How will Meta’s refusal to pay for news affect Australian journalism – and our democracy?

<a href="https://theconversation.com/profiles/peter-greste-616885">Peter Greste</a>, <a href="https://theconversation.com/institutions/macquarie-university-1174">Macquarie University</a> When we speak of media freedom, we generally mean it in terms of freedom from unnecessary legal restrictions, so journalists and their sources are not threatened with prosecution for exposing the misdeeds of governments. But the announcement by Meta (Facebook’s parent company) on March 1 that it will <a href="https://www.abc.net.au/news/2024-03-01/meta-won-t-renew-deal-with-australian-news-media/103533874">stop paying for Australian news content</a> poses a different kind of threat to media freedom. The most progressive <a href="https://theconversation.com/a-push-to-make-social-media-companies-liable-in-defamation-is-great-for-newspapers-and-lawyers-but-not-you-127513">media freedom laws</a> in the world are meaningless if news companies can’t afford to hire experienced journalists to run expensive investigations. It doesn’t matter how free the laws are if there are no journalists to do the reporting. A <a href="https://link.springer.com/chapter/10.1007/978-3-030-37265-1_4">key part of any successful democracy</a> is a free media, capable of interrogating the powerful and holding governments to account. Even in a world overflowing with digital content, we recognise the need for good journalism, produced to ethical and professional standards, to help inform public debate and good policy-making. <h2>It was always going to fall apart</h2> Three years ago, in 2021, under <a href="https://www.accc.gov.au/by-industry/digital-platforms-and-services/news-media-bargaining-code/news-media-bargaining-code">the News Media Bargaining Code</a>, the government forced Meta and Google to negotiate with news organisations and pay for the right to access and post their stories. The government introduced the code after <a href="https://www.aljazeera.com/economy/2024/3/1/facebook-owner-meta-to-end-deals-funding-news-in-australia-germany-france">Facebook and Google were accused of putting news content on their platforms</a>, while denying news organisations the advertising revenues that used to pay for journalism. Although we don’t know exactly who gets paid what, it is estimated that the two digital giants injected <a href="https://www.smh.com.au/politics/federal/1b-for-journalism-at-risk-in-new-warning-over-google-facebook-20240223-p5f78j.html">about $250 million a year</a> into Australian journalism. It wasn’t enough to end the crisis in news caused by the collapse of the old business models, but it <a href="https://www.aph.gov.au/Parliamentary_Business/Committees/House/Communications/Regionalnewspapers/Report/Section?id=committees%2Freportrep%2F024888%2F79305">helped prop up</a> a lot of struggling companies. In some cases, it helped pay for otherwise unprofitable forms of journalism. One of the big problems with the code was that it pushed media companies into inherently unstable and unpredictable deals with commercial behemoths, whose only interest in news was as a commodity to help drive profits. It was always going to fall apart, if and when news became too expensive and Facebook users became disinterested. It is hard to criticise Meta for deciding the deals weren’t worth it. The company is doing what it is supposed to, making hardheaded commercial decisions and maximising shareholder returns. But Meta’s interests are not the same as the Australian public’s. Or more accurately, Meta’s interests are not the same as our democracy’s. Meta doesn’t need high-quality news, particularly if its users are more interested in sharing family photos than sober reporting on inflation rates. But collectively, our society does need it. High-quality news is expensive. It doesn’t cost much to send someone to report on <a href="https://theconversation.com/why-are-taylor-swift-tickets-so-hard-to-get-the-economics-are-complicated-208567">Taylor Swift’s</a> Melbourne concert, but it is hugely expensive to cover <a href="https://theconversation.com/other-nations-are-applying-sanctions-and-going-to-court-over-gaza-should-nz-join-them-224132">the war in Gaza</a> or investigate allegations of government corruption. I suspect not that many Australians have read Adele Ferguson’s reporting about the <a href="https://www.smh.com.au/business/workplace/adele-ferguson-on-the-cost-of-whistleblowing-and-need-for-a-bank-royal-commission-20160505-gomxc4.html">corrupt practices of our biggest banks</a>. Her investigations took years of work, and cost far more than the Sydney Morning Herald would have recovered in subscriptions and advertising revenue for her stories. But her reporting triggered the <a href="https://www.royalcommission.gov.au/banking">Banking Royal Commission</a> and a suite of reforms that benefit everyone with a bank account. <h2>A news levy?</h2> If we accept that news is a public good, not something we can treat as a product to be traded like soap, then we have to develop economic models that somehow get the public to pay for it. It could be something like a levy – similar to Medicare’s – that recognises even if we don’t all consume news equally, we are collectively better off by having good journalism that’s free from commercial or political pressure. It is a difficult conversation to have, particularly when most Australians say <a href="https://www.edelman.com.au/trust/2023/trust-barometer">they don’t trust the media</a>, and more and more of us are <a href="https://www.canberra.edu.au/uc-alumni-canvas/canvas-articles/posts/news-blues-over-half-of-australians-avoid-the-news">giving up on news altogether</a>. And that brings us to the other truth this crisis has exposed: our consumption of media <a href="https://www.canberra.edu.au/about-uc/media/newsroom/2023/june/digital-news-report-australia-2023-tiktok-and-instagram-increase-in-popularity-for-news-consumption,-but-australians-dont-trust-algorithms">has changed irreversibly</a>. Fewer and fewer people are reading long news stories or wading through heavy TV bulletins. Now, short-form videos on TikTok, YouTube and Facebook are dominant. The news industry needs to meet audiences where they are, and accept that the ways of presenting news must also radically change. <figure><iframe src="https://www.youtube.com/embed/3RW1U9Q-lzw?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption>Our ways of consuming the news have changed, with short-form videos now dominant.</figcaption></figure> This is not to suggest all journalism should henceforth be presented as TikTok videos. But forcing digital giants to prop up analogue-era news companies cements a system that is no longer fit for purpose. By trying to make the big digital giants pay for content they ultimately profit from, the News Media Bargaining Code started with the right intention. But now that Meta has decided it is no longer worth it, we have a chance to radically rethink and redesign how we finance and deliver news – in a way that works for us all. Our democracy depends on 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/224872/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/peter-greste-616885">Peter Greste</a>, Professor of Journalism and Communications, <a href="https://theconversation.com/institutions/macquarie-university-1174">Macquarie University</a> This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

War in Ukraine affected wellbeing worldwide, but people’s speed of recovery depended on their personality

<a href="https://theconversation.com/profiles/luke-smillie-7502">Luke Smillie</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> The war in Ukraine has had impacts around the world. <a href="https://mitsloan.mit.edu/ideas-made-to-matter/ripple-effects-russia-ukraine-war-test-global-economies">Supply chains</a> have been disrupted, the <a href="https://news.un.org/pages/wp-content/uploads/2022/06/GCRG_2nd-Brief_Jun8_2022_FINAL.pdf?utm_source=United+Nations&utm_medium=Brief&utm_campaign=Global+Crisis+Response">cost of living</a> has soared and we’ve seen the <a href="https://www.unhcr.org/hk/en/73141-ukraine-fastest-growing-refugee-crisis-in-europe-since-wwii.html">fastest-growing refugee crisis since World War II</a>. All of these are in addition to the devastating humanitarian and economic impacts within Ukraine. Our international team was conducting a global study on wellbeing in the lead up to and after the Russian invasion. This provided a unique opportunity to examine the psychological impact of the outbreak of war. As we explain in a new study published in <a href="https://www.nature.com/articles/s41467-024-44693-6">Nature Communications</a>, we learned the toll on people’s wellbeing was evident across nations, not just <a href="https://ijmhs.biomedcentral.com/articles/10.1186/s13033-023-00598-3">in Ukraine</a>. These effects appear to have been temporary – at least for the average person. But people with certain psychological vulnerabilities struggled to recover from the shock of the war. <h2>Tracking wellbeing during the outbreak of war</h2> People who took part in our study completed a rigorous “<a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2773515/">experience-sampling</a>” protocol. Specifically, we asked them to report their momentary wellbeing four times per day for a whole month. Data collection began in October 2021 and continued throughout 2022. So we had been tracking wellbeing around the world during the weeks surrounding the outbreak of war in February 2022. We also collected measures of personality, along with various sociodemographic variables (including age, gender, political views). This enabled us to assess whether different people responded differently to the crisis. We could also compare these effects across countries. Our analyses focused primarily on 1,341 participants living in 17 European countries, excluding Ukraine itself (44,894 experience-sampling reports in total). We also expanded these analyses to capture the experiences of 1,735 people living in 43 countries around the world (54,851 experience-sampling reports) – including in Australia. <h2>A global dip in wellbeing</h2> On February 24 2022, the day Russia invaded Ukraine, there was a sharp decline in wellbeing around the world. There was no decline in the month leading up to the outbreak of war, suggesting the change in wellbeing was not already occurring for some other reason. However, there was a gradual increase in wellbeing during the month after the Russian invasion, suggestive of a “return to baseline” effect. Such effects are commonly reported in psychological research: situations and events that impact our wellbeing often (<a href="https://www.researchgate.net/publication/237535630_Adaptation_and_the_Set-Point_Model_of_Subjective_Well-BeingDoes_Happiness_Change_After_Major_Life_Events">though not always</a>) do so <a href="https://www.researchgate.net/publication/7062343_Beyond_the_Hedonic_Treadmill_Revising_the_Adaptation_Theory_of_Well-Being">temporarily</a>. Unsurprisingly, people in Europe experienced a sharper dip in wellbeing compared to people living elsewhere around the world. Presumably the war was much more salient for those closest to the conflict, compared to those living on an entirely different continent. Interestingly, day-to-day fluctuations in wellbeing mirrored the salience of the war on social media as events unfolded. Specifically, wellbeing was lower on days when there were more tweets mentioning Ukraine on Twitter/X. Our results indicate that, on average, it took around two months for people to return to their baseline levels of wellbeing after the invasion. <h2>Different people, different recoveries</h2> There are <a href="https://pubmed.ncbi.nlm.nih.gov/31944795/">strong links</a> between our wellbeing and our individual personalities. However, the dip in wellbeing following the Russian invasion was fairly uniform across individuals. None of the individual factors assessed in our study, including personality and sociodemographic factors, predicted people’s response to the outbreak of war. On the other hand, personality did play a role in how quickly people recovered. Individual differences in people’s recovery were linked to a personality trait called “stability”. Stability is a broad dimension of personality that combines low neuroticism with high agreeableness and conscientiousness (three traits from the <a href="https://www.sciencedirect.com/topics/social-sciences/big-five">Big Five</a> personality framework). Stability is so named because it reflects the stability of one’s overall psychological functioning. This can be illustrated by breaking stability down into its three components: <ol> <li> low neuroticism describes <a href="https://www.pnas.org/doi/full/10.1073/pnas.2212154120">emotional stability</a>. People low in this trait experience less intense negative emotions such as anxiety, fear or anger, in response to negative events </li> <li> high agreeableness describes <a href="https://psycnet.apa.org/record/2018-63285-010">social stability</a>. People high in this trait are generally more cooperative, kind, and motivated to maintain social harmony </li> <li> high conscientiousness describes <a href="https://doi.org/10.1016/j.paid.2023.112331">motivational stability</a>. People high in this trait show more effective patterns of goal-directed self-regulation. </li> </ol> So, our data show that people with less stable personalities fared worse in terms of recovering from the impact the war in Ukraine had on wellbeing. In a supplementary analysis, we found the effect of stability was driven specifically by neuroticism and agreeableness. The fact that people higher in neuroticism recovered more slowly accords with a wealth of research linking this trait with <a href="https://pubmed.ncbi.nlm.nih.gov/10573882/">coping difficulties</a> and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5428182/">poor mental health</a>. These effects of personality on recovery were stronger than those of sociodemographic factors, such as age, gender or political views, which were not statistically significant. Overall, our findings suggest that people with certain psychological vulnerabilities will often struggle to recover from the shock of global events such as the outbreak of war in Ukraine.<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/224147/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/luke-smillie-7502">Luke Smillie</a>, Professor in Personality Psychology, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Mind

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

<a href="https://theconversation.com/profiles/mia-cobb-15211">Mia Cobb</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> and <a href="https://theconversation.com/profiles/anne-quain-12802">Anne Quain</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> Cats kept indoors can <a href="https://safeandhappycats.com.au/">live a good life</a> when they get access to a variety of positive experiences. Examples include performing natural behaviours, feeling safe at home and using their full sensory capabilities, including their sense of smell. Plants such as catnip, cat thyme and silver vine are potent smelly stimulants that can affect cat minds and moods. Ever wondered if these mind-altering substances are safe gifts for our feline friends? And importantly, is it OK to provide these, or is offering catnip to a cat like offering alcohol to a child? <h2>Catnip, cat thyme and silver vine, oh my!</h2> Owners who are concerned about their cats feeling bored and frustrated might offer them fresh or dried catnip (Nepeta cataria), silver vine (Actinidia polygama), cat thyme (Teucrium marum) or other plant materials such as valerian (Valeriana officinalis) and Tatarian honeysuckle (Lonicera tatarica). These last couple <a href="https://bmcvetres.biomedcentral.com/articles/10.1186/s12917-017-0987-6">could offer an alternative</a> if your cat doesn’t respond to catnip. Toys filled with the leaves or extracts of these plants can cause apparently euphoric behaviour in domestic cats (as well as big cats like leopards and jaguars). Not all cats respond this way to these smells, which is <a href="https://bmcbiol.biomedcentral.com/articles/10.1186/s12915-022-01369-1">believed to have a genetic basis</a>. <h2>Are these treats safe for cats?</h2> Cats have a highly developed sense of smell. Some plants release chemical compounds to deter insects or to attract predators of insects that might otherwise destroy them. This includes <a href="https://www.science.org/doi/10.1126/sciadv.aba0721">nepetalactone</a>, an ingredient isolated from catnip and silver vine. Indeed, <a href="https://www.science.org/content/article/why-cats-are-crazy-catnip">it has been argued </a> that exposure to nepetalactone leads to an increase in feel-good hormones in cats. It may also act as a <a href="https://www.science.org/doi/10.1126/sciadv.abd9135">natural mosquito repellent</a> (note that it does not repel all mosquitoes and is not effective for flea or tick control). This may be why sniffing catnip, silver vine and some other plants causes cats to roll on their backs and rub their chins, cheeks and bodies on the plants. Other <a href="https://bmcvetres.biomedcentral.com/articles/10.1186/s12917-017-0987-6">observed behaviours</a> include: licking, shaking their head while carrying plant material in their mouth, drooling, kicking the plant material with their hind feet, and a “wavelike” motion of the skin over their backs as muscles contract and relax. These responses <a href="https://bmcvetres.biomedcentral.com/articles/10.1186/s12917-017-0987-6">generally don’t last long</a>, usually seconds to minutes, before cats relax or resume their normal behaviour. Rather than becoming addicted to these substances, cats are more likely to become habituated and desensitised, with the plants having less effect over time. When sniffed, these plants <a href="https://www.cell.com/iscience/fulltext/S2589-0042(23)01925-9">appear</a> to have <a href="https://bmcbiol.biomedcentral.com/articles/10.1186/s12915-022-01369-1">no adverse effects</a> on cats. <figure><iframe src="https://www.youtube.com/embed/yNUz4zQTA1E?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption>Cats (and a dog!) react to the active compound in catnip and silver vine, nepetalactone.</figcaption></figure> <h2>Is it ethical to alter the minds of our cats?</h2> When considering how to improve the lives of animals we care for, we tend to focus on whether the benefits outweigh the potential harms. Despite some marketing claims that these plants activates the brain’s opioid system, delivering a “natural high” for cats, there is no evidence these substances actually alter the minds of cats in the same way as alcohol or other drugs alter the minds of humans. The marketing of these cat treats as “kitty crack” or “<a href="https://www.meowijuana.com/">meowijuana</a>” and silver vine sticks as “<a href="https://www.nekopiapets.com.au/product-page/joycat-cat-cigarettes-silvervine-stick">kitty cigarettes</a>” is likely to deter some people from offering their cats <a href="https://bmcbiol.biomedcentral.com/articles/10.1186/s12915-022-01369-1">this kind of olfactory stimulation</a>. Unlike offering alcohol to a child, though, the evidence suggests our cats are OK when given access to these treats. These items won’t induce psychosis and won’t lead to addiction or withdrawal symptoms. And we don’t need to worry about our cats operating heavy machinery or making important decisions under the influence of mind-altering substances! Provided they can walk away at any time, it seems reasonable to let them opt in to a fun time. In fact, we harness the power of cats’ sense of smell in other ways by using <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6435919/">synthetic feline facial pheromones</a>. This can help reduce fear, anxiety and distress in cats. These substances can come in useful in settings such as multi-cat households or when moving house. <h2>How to make sure your cat has the purr-fect time</h2> Offering a range of smells (olfactory stimulation) is just one way to ensure your cat has a varied and interesting life. Here are some tips: <ul> <li> offer cats choices to interact with treats and toys – don’t force them </li> <li> rotate the toys and experiences on offer, so every day offers something fresh </li> <li> offer items that cats can scratch – scratching posts and corrugated cardboard are popular items </li> <li> if you are concerned your cat has swallowed part of a toy or seems unwell, check in with your vet. </li> </ul> Given the short-lived effects of these plant-based olfactory stimulants on cats, it is important that we <a href="https://www.sciencedirect.com/science/article/abs/pii/S0168159119301054">optimise their environment, lifestyle and interactions</a> with humans to improve their welfare. We can’t just rely on catnip or silver vine to give our cats a good life indoors – it’s really up to us!<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/214947/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/mia-cobb-15211">Mia Cobb</a>, Research Fellow, Animal Welfare Science Centre, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> and <a href="https://theconversation.com/profiles/anne-quain-12802">Anne Quain</a>, Senior Lecturer, Sydney School of Veterinary Science, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

How household gas leaks affect your home in Adelaide

<span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">If you're an Adelaide local, you'll know the city is as notorious for its hot summers as it is for its icy winters. One common necessity across all seasons is the reliance on gas. Be it for the central heating in winter or that gas oven whipping up a delightful roast, we can't really do without it. However, any discussion about gas and electricity supply here would be incomplete without addressing household gas leaks in Adelaide. <span style="font-size: 17pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: bold; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">The Silent Stalker: Gas Leaks <span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Often undetected and woefully underestimated, gas leaks can become a real concern if not addressed promptly. The main culprit in residential settings usually boils down to faulty gas appliances. An incorrectly installed gas appliance or ageing unit can develop leaks over time, silently emitting gas into your living space. <span style="font-size: 17pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: bold; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Signs of a Gas Leak <span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">So, what are the <a style="text-decoration: none;" href="https://cyberairconditioning.com.au/blog/what-do-gas-leaks-smell-like/"><span style="font-size: 11pt; font-family: Arial,sans-serif; color: #1155cc; background-color: transparent; font-weight: bold; font-style: normal; font-variant: normal; text-decoration: underline; -webkit-text-decoration-skip: none; text-decoration-skip-ink: none; vertical-align: baseline; white-space: pre-wrap;">indicators of a gas leak</a><span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">? In the absence of an instinctive warning, we might unknowingly be dealing with a perilous scenario right at our fingertips. Luckily, nature offers us a clear heads-up: our sense of smell. Indeed, that rotten-egg-like aroma you sniff is likely due to the addition of a chemical called Mercaptan to your natural gas supply, which serves as a leak alert. Thus, if your nose detects something unpleasant in the air, it's a credible signal that a gas leak is present. <img src="https://oversixtydev.blob.core.windows.net/media/2023/12/GasLeaks02.jpg" alt="" width="1280" height="720" /> <span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Apart from the smell, other signs include a higher-than-usual gas bill, dead patches on your lawn, or the persistent sound of a hissing near gas lines. <span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">So what do you do if you suspect a gas leak? Well, common sense and caution are your top mates here. <span style="font-size: 17pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: bold; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">When a Gas Leak Occurs <span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Start by making sure you're not creating an ignition source. This means avoiding lighting matches or using a cigarette lighter inside your home. Similarly, don't operate electrical equipment close to the suspected leak area. <span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Ensuring good air circulation is paramount in such situations, so swing open your doors and windows to facilitate the diffusion of the gas. If the odour is overpowering, promptly guide your loved ones and pets to a secure location outdoors. <img src="https://oversixtydev.blob.core.windows.net/media/2023/12/GasLeaks03.jpg" alt="" width="1280" height="720" /> <span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Once you're in a safe position, immediately dial emergency services. And remember, attending to a gas leak isn't a task you just anyone can do. <span style="font-size: 17pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: bold; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">What Happens If a Gas Leak Goes Unnoticed <span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">A frequently unobserved gas leak can pose significant dangers in your home. While it's crucial to heed the signs, smell gas, and call in professional help, it's also vital to understand what can happen if a gas leak goes unnoticed. As Adelaide homeowners, it's our responsibility to remain well-informed on the consequences of an ignored gas leak and be prepared to take swift action. <span style="font-size: 13pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: bold; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Health Hazards <span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">The primary danger of an unnoticed gas leak is its potential health impacts. Being exposed to leaking gas—from devices like stoves, heaters, or your gas water heater—can induce an array of symptoms, including <a href="https://www.oversixty.com.au/health/body/6-ways-to-combat-headaches-without-painkillers" target="_blank" rel="noopener">headaches</a>, dizziness, nausea, and weariness. These minor symptoms could potentially worsen to more critical health conditions, such as breathing difficulties, memory impairment, and in severe situations, unconsciousness. <span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Furthermore, carbon monoxide, an invisible and odourless hazardous gas that occurs from malfunctioning gas or electrical appliances, can lead to carbon monoxide poisoning. This condition can display symptoms resembling flu but can escalate to chronic neurological impairment or even prove fatal in the long run. <span style="font-size: 13pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: bold; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Fire or Explosion Risk <span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">A more immediate danger of an unnoticed gas leak is the potential for a fire or explosion. When the concentration of leaked gas in the air reaches a threshold level, even the smallest spark or open flame can ignite it. This might result from someone lighting a match or a cigarette lighter or inadvertently switching on an electrical device near the gas leak source. <span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Consequently, the ignited gas can cause a destructive fire or explosion, leading to significant property damage, serious injuries, or fatalities. <span style="font-size: 13pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: bold; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Environmental Impact <span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Say, for example, your outdoor gas metre is damaged or the gas pipes buried in your garden develop leaks. The escaped gas can cause harm to your plants and lawn, creating dead patches of grass, discoloured vegetation, or stunted growth. Furthermore, prolonged leaking of natural gas can contribute to greenhouse gas emissions, aggravating the issues of air pollution and climate change. <span style="font-size: 17pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: bold; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Call in the Experts: Licensed Gas Fitter <span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">When it comes to gas leaks, it's critical not to mess with things you're not licensed to handle. In Adelaide, turn to a licensed gas fitter for gas leak repairs. Your gas fitter is trained in gas leak detection and repair gas leaks to ensure the safety of your home. <img src="https://oversixtydev.blob.core.windows.net/media/2023/12/GasLeaks04.jpg" alt="" width="1280" height="720" /> <span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Further, regular inspections and proper installation of gas appliances can prevent gas leaks in the first place. If you've been regularly revamping your home with advanced gas installations and didn't already know this, well, you've been living under a rock, mate. <span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Proactive steps in your gas supply system, like the installation of carbon monoxide detectors and reviewing your gas metre's location, can help identify potential leaks and prevent dangerous carbon monoxide poisoning, exhibiting your perfect gumption. <span style="font-size: 17pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: bold; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Wrapping Up <span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">As part of the Adelaide community, it's essential to be aware of the potential hazards that household gas leaks can introduce into our homes.

How biological differences between men and women alter immune responses – and affect women’s health

<a href="https://theconversation.com/profiles/helen-mcgettrick-1451122">Helen McGettrick</a>, <a href="https://theconversation.com/institutions/university-of-birmingham-1138">University of Birmingham</a> and <a href="https://theconversation.com/profiles/asif-iqbal-1451123">Asif Iqbal</a>, <a href="https://theconversation.com/institutions/university-of-birmingham-1138">University of Birmingham</a> Most people will have heard the term “man flu”, which refers to men’s perceived tendency to exaggerate the severity of a cold or a similar minor ailment. What most people may not know is that, generally speaking, women mount stronger <a href="https://pubmed.ncbi.nlm.nih.gov/36121220/">immune responses</a> to infections than men. Men are <a href="https://journals.plos.org/plospathogens/article?id=10.1371/journal.ppat.1005374">more susceptible</a> to infections from, for example, HIV, hepatitis B, and Plasmodium falciparum (the parasite responsible for malaria). They can also have more severe symptoms, with evidence showing they’re more likely to be <a href="https://journals.plos.org/plospathogens/article?id=10.1371/journal.ppat.1005374">admitted to hospital</a> when infected with hepatitis B, tuberculosis, and Campylobacter jejuni (a bacteria that causes gastroenteritis), among others. While this may be positive for women in some respects, it also means women are at <a href="https://www.nature.com/articles/nri2815">greater risk</a> of developing chronic diseases driven by the immune system, known as immune-mediated inflammatory diseases. Here we will explore how biological factors influence immune differences between the sexes and how this affects women’s health. While we acknowledge that both sex and gender may affect immune responses, this article will focus on biological sex rather than gender. <h2>Battle of the sexes</h2> There are differences <a href="https://www.nature.com/articles/nri.2016.90">between the sexes</a> at every stage of the immune response, from the number of immune cells, to their degree of activation (how ready they are to respond to a challenge), and beyond. However, the story is more complicated than that. Our immune system evolves throughout our lives, learning from past experiences, but also responding to the physiological challenges of getting older. As a result, <a href="https://www.nature.com/articles/nri.2016.90">sex differences</a> in the immune system can be seen from birth through puberty into adulthood and <a href="https://academic.oup.com/jleukbio/advance-article/doi/10.1093/jleuko/qiad053/7190870">old age</a>. Why do these differences occur? The first part of answering this question involves the X chromosome. Females have two X chromosomes, while males have one X and one Y chromosome. The <a href="https://pubmed.ncbi.nlm.nih.gov/20651746/">X chromosome</a> contains the largest number of immune-related genes. The X chromosome also has <a href="https://link.springer.com/article/10.1007/s00018-020-03526-7">around 118 genes</a> from a gene family that are able to stop the expression of other genes, or change how proteins are made, including those required for immunity. These gene-protein regulators are known as microRNA, and there are only <a href="https://pubmed.ncbi.nlm.nih.gov/24808907/">two microRNA genes</a> on the Y chromosome. The X chromosome has <a href="https://www.genome.gov/about-genomics/fact-sheets/X-Chromosome-facts">more genes overall</a> (around 900) than the Y chromosome (around 55), so female cells have evolved to switch off one of their X chromosomes. This is not like turning off a light switch, but more like using a dimmer. Around <a href="https://bmcgenomics.biomedcentral.com/articles/10.1186/s12864-019-5507-6">15-25% of genes</a> on the silenced X chromosome are expressed at any given moment in any given cell. This means female cells can often express more immune-related genes and gene-protein regulators than males. This generally means a faster clearance of pathogens in females than males. Second, men and women have <a href="https://www.frontiersin.org/articles/10.3389/fimmu.2020.604000/full">varying levels</a> of different sex hormones. Progesterone and testosterone are broadly considered to limit immune responses. While both hormones are produced by males and females, progesterone is found at higher concentrations in non-menopausal women than men, and testosterone is much higher in men than women. The role of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6533072/">oestrogen</a>, one of the main female sex hormones, is more complicated. Although generally oestrogen <a href="https://www.sciencedirect.com/science/article/abs/pii/S000887491500026X?via%3Dihub">enhances immune responses</a>, its levels vary during the menstrual cycle, are high in pregnancy and low after menopause. Due in part to these genetic and hormonal factors, pregnancy and the years following are associated with heightened immune responses to external challenges such as infection. This has been regarded as an <a href="https://www.nature.com/articles/nri.2016.90">evolutionary feature</a>, protecting women and their unborn children during pregnancy and enhancing the mother’s survival throughout the child-rearing years, ultimately ensuring the survival of the population. We also see this pattern in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2628977/">other species</a> including insects, lizards, birds and mammals. <h2>What does this all mean?</h2> With women’s heightened immune responses to infections comes an increased risk of certain diseases and prolonged immune responses after infections. An <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3328995/">estimated 75-80%</a> of all immune-mediated inflammatory diseases <a href="https://pubmed.ncbi.nlm.nih.gov/32542149/">occur in females</a>. Diseases more common in women include multiple sclerosis, <a href="https://www.nature.com/articles/nri2815">rheumatoid arthritis</a>, lupus, Sjogren’s syndrome, and <a href="https://www.nature.com/articles/nri.2016.90">thyroid disorders</a> such as Graves disease. In these diseases, the immune system is continuously fighting against what it sees as a foreign agent. However, often this perceived threat is not a foreign agent, but cells or tissues from the host. This leads to tissue damage, pain and immobility. Women are also prone to chronic inflammation following infection. For example, after infections with <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5818468/">Epstein Barr virus</a> or <a href="https://www.liebertpub.com/doi/10.1089/jwh.2008.1193">Lyme disease</a>, they may go on to develop <a href="https://www.nhs.uk/conditions/chronic-fatigue-syndrome-cfs/">chronic fatigue syndrome</a>, another condition that affects more women than men. This is one possible explanation for the heightened risk among <a href="https://www.frontiersin.org/articles/10.3389/fresc.2023.1122673/full">pre-menopausal women</a> of developing long COVID following infection with SARS-CoV-2, the virus that causes COVID. Research has also revealed the presence of auto-antibodies (antibodies that attack the host) in patients with long COVID, suggesting it might be an <a href="https://www.sciencedirect.com/science/article/pii/S1568997221000550">autoimmune disease</a>. As women are more susceptible to autoimmune conditions, this could potentially explain the sex bias seen. However, the exact causes of long COVID, and the reason women may be at greater risk, are yet to be defined. This paints a bleak picture, but it’s not all bad news. Women typically mount <a href="https://pubmed.ncbi.nlm.nih.gov/24966191/">better vaccine responses</a> to several common infections (for example, influenza, measles, mumps, rubella, hepatitis A and B), producing higher antibody levels than men. One study showed that women vaccinated with half a dose of flu vaccine produced the same amount of antibodies compared to men vaccinated with <a href="https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/773453">a full dose</a>. However, these responses <a href="https://www.nature.com/articles/nri.2016.90">decline as women age</a>, and particularly <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3954964/">after menopause</a>. All of this shows it’s vital to consider sex when designing studies examining the immune system and treating patients with immune-related diseases.<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/208802/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/helen-mcgettrick-1451122">Helen McGettrick</a>, Reader in Inflammation and Vascular Biology, <a href="https://theconversation.com/institutions/university-of-birmingham-1138">University of Birmingham</a> and <a href="https://theconversation.com/profiles/asif-iqbal-1451123">Asif Iqbal</a>, Associate Professor in Inflammation Biology, <a href="https://theconversation.com/institutions/university-of-birmingham-1138">University of Birmingham</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Ballet flats are back. Here’s what the research says about how they affect your feet

<a href="https://theconversation.com/profiles/kristin-graham-1427672">Kristin Graham</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a>; <a href="https://theconversation.com/profiles/helen-banwell-305575">Helen Banwell</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a>, and <a href="https://theconversation.com/profiles/saravana-kumar-181105">Saravana Kumar</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> Ballet flat shoes – those thin-heeled lightweight slip-on shoes – are making a fashion <a href="https://www.vogue.com/slideshow/ballet-flats">comeback</a>. And it’s not hard to see why: they’re versatile, easy to wear, soft, flexible and often worn by celebrities. We have often been warned of the dangers of high-heeled shoes, so you might think ballet flats are problem-free. When you look at the research, however, a complicated picture emerges. There’s no definitive evidence to show ballet flats are generally harmful to foot health in the long-term. But ill-fitting ballet flats can be a problem. <h2>Make sure it fits, especially in the toe box</h2> An estimated <a href="https://pubmed.ncbi.nlm.nih.gov/30065787/">70%</a> of the population are wearing ill-fitting shoes. This mismatch between foot and shoe shape can increase foot pain, <a href="https://pubmed.ncbi.nlm.nih.gov/17507530/">reduce stability</a>, and can mean more blisters, corns and calluses. And habitual wearing of tight shoes has been <a href="https://www.sciencedirect.com/science/article/pii/S0958259207000533">associated</a> with bone changes in the toes and feet over time. Many flats feature a shallow and narrow toe box (the part of the shoe where the toes go). A too-small toe box often doesn’t align with the shape of a foot and ends up squishing the toes. It can also <a href="https://www.sciencedirect.com/science/article/pii/S0958259206000770">increase</a> pressure on top of and under the foot, and <a href="https://jfootankleres.biomedcentral.com/articles/10.1186/1757-1146-6-28">restrict</a> the movement of the forefoot during walking. But a too-big toe box is also a problem. Too much foot movement within the shoe can cause pressure and friction on the skin, which can also lead to calluses, corns, blisters, and wounds. A poorly fitting toe box can also cause micro trauma to toenails which, ultimately, can change <a href="https://www.researchgate.net/profile/Anuva-Bansal/publication/347522694_Traumatic_Nail_Disorders/links/60d6135592851ca94487df7e/Traumatic-Nail-Disorders.pdf">their look and thickness</a>. So if you’re wearing flats, make sure you choose a shoe with the right sized toe box. <h2>What about the heel?</h2> Health professionals often recommend a small heel over a completely flat shoe. Very flat shoes can <a href="https://pubmed.ncbi.nlm.nih.gov/27498844/">place</a> <a href="https://www.sciencedirect.com/science/article/pii/S0268003307002082">more</a> strain on the soft tissues that support the foot arch – specifically, the plantar fascia. <a href="https://pubmed.ncbi.nlm.nih.gov/27498844/">Research</a> has shown moving from a completely flat shoe to a small, raised heel reduces the tension force on the plantar fascia during standing activities. On the other hand, other <a href="https://journals.lww.com/jpojournal/Fulltext/2009/01000/Effects_of_Shoe_Heel_Height_on_the_Roll_Over.7.aspx#:%7E:text=The%20roll%2Dover%20shapes%20seem,without%20a%20change%20in%20alignment.&text=Photographs%20of%20the%20prosthetic%20feet,shapes%20of%20these%20feet%20superimposed">research</a> has shown most people will adapt their ankle and knee motion to accommodate shoes of different heel heights. <h2>What about support?</h2> Ballet flats tend to have very flexible, thin soles and heel counters (the part, coloured red in this picture, that hugs the heel and the back part of the foot). These thin and flexible structures mean flats are often accused of lacking support. But debate rages among foot and shoe experts about how important support is in the first place. <a href="https://pubmed.ncbi.nlm.nih.gov/27729290/">Research</a> on barefoot-style shoes has shown walking in these types of shoes significantly reduces some loads on the knee compared to more stable supportive shoes. Minimalist shoes have also been found to <a href="https://pubmed.ncbi.nlm.nih.gov/30102872/">increase strength</a> in certain foot muscles used when we push off during walking, running or jumping. However, other research found stable supportive shoes can <a href="https://pubmed.ncbi.nlm.nih.gov/33428439/">improve knee pain</a> when walking more than flat flexible shoes. The thin soles in flats mean there is little cushioning under the foot. While more cushioning can improve comfort, and reduce stress and strain on your foot sole <a href="https://www.sciencedirect.com/science/article/abs/pii/S0021929011001758?casa_token=gecXFCMi0LcAAAAA:TazyTd8TRaAl_bG0jprifYIUIlWRDwEH6bVeymBYTWups2iDGMuUjLs2gaNqsiNGHVJhHC3J9AdB">skin</a>, there is no evidence it reduces loads across the lower leg. In fact, walking in cushioned shoes has been shown to <a href="https://pubmed.ncbi.nlm.nih.gov/20191571/">increase</a> the load on the knee compared to flat, flexible shoes. <h2>So, what’s the verdict?</h2> The verdict is mixed. Yes, there’s evidence poorly fitting shoes and a flat heel can be detrimental, with consequences seen in the <a href="https://www.sciencedirect.com/science/article/pii/S0966636221000199">rearfoot</a> (around the ankle) and <a href="https://www.sciencedirect.com/science/article/pii/S0966636218300687">knee</a>. But there’s also no hard evidence ballet flats cause long-term foot health problems. What matters is choosing a well-fitted shoe to suit your foot shape and needs. If you’re shopping for ballet flats, try to: <ul> <li> choose a pair with a toe box that does not cramp your toes and has a sole at least as wide as your foot </li> <li> choose flats that offer at least some structure and support </li> <li> choose a pair with a small heel rather being than completely flat.<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/207806/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> </li> </ul> <a href="https://theconversation.com/profiles/kristin-graham-1427672">Kristin Graham</a>, Lecturer in Podiatry, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a>; <a href="https://theconversation.com/profiles/helen-banwell-305575">Helen Banwell</a>, Lecturer in Podiatry, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a>, and <a href="https://theconversation.com/profiles/saravana-kumar-181105">Saravana Kumar</a>, Professor in Allied Health and Health Services Research, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

How climate change will affect your pet – and how to help them cope

<a href="https://theconversation.com/profiles/edward-narayan-414899">Edward Narayan</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> Earth has just experienced its <a href="https://www.theguardian.com/science/2023/jul/27/scientists-july-world-hottest-month-record-climate-temperatures">hottest month</a> since records began and Australia is now gearing up for an El Niño-fuelled summer. Extreme heat isn’t just challenging for humans – it brings suffering to our beloved pets, too. <a href="https://www.cabidigitallibrary.org/doi/10.1079/cabireviews.2023.0020">Research</a> I was involved in examined how climate change affects the welfare of animals, including pets. My colleagues and I used a concept for assessing animal welfare known as the “<a href="https://kb.rspca.org.au/knowledge-base/what-are-the-five-domains-and-how-do-they-differ-from-the-five-freedoms/">five-domains model</a>”. It’s a science-based structure for examining an animal’s: <ul> <li>nutrition</li> <li>environment</li> <li>physical health</li> <li>behaviour</li> <li>mental state.</li> </ul> The model evaluates the complete physiological and behavioural responses of animals to environmental stressors. While the effects of climate change on animals have been studied before, ours is the first study to apply the model to animal welfare specifically. We examined the academic literature and found climate change will harm animals across all five welfare domains. This applies to both wild and domesticated animals, including pets. So let’s take a look at how various types of pets will fare in a warming world – and how we can help them. <h2>Fish</h2> Fish are “ectotherms” – that is, they use external sources of heat to regulate their body temperature. So pet fish are vulnerable to changes in the water temperature of your home aquarium, which may occur during a heatwave. Extreme water temperatures can cause physical harm to fish. For example, it can increase a fish’s metabolic rate – meaning it <a href="https://e360.yale.edu/features/feeling-the-heat-warming-oceans-drive-fish-into-cooler-waters">needs more oxygen</a> to breathe . It can also <a href="https://www.nepjol.info/index.php/ON/article/view/4331">cause changes</a> such as slowed growth and reduced feeding. According to <a href="https://agriculture.vic.gov.au/livestock-and-animals/animal-welfare-victoria/other-pets/caring-for-your-pet-fish">official advice</a>, water in an indoor aquarium should generally be kept at between 20℃ and 25℃ (unless you are keeping tropical fish). Depending on your budget and aquarium size, you could opt to use a device to control the water temperature. Either way, it’s important to monitor the water temperature regularly. Also make sure the aquarium isn’t located near a window where it’s exposed to direct sunlight. Leaving your aquarium unattended for days or weeks in summer can be dangerous, due to the risk of heatwaves. If you’re going on a summer holiday, consider organising a <a href="https://www.thesprucepets.com/holiday-and-vacation-fish-care-and-feeding-1378525#:%7E:text=If%20you%20are%20going%20on,aquarium%20and%20can%20prove%20lethal">fish sitter</a> to check on the animal regularly. <h2>Birds</h2> Heat stress can change the <a href="https://www.vetexotic.theclinics.com/article/S1094-9194(16)00003-7/fulltext">physiology</a> of birds. For example, research into a wild population of small Australian robins showed during a heatwave, the birds <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/jav.02355">lost body mass</a> and abandoned their nests, and some died. Heat stress can also cause <a href="https://www.tandfonline.com/doi/abs/10.1207/s15327604jaws0101_5">abnormal behaviour in pet birds</a> such as <a href="https://www.tandfonline.com/doi/full/10.1080/1828051X.2016.1195711?src=recsys">feather picking</a>, when one bird repeatedly pecks at the feathers of another. In hot weather, regularly check your bird’s cage to make sure it’s clean and stocked with food and water. If the bird is in an outdoor cage or aviary, ensure it is shaded. And a shallow bird bath will help your feathered friend cool off. <h2>Dogs</h2> Dogs and cats can suffer on hot days. That’s especially true if they are: <ul> <li><a href="https://www.ejmanager.com/mnstemps/100/100-1626960667.pdf?t=1657722662">older or overweight</a></li> <li>have thick coats</li> <li>have short snouts/flat faces (which restricts air flow and makes it harder for them to cool down).</li> </ul> Heat stress can cause <a href="https://www.frontiersin.org/articles/10.3389/fvets.2021.742926/full?&utm_source=Email_to_ae_&utm_medium=Email&utm_content=T1_11.5e2_editor&utm_campaign=Email_publication&journalName=Frontiers_in_Veterinary_Science&id=742926">canine hyperthermia</a>, which means the dog’s body temperature becomes dangerously hot. Watch for <a href="https://www.rvc.ac.uk/small-animal-vet/teaching-and-research/fact-files/heatstroke-in-dogs-and-cats#:%7E:text=Early%20signs%20of%20heatstroke%20in%20pet%20animals&text=Panting%2C%20this%20can%20progress%20to,Red%20gums%20or%20tongue">early warning signs</a> of heat stress such as excessive panting and erratic movements. These symptoms can quickly escalate, leading to heat stroke and possible death. <a href="https://pubmed.ncbi.nlm.nih.gov/34828033/">More than 80%</a> of dog owners report exercising their dogs less vigorously, or for shorter periods, during hot weather. That can help avoid heat-related illness. But don’t reduce your dog’s activity levels too much, as that may lead to other health problems. Just time the walks to avoid the heat of the day. Refrain from leaving dogs unattended in vehicles, because they can easily overheat. In fact, it’s better to leave your dog inside home on a hot day, as long as they have a cool place to rest and plenty of water – perhaps even with ice cubes in it. And dogs love to cool off in a kiddie pool or under a sprinkler. If you take your dog out on a hot day, <a href="https://agriculture.vic.gov.au/livestock-and-animals/animal-welfare-victoria/dogs/health/heat-and-pets#:%7E:text=Be%20aware%20of%20the%20signs,not%20icy%20water%20and%20fanned">carry</a> a container of fresh, cool water for them. And don’t forget to slip-slop-slap: apply a sparing amount of pet sunscreen to your dogs’ exposed pink skin such as ear tips and nose. <h2>Cats</h2> Like other animals, cats can overheat in hot weather. Symptoms include panting heavily, drooling and a rapid pulse. Like with other animals, if you suspect your cat is suffering from heatstroke, call a vet immediately. Climate change and associated heat and floods is likely to aid the spread of parasites and illness <a href="https://www.forbes.com/sites/jeffmcmahon/2022/12/31/guess-whos-loving-climate-change-mosquitos-and-the-pathogens-they-carry/?sh=50654683174a">including</a> tick-borne diseases, <a href="https://pubs.er.usgs.gov/publication/70213352">flea</a> infestations and <a href="https://pubmed.ncbi.nlm.nih.gov/32145530/">heartworm</a>. This puts both cats and dogs at risk. In hot weather, the advice for cat owners is similar to that of dog owners: ensure your cat has plenty of shade and water, and put pet sunscreen on their ear tips and noses, especially if the cat is white. If possible, keep the cat inside during the hottest part of the day. Ensure at least one room is cool and ventilated. And in a heatwave, play with your cat either in the early morning or evening, when the temperature has cooled. <h2>A helping human hand</h2> While humans have the capacity to understand and prepare for climate change, pets will need our help to cope. This includes not just the pets listed above, but others too, including reptiles, guinea pigs and rabbits. As heatwaves and other extreme weather events become more common, the onus is on us to keep our pets safe.<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/210724/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/edward-narayan-414899">Edward Narayan</a>, Senior Lecturer in Animal Science, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Does a woman’s menstrual cycle affect her athletic performance? Here’s what the science says

<a href="https://theconversation.com/profiles/sara-chica-latorre-1443479">Sara Chica-Latorre</a>, <a href="https://theconversation.com/institutions/university-of-canberra-865">University of Canberra</a> and <a href="https://theconversation.com/profiles/michael-pengelly-1443674">Michael Pengelly</a>, <a href="https://theconversation.com/institutions/university-of-canberra-865">University of Canberra</a> During the Women’s FIFA World Cup, it has been wonderful to see the spotlight turn to female athletes. There’s always been <a href="https://pubmed.ncbi.nlm.nih.gov/24766579/">more research on male athletes</a> compared to female athletes, but the gap is narrowing. One thing we still don’t know enough about is the effect of the menstrual cycle on athletic performance. <h2>What does the menstrual cycle do to a woman’s body?</h2> The menstrual cycle is a complex cascade of events typically lasting 28 days. The primary female sex hormones oestrogen and progesterone rise and fall as the body cycles through four phases, beginning at menstruation, maturation and releasing of an egg (ovulation), preparation for pregnancy, and restarting the cycle if the egg is not fertilised. Fluctuations in female sex hormones have been associated with changes in inflammation, metabolism, muscle activation and body composition, which <a href="https://pubmed.ncbi.nlm.nih.gov/33572406/">can influence athletic performance</a>. For instance, <a href="https://pubmed.ncbi.nlm.nih.gov/22306563/">inflammation decreases</a> when the body is preparing to ovulate, reaching its lowest point around ovulation. It then increases following ovulation and peaks during menstruation. This peak coincides with lower perceived performance among many female athletes. The menstrual cycle can also give rise to symptoms including pain, cramps, weakness, and poor sleep and focus, <a href="https://pubmed.ncbi.nlm.nih.gov/35911030/">challenging performance</a> during training and competition. For example, <a href="https://doi.org/10.1080/24733938.2021.2020330">research</a> conducted in elite female soccer players found over 87% of players perceived reduced power and increased fatigue during menstruation, while over 66% perceived their reaction time and recovery to be affected. Considering the approximate maximum career length of soccer players (21 years) and a woman’s fertile life, that adds up to about 250 times throughout a woman’s soccer career that performance may be compromised. Trends observed among female soccer players closely mirror the experiences of other female athletes, with over <a href="https://pubmed.ncbi.nlm.nih.gov/37389782/#:%7E:text=Results%3A%20Sixty%20studies%20involving%206380,the%20most%20prevalent%20MC%20disorder">74% reporting</a> negative effects mainly during the first days of menstruation. For some, this may lead to reduced training participation, potentially compromising skill development, fitness levels, and even their chances of being selected for competition. But the menstrual cycle is complex, and its effects can vary between athletes and sports. Consequently there is disagreement regarding whether the menstrual cycle universally affects athletic performance, with <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10076834/#:%7E:text=Findings%20suggest%20that%20strength%2Drelated,cause%20variations%20in%20strength%20performance">some research</a> <a href="https://pubmed.ncbi.nlm.nih.gov/32661839/">indicating</a> no influence of the menstrual cycle on certain performance measures. But these studies are few and had various logistical limitations, including a small number of participants. Also important to note is that most studies to-date have excluded women using hormonal contraceptives, which is about <a href="https://pubmed.ncbi.nlm.nih.gov/29283683/">50% of female athletes</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/35475746/#:%7E:text=Conclusion%3A%20Most%20WSL%20players%20do,minimise%20discomfort%20and%20maximise%20performance.">28% of female soccer players</a>. The use of hormonal contraceptives suppresses natural hormonal fluctuations and replaces them with external synthetic versions of female sex hormones, affecting the athlete differently. Clearly the extent and severity to which the menstrual cycle impacts athletic performance is highly variable and complex, with more research needed. So for now it’s sensible to consider the effects of the menstrual cycle on an individual basis. <h2>How to support athletic performance at all cycle stages</h2> It’s essential for players to familiarise themselves with their own cycles to understand how they’re affected throughout, as well as communicate any menstrual cycle-related issues to support staff (physicians and coaches). This awareness can guide adjustments in training and nutrition when required. For example, oestrogen has an important influence on iron levels in females, such as chronic oestrogen deficiency is <a href="https://pubmed.ncbi.nlm.nih.gov/23041085/">linked to iron deficiency</a>. Iron status can also be compromised by blood loss during menstruation, depending on the heaviness and duration of bleeding. Iron is essential for human function, facilitating energy production and the transportation of oxygen around the body. In soccer, about <a href="https://pubmed.ncbi.nlm.nih.gov/16521852/#:%7E:text=Of%20the%20investigated%20female%20soccer,at%20the%20top%20international%20level">60% of elite female players</a> present as iron deficient, compared to <a href="https://pubmed.ncbi.nlm.nih.gov/18384395/">less than 12% of their male counterparts</a>. For an iron deficient midfielder, this might translate into covering less distance at lower speeds. It’s therefore important female athletes have their iron levels regularly checked by qualified practitioners. Addressing deficiencies through diet, supplementation, or iron transfusions, will ensure athletic performance during training and competition is not compromised. Individual athletes’ training loads can also be strategically managed to accommodate severe menstrual symptoms. Football clubs around the world have been <a href="https://www.tandfonline.com/doi/full/10.1080/24733938.2020.1828615">experimenting with this strategy</a> since it gained popularity during the 2019 Women’s FIFA World Cup. But how does it look in practice? For team sport athletes, such as soccer players, this can be a demanding logistical task. It’s not easy to track the menstrual cycles of more than 25 players concurrently, and hold training sessions at convenient times for all of them. The complexities are heightened when training and game days cannot be avoided. But performance coaches must consider athletes’ needs and ensure they’re prepared for competition, while minimising the risk of injury and menstrual discomfort. Coaches should also ensure athletes maintain adequate nutrition for both competition and to support their menstrual cycle. For an athlete who reports severe menstrual symptoms during the first days of menstruation (such as increased pain and weakness), this might translate into reduced training intensity, additional recovery days, and an anti-inflammatory diet that also supports the restoration of iron levels (increased intake of nuts, seeds, berries, lean red meats, and fibre and Omega-3 rich foods). And it’s important to keep in mind some athletes might experience menstrual cycle issues in phases other than menstruation. So, training and nutrition should be flexible and individualised across the cycle. Using this approach, athletes can mitigate the influence of the menstrual cycle on their performance, giving them the best opportunity to achieve their athletic potential and success during competition.<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/206700/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/sara-chica-latorre-1443479">Sara Chica-Latorre</a>, Phd Candidate and Research Assistant, Research Institute for Sport and Exercise, <a href="https://theconversation.com/institutions/university-of-canberra-865">University of Canberra</a> and <a href="https://theconversation.com/profiles/michael-pengelly-1443674">Michael Pengelly</a>, PhD Candidate, Research Institute for Sport and Exercise, <a href="https://theconversation.com/institutions/university-of-canberra-865">University of Canberra</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

8 sneaky ways not getting enough sleep affects your looks

Your skin cells don't have time to repair themselves “The evening is a time of rest and repair, when the skin heals itself from daily damage,” says dermatologist Dr Joshua Zeichner. “If you are not sleeping, then your skin will not be able to heal itself and may increase your likelihood of premature ageing.” Breakouts can - and probably will - pop up Your levels of cortisol (the stress hormone) naturally drop at night. But when you stay up late and disrupt your sleep cycle, cortisol levels remain high. This means your oil glands are continually stimulated, which can make you more likely to get an acne breakout, explains Dr Zeichner. Your pores will look bigger Another side effect of increased oil production brought on by lack of sleep is clogged and dilated pores. Your risk of sun damage increases “Normal sleep is needed for production of your body’s natural antioxidant stores,” says Dr Zeichner. “It has been shown that sleep deprivation results in a decrease in antioxidant production, which interferes with your skin’s ability to protect itself from environmental stressors the next day, including UV light, pollution, and exposure to cigarette smoke.” Your risk of skin infection goes up “Sleep deprivation has been shown to affect your immune system, lowering your white blood cells,” Dr Zeichner says, “so a lack of sleep may increase your risk of skin infections.” A few of these infections can include the fungal variety (athlete’s foot and ring worm) as well as cellulitis and folliculitis (a big word for an ingrown hair). Your under-eye bags get deeper and darker Your lymph system is like your waste disposal system, helping to filter excess fluid and toxins and, according to Dr Zeichner, there is some data that suggests a lack of sleep does interfere with your lymphatic drainage. “If the fluid is not drained away, it may accumulate, leading to puffiness and increase your under-eye bags.” Also, keep your diet low in sodium, to prevent fluid accumulation. Sallow complexion much? “Lack of sleep interferes with the normal circadian patterns in your skin, including night time skin repair,” tells Zeichner. “This may interfere with normal skin cell turnover, leading to the accumulation of cells on the skin’s surface and a dull complexion.” That means your skin may look dull or grey. A good exfoliation treatment will help brighten your skin right up. Your psoriasis and eczema may flare up Stress is a common trigger for chronic skin conditions including psoriasis and eczema. When you don’t get enough sleep the chances are good that your stress levels will go up, along with your production of cortisol. An early study has shown a connection between sleep and psoriasis and other studies have shown that lack of sleep damages your skin barrier, making an eczema flare-up more likely.

How beauty filters like TikTok’s ‘bold glamour’ affect tweens using social media

<a href="https://www.cosmopolitan.com/entertainment/celebs/a43203022/tiktok-bold-glamour-filter/">TikTok’s new “bold glamour” filter</a> “enhances” physical features in a way that makes it difficult to distinguish whether someone is using a filter or not, despite its airbrushing qualities. Unlike its predecessors, this filter allows movement through an AI feature with the filter remaining fixed on when, for example, a hand crosses the face, with fewer glitches. Users could be left comparing their unfiltered appearance with their “perfect” filtered self. They may start to develop unrealistic goals of perceived physical perfection that affect their self esteem. Although the terms of service for most social media platforms require users to be at least 13, a significant number of “tweens” (children between the ages of nine and 12) <a href="https://www.ofcom.org.uk/research-and-data/media-literacy-research/childrens/children-and-parents-media-use-and-attitudes-report-2022">now have a social media profile</a>. Online safety lessons in schools <a href="https://www.childrenscommissioner.gov.uk/wp-content/uploads/2018/01/Childrens-Commissioner-for-England-Life-in-Likes-3.pdf">tend to concentrate</a> on physical risk and predatory behaviour rather than emotional risks that children may encounter, as these may not be as apparent or experienced by adults. <blockquote class="twitter-tweet"> I am old enough and tough enough that filters don’t have an impact on me. My face tells the story of my life and I know its value; I can (mostly) look at who I am with love and acceptance. But if I had had access to Tiktok’s Bold Glamour as a kid, I would have been destroyed. <a href="https://t.co/USjFcLJkoh">pic.twitter.com/USjFcLJkoh</a> — Rebecca Seal (@RebeccaSeal) <a href="https://twitter.com/RebeccaSeal/status/1640275766100279296?ref_src=twsrc%5Etfw">March 27, 2023</a></blockquote> The <a href="https://journals.sagepub.com/doi/abs/10.1177/1461444819873644">damaging effect of “filters”</a> (digital image effects that alter a person’s appearance) is less commonly taught. <a href="https://www.tandfonline.com/eprint/KXDECXZB3CVNZNDHNURF/full?target=10.1080/03004279.2022.2095416">In my research</a>, I presented eight focus groups with activities to generate discussions with children of 10 and 11 years of age who were in their final year of primary school. One of the activities was related to the use of filters. Participants were given a set of photographs of people using filters on the social media site Snapchat and were asked questions such as: “How are these different from how they look in real life?” and “why do people use these filters?” The results demonstrated a clear and distinct gender divide. The boys said they used filters for fun and entertainment, favouring dog ears and exaggerated tongues to “make people laugh”. The girls used filters to create an idealised image that conformed to beauty ideals and for validation in the form of likes and comments. One girl, Samantha, said: “[filters] make you look perfect and flawless”. Another explained: “I like putting filters on because it doesn’t show my birthmark at all. It takes the blemishes off my face”. Similarly, tween Mia explained: “when you put a filter on, it makes your skin tone better and it covers up any spots or like any bruises and stuff that you feel insecure about in yourself.” My findings suggest that girls are internalising and aspiring to the beauty ideals that they are consuming via social media. There is a pressure to adopt a polished, physical appearance through filters, which may have <a href="http://sro.sussex.ac.uk/id/eprint/82913/3/__smbhome.uscs.susx.ac.uk_dm50_Desktop_Jaynes%20V.pdf">emotional repercussions</a>. <h2>‘Beauty isn’t everything’</h2> I also used collaging as an activity for exploring individual experiences. One child, Sophie, chose to show a binary depiction of herself as two halves. On the social media side, she used lots of different animal prints in triangles to show that you can be lots of different things and there are lots of different parts of yourself. She explained that the patterns she had chosen looked unnatural, unlike the more realistic filters online. Because (like other females in the study) she felt that there is an expectation for girls to look a certain way, Sophie also wrote “no one is perfect” on her collage. For the girls in my research, there was a sense that self expression was strongly linked to appearance, with a <a href="https://pubmed.ncbi.nlm.nih.gov/26612721/">pressure to adhere</a> to certain perceived physical ideals. In her collage, Karen discussed at length how social media can be an augmented reality and can emphasise feelings of self consciousness linked to physical appearance. The characters drawn on her collage show a “real-life” self that had no filter, which “makes her sad” and a “filter self” which used make up and filters to enhance her appearance and made her happy. She also emphasised the feelings of negative self-esteem that viewing filtered images could have by saying, "People try and make themselves look beautiful and at the end it may really disappoint them." <a href="https://journals.sagepub.com/doi/abs/10.1177/1461444819871669?journalCode=nmsa">Similar research from 2020</a> also concluded that girls tend to replicate “female” cues popularised through social media patterns, such as exaggerated lips and flawless skin. Although my research specifically focused on Snapchat, other social media platforms such as TikTok and Instagram also encourage enhancing appearance through filters. Beauty filters reinforce the message that wearing makeup, looking a certain way and conforming to beauty ideals, is the desired physical state for women. Isabel had a strong message for girls in her collage: “be your own person and stop comparing yourself to others”. The widespread use of filters is certainly not facilitating this message and it is important that the emotional repercussions of using these appearance altering tools – as well as continually seeing them in social media feeds – is addressed. Open discussions could help educate girls to learn that these unattainable physical aspirations do not represent reality.

What are microaggressions? And how can they affect our health?

Microaggressions are seemingly innocuous verbal, behavioural or environmental slights against members of minority communities. The term microaggressions was coined by American psychiatrist Chester Pierce in his 1970 essay Offensive Mechanisms. He explained: <blockquote> Most offensive actions are not gross and crippling. They are subtle and stunning. The enormity of the complications they cause can be appreciated only when one considers that these subtle blows are delivered incessantly. Even though any single negotiation of offence can in justice be considered of itself to be relatively innocuous, the cumulative effect to the victim and to the victimiser is of an unimaginable magnitude. </blockquote> While originally conceived in the context of race relations, microaggressions may also relate to gender, sexual orientation, religion, disability status, weight, or a combination of these. <h2>What do microaggressions look like?</h2> Consider these situations. All are real-life stories from people of colour I know (used with their consent): <ul> <li> a woman walks into a hairdresser’s shop. The shop is empty and the hairdresser is cleaning hair from the floor. The woman asks if she could get a haircut – if not right now, perhaps another day. The hairdresser says she can’t help as she is not taking on any new customers. </li> <li> a man is waiting to pick up his partner in his car, parked on a side street near his partner’s apartment, which is located in a predominantly white suburb. He is minding his own business sitting in his own car. Each time a person walks by, they stare at the man, and keep staring as they walk past </li> <li>a couple is waiting to order coffee in a busy city cafe. The server is chatty with the white couple ahead of them. When they progress to the front of the line, the server is curt, avoids eye contact, and is eager to move on to the next customer. After placing their order, the couple stands where other patrons had previously waited for their orders. A staff member comes over and asks the couple to wait outside instead.</li> </ul> Examples of microaggressions towards other identity minorities may include moving away from a trans person on public transport, or not considering wheelchair accessibility needs when booking venues for meetings or events. Each of these incidents in isolation may not seem particularly harmful, and some may even chalk them up to coincidences or “reading too much into a situation”. However, when experienced repeatedly, daily, or even multiple times a day, they can harm people’s psychological and physical health. <h2>Microaggressions are subtle</h2> Microaggressions are often so subtle that even the victim may not realise that they have just experienced one until later – likely because microaggressions are often accompanied with dissociation (i.e. disconnection from thoughts, feelings or personal sense of identity). As psychologist Ron Taffel explains, dissociation is a “psychically handy” tool that helps ease the pain, <blockquote> making sure that the moment does not fully register or does its damage until a less vulnerable time later – perhaps during a quiet time alone… </blockquote> <h2>Microaggressions affect our physical and mental health</h2> Microaggressions can occur in all environments, from the workplace, to shops, medical clinics, schools, universities, even while walking or parked on the street. So victims often become increasingly self-conscious and hypervigilant. The impacts of microaggressions may extend beyond psychological burden and also impact the body’s physiological state. When humans perceive a sense of imminent danger, the body’s “fight, flight, freeze response” is activated. While this is a useful evolutionary mechanism to protect us from physical danger, when triggered frequently – as may be the case with microaggressions – it can take a toll on the body and contribute to issues such as high blood pressure, anxiety, depression and addiction. Racial microaggressions have also been associated with suicide risk. One study found experiencing race-related microaggressions leads to more symptoms of depression, which in turn increases thoughts of suicide. <h2>Microaggressions may deter people from seeking help</h2> Health issues among victims may be further compounded when microaggressions are experienced in the health-care sector. A study from 2011 found that sexual orientation-related microaggressions (for example, derogatory comments or assumptions about a person’s sexual orientation) reduced the likelihood of LGBTIQ+ people seeking psychotherapy and impacted their attitudes towards therapy and therapists. Research involving Indigenous people also suggests microaggressions impact help-seeking behaviours in this group (such as not scheduling or attending regular health-care appointments), which subsequently increases the risk of hospitalisation. <h2>Indirect effects of microaggressions</h2> Microaggressions may also impact people’s health status indirectly. Research suggests repeated microaggressions can cause marginalised groups to internalise feelings of inadequacy. Over time, this internalised oppression may impact their academic and professional success, and consequently socioeconomic status. <h2>Sceptics and victim-blaming</h2> Sceptics often attribute microaggressions to victims’ “negative emotionality” – a tendency to show negative affect and always feel like a victim. However, proponents argue that this is a form of victim-blaming that further compounds the harm caused by microaggressions. Clinical psychologist Monnica Williams suggests that the years of unchecked microaggressions themselves could be the very thing to cause negativity in marginalised people. <h2>Victims’ responses to microaggressors</h2> Victims’ responses to microaggressions can vary among people, and among events experienced by the same person. Victims have to regularly decide whether to let it slide or confront the aggressor. The discourse on microaggressions in social media seems to be on the rise. One study found that there was a drastic increase in the usage of the term “microaggression” on Twitter between 2010 and 2018. Social media discussions and other online spaces may help victims (particularly younger people) to respond more critically to microaggressors. Other technological innovations, such as the virtual reality-based intervention Equal Reality, are also helping people walk in another’s shoes, recognise unconscious bias, mitigate risk of microaggressions, and promote more inclusive workplaces.

Have you found ‘the one’? How mindsets about destiny affect our romantic relationships

If you listen to any number of love songs, dating “experts”, or plunge head first into a romance novel, you’re likely to think it’s in our destiny to find that special someone – your soul-mate. But how do you know if you’ve found “the one”? Will the birds sing? Will you see fireworks or a shooting star? And for those who are yet to find “the one”, should you keep searching, or is it a misguided quest? Research into the science of relationships spanning the last two decades shows maintaining a “<a href="https://journals.sagepub.com/doi/abs/10.1207/S15327957PSPR0701_3">destiny</a>” mindset – that we are all <a href="https://journals.sagepub.com/doi/abs/10.1207/S15327957PSPR0701_3">meant to find that ideal person</a> who completes us in every way – can be problematic for our love lives. Destiny mindsets affect how we <a href="https://psycnet.apa.org/record/1997-38975-006">evaluate romantic partners</a>, as well as how we maintain <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/1475-6811.09401">lasting relationships</a>. For some, this mindset can even include a mental picture as to what that person should look like. <h2>What are the costs of a mindset?</h2> A destiny mindset may make a person less open to developing a relationship with someone who possesses many excellent qualities, but does not match an individual’s mental picture of “the one”. A person who holds a destiny mindset may be more likely to focus on the potential faults or inadequacies of another, for example, rather than centre on their good qualities. On the other hand, a person may not pursue a potential love interest in the hope that something better comes along that matches their vision of destiny. By maintaining a destiny mindset, they may reject real <a href="https://scholarship.richmond.edu/honors-theses/487/">opportunities at finding love</a>. For those in an existing relationship, maintaining a destiny mindset can be associated with relationship satisfaction, if the current relationship closely (if not perfectly) matches one’s idea. But if the relationship is not in line with one’s vision of destiny, or if the relationship is evaluated as no longer matching one’s destiny, <a href="https://journals.sagepub.com/doi/abs/10.1177/0146167201277004">dissatisfaction can ensue</a>. Research suggests people who hold a destiny mindset don’t work as hard at their <a href="https://psycnet.apa.org/record/2012-32735-009">relationships</a> because they have a very fixed view of their partner and relationship. They tend to accept things the way they are – <a href="https://psycnet.apa.org/record/2006-04109-008">either a relationship is meant to be or it is not</a> – rather than putting in time and effort to make relationships things work and <a href="https://psycnet.apa.org/record/2012-32735-009">deal with relationship problems</a>. <h2>Is there a better alternative?</h2> In contrast to a destiny mindset, some people hold a “growth relationship” mindset. This includes beliefs and expectations that a partner and relationship has the capacity to develop and change over time, and that <a href="https://journals.sagepub.com/doi/abs/10.1207/S15327957PSPR0701_3">problems or challenges can be overcome</a>. Research to date suggests a growth mindset is associated with more effective ways of coping with relationship challenges and using more <a href="https://psycnet.apa.org/record/2012-32735-009">problem-solving to deal with relationship difficulties</a>. People with a growth mindset experience various positives such as greater <a href="https://psycnet.apa.org/record/1997-38975-006">relationship</a> and <a href="https://psycnet.apa.org/fulltext/2016-52940-001.html">sexual satisfaction</a> and have a better, more constructive way of handling <a href="https://psycnet.apa.org/record/2012-32735-009">conflict</a>. A growth mindset has also been found to reduce the risk of <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/1475-6811.09401">a relationship ending</a>. <h2>Can you have both?</h2> Some people recount meeting their partner and knowing they were “the one”. But when describing how their relationship has progressed over time, it’s clear they put time and effort into it and work on problems when they arise. These people may hold beliefs about destiny, but overall, hold more of a growth mindset about their relationship. These couples often acknowledge their partner and relationship has changed, for example, and often note that they’ve helped each other develop and grow over time. So if you work hard at your relationship, and you and your partner help one another develop and grow, you may get to know each other so well that you feel as if you share one soul. Maybe that’s what is meant by a true soul-mate.

Sleepless nights can affect your memory

One-third of a life span is a massive slice of time to spend with our eyes closed, but there's a very good reason humans need so much sleep. We just don't know what it is. What does sleep do to our brains? Like a sleep-deprived student trying to muddle through a morning exam, scientists trying to unravel this enduring mystery have been labouring in a heavy fog. But a new study could help answer this fundamental question, suggesting those hours of slumber allow the brain to rewire the crucial connections between the brain's neurons that clog up when we're awake. This nightly reset is vital for building and preserving memory, as well as our ability to learn new skills and engage with our waking realities, according to the German researchers. But just one sleepless night may be all it takes to stop the brain's ability to recalibrate its connections, overloading its synaptic activity and ultimately hampering its ability to form and retain new memories, according to the research paper published on Wednesday in <a href="http://nature.com/articles/doi:10.1038/ncomms12455" target="_blank" rel="noopener">Nature Communications</a>. The researchers set out to test the "synaptic homeostasis hypothesis" that a good night's sleep allows the brain's neuron signals to cut through the chaotic "noise" and improve its capacity to encode, or remember, new information. It is virtually impossible directly test this theory in humans. Using non-invasive transcranial magnetic stimulation (TMS), the research team was able to indirectly compare the synaptic activity in the brains of 20 individuals (aged between 19 and 25) after one night's sleep or after one night of sleep deprivation. The research team used small magnetic pulses to zap the motor cortex - the region responsible for movement - to trigger a muscle twitch in participant's left hands. After their sleepless night, participants needed a much lower pulse to activate the hand muscles compared their well-rested counterparts, suggesting their sleep-deprived brains were more excitable, said the researchers lead by psychiatrists Dr Christoph Nissen at Freiburg University, Germany. The researchers then used the magnetic pulses to imitate the brain activity used to encode new memories. The sleep-deprived participants showed a weaker synaptic response and performed worse in a word-pair memory exercise. Their blood samples also showed reduced BDNF, a molecule that regulates synaptic plasticity needed for memory and learning. "Our study provides the first evidence for sleep-wake-dependent dissociation of associative and homeostatic synaptic plasticity in humans," the researchers concluded. The results may pave the way for effective treatments for neuropsychiatric disorders. There is some evidence the experimental treatment - therapeutic sleep deprivation - can improve mood among people with major depression. The findings suggest the therapy shifts the brain of a depressed patient "into a more favourable window of associative plasticity", the authors suggested. Overall, "the findings were a significant step towards a better understanding of basic mechanisms for health performance and potential alterations in neuropsychiatric disorders," they concluded. What’s the minimum amount of sleep you can survive on before your cognitive performance is affected? Let us know in the comments below. Written by Kate Aubusson.

How financial stress can affect your mental health and 5 things that can help

Financial stress is affecting us in many different ways. Some people are struggling to pay bills, feed the family, or maintain a place to live. Others are meeting their basic needs but are dipping into their savings for extras. Financial stress <a href="https://www.anu.edu.au/news/all-news/australians-under-increasing-financial-stress">is increasing</a> and, understandably, is causing some distress. In recent months, Lifeline has seen a <a href="https://www.lifeline.org.au/media/qhmfdsit/lifeline-is-here-to-support-people-struggling-with-the-mental-wellbeing-effects-of-cost-of-living-pressures.pdf">rise</a> in the number of calls about financial difficulties. But understanding and finding ways to reduce our financial stress – and its emotional impact on us – can help make this challenging time a bit easier. <h2>What is financial stress?</h2> If you’re finding it difficult to meet your current expenses or are worried about your current or future finances, you’re under <a href="https://onlinelibrary.wiley.com/doi/10.1002/smi.2688">financial stress</a>. Like other types of stress, financial stress has two components: <ul> <li> objective financial difficulty, where you don’t have enough funds to cover necessary expenses or debts </li> <li> subjective perceptions about your current or future finances, leading to worry and distress. </li> </ul> These two are related. But someone can have trouble meeting their expenses, view this as acceptable, and not be overly worried. Alternatively, someone may be reasonably financially secure but still feel quite stressed about their finances. <h2>Why are we feeling it?</h2> There is a <a href="https://www.sciencedirect.com/science/article/abs/pii/S0148296317301005?via%3Dihub">broad range</a> of factors that can influence your current level of financial stress. These include contextual and personal ones. Contextual factors are societal-level influences on the current financial landscape. These include rates of economic growth, market performance, governmental and political policy, and distribution of wealth. These factors may vary across cultures and countries. Personal factors contributing to stress are unique to each person. For example, demographic characteristics such as age, gender, education and ethnic group may influence someone’s access to financial resources. Other personal factors that can affect financial stress are financial literacy and practices, personality traits that influence behaviour and perceptions, and major life events with financial implications (such as marriage, having a child, or retiring). <h2>The health impacts can be severe</h2> High levels of financial stress can <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0264041">impact</a> people’s wellbeing, raising levels of psychological distress, anxiety and depression. <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0264041">A review</a> found clear evidence for a link between financial stress and depression, and that the risk for depression was greatest for people on low incomes. A <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8806009/">large survey</a> of adults in the United States also found that greater financial worries were associated with more psychological distress. This was especially the case for people who were unmarried, unemployed, had lower income levels and who were renters. So people who are more vulnerable financially – in an objective sense – are also most likely to experience negative psychological effects from financial stress. However, the perception of your financial situation matters here too. In <a href="https://www.cambridge.org/core/journals/ageing-and-society/article/abs/crossnational-insights-into-the-relationship-between-wealth-and-wellbeing-a-comparison-between-australia-the-united-states-of-america-and-south-korea/AA524919C71EC125CFEA644CD209D3D5">one study</a> of older adults, including Australians, it was not just someone’s financial situation that was linked to their wellbeing, but also how satisfied people were with their wealth. Severe financial stressors, such as being forced to sell your home if unable to meet mortgage payments, can affect <a href="https://reader.elsevier.com/reader/sd/pii/S0277953616302957?token=F74F2A5518F51A8356DD0109748E1DD5633480DC58E2A77EF71BFE7ABAA503B61465634336A38BB9CC623E3872429D32&originRegion=us-east-1&originCreation=20230315042306">both</a>psychological and physical health. <h2>What can I do about it?</h2> While we can’t change the broader financial landscape or some aspects of our financial situation, there are some simple ways to help reduce financial stress and its impacts. 1. Take small steps Try to identify elements of your finances you can improve and act on some of them, even if they are small steps. This may include creating and following a budget, cutting some extra costs, applying for available financial assistance, getting quotes for more affordable utilities or insurance, or contemplating a career change. Even little changes can improve your financial state over time. Taking action in a difficult situation can improve wellbeing by giving you a greater sense of agency. 2. Check your take on the situation Examine your perspective. Are you often seeing the negative aspects of your situation but ignoring the positive ones? Are you worrying a lot about very unlikely catastrophes far off in the future? It’s worth checking whether your perceptions about your financial situation are accurate and balanced. 3. Don’t be too hard on yourself Your financial state does not reflect your value as a person, and <a href="https://pubmed.ncbi.nlm.nih.gov/28903640/">over-identifying</a> with your financial status can lead to further stress. Financial difficulties are the result of many factors, only some of which are under your control. Reminding yourself that your finances do not define you as a person can reduce feelings of sadness, shame or guilt. 4. Take care of yourself It’s draining dealing with ongoing financial stress. So focus on self-care and coping strategies that have helped you with past stressors. This may mean taking some time out to relax, deep breathing or meditation, <a href="https://theconversation.com/stress-is-a-health-hazard-but-a-supportive-circle-of-friends-can-help-undo-the-damaging-effects-on-your-dna-171607">talking with others</a> and doing some things for fun. Giving yourself permission to take this time can improve your mood, perspective and wellbeing. 5. Ask for help If you are struggling financially or psychologically, seek help. This may take the form of financial advice or assistance to reduce financial difficulties. If you notice yourself feeling persistently down, anxious, or hopeless, reach out to friends or family and get help from a mental health professional.

4 surprising ways your height affects your health

How tall you are, to some extent, affects how you experience the world. You may always bump your head on the door frame, or get your feet trodden on in crowds or just find it hard to buy the right shoes. All these little things affect our wellbeing, but science has shown there are also larger factors at play. Here are four surprising ways your height affects your health. 1. Cancer risk Cancer is caused by abnormal cells multiplying out of control, so, more cells might mean more opportunity for a cancer-causing mutation. That explanation plays out in the research on hormone-related cancers, such as breast, ovarian and prostate, which are more common among the height-gifted. 2. Heart disease and diabetes Since greater height might allow larger, more robust blood vessels, being shorter can make you more prone to heart disease and diabetes. 3. Organ transplants It may not be something you’ve ever had to think about, but organs are not one-size-fits-all. Research suggests that people five feet, three inches or shorter currently wait longer on organ lists and are more likely to die in the process. There have been suggestions that surgeons could potentially “downsize” available lungs to fit shorter patients. 4. Injury This one is simple really – if a tall person falls, they have longer to go before hitting the ground than a smaller person. As a result, their injuries are often worse. Lanky people may also be crippled by slower reactions times since their nerve impulses have farther to travel. How have you found your height to affect your health? Let us know in the comments below.

How the pandemic affected our approach to reading and interpretation of books

During the pandemic, reading took on new meaning. People turned to books for comfort. Some read to confront difficult issues, especially following the murder of George Floyd in 2020. Others used reading as a way to care for their children in locked-down houses. <a href="https://www.theguardian.com/books/2020/mar/25/book-sales-surge-self-isolating-readers-bucket-list-novels" target="_blank" rel="noopener">Sales figures and lending data</a> showed a huge spike in people buying and borrowing books. We wanted to follow the stories of real readers and <a href="https://global.oup.com/academic/product/reading-novels-during-the-covid-19-pandemic-9780192857682?q=reading%20novels%20during%20the%20pandemic&lang=en&cc=dk" target="_blank" rel="noopener">our new book</a> uses a rare combination of literary analysis and qualitative interviewing to capture these dynamics of reception. While many commentators at the beginning of the pandemic <a href="https://www.refinery29.com/en-us/2020/03/9581961/long-books-to-read-in-quarantine" target="_blank" rel="noopener">endorsed reading</a> as a straightforward way to relax, our readers showed that the practice morphed and took on new forms and meanings. Based on hundreds of survey responses and hours of reader interviews from Denmark and the UK, the study makes the interpretation of literature something dynamic and ongoing. And it suggests that readers themselves are agents of meaning, even in the case of novels that seem the most stable in our culture. Reading during the pandemic showed how books and their meanings change. Novels that we think of as settled in their significance acquire new meaning as they are read under unfolding conditions, exposed to the vagaries of history. In our research we show how Albert Camus’s The Plague became an unlikely hit in 2020, how the affordances of Sally Rooney’s romantic fiction seemed suddenly to apply to the lovers unable to meet, and how long novels that had intimidated pre-pandemic readers became lifelines in their heft. <h2>Tricky reading</h2> For many people, reading became more difficult during this time. Far from giving everyone uninterrupted time to attend to long novels by authors like Tolstoy, lockdown exacerbated the separations and challenges of everyday life. Take Jane Eyre, a novel that many readers picked up during lockdown because it was on their shelves. Suddenly, this classic seemed to be a novel about a woman locked in small rooms and living through a cholera epidemic. Many also took it up under conditions that overlapped directly with the book’s scenes of homeschooling. One respondent called Phoebe, for instance, deliberately avoided rereading Jane Eyre for these reasons. Charlotte Brontë’s classic novel of loneliness and love was, in 2020, “too creepy”. The story of Jane being locked up made her feel unsafe while she lived alone through lockdown in the confines of her own room. Another interviewee, Alexandra, was troubled by the idea of reading Hilary Mantel’s bestseller The Mirror and the Light, explaining: <blockquote> I knew that I would be saying goodbye to Sir Thomas Cromwell […] I looked at it and I thought, what if I die before I get to the end of this? It will be the most unsatisfactory experience. </blockquote> Rather than sizing up the third part of Mantel’s intimate portrayal of the life of Thomas Cromwell as offering the ideal opportunity for narrative immersion, Alexandra viewed the very thickness of the book as problematic. Her intense fear of death in the pandemic and expectation of Cromwell’s literary demise converge on the length of narrative, which stretches into a future that had become harder to face. <h2>Slipperiness of time</h2> For the reader caught up in a global pandemic, a novel like The Plague, Albert Camus’s famous story of a town suffering a deadly virus, reads differently than it usually would for, say, the school student of French literature. One interviewed reader, for instance, discussed the novel’s temporal slipperiness. Normally, of course, the very lack of measurable time would suggest the novel as an allegory – untied to a particular time, a warning of dark political forces turning up and spreading at any moment. But in 2020, when time <a href="https://theconversation.com/a-philosophical-idea-that-can-help-us-understand-why-time-is-moving-slowly-during-the-pandemic-151250" target="_blank" rel="noopener">felt like it was moving oddly</a> The Plague’s confused sense of time felt realistic, as if it were mimicking our lived experience of a pandemic. <figure></figure> Yet, it would be a mistake to assume all readers suddenly ditched allegory for realism or real-life correspondence. As Kirsten, a Danish woman in her 30s, explained: <blockquote> I ended up buying The Plague because I was more interested in the metaphorical portrait of the occupation (of France by the Nazis) than in what epidemics do to a society. </blockquote> By following real readers, our study provides a snapshot of a phenomenal moment in modern history and shows the movement of readers between new purchases and books long kept in their collections. By exploring these varied experiences, we investigated the larger question of how the consumption of novels depends on and shapes people’s experience of non-work time, providing a specific lens through which to examine the experience of reading more generally. Perhaps most importantly, it demonstrates the dynamic process of reading and the ways in which books change depending on where and when they are read and by whom.

Robert Irwin gets candid about health issue affecting his family

Robert Irwin has opened up about how dementia has affected his family. The 19-year-old appeared on The Project as a co-host when they began discussing dementia - a disorder that can affect thinking, memory and behaviour. The son of the late Steve Irwin said that he doesn’t think there’s anyone living who hasn’t encountered a person with dementia. “I think there’s no-one living who hasn’t encountered someone or has a loved one who has experienced this,” he said. “I know my grandfather on my mum’s side had a form of dementia and a lot of family friends have had that as well and it’s just, it’s devastating. “Someone you love, someone you’re close to you see going through that and just not being able to relive and enjoy the moments they had it’s heartbreaking. “But I guess it just reminds you you’ve got to spend every second with the people you love and really surround yourself with love and light and hopefully this is light at the end of the tunnel for a safe way for people to stop this.” <blockquote class="twitter-tweet"> Alzheimer’s is the merciless brain condition that slowly erodes the cognitive function and precious memories of thousands of Australians. But, a revolutionary new treatment could turn the tide in the fight against the disease. <a href="https://twitter.com/hashtag/TheProjectTV?src=hash&ref_src=twsrc%5Etfw">#TheProjectTV</a> <a href="https://t.co/IVuMloeUN5">pic.twitter.com/IVuMloeUN5</a> — The Project (@theprojecttv) <a href="https://twitter.com/theprojecttv/status/1599316365369901058?ref_src=twsrc%5Etfw">December 4, 2022</a></blockquote> Robert went on to say that he will continuing his father’s legacy and how proud he is to be a part of it, speaking about a recent performance with the Wiggles. “The Wiggles are just legendary, my dad actually did a really fun collaboration project with them at Australia Zoo way back in the day 20 years ago,” he said. “So we’ve worked with them for a long time so the fact all of the original Wiggles came back to support our charity Wildlife Warriors means the world. “Dad set this up as a way to support wildlife conservation here in Australia and on the global stage and a night like that just makes us realise his legacy is alive and thriving and it’s the honour of a lifetime to keep that going.” Robert recently celebrated his <a href="https://oversixty.com.au/lifestyle/family-pets/robert-irwin-turns-19-in-style" target="_blank" rel="noopener">19th birthday</a> at Australia Zoo with his mother and rumoured girlfriend, Scarlett Buckley, who is the niece of the late Heath Ledger.

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

Think of a time when you felt vulnerable. Perhaps you were in a hospital corridor, or an exam hall, about to be tested. Now, focus on the building you were in. What if, without you knowing, the design of that space was affecting you? We study <a href="https://psychology.org.au/community/advocacy-social-issues/environment-climate-change-psychology/psychologys-role-in-environmental-issues/what-is-environmental-psychology" target="_blank" rel="noopener">environmental psychology</a>, a growing field of research investigating the relationship between humans and the external world. This includes natural, and human-made environments, such as buildings. Researchers could just ask people what they feel when inside a building – how pleasant or unpleasant they feel, the intensity of that feeling, and how in control they feel. But we use neuroscience to see how the brain is stimulated when inside a building. The idea is for people to one day use that information to design better buildings – classrooms that help us concentrate, or hospital waiting rooms that reduce our anxiety. Why study buildings this way? We spend <a href="https://www.health.vic.gov.au/chief-health-officer/healthy-indoor-environments" target="_blank" rel="noopener">at least 80% of our lives</a> inside buildings. So it is critical we understand whether the buildings we occupy are affecting our brain and body. Buildings – hospitals, schools, offices, homes – are often complex. They can have various contents (fixtures, fittings and objects), levels of comfort (such as the light, sound, and air quality). Other people occupy the space. There are also a range of design characteristics we can notice inside a building. These include colour (wall paint, chair colour), texture (carpet tiles, timber gym floor), geometry (curved walls or straight, angular ones), and scale (proportions of height and width of a room). What did we do? We wanted to see what effect changing some of these characteristics had on the brain and body. So we asked participants to sit in the middle of a virtual-reality (VR) room for 20 minutes. We designed the room with a door (to show height) and chair (to show depth), keeping it empty of other cues that might influence people. We modelled the room using dimensions set by the local building code. Other studies have compared <a href="https://doi.org/10.1016/j.jenvp.2019.101344" target="_blank" rel="noopener">complex environments</a>, which are more realistic to everyday life. But we chose to use a simple VR room so we could understand the impact of changing one characteristic at a time. To measure brain activity, we used a technique called electroencephalography. This is where we placed electrodes on the scalp to measure electrical activity as brain cells (neurons) send messages to each other. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/485808/original/file-20220921-13-7qqec9.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/485808/original/file-20220921-13-7qqec9.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/485808/original/file-20220921-13-7qqec9.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=429&fit=crop&dpr=1 600w, https://images.theconversation.com/files/485808/original/file-20220921-13-7qqec9.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=429&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/485808/original/file-20220921-13-7qqec9.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=429&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/485808/original/file-20220921-13-7qqec9.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=539&fit=crop&dpr=1 754w, https://images.theconversation.com/files/485808/original/file-20220921-13-7qqec9.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=539&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/485808/original/file-20220921-13-7qqec9.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=539&fit=crop&dpr=3 2262w" alt="Fitting cap of electrodes" /></a><figcaption>Participants wore a cap covered in electrodes to detect electrical activity in the brain. Donna Squire, Author provided</figcaption></figure> We also monitored the body by measuring heart rate, breathing and sweat response. This could reveal if someone could detect a change to the environment, without being consciously aware of that change. Lastly, we asked participants to report their emotions to understand if this matched their brain and body responses. What did we find? We published a series of studies looking at the impact of room size and colour. Making the room bigger resulted in brain activity usually linked to <a href="https://doi.org/10.1523/ENEURO.0104-22.2022" target="_blank" rel="noopener">attention and cognitive performance</a>. This is the type of brain activity we would see if you were doing a crossword, your homework or focusing on a tricky report you were writing for work. A blue room resulted in brain activity associated with <a href="https://doi.org/10.1111/psyp.14121" target="_blank" rel="noopener">emotional processing</a>. This is the pattern we’d typically see if you were looking at something that you felt positive about, such as a smiling face, or a scenic sunset. Changing the size and colour of a room also changed <a href="https://doi.org/10.1002/hbm.26061" target="_blank" rel="noopener">brain network communication</a>. This is when different parts of the brain “talk” to one another. This could be communication between parts of the brain involved in seeing and attention, the type of communication needed when viewing a complex scene, such as scanning a crowded room to spot a friend. The rooms also changed the participants’ autonomic response (their patterns of breathing, heart activity and sweating). <hr /> <figure><iframe title="YouTube video player" src="https://www.youtube.com/embed/dPHOQvLOCD4" width="100%" height="400" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption>Your brain and body give away what you feel and think about different rooms, even if you can’t tell us yourself.</figcaption></figure> <hr /> Despite these brain and body responses, we found no change in what participants told us about their emotions in each of these different conditions. This suggests the need to shift from just asking people about their emotions to capturing effects they may not be consciously perceive or comprehend. What does this mean for designing buildings? This work tells us that characteristics of buildings have an impact on our brains and our bodies. Our next steps include testing whether a larger room affects brain processes we use in everyday life. These include working memory (which we’d use to remember our shopping list) and emotion recognition (how we recognise what different facial expressions mean). This will enable us to understand if we can design spaces to optimise our cognitive performance. We also want to understand the implications on a wider population, including people who may be experiencing poor mental health, or diagnosed with an underlying condition where the environment may have a larger impact on their response. This will help us to understand if we can change our built environment for better health and performance. Why is this important? Architects have long claimed buildings <a href="https://theconversation.com/build-me-up-how-architecture-can-affect-emotions-22950" target="_blank" rel="noopener">affect our emotion</a>. But there has been a lack of brain-based evidence to back this. We hope our work can help shape building planning and design, to support the brain processes and emotions we might require under different circumstances.<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/189797/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> Written by Isaballa Bower.

How can your lifestyle affect your memory?

Did you know that dementia is now the second leading cause of death in Australia? The numbers of people being diagnosed with dementia are increasing every year, instead of decreasing. Many families are now affected by dementia with having either a parent, family member or friend being diagnosed. Did you know that memory problems are one of the earliest symptoms of Alzheimer’s disease/dementia? So it makes sense that if memory problems are one of the earliest symptoms of dementia, you should not be ignoring those memory problems when they occur. They are signals for you to be proactive, find out why they are happening, and not wait till they get worse, because time is of the utmost importance. Our modern lifestyle plays a huge role as to why dementia numbers are increasing. I have found in my research so many causes of memory problems that I have put them into two categories – medical causes and lifestyle causes. Some of these causes may be able to be treated which may help to improve your memory. Here are two examples of lifestyle causes of memory problems that you should be aware of: 1. Stress Stress is one of the major causes of memory problems. When we are stressed and produce the stress hormone cortisol, thousands of neurons (brain cells) can die off. When we are highly stressed, we seem to think less clearly and tend to forget even simple things. Too much cortisol causes a decline in the daily function of your brain. It also robs your brain of glucose, which is its only source of fuel. Excessive cortisol also affects your brain’s chemical messengers – your neurotransmitters – which carry your thoughts from one brain cell to the next. Many scientists now believe that too much exposure to stress can actually shrink your brain. 2. Foods to Avoid These are the ingredients found in packaged food products. These particular ingredients have been added to many packaged food products and ‘diet’ drinks found on the supermarket shelves. One main ingredient to look out for and avoid as much as possible is aspartame, an artificial sweetener. Aspartame is an excito-toxin which may cause brain cells to become over-stimulated. If they become too over-stimulated this may cause brain cells to die. Check out the packaged food products and drinks in your pantry and look at the ingredient list for Aspartame (950) or (951) and avoid them. Have you been getting a bit forgetful occasionally and wondered why this may be happening? You may be consuming ‘diet’ drinks as part of your lifestyle because you want to cut back on your sugar intake or are watching your weight. But these ‘diet’ drinks may be the cause of your memory problems. Try to reduce the amount of ‘diet’ drinks you consume. As a result, you may notice an improvement in your memory. <a href="https://www.smartbrainhealthcentre.com.au/">Louise Hallinan</a> is the international award-winning author of Smart Brain, Healthy Brain, a natural medicine practitioner and founder of the Smart Brain Health Centre which specialises in helping Baby Boomers and Generation X mothers avoid the risk of dementia.

Unpaid and unequal: women’s extra workload affects mental wellbeing

Women do the bulk of unpaid domestic work globally and the added burden has an impact on their mental health – but surprisingly there’s little independent empirical research about this. Now, there is data, which shows the double burden of paid and unpaid work results in increased depressive or psychological distress for women as unpaid labour increases. Researchers at the University of Melbourne reviewed the evidence for the gendered nature of unpaid work and consequences for mental health among employed adults, <a href="https://www.thelancet.com/journals/lanpub/article/PIIS2468-2667(22)00160-8/fulltext" target="_blank" rel="noreferrer noopener">publishing</a> their results in Lancet Public Health. Public health researcher and lead author, Jen Ervin, says the research showed women were uniformly doing more unpaid work across every geographical and time setting. “What our review tells us is that, in addition to the economic penalty women experience carrying out most of the world’s unpaid labour load, there is a troubling mental health cost as well,” she says. While further research is needed, Ervin says the most widely acknowledged explanation for the impact on mental health is that the combined paid and unpaid workload triggers stress-related pathways. It also reduces time for activities known to be protective for mental health such as sleep, leisure and physical activity. The findings won’t come as a surprise to many, especially women, she says. Indeed. The study follows <a href="https://findanexpert.unimelb.edu.au/news/47524-yet-again--the-census-shows-women-are-doing-more-housework.-now-is-the-time-to-invest-in-interventions" target="_blank" rel="noreferrer noopener">census data</a> confirming (once again) that Australian women do more hours of unpaid housework than men. And <a href="https://cew.org.au/2022-cew-census-an-urgent-wakeup-call-ceo-gender-balance-100-years-away/" target="_blank" rel="noreferrer noopener">another report</a> this week commissioned by Chief Executive Women indicating caring responsibilities in the pandemic held back progress on women’s workforce participation and leadership. For what seems like an intractable problem, what can be done to change things? Ervin says, “we believe that policies such as universal childcare and normalising flexible working arrangements and extended paternity leave for men can help in shifting the dial and driving greater gender equality in the division of unpaid labour and unpaid care. <div class="newsletter-box"> <div id="wpcf7-f6-p205326-o1" class="wpcf7" dir="ltr" lang="en-US" role="form"> <form class="wpcf7-form mailchimp-ext-0.5.62 spai-bg-prepared init" action="/health/womens-unpaid-work-and-mental-health/#wpcf7-f6-p205326-o1" method="post" novalidate="novalidate" data-status="init"> <input class="wpcf7-form-control wpcf7-text referer-page" name="referer-page" type="hidden" value="https://cosmosmagazine.com/health/" data-value="https://cosmosmagazine.com/health/" aria-invalid="false" /> </form> </div> </div> “Some of these measures will also aid and facilitate the harder task of shifting some of the outdated attitudes and beliefs around labour division.” It’s important to note many men are taking a more active role in childcare and housework. But men can be limited in doing so by factors such as inflexible workplace arrangements or social stigma, she says. The University of Melbourne research focussed on employed adults, the ‘double burden’ effect of combining paid work with unpaid work, and how this subsequently creates issues of overload and time poverty. It found substantial gender differences. Of the 14 studies reviewed for the article – totalling more than 66,800 participants worldwide – five examined unpaid labour (inclusive of care), nine examined housework time and, of these, four also examined childcare. Overall, in 11 of the 14 studies, women self-reported increased depressive or psychological distress symptoms with increasing unpaid labour demands. For men, only three out of a possible 12 studies reported any negative association. An aspect not captured in the current review, Ervin says, is the difference in the gendered allocation of household tasks. For example, men often do less-time-sensitive outdoor or maintenance tasks such as mowing the lawn or cleaning the gutters. These jobs aren’t as time-pressured as feeding a hungry child or driving them to an appointment. And while more difficult to measure, <a href="https://www.tandfonline.com/doi/abs/10.1080/13668803.2021.2002813?journalCode=ccwf20" target="_blank" rel="noreferrer noopener">other research</a> shows women are also often carrying more of the mental load of household labour. Unfortunately, Australia is lagging behind many other countries when it comes to key gender equality indicators such as unpaid labour division, Ervin says. This week a <a href="https://cew.org.au/2022-cew-census-an-urgent-wakeup-call-ceo-gender-balance-100-years-away/" target="_blank" rel="noreferrer noopener">report</a> commissioned by Chief Executive Women drew attention to the lack of progress made by Australia’s top companies in appointing women to leadership roles. The report, prepared by management consultants Bain & Company, says 73% of executive roles in ASX300 companies are held by men, and 85% of line management roles. The report says COVID-19 set back women’s workforce participation, as they took on the bulk of the increased caring responsibilities. This is consistent with <a href="https://findanexpert.unimelb.edu.au/news/47524-yet-again--the-census-shows-women-are-doing-more-housework.-now-is-the-time-to-invest-in-interventions" target="_blank" rel="noreferrer noopener">findings</a> from other University of Melbourne research showing the “catastrophic” impact of the pandemic on women’s lives, especially for mothers. Restrictions such as school closures and remote learning added to the domestic workload for everyone, but the gender gap remained. Women, more often than men, reduced their paid work to meet the increased demands. The Murdoch Children’s Research Institute also <a href="https://cosmosmagazine.com/health/mental-health-maternal-lockdown/" target="_blank" rel="noreferrer noopener">reported</a> maternal wellbeing was profoundly impacted by the pandemic, finding a third of women experienced clinically significant mental health problems during Victoria’s second lockdown, with ongoing fatigue and parenting stress.  <img id="cosmos-post-tracker" style="opacity: 0; height: 1px!important; width: 1px!important; border: 0!important; position: absolute!important; z-index: -1!important;" src="https://syndication.cosmosmagazine.com/?id=205326&title=Unpaid+and+unequal%3A+women%26%238217%3Bs+extra+workload+affects+mental+wellbeing" width="1" height="1" />  <div id="contributors"> <a href="https://cosmosmagazine.com/health/womens-unpaid-work-and-mental-health/" target="_blank" rel="noopener">This article</a> was originally published on <a href="https://cosmosmagazine.com" target="_blank" rel="noopener">Cosmos Magazine</a> and was written by <a href="https://cosmosmagazine.com/contributor/petra-stock" target="_blank" rel="noopener">Petra Stock</a>.
