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

<p><em><a href="https://theconversation.com/profiles/jane-andrew-10314">Jane Andrew</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/dr-penelope-bowyer-pont-1550191">Dr Penelope Bowyer-Pont</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>, and <a href="https://theconversation.com/profiles/max-baker-25553">Max Baker</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>More of our personal data is now collected and stored online than ever before in history. The rise of data breaches should unsettle us all.</p> <p>At an individual level, data breaches can compromise our privacy, cause harm to our finances and mental health, and even enable identity theft.</p> <p>For organisations, the repercussions can be equally severe, often resulting in major financial losses and brand damage.</p> <p>Despite the increasing importance of protecting our personal information, doing so remains fraught with challenges.</p> <p>As part of a <a href="http://www.doi.org/10.25910/psq3-q365">comprehensive study</a> of data breach notification practices, we interviewed 50 senior personnel working in information security and privacy. Here’s what they told us about the multifaceted challenges they face.</p> <h2>What does the law actually say?</h2> <p>Data breaches occur whenever personal information is accessed or disclosed without authorisation, or even lost altogether. <a href="https://www.abc.net.au/news/2024-06-20/optus-hack/104002682">Optus</a>, <a href="https://www.abc.net.au/news/2022-11-09/medibank-data-release-dark-web-hackers/101632088">Medibank</a> and <a href="https://www.afr.com/technology/canva-criticised-after-data-breach-exposed-139m-user-details-20190526-p51r8i">Canva</a> have all experienced high-profile incidents in recent years.</p> <p>Under Australia’s <a href="https://www8.austlii.edu.au/cgi-bin/viewdb/au/legis/cth/consol_act/pa1988108/">privacy laws</a>, organisations aren’t allowed to sweep major cyber attacks under the rug.</p> <p>They have to notify both the regulator – the Office of the Australian Information Commissioner (OAIC) – and any affected individuals of breaches that are likely to result in “<a href="https://www8.austlii.edu.au/cgi-bin/viewdb/au/legis/cth/consol_act/pa1988108/#:%7E:text=Whether%20access%20or%20disclosure%20would%20be%20likely%2C%20or%20would%20not%20be%20likely%2C%20to%20result%20in%20serious%20harm%2D%2Drelevant%20matters%20%C2%A0">serious harm</a>”.</p> <p>But according to the organisational leaders we interviewed, this poses a tricky question. How do you define serious harm?</p> <p>Interpretations of what “serious harm” actually means – and how likely it is to occur – vary significantly. This inconsistency can make it impossible to predict the specific impact of a data breach on an individual.</p> <p>Victims of domestic violence, for example, may be at increased risk when personal information is exposed, creating harms that are difficult to foresee or mitigate.</p> <h2>Enforcing the rules</h2> <p>Interviewees also had concerns about how well the regulator could provide guidance and enforce data protection measures.</p> <p>Many expressed a belief the OAIC is underfunded and lacks the authority to impose and enforce fines properly. The consensus was that the challenge of protecting our data has now outgrown the power and resources of the regulator.</p> <p>As one chief information security officer at a publicly listed company put it:</p> <blockquote> <p>What’s the point of having speeding signs and cameras if you don’t give anyone a ticket?</p> </blockquote> <p>A lack of enforcement can undermine the incentive for organisations to invest in robust data protection.</p> <h2>Only the tip of the iceberg</h2> <p>Data breaches are also underreported, particularly in the corporate sector.</p> <p>One senior cybersecurity consultant from a major multinational company told us there is a strong incentive for companies to minimise or cover up breaches, to avoid embarrassment.</p> <p>This culture means many breaches that should be reported simply aren’t. One senior public servant estimated only about 10% of reportable breaches end up actually being disclosed.</p> <p>Without this basic transparency, the regulator and affected individuals can’t take necessary steps to protect themselves.</p> <h2>Third-party breaches</h2> <p>Sometimes, when we give our personal information to one organisation, it can end up in the hands of another one we might not expect. This is because key tasks – especially managing databases – are often outsourced to third parties.</p> <p>Outsourcing tasks might be a more efficient option for an organisation, but it can make protecting personal data even more complicated.</p> <p>Interviewees told us breaches were more likely when engaging third-party providers, because it limited the control they had over security measures.</p> <p>Between July and December 2023 in Australia, there was an increase of <a href="https://www.oaic.gov.au/privacy/notifiable-data-breaches/notifiable-data-breaches-publications/notifiable-data-breaches-report-july-to-december-2023">more than 300%</a> in third-party data breaches compared to the six months prior.</p> <p>There have been some highly publicised examples.</p> <p>In May this year, many Clubs NSW customers had their personal information potentially <a href="https://www.rimpa.com.au/resource/more-than-a-million-australian-data-records-potentially-exposed-in-nsw-club-and-pub-data-breach.html#:%7E:text=Outabox%2C%20the%20IT%20services%20provider,and%20has%20notified%20law%20enforcement">breached</a> through an attack on third-party software provider Outabox.</p> <p>Bunnings suffered a <a href="https://australiancybersecuritymagazine.com.au/bunnings-customer-data-compromised/">similar breach</a> in late 2021, via an attack on scheduling software provider FlexBooker.</p> <h2>Getting the basics right</h2> <p>Some organisations are still struggling with the basics. Our research found many data breaches occur because outdated or “legacy” data systems are still in use.</p> <p>These systems are old or inactive databases, often containing huge amounts of personal information about all the individuals who’ve previously interacted with them.</p> <p>Organisations tend to hold onto personal data longer than is legally required. This can come down to confusion about data-retention requirements, but also the high cost and complexity of safely decommissioning old systems.</p> <p>One chief privacy officer of a large financial services institution told us:</p> <blockquote> <p>In an organisation like ours where we have over 2,000 legacy systems […] the systems don’t speak to each other. They don’t come with big red delete buttons.</p> </blockquote> <p>Other interviewees flagged that risky data testing practices are widespread.</p> <p>Software developers and tech teams often use “production data” – real customer data – to test new products. This is often quicker and cheaper than creating test datasets.</p> <p>However, this practice exposes real customer information to insecure testing environments, making it more vulnerable. A senior cybersecurity specialist told us:</p> <blockquote> <p>I’ve seen it so much in every industry […] It’s literally live, real information going into systems that are not live and real and have low security.</p> </blockquote> <h2>What needs to be done?</h2> <p>Drawing insights from professionals at the coalface, our study highlights just how complex data protection has become in Australia, and how quickly the landscape is evolving.</p> <p>Addressing these issues will require a multi-pronged approach, including clearer legislative guidelines, better enforcement, greater transparency and robust security practices for the use of third-party providers.</p> <p>As the digital world continues to evolve, so too must our strategies for protecting ourselves and our data.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/236681/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/jane-andrew-10314">Jane Andrew</a>, Professor, Head of the Discipline of Accounting, Governance and Regulation, University of Sydney Business School, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/dr-penelope-bowyer-pont-1550191">Dr Penelope Bowyer-Pont</a>, Researcher, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>, and <a href="https://theconversation.com/profiles/max-baker-25553">Max Baker</a>, Associate professor, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Who dies in a heat wave? How to help protect the vulnerable in our communities

<p><em><a href="https://theconversation.com/profiles/myles-david-sergeant-1542267">Myles David Sergeant</a>, <a href="https://theconversation.com/institutions/mcmaster-university-930">McMaster University</a></em></p> <p>Extreme heat is a silent killer.</p> <p>From time to time, we hear about shocking cases of <a href="https://www.theguardian.com/world/2023/sep/24/football-player-heat-deaths-athlete">football players</a> and other athletes who die suddenly while exerting themselves on hot days. Those deaths are certainly tragic, but statistically they are very rare.</p> <p>Most deaths from extreme heat <a href="https://www.epa.gov/climate-indicators/climate-change-indicators-heat-related-deaths">are in older people</a>, who frequently die alone inside their homes. They often die slowly, as the heat creeps up to and sometimes past body temperature, especially when heat domes park themselves over cities and keep the temperature high all day and all night. When such deaths happen, they rarely make the news.</p> <p>Of all the climate change disasters our world is already experiencing, heat is the top killer, <a href="https://library.wmo.int/viewer/68500/download?file=1335_WMO-Climate-services-Health_en.pdf&amp;type=pdf&amp;navigator=1">as the World Meteorological Organization reported</a>. The planet was more than <a href="https://www.theguardian.com/environment/article/2024/jul/08/temperatures-1-point-5c-above-pre-industrial-era-average-for-12-months-data-shows">1.5 C above the pre-industrial baseline</a> for 12 consecutive months from July 2023 to June 2024. In July this year, we saw the hottest three days ever on record, prompting <a href="https://www.un.org/sg/en/content/sg/press-encounter/2024-07-25/secretary-generals-press-conference-extreme-heat">a special statement from United Nations Secretary-General Antonio Guterres</a>.</p> <h2>Health risks and heat</h2> <p><a href="https://www.ncbi.nlm.nih.gov/books/NBK499843/">Our bodies are made to dump excess heat</a> when we are too warm, but that process goes into reverse when the air is warmer than our core temperature. Our other main defence, sweating, doesn’t help when humidity saturates the air, making it impossible for our own moisture to evaporate.</p> <p>For the frail and elderly, who are more likely to be labouring with heart troubles, COPD or other challenges, simply sitting still in a heat wave requires an effort equivalent to walking on a treadmill. The effort is not great, but it is <a href="https://doi.org/10.1016/j.cjco.2021.10.002">steady and relentless</a>. It exhausts the body, sometimes to the <a href="https://doi.org/10.1016/S2542-5196(22)00117-6">point of no return</a>.</p> <p>Tracking heat-related deaths is challenging, and it’s changing as authorities become more aware of heat as a contributing or underlying factor to deaths by other causes. <a href="https://doi.org/10.2105/AJPH.2006.100081">A paper published by the <em>American Journal of Public Health</em></a> points out that the 1995 heat wave in Chicago likely contributed to hundreds more deaths than had first been attributed to heat itself.</p> <h2>Who is at risk?</h2> <p>Many people lack air conditioning or a way to get to a place that has it, such as a library, recreation centre or shopping mall. As a result, too many people in cities are forced to <a href="https://wmo.int/publication-series/2023-state-of-climate-services-health">endure long waves of heat</a> — waves that are occurring more frequently, lasting longer, and reaching higher temperatures — in a trend that appears set to continue getting worse.</p> <p>Air conditioning, <a href="https://www.lpm.org/news/2015-07-24/the-history-of-movie-theaters-and-air-conditioning-that-keeps-film-lovers-cool">once a luxury that drew people to summertime movie theatres on hot nights</a>, has become a necessity. Increasingly, it is also a legal requirement, as cities pass bylaws requiring landlords not to allow the temperature in their tenants’ quarters to rise above a certain level. Toronto has <a href="https://www.toronto.ca/home/311-toronto-at-your-service/find-service-information/article/?kb=kA06g000001xvbiCAA">such a bylaw</a> for rental units that have air conditioning available, capping indoor temps at 26 C between June 2 and Sept. 14.</p> <p>Such laws recognize the vulnerability of tenants who lack control over the temperature in their rental units, making heat death an especially urban tragedy, as confirmed in <a href="https://www150.statcan.gc.ca/n1/en/pub/82-003-x/2024006/article/00001-eng.pdf?st=e6jLNMuq">a recent Statistics Canada study</a> between 2000 and 2020. Deaths from extreme heat were more likely in cities with a higher percentage of renter households.</p> <p>During a single week-long heat wave in June 2021 — the year after the period captured in the Statistics Canada study — <a href="https://www.cbc.ca/news/canada/british-columbia/bc-heat-dome-sudden-deaths-570-1.6122316">B.C.’s chief coroner found that 570 people died from heat-related causes</a> — 79 per cent of them were seniors.</p> <h2>Taking action at the community level</h2> <p>From this Global North perspective, the community members who are most likely to die from extreme heat included:</p> <ul> <li>Those over 65</li> <li>Those with more than one chronic condition (including hypertension, mental health, diabetes, heart disease, lung disease)</li> <li>Socially disadvantaged populations in our communities</li> <li>Those with mobility issues</li> <li>Those experiencing social isolation (living alone)</li> <li>Tenants with lack of air conditioning</li> <li>Those living in an urban heat island</li> </ul> <p>This problem is not going away.</p> <p>Some of the <a href="https://www.intactcentreclimateadaptation.ca/wp-content/uploads/2022/06/UoW_ICCA_2022_04-Irreversible-Extreme-Heat.pdf">actions we can take</a> to protect our most vulnerable community members include:</p> <ul> <li>Increase awareness that excessive heat is not merely uncomfortable, but dangerous.</li> <li>Make sure people are warned about impending heat waves.</li> <li>Advocate for everyone to have access to air conditioning.</li> <li>Check on and support people who live alone, especially those with no air conditioning.</li> <li>Invite people over if you have air conditioning, or help them get to community cooling stations.</li> <li>Help vulnerable people who do not have air conditioning to improvise, by freezing wet cloths, for example, to take out and hang around their necks.

Are cats good for our health?

<p><em><a href="https://theconversation.com/profiles/susan-hazel-402495">Susan Hazel</a>, <a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a></em></p> <p>Cats have lived with humans for <a href="https://www.nature.com/articles/s41559-017-0202">thousands of years</a>. And <a href="https://www.bbc.com/future/article/20240923-100-year-old-cat-memes-that-predate-the-internet">long before</a> cat memes and viral <a href="https://theconversation.com/tiktok-says-orange-cats-are-dumb-and-tortoiseshell-cats-have-an-attitude-but-how-true-is-that-218033">TikToks</a> took over the internet, they’ve been comforting us with their purrs and making us laugh with their weird antics.</p> <p>But what does the research say – are cats good for us?</p> <p>Living with a cat can have a profound – and sometimes surprising – effect on our physical and mental health. Still, living with cats is not without risks.</p> <h2>Part of the family</h2> <p>You may have heard cats don’t have owners, they have “staff”. In fact, multiple studies show the humans who live with them feel more like beloved relatives.</p> <p>In a <a href="https://www.mdpi.com/1660-4601/19/1/193">study</a> of 1,800 Dutch cat owners, half said their cat was family. One in three viewed their cat as a child or best friend and found them loyal, supportive and empathetic.</p> <p>Another US study developed a “<a href="https://www.frontiersin.org/journals/veterinary-science/articles/10.3389/fvets.2021.812922/full">family bondedness</a>” scale and found cats were just as important a part of families as dogs.</p> <p>Many cats would choose <a href="https://www.sciencedirect.com/science/article/abs/pii/S0376635716303424">human interaction</a> over food or toys. And <a href="https://link.springer.com/article/10.1007/s10071-022-01674-w">they can distinguish</a> when we are talking to them (rather than another human).</p> <p>In fact we’ve adapted to each other. Cats are <a href="https://www.nature.com/articles/s41598-020-73426-0">more likely</a> to approach human strangers who first give a “kitty kiss” – narrowing your eyes and blinking slowly. And research suggests cats have developed <a href="https://theconversation.com/why-cats-meow-at-humans-more-than-each-other-232865">specific meows</a> that tune into our nurturing instincts.</p> <p>What does this close relationship mean for health outcomes?</p> <h2>A sense of purpose</h2> <p>Owning a pet is associated with <a href="https://link.springer.com/article/10.1007/s00127-022-02332-9">less social isolation</a>. And <a href="https://www.cabidigitallibrary.org/doi/full/10.1079/hai.2021.0006">some cat owners</a> say “providing for the cat” increases their feelings of enjoyment and sense of purpose.</p> <p>But the benefits of the relationship may depend on how you relate to your cat.</p> <p><a href="https://www.mdpi.com/2076-2615/11/6/1601">One study</a> looked at different relationship styles between humans and cats, including “remote”, “casual” and “co-dependent”. It found people whose relationship with their cat was co-dependent or like a friend had a higher emotional connection to their pet.</p> <h2>Links to heart health</h2> <p>People who own – or have owned – a cat have a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3317329/">lower risk</a> of dying from cardiovascular diseases such as stroke or heart disease. This result has been repeated in several <a href="https://journals.lww.com/jcardiovascularmedicine/fulltext/2020/05000/association_between_pet_ownership_and.3.aspx?casa_token=JmAlt8nNRAUAAAAA:NdUb0DK3DF6Fej0Vrx9t55JK-HZPmE7F1teQeDCCt3vy0Ha3aSNwZeA4KMcTVm-4ZWz1n-rEVUhIE62CUcfXhAn0sA5RQg">studies</a>.</p> <p>However a problem interpreting population studies is they only tell us about an association. This means while people with cats have lower risk of dying from cardiovascular diseases, we can’t say for sure cats are the cause.</p> <p>Cat ownership has also been associated with some positive changes in the <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0253133">gut microbiota</a>, especially in women, such as improved blood glucose control and reduced inflammation.</p> <h2>Helping mental health</h2> <p>Having cat or dog is also associated with <a href="https://www.tandfonline.com/doi/full/10.1080/08927936.2023.2182029">higher psychological well-being</a>. For people with depression, patting or playing with their cat <a href="https://www.tandfonline.com/doi/abs/10.2752/089279399787000066">has been shown</a> to reduce symptoms (although this was over a short, two-hour period and can’t be extrapolated longer-term).</p> <p>Another way to find out about the health impact of cats is qualitative research: asking people what their cats mean to them, beyond the numbers.</p> <p>When colleagues and I <a href="https://www.cabidigitallibrary.org/doi/full/10.1079/hai.2023.0013">surveyed veterans</a>, we found people more attached to their pets actually had poorer mental health scores. But their survey responses told a different story. One respondent said, “my cats are the reason I get up in the morning”.</p> <p>Another wrote:</p> <blockquote> <p>I consider my pet to be a service animal. My cat helps me to relax when I’m dealing with my anxiety, depression or when I wake during the night from the frequent nightmares I have. My cat isn’t just a pet to me, my cat is a part of me, my cat is part of my family.</p> </blockquote> <p>It may be that veterans were more attached to their cats because they had worse mental health – and relied on their cats more for comfort – rather than the other way around.</p> <h2>Mental health downsides</h2> <p>It is possible being attached to your cat has downsides. If your cat becomes sick, the burden of caring for them may have a negative impact on your mental health.</p> <p><a href="https://bvajournals.onlinelibrary.wiley.com/doi/abs/10.1002/vetr.836?casa_token=g2tT-K2uFUcAAAAA%3AkxrkxlT5voEB8-GpKtiY2pX8qCDgFMjqDZPNS5L2AavYLAlfs6CG_wtsICp7bv-a3TtPMclLHl8edNE">In our study</a> of owners whose cats had epilepsy, around one third experienced a clinical level of burden as caregivers that was likely to interfere with their day-to-day functioning.</p> <h2>Toxoplasmosis</h2> <p>Cats can also carry <a href="https://www.who.int/news-room/fact-sheets/detail/zoonoses">zoonotic</a> diseases, which are infections which spread from animals to humans.</p> <p>They are the main host for <a href="https://www.vet.cornell.edu/departments-centers-and-institutes/cornell-feline-health-center/health-information/feline-health-topics/toxoplasmosis-cats">toxoplasmosis</a>, a parasite excreted in cat faeces which can affect other mammals, including humans.

Eight simple changes to our neighbourhoods can help us age well

<p><em><a href="https://theconversation.com/profiles/jerome-n-rachele-251972">Jerome N Rachele</a>, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a>; <a href="https://theconversation.com/profiles/james-f-sallis-407885">James F Sallis</a>, <a href="https://theconversation.com/institutions/university-of-california-san-diego-1314">University of California, San Diego</a>, and <a href="https://theconversation.com/profiles/venurs-loh-118864">Venurs Loh</a>, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a></em></p> <p>Where we live can play a big part in ageing well, largely because of the links between physical activity and wellbeing. <a href="https://www.ahuri.edu.au/__data/assets/pdf_file/0012/2181/AHURI_Final_Report_No214_Downsizing-amongst-older-Australians.pdf">Research shows</a> that two-thirds of Australians prefer to age in place. That is, we want to live independently in our homes for as long as we can. Our neighbourhoods and their design can then improve or hinder our ability to get out of the house and be physically active.</p> <p>The rapid ageing of Australia’s population only adds to the importance of neighbourhood design. In 2016, 15% of Australians were aged 65 or older. That proportion is <a href="https://www.aihw.gov.au/reports-statistics/population-groups/older-people/overview">projected to double</a> by 2056.</p> <p>These trends present several <a href="https://www.aihw.gov.au/reports-statistics/population-groups/older-people/reports">social and economic challenges</a>, particularly for the health sector. Designing neighbourhoods in ways that promote physical activity can help overcome these challenges.</p> <h2>Eight simple steps</h2> <p>The following is a short list of <a href="https://ijbnpa.biomedcentral.com/articles/10.1186/s12966-017-0471-5">evidence-based steps</a> local and state governments can take to assist older people to be physically active. These involve minor but effective changes to neighbourhood design.</p> <p><strong>Improve footpaths:</strong> Research indicates that older people have a <a href="https://theconversation.com/why-older-people-get-osteoporosis-and-have-falls-68145">higher risk of falls</a>. Ensuring footpaths are level and crack-free, and free from obstructions, will encourage walking among older people – especially those with a disability.</p> <p><strong>Connected pedestrian networks:</strong> Introducing footpaths at the end of no-through-roads and across long street blocks reduces walking distances to destinations. This makes walking a more viable option.</p> <p><strong>Slowing traffic in high-pedestrian areas:</strong> Slowing traffic <a href="https://www.heartfoundation.org.au/images/uploads/publications/Safe-Speed-Evidence-Report.pdf">improves safety</a> by reducing the risk of a collision. It also reduces the risk of <a href="https://www.ncbi.nlm.nih.gov/pubmed/28557669">death and serious injury</a> in the event of a collision.</p> <p><strong>Age-friendly street crossings:</strong> Installing longer pedestrian crossing light sequences gives older pedestrians <a href="https://academic.oup.com/ageing/article/41/5/690/47318/Most-older-pedestrians-are-unable-to-cross-the">more time to cross</a>, and installing refuge islands means those who walk more slowly can cross the street in two stages.</p> <p><strong>Disabled access at public transport:</strong> Although a form of motorised transport, public transport users undertake more incidental physical activity compared with car users. This is because they walk between transit stops and their origins and destinations. Improving disabled access helps make public transport a viable option for more older people.</p> <p><strong>Places to rest:</strong> <a href="https://bmcpublichealth.biomedcentral.com/articles/10.1186/1471-2458-13-1054">Providing rest spots</a> such as benches enables older people to break up their walk and rest when needed.</p> <p><strong>Planting trees:</strong> Planting trees <a href="http://www.sciencedirect.com/science/article/pii/S0277953614004109?via%3Dihub">creates more pleasant scenery</a> to enjoy on a walk. It also provides shade on hot days.</p> <p><strong>Improving safety:</strong> Ensuring that streets are well-lit and reducing graffiti and signs of decay are likely to <a href="https://www.ncbi.nlm.nih.gov/pubmed/24552845">improve perceptions of safety</a> among older people.</p> <h2>Why physical activity matters</h2> <p>Physical function – the ability to undertake everyday activities such as walking, bathing and climbing stairs – often declines as people age. The reason for this is that ageing is often accompanied by a reduction in muscle strength, flexibility and cardiorespiratory reserves.</p> <p>Regular physical activity can <a href="https://www.ncbi.nlm.nih.gov/pubmed/14552936">prevent or slow the decline</a> in physical function, even among those with existing health conditions.</p> <p>Middle-to-older aged adults can reduce their risk of physical function decline <a href="https://ijbnpa.biomedcentral.com/articles/10.1186/1479-5868-7-38">by 30%</a> with regular physical activity (at least 150 minutes per week). This includes recreational physical activity, like walking the dog, or incidental physical activity, such as walking to the shops or to visit friends.</p> <p>By making minor changes as outlined above, the health and longevity of our elderly population can be extended. Such changes will help our elderly age well in place.</p> <p><em><a href="https://theconversation.com/profiles/jerome-n-rachele-251972">Jerome N Rachele</a>, Research Fellow in Social Epidemiology, Institute for Health and Ageing, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a>; <a href="https://theconversation.com/profiles/james-f-sallis-407885">James F Sallis</a>, Professorial Fellow, Institute for Health and Ageing, Australian Catholic University, and Emeritus Professor, Department of Family Medicine and Public Health, <a href="https://theconversation.com/institutions/university-of-california-san-diego-1314">University of California, San Diego</a>, and <a href="https://theconversation.com/profiles/venurs-loh-118864">Venurs Loh</a>, PhD Candidate, Institute for Health and Ageing, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

An unbroken night’s sleep is a myth. Here’s what good sleep looks like

<p><em><a href="https://theconversation.com/profiles/amy-reynolds-424346">Amy Reynolds</a>, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a>; <a href="https://theconversation.com/profiles/claire-dunbar-1651340">Claire Dunbar</a>, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a>; <a href="https://theconversation.com/profiles/gorica-micic-187159">Gorica Micic</a>, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a>; <a href="https://theconversation.com/profiles/hannah-scott-424633">Hannah Scott</a>, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a>, and <a href="https://theconversation.com/profiles/nicole-lovato-60684">Nicole Lovato</a>, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a></em></p> <p>What do you imagine a good night’s sleep to be?</p> <p>Often when people come into our sleep clinic seeking treatment, they share ideas about healthy sleep.</p> <p>Many think when their head hits the pillow, they should fall into a deep and restorative sleep, and emerge after about eight hours feeling refreshed. They’re in good company – many Australians hold <a href="https://doi.org/10.1016/j.jpsychores.2014.09.011">the same belief</a>.</p> <p>In reality, healthy sleep is cyclic across the night, as you move in and out of the different stages of sleep, often waking up several times. Some people remember one or more of these awakenings, others do not. Let’s consider what a healthy night’s sleep looks like.</p> <h2>Sleep cycles are a roller-coaster</h2> <p>As an adult, our sleep moves through <a href="https://www.sleepfoundation.org/stages-of-sleep">different cycles</a> and brief awakenings during the night. Sleep cycles last roughly 90 minutes each.</p> <p>We typically start the night with lighter sleep, before moving into deeper sleep stages, and rising again into rapid eye movement (REM) sleep – the stage of sleep often linked to vivid dreaming.</p> <p>If sleeping well, we get most of our deep sleep in the first half of the night, with <a href="https://www.nhlbi.nih.gov/health/sleep/stages-of-sleep#:%7E:text=During%20REM%20sleep%2C%20your%20eyes,from%20acting%20out%20your%20dreams">REM sleep</a> more common in the second half of the night.</p> <p>Adults usually move through five or six sleep cycles in a night, and it is entirely <a href="https://doi.org/10.1016/j.jpsychores.2014.09.011">normal</a> to wake up briefly at the end of each one. That means we might be waking up five times during the night. This can increase with older age and still be healthy. If you’re not remembering these awakenings that’s OK – they can be quite brief.</p> <h2>What does getting a ‘good’ sleep actually mean?</h2> <p>You’ll often hear that adults <a href="https://www.sleephealthfoundation.org.au/sleep-topics/how-much-sleep-do-you-really-need#:%7E:text=Sleep%20requirements%20stabilise%20in%20early,their%20best%20the%20next%20day">need between seven and nine hours</a> of sleep per night. But good sleep is about more than the number of hours – it’s also about the quality.</p> <p>For most people, sleeping well means being able to fall asleep soon after getting into bed (within around 30 minutes), sleeping without waking up for long periods, and waking feeling rested and ready for the day.</p> <p>You shouldn’t be feeling excessively sleepy during the day, especially if you’re regularly getting at least seven hours of refreshing sleep a night (this is a rough rule of thumb).</p> <p>But are you noticing you’re feeling physically tired, needing to nap regularly and still not feeling refreshed? It may be worthwhile touching base with your general practitioner, as there a range of possible reasons.</p> <h2>Common issues</h2> <p>Sleep disorders are common. Up to <a href="https://pubmed.ncbi.nlm.nih.gov/35478719/">25% of adults</a> have insomnia, a sleep disorder where it may be hard to fall or stay asleep, or you may wake earlier in the morning than you’d like.</p> <p>Rates of common sleep disorders such as insomnia and <a href="https://www.mayoclinic.org/diseases-conditions/sleep-apnea/symptoms-causes/syc-20377631">sleep apnoea</a> – where your breathing can partially or completely stop many times during the night – also increase with age, affecting <a href="https://pubmed.ncbi.nlm.nih.gov/32280974/">20% of early adults</a> and 40% of people in <a href="https://pubmed.ncbi.nlm.nih.gov/35082023/">middle age</a>. There are effective treatments, so asking for help is important.</p> <p>Beyond sleep disorders, our sleep can also be disrupted by chronic health conditions – such as <a href="https://www.sciencedirect.com/science/article/abs/pii/S0012369218311139">pain</a> – and by <a href="https://onlinelibrary.wiley.com/doi/10.1111/jsr.13075">certain medications</a>.</p> <p>There can also be other reasons we’re not sleeping well. Some of us are woken by children, pets or traffic noise during the night. These “<a href="https://www.tandfonline.com/doi/full/10.1080/07420528.2021.2003375">forced awakenings</a>” mean we may find it harder to get up in the morning, take longer to leave bed and feel less satisfied with our sleep. For some people, night awakenings may have no clear cause.</p> <p>A good way to tell if these awakenings are a problem for you is by thinking about how they affect you. When they cause feelings of frustration or worry, or are impacting how we feel and function during the day, it might be a sign to seek some help.</p> <p>We also may struggle to get up in the morning. This could be for a range of reasons, including not sleeping long enough, going to bed or waking up at irregular times – or even your own <a href="https://www.sleephealthfoundation.org.au/sleep-categories/circadian-rhythm-disorders#:%7E:text=The%20circadian%20rhythms%20throughout%20the,regulation%20of%20our%20sleeping%20patterns">internal clock</a>, which can influence the time your body prefers to sleep.</p> <p>If you’re regularly struggling to get up for work or family needs, it can be an indication you may need to seek help. Some of these factors can be explored with a sleep psychologist if they are causing concern.</p> <h2>Can my smart watch help?</h2> <p>It is important to remember sleep-tracking devices can <a href="https://www.nature.com/articles/s41746-024-01016-9">vary in accuracy</a> for looking at the different sleep stages. While they can give a rough estimate, they are not a perfect measure.</p> <p>In-laboratory <a href="https://pubmed.ncbi.nlm.nih.gov/31277862/">polysomnography</a>, or PSG, is the best standard measure to examine your sleep stages. A PSG examines breathing, oxygen saturation, brain waves and heart rate during sleep.</p> <p>Rather than closely examining nightly data (including sleep stages) from a sleep tracker, it may be more helpful to look at the patterns of your sleep (bed and wake times) over time.</p> <p><a href="https://jcsm.aasm.org/doi/10.5664/jcsm.8356">Understanding your sleep patterns</a> may help identify and adjust behaviours that negatively impact your sleep, such as your bedtime routine and sleeping environment.</p> <p>And if you find viewing your sleep data is making you feel worried about your sleep, this may not be useful for you. Most importantly, if you are concerned it is important to discuss it with your GP who can refer you to the appropriate specialist sleep health provider.<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/238069/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/amy-reynolds-424346">Amy Reynolds</a>, Associate Professor in Clinical Sleep Health, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a>; <a href="https://theconversation.com/profiles/claire-dunbar-1651340">Claire Dunbar</a>, Research Associate, Sleep Health, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a>; <a href="https://theconversation.com/profiles/gorica-micic-187159">Gorica Micic</a>, Postdoctoral Research Fellow, Clinical Psychologist, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a>; <a href="https://theconversation.com/profiles/hannah-scott-424633">Hannah Scott</a>, Research Fellow in Sleep Health, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a>, and <a href="https://theconversation.com/profiles/nicole-lovato-60684">Nicole Lovato</a>, Associate Professor, Adelaide Institute for Sleep Health, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

We tend to underestimate our future expenses – here’s one way to prevent that

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/ray-charles-chuck-howard-1361224">Ray Charles "Chuck" Howard</a>, <a href="https://theconversation.com/institutions/texas-aandm-university-1672">Texas A&amp;M University</a>; <a href="https://theconversation.com/profiles/abigail-sussman-227057">Abigail Sussman</a>, <a href="https://theconversation.com/institutions/university-of-chicago-952">University of Chicago</a>; <a href="https://theconversation.com/profiles/david-j-hardisty-753777">David J.

However, when prompted to think about unexpected spending in addition to typical expenses, people made much more accurate predictions.</p> <p>These are the main findings of a series of <a href="https://doi.org/10.1177%2F00222437211068025">studies and experiments that we conducted</a> and which have just been published in the <a href="https://journals.sagepub.com/home/mrj">Journal of Marketing Research</a>.</p> <p>In our first study, we began by asking 187 members of a Canadian credit union to predict their weekly spending for the next five weeks. Then, at the end of each week, we asked them how much they actually spent.</p> <p>For the first four weeks, people underpredicted their weekly spending by about $100 per week or $400 for the month.</p> <p>In the study’s fifth and final week, we ran an experiment to see if we could improve people’s prediction accuracy.</p> <p>Specifically, we randomly assigned participants to one of two groups. In group one, participants estimated their spending for the next week just as they had done in previous weeks. These folks once again significantly underpredicted their spending.</p> <p>In group two, participants were asked to think of three reasons why their spending for the next week might be different than usual before making their estimate. This led them to make higher and much more accurate predictions – coming within just $7 of what they actually spent.</p> <p>Importantly, participants in each group spent roughly the same amount of money that week, on average. The only difference between the two groups was whether they accurately predicted that amount.</p> <p><iframe id="WlDv3" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/WlDv3/3/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe></p> <p>Next, we conducted nine experiments to better understand why people underpredict their spending and whether being prompted to think of unusual expenses helps improve accuracy. In all, over 5,800 people participated in these experiments, including a representative sample of U.S. residents.</p> <p>These experiments revealed two important insights.</p> <p>First, people primarily base their spending predictions on typical expenses like groceries, gasoline and rent. They usually fail to account for irregular – though still common – expenses like car repairs, last-minute concert tickets or one-off health care bills. This is what leads to underprediction.</p> <p>Second, prompting people to think of irregular expenses in addition to typical expenses helps them to make more accurate spending predictions. In our studies, people did not factor in atypical expenses unless we asked them to do so.</p> <h2>Why it matters</h2> <p>Helping people improve the accuracy of their spending predictions could help them improve their financial well-being.</p> <p>Underpredicting expenses can be costly. For example, 12 million Americans <a href="https://www.pewtrusts.org/en/research-and-analysis/reports/2012/07/19/who-borrows-where-they-borrow-and-why">borrow a total of more than $7 billion</a> in payday loans each year because they can’t meet their monthly expenses. These loans typically have extremely high interest rates – <a href="https://www.pewtrusts.org/en/research-and-analysis/data-visualizations/2022/how-well-does-your-state-protect-payday-loan-borrowers">more than 250% in some states</a>.</p> <p>Payday loans also come due in full so quickly that around three in four borrowers <a href="https://www.pewtrusts.org/en/research-and-analysis/reports/2012/07/19/who-borrows-where-they-borrow-and-why">end up borrowing again</a> to pay off the original loan.</p> <p>If consumers could better anticipate how much money they will spend in the future, it might help motivate them to spend less and save more in the present.</p> <p>In fact, one of our studies shows that our suggested prediction strategy <a href="https://doi.org/10.1177/0022243721106802">not only boosted spending estimates</a>, it also increased intentions to save.</p> <h2>What’s next</h2> <p>Members of our research team are currently investigating if, when and why underpredicting one’s expenses may be beneficial. For example, if a person sets an optimistically low budget and actively tracks their spending against it, does that help them reduce their spending?</p> <p>We are also investigating whether people who work in the gig economy show a corresponding tendency to mispredict their future income.<!-- Below is The Conversation's page counter tag.

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

In the Middle Ages we had the Black Death (plague), and after the first world war we had the Spanish flu. Tens of millions of people <a href="https://assets.cureus.com/uploads/review_article/pdf/69273/20211019-25919-an4y6h.pdf">died from these diseases</a>.</p> <p>Then science began to <a href="https://www.frontiersin.org/journals/immunology/articles/10.3389/fimmu.2011.00053/full">get the upper hand</a>, with vaccination eradicating smallpox, and polio nearly so. Antibiotics became available to treat bacterial infections, and more recently antivirals as well.</p> <p>But in recent years and decades pandemics <a href="https://assets.cureus.com/uploads/review_article/pdf/69273/20211019-25919-an4y6h.pdf">seem to be returning</a>. In the 1980s we had HIV/AIDS, then several flu pandemics, SARS, and now COVID (no, COVID isn’t over).</p> <p>So why is this happening, and is there anything we can do to avert future pandemics?</p> <h2>Unbalanced ecosystems</h2> <p>Healthy, stable ecosystems provide services that keep us healthy, such as supplying food and clean water, producing oxygen, and making green spaces available for our <a href="https://www.millenniumassessment.org/documents/document.356.aspx.pdf">recreation and wellbeing</a>.</p> <p>Another key service ecosystems provide is disease regulation. When nature is in balance – with predators controlling herbivore populations, and herbivores controlling plant growth – it’s more difficult for pathogens to emerge in a way that causes pandemics.</p> <p>But when human activities <a href="https://books.google.com.au/books?hl=en&amp;lr=&amp;id=rWozz12K1aUC&amp;oi=fnd&amp;pg=PP15&amp;dq=planetary+overload&amp;ots=c9mWuESUXN&amp;sig=-1iP3uSOWazvC2OFLk4vginWbQQ&amp;redir_esc=y#v=onepage&amp;q=planetary%20overload&amp;f=false">disrupt and unbalance ecosystems</a> – such as by way of climate change and biodiversity loss – <a href="https://academic.oup.com/bioscience/article/58/8/756/381265">things go wrong</a>.</p> <p>For example, climate change affects the number and distribution of plants and animals. Mosquitoes that carry diseases can move from the tropics into what used to be temperate climates as the planet warms, and may infect more people in the months that are normally disease free.</p> <p>We’ve studied the relationship between weather and dengue fever transmission in China, and <a href="https://pubmed.ncbi.nlm.nih.gov/27883970/">our findings</a> support the same conclusion reached by <a href="https://journals.plos.org/plosntds/article?id=10.1371/journal.pntd.0008118">many other studies</a>: climate change is likely to put more people at risk of dengue.</p> <p>Biodiversity loss can have similar effects by disrupting food chains. When ranchers cleared forests in <a href="https://www.mdpi.com/1999-4915/6/5/1911">South America</a> for their cattle to graze in the first half of the 20th century, tiny forest-dwelling, blood-feeding vampire bats suddenly had a smörgåsbord of large sedentary animals to feed on.</p> <p>While vampire bats had previously been kept in check by the limited availability of food and the presence of predators in the balanced <a href="https://cir.nii.ac.jp/crid/1130000797648461952">forest ecosystem</a>, numbers of this species exploded in South America.</p> <p>These bats carry the rabies virus, which causes <a href="https://www.who.int/news-room/fact-sheets/detail/rabies">lethal brain infections</a> in people who are bitten. Although the number of deaths from bat-borne rabies has now fallen dramatically due to vaccination programs in South America, rabies caused by bites from other animals still <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3168224/">poses a global threat</a>.</p> <p>As urban and agricultural development impinges on natural ecosystems, there are increasing opportunities for humans and domestic animals to become infected with pathogens that would normally only be seen in wildlife – particularly when people hunt and eat animals from the wild.</p> <p>The HIV virus, for example, <a href="https://www.tandfonline.com/doi/abs/10.1076/jmep.27.2.163.2992">first entered human populations</a> from apes that were slaughtered for food in Africa, and then spread globally through travel and trade.</p> <p>Meanwhile, bats are thought to be <a href="https://www.sciencedirect.com/science/article/pii/S0006291X20319434">the original reservoir</a> for the virus that caused the COVID pandemic, which has killed more than <a href="https://www.worldometers.info/coronavirus/">7 million people</a> to date.</p> <p>Ultimately, until we effectively address the unsustainable impact we are having on our planet, pandemics will continue to occur.</p> <h2>Targeting the ultimate causes</h2> <p>Factors such as climate change, biodiversity loss and other global challenges are the ultimate (high level) cause of pandemics. Meanwhile, increased contact between humans, domestic animals and wildlife is the proximate (immediate) cause.</p> <p>In the case of HIV, while direct contact with the infected blood of apes was the proximate cause, the apes were only being slaughtered because large numbers of very poor people were hungry – an ultimate cause.</p> <p>The distinction between <a href="https://link.springer.com/article/10.1007/BF02207379">ultimate causes and proximate causes</a> is important, because we often deal only with proximate causes. For example, people may smoke because of stress or social pressure (ultimate causes of getting lung cancer), but it’s the toxins in the smoke that cause cancer (proximate cause).</p> <p>Generally, health services are only concerned with stopping people from smoking – and with treating the illness that results – not with removing the drivers that lead them to smoke in the first place.</p> <p>Similarly, we address pandemics with lockdowns, mask wearing, social distancing and vaccinations – all measures which seek to stop the spread of the virus. But we pay less attention to addressing the ultimate causes of pandemics – until perhaps very recently.</p> <h2>A planetary health approach</h2> <p>There’s a growing awareness of the importance of adopting a “planetary health” approach to improve human health. This <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(15)60901-1/fulltext?nr_email_referer=1">concept</a> is based on the understanding that human health and human civilisation depend on flourishing natural systems, and the wise stewardship of those natural systems.</p> <p>With this approach, ultimate drivers like climate change and biodiversity loss would be prioritised in preventing future pandemics, at the same time as working with experts from many different disciplines to deal with the proximate causes, thereby reducing the risk overall.</p> <p>The planetary health approach has the benefit of improving both the health of the environment and human health concurrently. We are heartened by the increased uptake of teaching planetary health concepts across the environmental sciences, humanities and health sciences in many universities.</p> <p>As climate change, biodiversity loss, population displacements, travel and trade continue to increase the risk of disease outbreaks, it’s vital that the planetary stewards of the future have a better understanding of how to tackle the ultimate causes that drive pandemics.</p> <p><em>This article is the first in a series on the next pandemic.</em><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/226827/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/olga-anikeeva-1522907"><em>Olga Anikeeva</em></a><em>, Research Fellow, School of Public Health, <a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a>; <a href="https://theconversation.com/profiles/jessica-stanhope-1129888">Jessica Stanhope</a>, Lecturer, School of Allied Health Science and Practice, <a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a>; <a href="https://theconversation.com/profiles/peng-bi-1522908">Peng Bi</a>, Professor, School of Public Health, <a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a>, and <a href="https://theconversation.com/profiles/philip-weinstein-882901">Philip Weinstein</a>, Professorial Research Fellow, School of Public Health, <a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Does intermittent fasting increase or decrease our risk of cancer?

<p><em><a href="https://theconversation.com/profiles/amali-cooray-1482458">Amali Cooray</a>, <a href="https://theconversation.com/institutions/wehi-walter-and-eliza-hall-institute-of-medical-research-822"><em>WEHI (Walter and Eliza Hall Institute of Medical Research)</em></a></em></p> <p>Research over the years has suggested intermittent fasting has the potential to improve our health and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3946160/">reduce the likelihood</a> of developing cancer.</p> <p>So what should we make of a <a href="https://www.nature.com/articles/s41586-024-07840-z">new study</a> in mice suggesting fasting increases the risk of cancer?</p> <h2>What is intermittent fasting?</h2> <p>Intermittent fasting means switching between times of eating and not eating. Unlike traditional diets that focus on <em>what</em> to eat, this approach focuses on <em>when</em> to eat.</p> <p>There are lots of commonly used <a href="https://dietitiansaustralia.org.au/health-advice/intermittent-fasting">intermittent fasting schedules</a>. The 16/8 plan means you only eat within an eight-hour window, then fast for the remaining 16 hours. Another popular option is the 5:2 diet, where you eat normally for five days then restrict calories for two days.</p> <p>In Australia, poor diet contributes to <a href="https://www.health.gov.au/topics/food-and-nutrition/what-were-doing">7% of all cases of disease</a>, including coronary heart disease, stroke, type 2 diabetes, and cancers of the bowel and lung. Globally, poor diet is linked to <a href="https://www.thelancet.com/article/S0140-6736(19)30041-8/fulltext">22% of deaths</a> in adults over the age of 25.</p> <p>Intermittent fasting has gained a lot of attention in recent years for its potential health benefits. Fasting <a href="https://www.betterhealth.vic.gov.au/health/conditionsandtreatments/metabolism">influences metabolism</a>, which is how your body processes food and energy. It can affect how the body absorbs nutrients from food and burns energy from sugar and fat.</p> <h2>What did the new study find?</h2> <p>The <a href="https://www.nature.com/articles/s41586-024-07840-z">new study</a>, published in Nature, found when mice ate again after fasting, their <a href="https://www.nature.com/articles/s12276-024-01179-1">gut stem cells</a>, which help repair the intestine, became more active. The stem cells were better at regenerating compared with those of mice who were either totally fasting or eating normally.</p> <p>This suggests the body might be better at healing itself when eating after fasting.</p> <p>However, this could also have a downside. If there are <a href="https://www.cancer.gov/about-cancer/causes-prevention/genetics/genetic-changes-infographic">genetic mutations</a> present, the burst of stem cell-driven regeneration after eating again might make it easier for cancer to develop.</p> <p><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4027058/">Polyamines</a> – small molecules important for cell growth – drive this regeneration after refeeding. These polyamines can be produced by the body, influenced by diet, or come from gut bacteria.</p> <p>The findings suggest that while fasting and refeeding can improve stem cell function and regeneration, there might be a tradeoff with an increased risk of cancer, especially if fasting and refeeding cycles are repeated over time.</p> <p>While this has been shown in mice, the link between intermittent fasting and cancer risk in humans is more complicated and not yet fully understood.</p> <h2>What has other research found?</h2> <p><a href="https://www.annualreviews.org/content/journals/10.1146/annurev-nutr-071816-064634">Studies in animals</a> have found intermittent fasting can help with weight loss, improve blood pressure and blood sugar levels, and subsequently <a href="https://pubmed.ncbi.nlm.nih.gov/27810402/">reduce the risks</a> of diabetes and heart disease.</p> <p>Research in humans <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2811116">suggests</a> intermittent fasting can reduce body weight, improve <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9361187/">metabolic health</a>, reduce inflammation, and enhance <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3946160/">cellular repair processes</a>, which remove damaged cells that could potentially turn cancerous.</p> <p>However, other studies warn that the benefits of intermittent fasting are the same as what can be achieved through <a href="https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/2623528">calorie restriction</a>, and that there <a href="https://www.sciencedirect.com/science/article/pii/S2161831322007542">isn’t enough evidence</a> to confirm it reduces cancer risk in humans.</p> <h2>What about in people with cancer?</h2> <p>In studies of people who have cancer, fasting has been <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2815756/">reported to</a> protect against the side effects of chemotherapy and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7311547/">improve the effectiveness</a> of cancer treatments, while decreasing damage to healthy cells.</p> <p>Prolonged fasting in some patients who have cancer has been shown to be safe and <a href="https://pubmed.ncbi.nlm.nih.gov/34383300/">may potentially</a> be able to decrease tumour growth.</p> <p>On the other hand, some experts advise caution. Studies in mice show intermittent fasting could <a href="https://www.nature.com/articles/s41423-023-01033-w">weaken the immune system</a> and make the body less able to fight infection, potentially leading to worse health outcomes in people who are unwell. However, there is <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8757987/">currently no evidence</a> that fasting increases the risk of bacterial infections in humans.</p> <h2>So is it OK to try intermittent fasting?</h2> <p>The current view on intermittent fasting is that it can be beneficial, but experts agree more research is needed. Short-term benefits such as weight loss and better overall health are well supported. But we don’t fully understand the long-term effects, especially when it comes to cancer risk and other immune-related issues.</p> <p>Since there are many different methods of intermittent fasting and people react to them differently, it’s hard to <a href="https://www.nature.com/articles/s41423-023-01033-w">give advice that works for everyone</a>. And because most people who participated in the studies were overweight, or had diabetes or other health problems, we don’t know how the results apply to the broader population.</p> <p>For healthy people, intermittent fasting is generally considered safe. But it’s <a href="https://dietitiansaustralia.org.au/health-advice/intermittent-fasting">not suitable for everyone</a>, particularly those with certain medical conditions, pregnant or breastfeeding women, and people with a history of eating disorders. So consult your health-care provider before starting any fasting program.<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/238071/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/amali-cooray-1482458">Amali Cooray</a>, PhD Candidate in Genetic Engineering and Cancer, <a href="https://theconversation.com/institutions/wehi-walter-and-eliza-hall-institute-of-medical-research-822">WEHI (Walter and Eliza Hall Institute of Medical Research)</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Woman “bullied” on plane over budget seating trick

<p dir="ltr">A young woman has recalled a flight from hell when she was “bullied” by a couple who were trying to utilise a seating hack that went viral on TikTok. </p> <p dir="ltr">The solo traveller took to Reddit to recount the story and ask social media users if she was in the wrong for her action. </p> <p dir="ltr">The woman began by saying she usually pays more to select her plane seat ahead of time, but a medical emergency on another plane had her waiting on standby and left with no option other than to sit in a middle seat.</p> <p dir="ltr">When she was finally able to board, she was greeted by a couple who had purchased both the window and aisle seats in a bid to have more space, utilising a travel “trick” that has been popular on TikTok.</p> <p dir="ltr">The method, which has been dubbed the 'poor man's business class', usually leaves travellers with an empty middle seat and more space, and few travellers opt to pick a middle seat. </p> <p dir="ltr">“When I got to my row the man and woman were chatting and sharing a snack... it was obvious they were together. I mentioned to the man that I'm in the middle, and he got up to let me in,” the unsuspecting traveller wrote on Reddit.  </p> <p dir="ltr">“I asked them if they would prefer to sit together, I said I was totally okay with that. The woman reacted rudely to this and said ‘you're not supposed to be sitting here anyway’.”</p> <p dir="ltr">After noticing how the plane was full, she offered to show the pair her new ticket with the correct seat number on it.</p> <p dir="ltr">“She flicked her hand at my ticket and made a disgusted sound. I offered again if they wanted to sit together to which she didn't reply, her partner said it's okay and... made some small talk,” she continued. </p> <p dir="ltr">The man’s girlfriend then interrupted their conversation to ask,”'Did you use one of those third party websites to book your flight? It's so frustrating when people cheap out to inconvenience others.”</p> <p dir="ltr">The American woman explained that she had booked her flight directly and she had been placed on standby like everyone else and didn't choose the middle seat - she was assigned it.</p> <p dir="ltr">She then tried to keep the peace by refusing to engage with the furious woman.  </p> <p dir="ltr">“I was so done with her attitude, I put my headphones on and attempted to do my own thing,” she explained.</p> <p dir="ltr">But the “entitled” girlfriend wasn't letting it go, as the woman explained, “This woman kept reaching over me and tapping her partner and trying to talk to him in a way that was super intrusive.”</p> <p dir="ltr">“I could tell even her partner was trying to engage her less so that she would hopefully stop, but she didn't.”</p> <p dir="ltr">“I think they tried to pull that tactic where they don't sit together on purpose...hoping no one will sit between them. But on full flights it doesn't work. And even so - it's not the other person's fault.”</p> <p dir="ltr">The traveller's post was met with hundreds of comments slamming the girlfriend’s behaviour, as one person wrote, “It's like a toddler having a tantrum.”</p> <p dir="ltr">“She was disappointed and a total a**hole. Gross entitled people,” another added. </p> <p dir="ltr">Another person applauded the traveller’s level-headed behaviour, writing, “Wow! You are my hero for keeping it classy - I’m afraid I would not have been as kind as you.”</p> <p dir="ltr"><em>Image credits: Shutterstock </em></p>

Food and exercise can treat depression as well as a psychologist, our study found. And it’s cheaper

What has one got to do with the other?</p> <p>Our world-first trial, <a href="https://www.thelancet.com/journals/lanwpc/article/PIIS2666-6065%2824%2900136-6/fulltext">published this week</a>, shows improving diet and doing more physical activity can be as effective as therapy with a psychologist for treating low-grade depression.</p> <p>Previous studies (including <a href="https://link.springer.com/article/10.1186/s12916-017-0791-y">our own</a>) have found “lifestyle” therapies are effective for depression. But they have never been directly compared with psychological therapies – until now.</p> <p>Amid a nation-wide <a href="https://www.health.gov.au/sites/default/files/2023-10/national-mental-health-workforce-strategy-2022-2032.pdf">shortage</a> of mental health professionals, our research points to a potential solution. As we found lifestyle counselling was as effective as psychological therapy, our findings suggest dietitians and exercise physiologists may one day play a role in managing depression.</p> <h2>What did our study measure?</h2> <p>During the prolonged COVID lockdowns, Victorians’ distress levels were <a href="https://onlinelibrary.wiley.com/doi/full/10.5694/mja2.50831">high and widespread</a>. Face-to-face mental health services were limited.</p> <p>Our trial targeted people living in Victoria with elevated distress, meaning at least mild depression but not necessarily a diagnosed mental disorder. Typical symptoms included feeling down, hopeless, irritable or tearful.</p> <p>We partnered with our <a href="https://www.barwonhealth.org.au/mhdas/">local mental health service</a> to recruit 182 adults and provided group-based sessions on Zoom. All participants took part in up to six sessions over eight weeks, facilitated by health professionals.</p> <p>Half were randomly assigned to participate in a program co-facilitated by an accredited practising dietitian and an exercise physiologist. That group – called the lifestyle program – developed nutrition and movement goals:</p> <ul> <li>eating a wide variety of foods</li> <li>choosing high-fibre plant foods</li> <li>including high quality fats</li> <li>limiting discretionary foods, such as those high in saturated fats and added sugars</li> <li>doing enjoyable physical activity.</li> </ul> <p>The second group took part in psychotherapy sessions convened by two psychologists. The psychotherapy program used cognitive behavioural therapy (CBT), the gold standard for treating depression in <a href="https://jamanetwork.com/journals/jamapsychiatry/article-abstract/2730724">groups and when delivered remotely</a>.</p> <p>In both groups, participants could continue existing treatments (such as taking antidepressant medication). We gave both groups <a href="https://link.springer.com/article/10.1186/s12888-022-03840-3">workbooks and hampers</a>. The lifestyle group received a food hamper, while the psychotherapy group received items such as a colouring book, stress ball and head massager.</p> <h2>Lifestyle therapies just as effective</h2> <p>We found similar results in each program.</p> <p>At the trial’s beginning we gave each participant a score based on their self-reported mental health. We measured them again at the end of the program.</p> <p>Over eight weeks, those scores showed symptoms of depression reduced for participants in the lifestyle program (42%) and the psychotherapy program (37%). That difference was not statistically or clinically meaningful so we could conclude both treatments were as good as each other.</p> <p>There were some differences between groups. People in the lifestyle program improved their diet, while those in the psychotherapy program felt they had increased their social support – meaning how connected they felt to other people – compared to at the start of the treatment.</p> <p>Participants in both programs increased their physical activity. While this was expected for those in the lifestyle program, it was less expected for those in the psychotherapy program. It may be because they knew they were enrolled in a research study about lifestyle and subconsciously changed their activity patterns, or it could be a positive by-product of doing psychotherapy.</p> <p>There was also not much difference in cost. The lifestyle program was slightly cheaper to deliver: A$482 per participant, versus $503 for psychotherapy. That’s because hourly rates differ between dietitians and exercise physiologists, and psychologists.</p> <h2>What does this mean for mental health workforce shortages?</h2> <p>Demand for mental health services is increasing in Australia, while at the same time the workforce <a href="https://www.health.gov.au/sites/default/files/2023-10/national-mental-health-workforce-strategy-2022-2032.pdf">faces worsening nation-wide shortages</a>.</p> <p>Psychologists, who provide <a href="https://www.aihw.gov.au/getmedia/6b19e493-0ebe-420f-a9a3-e48b26aace9f/aihw-aus-249-ib.pdf?v=20240628145747&amp;inline=true">about half</a> of all mental health services, can have long wait times. Our results suggest that, with the appropriate training and guidelines, allied health professionals who specialise in diet and exercise could help address this gap.</p> <p>Lifestyle therapies can be combined with psychology sessions for multi-disciplinary care. But diet and exercise therapies could prove particularly effective for those on waitlists to see a psychologists, who may be receiving no other professional support while they wait.</p> <p>Many dietitians and exercise physiologists already have advanced skills and expertise in motivating behaviour change.

But while they enrich our lives in countless ways, we often fail to consider the potential impact of screen time on our cognitive abilities.</p> <p>In a <a href="https://link.springer.com/article/10.1007/s11065-023-09612-4">new meta-analysis</a> of dozens of earlier studies, we’ve found a clear link between disordered screen use and lower cognitive functioning.</p> <p>The findings suggest we should exercise caution before advocating for more screen time, and before introducing screens into even more aspects of daily life.</p> <h2>Young people’s screen time is increasing</h2> <p>In 2020, a UNSW Gonski Institute for Education report <a href="https://www.gie.unsw.edu.au/sites/default/files/documents/UNSW%20GIE%20GUD%20Phase%201%20Technical%20Report%20MAR20%20v2.pdf">noted a concerning statistic</a>: about 84% of Australian educators believe digital technologies are distracting in a learning environment.</p> <p>And according to the ABC, a recent Beyond Blue <a href="https://www.abc.net.au/news/2023-09-18/mental-health-depression-anxiety-support-coming-for-schools/102831464">survey</a> of Australian teachers identified excessive screen time as the second-most significant challenge for young people, just behind mental health issues.</p> <p>Despite mounting concerns, more than half of Australian schools have embraced a “<a href="https://www.linewize.io/anz/blog/the-rise-of-byod-in-australian-schools">bring your own device</a>” policy. Students are spending more time online than <a href="https://read.oecd-ilibrary.org/education/students-computers-and-learning_9789264239555-en#page46">ever before</a> and starting at increasingly younger ages. A 2021 report by <a href="https://www.commonsensemedia.org/sites/default/files/research/report/8-18-census-integrated-report-final-web_0.pdf">Common Sense Media</a> estimated tweens spend an average of 5 hours and 33 minutes using screen-based entertainment each day, while teenagers devote a whopping 8 hours and 39 minutes.</p> <p>A surge in screen use has led to some individuals, including children, adolescents and adults, developing screen-related addictions. One example is gaming disorder, for which <a href="https://journals.sagepub.com/doi/full/10.1177/0004867420962851">2–3% of people</a> meet the criteria.</p> <h2>What is ‘disordered screen use’?</h2> <p>The impact of screens on our cognitive abilities – that is, our thinking skills such as attention, memory, language and problem-solving – has sparked much debate.</p> <p>On one hand, some researchers and reporters claim screen use can have negative effects, such as <a href="https://bmcpublichealth.biomedcentral.com/articles/10.1186/s12889-022-12701-3">health problems</a>, shortened attention <a href="https://time.com/3858309/attention-spans-goldfish/">spans</a> and hindered <a href="https://www.researchgate.net/publication/312489265_The_relationship_between_television_exposure_and_children's_cognition_and_behaviour_A_systematic_review">development</a>.</p> <p>On the other, schools are <a href="https://www.smh.com.au/education/tech-takeover-classrooms-crowded-with-digital-devices-20200125-p53ul1.html">increasingly adopting</a> technology to boost student engagement. Tech companies are also marketing their products as tools to help you enhance your problem-solving and memory skills.</p> <p>Our <a href="https://link.springer.com/article/10.1007/s11065-023-09612-4">recent study</a> sought to understand the potential cognitive consequences of “disordered screen-related behaviours”. This is a broad category of problematic behaviours that may include screen dependency, and persisting with screen use even when it’s harmful.</p> <p>We conducted a meta-analysis of 34 studies that explored various forms of screen use (including gaming, internet browsing, smartphone use and social media use) and compared the cognitive performance of individuals with disordered screen use to those without it.</p> <p>Our findings paint a concerning picture.</p> <h2>Differences in cognitive function</h2> <p>Across these rigorously peer-reviewed studies, individuals with disordered screen use consistently demonstrated significantly poorer cognitive performance compared to others.</p> <p>The most affected cognitive domain was attention, and specifically sustained attention, which is the ability to maintain focus on an unchanging stimulus for an extended period.</p> <p>The second-most notable difference was in their “executive functioning” – particularly in impulse control, which is the ability to control one’s automatic responses.</p> <p>Interestingly, the type of screen activity didn’t make a difference in the results. The trend also wasn’t confined to children, but was observed across all age groups.</p> <h2>Two ways to interpret the results</h2> <p>Why do people with disordered screen-related behaviours have poorer cognitive functioning?</p> <p>The first explanation is that disordered screen use actually leads to poorer cognitive function, including poorer attention skills (but we’ll need more experimental and longitudinal studies to establish causality).</p> <p>If this is the case, it may be the result of being constantly bombarded by algorithms and features designed to capture our attention. By diverting our focus outward, screen use may weaken one’s intrinsic ability to concentrate over time.</p> <p>Crucially, impaired attention also <a href="https://akjournals.com/view/journals/2006/10/1/article-p77.xml">makes it harder to disengage</a> from addictive behaviours, and would therefore make it harder to recognise when screen use has become a problem.</p> <p>The second explanation is that people who already have poorer cognitive functioning (such as less inhibitory control) are more likely to engage in disordered screen use.</p> <p>This could be a result of the plethora of addictive cues designed to keep us glued to our screens. Being bombarded by these could make it harder to <a href="https://akjournals.com/view/journals/2006/9/4/article-p990.xml">pull the brakes</a> on screen use.</p> <p>Although the literature doesn’t seem to favour this explanation – and does seem to suggest that cognitive functioning is impaired as a result of disordered screen use – it’s still a possibility we can’t rule out.</p> <p>Attention is the bedrock of everyday tasks. People with weakened attention may struggle to keep up in less stimulating environments, such as a static workplace or classroom. They may find themselves turning to a screen as a result.</p> <p>Similarly, people with less inhibitory control would also find it more challenging to moderate their screen use. This could be what drives them towards problematic screen-related behaviours in the first place.</p> <h2>Who should shoulder the responsibility?</h2> <p>Research indicates people with impaired cognitive functioning usually aren’t as well equipped to moderate their own screen time.</p> <p>Many users with disordered screen use are <a href="https://www.sciencedirect.com/science/article/pii/S0747563220302326?casa_token=BQv_N_MFffYAAAAA:AsGkAfdwXjCZHJB463G40Mx-ckS2Q1c8jSOn2SWR_9iW64eWaQsru1IJAZBDCgSPXwhZ3Qwl">young</a>, with mainly males engaging in internet gaming and mainly females engaging in social media use. Neurodiverse people are <a href="https://www.mdpi.com/1660-4601/19/9/5587">also at greater risk</a>.</p> <p>Tech companies are driven by the goal of <a href="https://www.theguardian.com/technology/2017/apr/18/netflix-competitor-sleep-uber-facebook">capturing our attention</a>. For instance, Netflix chief executive Reed Hastings acknowledged the company’s <a href="https://www.theguardian.com/technology/2017/apr/18/netflix-competitor-sleep-uber-facebook">most formidable competitor was sleep</a>.</p> <p>At the same time, researchers find themselves struggling to keep up with the pace of technological innovation. A potential path forward is to encourage open-access data policies from tech companies, so researchers can delve deeper into the study of screen use and its effect on individuals. <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/216828/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/michoel-moshel-1433565">Michoel Moshel</a>, PhD/Masters Clinical Neuropsychology Candidate, <a href="https://theconversation.com/institutions/macquarie-university-1174">Macquarie University</a>; <a href="https://theconversation.com/profiles/jennifer-batchelor-1485101">Jennifer Batchelor</a>, Associate Professor, School of Psychological Sciences, <a href="https://theconversation.com/institutions/macquarie-university-1174">Macquarie University</a>; <a href="https://theconversation.com/profiles/joanne-bennett-1485102">Joanne Bennett</a>, Lecturer, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a>, and <a href="https://theconversation.com/profiles/wayne-warburton-402810">Wayne Warburton</a>, Associate Professor, <a href="https://theconversation.com/institutions/macquarie-university-1174">Macquarie University</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Our obsession with taking photos is changing how we remember the past

<p><em><a href="https://theconversation.com/profiles/giuliana-mazzoni-175429">Giuliana Mazzoni</a>, <a href="https://theconversation.com/institutions/university-of-hull-1191">University of Hull</a></em></p> <p>I recently visited the <a href="http://hermitage--www.hermitagemuseum.org/wps/portal/hermitage/?lng=sv">Hermitage</a> in St Petersburg, Russia – one of the best art museums in the world. I was expecting to serenely experience its masterpieces, but my view was blocked by a wall of smart phones taking pictures of the paintings. And where I could find a bit of empty space, there were people taking selfies to create lasting memories of their visit.</p> <p>For many people, taking hundreds, if not thousands, of pictures is now a crucial part of going on holiday – documenting every last detail and posting it on social media. But how does that affect our actual memories of the past – and how we view ourselves? As an expert on memory, I was curious.</p> <p>Unfortunately, psychological research on the topic is so far scant. But we do know a few things. We use smart phones and new technologies <a href="http://studie-life.de/en/life-reports/smart-payments;%20https://www.researchgate.net/profile/Tim_Fawns/publication/275331048_Blended_Memory_the_Changing_Balance_of_Technologically-mediated_Semantic_and_Episodic_Memory/links/56962c6d08ae820ff07594ee.pdf">as memory repositories</a>. This is nothing new – humans have always used external devices as an aid when acquiring knowledge and remembering.</p> <p>Writing certainly serves this function. Historical records are collective external memories. Testimonies of migrations, settlement or battles help entire nations trace a lineage, a past and an identity. In the life of an individual, written diaries serve a similar function.</p> <h2>Memory effects</h2> <p>Nowadays we tend to commit very little to memory – we entrust a huge amount to the cloud. Not only is it almost unheard of to recite poems, even the most personal events are generally recorded on our cellphones. Rather than remembering what we ate at someone’s wedding, we scroll back to look at all the images we took of the food.</p> <p>This has serious consequences. Taking photos of an event rather than being immersed in it has been shown to lead to <a href="https://theconversation.com/memory-loss-isnt-just-an-old-persons-problem-heres-how-young-people-can-stay-mentally-fit-102352">poorer recall of the actual event</a> – we get distracted in the process.</p> <p>Relying on photos to remember has a similar effect. Memory needs to be exercised on a regular basis in order to function well. There are many studies documenting the importance of memory retrieval practice – <a href="http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.738.2035&amp;rep=rep1&amp;type=pdf">for example in university students</a>. Memory is and will remain essential for learning. There is indeed some evidence showing that committing almost all knowledge and memories to the cloud <a href="https://www.journals.uchicago.edu/doi/10.1086/691462">might hinder the ability to remember</a>.</p> <p>However, there is a silver lining. Even if some studies claim that all this makes us more stupid, what happens is actually shifting skills from purely being able to remember to being able to manage the way we remember more efficiently. This is called metacognition, and it is an overarching skill that is also essential for students – for example when planning what and how to study. There is also substantial and reliable evidence that external memories, selfies included, <a href="https://www.ncbi.nlm.nih.gov/pubmed/23957379">can help</a> individuals with memory impairments.</p> <p>But while photos can in some instances help people to remember, the quality of the memories may be limited. We may remember what something looked like more clearly, but this could be at the expense of other types of information. One study showed that while photos could help people remember what they saw during some event, they <a href="https://journals.sagepub.com/doi/abs/10.1177/0956797617694868">reduced their memory of what was said</a>.</p> <h2>Identity distortions?</h2> <p>There are some rather profound risks when it comes to personal memory. Our identity is a product of our life experiences, which can be easily accessed through our memories of the past. So, does constant photographic documentation of life experiences alter how we see ourselves? There is no substantial empirical evidence on this yet, but I would speculate that it does.</p> <p>Too many images are likely to make us remember the past in a fixed way – blocking other memories. While it is <a href="https://theconversation.com/what-is-your-first-memory-and-did-it-ever-really-happen-95953">not uncommon for early childhood memories</a> to be based on photos rather than the actual events, these are not always true memories.</p> <p>Another issue is the fact that research has uncovered <a href="https://www.sciencedirect.com/science/article/pii/S0747563216302503;%20http://www.vulture.com/2014/01/history-of-the-selfie.html">a lack of spontaneity in selfies</a> and many other photos. They are planned, the poses are not natural and at times the image of the person is distorted. They also reflect a narcissistic tendency which shapes the face in unnatural mimics – artificial big smiles, sensual pouts, funny faces or offensive gestures.</p> <p>Importantly, selfies and many other photos are also <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5318447/">public displays</a> of specific attitudes, intentions and stances. In other words, they do not really reflect who we are, they reflect what we want to show to others about ourselves at the moment. If we rely heavily on photos when remembering our past, we may create a distorted self identity based on the image we wanted to promote to others.</p> <p>That said, our natural memory isn’t actually perfectly accurate. Research shows that we often <a href="https://theconversation.com/the-real-you-is-a-myth-we-constantly-create-false-memories-to-achieve-the-identity-we-want-103253">create false memories about the past</a>. We do this in order to maintain the identity that we want to have over time – and avoid conflicting narratives about who we are. So if you have always been rather soft and kind – but through some significant life experience decide you are tough – you may dig up memories of being aggressive in the past or even completely make them up.</p> <p>Having multiple daily memory reports on the phone of how we were in the past might therefore render our memory less malleable and less adaptable to the changes brought about by life – making our identity more stable and fixed.</p> <p>But this can create problems if our present identity becomes different from our fixed, past one. That is an uncomfortable experience and exactly what the “normal” functioning of memory is aimed to avoid – it is malleable so that we can have a non-contradictory narrative about ourselves. We want to think of ourselves as having a certain unchanging “core”. If we feel unable to change how we see ourselves over time, this could seriously affect our sense of agency and mental health.</p> <p>So our obsession with taking photos may be causing both memory loss and uncomfortable identity discrepancies.</p> <p>It is interesting to think about how technology changes the way we behave and function. As long as we are aware of the risks, we can probably mitigate harmful effects. The possibility that actually sends shivers to my spine is that we lose all those precious pictures because of some widespread malfunctioning of our smart phones.</p> <p>So the next time you’re at a museum, do take a moment to look up and experience it all. Just in case those photos go missing.<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/109285/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/giuliana-mazzoni-175429">Giuliana Mazzoni</a>, Professor of Psychology, <a href="https://theconversation.com/institutions/university-of-hull-1191">University of Hull</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

The sense of <a href="https://www.tandfonline.com/doi/full/10.1080/09658211.2013.876048?casa_token=wqShWbRXJaYAAAAA%3AqJabgHtEbPtEQp7qHnl7wOb527bpGxzIJ_JwQX8eAyq1IrM_HQFIng8ELAMyuoFoeZyiX1zeJTPf">smell</a> is closely linked to the limbic system in the brain responsible for emotion and memory making food-related memories particularly vivid and emotionally charged.</p> <p>But, food-evoked nostalgia can also give rise to <a href="https://onlinelibrary.wiley.com/doi/full/10.1002/hpja.873">negative memories</a>, such as of being forced to eat a certain vegetable you disliked as a child, or a food eaten during a sad moment like a loved ones funeral. Understanding why these foods <a href="https://www.tandfonline.com/doi/full/10.1080/02699931.2022.2142525?casa_token=16kAPHUQTukAAAAA%3A9IDvre8yUT8UsuiR_ltsG-3qgE2sdkIFgcrdH3T5EYbVEP9JZwPcsbmsPLT6Kch5EFFs9RPsMTNn">evoke negative memories</a> could help us process and overcome some of our adult food aversions. Encountering these foods in a positive light may help us reframe the memory associated with them.</p> <h2>What people told us about food and nostalgia</h2> <p>Recently <a href="https://onlinelibrary.wiley.com/doi/full/10.1002/hpja.873">we interviewed eight Australians</a> and asked them about their experiences with food-evoked nostalgia and the influence on their mood. We wanted to find out whether they experienced food-evoked nostalgia and if so, what foods triggered pleasant and unpleasant memories and feelings for them.</p> <p>They reported they could use foods that were linked to times in their past to manipulate and influence their mood. Common foods they described as particularly nostalgia triggering were homemade meals, foods from school camp, cultural and ethnic foods, childhood favourites, comfort foods, special treats and snacks they were allowed as children, and holiday or celebration foods. One participant commented:</p> <blockquote> <p>I guess part of this nostalgia is maybe […] The healing qualities that food has in mental wellbeing. I think food heals for us.</p> </blockquote> <p>Another explained</p> <blockquote> <p>I feel really happy, and I guess fortunate to have these kinds of foods that I can turn to, and they have these memories, and I love the feeling of nostalgia and reminiscing and things that remind me of good times.</p> </blockquote> <p>Understanding food-evoked nostalgia is valuable because it provides us with an insight into how our sensory experiences and emotions intertwine with our memories and identity. While we know a lot about how food triggers nostalgic memories, there is still much to learn about the specific brain areas involved and the differences in food-evoked nostalgia in different cultures.</p> <p>In the future we may be able to use the science behind food-evoked nostalgia to help people experiencing dementia to tap into lost memories or in psychological therapy to help people reframe negative experiences.</p> <p>So, if you are ever feeling a little down and want to improve your mood, consider turning to one of your favourite comfort foods that remind you of home, your loved ones or a holiday long ago. Transporting yourself back to those times could help turn things around.<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/232826/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/megan-lee-490875">Megan Lee</a>, Senior Teaching Fellow, Psychology, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a>; <a href="https://theconversation.com/profiles/doug-angus-1542552">Doug Angus</a>, Assistant Professor of Psychology, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a>, and <a href="https://theconversation.com/profiles/kate-simpson-1542551">Kate Simpson</a>, Sessional academic, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Still fab after 60 years: how The Beatles’ A Hard Day’s Night made pop cinema history

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/alison-blair-223267">Alison Blair</a>, <a href="https://theconversation.com/institutions/university-of-otago-1304">University of Otago</a></em></p> <p>I first saw A Hard Day’s Night at a film festival over 20 years ago, at the insistence of my mum. By then, it was already decades old, but I remember being enthralled by its high-spirited energy.</p> <p>A Beatles fan, mum had introduced me to the band’s records in my childhood. At home, we listened to Please Please Me, the band’s 1963 single, and the Rubber Soul album from 1965, which I loved.</p> <p>Television regularly showed old black-and-white scenes of Beatlemania that, to a ten-year-old in the neon-lit 1980s, seemed like ancient history. But then, I’d never seen a full-length Beatles film. I had no idea what I was in for.</p> <p>When the lights went down at Dunedin’s Regent Theatre, the opening chord of the film’s title song announced its intentions: an explosion of youthful vitality, rhythmic visuals, comical high jinks and the electrifying thrill of Beatlemania in 1964.</p> <p>This time, it didn’t seem ancient at all.</p> <p>Since that first viewing, I’ve returned to A Hard Day’s Night again and again. I now show it to my students as a historically significant example of pop music film making – visually inventive cinema, emblematic of a fresh era in youth culture, popular music and fandom.</p> <h2>Beatlemania on celluloid</h2> <p>A musical comedy depicting a chaotic 36 hours in the life of the Beatles, A Hard Day’s Night has now reached its 60th anniversary.</p> <p>Directed by <a href="https://www.imdb.com/name/nm0504513/">Richard Lester</a>, the film premiered in London on July 6 1964, with its first public screening a day later (incidentally, also Ringo Starr’s birthday), and the <a href="https://www.discogs.com/master/24003-The-Beatles-A-Hard-Days-Night">album of the same name</a> released on July 10.</p> <p>The band’s popularity was by then reaching dizzying heights of hysteria, all reflected in the film. The Beatles are chased by hordes of fans, take a train trip, appear on TV, run from the police in a Keystone Cops-style sequence, and play a televised concert in front of screaming real-life Beatles fans.</p> <p>Side one of the album provides the soundtrack, and the film inspired pop music film and video from then on, from the <a href="https://www.imdb.com/title/tt0060010/">Monkees TV series</a> (1966–68) to the Spice Girls’ <a href="https://www.imdb.com/title/tt0120185/">Spice World</a> (1997) and music videos as we know them today.</p> <h2>The original music video</h2> <p>Postwar teen culture and consumerism had been on the rise since the 1950s. In 1960s Britain, youth music TV programmes, notably <a href="https://www.imdb.com/title/tt0196287/">Ready Steady Go!</a> (1963–66), meant pop music now had a developing visual culture.</p> <p>The youthful zest and vitality of ‘60s London was reflected in the pop-cultural sensibility, modern satirical humour and crisp visual impact of A Hard Day’s Night.</p> <p>Influenced by <a href="https://nofilmschool.com/french-new-wave-cinema">French New Wave</a> film making, and particularly the early 1960s work of <a href="https://www.imdb.com/name/nm0000419/">Jean-Luc Godard</a>, A Hard Day’s Night employs <em><a href="https://indiefilmhustle.com/cinema-verite/">cinéma vérité</a></em>-style hand-held cinematography, brisk jump cuts, unusual framing and dynamic angles, high-spirited action, and a self-referential nonchalance.</p> <p>The film also breaks the “fourth wall”, with characters directly addressing the audience in closeup, and reveals the apparatus of the visual performance of music: cameras and TV monitors are all part of the frame.</p> <p>Cutting the shots to the beat of the music – as in the Can’t Buy Me Love sequence – lends a visual rhythm that would later become the norm in music video editing. Lester developed this technique further in the second Beatles film, <a href="https://www.imdb.com/title/tt0059260/">Help!</a> (1965).</p> <p>The closing sequence of A Hard Day’s Night is possibly the film’s most dynamic: photographic images of the band edited to the beat in the style of stop-motion animation. Sixty years on, it still feels fresh, especially as so much contemporary film making remains hidebound by formulaic Hollywood rules.</p> <figure class="align-center "><img src="https://images.theconversation.com/files/604790/original/file-20240704-17-ov77mn.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/604790/original/file-20240704-17-ov77mn.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=453&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/604790/original/file-20240704-17-ov77mn.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=453&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/604790/original/file-20240704-17-ov77mn.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=453&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/604790/original/file-20240704-17-ov77mn.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=569&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/604790/original/file-20240704-17-ov77mn.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=569&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/604790/original/file-20240704-17-ov77mn.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=569&amp;fit=crop&amp;dpr=3 2262w" alt="A Hard Day's Night movie poster" /><figcaption><span class="caption">A new pop aesthetic: original film poster for A Hard Day’s Night.</span> <span class="attribution"><span class="source">Getty Images</span></span></figcaption></figure> <h2>Slapstick and class awareness</h2> <p>As with much popular culture from the past, the humour in A Hard Day’s Night doesn’t always doesn’t land the way it would have in 1964. And yet, there are moments that seem surprisingly modern in their razor-sharp irony.</p> <p>In particular, the band’s Liverpudlian working-class-lad jibes and chaotic energy contrast brilliantly with the film’s upper-class characters. Actor Victor Spinetti’s comically over-anxious TV director, constantly hand-wringing over the boys’ rebelliousness, underscores the era-defining change the Beatles represented.</p> <p>Corporate pop-culture consumerism is also satirised. John Lennon “snorts” from a Coca-Cola bottle, a moment so knowingly silly it registers as more contemporary than it really is. George Harrison deflects a journalist’s banal questions with scathingly witty answers, and cuts a fashion company down to size by describing their shirt designs as “grotesque”.</p> <p>And there is Paul McCartney’s running joke that his grandfather – played by Wilfred Brambell from groundbreaking sitcom <a href="https://www.imdb.com/title/tt0057785/">Steptoe and Son</a> (1962–74) – is “very clean”.</p> <p>Even the film’s old-fashioned visual slapstick still holds up in 2024. Showing the film to this year’s students, I didn’t expect quite as much laughter when Ringo’s attempts to be chivalrous result in a fall-down-a-hole mishap.</p> <p>In 2022, the <a href="https://www.criterion.com/">Criterion Collection</a> released a high-resolution restoration of the film, so today A Hard Day’s Night can be seen in all its fresh, black-and-white, youthful vigour.</p> <p>Happy 60th, A Hard Day’s Night. And happy 84th, Ringo. Both still as lively and energetic as ever.<!-- Below is The Conversation's page counter tag.

Married at First Sight groom dies at just 33

<p>Former <em>Married At First Sight NZ</em> contestant Andrew Jury has died at the age of 33. </p> <p>The Auckland-based builder passed away in recent weeks, as his untimely death was announced by two of his former <em>MAFS</em> contestants. </p> <p>“It’s with the heaviest hearts we’ve come together to acknowledge the passing of Andrew Jury,” former <em>MAFS NZ</em> stars Brett and Angel Renall, and Benjamin Blackwell wrote in a joint statement, according to the <em><a href="https://www.nzherald.co.nz/entertainment/married-at-first-sight-nz-groom-andrew-jury-dies/47OQFBCORZHARPILFOEA65N7SE/" target="_blank" rel="noopener">New Zealand Herald</a>.</em></p> <p>“We had the absolute pleasure of filming and participating in a show which leaves us intricately linked for a lifetime."</p> <p>“Despite his struggles, Andrew was always friendly and the life of the party during our shared experience, and he really valued his time on the show."</p> <p>“At this time, our entire cast wishes to send our deepest condolences and love to his family.”</p> <p>On Sunday, Warner Bros Discovery, broadcaster of <em>MAFS NZ</em>, released a statement about the death.</p> <p>“WBD takes duty of care extremely seriously and has protocols in place regarding the wellbeing of cast and crew,” a spokesperson of the company said.</p> <p>"All <em>MAFS NZ</em> contributors have access to mental health professionals throughout the process, including pre-screening, during production and after broadcast."</p> <p>Jury appeared on the first season of <em>Married At First Sight NZ</em>, which aired in 2017. </p> <p>During his time on the show, he was matched with Vicky Gleeson-Stokes, but the pair were not a perfect fit and did not make it to final vows.</p> <p>Following his appearance on the show, Jury was heavily critical of the TV programme and urged others not to audition. </p> <p>The final straw for the builder, who was 26 at the time, was when local sex worker Lisa Lewis announced she had been short-listed to appear in the season after Jury’s.</p> <p>“It’s unethical how they’re going about these things,” he told the <a href="https://www.nzherald.co.nz/entertainment/married-at-first-sight-star-andrew-jury-bags-show-and-warns-other-kiwis-from-applying-after-lisa-lewis-announcement/QULDBF6S4SHDOEOBUSZIPY3FXU/#:~:text=%22It's%20unethical%20how%20they're,%22experts%22%20to%20match%20couples." target="_blank" rel="noopener"><em>New Zealand Herald</em> </a>at the time. “You can’t get an escort on this show. You can’t do that to a guy.”</p> <p>The former contestant said he and his fellow participants were hopeful in finding love when going on the show, but he believed it was all a stitch-up from day one.</p> <p>“They [the contestants] are the most amazing people on the show, they put their hearts on the line and they all got burned,” he continued.</p> <p>“I make great TV, but my wife and me were not matched in the slightest. She’s a princess, I’m a bogan. How can they say it’s a legit process when you get the complete opposite of what you want?”</p> <p><em>Image credits: Instagram </em></p>

5 ways to fake a clean bathroom

<p>Got a friend popping around for a catch up, and, your bathroom is less than sparkling? Don’t stress. Follow our foolproof tips to fake it so no one knows you didn’t have time to do a proper clean.</p> <p><strong>1. Scrub the loo</strong></p> <p>The toilet is often a telltale sign that your bathroom is in need of a clean. If you haven’t already invested in a leave-in cleaner for your bowl, simply get in there with some toilet cleaner and give a good squirt under the rim. Leave it to do its job while you get on with the rest of the bathroom. </p> <p>Then when it’s had a few minutes to soak, give it a once over with the toilet brush. Grab some toilet paper (or an antibacterial wipe) and give the rim and the top of the toilet a once over to remove any dust.</p> <p><strong>2. Eliminate any obvious mould and grime</strong></p> <p>Find yourself some good-quality mould spray that you can apply and then leave to work its magic while you move on to other areas of the bathroom. After 10 minutes (check your packet for the optimal time) you should be able to spray it with warm water from the shower and then wipe it clean.</p> <p><strong>3. Do a quick dust bust</strong></p> <p>Grab yourself a clean cloth or antibacterial wipe and go over the shelves and basin to get rid of any dust or dirt you can see.</p> <p><strong>4.Change your bathmat and hand towel</strong></p> <p>There’s nothing like a fresh and clean bathmat to trick your guests into thinking that you’ve just finished scrubbing the bathroom. Add a clean hand towel to complete the look.</p> <p><strong>5.Add a sweet scent</strong></p> <p>Give your bathroom a look of freshness by popping a small vase of flowers in there. You can also try a scented candle on top of the toilet to give off a nice scent and hide any odours.</p> <p><em>Image credits: Shutterstock</em></p>

"Ruined our trip": Mum shell-shocked by $130k fine

<p>A mother has been slapped with a hefty fine after her children were caught in a seemingly innocent act while on a beach holiday. </p> <p>Charlotte Russ took her five kids on a trip to Pismo Beach in California, where her children started enthusiastically collecting what they thought were ordinary seashells. </p> <p>"My kids they thought they were collecting seashells, but they were actually collecting clams, 72 to be exact,"  Russ told local news outlet <em><a href="https://abc7.com/post/fresno-woman-fined-88k-after-kids-collect-clams/14859295/" target="_blank" rel="nofollow noreferrer noopener">ABC 7</a></em>.</p> <p>Clamming is highly regulated in California, meaning if you don't have a fishing license, you cannot catch the small sea creatures. </p> <p>She received a citation right there on the beach and was later notified she has to pay close to $89,000, or $133,000 AUD, for her kids' seemingly innocent treasure hunt. </p> <p>"It made me really sad and depressed, and it kind of ruined our trip," said Russ.</p> <p>Department of Fish and Wildlife's Lieutenant Matthew Gil defended the fine, saying there are rules in place for a reason. </p> <p>"The reason we got it we have these regulations is because we have to let them get to 4 and a half inches so they can spawn so they can have they can have offspring every year, and they have juvenile clams," said Lt. Gil.</p> <p>Russ said her kids have learned their lesson, saying, "They know now at the beach don't touch anything, but they know now what a clam is, compared to what a seashell is now, I've had to explain that to them."</p> <p>The mother was able to plead her case with a San Luis Obispo County Judge, who reduced her fine to $500 dollars, and after she "won" her case, Russ got a shellfish tattoo to commemorate the incident.</p> <p>"It was definitely one expensive trip to Pismo, unforgettable," said Russ.</p> <p><em>Image credits: ABC 7</em></p>

10 tips for a better night’s sleep in a hotel room

<p>From noisy neighbours to unbearable bedding, a good night’s sleep in a hotel room can be hard to come by. Here are 10 tips to help you get decent shut eye.</p> <p><strong>1. Book a room midway down a hallway</strong></p> <p>This is generally the quietest part of the floor, way from ice and wending machines, laundry facilities, exits, closets and any other places where sudden noises might occur.</p> <p><strong>2. Try to avoid rooms facing a pool</strong></p> <p>While the view is something to admire, pools can also be the sight of noise generating late-night gathering and any sounds generally echo loudly off the water.</p> <p><strong>3. Inquire at the front desk about pillow options</strong></p> <p>If the wrong pillow gives you back or neck pain have a chat to the front desk when checking in. Most hotels stock pillows of varying firmness, and can offer a better fit.</p> <p><strong>4. Pack earplugs and eyeshades</strong></p> <p>When you’re struggling to get to sleep the tiniest noise or ray of light can end up being a huge distraction. Nip this in the bud by packing earplugs and eyeshades.</p> <p><strong>5. Turn your mobile phone off</strong></p> <p>Mobile notifications can be a huge distraction (particularly when they’re coming from friends and family in different time zones). Turn your phone off, and enjoy the bliss. </p> <p><strong>6. Make use of your ‘do not disturb’ sign</strong></p> <p>If you’re planning to sleep in make sure you put your ‘do not disturb’ sign on the outside doorknob, otherwise you might get a rude awakening from a housekeeper.</p> <p><strong>7. Report any noises immediately</strong></p> <p>Sometimes a quick pound of the wall will quiet down a noisy neighbour, but this doesn’t always work. If the people in the room next to you won’t keep quiet, make sure you let the front desk know and they can take the necessary actions.</p> <p><strong>8. Adjust the room temperature</strong></p> <p>Most people sleep better in a cooler room, so make sure you adjust the temperature to whatever is the best fit for you to get sleep. Even just opening the window a tiny little crack can make a big difference in terms of your overall comfort levels.</p> <p><strong>9. Ask the front desk about blackout shades</strong></p> <p>Particularly if you’re staying in a city that’s full of lights, noises and distractions, blackout shades can provide you with a level of peace and comfort that will help you sleep.</p> <p><strong>10. Consider bringing your own sheets</strong></p> <p>Particularly if you’ve got skin sensitives, it’s generally a good idea to bring your own sheets (if you’ve got enough space). The familiar scent and feel will really help you sleep.</p> <p><em>Image credits: Shutterstock</em></p>
