How do mosquito repellents work? A chemistry expert explains

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/daniel-eldridge-1494633">Daniel Eldridge</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a> It’s summertime, and for many of us that means plenty of time outside – and, unfortunately, mosquitoes. The combination of the <a href="https://theconversation.com/why-your-summer-might-be-full-of-mosquitoes-according-to-a-scientist-98369">increase in temperature and plenty of water</a> is ideal for these blood-sucking insects to make their presence felt. In the best-case scenario, they are a pest, delivering a highly unpleasant sting. At the other end of the spectrum, they are vectors for diseases responsible for <a href="https://www.cdc.gov/global-health/impact/fighting-the-worlds-deadliest-animal.html">more human fatalities than any other animal on Earth</a>. To keep them at bay, many of us will reach for the bottle of insect repellent or citronella candles in order to avoid the bite and incessant itching that comes with it. But how do these repellents actually work? <h2>A complex interplay</h2> <a href="https://www.mcgill.ca/oss/article/health-technology/why-mosquitos-bite-you-and-how-make-them-stop">A great deal</a> of research has gone into understanding how and why female mosquitoes – they are the ones that bite us – are attracted to people. There is evidence showing they are attracted to the <a href="https://www.nih.gov/news-events/nih-research-matters/how-mosquitoes-detect-people">carbon dioxide</a> we exhale, lactic acid found in our sweat, and a variety of other <a href="https://pubmed.ncbi.nlm.nih.gov/24315103/">skin odours</a> and <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6482070/">volatile compounds</a> we give off. The interplay between all these factors is quite <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC8906108/">complex</a>. To ward off mosquitoes, physical barriers such as netting make for the best protection. However, while you might put netting around a backdoor patio and barbecue, doing this for any large space is simply not practical. This is where repellents come in. <h2>DEETerrent</h2> There are a variety of mosquito repellents available. The most tried-and-true products are based on a substance called N,N-diethyl-meta-toluamide, more commonly referred to as DEET. This molecule has been commercially available since 1957, <a href="https://www.usda.gov/media/blog/2018/05/17/protecting-military-flying-foes">after the United States military discovered</a> it was an effective insect repellent. DEET is often used as a <a href="https://www.consumerreports.org/health/insect-repellent/how-safe-is-deet-insect-repellent-safety-a4952100929/">point of comparison</a> for <a href="https://www.nejm.org/doi/full/10.1056/NEJMoa011699">studies</a> investigating alternatives. <a href="https://scijournals.onlinelibrary.wiley.com/doi/full/10.1002/ps.5476?casa_token=prUg_pX7fjAAAAAA%3AuEKT5PGXWU1mO4fakwQ9NSEY-0uVYBEz25zWxXjMOp5AxX5UFWENJc1UF_JdsKA45x3sSHpmJSLJSwM">Studies show that</a>, provided they are used according to direction, <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4041896/">DEET products are safe and effective</a>. For example, it is recommended that when required, <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9458079/">sunscreen is applied</a> before the repellent. DEET products are not recommended for infants. The exact mechanism by which DEET repels mosquitoes and other insects is <a href="https://www.tandfonline.com/doi/full/10.1080/19336934.2015.1079360#d1e132">still explored</a> <a href="https://link.springer.com/article/10.1007/s13258-020-00991-z">today</a>. Many studies link its success to mosquitoes having receptors that sense the presence of DEET, deterring them from closely approaching our skin. Some investigations suggest that when DEET is detected, it <a href="https://pubmed.ncbi.nlm.nih.gov/18339904/">inhibits mosquitoes’ attraction</a> to us, while others show evidence that mosquitoes “<a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC2518096/pdf/zpq13598.pdf">smell and avoid</a>” DEET. There are also numerous reports demonstrating mosquitoes don’t bite when they <a href="https://www.cell.com/current-biology/pdfExtended/S0960-9822(19)30402-6">land on</a> DEET-treated skin. This is because DEET acts as a contact-based repellent and conveys a chemical message to mosquitoes to leave. <a href="https://www.tandfonline.com/doi/full/10.1080/19336934.2015.1079360">Studies</a> <a href="https://www.cell.com/current-biology/pdfExtended/S0960-9822(19)30402-6">suggest</a> that DEET likely works through a combination of the processes described here. <h2>Effective alternatives</h2> Another more recent family of mosquito repellent products rely on an active ingredient called picaridin (or icaridin). The current consensus is that picaridin products are safe, and highly effective. For many, they are considered appealing as they <a href="https://www.sciencedirect.com/science/article/pii/S0190962207014673?casa_token=zzPMhkW9QtIAAAAA:Euk6hjWnuiem6OAq020Xv0Pu70K7LfN_siLGcK1DIyOZn-mbH7U9tKK115rAK0rYbWQ2oaMGfg#bib49">don’t have as strong a scent</a> as DEET. Picaridin products have been reported to be <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4270489/">equally effective</a> as DEET, or in some cases, even <a href="https://academic.oup.com/jtm/article/25/suppl_1/S10/4990399">slightly superior</a>, though the outcome depends on their concentration too. The other repellent regularly reported as being effective is para-menthane-3,8-diol (PMD). This is produced by chemical treatment of <a href="https://www.phrp.com.au/issues/december-2016-volume-26-issue-5/a-review-of-recommendations-on-the-safe-and-effective-use-of-topical-mosquito-repellents/">oil of lemon eucalyptus</a>. Untreated, this oil isn’t effective at repelling mosquitoes. However, <a href="https://onlinelibrary.wiley.com/doi/10.1002/(SICI)1099-1573(199606)10:4%3C313::AID-PTR854%3E3.0.CO;2-O">several</a> <a href="https://journals.sagepub.com/doi/full/10.1016/j.wem.2015.11.007">studies</a> have shown that PMD is an effective mosquito repellent. The ability of these repellents to deter mosquitoes is <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4270489/">dose</a> <a href="https://academic.oup.com/jtm/article/25/suppl_1/S10/4990399">dependent</a>. In all cases, it’s important that an appropriate dose is applied, with re-application sometimes required to keep protection to a maximum. The performance of these products varies according to many other variables too, including <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4270489/">the species of mosquito</a>. <h2>What about citronella?</h2> Citronella products, including candles and topical formulations, are popular choices for keeping mosquitoes away. However, in systematic testing, these <a href="https://onlinelibrary.wiley.com/doi/10.1155/2015/361021">have been shown</a> to be <a href="https://www.nejm.org/doi/full/10.1056/NEJMoa011699">far less effective</a> than DEET. Studies have also shown that <a href="https://academic.oup.com/jinsectscience/article/17/1/24/2996380?login=false">citronella candles don’t</a> <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4617422/">fend off mosquitoes</a> <a href="https://pubmed.ncbi.nlm.nih.gov/8827606/">as much</a> as you might like. There are many other repellent products on the market. Given the widespread interest in preventing mosquito bites, natural remedies abound. It’s important to recognise that natural <a href="https://academic.oup.com/jinsectscience/article/17/1/24/2996380?login=false">isn’t necessarily more effective</a> and it <a href="https://theconversation.com/what-does-a-chemical-do-addressing-misconceptions-about-chemistry-104085">isn’t necessarily safer</a>. In <a href="https://www.nejm.org/doi/full/10.1056/NEJMoa011699">most reported studies</a>, DEET and picaridin are reported as having the greatest duration of protection (of the order of hours) and greatest effect on the mosquitoes. They are more thoroughly tested than many alternatives. When others are tested, they are often found wanting. One study described sound-based devices as being the repellent equivalent of <a href="https://academic.oup.com/jinsectscience/article/17/1/24/2996380?login=false">snake oil</a>. And although repellent bracelets contain working ingredients, they are largely ineffective in that form. This is because of insufficient concentrations of the active ingredient being “emitted”. When it comes to preventing disease transmission via mosquitoes, the <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4041896/">benefits</a> of the proven repellents far outweigh the risks.<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/244403/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/daniel-eldridge-1494633">Daniel Eldridge</a>, Senior Lecturer in Chemistry, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

How can I keep my cat happy? 5 tips from a vet to help your feline friend live their best life

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/anne-quain-12802">Anne Quain</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> Around <a href="https://animalmedicinesaustralia.org.au/report/pets-in-australia-a-national-survey-of-pets-and-people-2/">one third of Australian households live with at least one cat</a>, yet surveys tell us the cats’ <a href="https://journals.sagepub.com/doi/10.1177/1098612X19890189">needs are not being met</a>. Cats may <a href="https://www.sup.org/books/media-studies/unified-theory-cats-internet">rule the internet</a>, but humans often misconstrue feline behaviour. Earlier this year, the Washington Post boldly declared <a href="https://www.washingtonpost.com/home/2024/03/12/cats-behavior-misunderstood/">cat’s arent jerks – they’re just misunderstood</a>. This was prompted by research showing that, contrary to unhelpful stereotypes, <a href="https://www.sciencedirect.com/science/article/pii/S1090023323000795">cats are not antisocial</a>. They can and do bond closely with humans. The more we learn about cats, the more we realise they are complex individuals with unique <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC8300181/">personalities</a> and preferences, capable of <a href="https://www.nature.com/articles/s41598-024-74006-2">learning</a>. From understanding your cat’s language to keeping them safe and healthy – here are science-backed tips to improve the lives of your feline flatmates. <h2>1. Pay attention to body language</h2> Cats communicate with humans using body language and vocalisation. However, while cats direct meows at humans, and the meows vary depending on the context, humans <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC7765146/">are not great at decoding them</a>. But we can read cat body language. For example, slow blinking is likely to indicate a <a href="https://www.nature.com/articles/s41598-020-73426-0">positive emotional state</a>. Cats who are not happy (for example, don’t want to be touched) will freeze, move away, flatten their ears, hiss, or – if they feel they have no other option – scratch or bite. It is better to allow cats to approach you on their terms, rather than pushing for social interaction. A cat approaching you with their tail up is giving a <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC8469685/">friendly signal</a>, while a tail swishing from side to side signals annoyance. Cats should always have the option to opt out of any interaction, like being touched. If you aren’t sure, just “<a href="https://www.companionanimalpsychology.com/p/purr-science-of-making-your-cat-happy.html">ask</a>”: stop patting them. If they walk away, they’re not keen. If they rub their head against you, they want to continue the interaction. <h2>2. Provide a healthy environment</h2> The American Association of Feline Practitioners and the International Society of Feline Medicine have agreed upon <a href="https://journals.sagepub.com/doi/full/10.1177/1098612X13477537">five pillars of a healthy feline environment</a>: <ol> <li> A safe space so that cats can retreat if frightened. </li> <li> Multiple, separated key resources (food, water, toileting areas, scratching areas, play areas and resting or sleeping areas) so that cats can comfortably conduct their daily activities. </li> <li> Opportunity for play and predatory behaviour, such as games with wand toys that simulate hunting. </li> <li> Positive, consistent and predictable human-cat interactions, respecting a cat’s choice about whether and how they interact. </li> <li> Respecting the importance of a cat’s senses by avoiding undesirable stimuli (strong smells and loud noises), and providing desirable sensory stimulation (for example, use of <a href="https://theconversation.com/are-catnip-and-treats-like-it-safe-for-cats-heres-how-they-affect-their-minds-and-moods-214947">catnip or silver vine</a>). </li> </ol> These pillars provide a useful checklist. If you read this and realise your cat’s food and water are right next to the litter tray, you can improve your cat’s environment (and their experiences of eating and toileting) by separating these resources right now. <h2>3. Clean the litter tray!</h2> A litter tray may represent an unpleasant chore to you, but the importance of a spacious litter tray to your cat cannot be overstated. Cats <a href="https://www.sciencedirect.com/science/article/pii/S0376635716302972">prefer using a clean litter tray</a>, even if they are the only cat in the household. Cats like to <a href="https://www.sciencedirect.com/science/article/pii/S016815911730151X">spend time in the tray</a> before, during and after toileting, and they generally <a href="https://www.sciencedirect.com/science/article/pii/S1558787814000033">prefer a large tray</a>. Poor litter hygiene is associated with a risk of urinary problems, which can be <a href="https://onlinelibrary.wiley.com/doi/10.1111/jvim.16389">life-threatening</a>. A <a href="https://doi.org/10.1177/1098612X19890189">survey of over 12,000 Australian cat owners</a> found that urinary problems were more common in households with a low number of litter trays per cat, less frequent removal of faeces from the trays, and the use of crystal-type cat litter. If you switch the type of litter you provide, a <a href="https://www.mdpi.com/2076-2615/12/8/946">slow transition</a> is recommended to allow cats to get used to the change. <h2>4. Read the room</h2> Do you have more than one cat? Tension between household cats is common but often overlooked, as it’s not always physical fighting. Signs of inter-cat tension can include prolonged staring, or even blocking the use of resources such as the litter tray or cat door, to prevent other cats from using them. In their <a href="https://journals.sagepub.com/doi/10.1177/1098612X241263465">2024 intercat-tension guidelines</a>, the American Association of Feline Practitioners note this can case chronic fear, anxiety and stress-related illnesses in cats. Learning to recognise and manage tension between household cats can improve the welfare of all parties. When you love your cat, it is tempting to seek to amplify the joy by adopting another. But many cats prefer to be the only cat in the household, and don’t cope well with a <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC10083434/">feline flatmate</a>. If they have positive interactions with familiar, trusted humans, they’re unlikely to be lonely. <h2>5. Keep cats and other animals safe</h2> Historically, domesticated cats earned their keep <a href="https://www.sciencedirect.com/science/article/pii/S0169534720300100">protecting grain stores</a> from rodents. But what constitutes responsible cat ownership has changed. Around 65% of Australia’s cat owners <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC10215893/">confine their cats</a> indoors always, while 24% keep their cats confined at night. A major driver for indoor-only housing of cats is their <a href="https://theconversation.com/one-cat-one-year-110-native-animals-lock-up-your-pet-its-a-killing-machine-138412">predation of wildlife</a>. Another is concerns about roaming-associated risks to cats, including cat fights, infectious diseases (such as <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9546031/">feline immunodeficiency virus or FIV</a>), misadventure and motor vehicle trauma. But owners of cats kept entirely indoors were more likely to report <a href="https://www.sciencedirect.com/science/article/abs/pii/S0168159119301054?via%3Dihub">“problem” behaviours</a>. Ideally, cats shouldn’t be allowed to free-roam unsupervised where they can harm wildlife, even within the bounds of the property where you live. More than a third of local councils in Australia <a href="https://www.abc.net.au/news/2024-05-19/banning-pet-cats-roaming-native-animals-billions-dollars-council/103856000">now require</a> cats to be contained overnight or 24 hours a day. Outdoor access provides sensory stimulation, with different sights, sounds and smells. Alternatives to free roaming include providing access to a well-designed cat run, harness-training your cat, or supervising your cat. Cats who don’t leave home unless they’re moving house or being taken to the vet, quickly learn to associate the cat carrier with a trip to an unfamiliar environment. It doesn’t take a genius to work out that a vet visit is imminent when the carrier comes out. But that negative association can be changed. <a href="https://www.sciencedirect.com/science/article/pii/S0168159118302703">Cats who were rewarded with treats</a> when they approached, stepped inside or rested in the carrier for six weeks were much less stressed during veterinary visits. Cats are intelligent, and contrary to popular opinion, can be trained. The process can be enriching for cats and humans alike. With patience and commitment, <a href="http://www.smallanimaltalk.com/2017/04/book-review-trainable-cat-plus-that.html">you can train your cat</a> – from a simple “sit” to voluntarily stepping into the cat carrier. In short, give cats choice, respect their “cat-ness”, pay attention to their needs and try to see our world from their point of view. Your cat will be happier for it.<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/242774/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/anne-quain-12802">Anne Quain</a>, Senior Lecturer, Sydney School of Veterinary Science, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Expert reveals how to cope with flight anxiety

While thousands of Aussies travel by plane everyday, not everyone is so relaxed about air travel. According to recent Google data, searches for advice on flight anxiety are on the rise by more than 5000 per cent. Thankfully, there is help out there for those who struggle with anxious thoughts around flying. Researcher and neuroscientist Dr Brian Ramos from <a href="https://simplynootropics.com.au" target="_blank" rel="noopener">Simply Nootropics</a> explained why some people are impacted more than others. "People's past experiences, personality traits, and levels of general anxiety all play a role in how intensely they experience flying anxiety, making some individuals more prone to it than others," he told <a href="https://travel.nine.com.au/latest/how-to-get-over-flight-anxiety-before-holiday-expert-tips/72ff01bd-8245-4ba9-a440-8a5fa6fa74db">9Travel</a>. He went on to offer four ways to combat flight anxiety on your next trip. Reframe your anxiety as excitement Dr Ramos believes that by redefining the physical signs of anxiety as excitement for your holiday, you can fool your brain into thinking differently. "Reframing anxiety as excitement can trick your brain into receiving your nervous system's response more positively," Brian said. "Both anxiety and excitement trigger similar physical responses, like a racing heart and butterflies, but the key difference lies in how we interpret them.” "Instead of viewing these sensations as signs of danger, you can remind yourself they signal anticipation and energy." Think about the facts Looking at your situation practically can help calm your anxious mind when on a plane, according to Dr Ramos. "Look around you - is anyone else freaking out? Aeroplanes are one of the safest modes of transportation," Brian said. "Statistically, the odds of an accident are extremely low, with air travel being far safer than driving in a car - something we all do regularly and don't bat an eyelid at." Keep yourself busy By tapping into mindful activities can help push anxious thoughts to the back of your mind. As Brian says, "Distracting your mind with a good podcast or book is a great way to manage flight anxiety by redirecting your focus away from fear-inducing thoughts." "Engaging with a story or interesting conversation can keep your brain occupied.” Re-centre your brain if you feel yourself spiralling "To calm an anxiety attack during a flight, first, focus on your breathing," Brian said. "Practice deep, slow breaths; inhaling through your nose for four counts, holding for four, and exhaling through your mouth for four.” "Second, ground yourself using the 5-4-3-2-1 technique: identify five things you can see, four you can touch, three you can hear, two you can smell, and one you can taste.” "Finally, use positive self-talk."

Few Australians know the second verse of our national anthem – or how out of date it is

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/wendy-hargreaves-1373285">Wendy Hargreaves</a>, <a href="https://theconversation.com/institutions/university-of-southern-queensland-1069">University of Southern Queensland</a> There are two verses to Advance Australia Fair, but do you know the second? Probably not. It’s in our citizenship booklet, <a href="https://immi.homeaffairs.gov.au/citizenship/test-and-interview/our-common-bond">Our Common Bond</a>, suggesting Aussies know it and new citizens could be questioned on it in their citizenship test. Yet <a href="https://www.pmc.gov.au/honours-and-symbols/australian-national-symbols/australian-national-anthem/australian-national-anthem-use-and-protocol">official protocol</a> makes singing it optional. And who’ll choose to sing both verses when thousands of sporting fans just want the game to start? There are living generations who never properly learnt Advance Australia Fair. Before 1984, <a href="https://theconversation.com/50-years-on-advance-australia-fair-no-longer-reflects-the-values-of-many-what-could-replace-it-226737">most school students</a> sang God Save the Queen. Schools today teach verse one, but whether we learn verse two is haphazard. If school students sing along to a pre-recorded accompaniment with two verses, we’ll learn verse two. If we sing along with a squeaking school beginner band, one verse is probably all we’ll endure. I suspect if we knew the second verse our common bond would be arguing about it. Australians <a href="https://theconversation.com/outrage-over-schoolgirl-refusing-to-stand-for-anthem-shows-rise-of-aggressive-nationalism-103160">acted passionately</a> when debating one word in verse one, yet verse two barely raises an eyebrow. It’s the controversy we need to have (after we’ve googled the lyrics). <h2>The birth of our second verse</h2> The problem with verse two comes from its origins. It wasn’t in Peter Dodds McCormick’s original 1878 composition. His <a href="https://trove.nla.gov.au/newspaper/article/62087415">second verse</a> championed gallant Cook sailing with British courage to raise old England’s flag, proving “Britannia rules the waves”. His third and fourth verses weren’t any more appropriate. So, before Advance Australia Fair became our anthem in 1984, the National Australia Day Council made shrewd edits. Instead of using verse two from McCormick’s original version, they turned to <a href="https://nla.gov.au/nla.obj-165919018/view?partId=nla.obj-165919026">another version of Advance Australia Fair</a> written for federation in 1901. The federation version introduced a new commemorative verse, the only other verse the council kept: <blockquote> Beneath our radiant Southern Cross we’ll toil with hearts and hands To make our youthful Commonwealth renowned of all the lands For loyal sons beyond the seas we’ve boundless plains to share With courage let us all combine to Advance Australia Fair. </blockquote> Next, the council fixed the gendered language in the federation verse. “Loyal sons” became “those who’ve come”. They deleted “youthful” with an uncanny premonition that age would become sensitive. (For verse one, Australians resolved the debate ingeniously in 2021 <a href="https://www.theguardian.com/australia-news/2020/dec/31/we-are-one-and-free-australian-anthem-to-change-in-attempt-to-recognise-indigenous-history">by replacing</a> “young and free” with “one and free”.) But that’s all the council changed in verse two. They endorsed the rest. <h2>What’s wrong with verse two?</h2> The federation verse, understandably, celebrated the politics of 1901. The lyrics begin mildly but repetitively, “Beneath our radiant Southern Cross we’ll toil with hearts and hands”. I’m not sure why we’re toiling in both verses. Perhaps Aussies have an exceptional work ethic. In the next line, the word “commonwealth” was included to mark federation. The forming of the Commonwealth of Australia in 1901 marked a transition from six British colonies (New South Wales, Victoria, Tasmania, South Australia, Western Australia and Queensland) into one nation. On one hand, it celebrates unity and cooperation between colonies. But by singing the intended meaning of the verse, that the nation began when the colonies united, we disrespect the knowledge Australia already was many nations of First Peoples. <figure class="align-right zoomable"><a href="https://images.theconversation.com/files/643701/original/file-20250121-15-cbyhoq.png?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/643701/original/file-20250121-15-cbyhoq.png?ixlib=rb-4.1.0&q=45&auto=format&w=237&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/643701/original/file-20250121-15-cbyhoq.png?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=806&fit=crop&dpr=1 600w, https://images.theconversation.com/files/643701/original/file-20250121-15-cbyhoq.png?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=806&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/643701/original/file-20250121-15-cbyhoq.png?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=806&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/643701/original/file-20250121-15-cbyhoq.png?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=1013&fit=crop&dpr=1 754w, https://images.theconversation.com/files/643701/original/file-20250121-15-cbyhoq.png?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=1013&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/643701/original/file-20250121-15-cbyhoq.png?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=1013&fit=crop&dpr=3 2262w" alt="Illustration: White Australia - the great national policy song" /></a><figcaption>The federation verse says Australia has ‘boundless plains to share’ – but many were excluded from this vision of Australia. <a class="source" href="https://commons.wikimedia.org/wiki/File:White_Australia_-_the_great_national_policy_song_.webp">Wikimedia Commons</a>, <a class="license" href="http://creativecommons.org/licenses/by-sa/4.0/">CC BY-SA</a></figcaption></figure> The second questionable lyric in verse two is “for those who’ve come across the seas, we’ve boundless plains to share”. In 1901, Australia’s idea of sharing land was specific. We recruited enthusiastically for more British immigration, yet rejected migrants who weren’t white. <a href="https://www.naa.gov.au/explore-collection/immigration-and-citizenship/immigration-restriction-act-1901">The Immigration Restriction Act 1901</a>, one of our parliament’s first laws, allowed immigration officers to set near impossible dictation tests in any European language. In effect, this meant anyone could be excluded from immigrating by what would be known as the White Australia Policy. Australia’s 21st century approach to sharing with foreigners also draws media attention. The breach of human rights at <a href="https://theconversation.com/the-un-says-australia-violated-human-rights-law-but-its-unlikely-to-change-the-way-we-treat-refugees-247096">detention centres</a> and the limiting of <a href="https://theconversation.com/international-student-numbers-in-australia-will-be-controlled-by-a-new-informal-cap-heres-how-it-will-work-246318">international student visas</a> to stem migration suggest we have “bounds” after all. <h2>The way forward</h2> If the federation verse is theoretically testable for new citizens, then we should check if the values of 1901 and 2025 still match. Without checking, Australia is stagnating, not advancing. The way forward is in the last line of verse two: “With courage let us all combine to Advance Australia Fair”. In 1901, that was a plea for spirit and cooperation between colonies when forming a national parliament. Yet, there’s a timeless truth in those words. By debating our anthem courageously, we can be united by challenge, enriched by diversity and ingenious at rewriting lyrics.<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/246678/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/wendy-hargreaves-1373285">Wendy Hargreaves</a>, Senior Learning Advisor, <a href="https://theconversation.com/institutions/university-of-southern-queensland-1069">University of Southern Queensland</a> Image credits: Izhar KHAN/Shutterstock Editorial This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

What are plyometric exercises? How all that hopping and jumping builds strength, speed and power

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/justin-keogh-129041">Justin Keogh</a>, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> and <a href="https://theconversation.com/profiles/mandy-hagstrom-1180806">Mandy Hagstrom</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> If you’ve ever seen people at the gym or the park jumping, hopping or hurling weighted balls to the ground, chances are they were doing plyometric exercises. Examples include: <ul> <li><a href="https://www.youtube.com/watch?v=DEwh2mRg3EU&t=315s">box jumps</a>, where you repeatedly leap quickly on and off a box</li> <li><a href="https://www.youtube.com/watch?v=gS4F_YrwZVs">lateral skater hops</a>, where you bound from side to side like a speeding ice skater</li> <li>rapidly throwing a heavy <a href="https://www.youtube.com/watch?v=2iGj4gdfv4E&t=175s">medicine ball against a wall</a>, or to the ground</li> <li>single leg hops, which may involve hopping on the spot or through an obstacle course</li> <li>squat jumps, where you repeatedly squat and then launch yourself into the air.</li> </ul> There are many <a href="https://us.humankinetics.com/products/training-for-speed-agility-and-quickness-3rd-edition-with-hkpropel-online-video?srsltid=AfmBOor2XNPNu3WtrytuxooFb_HmqXf6kEYwlBILhmEiMO2O1uOTIj81">more examples</a> of <a href="https://us.humankinetics.com/products/plyometrics-pdf">plyometric exercises</a>. What ties all these moves together is that they use what’s known as the “<a href="https://www.frontiersin.org/research-topics/10437/the-stretch-shortening-cycle-of-active-muscle-and-muscle-tendon-complex-what-why-and-how-it-increases-muscle-performance/magazine">stretch shortening cycle</a>”. This is where your muscles rapidly stretch and then contract. <h2>Potential benefits</h2> Research shows incorporating plyometric exercise into your routine can help you: <ul> <li><a href="https://www.frontiersin.org/journals/physiology/articles/10.3389/fphys.2024.1302610/full">jump higher</a></li> <li><a href="https://pubmed.ncbi.nlm.nih.gov/22450257/">sprint faster</a></li> <li>reduce the chances of getting a serious sporting injuries such as anterior cruciate ligament <a href="https://pubmed.ncbi.nlm.nih.gov/36244964/">(ACL) tears</a></li> <li>build <a href="https://pubmed.ncbi.nlm.nih.gov/19897415/">muscle strength</a></li> <li>improve <a href="https://pubmed.ncbi.nlm.nih.gov/38305252/">bone mineral density</a> (especially when combined with <a href="https://pubmed.ncbi.nlm.nih.gov/33357834/">resistance training</a> such as weight lifting), which is particularly important for women and older people at risk of falls.</li> </ul> Studies have found plyometric exercises can help: <ul> <li><a href="https://pubmed.ncbi.nlm.nih.gov/30387072/">older people</a> who want to retain and build muscle strength, boost bone health, improve posture and reduce the risk of falls</li> <li>adolescent athletes who want to build the <a href="https://pubmed.ncbi.nlm.nih.gov/36767213/">explosive strength</a> needed to excel in sports such as athletics, tennis, soccer, basketball and football</li> <li><a href="https://pubmed.ncbi.nlm.nih.gov/27704484/">female athletes</a> who want to jump higher or change direction quickly (a useful skill in many sports)</li> <li><a href="https://pubmed.ncbi.nlm.nih.gov/33956587/">endurance runners</a> who want to boost physical fitness, run time and athletic performance.</li> </ul> And when it comes to plyometric exercises, you get out what you put in. Research has found the benefits of plyometrics are significantly greater when every jump was performed with <a href="https://pubmed.ncbi.nlm.nih.gov/30741877/">maximum effort</a>. <h2>Potential risks</h2> All exercise comes with risk (as does not doing enough exercise!) Plyometrics are high-intensity activities that require the body to absorb a lot of impact when landing on the ground or catching medicine balls. That means there is some risk of musculoskeletal injury, particularly if the combination of intensity, frequency and volume is too high. You might miss a landing and fall, land in a weird way and crunch your ankle, or get a muscle tear if you’re overdoing it. The National Strength and Conditioning Association, a US educational nonprofit that uses research to support coaches and athletes, <a href="https://www.nsca.com/store/product-detail/BOOK/2275/9781718210868">recommends</a>: <ul> <li>a maximum of one to three plyometric sessions per week</li> <li>five to ten repetitions per set and</li> <li>rest periods of one to three minutes between sets to ensure complete muscle recovery.One <a href="https://pubmed.ncbi.nlm.nih.gov/30387072/">meta-analysis</a>, where researchers looked at many studies, found plyometric training was feasible and safe, and could improve older people’s performance, function and health.</li> </ul> Overall, with appropriate programming and supervision, plyometric exercise can be a safe and effective way to boost your health and athletic performance.<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/246322/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/justin-keogh-129041">Justin Keogh</a>, Associate Dean of Research, Faculty of Health Sciences and Medicine, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> and <a href="https://theconversation.com/profiles/mandy-hagstrom-1180806">Mandy Hagstrom</a>, Senior Lecturer, Exercise Physiology.

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

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/louise-baur-5284">Louise Baur</a>, <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.

Brown</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> 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. 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. 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. 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. <h2>What’s wrong with BMI?</h2> 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. 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. 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. 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. 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. On the other hand, others who aren’t athletes but have excess fat may have a high BMI but no associated health problems. BMI is therefore an imperfect tool to help us diagnose obesity. <h2>What is the new definition?</h2> The goal of the <a href="https://pubmed.ncbi.nlm.nih.gov/36878238">Lancet Diabetes & 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. 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. We define two categories of obesity based on objective signs and symptoms of poor health due to excess body fat. 1. Clinical obesity 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). There are 18 diagnostic criteria for clinical obesity in adults and 13 in children and adolescents. These include: <ul> <li> breathlessness caused by the effect of obesity on the lungs </li> <li> obesity-induced heart failure </li> <li> raised blood pressure </li> <li> fatty liver disease </li> <li> abnormalities in bones and joints that limit movement in children. </li> </ul> 2. Pre-clinical obesity A person with pre-clinical obesity has high levels of body fat that are not causing any illness. 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. However, people with pre-clinical obesity are generally at higher risk of developing diseases such as heart disease, some cancers and type 2 diabetes. <h2>What does this mean for obesity treatment?</h2> Clinical obesity is a disease requiring access to effective health care. 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. <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: <ul> <li> 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 </li> <li> 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 </li> <li> 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. </li> </ul> <h2>Should pre-clinical obesity be treated?</h2> For those with pre-clinical obesity, health care should be about risk-reduction and prevention of health problems related to obesity. This may require health counselling, including support for health behaviour change, and monitoring over time. 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. 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. <h2>What happens next?</h2> 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. Once adopted, training health professionals and health service managers, and educating the general public, will be vital. 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. 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" /> <a href="https://theconversation.com/profiles/louise-baur-5284">Louise Baur</a>, 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.

Travelling in 2025? Here’s how to become a ‘regenerative’ tourist

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/veselina-stoyanova-2260559">Veselina Stoyanova</a>, <a href="https://theconversation.com/institutions/university-of-birmingham-1138">University of Birmingham</a> At the start of a new year, many of us contemplate resolutions aimed at self-improvement and a better lifestyle. It is also a time when many of us start thinking about holidays. But have you considered combining the two? Could 2025 be the year when you resolve to be a better traveller? For in 2024, many tourists were on the receiving end of a very loud and very clear message. In some of Europe’s most popular holiday destinations, including Barcelona and Mallorca, there were <a href="https://edition.cnn.com/2024/07/27/travel/why-europe-has-become-an-epicenter-for-anti-tourism-protests-this-summer/index.html">large protests</a> against the negative effects of mass tourism. Overcrowding, <a href="https://www.sciencedirect.com/science/article/abs/pii/S0160738319300817?via%3Dihub">environmental damage</a>, <a href="https://www.sciencedirect.com/science/article/pii/S0160738321001420?via%3Dihub">unaffordable housing</a> and cultural erosion appear to have pushed communities to their limits. There are <a href="https://www.bbc.com/travel/article/20240925-the-summer-that-tourism-fell-apart">vocal demands</a> to make tourism <a href="https://www.sciencedirect.com/science/article/pii/S0160738322001621#s0045">more sustainable</a>. So, perhaps it’s time for travellers to <a href="https://www.unwto.org/tourism-data/un-tourism-tourism-dashboard">shift towards</a> a more sensitive and responsible form of travel. <a href="https://www.tandfonline.com/doi/full/10.1080/14616688.2022.2044376#abstract">“Regenerative” tourism</a>, for example, aims to enhance the wellbeing of places and the people who live in them. Unlike mass tourism, which often strains resources and compromises residents’ <a href="https://www.tandfonline.com/doi/full/10.1080/21568316.2019.1599604">quality of life</a>, regenerative tourism is about giving back – by supporting local economies, preserving cultures and nurturing the environment. This means treating your holiday as more than a personal escape. Instead of just lying on a sun lounger, consider planting trees in a reforestation project or learning traditional crafts from local artisans and participating in cultural events. Depending on the location, there might be chances to join in <a href="https://www.volunteerworld.com/en/volunteer-abroad/voluntourism">community programmes</a> which help alleviate poverty or improve the lives of Indigenous communities. These actions can empower locals and help create a more inclusive environment. Wherever you go, you can seek out experiences which help to <a href="https://sdgs.un.org/goals">restore and sustain</a> the places you visit. Imagine, for instance, learning traditional Venetian glassblowing techniques as a way of supporting the artisans who keep this ancient craft alive in Italy. In rural Spain, you could support local communities in remote villages by staying in family-run guesthouses. Or in Bulgaria, you could join farm-to-table dining experiences and visit organic farms in the Thracian Valley to help promote local food production and <a href="https://www.un.org/sustainabledevelopment/hunger/">food security</a>. There may be local events or workshops you can join, cooking classes you can take, or cultural festivals where you can interact with residents and appreciate their perspective. All of these – and countless other examples – are opportunities for travellers to make a contribution to the places they visit, leaving a positive impact. They also offer the traveller the chance to make personal connections and unforgettable memories – providing moments to engage directly with locals people, to ask questions and learn about local culture and history and community activities. Being a gracious guest promotes goodwill and strengthens the bond between travellers and locals. <h2>Direction of travel</h2> These connections also make holidays not merely about personal enjoyment, but about something deeper, with a positive affect on the places we visit. So as you browse the idyllic destinations you might decide to travel to in 2025, it’s worth asking yourself whether you want to be a passive tourist, or a regenerative traveller who combines a sense of curiosity with a sense of responsibility. Tourism in 2025 will be a big part of <a href="https://www.sciencedirect.com/science/article/abs/pii/S2211973617300922">many countries’ economies</a>, but not everyone is happy with the industry and its impact on the world. Yet, consumers can change its direction. The choices we make about our travel plans could mean the difference between a holiday that contributes to a legacy of positive change or one that perpetuates the social and environmental issues facing the planet and its people. As we look ahead, the question is not just where to travel on holiday, but how to travel. Perhaps 2025 could be the year that your adventures inspire transformation, creating a sustainable and inclusive future for tourism.

Nine reporter stood down over controversial $50k gift

Today show presenter Alex Cullen has been stood down after accepting a huge cash prize from The Block billionaire Adrian Portelli. Portelli, known for his attention-grabbing <a href="https://www.oversixty.com.au/finance/money-banking/the-block-billionaire-s-generous-christmas-stunt" target="_blank" rel="noopener">antics</a>, recently announced that he was sick of his nickname "Lambo guy", which had stuck after turned up to a 2022 auction of The Block in a yellow Lamborghini. The billionaire put a call out to the media saying that he would give $50,000 to the first journalist or presenter to publicly call him by his new preferred nickname "McLaren Man." Cullen dropped the nickname on-air during a Today show cross from the Australian Open on Friday morning, even sharing footage of the moment on his Instagram account afterwards, tagging Portelli in the post. “We have a winner! Well played sir,” Portelli wrote in an Instagram story, sharing a screenshot of a bank transfer. Cullen's employer, Channel Nine, said that the presenter had agreed to step down on Saturday while the network looked into the payment. “Nine is taking this matter extremely seriously,” a Nine spokesperson told news.com.au. “Appropriate action has been promptly taken, including arranging for the funds to be returned. “While we review the circumstances in which this occurred, Alex has agreed to stand down.” Accepting cash, gifts or benefits to undermine journalistic independence, and inappropriately using a journalistic position for personal gain, are both breaches to the Media Entertainment and Arts Alliance (MEAA) Journalist Code of Ethics. It was created by journalists in 1944 to promote basic values for the Australian media industry. As news of the controversy spread, Portelli took to Instagram to speak out against journalists who still refer to him as "Lambo guy". “I wanted to show the media that I do have a large platform as well, and I’m not afraid to use it. Maybe be a bit more respectful, and I’ll respect you guys as well,” he said in a video posted on Saturday night. Image: Nine/ Instagram

Even calm people can fly into a rage behind the wheel. Here’s how to curb your road rage – before it’s too late

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/milad-haghani-1454675">Milad Haghani</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> If someone bumps into us on the footpath or in the mall, we’re generally quite forgiving. We instinctively apologise or step aside, and usually don’t scream at, stalk, or attack the other person. But put us in a car, and <a href="https://x.com/Boenau/status/1755234912540459059">something changes</a>. People who appear calm in everyday life suddenly tailgate, honk, or shout at strangers. <a href="https://www.sciencedirect.com/science/article/pii/S0925753524002467?casa_token=76NSmREtG8MAAAAA:yFEcndOLjARRfthZMFwOQ3UmPeqgJEwSuAvkaA51rH8fA7v8RzHDamohBhf8Ai7jb3Nrp98pz4I">Problems at work</a> or home can suddenly explode in the form of righteous anger toward other road users. Road rage <a href="https://www.sciencedirect.com/science/article/pii/S0001457523000192">increases crash risk</a>, and victims of road rage incidents often have <a href="https://www.mynrma.com.au/media/press-releases/2024/nrma-releases-worrying-road-rage-data">children in the car</a> with them. So, why does driving <a href="https://www.sciencedirect.com/science/article/pii/S0022437524000914?dgcid=raven_sd_recommender_email">bring out the worst in us</a>? And more importantly, <a href="https://www.sciencedirect.com/science/article/pii/S0001457521001755?dgcid=raven_sd_recommender_email">what can we do about it</a>? <h2>Road rage remains common</h2> <a href="https://www.mynrma.com.au/media/press-releases/2024/nrma-releases-worrying-road-rage-data">Recent</a> <a href="https://www.budgetdirect.com.au/car-insurance/research/road-rage-study.html?utm_source=chatgpt.com">surveys</a> indicate road rage remains common in Australia. In September 2024, insurer NRMA <a href="https://www.mynrma.com.au/media/press-releases/2024/nrma-releases-worrying-road-rage-data">reported</a> a survey of 1,464 of its members in two states found many had witnessed road rage incidents such as: <ul> <li>tailgating (71%)</li> <li>drivers beeping other drivers (67%)</li> <li>drivers gesturing angrily at other drivers (60%)</li> <li>drivers deliberately cutting in front of other vehicles (58%)</li> <li>drivers getting out of their car to confront to confront another driver (14%)</li> <li>stalking (10%)</li> <li>physical assault (4%).</li> </ul> Another insurer, Budget Direct, <a href="https://www.budgetdirect.com.au/car-insurance/research/road-rage-study.html">reported</a> last year on a survey of 825 people that found about 83% had experienced shouting, cursing, or rude gestures from other people on the road (up by 18% since 2021). And of the female respondents, 87% reported they’d copped this kind of behaviour from other road users. Common triggers for driver anger include tailgating, perceived rudeness (such as not giving a “thank you” wave), and witnessing another person driving dangerously. Aggressive driving behaviours tend to be more common in <a href="https://search.informit.org/doi/abs/10.3316/informit.031918298391749">younger, male drivers</a>. Road rage is a global problem, with studies finding road rage remains common in places such as <a href="https://www.sciencedirect.com/science/article/pii/S0001457509002012?casa_token=G4nhNdF3olAAAAAA:8tdP0GyMiwN4_n4fekvQB-EiUSLa8Q2sgbpMhfUNWh0w9YqeiWft1aPY2ZSFLngcSFZAHfMOQhA">Japan</a>, the <a href="https://newsroom.aaa.com/2016/07/nearly-80-percent-of-drivers-express-significant-anger-aggression-or-road-rage/">US</a>, <a href="https://www.sciencedirect.com/science/article/abs/pii/S1369847805000884">New Zealand</a> and the <a href="https://www.sciencedirect.com/science/article/abs/pii/S1369847898000096">UK</a>, but the degree varies significantly from country to country. <h2>Who is more likely to fly into a rage on the road?</h2> Some of us are more likely than others to fly into a rage while driving. One way researchers <a href="https://www.sciencedirect.com/science/article/pii/S1369847815001722">measure</a> this is via a testing tool known as the <a href="https://www.yorku.ca/rokada/psyctest/driving.pdf">Driving Anger Scale</a>. Data from many studies using this test show drivers who are more prone to anger in general are <a href="https://research.monash.edu/en/publications/driving-anger-as-a-psychological-construct-twenty-years-of-resear">more likely to turn that anger into aggression</a>. They get annoyed by more things, are quicker to act on their feelings, take more risks, and as a result, are more likely to be involved in anger-related crashes. Research suggests that while female drivers experience anger just as much as male drivers, they are less likely to act on it in a <a href="https://www.turkpsikiyatri.com/PDF/C18S3/en/angerExpression.pdf">negative way</a>. Female drivers tend to feel more intense anger in certain situations, such as when <a href="https://www.sciencedirect.com/science/article/pii/S1369847815001722#f0010">faced with hostile gestures or traffic obstructions</a>, compared to their male counterparts. <h2>What can I do to reduce my road rage?</h2> In a car, we’re physically separated from others, which creates a sense of distance and anonymity – two factors that lower our usual social filters. Encounters feel fleeting. There’s a good chance you won’t be held accountable for what you or say or do, compared to if you were outside the car. And yet, we perceive the stakes as high because mistakes or bad decisions on the road can have serious consequences. This mix of isolation, stress, and the illusion of being in a bubble is a perfect recipe for heightened frustration and anger. <a href="https://www.sciencedirect.com/science/article/abs/pii/S0001457521001755?dgcid=raven_sd_recommender_email">Research</a> suggests techniques drawn from cognitive behavioural therapy may help. These include learning to identify when you are starting to feel angry, trying to find alternative explanations for other people’s behaviour, using mindfulness and <a href="https://www.sciencedirect.com/science/article/pii/S1369847815001758">relaxation</a> and trying to move away from the trigger. The American Automobile Association also <a href="https://exchange.aaa.com/wp-content/uploads/2013/06/Road-Rage-Brochure.pdf">suggests</a> you can reduce road rage incidents by being a more considerate driver yourself – always use your indicator, avoid cutting others off and maintain a safe distance from other cars. Try to stay calm when other drivers are angry, and allow extra time in your journey to reduce stress. If driving anger is a frequent issue, consider seeking support or <a href="https://www.healthdirect.gov.au/anger-management">anger management resources</a>. Avoiding — or at least being aware of — <a href="https://www.sciencedirect.com/science/article/pii/S1369847821002667">anger rumination</a> can make a big difference. This happens when someone replays anger-inducing events, like being cut off in traffic, over and over in their mind. Instead of letting it go, they dwell on it, fuelling their frustration and making it harder to stay calm. Recognising this pattern and shifting focus — like taking a deep breath or distracting yourself — can help stop anger from escalating into aggression. More broadly, public awareness campaigns highlighting the link between anger and risky driving could also encourage more drivers to seek help. The next time you get behind the wheel, try to remember the other driver, the cyclist, or pedestrian is just another person — someone you might pass on the street without a second thought. We’re often good at forgiving minor missteps in non-driving contexts. Let’s try to bring that same patience and understanding to the road.<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/244402/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/milad-haghani-1454675">Milad Haghani</a>, Senior Lecturer of Urban Risk & Resilience, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Most adults will gain half a kilo this year – and every year. Here’s how to stop ‘weight creep’

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/nick-fuller-219993">Nick Fuller</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> As we enter a new year armed with resolutions to improve our lives, there’s a good chance we’ll also be carrying something less helpful: extra kilos. At least half a kilogram, to be precise. “Weight creep” doesn’t have to be inevitable. Here’s what’s behind this sneaky annual occurrence and some practical steps to prevent it. <h2>Small gains add up</h2> Adults <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC3151731/">tend to gain weight</a> progressively as they age and typically gain an average of <a href="https://pubmed.ncbi.nlm.nih.gov/23638485/">0.5 to 1kg every year</a>. While this doesn’t seem like much each year, it amounts to 5kg over a decade. The slow-but-steady nature of weight creep is why many of us won’t notice the extra weight gained until we’re in our fifties. <h2>Why do we gain weight?</h2> Subtle, gradual lifestyle shifts as we progress through life and age-related biological changes cause us to gain weight. Our: <ul> <li> activity levels decline. Longer work hours and family commitments can see us become more sedentary and have less time for exercise, which means we burn fewer calories </li> <li> diets worsen. With frenetic work and family schedules, we sometimes turn to pre-packaged and fast foods. These processed and discretionary foods are loaded with hidden sugars, salts and unhealthy fats. A better financial position later in life can also <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/j.1467-789X.2011.00953.x">result in more dining out</a>, which is associated with a higher total energy intake </li> <li> sleep decreases. Busy lives and screen use can mean we don’t get enough sleep. This disturbs our body’s energy balance, increasing our <a href="https://www.sciencedirect.com/science/article/abs/pii/S1389945708700133">feelings of hunger</a>, triggering cravings and decreasing our energy </li> </ul> <ul> <li> stress increases. Financial, relationship and work-related stress increases our body’s production of cortisol, triggering food cravings and promoting fat storage </li> <li> metabolism slows. Around the age of 40, our muscle mass naturally declines, and our body fat starts increasing. Muscle mass helps determine our metabolic rate, so when our muscle mass decreases, our bodies start to burn fewer calories at rest. </li> </ul> We also <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2807660">tend to gain a small amount</a> of weight during festive periods – times filled with calorie-rich foods and drinks, when exercise and sleep are often overlooked. <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2807660">One study of Australian adults</a> found participants gained 0.5 kilograms on average over the Christmas/New Year period and an average of 0.25 kilograms around Easter. <h2>Why we need to prevent weight creep</h2> It’s important to prevent weight creep for two key reasons: 1. Weight creep resets our body’s set point Set-point theory suggests we each have a predetermined weight or set point. Our body works to <a href="https://theconversation.com/whats-the-weight-set-point-and-why-does-it-make-it-so-hard-to-keep-weight-off-195724">keep our weight around this set point</a>, adjusting our biological systems to regulate how much we eat, how we store fat and expend energy. When we gain weight, our set point resets to the new, higher weight. Our body adapts to protect this new weight, making it challenging to lose the weight we’ve gained. But it’s also possible to <a href="https://theconversation.com/whats-the-weight-set-point-and-why-does-it-make-it-so-hard-to-keep-weight-off-195724">lower your set point</a> if you lose weight gradually and with an interval weight loss approach. Specifically, losing weight in small manageable chunks you can sustain – periods of weight loss, followed by periods of weight maintenance, and so on, until you achieve your goal weight. 2. Weight creep can lead to obesity and health issues Undetected and unmanaged weight creep <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC5817436/">can result in</a> obesity which can increase our risk of heart disease, strokes, type 2 diabetes, osteoporosis and several types of cancers (including breast, colorectal, oesophageal, kidney, gallbladder, uterine, pancreatic and liver). A <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC5817436/">large study</a> examined the link between weight gain from early to middle adulthood and health outcomes later in life, following people for around 15 years. It found those who gained 2.5 to 10kg over this period had an increased incidence of type 2 diabetes, heart disease, strokes, obesity-related cancer and death compared to participants who had maintained a stable weight. Fortunately, there are steps we can take to build lasting habits that will make weight creep a thing of the past. <h2>7 practical steps to prevent weight creep</h2> 1. Eat from big to small Aim to consume most of your food earlier in the day and taper your meal sizes to ensure dinner is the smallest meal you eat. A low-calorie or small breakfast <a href="https://pubmed.ncbi.nlm.nih.gov/32073608/">leads to increased feelings of hunger</a>, specifically appetite for sweets, across the course of the day. We burn the calories from a meal <a href="https://pubmed.ncbi.nlm.nih.gov/32073608/">2.5 times more efficiently</a> in the morning than in the evening. So emphasising breakfast over dinner is also good for weight management. 2. Use chopsticks, a teaspoon or an oyster fork Sit at the table for dinner and use different utensils to encourage eating more slowly. This gives your brain time to recognise and adapt to signals from your stomach <a href="https://pubmed.ncbi.nlm.nih.gov/28718396/">telling you you’re full</a>. 3. Eat the full rainbow Fill your plate with vegetables and fruits of different colours first to support eating a high-fibre, nutrient-dense diet that will keep you feeling full and satisfied. Meals also need to be balanced and include a source of protein, wholegrain carbohydrates and healthy fat to meet our dietary needs – for example, eggs on wholegrain toast with avocado. 4. Reach for nature first Retrain your brain to rely on nature’s treats – fresh vegetables, fruit, honey, nuts and seeds. In their natural state, these foods release the same pleasure response in the brain as ultra-processed and fast foods, helping you avoid unnecessary calories, sugar, salt and unhealthy fats. 5. Choose to move Look for ways to incorporate incidental activity into your daily routine – such as taking the stairs instead of the lift – and <a href="https://theconversation.com/does-exercise-help-you-lose-weight-198292">boost your exercise</a> by challenging yourself to try a new activity. Just be sure to include variety, as doing the same activities every day often results in boredom and avoidance. 6. Prioritise sleep Set yourself a goal of getting a minimum of <a href="https://www.sciencedirect.com/science/article/abs/pii/S1389945708700133">seven hours of uninterrupted sleep</a> each night, and help yourself achieve it by <a href="https://www.nature.com/articles/ncomms3259">avoiding screens</a> for an hour or <a href="https://journals.sagepub.com/doi/abs/10.1177/1477153515584979?journalCode=lrtd">two</a> before bed. 7. Weigh yourself regularly Getting into the habit of weighing yourself weekly is a guaranteed way <a href="https://theconversation.com/how-often-should-you-really-weigh-yourself-223864">to help avoid the kilos creeping up</a> on us. Aim to weigh yourself on the same day, at the same time and in the same environment each week and use the best quality scales you can afford. <hr /> At the Boden Group, Charles Perkins Centre, we are studying the science of obesity and running clinical trials for weight loss. <a href="https://redcap.sydney.edu.au/surveys/?s=RKTXPPPHKY">You can register here</a> to express your interest.<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/244186/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/nick-fuller-219993">Nick Fuller</a>, Clinical Trials Director, Department of Endocrinology, RPA Hospital, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

There’s a link between walking speed and ageing well. Here’s how you can improve your pace

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/andres-rafales-perucha-1528635">Andrés Ráfales Perucha</a>, <a href="https://theconversation.com/institutions/universidad-san-jorge-5704">Universidad San Jorge</a> and <a href="https://theconversation.com/profiles/pablo-gargallo-aguaron-1528652">Pablo Gargallo Aguarón</a>, <a href="https://theconversation.com/institutions/universidad-san-jorge-5704">Universidad San Jorge</a> For decades, we have known that the way you walk, in particular your walking speed, is tied to your health. One study has even proposed that it be considered <a href="https://pubmed.ncbi.nlm.nih.gov/24812254/">a vital sign</a>, much like heart rate and blood pressure. <a href="https://pubmed.ncbi.nlm.nih.gov/26861693/">Various studies</a> have found a link between low walking speed in adults over 65 and a greater risk of cognitive impairment, cardiovascular disease, falls (which could lead to fractures), hospitalisation, and even an increased overall mortality rate. A higher walking speed, on the other hand, is associated with increased functional capacity, meaning a better ability to move around and do activities independently. It is also linked to <a href="https://www.thelancet.com/journals/lanhl/article/PIIS2666-7568(24)00092-8/fulltext">greater longevity</a>. But how fast should you walk? <a href="https://www.sciencedirect.com/science/article/abs/pii/S1568163714000646?dgcid=api_sd_search-api-endpoint">Studies</a> recommend a few simple tests, which principally consist of timing how long it takes a person to walk between two points at their usual pace. This <a href="https://www.physio-pedia.com/4_Metre_Walk_Test">test</a> is done over a distance of four metres. A speed of under 0.8 metres per second is associated with a greater risk of frailty. <h2>How to improve walking speed</h2> While there is slight disagreement as to the best exercise for increasing walking speed, the pattern that seems most effective is <a href="https://pubmed.ncbi.nlm.nih.gov/34409961/">multicomponent training</a>, which includes several different forms of exercise: <ol> <li> Balance exercises can help improve stability and prevent falls. Examples include walking in a straight line putting one foot in front of the other, or standing on one leg, alternating every 10-15 seconds. </li> <li> Flexibility exercises can improve mobility and reduce risk of injury. The benefits of movement in alleviating back pain are <a href="https://theconversation.com/back-pain-why-exercise-can-provide-relief-and-how-to-do-it-safely-162888">well documented</a>. </li> <li> Muscular exercises help build strength in the legs, buttocks and other body areas. These can be as straightforward as standing up and sitting down in a chair. </li> <li> Aerobic exercise improves stamina, and can include walking itself, or <a href="https://theconversation.com/seven-reasons-nordic-walking-is-better-for-you-than-the-normal-kind-187391">Nordic walking</a> (with hiking poles). </li> </ol> <h2>How much aerobic exercise do we need?</h2> The main <a href="https://www.who.int/publications/i/item/9789240014886">guides</a> on physical activity recommend that, provided they are physically and medically able, each adult should do at least 150 minutes of moderately intense aeoribic exercise per week. “Moderate” means you are not too out of breath to hold a conversation, but enough to notice an increased heart and breathing rate. There are few reasons not to do this kind of exercise, and it is beneficial for people with chronic illnesses, including cardiovascular issues, metabolic conditions, or even cancer. <h2>Muscle strength: How, and how much?</h2> Strengthening exercises have traditionally been recommended 2 to 3 times a week, with at least one set per exercise session of the main muscle groups: legs, buttocks, pectorals, back and arms. However, more recent studies suggest that doing less intense but more frequent strengthening exercises may be an effective way to <a href="https://pubmed.ncbi.nlm.nih.gov/34822137/">maintain muscle mass and strength</a>. This would mean doing them almost every day, including even small exercise “snacks” throughout the day. <h2>Use it or lose it</h2> If we don’t train them, muscle mass and strength decrease over time. This not only affects our mobility, but also increases the risk of health problems and even death. A little daily exercise can make a big difference. We therefore recommend that you try to maintain your physical condition as much as possible, both to improve your immediate health and prevent future problems. If you do not know where to start, the best option is always to consult a professional. If you have difficulties or limitations in exercising, a physiotherapist can help you to build a specialised exercise plan, or can adapt one to your needs.<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/245880/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/andres-rafales-perucha-1528635">Andrés Ráfales Perucha</a>, Fisioterapeuta y Personal Docente e Investigador de la Universidad San Jorge.

Aussie drivers urged to cash in on $140 million in unclaimed funds

The NSW government has urged Sydney motorists to access its toll road relief scheme, with $140 million left unclaimed since the cost-of-living support measure was introduced last year. Drivers who spend more than $60 in tolls weekly can claim the excess back under the "toll cap" introduced by the Minns government to help highly-tolled residents in Western Sydney. On Monday, Roads Minister John Graham said that while $75 million had already been paid to motorists, there's still $140 million yet to be claimed. “I want to remind motorists to get on to the Service NSW website and claim what they are entitled to in relief,” Graham said in a statement. Around 720,000 drivers are eligible for a slice of the payments. Over the past year, more than 276,000 claims were paid since the scheme was introduced, with an average claim of $277, according to the government. There were 115 suburbs where the average claim was $300 or more, including Parramatta, Lidcombe, Schofields, Westmead, Toongabbie, Merrylands and Auburn. “We know people are doing it tough and the toll cap is making it just that little bit fairer for drivers that heavily rely on the toll roads,” Graham said. He also added that reform talks with private toll road companies are still ongoing. In December, the government struck an in-principle deal with Transurban, a toll road operator, for a network-wide pricing system in attempt to ease the impact of toll payments on motorists. “The NSW government is progressing with toll reform to make tolls fairer overall,” Graham said on Monday.

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/ava-green-1396648">Ava Green</a>, <a href="https://theconversation.com/institutions/city-st-georges-university-of-london-1047">City St George's, University of London</a> The holiday season is here, and streets are filled with festive sparkles, twinkling lights and cheerful Christmas songs. While many of us are looking forward to spending the holiday period with family and friends, Christmas is anything but jolly for others. Some people are dreading to spend the period without loved ones. Others are fearful of spending it in the company of their extended family and relatives. Will your cousin provoke heated arguments at the dinner table again, outright bullying others and refusing to consider their perspective? Will your dad bring extravagant gifts and criticise others for their presents that he deems are inadequate? Will your aunt steal the show and make it all about her? Such behaviour <a href="https://journals.sagepub.com/doi/abs/10.1177/09637214211044109">is common in narcissism</a>, a personality trait which we all exhibit to various degrees. Narcissistic people have an <a href="https://theconversation.com/narcissism-why-its-less-obvious-in-women-than-in-men-but-can-be-just-as-dangerous-231392">insatiable need for attention</a> and validation. They feel entitled to special treatment, are unable to empathise with others, exploit people to boost their own self-esteem and display controlling and manipulative behaviour. It is not surprising, therefore, that many with narcissistic family members and relatives come to dread the holiday season. The good news, hopefully, is that this holiday season does not need to crash and burn into discord and frustration. Here’s how you can navigate these interactions while looking after yourself. <h2>Limit your exposure</h2> Not everyone has the ability to avoid difficult people, particularly if they are your own parents or siblings. If you can’t avoid your narcissistic relatives entirely, consider limiting the amount of time you spend with them. Imagine your sister ambushing you or creates a scene to draw attention to herself. Have a plan in place for gracefully exiting the conversation or the event itself if it becomes too emotionally draining. This could involve having a couple of emergency exits up your sleeve to avoid confrontation, such as “I am going to go and help mum and dad in the kitchen” or “I am going to go play with the kids”. Alternatively, you could be more straightforward, and comment that “I think I need some space, we can catch up later”. <h2>Set healthy boundaries</h2> A hallmark of narcissism is a <a href="https://www.sciencedirect.com/science/article/abs/pii/S0092656622001428">lack of empathy</a>. Because of their inability to empathise with others, narcissistic people will push boundaries and put their needs before yours. Having realistic expectations and planning accordingly can help ease feelings of frustration and disappointment. For instance, if you engage with your cousin during arguments, he will probably disregard your needs, perspective and feelings. He might make a comment that crosses the line. In any situation, set healthy boundaries by redirecting the conversation to neutralise a potential conflict. You could speak to his interests by asking questions such as “by the way, did you watch the latest episode of (his favourite show)” or “are you going to the football game next week (his favourite team)”? If that fails, set your boundaries firmly and concisely by saying “I do not want to talk about this right now”. <h2>Focus on what you can control</h2> Another hallmark of narcissism is poor emotional regulation – in other words, people with narcissistic traits may feel indignant to respond with <a href="https://psycnet.apa.org/buy/2014-57455-001">rage and aggression</a> if they feel mistreated or criticised. In these situations, they may <a href="https://link.springer.com/article/10.1007/s11199-024-01477-y">manipulate, bully and undermine others</a> to elevate themselves. Resist defensiveness and try to focus on what you can control: how you respond. If someone belittles you for a “mundane present” or for not having reached the same success in life as they think have, use the tactic of <a href="https://www.theguardian.com/science/2022/aug/31/grey-rocking-how-to-bore-a-toxic-narcissist-out-of-your-life">“grey rocking”</a> – being non-reactive, dull and uninteresting. This will avoid fuelling their need for attention. Remind yourself that their attack is not personal – this isn’t about you, it’s about their need for control. <h2>Reframe empathy</h2> If all else fails, you could try to manipulate a narcissistic relative into showing a bit of empathy. Research suggests that it may be possible to reframe empathy in <a href="https://link.springer.com/chapter/10.1007/978-3-319-92171-6_36">a way that makes it desirable</a> to narcissistic individuals. While this is more likely to work in the hands of a trained psychologist, and could backfire, it may be worth a try in a desperate situation. For example, you could quote facts or stories about how people who are good at taking the perspective of others are more successful as leaders than those who are not. Narcissistic people want to be seen to be good at everything, so if you make empathy look advantageous, they may be more likely to show it – or at least pretend to do so. <h2>Look after yourself</h2> While attempting all this, make sure you prioritise your mental and emotional wellbeing. It is okay to retreat to a quiet room to get some headspace or stepping outside for a walk. Remind yourself that you do not need to engage, interact or stay for the whole duration for the sake of family togetherness. Take time to relax in a space where you feel safe and create the time for things you enjoy, be it baking cookies, watching your favourite Christmas movie or wrapping gifts. Try to minimise one-to-one time with people who drain you and instead surround yourself with family members who are more understanding, empathetic and supportive. Whatever the power dynamics in your life might be, you can maintain your authenticity with grace and not only survive, but thrive, this holiday season.<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/245877/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/ava-green-1396648">Ava Green</a>, 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> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Festive bulge: scientists offer advice on how to beat overeating

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/thomas-c-erren-336309">Thomas C. Erren</a>, <a href="https://theconversation.com/institutions/university-of-cologne-2576">University of Cologne</a>; <a href="https://theconversation.com/profiles/philip-lewis-429997">Philip Lewis</a>, <a href="https://theconversation.com/institutions/university-of-cologne-2576">University of Cologne</a>, and <a href="https://theconversation.com/profiles/ursula-wild-1398207">Ursula Wild</a>, <a href="https://theconversation.com/institutions/university-of-cologne-2576">University of Cologne</a> Christmas and New Year are holidays with dietary excesses that many of us cannot control. This often leads to the “festive bulge”. As the holidays approach, could there be a recipe to contain this weight gain and pave the way to sustainable nutrition-based health at the same time? There’s a lot of focus on what we eat and how much we eat – but what about when we eat? Chrononutrition is the science of how timing affects our responses to nutrients. <a href="https://www.sciencedirect.com/science/article/pii/S0092867415003025?via%3Dihub">Scientific insights</a> into when we eat suggest it may be worth exploring for better health. While the idea of getting started on <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9370396/">chrononutrition over Christmas</a> can sound challenging, the guilty conscience that tends to follow feasting over the holidays may provide the needed motivation for the year ahead. So for better health in the new year, why not try out time-restricted eating (TRE)? TRE is a type of <a href="https://theconversation.com/is-intermittent-fasting-actually-good-for-weight-loss-heres-what-the-evidence-says-183500">intermittent fasting</a>: a person eats all their meals and snacks within a particular time window, ranging from six to 12 hours each day. This implies 12 to 18 hours of fasting. <a href="https://theconversation.com/is-body-weight-affected-by-when-you-eat-heres-what-science-knows-so-far-143303">More</a> and <a href="https://theconversation.com/delay-eating-breakfast-and-eat-dinner-early-if-you-want-to-lose-body-fat-new-study-101058">more research</a> suggests that this kind of timing may have a significant influence on our health via <a href="https://pubmed.ncbi.nlm.nih.gov/25404320/">interplays</a> between our <a href="https://pubmed.ncbi.nlm.nih.gov/25815987/">body clocks and nutrition</a>. As researchers with a focus on circadian biology, we have <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9370396/">identified the festive season</a> as a suitable starting point for a lifestyle change to time-restricted eating. <h2>What is chrononutrition?</h2> The basic idea of chrononutrition is that the body’s response to the timing of meals can promote well-being and health via the circadian timing system. This timing system refers to the internal 24-hour mechanism that primes our bodies for the challenges and stimuli of the 24-hour day. This includes when nutrients are likely to be consumed, how they are used within the body at a given time and how the body responds to them at a given time. A rodent experiment in the <a href="https://academic.oup.com/jn/article-abstract/10/1/63/4725662">1930s</a> led to a focus on counting calories and calorie-restricted eating. This dietary restriction extended the lifespan of rats in this case. It was subsequently shown in a wide range of species. The promise is large: if you eat less, then weight loss, better health and a longer life may follow. The rodent experiment was followed by research into diets that foster health and prevent disease. Interest in <a href="https://pubmed.ncbi.nlm.nih.gov/3794831/">“meal-timing, circadian rhythms and lifespan”</a> was sparked by Franz Halberg (known as the father of American chronobiology), among others, in the 1980s. These studies around food and behaviour take <a href="https://pubmed.ncbi.nlm.nih.gov/25404320/">evolutionary considerations</a> into account. For instance, rodents gain fitness when fed in a time-restricted manner. In contrast, human behaviour tends to involve more <a href="https://pubmed.ncbi.nlm.nih.gov/26411343/">erratic eating patterns</a> during the hours when people are awake. <h2>Lifestyle changes</h2> So what practical advice can we give on the occasion of Christmas and New Year from the <a href="https://www.nobelprize.org/prizes/medicine/2017/advanced-information/">2017 Nobel Prize-winning field of chronobiology</a>? The field gained recognition for its discoveries into how internal clocks organise our physiology and enable us to live in harmony with the external rhythms of day and night. Findings from this field point to a simple lifestyle change: limiting when you eat to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4255155/">eight to 10 hours</a> a day could protect you from developing obesity, or even lessen the negative health impacts of existing obesity. And time-restricted eating can work even if practised for only <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4255155/">five days per week</a>. Importantly, if you can reduce a long habitual eating window (for instance, 15 hours) to a time-restricted eating window of eight hours, you are likely to benefit more than someone who reduces a habitual eating window of 10 hours to eight hours. Reductions in eating-time windows have already <a href="https://www.nejm.org/doi/10.1056/NEJMoa2114833?url_ver=Z39.88-2003&rfr_id=ori:rid:crossref.org&rfr_dat=cr_pub%20%200pubmed">been found</a> to help some overweight humans lose weight, sleep better and feel more energised. Granted, much of the evidence comes from animal studies – and humans are certainly not big mice. Nonetheless, there have been no reports of detriments to this practice in humans. However, there has been <a href="https://www.sciencedirect.com/science/article/abs/pii/S0899900722001897?via%3Dihub">one report</a> of possible disadvantages to offspring in a pregnant animal model of time-restricted eating. <h2>Late breakfast and early supper</h2> Why not try what some studies suggest and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9370396/">start time-restricted eating over Christmas</a>, or put it on your New Year’s resolution list? To get started, consider having a late breakfast and an early dinner. Of course, if in doubt about the impact of time-restricted eating – or if you have medical or dietary restrictions, or are pregnant – talk to your doctors first for advice. Beyond paying attention to calorie intake and food composition, “when we eat” is a relatively simple and potentially sustainable approach.<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/195822/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/thomas-c-erren-336309">Thomas C.

How to turn your gift-giving crisis into a Christmas miracle

Christmas is coming, and with it, the annual What do I get everyone?! panic. Every year it’s the same: endless debates about whether Dad really needs another tie, your sister’s mysterious aversion to gift cards, and the horrifying memory of that one time you gave your neighbour a single fruitcake. Let’s be honest – nobody wants a single fruitcake. This year, skip the stress and let <a href="http://www.hamperworld.com.au/" target="_blank" rel="noopener">Hamper World</a> turn your gift-giving crisis into a Christmas miracle. Hamper World has been the secret Santa we all need for over 25 years, crafting stunning gift hampers packed with the best Australian-made goodies. We’re talking premium wines, gourmet snacks, fancy chocolates and artisanal treats that taste like they were made by elves with Michelin stars. It’s the kind of stuff that makes people’s eyes light up before they’ve even finished unwrapping it. <img src="https://oversixtydev.blob.core.windows.net/media/2024/12/IMG_0313_1280.jpg" alt="" width="1280" height="831" /> The beauty of these hampers is that they don’t just scream thoughtful gift. They also whisper, I didn’t just pick this up on the way here. Whether you’re shopping for family, friends, co-workers or that one random person who showed up for Christmas lunch (we all have one), there’s a hamper that’ll fit the bill – and make you look like a gifting genius in the process. Now, here’s the kicker: these hampers aren’t just packed with amazing stuff; they’re also doing some serious good. Every item is sourced from Australian producers, so your Christmas cheer is supporting local farmers, chocolatiers and small businesses. It’s basically like giving two gifts in one: one to your loved one, and one to Australia’s economy. Take that, Santa. <img src="https://oversixtydev.blob.core.windows.net/media/2024/12/21737A_1280_3.jpg" alt="" width="1280" height="720" /> And don’t get us started on delivery. You know that classic Christmas movie moment where the hero races through the snow (or, in our case, the scorching summer heat), trying to deliver the perfect gift? You don’t need that drama. Hamper World ships all over Australia, making sure your gift arrives looking as festive and fabulous as it did when it left. Whether it’s bound for a city penthouse or a bush retreat, your hamper will get there on time and looking sharp. But the real magic is in the presentation. Hamper World wraps these beauties up like they belong on the cover of a gourmet magazine. No need for awkward DIY attempts at gift wrapping that end with you covered in tape and regret. Just order, sit back and bask in the glory of being the best gift-giver in the history of your family. <img src="https://oversixtydev.blob.core.windows.net/media/2024/12/IMG_0321_1280.jpg" alt="" width="1280" height="831" /> Christmas hampers are also a great solution for those tricky situations. Got a boss who already has everything? Boom, corporate hamper. Want to thank your neighbours for putting up with your late-night karaoke sessions? Sweet treats hamper, done. And don’t forget to treat yourself – after all, nothing says Merry Christmas to me like a hamper full of wine and cheese. So, this Christmas, skip the socks, the scented candles and the questionable DIY projects. Head over to <a href="http://www.hamperworld.com.au" target="_blank" rel="noopener">www.hamperworld.com.au</a> or call 1800 566 433 and let Hamper World handle the heavy lifting. Because the only thing better than giving the perfect gift is doing it without breaking a sweat – and maybe even snagging a 10% gift card if you order early. Now that’s the holiday spirit.

When a casual punt turns into addictive gambling – how to ensure it won’t really cost you

Gambling is a real and growing problem. Left unchecked, the occasional punt can quickly develop into an addiction, with devastating effects on finances and relationships. Debts can spiral and the stress causes marriages to fail and other relationships to splinter. <a href="https://www.monash.edu/medicine/news/latest/2022-articles/gambling-and-homelessness-a-growing-problem-amongst-older-australians">Research published in 2022 by Monash University</a> also found that gambling and homelessness are “interconnected”, singling out senior Australians as most in the firing line. Before things devolve to that level, consider these steps for putting boundaries around your – or your partner’s – gambling. Remember: Big business is big for a reason In 2023, the <a href="https://www.aihw.gov.au/reports/australias-welfare/gambling">Australian Institute of Health and Welfare (AIHW)</a> noted that “Australians lose approximately $25 billion on legal forms of gambling each year, representing the largest per capita losses in the world”. That equates to every single Aussie losing $909 annually. The reality is these companies exist to make money – and skew the odds in their favour, not yours. Keep that in mind the next time you’re tempted to try your “luck”. Stay active For some people, especially retirees, gambling becomes something to pass the time and get them out of the house. However, you needn’t gamble your money away to keep boredom at bay. There are healthier and more productive ways to do this. For example, there are a myriad of social, sporting, and recreational groups for seniors and retirees. A lack of work commitments offers the flexibility to indulge in travel, both within Australia and overseas. Take the opportunity to socialise with friends and family. Turn your hobby or side hustle into a proper business. Or get a dog you can take for long walks. The possibilities are endless… Don’t punt with what you can’t afford to lose Gambling with a bit of money you have specifically put aside for leisure activities is one thing; gambling your life savings or money needed for essentials like food, bills and keeping a roof over your head is quite another. Having lost that essential money, problem gamblers often become desperate to try and win it back – begging, borrowing or even stealing more, with the repercussions quickly spiralling out of control as that money is often lost too. If you must gamble, only gamble what you can afford to lose: have a budgeted amount and stick to it no matter what. Anyone who deep-down knows they aren’t disciplined with their money would be wise to think twice altogether. Never borrow to gamble As a rule of thumb, money that comes with a cost attached to it should only ever be spent on things that will make more money in the long run, like buying a home or investing. When it comes to gambling, always use your free cash. Money you have borrowed, redrawn from your home loan, or racked up on your credit card will have to be repaid eventually – with interest on top. Choose a place and a time “Most people using gambling machines are older Australians,” <a href="https://www.monash.edu/medicine/news/latest/2022-articles/gambling-and-homelessness-a-growing-problem-amongst-older-australians">Monash University’s Associate Professor Charles Livingstone says</a>. This type of gambling is where things can easily turn sinister. To help keep things in check, limit your gambling to special occasions or events. That might be a flutter on the Melbourne Cup, a game of two-up on ANZAC Day, or a Lotto ticket as a birthday treat. It will mean more if it is tied to something special and an experience you can share with loved ones. Which leads into our next point: Avoid gambling alone Gambling by yourself can be a recipe for disaster. You don’t have a second pair of eyes over what you are doing or that trusted person to step in and say, ‘that’s enough’. In fact, I recommend couples always take a joint approach to their finances, regardless of whether gambling is involved. Leaving all the “money stuff” up to one of you means less accountability and opens the door for shared money and assets to be used improperly. Ask for help If you recognise things are getting out of hand, don’t suffer in silence. Talk things through with your partner, adult children or a trusted friend. Alternatively, contact <a href="https://www.gamblinghelponline.org.au/">Gambling Help Online</a> (1800 858 858) for free support 24/7 right across Australia.

How much do you need to retire? It’s probably a lot less than you think

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/brendan-coates-154644">Brendan Coates</a>, <a href="https://theconversation.com/institutions/grattan-institute-1168">Grattan Institute</a> and <a href="https://theconversation.com/profiles/joey-moloney-1334959">Joey Moloney</a>, <a href="https://theconversation.com/institutions/grattan-institute-1168">Grattan Institute</a> How much do you need to save for a comfortable retirement?

But for most Australians, it’s a lot less than you might think. <h2>You spend less in retirement</h2> Australians tend to overestimate how much they need in retirement. Retirees don’t have work-related expenses and have more time to do things for themselves. And retirees, especially pensioners, benefit from discounts on council rates, electricity, medicines, and other benefits worth thousands of dollars a year. While housing <a href="https://grattan.edu.au/news/the-great-australian-nightmare/">is becoming less affordable</a>, most retirees own their own home and have paid it off by the time they retire. Australians who own their home spend an average of 20–25% of their income on housing while working, largely to pay the mortgage. But that falls to just 5% among retiree homeowners, because they are just left with smaller things such as rates and insurance. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/631962/original/file-20241114-15-9h1dzt.png?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/631962/original/file-20241114-15-9h1dzt.png?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/631962/original/file-20241114-15-9h1dzt.png?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=337&fit=crop&dpr=1 600w, https://images.theconversation.com/files/631962/original/file-20241114-15-9h1dzt.png?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=337&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/631962/original/file-20241114-15-9h1dzt.png?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=337&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/631962/original/file-20241114-15-9h1dzt.png?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=424&fit=crop&dpr=1 754w, https://images.theconversation.com/files/631962/original/file-20241114-15-9h1dzt.png?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=424&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/631962/original/file-20241114-15-9h1dzt.png?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=424&fit=crop&dpr=3 2262w" alt="Notes: Housing costs include mortgage interest and principal repayments and general rates for homeowners, and rental payments for renters.

Super Consumers Australia (2023) Retirement Savings Targets</figcaption></figure> Crucially, these estimates account for the significant role of the <a href="https://www.servicesaustralia.gov.au/how-much-age-pension-you-can-get?context=22526">Age Pension</a> in the retirement income of many Australians. The <a href="https://www.servicesaustralia.gov.au/how-much-age-pension-you-can-get?context=22526">maximum Age Pension</a> is now A$30,000 a year for singles, and $45,000 a year for couples. To meet Super Consumers Australia’s “medium” retirement standard, a single homeowner needs to have saved only $279,000 in super by age 65 to be able to spend $41,000 a year. A couple needs only $371,000 in super between them to spend $60,000 a year. To meet their “low” standard – which still enables you to spend more than 30% of retirees – single Australians need $76,000 in super at retirement, and couples $95,000 (while also qualifying for a full Age Pension of $30,000 a year). That’s provided that you own your own home (more on that later). <h2>Ignore the super lobby’s estimates</h2> Australians should ignore <a href="https://www.superannuation.asn.au/resources/retirement-standard/">the retirement standards</a> produced by super lobby group the Association of Superannuation Funds of Australia. Their “<a href="https://www.superannuation.asn.au/resources/retirement-standard/">comfortable</a>” standard assumes retirees need an annual income of $52,085 as a single, and $73,337 as a couple. This would require a super balance of $595,000 for a single person, and $690,000 for a couple. But this is a standard of living most Australians don’t have before retirement. It is higher than what 80% of single working Australians, and 70% of couples, <a href="https://insidestory.org.au/the-reassuring-truth-about-retirement-incomes/">spend today</a>. For most Australians, saving enough to meet the super lobby’s “comfortable” standard in retirement can only come by being uncomfortable during their working life. <h2>Most Australians are on track for a comfortable retirement</h2> The good news is most Australians are on track. The federal government’s <a href="https://treasury.gov.au/sites/default/files/2021-02/p2020-100554-udcomplete-report.pdf">2020 Retirement Income Review</a> concludes most future Australian retirees can expect an adequate retirement, replacing a more-than-reasonable share of their pre-retirement earnings – more than the 65–75% benchmark nominated by the review. Even most Australians who work part-time or have broken work histories will hit this benchmark. Most retirees today feel more comfortable financially than younger Australians. And typically, they have enough money to sustain the same, or a higher, living standard in retirement than they had when working. <h2>Rising mortgage debt doesn’t change this story</h2> More Australians are retiring with mortgage debt – about 13% of over-65s had a mortgage in 2019–20, <a href="https://www.ahuri.edu.au/sites/default/files/migration/documents/AHURI_RAP_Issue_176_Housing-equity-withdrawal-in-Australia.pdf">up from 4% in 2002–03</a>. But the government’s <a href="https://treasury.gov.au/sites/default/files/2021-02/p2020-100554-udcomplete-report.pdf">retirement income review</a> found most retirees who used $100,000 of their super to pay off the mortgage when they retire would still have an adequate retirement income. This is, in part, because many would qualify for more Age Pension after using a big chunk of super to pay off the mortgage. And retirees can get a loan via the government’s <a href="https://www.servicesaustralia.gov.au/home-equity-access-scheme">Home Equity Access Scheme</a> to draw equity out of their home up to a maximum value of 150% of the Age Pension, or $45,000 a year, irrespective of how much Age Pension you are eligible for. The outstanding debt accrues with interest, which the government recovers when the property is sold, or from the borrower’s estate when they die, reducing the size of the inheritance that goes to the kids. <h2>But what about renters?</h2> One group of Australians is not on track for a comfortable retirement: those who don’t own a home and must keep paying rent in retirement. Nearly half of retired renters <a href="https://grattan.edu.au/news/repairing-australias-retirement-income-system/">live in poverty today</a>. Most Australians approaching retirement own their own homes today, but fewer will do so in future. Among the poorest 40% of 45–54-year-olds, just 53% own their home today, <a href="https://grattan.edu.au/news/the-great-australian-nightmare/">down from 71% four decades ago</a>. But a single retiree renting a unit for $330 a week – cheaper than 80% of the one-bedroom units across all capital cities – would need an extra $200,000 in super, in addition to Commonwealth Rent Assistance (according to the government’s <a href="https://moneysmart.gov.au/retirement-income/retirement-planner">Money Smart Retirement Planner</a>). This is why raising Commonwealth Rent Assistance to help renting retirees keep a roof over their heads should be an urgent priority for the federal government. Australians have been told for decades that they’re not saving enough for retirement. But the vast majority of retirees today and in future are likely to be financially comfortable.<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/243596/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/brendan-coates-154644">Brendan Coates</a>, Program Director, Economic Policy, <a href="https://theconversation.com/institutions/grattan-institute-1168">Grattan Institute</a> and <a href="https://theconversation.com/profiles/joey-moloney-1334959">Joey Moloney</a>, Deputy Program Director, Housing and Economic Security, <a href="https://theconversation.com/institutions/grattan-institute-1168">Grattan Institute</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

How to make gravy (using chemistry)

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/nathan-kilah-599082">Nathan Kilah</a>, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a> “Gravy Day” is a relatively new date in the Australian calendar. Paul Kelly’s song <a href="https://theconversation.com/humbug-tinsel-and-gravy-in-search-of-the-perfect-christmas-pop-song-88924">How to Make Gravy</a> tells the story of a prisoner (Joe) writing to his brother on December 21. Joe laments missing the family Christmas celebrations and asks who will make gravy for the roast lunch in his absence. While a roast may not be everyone’s idea of the perfect <a href="https://theconversation.com/a-festive-feast-of-fish-and-fruit-the-creation-of-the-australian-christmas-dinner-151201">Christmas feast</a>, “Gravy Day” does give the opportunity to discuss the chemistry involved in making gravy – a thickened sauce made from drippings collected from roasted meats. <h2>Give my love to Angus (beef?)</h2> Roasting meat sets off a cascade of chemical reactions, producing myriad new flavour chemicals. More than <a href="https://link.springer.com/chapter/10.1007/978-1-4615-2143-3_10#:%7E:text=This%20has%20resulted%20in%20the,and%20lean%20components%20of%20meat.">1,000</a> flavour compounds have been identified in roasted meats. Each chemical gives its unique characteristics to the taste and smell of the finished roast. The chemical <a href="https://www.sciencedirect.com/science/article/pii/S0308814698000764">12-methyltridecanal</a> helps give roast beef its “beefy” flavour, while the sulfur-containing compound <a href="https://www.sciencedirect.com/science/article/pii/S0963996922004422">2-methyl-3-furanthiol</a> is more often found in roast chicken. There are three main types of chemical reactions taking place when roasting meats that produce flavour chemicals. The <a href="https://theconversation.com/kitchen-science-from-sizzling-brisket-to-fresh-baked-bread-the-chemical-reaction-that-makes-our-favourite-foods-taste-so-good-58577">Maillard reaction</a> is responsible for both colour and flavour. This broad reaction type takes place between amino acids from the protein and sugars and simple carbohydrates found in the meat. The Maillard reaction is also the chemistry responsible for many favourite flavours, including roasted coffee, chocolate, steak, toast and more. <h2>A hundred degrees, even more maybe</h2> The other main type of reaction occurring in a hot oven is the breakdown of fats by “<a href="https://doi.org/10.1016/j.foodres.2022.111385">lipid degradation</a>”. This can form hundreds of different chemical compounds. Many of these chemicals are described as “fatty”, “tallowy”, or smell like fried foods. The unique fat profiles found in different animals translate to the profile of flavour chemicals that form from lipid degradation when roasted. Further flavour compounds can arise through the third type of reactions combining products of Maillard reactions and lipid degradation. One specific flavour compound identified as having a “gravy aroma” is known as <a href="https://pubs.acs.org/doi/10.1021/jf9023189">3-mercapto-2-methylpentan-1-ol</a>. This compound comes from roasted vegetables, so including some veggies in your roasting pan will give you more depth of gravy flavour. Also, “cutting onions” is a useful excuse if listening to How to Make Gravy gets you feeling emotional. <h2>The treasure and the trash</h2> Roasting meats causes the fats to “render” and separate from the meat as a liquid. The fat pools in the tray with flavour-rich meat juices. While the fat and the water both carry flavour compounds, too much fat can give the finished gravy an unpleasant mouth feel, or can separate into layers when served. It’s worth pouring off the pan juices into a jug to allow the fat to separate from the liquid so you can control how much fat you’re adding. Be sure to dispose of the excess fat responsibly – <a href="https://theconversation.com/why-shouldnt-i-pour-oil-or-paint-down-the-sink-and-what-should-i-do-instead-206604">don’t pour it down the drain</a>. <h2>Just add flour…</h2> Flour (or, more specifically, starch) is the secret ingredient of a good gravy. Starches are <a href="https://www.sciencedirect.com/science/article/pii/S0168945222000474">large complex chemicals</a> that are made up of lots of sugars joined together. Starch granules are tightly packed and swell greatly when they absorb water. The swollen starch molecules forms a gel-like network that traps water and oil to give a thickened gravy. Wheat flour is most often used as the starch source. Corn and arrowroot starch can also be used. They have a higher percentage of starch than flour and a more neutral flavour. Wheat starch typically requires a larger quantity to be added and longer cooking to form a paste. Whichever starch you use, don’t add it too quickly or without mixing as you’ll form lumps. <h2>…salt, red wine, and a dollop of tomato sauce</h2> Salt is a common ingredient when preparing roast meats, both on the surface of the meat to draw out moisture and as a flavouring agent. The pan juices are typically concentrated as part of the gravy making process. Make sure you taste the gravy before seasoning, as salt will be concentrated by heating. Additional flavour components can be introduced by adding red wine, sherry, stock, or tomato sauce. These ingredients will broaden the flavour profile through sweetness (sugar), acidity (vinegar, citric and malic acids), and umami in the case of tomato sauce (natural glutamates, such as those found in MSG). Some folk even add Vegemite to their gravy for an extra umami boost. <h2>I bet it will taste the same</h2> If you happen to have screwed up your gravy this time, or are after convenience, then you can turn to an instant gravy powder. The main ingredient is typically maltodextrin or another corn-derived (and possibly chemically modified) starch. Shelf-stable powdered fats, salt, colours, and a range of <a href="https://theconversation.com/busting-the-myth-that-all-food-additives-are-bad-a-quick-guide-for-label-readers-82883">flavour additives</a> will be present in varying amounts depending on the style and price point of the product. The advantages of the instant version are speed and uniformity due to the carefully controlled commercial production. So unlike Joe’s concerns for his family’s gravy, an instant gravy will be more likely to taste the same, regardless of who ends up making it.<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/219589/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/nathan-kilah-599082">Nathan Kilah</a>, Senior Lecturer in Chemistry, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Today Extra bids farewell to beloved reporter

Davina Smith has delivered all the latest breaking news to Today Extra viewers across the country for the last 10 years. In an emotional send off on Thursday, the beloved journalist became teary-eyed as she said her goodbyes on the show. "I'm just so thankful, it's the best job in the world, we have heartbreaking stories to tell, but the team behind the scenes are extraordinary," Davina said through tears. "We're so lucky to sit beside incredible people, but have people in our ears and in our hearts every day who are helping so much - thank you." Her colleague and dear friend David Campbell also had a special message for her. "I actually can't believe I'm doing this video," he began. "I just want to say that it's been a real honour to sit next to you, to work with you, I've learned so much over this period of time working with you. "I know we've had a lot of laughs, I know we've had a lot of banter, I know you've thrown a lot of pens at me, but I also wanted to tell you how much I actually respect you, not only as a journalist, but as a person, as a human and very much so as a parent. "You are going to be sorely missed, my friend, don't make me cry." Davina will continue to work for Nine, but is taking on a new role as a reporter for A Current Affair in Queensland. Her new role will give her more time to spend with her daughters, Hope and Rose and her husband mark. Images: Today
