may establish such sites for thinking about ourselves and others, but it is in rereading them as we grow older that we can better see the ways we have grown as imaginative, moral beings.<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/246147/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/johanna-harris-305384">Johanna Harris</a>, Associate Professor, Literature, Western Civilisation Program, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

From sunscreen to essential oils, why some personal care products could be harmful to your health

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/asit-kumar-mishra-1458839">Asit Kumar Mishra</a>, <a href="https://theconversation.com/institutions/university-college-cork-1321">University College Cork</a></em></p> <p>Each time you apply sunscreen to your face, you may inhale somewhere between <a href="https://www.mdpi.com/1660-4601/20/11/5944">10 to 30 milligrams of ethanol</a>, the type of alcohol used in alcoholic drinks. While the ethanol in sunscreen may not give you a buzz, it could make you think about what other chemicals you might be exposed to from personal care products.</p> <p>Products that are applied to the face, like sunscreen, can increase the inhalation of some chemicals by ten times or more than you would inhale from your <a href="https://pubmed.ncbi.nlm.nih.gov/34816489/">home air in the entire day</a>.</p> <p>The levels of ethanol in cosmetics and skincare products may be reasonably safe – although it can still dry out the skin, causing pain, redness and swelling, and <a href="https://www.gov.uk/government/publications/ethanol-properties-uses-and-incident-management/ethanol-general-information">irritate the eyes</a>, causing tears, burning and stinging – but personal care products such as shampoos, skin creams, deodorants, cosmetics and perfumes contain fragrances and other volatile organic compounds (VOCs), which can be inhaled, absorbed through skin or ingested and some are more toxic than others.</p> <p>Unfortunately, manufacturers of personal care products <a href="https://link.springer.com/article/10.1007/s11869-015-0327-6">do not have to disclose</a> every fragrance compound used. This is concerning when you consider the potential effects of toxic compounds that <a href="https://pubmed.ncbi.nlm.nih.gov/34816489/">have been detected</a> in the air from personal care products. For example, hair-smoothing products have released formaldehyde, a toxic chemical that can cause <a href="https://www.ncbi.nlm.nih.gov/books/NBK597627/">a range of symptoms</a> from dermatitis to low sperm count. Some perfumes and deodorants have generated monoterpenes, chemicals which <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC8912113/#sec1-molecules-27-01716">can prove toxic</a> for some users.</p> <figure><iframe src="https://www.youtube.com/embed/cfloNXKeyX8?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>Some of the VOCs found in personal care products <a href="https://pubmed.ncbi.nlm.nih.gov/36976159/">may trigger</a> skin irritation, headaches – and difficulty breathing, which can develop into an asthma attack in some users. The highest or peak concentration of these VOCs are likely to <a href="https://pubmed.ncbi.nlm.nih.gov/22406137/">occur within ten minutes</a> of application. But these concentrations may take up to <a href="https://pubmed.ncbi.nlm.nih.gov/34816489/">two hours to decrease to background levels</a>, depending on your home’s ventilation.</p> <h2>Natural doesn’t mean risk free</h2> <p>But even if the levels of <a href="https://pubmed.ncbi.nlm.nih.gov/20659630/">VOCs in personal care products</a> are kept <a href="https://pubmed.ncbi.nlm.nih.gov/22406137/">within safe limits</a>, they can still cause discomfort and a variety of health issues, including irritation of the eyes and airways, migraines and asthmatic reactions, in those who’re <a href="https://enveurope.springeropen.com/articles/10.1186/s12302-020-00311-y">fragrance sensitive</a>. In the UK, <a href="https://link.springer.com/article/10.1007/s11869-018-00655-8">27% of the population</a> self reports as fragrance sensitive.</p> <p>It makes sense then that some people attempt to avoid potentially toxic synthetic chemicals in cosmetics by opting for “natural” or “clean” personal care products. But, <a href="https://enveurope.springeropen.com/articles/10.1186/s12302-020-00311-y">natural does not mean safer</a>.</p> <p>For instance, essential oils are often used in “natural” personal care products as fragrance. Essential oils, though, are a source of terpenes, some of which can be <a href="https://www.lung.org/blog/essential-oils-harmful-or-helpful">toxic if absorbed, inhaled or swallowed</a>.</p> <p>Indoor concentration of terpenes are often at levels where you can smell them but not high enough to cause <a href="https://pubmed.ncbi.nlm.nih.gov/28126407/">eye or respiratory tract irritation</a>. However, the terpenes from essential oils can react with other chemicals, such as ozone from outdoor air, producing <a href="https://pubmed.ncbi.nlm.nih.gov/32162221/">byproducts like formaldehyde, a known carcinogen</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/22250748/">allergens</a>.</p> <h2>Beauty salon safety</h2> <p>Beauty salons can be particularly risky environments for exposure to VOCs. <a href="https://www.mdpi.com/1660-4601/19/7/4176">Studies have found</a> contaminants such as formaldehyde, ammonia and <a href="https://www.gov.uk/government/publications/toluene-properties-incident-management-and-toxicology/toluene-toxicological-overview">toluene</a>, a potentially harmful ingredient used in many personal care products, at high levels in salons, putting staff who work there at the highest risk.</p> <p>Formaldehyde levels in some salons have reached <a href="https://pubmed.ncbi.nlm.nih.gov/31321727/">above safety limits</a>. <a href="https://www.dcceew.gov.au/environment/protection/npi/substances/fact-sheets/methyl-methacrylate#tabs-2">Methyl methacrylate</a>, which can cause skin irritation, allergic reactions and potential <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC3072694/">respiratory issues</a> has been <a href="https://pubmed.ncbi.nlm.nih.gov/30276513/">detected in the air of nail salons</a>.</p> <figure><iframe src="https://www.youtube.com/embed/ydRklqO01fE?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>These contaminants are not necessarily limited to the places in a salon <a href="https://pubmed.ncbi.nlm.nih.gov/23765035/">where a certain product is being used</a>. Beauty salons with poor ventilation are likely to expose workers and customers to <a href="https://pubmed.ncbi.nlm.nih.gov/29494285/">much higher levels of contaminants</a>. Some of the components of personal care products are known, harmful contaminants and carcinogens.</p> <p>Regulations specifically related to ventilation in environments where large volumes of these products are used do reduce exposures. For instance, studies show that after ventilation regulations came into effect in Boston, US in 2011, the <a href="https://pubmed.ncbi.nlm.nih.gov/31622145/">air quality inside nail salons improved</a>.</p> <p>When visiting your nail salon or hair stylist, check with them about their ventilation system and other steps they are taking to reduce exposure to VOCs.</p> <p>To limit exposure to potential VOCs at home when using personal care products, try to open windows and use extractor fans in wet rooms. Be especially careful when applying products to the face or when using a high temperature application – <a href="https://occup-med.biomedcentral.com/articles/10.1186/s12995-018-0213-x">high temperatures can increase emissions</a>.<!-- Below is The Conversation's page counter tag.

Why physical affection can boost your health

<p><em><a href="https://theconversation.com/profiles/viren-swami-241976">Viren Swami</a>, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a></em></p> <p>In the opening scene of <a href="https://www.youtube.com/watch?v=H9Z3_ifFheQ">Love, Actually</a>, Hugh Grant’s character says how, whenever he gets gloomy with the state of the world, he thinks about the arrivals gate at Heathrow airport. The reason is on screen: we see couples kissing, old friends embracing, children smiling and laughing as they jump into the arms of their parents.</p> <p>Airports are great places to really understand the importance of physical affection – hugging, kissing, cuddling, holding hands, or even just touching. But physical affection is ubiquitous in everyday life, too – and with good reason. Science shows that non-sexual physical affection produces more than just moments of joy – it also <a href="https://www.tandfonline.com/doi/abs/10.1080/03637751.2020.1805480?casa_token=DrsRLnkOANAAAAAA:u8gR6dQFL2Jp99tIr3m1Bcm14hc-EwVrbckdpuDX0HyWEBDrzoUcxNYpkCQzXP5oD_IhHqzYo7Fj">benefits</a> our mental and physical health.</p> <figure><iframe src="https://www.youtube.com/embed/PlyMXYys16U?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>Physical affection is one of the <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/j.1475-6811.1998.tb00157.x?casa_token=Rq8rCHwvKboAAAAA%3AxmDZvSXM6wTZuZzCCotRMro4nC_xcSbnw6Em8Od29q__XfYEhuwW9Iigpr2c8WlZJ_aMY4ng5m-DM40">most direct</a> and important ways that people communicate intimacy in their romantic relationships.

They’re also more comfortable allowing their partners to touch more of their bodies than strangers or friends. For example, most people are comfortable being touched on their <a href="https://www.pnas.org/doi/abs/10.1073/pnas.1519231112">thighs and abdomen</a> by their partner, but not by other people.</p> <p>Even how we touch our partners is different to how we touch other people. When participants in one study were asked to stroke their partner, a friend, a stranger, or an artificial arm, they did so more <a href="https://link.springer.com/article/10.1007/s10919-020-00334-2">slowly</a> with their partner. Slower strokes may may be experienced as more pleasant and <a href="https://academic.oup.com/jsm/article/14/5/645/6973562">erotic</a> than quicker strokes. Even just <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0203039">thinking</a> about physical affection from a partner evokes pleasant and erotic sensations.</p> <p>There is now strong evidence showing that physical contact is associated with better physical and mental health.

Touch interventions were especially helpful in reducing pain, depression and anxiety.</p> <h2>Couple’s therapy</h2> <p>Before you rush off to book yourself a massage, you should know that much of the evidence suggests the strongest benefits come from physical affection with romantic partners. Several studies have found that, in couples, physical affection is associated with a range of <a href="https://www.sciencedirect.com/science/article/pii/S0273229711000025?casa_token=ER4aGB-3vusAAAAA:IBMtXZdEpTywjizJ4kwcOPO2HykSwgaK3GS3qYWh5JTYvWJCLW-x1I3IYDYKbzLZ9aX8QIhOLlA">physiological</a> effects, including lower blood pressure and better immune responses.</p> <p>In couples, physical affection is also associated with better psychological <a href="https://journals.sagepub.com/doi/abs/10.1177/0146167213497592?casa_token=_OtVkA13hgkAAAAA%3AU6eWWQLI4CXadtUanBR1PEGBA-Xh8en3plwOayvC4KNF_Ybi8zyzHjheM1m2XWLxjgczoQstUEEbDg&amp;journalCode=pspc">wellbeing</a>. One study found that couples who <a href="https://link.springer.com/article/10.1007/s42761-021-00093-3">sleep-touched</a> – cuddling shortly before or after sleep – felt happier and calmer in the morning, which meant they were more likely to enjoy the company of their partners.</p> <p>Physical affection – including <a href="https://link.springer.com/article/10.1007/s10508-013-0190-1?correlationId=bbd6ba1a-a372-4cae-83b3-6d9ba5704f4e&amp;error=cookies_not_supported&amp;code=dc878548-1748-44ed-bf6b-36dd348ea060">kissing</a> and <a href="https://link.springer.com/article/10.1007/s10508-014-0305-3">affection after sex</a> – is also associated with greater relationship and <a href="https://link.springer.com/article/10.1007/s10508-016-0820-5">sexual satisfaction</a>, and better ratings of one’s relationship overall, which in turn contribute to better psychological wellbeing. And even when conflicts do occur, <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0203522">hugging</a> seems to reduce levels of negative mood in couples.</p> <p>Cuddle up, because there’s more. Receiving physical affection from a partner makes us feel psychologically stronger. One study found that women showed less activation in parts of the brain that respond to threat when <a href="https://journals.sagepub.com/doi/10.1111/j.1467-9280.2006.01832.x">holding their husband’s hand</a>.

Studies have shown that “<a href="https://onlinelibrary.wiley.com/doi/full/10.1002/ijop.12616">touch deprivation</a>” – the absence of touch – is associated with greater symptoms of depression and anxiety.

Affectionate touch is known to activate <a href="https://onlinelibrary.wiley.com/doi/epdf/10.1002/hbm.23679">reward centres</a> of the brain, which boosts our mood and promotes feelings of wellbeing.

Touching one’s partner in a caring manner helps to improve their mood and makes them feel loved, secure, and safe. As feelings of <a href="https://link.springer.com/article/10.1007/s10508-006-9071-1">connection</a>, trust, and belonging are strengthened through non-sexual physical signs of affection, negative effect is reduced and psychological well-being is improved.</p> <p>However, not everyone likes to be touched, even if it is by their romantic partners. Some people are “<a href="https://link.springer.com/article/10.1007/BF00990960">touch avoidant</a>” – and some people may actually be apprehensive about being touched. For instance, people with avoidant attachment styles – characterised by a discomfort with emotional closeness – often have very <a href="https://doi.org/10.1016/j.paid.2014.05.035">negative views about cuddling</a> and are more <a href="https://journals.sagepub.com/doi/10.1177/0146167295213008">hesitant</a> to touch their partners. Conversely, people with anxious attachment styles – characterised by a fear of abandonment – may desire <a href="https://journals.sagepub.com/doi/10.1177/0146167295213008">more touch</a> than they receive.</p> <p>But when couples have similar touch preferences, it can lead to greater attraction, <a href="https://journals.sagepub.com/doi/abs/10.1177/0265407520910791?casa_token=Q1265G4ynqsAAAAA%3AWuu40ji4ca-_TKKA7P2CeSqeTTFfYH-Bfz1c0pBUCJ6fD0_twBugXqg3Geon-ncaS2VhjfUTdp9HiQ&amp;journalCode=spra">closeness</a>, and commitment to one another. And if you’re looking for a fun way to incorporate non-sexual physical affection into your relationships, consider home massage. One study found that couples who <a href="https://www.mdpi.com/2254-9625/11/2/33">took turns massaging</a> each other at home felt a deeper connection with each other, and felt more relaxed and less stressed.<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/247858/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/viren-swami-241976">Viren Swami</a>, Professor of Social Psychology, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Tourists explain why they love “overrated” capital cities

<p dir="ltr">A group of travellers have explained why they love some capital cities that are often dubbed as “overrated”. </p> <p dir="ltr">On a dedicated travel thread on Reddit, one person asked the question, “Which capital city gets a lot of hate that you loved visiting?” which welcomed an influx of responses. </p> <p dir="ltr">A few capital cities were mentioned several times, one of which being the Greece capital of Athens. </p> <p dir="ltr">One Reddit user said they “avoided” Athens for a long time “because all I heard was negativity about it”.</p> <p dir="ltr">However, when they “finally went”, they say they “loved it” and “can't wait to go back”. </p> <p dir="ltr">Another person said they actually “loved” the city's “gritty feel” adding, “Incredible history at every turn, delicious affordable food, fun bars, cool music venues, neighbourhoods full of character and beautiful viewpoints.”</p> <p dir="ltr">Another capital that was mentioned was the Norwegian capital of Oslo, with one person saying the Scandinavian city was perfect for a short getaway. </p> <p dir="ltr">They wrote, “I’m not advising anyone to go for a long time but for a weekend trip, it’s lovely. The seaside is great with lots of beautiful modern architecture, the old town is picturesque, lots of trendy new places to eat and drink, some old castles to walk to and in general a really nice vibe and very walkable.”</p> <p dir="ltr">Washington D.C. was also mentioned with many people defending the city, with one person claiming “it’s generally other Americans who hate it.”</p> <p dir="ltr">One person wrote of the city, “We have great museums, food, way more nature than you’d expect for a city, and incredible music and dance scenes. It’s not just insufferable bureaucracy and politics.”</p> <p dir="ltr">The Belgian capital of Brussels was also mentioned, with the city often copping a lot of flack amongst travellers. </p> <p dir="ltr">However, many were quick to defend the city, as one person wrote,”I loved Brussels, it’s beautiful in places, has amazing museums, great beer, the EU Parliament is really interesting and the Atomium is awesome.”</p> <p dir="ltr"><em>Image credits: Shutterstock </em></p>

‘A virtual seat at the family table’: why older people are among the biggest users of social media

According to the <a href="https://wearesocial.com/au/blog/2024/01/digital-2024/">Digital 2024 report</a>, 78.3% of Australians regularly use platforms such as Facebook and Instagram – mainly for keeping in touch with friends and family.</p> <p>Perhaps surprisingly, a large proportion of these users are older people. For example, the Digital 2024 report also shows that 21.3% of Meta’s ad audience in Australia (on Messenger, Facebook and Instagram) are 55 years or older. This makes it the second largest age group after 25–34 year olds (25.4%).</p> <p>So what does research say about how social media affects older people’s social lives and wellbeing?</p> <h2>The growing presence of older adults on social media</h2> <p><a href="https://www.digitalinclusionindex.org.au/digital-inclusion-the-australian-context-in-2023/">The digital divide is shrinking</a> as older generations embrace social media. <a href="https://www.benetas.com.au/news/digial-habits-of-older-australians">According to data from earlier this year</a>, more than 70% of Australians aged 65 and older use social media to some degree.</p> <p><a href="https://www.aarp.org/content/dam/aarp/research/surveys_statistics/technology/2023/2023-tech-trends.doi.10.26419-2Fres.00584.001.pdf">Facebook remains the most popular</a> among this demographic, serving as a gateway to reconnect with family and long-lost friends.

Maintaining family ties.</strong> Social media provides older adults with a virtual seat at the family table. By viewing photos, videos and updates, <a href="https://theconversation.com/video-chats-can-ease-social-isolation-for-older-adults-during-coronavirus-pandemic-135890">they can remain engaged with their loved ones’ lives</a>, no matter the physical distance. Platforms such as WhatsApp and Facebook Messenger are particularly popular for private family group chats, enabling older adults to exchange messages and share moments in real time.</p> <p><strong>2.

Studies have shown such interactions can <a href="https://pubmed.ncbi.nlm.nih.gov/32700541/">bolster feelings of inclusion</a> and reduce loneliness, a significant concern for ageing populations.</p> <p><strong>3. Building new communities.</strong> Social media groups dedicated to specific interests such as gardening, photography or travel offer older adults opportunities to form new connections. <a href="https://www.emerald.com/insight/content/doi/10.1108/jkm-02-2021-0087/full/html">These virtual communities</a> are inclusive spaces where members exchange advice, share experiences and foster friendships based on shared hobbies.</p> <h2>Improved well-being</h2> <p>Social media’s ability to foster connection among older adults <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC8465959/#B7-healthcare-09-01143">directly impacts their wellbeing</a>.</p> <p>Regular online interactions can reduce feelings of loneliness and depression, providing a sense of purpose and belonging.</p> <p><a href="https://www.tandfonline.com/doi/abs/10.1080/10410236.2020.1859722">Research shows</a> active participation, such as posting photos, is associated with a feeling of competence in older users, which is related to well-being.

This demonstrates social media platforms’ broader potential beyond social interaction.</p> <h2>Online challenges</h2> <p>Despite its benefits, social media is not without challenges for older adults.</p> <p>For some, navigating the complex interface of platforms can be intimidating. <a href="https://www.mdpi.com/2076-0760/13/9/496">Our research</a> shows half of older adults feel anxious about using communication technologies, with older women experiencing more anxiety than older men.</p> <p>Issues such as <a href="https://apo.org.au/sites/default/files/resource-files/2021-08/apo-nid313717.pdf">privacy concerns, misinformation and online scams can also create barriers to engagement</a>. Additionally, while social media facilitates connection, it <a href="https://agsjournals.onlinelibrary.wiley.com/doi/10.1111/jgs.18546">cannot replace the depth of face-to-face interactions</a>.</p> <p><a href="https://journals.sagepub.com/doi/full/10.1177/14413582231187652">Our research</a> shows those with higher digital literacy are more likely to experience the positive effects of social media because of ongoing “self-socialisation” without having to interact with others, which might undermine learning and confidence.

Why the WHO has recommended switching to a healthier salt alternative

<p><em><a href="https://theconversation.com/profiles/xiaoyue-luna-xu-1388807">Xiaoyue (Luna) Xu</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> and <a href="https://theconversation.com/profiles/bruce-neal-69">Bruce Neal</a>, <a href="https://theconversation.com/institutions/george-institute-for-global-health-874">George Institute for Global Health</a></em></p> <p>This week the <a href="https://www.who.int/news-room/events/detail/2025/01/27/default-calendar/launch-of-the-who-guideline-on-the-use-of-lower-sodium-salt-substitutes">World Health Organization</a> (WHO) released new guidelines recommending people switch the regular salt they use at home for substitutes containing less sodium.</p> <p>But what exactly are these salt alternatives? And why is the WHO recommending this? Let’s take a look.</p> <h2>A new solution to an old problem</h2> <p>Advice to eat less salt (sodium chloride) is not new. It has been part of international and Australian guidelines <a href="https://www.ahajournals.org/doi/full/10.1161/HYPERTENSIONAHA.123.21343?rfr_dat=cr_pub++0pubmed&amp;url_ver=Z39.88-2003&amp;rfr_id=ori%3Arid%3Acrossref.org">for decades</a>. This is because evidence clearly shows the sodium in salt can <a href="https://www.who.int/news-room/fact-sheets/detail/salt-reduction">harm our health</a> when we eat too much of it.</p> <p>Excess sodium increases the risk of high blood pressure, which affects millions of Australians (around <a href="https://www.aihw.gov.au/reports/risk-factors/high-blood-pressure/contents/summary">one in three adults</a>). High blood pressure (<a href="https://www.healthdirect.gov.au/high-blood-pressure-hypertension">hypertension</a>) in turn increases the risk of heart disease, stroke and kidney disease, among other conditions.</p> <p>The WHO estimates <a href="https://www.who.int/news-room/events/detail/2025/01/27/default-calendar/launch-of-the-who-guideline-on-the-use-of-lower-sodium-salt-substitutes">1.9 million deaths</a> globally each year can be attributed to eating too much salt.</p> <p>The WHO recommends consuming no more than <a href="https://www.who.int/news-room/fact-sheets/detail/salt-reduction">2g of sodium daily</a>. However people eat on average more than double this, around <a href="https://www.who.int/news-room/events/detail/2025/01/27/default-calendar/launch-of-the-who-guideline-on-the-use-of-lower-sodium-salt-substitutes">4.3g a day</a>.</p> <p>In 2013, WHO member states <a href="https://iris.who.int/bitstream/handle/10665/366393/9789240069985-eng.pdf?sequence=1">committed to reducing</a> population sodium intake <a href="https://www.who.int/news/item/09-03-2023-massive-efforts-needed-to-reduce-salt-intake-and-protect-lives">by 30% by 2025</a>. But cutting salt intake has proved very hard. Most countries, including Australia, will not meet the WHO’s goal for reducing sodium intake <a href="https://www.sciencedirect.com/science/article/pii/S2161831322004690?via%3Dihub_">by 2025</a>. The WHO has since <a href="https://www.who.int/news-room/events/detail/2025/01/27/default-calendar/launch-of-the-who-guideline-on-the-use-of-lower-sodium-salt-substitutes">set the same target for 2030</a>.</p> <p>The difficulty is that eating less salt means accepting a less salty taste. It also requires changes to established ways of preparing food. This has proved too much to ask of people making food at home, and too much for the food industry.</p> <h2>Enter potassium-enriched salt</h2> <p>The main lower-sodium salt substitute is called potassium-enriched salt. This is salt where some of the sodium chloride has been replaced with potassium chloride.</p> <p>Potassium is an <a href="https://www.healthdirect.gov.au/potassium">essential mineral</a>, playing a key role in all the body’s functions. The high potassium content of fresh fruit and vegetables is one of the main reasons they’re so good for you. While people are eating more sodium than they should, many don’t get enough potassium.</p> <p>The WHO recommends a daily potassium intake of 3.5g, but on the whole, people in most countries consume significantly <a href="https://www.ahajournals.org/doi/full/10.1161/HYPERTENSIONAHA.123.21343?rfr_dat=cr_pub++0pubmed&amp;url_ver=Z39.88-2003&amp;rfr_id=ori%3Arid%3Acrossref.org">less than this</a>.</p> <p>Potassium-enriched salt benefits our health by cutting the amount of sodium we consume, and increasing the amount of potassium in our diets. Both help to <a href="https://theconversation.com/this-salt-alternative-could-help-reduce-blood-pressure-so-why-are-so-few-people-using-it-221409">lower blood pressure</a>.</p> <p>Switching regular salt for potassium-enriched salt has been shown to <a href="https://heart.bmj.com/content/108/20/1608">reduce the risk</a> of heart disease, stroke and premature death in large trials around the world.</p> <p>Modelling studies have projected that population-wide switches to potassium-enriched salt use would prevent hundreds of thousands of deaths from cardiovascular disease (such as heart attack and stroke) each year in <a href="https://www.bmj.com/content/369/bmj.m824.long">China</a> and <a href="https://www.ahajournals.org/doi/10.1161/HYPERTENSIONAHA.122.19072?url_ver=Z39.88-2003&amp;rfr_id=ori:rid:crossref.org&amp;rfr_dat=cr_pub%20%200pubme">India</a> alone.</p> <p>The key advantage of switching rather than cutting salt intake is that potassium-enriched salt can be used as a direct one-for-one swap for regular salt. It looks the same, works for seasoning and in recipes, and most people don’t notice any important <a href="https://theconversation.com/this-salt-alternative-could-help-reduce-blood-pressure-so-why-are-so-few-people-using-it-221409">difference in taste</a>.</p> <p>In the <a href="https://www.nejm.org/doi/full/10.1056/NEJMoa2105675">largest trial</a> of potassium-enriched salt to date, more than 90% of people were still using the product after five years.</p> <h2>Making the switch: some challenges</h2> <p>If fully implemented, this could be one of the most consequential pieces of advice the WHO has ever provided.</p> <p>Millions of strokes and heart attacks could be prevented worldwide each year with a simple switch to the way we prepare foods. But there are some obstacles to overcome before we get to this point.</p> <p>First, it will be important to balance the benefits and the risks. For example, people with <a href="https://www.ahajournals.org/doi/full/10.1161/HYPERTENSIONAHA.123.21343?rfr_dat=cr_pub++0pubmed&amp;url_ver=Z39.88-2003&amp;rfr_id=ori%3Arid%3Acrossref.org">advanced kidney disease</a> don’t handle potassium well and so these products are not suitable for them. This is only <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC8177747/">a small proportion</a> of the population, but we need to ensure potassium-enriched salt products are labelled with appropriate warnings.</p> <p>A key challenge will be making potassium-enriched salt more affordable and accessible. Potassium chloride is more expensive to produce than sodium chloride, and at present, potassium-enriched salt is mostly sold as a niche health product at a <a href="https://publichealth.jmir.org/2021/7/e27423">premium price</a>.</p> <p>If you’re looking for it, <a href="https://www.georgeinstitute.org/switchthesalt#card-with-text-2166">salt substitutes</a> may also be called low-sodium salt, potassium salt, heart salt, mineral salt, or sodium-reduced salt.</p> <p>A <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC8319774/">review published in 2021</a> found low sodium salts were marketed in only 47 countries, mostly high-income ones. Prices ranged from the same as regular salt to almost 15 times higher.</p> <p>An expanded supply chain that produces much more food-grade potassium chloride will be needed to enable wider availability of the product. And we’ll need to see potassium-enriched salt on the shelves next to regular salt so it’s easy for people to find.</p> <p>In countries like Australia, about 80% of the salt we eat comes from <a href="https://www.foodstandards.gov.au/consumer/nutrition/sodium-salt/salthowmuch">processed foods</a>. The WHO guideline falls short by not explicitly prioritising a switch for the salt used in food manufacturing.</p> <p>Stakeholders working with government to encourage food industry uptake will be essential for maximising the health benefits.<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/248436/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/xiaoyue-luna-xu-1388807">Xiaoyue (Luna) Xu</a>, Scientia Lecturer, School of Population Health, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> and <a href="https://theconversation.com/profiles/bruce-neal-69">Bruce Neal</a>, Executive Director, George Institute Australia, <a href="https://theconversation.com/institutions/george-institute-for-global-health-874">George Institute for Global Health</a></em></p> <p><em>Image credits: Shutterstock</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

New research reveals that, as people age, <a href="https://psycnet.apa.org/fulltext/2025-00409-001.html">they do tend to become less narcissistic</a>.</p> <p>Narcissism is a complex, <a href="https://theconversation.com/narcissism-why-its-less-obvious-in-women-than-in-men-but-can-be-just-as-dangerous-231392">multi-dimensional personality trait</a>, which captures features beyond vanity and self-absorption. Emerging <a href="https://doi.org/10%20.1177/09637214211044109">research</a> suggests there are <a href="https://doi.org/10.1111/jopy.12464">three different features</a> (called “dimensions”) of narcissism: agentic, antagonistic and neurotic.</p> <p>Agentic narcissism involves the need for admiration and feelings of superiority. Antagonistic narcissism is characterised by the exploitation of, and a lack of empathy towards, other people. Finally, neurotic narcissism refers to being sensitive and having difficulties regulating one’s emotions.</p> <p>In order to fully understand how narcissism develops, the new study looked at all the three features. They analysed data from 51 longitudinal studies (meaning studies which follow participants over time), all of which measured how participants’ levels of narcissism changed. The researchers coded whether each study measured one or more of three different dimensions of narcissism.</p> <p>To select the studies, the team used the American Psychiatric Association (APA) PsychInfo database of papers, searching for terms including “narcissism” and “narcissistic”. Each article was reviewed by two coders who were not part of the research team. The coders independently selected the studies based on details including sample size, gender ratio, measurement used, and the country in which the sample was collected.</p> <p>This robust procedure generated a large dataset which comprised of 37,247 participants (52% female) ranging from ages eight to 77 years. The majority of the participants were from western Europe, the US and Canada.</p> <p>Overall, the researchers found that all three dimensions of narcissism declined across the life span. There was a small decline for agentic narcissism and a moderate reduction for antagonistic and neurotic narcissism. The rate of change did not differ based on gender, age or birth cohort.</p> <p>Interestingly, the researchers also found that people’s narcissism relative to that of their peers remained consistent over the life span. In other words, people who were more narcissistic than average as children remained more narcissistic than average as adults.</p> <h2>Changing roles</h2> <p>What, then, are the mechanisms involved in people becoming less narcissistic as they go through life? One possible factor is to do with changing social roles across our lifespan. It is important to remember that narcissism exists along a spectrum, with the lower end being helpful (a healthy balance of self-esteem and confidence) and the higher end being unhelpful and malignant (fluctuating self-esteem, aggression and lack of empathy).</p> <p>It is possible that our <a href="https://psycnet.apa.org/record/2008-11667-014">personalities adapt</a> when we make the transition into adulthood – which involves important individual and social responsibilities such as commitment to a relationship, leadership roles, or becoming a parent. After all, it is hard to successfully look after children or managing other people if you are too focused on yourself.</p> <p>Even in old age, narcissism continues to decline. That may be because people tend to follow paths which encourages altruistic values as opposed to egoistic values, such as commitment to their family and grandchildren. By this age, most people have probably also learned the hard way the punishing consequences of being hostile to others.</p> <p>This view is supported by <a href="https://journals.sagepub.com/doi/10.1111/j.1467-8721.2008.00543.x">other research</a> suggesting that people develop more mature personality features in general over time, including becoming more emotionally stable, conscientious (hardworking and dutiful) and agreeable (kind and altruistic). As narcissism is considered to be the opposite of maturity, we expect, in theory, that features of narcissism (particularly the antagonistic and neurotic dimensions) to decrease across the life span.</p> <p>However, narcissism can increase over time in some people. Research shows that some aspects of narcissism, such as exploitation of others and lack of empathy, can increase when people assume positions of power. This is <a href="https://iaap-journals.onlinelibrary.wiley.com/doi/abs/10.1111/j.1464-0597.2006.00226.x">particularly relevant</a> at work and <a href="https://www.sciencedirect.com/science/article/abs/pii/S0191886920304360">in relationships</a>.</p> <p>And let’s not forget that some people are simply just more narcissistic than others. Just because you’re 70 doesn’t mean you can’t be self-centered, it just means you might be less narcissistic than you once were.</p> <p>This may be partly down to genetics, but it may also be the case that certain environments exacerbate existing features of narcissism. For instance, certain parenting styles – including being neglectful, overprotective, and/or providing excessive praise by putting the child on a pedestal – have <a href="https://www.sciencedirect.com/science/article/abs/pii/S0191886920304359">all been linked</a> to children developing narcissism in adulthood, suggesting a good balance is key.</p> <p>It is important to understand more fully how narcissism changes across life. That is not least because we know that it can have a detrimental effects on the individual and the people around them.<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/234437/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/ava-green-1396648"><em>Ava Green</em></a><em>, Lecturer in Forensic Psychology, <a href="https://theconversation.com/institutions/city-st-georges-university-of-london-1047">City St George's, University of London</a></em></p> <p><em>Image credits: Shutterstock</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

How we diagnose and define obesity is set to change – here’s why, and what it means for treatment

Brown</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a></em></p> <p>Obesity is <a href="https://www.niddk.nih.gov/health-information/weight-management/adult-overweight-obesity/health-risks#:%7E:text=Having%20overweight%20or%20obesity%20increases,the%20cells%20in%20your%20body">linked to</a> many common diseases, such as type 2 diabetes, heart disease, fatty liver disease and knee osteoarthritis.</p> <p>Obesity is currently defined using a person’s body mass index, or BMI. This is <a href="https://www.who.int/news-room/fact-sheets/detail/obesity-and-overweight">calculated</a> as weight (in kilograms) divided by the square of height (in metres). In people of European descent, the BMI for obesity is 30 kg/m² and over.</p> <p>But the risk to health and wellbeing is not determined by weight – and therefore BMI – alone. We’ve been part of a global collaboration that has spent the past two years discussing how this should change. Today we publish how we think obesity should be defined and why.</p> <p>As we outline in <a href="https://www.thelancet.com/commissions/clinical-obesity">The Lancet</a>, having a larger body shouldn’t mean you’re diagnosed with “clinical obesity”. Such a diagnosis should depend on the level and location of body fat – and whether there are associated health problems.</p> <h2>What’s wrong with BMI?</h2> <p>The risk of ill health depends on the relative percentage of fat, bone and muscle making up a person’s body weight, as well as where the fat is distributed.</p> <p>Athletes with a relatively high muscle mass, for example, may have a higher BMI. Even when that athlete has a BMI over 30 kg/m², their higher weight is due to excess muscle rather than excess fatty tissue.</p> <p>People who carry their excess fatty tissue <a href="https://www.abc.net.au/news/health/2017-09-06/waist-size-why-it-matters-and-when-its-a-risk/8839708">around their waist</a> are at greatest risk of the health problems associated with obesity.</p> <p>Fat stored deep in the abdomen and around the internal organs can release damaging molecules into the blood. These can then <a href="https://theconversation.com/body-fat-deep-below-the-surface-is-a-toxic-risk-especially-for-your-heart-146307">cause problems</a> in other parts of the body.</p> <p>But BMI alone does not tell us whether a person has health problems related to excess body fat. People with excess body fat don’t always have a BMI over 30, meaning they are not investigated for health problems associated with excess body fat. This might occur in a very tall person or in someone who tends to store body fat in the abdomen but who is of a “healthy” weight.</p> <p>On the other hand, others who aren’t athletes but have excess fat may have a high BMI but no associated health problems.</p> <p>BMI is therefore an imperfect tool to help us diagnose obesity.</p> <h2>What is the new definition?</h2> <p>The goal of the <a href="https://pubmed.ncbi.nlm.nih.gov/36878238">Lancet Diabetes &amp; Endocrinology Commission on the Definition and Diagnosis of Clinical Obesity </a>was to develop an approach to this definition and diagnosis. The commission, established in 2022 and led from King’s College London, has brought together 56 experts on aspects of obesity, including people with lived experience.</p> <p>The commission’s <a href="https://www.thelancet.com/commissions/clinical-obesity">definition and new diagnostic criteria</a> shifts the focus from BMI alone. It incorporates other measurements, such as waist circumference, to confirm an excess or unhealthy distribution of body fat.</p> <p>We define two categories of obesity based on objective signs and symptoms of poor health due to excess body fat.</p> <p><strong>1. Clinical obesity</strong></p> <p>A person with clinical obesity has signs and symptoms of ongoing organ dysfunction and/or difficulty with day-to-day activities of daily living (such as bathing, going to the toilet or dressing).</p> <p>There are 18 diagnostic criteria for clinical obesity in adults and 13 in children and adolescents. These include:</p> <ul> <li> <p>breathlessness caused by the effect of obesity on the lungs</p> </li> <li> <p>obesity-induced heart failure</p> </li> <li> <p>raised blood pressure</p> </li> <li> <p>fatty liver disease</p> </li> <li> <p>abnormalities in bones and joints that limit movement in children.</p> </li> </ul> <p><strong>2. Pre-clinical obesity</strong></p> <p>A person with pre-clinical obesity has high levels of body fat that are not causing any illness.</p> <p>People with pre-clinical obesity do not have any evidence of reduced tissue or organ function due to obesity and can complete day-to-day activities unhindered.</p> <p>However, people with pre-clinical obesity are generally at higher risk of developing diseases such as heart disease, some cancers and type 2 diabetes.</p> <h2>What does this mean for obesity treatment?</h2> <p>Clinical obesity is a disease requiring access to effective health care.</p> <p>For those with clinical obesity, the focus of health care should be on improving the health problems caused by obesity. People should be offered evidence-based treatment options after discussion with their health-care practitioner.</p> <p><a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(24)01210-8/abstract">Treatment</a> will <a href="https://www.thelancet.com/journals/landia/article/PIIS2213-8587(22)00047-X/fulltext">include</a> management of obesity-associated complications and may include specific obesity treatment aiming at decreasing fat mass, such as:</p> <ul> <li> <p>support for <a href="https://www.obesityevidencehub.org.au/collections/treatment/behavioural-interventions-for-the-management-of-overweight-and-obesity-in-adults">behaviour change</a> <a href="https://www.obesityevidencehub.org.au/collections/treatment/managing-overweight-and-obesity-in-children-and-adolescents">around</a> diet, physical activity, sleep and screen use</p> </li> <li> <p>obesity-management medications to reduce appetite, lower weight and <a href="https://www.obesityevidencehub.org.au/collections/treatment/medication-and-surgery-for-the-treatment-of-overweight-and-obesity-in-adults">improve health</a> outcomes such as blood glucose (sugar) and blood pressure</p> </li> <li> <p>metabolic <a href="https://theconversation.com/thinking-about-bariatric-surgery-for-weight-loss-heres-what-to-consider-184153">bariatric surgery</a> to treat obesity or reduce weight-related health complications.</p> </li> </ul> <h2>Should pre-clinical obesity be treated?</h2> <p>For those with pre-clinical obesity, health care should be about risk-reduction and prevention of health problems related to obesity.</p> <p>This may require health counselling, including support for health behaviour change, and monitoring over time.</p> <p>Depending on the person’s individual risk – such as a family history of disease, level of body fat and changes over time – they may opt for one of the obesity treatments above.</p> <p>Distinguishing people who don’t have illness from those who already have ongoing illness will enable personalised approaches to obesity prevention, management and treatment with more appropriate and cost-effective allocation of resources.</p> <h2>What happens next?</h2> <p>These new criteria for the diagnosis of clinical obesity will need to be adopted into national and international clinical practice guidelines and a range of obesity strategies.</p> <p>Once adopted, training health professionals and health service managers, and educating the general public, will be vital.</p> <p>Reframing the narrative of obesity may help eradicate misconceptions that contribute to stigma, including making false assumptions about the health status of people in larger bodies. A better understanding of the biology and health effects of obesity should also mean people in larger bodies are not blamed for their condition.</p> <p>People with obesity or who have larger bodies should expect personalised, evidence-based assessments and advice, free of stigma and blame.<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/245164/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/louise-baur-5284"><em>Louise Baur</em></a><em>, Professor, Discipline of Child and Adolescent Health, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/john-b-dixon-11630">John B.

Why do some people’s hair and nails grow quicker than mine?

<p><em><a href="https://theconversation.com/profiles/michelle-moscova-310728">Michelle Moscova</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a></em></p> <p>Throughout recorded history, our hair and nails played an important role in signifying who <a href="https://www.psychiatrictimes.com/view/gender-culture-and-social-constructs-in-body-focused-repetitive-behaviors">we are and our social status</a>. You could say, they separate the caveman from businessman.</p> <p>It was no surprise then that many of us found a new level of appreciation for our hairdressers and nail artists during the COVID lockdowns. Even Taylor Swift reported <a href="https://abcnews.go.com/GMA/Culture/taylor-swift-reveals-shes-cutting-hair-covid-19/story?id=74757540&amp;t">she cut her own hair during lockdown</a>.</p> <p>So, what would happen if all this hair and nail grooming got too much for us and we decided to give it all up. Would our hair and nails just keep on growing?</p> <p>The answer is yes. The hair on our head grows, on average, <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9917549/">1 centimeter per month</a>, while our fingernails grow an average of just <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC11436330/">over 3 millimetres</a>.</p> <p>When left unchecked, our hair and nails can grow to impressive lengths. Aliia Nasyrova, known as the Ukrainian Rapunzel, holds the world record for the longest locks on a living woman, which measure an <a href="https://www.youtube.com/watch?v=1TdlEIQdVwo&amp;t=81s">impressive 257.33 cm</a>.</p> <p>When it comes to record-breaking fingernails, Diana Armstrong from the United States holds that record <a href="https://www.youtube.com/watch?v=nwql937j-7Q">at 1,306.58 cm</a>.</p> <p>Most of us, however, get regular haircuts and trim our nails – some with greater frequency than others. So why do some people’s hair and nails grow more quickly?</p> <h2>Remind me, what are they made out of?</h2> <p>Hair and nails are made mostly from keratin. Both grow from matrix cells below the skin and grow through different patterns of cell division.</p> <p>Nails grow steadily from the matrix cells, which sit under the skin at the base of the nail. These cells divide, pushing the older cells forward. As they grow, <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC5383514/">the new cells slide</a> along the nail bed – the flat area under the fingernail which looks pink because of its rich blood supply.</p> <p>A hair also starts growing from the matrix cells, eventually forming the visible part of the hair – the shaft. The hair shaft grows from a root that sits under the skin and is wrapped in a sac known as the hair follicle.</p> <p>This sac has a nerve supply (which is why it hurts to pull out a hair), oil-producing glands that lubricate the hair and a tiny muscle that <a href="https://www.ncbi.nlm.nih.gov/books/NBK546248/">makes your hair stand up</a> when it’s cold.</p> <p>At the follicle’s base is the hair bulb, which contains the all-important hair papilla that supplies blood to the follicle.</p> <p>Matrix cells near the papilla divide to produce new hair cells, which then harden and form the hair shaft. As the new hair cells are made, the hair is pushed up above the skin <a href="https://www.jidonline.org/article/S0022-202X(15)41553-2/fulltext">and the hair grows</a>.</p> <p>But the papilla also plays an integral part in regulating hair growth cycles, as it sends signals to the stem cells to move to the base of the follicle and form a hair matrix. Matrix cells then get signals to divide and start a new growth phase.</p> <h2>Unlike nails, our hair grows in cycles</h2> <p>Scientists have identified <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9917549/">four phases of hair growth</a>, the:</p> <ol> <li> <p>anagen or growth phase, which lasts between two and eight years</p> </li> <li> <p>catagen or transition phase, when growth slows down, lasting around two weeks</p> </li> <li> <p>telogen or resting phase, when there is no growth at all. This usually lasts two to three months</p> </li> <li> <p>exogen or shedding phase, when the hair falls out and is replaced by the new hair growing from the same follicle. This starts the process all over again.</p> </li> </ol> <figure class="align-center "><img src="https://images.theconversation.com/files/637402/original/file-20241210-15-gtv259.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/637402/original/file-20241210-15-gtv259.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=308&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/637402/original/file-20241210-15-gtv259.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=308&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/637402/original/file-20241210-15-gtv259.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=308&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/637402/original/file-20241210-15-gtv259.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=387&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/637402/original/file-20241210-15-gtv259.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=387&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/637402/original/file-20241210-15-gtv259.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=387&amp;fit=crop&amp;dpr=3 2262w" alt="Stages of hair growth graphic" /><figcaption><span class="caption">Hair follicles enter these phases at different times so we’re not left bald.</span> <span class="attribution"><a class="source" href="https://www.shutterstock.com/image-vector/stages-hair-growth-cycle-vector-isolated-2433656865">Mosterpiece/Shutterstock</a></span></figcaption></figure> <p>Each follicle goes through this cycle <a href="https://www.longdom.org/open-access/a-note-on-the-human-hair-follicle-from-the-origin-to-the-death-93871.html?t">10–30 times in its lifespan</a>.</p> <p>If all of our hair follicles grew at the same rate and entered the same phases simultaneously, there would be times when we would all be bald. That doesn’t usually happen: at any given time, only one in ten hairs is in the resting phase.</p> <p>While we lose about <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9917549/">100–150 hairs daily</a>, the average person has <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9917549/">100,000 hairs</a> on their head, so we barely notice this natural shedding.</p> <h2>So what affects the speed of growth?</h2> <p>Genetics is the most significant factor. While hair growth rates vary between individuals, they tend to be <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4201279/">consistent among family members</a>.</p> <p>Nails are also influenced by genetics, as siblings, especially identical twins, tend to have <a href="https://link.springer.com/referenceworkentry/10.1007/978-3-319-26594-0_121-1">similar nail growth rates</a>.</p> <p>But there are also other influences.</p> <p><a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9917549/">Age makes a difference</a> to hair and <a href="https://link.springer.com/referenceworkentry/10.1007/978-3-319-26594-0_121-1">nail</a> growth, even in healthy people. Younger people generally have faster growth rates because of the slowing metabolism and cell division that comes with ageing.</p> <p><a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC7432488/">Hormonal changes</a> can have an impact. Pregnancy often <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC7432488/">accelerates</a> hair and nail growth rates, while menopause and high levels of the stress hormone cortisol can <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC7432488/">slow growth rates</a>.</p> <p>Nutrition also changes <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6380979/">hair</a> and <a href="https://ijdvl.com/nails-in-nutritional-deficiencies/?t">nail</a> strength and growth rate. While hair and nails are made mostly of keratin, they also contain water, fats and various minerals. As hair and nails keep growing, these minerals need to be replaced.</p> <p>That’s why a balanced diet that includes sufficient nutrients to support your hair and nails is essential for maintaining their health.</p> <p>Nutrient deficiencies may contribute to hair loss and nail breakage by disrupting their growth cycle or weakening their structure. Iron and zinc deficiencies, for example, have both been linked to <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6380979/">hair loss</a> and <a href="https://ijdvl.com/nails-in-nutritional-deficiencies/?t">brittle nails</a>.</p> <p>This may explain why thick hair and strong, well-groomed nails have long been associated with perception of good health and high status.</p> <p>However, not all perceptions are true.</p> <h2>No, hair and nails don’t grow after death</h2> <p>A persistent myth that may relate to <a href="https://www.britannica.com/topic/vampire">the legends of vampires</a> is that hair and nails continue to grow after we die.</p> <p>In reality, they only <em>appear</em> to do so. As the body dehydrates after death, the skin shrinks, making hair and nails <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC2151163/">seem longer</a>.</p> <p>Morticians are well aware of this phenomenon and some <a href="https://www.adomonline.com/mortuary-man-reveals-how-he-handles-nails-of-the-dead/?t">inject tissue filler</a> into the deceased’s fingertips to minimise this effect.</p> <p>So, it seems that living or dead, there is no escape from the never-ending task of caring for our hair and nails.<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/241556/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/michelle-moscova-310728">Michelle Moscova</a>, Adjunct Associate Professor, Anatomy, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Why the royal family is set to receive an eye-watering pay increase

<p>The members of the British royal family are set to receive a record-breaking pay increase, funded by British taxpayers. </p> <p>From April 2025, the amount the royals will receive from the Sovereign Grant - funded by the UK’s public purse – will jump by a whopping £45 million (A$88 million), to £132 million ($260 million).</p> <p>Not everyone is happy about this enormous pay increase, as CEO of Republic Graham Smith said that while the UK remains in the clutches of the cost of living crisis, it is not the time for such a hefty increase to one of the richest families in the world. </p> <p>“This is public money, all of this money comes from the government, at a time when the government is not able to properly fund schools, hospitals police … It is scandalous,” Smith told <em><a href="https://www.townandcountrymag.com/society/tradition/a63330811/british-royal-family-money-finances-2025/" target="_blank" rel="noopener">Town &amp; Country</a></em>. </p> <p>“Not only should it not be going up at all, it should be going down.”</p> <p>The increase was first announced last year, with Buckingham Palace officials saying at the time that a huge chunk of that extra cash will be put towards the £369 million ($728 million) bill for long-planned, necessary Palace renovations.</p> <p>The exact amount that is being allocated from this year’s Grant for the work has not been made public.</p> <p>The Grant was established in 2012 in order to help the royal family pay for expenses related to their official duties, with the vast majority usually spent on property maintenance and staffing.</p> <p>When the Grant first came into effect, there were many more working royals which required a larger pool of funding. </p> <p>Now that the royal roster has been stripped back, royal author Richard Palmer believes the public is now “getting less for their money”.</p> <p>He told <em>Town &amp; Country</em>, “I do think that the monarchy in general does a good job for the country and is part of the glue that binds us all together but that doesn’t mean that as an institution, as individuals, they should be able to avoid criticism. They are not above scrutiny.”</p> <p><em>Image credits: Shutterstock </em></p>

Why one pizza shop is charging almost $200 for a divisive topping

<p dir="ltr">A trendy pizzeria is charging customers almost $200 AUD for one divisive pizza topping as they reignite the debate of putting pineapple on pizza. </p> <p dir="ltr">Lupa Pizza in Norwich in the UK have reluctantly added Hawaiian pizza to their menu, but the ham and pineapple combo comes with a catch.</p> <p dir="ltr">Diners will be charged £100 ($198 AUD) for it, with the restaurant taking to social media to share the news of the hefty price. </p> <p dir="ltr">"🍍🍕 Pineapple on pizza — love it or hate it?" they wrote. "We're not so keen, but if you are, it's now on our Deliveroo menu for £100 ($198). 🤷‍♂️”</p> <p dir="ltr">"Order the champagne too! Go on, you monster!" they added.</p> <p dir="ltr">The restaurant's owner and chef have defended the cost for a simple reason: their shared dislike of pineapple on pizza.</p> <p dir="ltr">"I absolutely loathe pineapple on a pizza," Francis Woolf, the co-owner of Lupa Pizza, told the <em>Norwich Evening News</em>.</p> <p dir="ltr">Head chef Quin Jianoran agreed, adding, "I love a piña colada, but pineapple on pizza? Never. I'd rather put a bloody strawberry on one than that tropical menace.”</p> <p dir="ltr">Their views, however, are not shared with the majority of the British public. In the most recent YouGov survey on the subject, 53 percent of Britons admitted they enjoyed the taste of pineapple on pizza, while 41 percent of people do not.</p> <p dir="ltr">Lupa agreed to feature the Hawaiian special on its main menu if the people of Norwich voted in favour of the combination in an online poll, which closes on January 24th.</p> <p dir="ltr">“If pineapple wins the vote, I’ll make it,” said Mr Jianoran. “But I won’t be happy about it. And I might charge £200 next time.”</p> <p dir="ltr"><em>Image credits: Instagram </em></p>

Pilot explains why airplane mode on phones is so important

<p>A seasoned pilot has explained the real reason why your phone needs to be on airplane mode for the duration of your next flight. </p> <p>The pilot broke down the precaution in a video he posted to TikTok, with the explanation racking up over 2 million views. </p> <p>“The plane mode button on your phone is not a conspiracy,” declared the pilot, before reassuring passengers that using your phone onboard won't cause the plane to “fall out of the sky” or even really “mess with the systems on board”.</p> <p>However, if too many flyers choose to use their phones all at once, it can inadvertently mess with the pilots’ radio communications with the control tower.</p> <p>“If you have an aircraft with 70, 80, 150 people on board, and even three or four people’s phones start to try to make a connection to a radio tower for an incoming phone call, it sends out radio waves,” the captain explained. </p> <p>“There’s the potential that those radio waves can interfere with the radio waves of the headset that the pilots are using.”</p> <p>He recalled a recent flight where he was using his headset to get “clearance on which way to go” and the message interference made it feel like there was a “mosquito” in his ear.</p> <p>“It’s definitely not the end of the world but it’s pretty annoying when you’re trying to copy down instructions and it sounds like there’s a wasp or something flying around,” the pilot declared. </p> <p>“So if you’re ever curious why you’ve got to put on plane mode, that’s why.”</p> <p><em>Image credits: Shutterstock</em></p>

Why does grass make my skin itch?

<p><em><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></em></p> <p>So, you’ve enjoyed a picnic in the sunshine. Or you’ve sat on the grass for a twilight concert. But you’ve come away with itchy and scratchy skin.</p> <p>Could you have an allergy to grass? Or is something else going on?</p> <h2>Grass has tiny hairs</h2> <p>One possible reason we get a rash is the physical structure of grass itself.</p> <p><a href="https://bmcplantbiol.biomedcentral.com/articles/10.1186/s12870-021-02840-x">Blades of grass</a> are covered in tiny “hairs” (called trichomes), which you can view under a microscope.</p> <p>These help protect the grass from being eaten by insects or animals, damaged by ultraviolet rays or losing too much water.</p> <p>Trichomes can also cause tiny scratches to the skin and the skin reacts by becoming red and may feel itchy.</p> <p>Some species of grass are also firmer or stiffer so may feel more “scratchy” when people sit on them.</p> <p>Skin is a complex organ and is linked to the immune system. When irritated, the skin and immune system recognise something is happening and release complex chemicals that can <a href="https://www.jacionline.org/article/S0091-6749%2815%2900575-8/fulltext">cause redness and itching</a>.</p> <p>People with dry, red, itchy skin conditions often find their skin is extra sensitive to grass and other irritants like fertilisers or sprays. For example, if you have eczema (also called dermatitis) your skin looks and feels dry, as your <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC5849435/">skin barrier is damaged</a>.</p> <h2>Could it be an allergy?</h2> <p>Grass allergy involves <a href="https://www.allergy.org.au/patients/allergic-rhinitis-hay-fever-and-sinusitis/pollen-allergy">aero-allergens</a>, that is, the grass pollen in the air. Symptoms include runny or a stuffy nose, itchy nose and eyes and even itchy ears.</p> <p>If you have these symptoms allergy specialists <a href="https://www.allergy.org.au/patients/allergy-testing/allergy-testing">may perform a skin prick test</a> to identify particular aero-allergen triggers.</p> <p>After the allergist takes your detailed history, drops of various allergens are placed on the forearm, along with a positive and negative control. A sterile lancet pricks the skin through the drop. After 15 minutes the test is read, with positive reactions showing a “wheal and flare” response (a lump like a mosquito bite and redness). The allergist then interprets the findings.</p> <p>But, in the absence of hay fever-like symptoms, dermatologists may perform <a href="https://dermnetnz.org/topics/patch-tests">allergy patch testing</a> to investigate contact allergies (dermatitis) to specific plants, for example <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9542089/"><em>Compositae</em></a>.</p> <p>In a patch test the dermatologist places a series of small chambers (or sticky dots) on the back, each one containing a different potential allergen. The test takes several days to produce results. If a reaction develops under a test chamber, the dermatologist may confirm allergic contact dermatitis.</p> <p>But definitive results are tricky as these two allergy tests can’t tell you if your rash is from physical irritation – such as the tiny scratches – rather than an allergy.</p> <h2>How can I avoid it?</h2> <p>The best way to reduce physical irritation problems with grass it to limit contact. This could involve simple things like wearing long sleeves or pants, or sitting on a rug or towel.</p> <p>Many Australians do have dry skin, but do not often realise how dry it is. So, applying a <a href="https://toolkit.eczemasupport.org.au/my-self/moisturising-creams/">basic thick moisturiser</a> to the face and body skin can help place a barrier between the grass and the skin. Sunscreen is also recommended when outdoors.</p> <p>For people who have dry, red or itchy skin conditions or those who experience itchiness when sitting on the grass, taking <a href="https://allergyfacts.org.au/allergy-treatments-antihistamine/">antihistamines</a> a minimum of 30 minutes before you sit on the grass may help lessen the itchiness.</p> <h2>How can I calm my skin?</h2> <p>If you do develop a an irritant rash, here are a few tips. You could try</p> <ul> <li> <p>taking an <a href="https://allergyfacts.org.au/allergy-treatments-antihistamine/">antihistamine</a></p> </li> <li> <p>rinsing skin with tepid water</p> </li> <li> <p>washing off the potential irritants with a non-soap-based bland body cleanser <a href="https://toolkit.eczemasupport.org.au/my-self/bathing-showering-and-washing-clothes/">can be helpful</a>. Then, re-apply a layer of thick, bland, fragrance-free moisturiser.</p> </li> </ul> <p>If none of these measures help, see a pharmacist for advice on using an appropriate strength cortisone cream which may <a href="https://www.healthdirect.gov.au/rashes">help reduce</a> the symptoms.</p> <p>Be aware of more serious signs of an <a href="https://www.allergy.org.au/patients/about-allergy/anaphylaxis">allergic reaction</a>. If in addition to red bumps and itchiness, other symptoms such as shortness of breath, cough, wheeze, chest tightness or facial swellings develop while sitting on the grass, people may need urgent medical care.<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/243046/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/deryn-lee-thompson-1449312">Deryn Lee Thompson</a>, Lecturer in Nursing, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Why sending a belated gift is not as bad as you probably think − and late is better than never

More than half of Americans say <a href="https://www.lendingtree.com/credit-cards/study/holiday-gift-stressors/">that gift-giving stresses them out</a>.</p> <p>Concerns about on-time delivery are so common that people share holiday <a href="https://www.goodmorningamerica.com/living/story/christmas-shipping-deadlines-2024-74159960">deadlines for each shipping service</a>. And in the event that you can’t meet these deadlines, there are now handy <a href="https://www.washingtonpost.com/lifestyle/home/package-delays-christmas-gifts-etiquette/2020/12/23/578a369e-43a5-11eb-b0e4-0f182923a025_story.html">etiquette guides</a> offering advice for how to inform the recipient.</p> <p>If you’ve sent late gifts thanks to <a href="https://www.washingtonpost.com/business/2020/12/15/postal-service-holiday-packages-delays/">shipping delays</a>, <a href="https://nymag.com/strategist/article/top-gifts-to-buy-before-they-sell-out-2022.html">depleted stocks</a> or even good old-fashioned <a href="https://wwd.com/feature/last-minute-holiday-shopping-survey-reveal-curious-consumer-trends-1234684998/">procrastination</a>, our new research may offer some welcome news.</p> <p>In a series of studies that will soon be published in the Journal of Consumer Psychology, we found that people overestimate the negative consequences of sending a late gift.</p> <h2>Trying to follow norms</h2> <p>Why do people tend to overestimate these consequences? Our findings indicate that when people give presents, they pay more attention <a href="https://doi.org/10.1002/jcpy.1318">to norms about gifting</a> than the recipients do.</p> <p>For example, other researchers have found that people tend to be reluctant to give <a href="https://doi.org/10.1348/014466604X23428">used products as presents</a> because there’s a norm that gifts should be new. In reality, though, many people are often open to receiving used stuff.</p> <p>We found that this mismatch also applies to beliefs about the importance of timing. Many people worry that a late gift will signal that they don’t care about the recipient. They then fear their relationship will suffer.</p> <p>In reality, though, these fears are largely unfounded. Gift recipients are much less worried about when the gift arrives.</p> <p>Unfortunately, aside from causing unnecessary worry, being overly sensitive about giving a late present can also influence the gift you choose to buy.</p> <h2>Compensating for lateness</h2> <p>To test how lateness concerns affect gift choice, we conducted an online study before Mother’s Day in 2021. We had 201 adults participate in a raffle. They could choose to send their mother either a cheaper gift basket that would arrive in time for the occasion or a more expensive one that would arrive late.</p> <p>Concerns about lateness led nearly 70% of the participants to choose the less expensive and more prompt option.</p> <p>In another study, we conducted the same kind of raffle for Father’s Day and got similar results.</p> <p>Aside from finding that people will choose inferior items to ensure speedier delivery, we also found that givers may feel that they can compensate for lateness with effort.</p> <p>In another online study of 805 adults, we discovered that participants were less likely to expect a late delivery to damage a relationship if they signaled their care for the recipient in a different way. For example, they believed that putting an item together by hand, versus purchasing it preassembled, could compensate for a present being belated.</p> <h2>Better late than never?</h2> <p>If sending something late isn’t as bad as expected, you may wonder whether it’s OK to simply not send anything at all.</p> <p>We’d caution against going that route.</p> <p>In another online study of 903 participants, we found that recipients believed that not receiving anything at all was more likely to harm a relationship than receiving something as much as two months late.</p> <p>That is, late is better than never as far as those receiving gifts are concerned.</p> <p>You may want to keep that in mind, even if that new <a href="https://www.theguardian.com/lifeandstyle/2021/dec/19/game-over-why-santa-may-struggle-to-bring-you-that-ps5-xbox-or-ipad">gaming console</a>, <a href="https://variety.com/2020/biz/news/baby-yoda-animatronic-toy-sold-out-hasbro-1203510368/">action figure</a> or <a href="https://www.usatoday.com/story/tech/2019/12/24/oculus-quest-headsets-sold-out-into-february/2742443001/">virtual reality headset</a> is sold out this holiday season.

A brief history of Christmas Pudding – and why it can actually be quite good for you

<p><em><a href="https://theconversation.com/profiles/hazel-flight-536221">Hazel Flight</a>, <a href="https://theconversation.com/institutions/edge-hill-university-1356">Edge Hill University</a></em></p> <p>Even in these hard and strange times, Christmas will be celebrated and traditions upheld. And for many British households, Christmas dinner would not be complete without a Christmas pudding – traditionally served with brandy sauce, brandy butter or custard.</p> <p>The Christmas pudding originated in the <a href="http://medievalcookery.com/recipes/frumenty.html">14th-century</a> as a sort of porridge, originally known as “<a href="http://cookit.e2bn.org/historycookbook/1116-frumenty.html">frumenty</a>”, which bears little resemblance to the dessert we know today.</p> <p>It was <a href="https://historydollop.com/2020/03/15/frumenty-a-medieval-wheat-porridge/">originally made</a> with hulled wheat, boiled in milk, seasoned with cinnamon and coloured with saffron. It was associated with meatless days, lent and advent and was often served as a plain dish. But there are a <a href="https://www.epersianfood.com/frumenty/">variety of recipes</a> which included <a href="https://www.mumwhatelse.com/christmas-pudding-traditional-recipe/s">additions</a> such as beef, mutton, raisins, currants, prunes, wines and spices.</p> <p>In some instances, this was the staple food for Christmas eve, although in Yorkshire it was eaten first thing <a href="https://www.gutenberg.org/files/19098/19098-h/19098-h.htm">on Christmas morning</a>. In the 17th-century changes to the recipe were made. It was thickened with eggs, breadcrumbs, dried fruit and beer or spirits were added – and came to resemble something a bit more like a sweet pudding. However, it was the Victorians who fine tuned the recipe into the <a href="http://www.bbc.co.uk/shropshire/content/articles/2005/12/07/christmas_pudding_recipe_feature.shtml#:%7E:text=Brandy%20Sauce&amp;text=This%20stew%20was%20served%20as,to%20give%20the%20pudding%20richness">Christmas pudding</a> many of us enjoy today.</p> <p>A Christmas pudding should have 13 ingredients – that represent Jesus and the 12 disciples. Traditionally, these ingredients include: raisins, currants, suet, brown sugar, breadcrumbs, citron, lemon peel, orange peel, flour, mixed spices, eggs, milk and brandy. Brandy is also <a href="https://www.pudforallseasons.com.au/blog/christmas-pudding-history-and-traditions">traditionally</a> poured over the pudding and set alight. The flaming brandy is said to represent the passion of Christ.</p> <p>Christmas puddings were traditionally boiled in a “pudding cloth”, although today are usually steamed in a bowl. Presented on the table with a sprig of holly, they are then doused in brandy and set alight.</p> <p>The last Sunday before Advent became known as “<a href="https://www.goodhousekeeping.com/uk/christmas/christmas-countdown/a550045/ultimate-stir-up-sunday-when/">stir up Sunday</a>”. This was when the ingredients of the pudding would be assembled and stirred up in a bowl with a wooden spoon (representing the manger) from east to west – symbolising the journey taken by the three wise men. Traditionally, every family member stirs the pudding three times and makes a secret wish.</p> <p>Trinkets were always included in the traditional pudding. As a child I still remember the excitement of waiting to see who was going to <a href="https://metro.co.uk/2016/12/16/why-do-people-put-money-in-christmas-puddings-6327772/">find the sixpence</a>. Whoever found the coin was believed to have good fortune over the coming year.</p> <h2>A healthy pud?</h2> <p>Although the Christmas holidays can sometimes feel a little unhealthy – with a lot of sitting around and excessive food consumption – the ingredients that makeup a Christmas pudding are actually <a href="https://www.express.co.uk/life-style/health/365596/Why-Christmas-pudding-is-good-for-you">pretty nutritious</a>.</p> <p>Traditional Christmas puddings consists of fibre rich ingredients, such as fruits, nuts and currants. Dried fruits are rich in fibre, enzymes, polyphenols (substances with a <a href="https://www.ijmrhs.com/medical-research/dry-fruits-and-diabetes-mellitus.pdf">high antioxidant activity</a>), vitamins and minerals. <a href="https://www.bbc.co.uk/food/recipes/christmaspudding_71054">Sultanas, currants, apricots</a> and <a href="https://www.goodhousekeeping.com/uk/food/recipes/a557006/pear-and-ginger-pudding">pears</a> are highly nutritious and packed with <a href="https://www.webmd.com/diet/foods-rich-in-potassium">essential potassium and iron</a>. And although dried fruits can contain a lot of sugar, they have a lower glycemic index value so don’t impact your blood sugar in the same way as other sweet treats.</p> <p>Raisins are also rich in antimicrobial compounds, fibre and iron. These compounds lower the risk of heart disease and can relieve constipation. Prunes too can also aid with digestion, relieve constipation, reduce inflammation and protect cells from free radical damage.</p> <p>Walnuts, hazelnuts, pecans and almonds can also be added into the mix and these all come with a range of <a href="https://www.healthline.com/nutrition/benefits-of-walnuts">health benefits</a> – from <a href="https://www.nhs.uk/news/food-and-diet/nuts-may-lower-cholesterol/">lowering cholesterol levels</a> and reducing heart disease risk to delivering high levels of vitamin E, polyphenols and melatonin.</p> <p>The mixed spices, cinnamon, ginger, cloves, pimentos (or all spice) in a Christmas pudding are also an incredible source of <a href="https://food.ndtv.com/food-drinks/health-benefits-of-38-important-spices-from-around-the-world-1811783">aromatic antioxidants</a>. Spices aid digestion and have anti-inflammatory and anti-bacterial properties. They can supposedly even help to reduce bloating, cramps and nausea – key if you’ve been overdoing it a bit.</p> <p>There is one secret ingredient often overlooked but included in many recipes – <a href="https://www.lovefood.com/recipes/56899/christmas-pudding-recipe">the carrot</a>. Rich in beta-carotene, which the body utilises to produce Vitamin A, carrots are good for lowering cholesterol levels and, yes, for the health of your eyes.</p> <h2>A global tradition</h2> <p>Although a British tradition, the Christmas pudding is eaten in various countries including <a href="https://theconversation.com/how-christmas-pudding-evolved-with-australia-35027#:%7E:text=The%20Christmas%20pudding%20was%20there,usual%20rations%20at%20Christmas%20time">Australia</a> and <a href="https://www.foodandhome.co.za/recipes/karoo-steamed-christmas-pudding">South Africa</a>. The Canadians also have a version which includes <a href="https://cannedpeachesproject.com/canadian-christmas-pudding-recipe/">potatoes alongside the carrots</a>.</p> <p>The Christmas pudding even makes its way into literature, with Charles Dickens’ Christmas Carol making <a href="https://www.inliterature.net/food-in-literature/baked-goods/cakes/2012/12/a-christmas-carol-steamed-christmas-pudding.html">reference to it</a>. Then there is the case for Agatha Christie’s Hercule Poirot to solve in which he is advised to avoid the <a href="https://www.agathachristie.com/stories/the-adventure-of-the-christmas-pudding">plum pudding</a> – another name for the Christmas pud.</p> <figure><iframe src="https://www.youtube.com/embed/IFKJJVzRvGI?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>One well known fact about the Christmas pudding is that there always seems to be some left over after Christmas day. In fact Christmas puddings of the past could last up to a year, so it was often shared out. Indeed, in 1885 a British newspaper reported the joyful consumption of a <a href="http://www.chinovalleyaz.net/DocumentCenter/View/5620/December-2019-Senior-Sentinel">plum pudding</a> – sent overland via special envoy from Tehran — to a group of British soldiers stationed in northwestern Afghanistan.</p> <p>If you don’t fancy posting a pudding there are a number of ways you can share and use the <a href="https://www.bbcgoodfood.com/howto/guide/10-ways-leftover-christmas-desserts">leftovers</a> – with a whole host of recipes from Christmas strudel to a black pudding breakfast replacement.

Pilot explains why plane windows are rounded

<p dir="ltr">A pilot has revealed why plane windows are the unique shape that we see today, sharing a glimpse into the world of airplane design and engineering. </p> <p dir="ltr">American Airlines pilot Captain Steve, who regularly makes TikTok videos on the marvel of flying, shared the reason why plane windows today are slightly rounded instead of square, revealing why this design became the norm. </p> <p dir="ltr">"Some of the airliners were designed with square windows and over in Europe as airplanes started to climb higher and require more pressurisation, they discovered a problem," he shared in a clip that has since been viewed over two million times.</p> <p dir="ltr">Following a series of inflight disasters caused by their rectangular counterparts, the window designs had to be changed, as Captain Steve said, “The airplanes literally came apart.”</p> <p dir="ltr">He added that "they lost a few airplanes in midair" because the square windows created "a hairline crack" right in the edge, and the stress on the airframe caused by the pressurisation was simply too much.</p> <p dir="ltr">As a result, engineers decided to round the windows' frames so they wouldn't break under the strain and they've "never had a problem since," according to the pilot.</p> <p dir="ltr">The video was flooded with comments by curious passengers, with one person writing, “I have never thought about this but it makes so much sense!

Forget Bob Geldof: this is why you don’t like Mondays

Grouchy even? Difficulties getting out of bed? Mondayitis can happen to the best of us. But rest assured: it’s a phenomenon science can actually explain.</p> <p>In fact, there are a range of explanations: perhaps you hate your job and/or are bullied at work; or maybe you <a href="http://www.youtube.com/watch?v=wmin5WkOuPw">live it large at the weekends</a> and come down with a crash on Mondays.</p> <p>But perhaps the most common cause involves our body clock – i.e. our circadian rhythms – and how our weekend sleeping habits throw our normal rhythms out of whack.</p> <h2>Blue Monday</h2> <p>As Sally Ferguson of the University of South Australia explained in <a href="https://theconversation.com/keeping-time-how-our-circadian-rhythms-drive-us-17">a recent article for The Conversation</a>, your circadian rhythm is your “natural pacemaker”. It controls a range of bodily cycles including the 24-hour cycle that regulates your degree of alertness at various times of day.</p> <p>Normally, our rhythm helps sustain our wakefulness until the end of the day and sustain our sleep until we’re ready to arise in the morning.</p> <figure class="align-center "><img src="https://images.theconversation.com/files/1062/original/mondayitis.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/1062/original/mondayitis.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=291&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/1062/original/mondayitis.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=291&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/1062/original/mondayitis.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=291&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/1062/original/mondayitis.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=365&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/1062/original/mondayitis.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=365&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/1062/original/mondayitis.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=365&amp;fit=crop&amp;dpr=3 2262w" alt="" /><figcaption><span class="caption">Image courtesy of Leon Lack.</span></figcaption></figure> <p>The above image shows how the normally-timed circadian “bed” (approximately 11pm to 7am) is surrounded by periods of low sleepiness (or alertness): this is also known as the “sleep forbidden zone” and the “wake-up zone”.</p> <p>In both, your body “wants” you to be awake: in the “sleep forbidden zone” you’ll find it hard to get to sleep, and in the “wake-up zone”, your body will “try” to wake you up.</p> <p>If the timing of your body clock changes – by partying till the wee hours, for example – these two zones can shift, making it harder to get to sleep at certain hours.</p> <p>In practice, this means that if you stay up a couple of hours later than normal one night, the “sleep forbidden zone” will drift to between 8pm and midnight, making it very difficult to get to sleep until after midnight.</p> <p>If this drifting occurs when it is necessary to get up early – e.g. on weekdays – you’ll lose sleep and be tired the next day.</p> <p>If this happens most days of the week, you’ll build up a sleep debt over the week that you will probably want to “pay off” when you have the opportunity to do so – on the weekend for most of us.</p> <h2>Sleep-in, and pay the price</h2> <p>How do you catch up on sleep on the weekend? You could go to bed earlier on Friday or Saturday night or you could sleep in later on Saturday and Sunday mornings. Ah, the luxury of the weekend sleep-in! Isn’t that what weekends are for?</p> <p>Unfortunately, though, that long-awaited weekend lie-in can cause problems come Monday.</p> <p>By sleeping in, you actively delay your body clock <em>again</em>, which can make it hard to get to sleep on Sunday night and leave you not feeling properly awake until later on Monday morning.</p> <h2>I don’t like Mondays (tell me why!)</h2> <p>Thanks to your weekend lie-in(s), your circadian rhythms have drifted away from their normal position and so, when that alarm clock starts bleating, you’re still at your lowest body temperature (see image above).</p> <p>You are expected to be up and out into the world while still in your “circadian bed”.</p> <p>Sure, you’ll probably feel better by noon with the help of the circadian “wake-up zone” (and maybe a stiff coffee or two) but the bad start to Monday has put you behind and you spend the rest of the week in catch-up mode.</p> <p>This vicious cycle is a problem for many, particularly <a href="http://en.wikipedia.org/wiki/Night_owl_(person)">“night owls”</a> whose rhythms are delayed even more than normal.</p> <p>So what can be done?</p> <p>Minimising the number of late bedtimes you have is a good start, as this will reduce your need for catch-up sleep.</p> <p>And if you do need to have catch-up sleep on the weekend, don’t sleep in late: get up about the same time you normally would and, if you need it, have a siesta instead.</p> <p>You’ll feel better for it come Monday morning.</p> <p><em><a href="https://theconversation.com/profiles/leon-lack-1142">Leon Lack</a>, Professor of Psychology, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

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

<p><em><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></em></p> <p>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.</p> <p>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.</p> <p>Hangover anxiety can make even simple tasks feel overwhelming. Here’s why it happens, and what you can do about it.</p> <h2>What does alcohol do to our brains?</h2> <p>A hangover is the body’s way of recovering after drinking alcohol, bringing with it a range of symptoms.</p> <p><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.</p> <p>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.</p> <p>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.</p> <p>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.</p> <p>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.</p> <h2>Genes play a role</h2> <p>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.</p> <p>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.”</p> <h2>Do you remember what you said last night?</h2> <p>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>.</p> <p>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.</p> <p><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.</p> <p>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.</p> <h2>Preventing hangover anxiety</h2> <p>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.</p> <p>Generally, the more you drink, the more intense your hangover symptoms might be, and the worse you are likely to feel.</p> <p>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>.</p> <p>If you do wake up feeling anxious:</p> <ul> <li> <p>focus on the physical recovery to help ease the mental strain</p> </li> <li> <p>drink plenty of water, eat a light meal and allow yourself time to rest</p> </li> <li> <p>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</p> </li> <li> <p>consider journalling. This can help re-frame anxious thoughts, put your feelings into perspective and encourage self-compassion</p> </li> <li> <p>talk to a close friend. This can provide a safe space to express concerns and feel less isolated.</p> </li> </ul> <p>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" /></p> <p><em><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></em></p> <p><em>Image credits: Shutterstock</em></p> <p><em>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?

<p><em><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></em></p> <p>Are you one of these people who loathes spending time outdoors at dusk as the weather warms and mosquitoes start biting?</p> <p>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.</p> <p>So why does our body react and itch after being bitten by a mosquito? And why are some people more affected than others?</p> <h2>What happens when a mosquito bites?</h2> <p>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>.</p> <p>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.</p> <p><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.</p> <p>Once the mosquito has made its way to your skin, things get a little gross.</p> <p>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.</p> <p>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.</p> <p>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.</p> <p>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.</p> <h2>Are some people allergic to mosquito spit?</h2> <p>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.</p> <p>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.</p> <p>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>.</p> <p>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.</p> <p>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.</p> <p>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.</p> <h2>How best to treat the bites?</h2> <p>Research into treating bites <a href="https://linkinghub.elsevier.com/retrieve/pii/S0161589023002304">has yet to provide</a> a single easy solution.</p> <p>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.</p> <p>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.</p> <p>There is some evidence that <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC10309056/">heat may alleviate</a> some of the discomfort.</p> <p>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.</p> <p>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.</p> <h2>To save the scratching, stop the bites</h2> <p>Of course, it’s better not to be bitten by mosquitoes in the first place.
