But the virus, SARS-CoV-2, is still around, and for many people the effects of an infection can be long-lasting. When symptoms persist for more than three months after the initial COVID infection, this is generally referred to as <a href="https://www.who.int/europe/news-room/fact-sheets/item/post-covid-19-condition">long COVID</a>. In September, Grammy-winning Brazilian musician <a href="https://www.abc.net.au/news/2024-09-07/brazilian-musician-sergio-mendez-dies-at-83/104323360">Sérgio Mendes</a> died aged 83 after reportedly having long COVID. <a href="https://www.abs.gov.au/articles/covid-19-mortality-australia-deaths-registered-until-31-july-2023">Australian data</a> show 196 deaths were due to the long-term effects of COVID from the beginning of the pandemic up to the end of July 2023. In the United States, the Centers for Disease Control and Prevention reported 3,544 <a href="https://www.cdc.gov/nchs/pressroom/nchs_press_releases/2022/20221214.htm">long-COVID-related deaths</a> from the start of the pandemic up to the end of June 2022. The symptoms of <a href="https://www.healthdirect.gov.au/long-covid">long COVID</a> – such as fatigue, shortness of breath and “brain fog” – can be debilitating. But can you die from long COVID? The answer is not so simple. <h2>How could long COVID lead to death?</h2> There’s still a lot we don’t understand about what causes long COVID. A popular theory is that “zombie” <a href="https://www.pnas.org/doi/full/10.1073/pnas.2300644120">virus fragments</a> may linger in the body and cause inflammation even after the virus has gone, resulting in long-term health problems. Recent research suggests a reservoir of <a href="https://www.sciencedirect.com/science/article/abs/pii/S1198743X24004324?via%3Dihub">SARS-CoV-2 proteins</a> in the blood might explain why some people experience ongoing symptoms. We know a serious COVID infection can damage <a href="https://covid19.nih.gov/news-and-stories/long-term-effects-sars-cov-2-organs-and-energy#:%7E:text=What%20you%20need%20to%20know,main%20source%20of%20this%20damage">multiple organs</a>. For example, severe COVID can lead to <a href="https://www.hopkinsmedicine.org/health/conditions-and-diseases/coronavirus/covid-long-haulers-long-term-effects-of-covid19">permanent lung dysfunction</a>, persistent heart inflammation, neurological damage and long-term kidney disease. These issues can in some cases lead to death, either immediately or months or years down the track. But is death beyond the acute phase of infection from one of these causes the direct result of COVID, long COVID, or something else? Whether long COVID can directly cause death continues to be a topic of debate. Of the <a href="https://www.cdc.gov/nchs/data/vsrr/vsrr025.pdf">3,544 deaths</a> related to long COVID in the US up to June 2022, the most commonly recorded underlying cause was COVID itself (67.5%). This could mean they died as a result of one of the long-term effects of a COVID infection, such as those mentioned above. COVID infection was followed by heart disease (8.6%), cancer (2.9%), Alzheimer’s disease (2.7%), lung disease (2.5%), diabetes (2%) and stroke (1.8%). Adults aged 75–84 had the highest rate of death related to long COVID (28.8%). These findings suggest many of these people died “with” long COVID, rather than from the condition. In other words, long COVID may not be a direct driver of death, but rather a contributor, likely exacerbating existing conditions. <h2>‘Cause of death’ is difficult to define</h2> Long COVID is a relatively recent phenomenon, so mortality data for people with this condition are limited. However, we can draw some insights from the experiences of people with post-viral conditions that have been studied for longer, such as myalgic encephalomyelitis or chronic fatigue syndrome (ME/CFS). Like long COVID, <a href="https://bmjopen.bmj.com/content/12/5/e058128">ME/CFS</a> is a complex condition which can have significant and varied effects on a person’s physical fitness, nutritional status, social engagement, mental health and quality of life. Some research indicates people with ME/CFS are at <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5218818/">increased risk</a> of dying from causes including heart conditions, infections and suicide, that may be triggered or compounded by the debilitating nature of the syndrome. So what is the emerging data on long COVID telling us about the potential increased risk of death? Research from 2023 has suggested adults in the US with long COVID were at <a href="https://jamanetwork.com/journals/jama-health-forum/fullarticle/2802095">greater risk</a> of developing heart disease, stroke, lung disease and asthma. Research has also found <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9721155/">long COVID</a> is associated with a higher risk of <a href="https://www.tandfonline.com/doi/full/10.1080/21642850.2022.2164498#abstract">suicidal ideation</a> (thinking about or planning suicide). This may reflect common symptoms and consequences of long COVID such as sleep problems, fatigue, chronic pain and emotional distress. But long COVID is more likely to occur in people who have <a href="https://www.aihw.gov.au/reports/covid-19/long-covid-in-australia-a-review-of-the-literature/summary">existing health conditions</a>. This makes it challenging to accurately determine how much long COVID contributes to a person’s death. Research has long revealed <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7302107/">reliability issues</a> in cause-of-death reporting, particularly for people with chronic illness. <h2>So what can we conclude?</h2> Ultimately, long COVID is a <a href="https://www.health.gov.au/topics/chronic-conditions/about-chronic-conditions">chronic condition</a> that can significantly affect quality of life, mental wellbeing and overall health. While long COVID is not usually immediately or directly life-threatening, it’s possible it could exacerbate existing conditions, and play a role in a person’s death in this way. Importantly, many people with long COVID around the world lack access to appropriate support. We need to develop <a href="https://www.mja.com.au/journal/2024/221/9/persistent-symptoms-after-covid-19-australian-stratified-random-health-survey">models of care</a> for the optimal management of people with long COVID with a focus on multidisciplinary care.

No time for a holiday? A ‘workation’ could be the answer

<a href="https://theconversation.com/profiles/mariachiara-barzotto-1449459">Mariachiara Barzotto</a>, <a href="https://theconversation.com/institutions/university-of-bath-1325">University of Bath</a> Imagine this: you’re lounging on the beach, waves crashing in the background. A laptop sits on the table next to your iced coffee. In between meetings, you dip into the ocean or explore a hiking trail. This is the ideal vision of “workations” – a blend of work and vacation that is <a href="https://www.peoplemanagement.co.uk/article/1882649/rise-workation-hr-encourage-blurring-lines-home-away#:%7E:text=Since%20many%20people%20shifted%20to,having%20to%20take%20annual%20leave.">gaining popularity</a> worldwide. A workation allows employees to work remotely from a holiday spot, and is part of a larger shift towards more flexible working arrangements, accelerated by the COVID pandemic and the rise of digital technology. <a href="https://www.tandfonline.com/doi/full/10.1080/16078055.2022.2134199#d1e474">Workations</a> can last from a few days to several weeks. The concept can be appealing to both employees and companies, but there are challenges too. So, understanding its benefits and limitations is important for workers and employers alike. The most obvious benefit for employees is enjoying a new environment while staying productive. The typical work environment can become monotonous, potentially leading to burnout, decreased creativity and dissatisfaction. A workation offers an escape from this day-to-day grind, providing a refreshing change of scenery. It combines the mental break of a vacation with the flexibility of working remotely, allowing workers to balance their professional and personal lives and <a href="https://www.jstage.jst.go.jp/article/abas/20/1/20_0210112a/_pdf">enhance their creativity</a>. This flexibility may be particularly beneficial for those with high workloads or tight schedules, as they no longer need to sacrifice time away from work to relax. And companies can also reap rewards from approving workations among their staff. One of the most significant advantages is employee retention. Flexible work arrangements are among <a href="https://buffer.com/state-of-remote-work/2023">the top priorities</a> for employees in today’s job market, helping to reduce staff turnover. Offering the option of a workation could also make a company more attractive to prospective employees. And workers who are free to work from inspiring locations may return to their tasks less stressed, and more motivated and engaged. Studies show that remote workers often demonstrate <a href="https://journals.sagepub.com/doi/full/10.1177/1529100615593273">increased organisational commitment</a>. Another advantage is the potential for cost savings. With more employees working remotely, companies may reduce their need for large office spaces or the expensive perks offered in corporate environments such as gyms, canteens and the staffing that goes with them. But there can be challenges too. The boundary between work and leisure can become blurred, and some employees may find it <a href="https://tuprints.ulb.tu-darmstadt.de/7578/1/Dissertation_Reinke_Always%20Online%20-%20Boundary%20Management%20and%20Well-being.pdf%20">hard to disconnect from work</a> – defeating the object of travelling to a different workplace. The allure of finishing “just one more task” can prevent employees from truly enjoying their surroundings, potentially leading to exhaustion instead of rejuvenation. Time zone differences can also be a challenge. Juggling meetings and collaborating with colleagues in different time zones can lead to irregular work hours that make it hard to maintain a healthy work-life balance. Distractions are another concern. Beaches, tourist attractions or even the simple novelty of being in a new place can make it difficult to focus on work tasks. Employees need to have a strong sense of discipline to remain productive. For companies, one of the primary challenges is ensuring that employees remain productive. Monitoring performance without feeling intrusive can be a tricky balance for managers to strike. Security is another major concern. Remote work often involves accessing company networks and handling sensitive information. When employees work from unfamiliar locations – particularly in public spaces such as cafes – there may be increased risks related to cybersecurity. Ensuring that employees follow security protocols, use secure wifi and protect sensitive data is crucial. Lastly, workations might not be feasible for all roles. This can lead to disparities in who can take advantage of the opportunity, potentially leading to bad feeling among other staff. For the concept of workations to succeed, both employees and employers should set clear expectations, establish boundaries, and focus on maintaining productivity while allowing time for relaxation. But, if managed properly, they could become a staple of modern work culture. In a world where flexibility and wellbeing are increasingly valued, workations offer a unique opportunity to blend productivity with personal fulfilment, reshaping how we think about work and leisure. <h2>Nine tips for having a successful workation</h2> 1. Choose the right destination Opt for a location with reliable internet access and where the time difference between colleagues and clients is manageable. 2. Set clear boundaries Establish dividing lines between your work and vacation time, and communicate these boundaries with your employer and colleagues. 3. Ensure you have the right tech set-up Bring all the necessary equipment, including noise-cancelling headphones. Double-check that you have remote access to all necessary material before leaving. 4. Plan for cybersecurity Use a secure virtual private network (VPN) to protect company data, and follow your company’s cybersecurity policies to the letter. 5. Understand your company’s remote work policy Read up on things like flexibility in terms of location, time zones, working hours and refunds for co-working spaces or tech tools. 6. Set realistic expectations Don’t expect your workation to feel like a full vacation. Plan your leisure activities around your work schedule. Be prepared to work longer or odd hours if your company operates in a different time zone. 7. Consider the local infrastructure Research amenities such as medical services, food delivery and transport. These might be important if you stay in a more remote or unfamiliar area. Have a contingency plan for health emergencies and check visa requirements. 8. Prepare for flexibility Be ready for unexpected issues like slow internet or disruptions due to local events. Back-up plans, such as access to a co-working space or alternative accommodation, can save you from unnecessary stress. 9. Stay organised Keep a work schedule and a checklist of tasks to ensure that you remain as productive as you are in your regular work environment.<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/240485/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/mariachiara-barzotto-1449459">Mariachiara Barzotto</a>, Senior Lecturer in Management Strategy and Organisation, <a href="https://theconversation.com/institutions/university-of-bath-1325">University of Bath</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Travel Tips

Crowds, water guns and protests: could ‘slow tourism’ be the answer to an overtourism backlash?

<a href="https://theconversation.com/profiles/amy-errmann-1360032">Amy Errmann</a>, <a href="https://theconversation.com/institutions/auckland-university-of-technology-1137">Auckland University of Technology</a> With overtourism in the spotlight as the travel industry continues to rebound after the pandemic, popular destinations around the world are feeling the strain. Bali is overwhelmed by <a href="https://thebalisun.com/concerns-increasing-about-impact-of-trash-and-traffic-on-bali-tourists/">waste and traffic</a>, Australia’s sacred sites have suffered <a href="https://www.bbc.com/news/world-australia-50151344">environmental damage</a>, New York is facing rising rents <a href="https://www.theguardian.com/us-news/2023/oct/23/new-york-airbnb-crackdown-rules-housing">due to short-term rentals</a>, and Singapore’s scenic spots are becoming <a href="https://www.channelnewsasia.com/singapore/overtourism-locals-tourists-sustainable-tourism-stb-focus-4517681">clogged with crowds</a>. Frustrated locals are pushing back – from <a href="https://www.nzherald.co.nz/travel/barcelona-locals-spray-tourists-with-water-guns-during-protest-over-housing-costs/FUFHXKO5X5F5NNPSU6ELNVGSIA/">spraying water at tourists </a>in Barcelona to <a href="https://adventure.com/venice-locals-squatting-against-overtourism-photography/">organising protests in Venice</a>. As the northern hemisphere high season ends, Aotearoa New Zealand is preparing for an influx of visitors ahead of its summer tourism season. And much like those other <a href="https://www.nytimes.com/2024/09/08/world/europe/greece-cruise-ships-tourists-islands.html">tourist hotspots</a>, the government is looking at how to manage the negative effects of tourism on local communities and the environment. This includes tripling the <a href="https://www.theguardian.com/world/article/2024/sep/04/new-zealand-to-nearly-triple-tourist-tax-for-international-visitors">international tourist tax</a> from NZ$35 to $100. The aim of the increase is to <a href="https://www.theguardian.com/world/2022/aug/11/new-zealand-tourism-minister-makes-pitch-to-the-rich-as-he-spurns-10-a-day-travellers">attract tourists</a> who are more mindful of their impact and willing to contribute to its mitigation, while also <a href="https://theconversation.com/welcome-to-nz-now-pay-up-the-risks-and-rewards-of-raising-the-foreign-tourist-tax-232138">reducing visitor numbers</a> to protect the country’s unique landscapes and cultures. But are there other ways the tourism industry can evolve to ensure benefits for both travellers and the communities they are visiting? So called “slow travel” could be the answer. <h2>Hunting the perfect photo</h2> Overtourism isn’t just about too many people in one place. It’s also about how people travel. <a href="https://edition.cnn.com/travel/social-media-tourism-effect-scn-wellness/index.html">Instagram-famous</a> landmarks draw massive crowds, <a href="https://www.rnz.co.nz/news/national/406195/visitors-ignore-ban-continue-to-visit-mermaid-pools-in-northland-hapu">disrupting local life</a> and sometimes even <a href="https://www.nzherald.co.nz/travel/vermot-town-famous-for-fall-foliage-bans-instagram-tourists-from-streets/BHKEYKKUTNHORFT6QCZ5TW333A/#google_vignette">leading to closures</a>. Travellers often pack their itineraries with as many sights as possible, racing from one place to another in a frenzy to capture the perfect photo. This hurried approach not only creates <a href="https://www.cntraveler.com/galleries/2015-06-19/barcelona-bhutan-places-that-limit-tourist-numbers">congestion</a> but also limits <a href="https://www.nature.com/articles/s41599-024-02859-z">meaningful engagement with the destination</a>. And it’s not just a numbers game. The way tourists behave also plays a critical role. A <a href="https://www.rnz.co.nz/national/programmes/ninetonoon/audio/2018690535/tropical-trash-the-impact-of-holidaying-in-the-pacific">2019 report</a> from the United Nations raised concerns about trash from tourists in developing small island states, including the Pacific Islands. According to the report, a tourist visiting these communities produced about 7kg of waste a day, compared to about 2.5kg produced by a local. The issue is not necessarily about travelling less, but about <a href="https://www.sciencedirect.com/science/article/pii/S2211973623000284">travelling more responsibly</a>. The tourism industry needs to be encouraging travel habits that allow both visitors and locals to enjoy tourism without compromising the integrity of the destination. <h2>The rise of slow travel</h2> Mindfulness – being fully present in the moment – has gained popularity since the 1970s. The concept has influenced a number of sectors, including <a href="https://slowfoodauckland.co.nz/">slow food</a>, <a href="https://ourwayoflife.co.nz/slow-fashion-101-what-to-buy-and-what-to-avoid-to-reduce-your-clothing-footprint/">slow fashion</a>, and now <a href="https://www.lakewanaka.co.nz/wanaka-stories/how-to-be-a-slow-mindful-traveler-in-wanaka/">slow travel</a>. It’s about <a href="https://link.springer.com/chapter/10.1007/978-3-031-63569-4_44#:%7E:text=Slow%20travel%2C%20mindful%20travel%2C%20or,spiritual%20well%2Dbeing%20of%20people">experiencing destinations</a> at a relaxed pace, focusing on deeper connections with local cultures and sustainability. This often means <a href="https://guestnewzealand.com/about-us/eco-travels-new-zealand/">staying longer in fewer places</a> and choosing eco-friendly transport. Understanding slow travel and mindfulness is important because they create <a href="https://www.forbes.com/sites/rogersands/2024/06/08/the-beauty-of-slow-travel/">richer, more memorable experiences</a>. Fast, <a href="https://www.sciencedirect.com/science/article/pii/S0261517724000487">hectic travel</a> often leaves little positive impact. Slow immersive travel, on the other hand, fosters lasting memories and reduces overtourism, pollution and cultural damage. <a href="https://www.tandfonline.com/doi/full/10.1080/00913367.2024.2325144">Research</a> shows when we consciously immerse ourselves in our surroundings we can have more meaningful experiences. Surprisingly, <a href="https://www.sciencedirect.com/science/article/pii/S0261517724000487">even luxury travel</a> – often dismissed as wasteful – can encourage respect and mindfulness for those who invest financially and mentally in their journey, unlike cheaper, mainstream tourism. Activities such as “<a href="https://www.sciencedirect.com/science/article/pii/S2666957921000197">forest bathing</a>”, <a href="https://www.visitutah.com/articles/mindful-hiking">hiking</a> or engaging with <a href="https://www.outofyourcomfortzone.net/a-guide-to-slow-travel-immersing-yourself-in-local-cultures/">local cultures</a> <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6723984/">boost wellbeing and meaning</a>, going beyond just “taking a photo for likes”. This mindful approach can <a href="https://www.sciencedirect.com/science/article/pii/S0160738321001419">change our behaviour on a personal level</a>. By focusing attention on fewer experiences, <a href="https://www.tandfonline.com/doi/full/10.1080/00913367.2024.2325144">travellers can heighten</a> their sense of awe and appreciation, making the travel more memorable. This idea is evident in “<a href="https://journals.sagepub.com/doi/abs/10.1177/002216786200200102?casa_token=PrIQTkCMjx0AAAAA:wtswfg0cuEuQec0zVg-Mbf9MuXYoqhQkWbaQCGdjxWkYUpVOwBu8Op5jC6V4nOghnow3xpwN3fDn">peak experiences</a>”. Disney, for example, creates <a href="https://ideaexchange.uakron.edu/docam/vol9/iss2/6/">emotionally-charged moments</a> that stick in visitors’ minds. Other experiences, such as “<a href="https://journals.sagepub.com/doi/full/10.1177/14614448211072808">digital detoxes</a>” or <a href="https://academic.oup.com/jcr/article-abstract/45/6/1142/4999270">pilgrimages</a> can leave a contemplative impression. By concentrating on a single aspect of a visit, it <a href="https://www.sciencedirect.com/science/article/pii/S0160738320300797?casa_token=Np4PXLk5RqsAAAAA:Q3440A-lsf-XTAWuboPPbIcnvBAhk8nnIoWyF-gynHkSPmyPaykzfpBhTLbFDBHZEX0bbtZJgQ">becomes special and memorable</a>. Even in busy places like Disneyland, focusing on one unique element can make the experience feel slower and more meaningful. <h2>The sustainability of tourism</h2> In the <a href="https://www.sciencedirect.com/science/article/pii/S0261517724000487">Faroe Islands</a>, slow travel helps protect local traditions and landscapes by encouraging thoughtful visitor behaviour, such as using local guides to minimise environmental impact. New Zealand can leverage its natural beauty to offer similar immersive experiences. <a href="https://www.nzherald.co.nz/travel/travel-well-what-is-mindful-hiking-walking-for-wellbeing-boost/67MYS6ZSNXC7ZH6OTZ2DLBGFL4/">Tramping</a> (hiking), for example, can promote a mindful connection with the environment. But even here, there needs to be a focus on balancing tourism with preservation. Popular spots, such as the Department of Conservation huts and the Te Araroa Trail, are <a href="https://www.wildernessmag.co.nz/te-araroa-trail-shows-pressure/">already becoming crowded</a>. It is essential to educate visitors on <a href="https://www.mpi.govt.nz/outdoor-activities/tramping-tips-to-prevent-spreading-pests-and-diseases/biosecurity-considerations-walking-and-tramping/">responsible practices</a> – such as cleaning equipment – to ensure they understand their <a href="https://www.doc.govt.nz/heritage-and-visitor-strategy#:%7E:text=The%20natural%2C%20cultural%20and%20historic,wellbeing%2C%20enabling%20communities%20to%20thrive.">role in protecting nature</a>. Travel that fosters a deeper appreciation for local cultures and environments benefits both visitors and the destinations they explore. The challenge is finding the right balance – encouraging meaningful travel experiences while still ensuring accessibility for all.<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/238316/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/amy-errmann-1360032">Amy Errmann</a>, Senior Lecturer, Marketing & International Business, <a href="https://theconversation.com/institutions/auckland-university-of-technology-1137">Auckland University of Technology</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Is social media making you unhappy? The answer is not so simple

<a href="https://theconversation.com/profiles/melissa-humphries-584274">Melissa Humphries</a>, <a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a> and <a href="https://theconversation.com/profiles/lewis-mitchell-266859">Lewis Mitchell</a>, <a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a> You may have seen headlines that link social media to sadness and depression. Social media use goes up, happiness goes down. But recent studies suggest those findings might not be so straightforward. Although it is true that people’s feelings of envy and depression are linked to high social media use, there is evidence to suggest social media use may not be causing that relationship. Instead, your mindset may be the biggest thing affecting how social media connects to your wellbeing. People who feel they are able to use social media, rather than social media “using them”, tend to gain more benefits from their online interactions. <h2>Why do people use social media?</h2> Social media covers a broad range of platforms: social networking, discussion forums, bookmarking and sharing content, disseminating news, exchanging media like photos and videos, and microblogging. These appeal to a wide range of users, from individuals of all ages through to massive businesses. For some, social media is a way to connect with people we may not otherwise see. In the United States, 39% of people say they <a href="https://www.americansurveycenter.org/research/the-state-of-american-friendship-change-challenges-and-loss">are friends with people they only interact with online</a>. For older people, this is especially important for increasing feelings of connectedness and wellbeing. Interestingly though, for older people, <a href="https://www.sciencedirect.com/science/article/pii/S0747563223004545">social media contact with family does not increase happiness</a>. Meanwhile, younger adults report increased happiness when they have more social media contact with family members. Teens, in particular, find social media most useful for <a href="https://www.pewresearch.org/internet/2022/11/16/connection-creativity-and-drama-teen-life-on-social-media-in-2022/">deepening connections and building their social networks</a>. With social media clearly playing such an important role in society, many researchers have tried to figure out: does it make us happier or not? <h2>Does social media make us happier?</h2> Studies have taken a variety of approaches, including asking people directly through surveys or looking at the content people post and seeing how positive or negative it is. One survey study from 2023 showed that as individuals’ social media use increased, <a href="https://www.researchgate.net/publication/372582895_The_Relationship_Between_Social_Media_Addiction_Happiness_and_Life_Satisfaction_in_Adults_Analysis_with_Machine_Learning_Approach">life satisfaction and happiness decreased</a>. Another found that <a href="https://www.tandfonline.com/doi/full/10.1080/0144929X.2023.2286529">less time on social media</a> was related to increases in work satisfaction, work engagement and positive mental health – so improved mental health and motivation at work. Comparing yourself to others on social media is connected to feelings of envy and depression. However, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9955439/">there is evidence</a> to suggest depression is the predictor, rather than the outcome, of both social comparison and envy. All this shows <a href="https://academic.oup.com/jcmc/article/29/1/zmad048/7612379?login=false">the way you feel about social media matters</a>. People who see themselves using social media rather than “being used” by it, tend to gain benefits from social media and not experience the harms. Interviews with young people (15–24 years) using social media suggest that positive mental health among that age group was influenced by <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8933808/">three features</a>: <ul> <li>connection with friends and their global community</li> <li>engagement with social media content</li> <li>the value of social media as an outlet for expression.</li> </ul> There are also studies that look at the emotions expressed by more frequent social media users. The so-called “<a href="https://epjdatascience.springeropen.com/articles/10.1140/epjds/s13688-017-0100-1">happiness paradox</a>” shows that most people think their friends on social media appear happier than themselves. This is a <a href="https://dl.acm.org/doi/10.1145/3110025.3110027">seeming impossibility</a> that arises because of <a href="https://www.nature.com/articles/srep04603">the mathematical properties</a> of how friendship networks work on social media. In one of our studies, Twitter content with recorded locations showed residents of cities in the United States that <a href="https://journals.plos.org/plosone/article/figure?id=10.1371/journal.pone.0064417.g007">tweeted more tended to express less happiness</a>. On the other hand, in Instagram direct messages, happiness has been found to be <a href="https://journals.sagepub.com/doi/full/10.1177/20563051241229655">four times more prevalent than sadness</a>. <h2>How does internet use in general affect our wellbeing?</h2> Some of the factors associated with decreased mental health are not aligned with social media use alone. <a href="https://journals.sagepub.com/doi/full/10.1177/0963721419838244">One recent study</a> shows that the path to decreased wellbeing is, at least partially, connected to digital media use overall (rather than social media use specifically). This can be due to sleep disruption, reduced face-to-face social interaction or physical activity, social comparison, and cyberbullying. None of these exist for social media alone. However, social media platforms are known to be driven by recommendation algorithms that may send us down “rabbit holes” of the same type of (increasingly extreme) content. This can lead to a distorted view of the world and our place in it. The important point here is to maintain a diverse and balanced information diet online. Interestingly, interacting on social media is not the only thing affecting our mental state. <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0090315">Rainfall influnces</a> the emotional content of social media posts of both the user experiencing rain, and parts of their extended network (even if they don’t experience rain!). This suggests that how we feel is influenced by the emotions in the posts we see. The good news is that happy posts are the most influential, with each happy post encouraging close to two additional happy updates from a user’s friends. The secret to online happiness therefore may not be to “delete your account” entirely (which, <a href="https://www.nature.com/articles/s41562-018-0510-5">as we have found</a>, may not even be effective), but to be mindful about what you consume online. And if you feel like social media is starting to use you, it might be time to change it up a bit.<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/232490/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/melissa-humphries-584274">Melissa Humphries</a>, Senior Lecturer, School of Computer and Mathematical Sciences, <a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a> and <a href="https://theconversation.com/profiles/lewis-mitchell-266859">Lewis Mitchell</a>, Professor of Data Science, <a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Do you have a mental illness? Why some people answer ‘yes’, even if they haven’t been diagnosed

<a href="https://theconversation.com/profiles/jesse-tse-1429151">Jesse Tse</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> and <a href="https://theconversation.com/profiles/nick-haslam-10182">Nick Haslam</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> Mental illnesses such as depression and anxiety disorders have become more prevalent, especially among <a href="https://www.aihw.gov.au/mental-health/overview/prevalence-and-impact-of-mental-illness#changeovertime">young people</a>. Demand for treatment is surging and prescriptions of some <a href="https://pubmed.ncbi.nlm.nih.gov/35176912/">psychiatric medications</a> have climbed. These upswinging prevalence trends are paralleled by rising public attention to mental illness. Mental health messages saturate traditional and social media. Organisations and governments are developing awareness, prevention and treatment initiatives with growing urgency. The mounting cultural focus on mental health has obvious benefits. It increases awareness, reduces stigma and promotes help-seeking. However, it may also have costs. Critics worry <a href="https://www.bacp.co.uk/bacp-journals/therapy-today/2023/april-2023/the-big-issue/">social media</a> sites are incubating mental illness and that ordinary unhappiness is being pathologised by the overuse of diagnostic concepts and “<a href="https://www.bustle.com/wellness/is-therapy-speak-making-us-selfish">therapy speak</a>”. British psychologist <a href="https://www.psych.ox.ac.uk/team/lucy-foulkes">Lucy Foulkes</a> argues the trends for rising attention and prevalence are linked. Her “<a href="https://www.sciencedirect.com/science/article/pii/S0732118X2300003X">prevalence inflation hypothesis</a>” proposes that increasing awareness of mental illness may lead some people to diagnose themselves inaccurately when they are experiencing relatively mild or transient problems. Foulkes’ hypothesis implies that some people develop overly broad concepts of mental illness. Our research supports this view. In a new study, <a href="https://www.sciencedirect.com/science/article/pii/S2666560324000318?via%3Dihub">we show</a> that concepts of mental illness have broadened in recent years – a phenomenon we call “<a href="https://www.tandfonline.com/doi/full/10.1080/1047840X.2016.1082418">concept creep</a>” – and that <a href="https://bmcpsychiatry.biomedcentral.com/articles/10.1186/s12888-023-05152-6">people differ</a> in the breadth of their concepts of mental illness. <h2>Why do people self-diagnose mental illnesses?</h2> In our new <a href="https://doi.org/10.1016/j.ssmmh.2024.100326">study</a>, we examined whether people with broad concepts of mental illness are, in fact, more likely to self-diagnose. We defined self-diagnosis as a person’s belief they have an illness, whether or not they have received the diagnosis from a professional. We assessed people as having a “broad concept of mental illness” if they judged a wide variety of experiences and behaviours to be disorders, including relatively mild conditions. We asked a nationally representative sample of 474 American adults if they believed they had a mental disorder and if they had received a diagnosis from a health professional. We also asked about other possible contributing factors and demographics. Mental illness was common in our sample: 42% reported they had a current self-diagnosed condition, a majority of whom had received it from a health professional. Unsurprisingly, the strongest predictor of reporting a diagnosis was experiencing relatively severe distress. The second most important factor after distress was having a broad concept of mental illness. When their levels of distress were the same, people with broad concepts were substantially more likely to report a current diagnosis. The graph below illustrates this effect. It divides the sample by levels of distress and shows the proportion of people at each level who report a current diagnosis. People with broad concepts of mental illness (the highest quarter of the sample) are represented by the dark blue line. People with narrow concepts of mental illness (the lowest quarter of the sample) are represented by the light blue line. People with broad concepts were much more likely to report having a mental illness, especially when their distress was relatively high. People with greater mental health literacy and less stigmatising attitudes were also more likely to report a diagnosis. Two interesting further findings emerged from our study. People who self-diagnosed but had not received a professional diagnosis tended to have broader illness concepts than those who had. In addition, younger and politically progressive people were more likely to report a diagnosis, consistent with some <a href="https://www.sciencedirect.com/science/article/pii/S2666560321000438">previous research</a>, and held broader concepts of mental illness. Their tendency to hold these more expansive concepts partially explained their higher rates of diagnosis. <h2>Why does it matter?</h2> Our findings support the idea that expansive concepts of mental illness promote self-diagnosis and may thereby increase the apparent prevalence of mental ill health. People who have a lower threshold for defining distress as a disorder are more likely to identify themselves as having a mental illness. Our findings do not directly show that people with broad concepts over-diagnose or those with narrow concepts under-diagnose. Nor do they prove that having broad concepts causes self-diagnosis or results in actual increases in mental illness. Nevertheless, the findings raise important concerns. First, they suggest that rising mental health awareness may <a href="https://www.newscientist.com/article/mg25934573-900-why-being-more-open-about-mental-health-could-be-making-us-feel-worse/">come at a cost</a>. In addition to boosting mental health literacy it may increase the likelihood of people incorrectly identifying their problems as pathologies. Inappropriate self-diagnosis can have adverse effects. Diagnostic labels may become identity-defining and self-limiting, as people come to believe their problems are enduring, <a href="https://www.sciencedirect.com/science/article/abs/pii/S0165032724002489?via%3Dihub">hard-to-control</a> aspects of who they are. Second, unwarranted self-diagnosis may lead people experiencing relatively mild levels of distress to seek help that is unnecessary, inappropriate and ineffective. Recent <a href="https://pubmed.ncbi.nlm.nih.gov/37844607/">Australian research</a> found people with relatively mild distress who received psychotherapy worsened more often than they improved. Third, these effects may be particularly problematic for young people. They are most liable to hold broad concepts of mental illness, in part due to <a href="https://www.sciencedirect.com/science/article/pii/S0010440X22000682?via%3Dihub">social media</a> <a href="https://www.tandfonline.com/doi/full/10.1080/10810730.2023.2235563">consumption</a>, and they experience mental ill health at relatively high and rising rates. Whether expansive concepts of illness play a role in the youth mental health crisis remains to be seen. Ongoing cultural shifts are fostering increasingly expansive definitions of mental illness. These shifts are likely to have mixed blessings. By normalising mental illness they may help to remove its stigma. However, by pathologising some forms of everyday distress, they may have an unintended downside. As we wrestle with the mental health crisis, it is crucial we find ways to increase awareness of mental ill health without inadvertently inflating it.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/231687/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/jesse-tse-1429151">Jesse Tse</a>, PhD Candidate at Melbourne School of Psychological Sciences, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> and <a href="https://theconversation.com/profiles/nick-haslam-10182">Nick Haslam</a>, Professor of Psychology, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Are some routes more prone to air turbulence? Will climate change make it worse? Your questions answered

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/doug-drury-1277871">Doug Drury</a>, <a href="https://theconversation.com/institutions/cquniversity-australia-2140">CQUniversity Australia</a> A little bit of turbulence is a common experience for air travellers. Severe incidents are rare – but when they occur they can be deadly. The recent Singapore Airlines flight SQ321 from London to Singapore shows the danger. An <a href="https://apnews.com/article/singapore-airlines-flight-turbulence-5a9a268e1a6a6fb9ece7e58b5ea9231b">encounter with extreme turbulence</a> during normal flight left one person dead from a presumed heart attack and several others badly injured. The flight diverted to land in Bangkok so the severely injured passengers could receive hospital treatment. Air turbulence can happen anywhere, but is far more common on some routes than on others. Climate change is expected to boost the chances of air turbulence, and make it more intense. In fact, <a href="https://www.nature.com/articles/s41586-019-1465-z">some research</a> indicates turbulence <a href="https://theconversation.com/aviation-turbulence-soared-by-up-to-55-as-the-world-warmed-new-research-207574">has already worsened</a> over the past few decades. <h2>Where does turbulence happen?</h2> Nearly every flight experiences turbulence in one form or another. If an aircraft is taking off or landing behind another aircraft, the wind generated by the engine and <a href="https://www.faa.gov/air_traffic/publications/atpubs/aim_html/chap7_section_4.html">wingtips</a> of the lead aircraft can cause “wake turbulence” for the one behind. Close to ground level, there may be turbulence due to strong winds associated with weather patterns moving through the area near an airport. At higher altitudes, there may be wake turbulence again (if flying close to another aircraft), or turbulence due to updraughts or downdraughts from a thunderstorm. Another kind of turbulence that occurs at higher altitudes is harder to predict or avoid. So-called “<a href="https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2023gl103814">clear-air turbulence</a>” is invisible, as the name suggests. It is often caused by warmer air rising into cooler air, and is generally expected to get worse due to climate change. At the most basic level turbulence is the result of two or more wind events colliding and creating eddies, or swirls of <a href="https://www.nationalgeographic.com/travel/article/what-is-turbulence-explained">disrupted airflow</a>. It often occurs near mountain ranges, as wind flowing over the terrain accelerates upward. Turbulence also often occurs at the edges of the <a href="https://www.nationalgeographic.com/travel/article/what-is-turbulence-explained">jet streams</a>. These are narrow bands of strong, high-altitude winds circling the globe. Aircraft often travel in the jet streams to get a speed boost – but when entering or leaving the jet stream, there may be some turbulence as it crosses the boundary with the slower winds outside. <h2>What are the most turbulent routes?</h2> It is possible to <a href="https://turbli.com/maps/world-turbulence-map/">map turbulence patterns</a> over the whole world. Airlines use these maps to plan in advance for alternate airports or other essential contingencies. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/595676/original/file-20240522-21-ippmyt.png?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/595676/original/file-20240522-21-ippmyt.png?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/595676/original/file-20240522-21-ippmyt.png?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=430&fit=crop&dpr=1 600w, https://images.theconversation.com/files/595676/original/file-20240522-21-ippmyt.png?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=430&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/595676/original/file-20240522-21-ippmyt.png?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=430&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/595676/original/file-20240522-21-ippmyt.png?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=541&fit=crop&dpr=1 754w, https://images.theconversation.com/files/595676/original/file-20240522-21-ippmyt.png?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=541&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/595676/original/file-20240522-21-ippmyt.png?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=541&fit=crop&dpr=3 2262w" alt="Map showing air turbulence." /></a><figcaption>A map of estimated clear-air turbulence around the world, current as of 3:00PM AEST (0500 UTC) on May 22 2024. <a class="source" href="https://turbli.com/maps/world-turbulence-map/">Turbli</a></figcaption></figure> While turbulence changes with weather conditions, some regions and routes are more prone to it than others.

Weather radar imagery shows the pilots where the most intense turbulence can be expected, and they work with air traffic control to avoid those areas. When turbulence is encountered unexpectedly, the pilots immediately turn on the “fasten seatbelt” sign and reduce engine thrust to slow down the plane. They will also be in touch with air traffic control to find better conditions either by climbing or descending to smoother air. Ground-based meteorological centres can see weather patterns developing with the assistance of satellites. They provide this information to flight crews in real time, so the crew knows the weather to expect throughout their flight. This can also include areas of expected turbulence if storms develop along the intended flight route. It seems we are heading into more turbulent times. Airlines will do all they can to reduce the impact on planes and passengers. But for the average traveller, the message is simple: when they tell you to fasten your seatbelt, you should listen.<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/230666/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/doug-drury-1277871">Doug Drury</a>, Professor/Head of Aviation, <a href="https://theconversation.com/institutions/cquniversity-australia-2140">CQUniversity Australia</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

When we think about people who have been single for a long time, we may assume it’s because single people have insecurities that make it difficult for them to find a partner or maintain a relationship. But is this true? Or can long-term single people also be secure and thriving? Our <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/jopy.12929">latest research</a> published in the Journal of Personality suggests they can. However, perhaps unsurprisingly, not everybody tends to thrive in singlehood. Our study shows a crucial factor may be a person’s attachment style. <h2>Singlehood is on the rise</h2> Singlehood is on the rise around the world. In Canada, single status among young adults aged 25 to 29 has increased from <a href="https://www150.statcan.gc.ca/n1/daily-quotidien/220713/dq220713b-eng.htm">32% in 1981 to 61% in 2021</a>. The number of people <a href="https://www150.statcan.gc.ca/n1/daily-quotidien/220713/dq220713a-eng.htm">living solo</a> has increased from 1.7 million people in 1981 to 4.4 million in 2021. People are single for many reasons: <a href="https://www.ucpress.edu/ebook/9780520971004/happy-singlehood">some choose</a> to remain single, some are focusing on <a href="https://link.springer.com/article/10.1007/s12147-020-09249-0">personal goals and aspirations</a>, some report <a href="https://www.pewresearch.org/social-trends/2020/08/20/nearly-half-of-u-s-adults-say-dating-has-gotten-harder-for-most-people-in-the-last-10-years/">dating has become harder</a>, and some become single again due to a relationship breakdown. People may also remain single due to their attachment style. Attachment theory is a popular and well-researched model of how we form relationships with other people. An <a href="https://www.amazon.com.au/s?k=attachment+theory">Amazon search for attachment theory</a> returns thousands of titles. The hashtag #attachmenttheory has been viewed <a href="https://www.cnbc.com/2022/08/20/why-attachment-theory-is-trending-according-to-dr-amir-levine.html">over 140 million times</a> on TikTok alone. <h2>What does attachment theory say about relationships?</h2> Attachment theory suggests our relationships with others are shaped by our degree of “anxiety” and “avoidance”. Attachment anxiety is a type of insecurity that leads people to feel anxious about relationships and worry about abandonment. Attachment avoidance leads people to feel uncomfortable with intimacy and closeness. People who are lower in attachment anxiety and avoidance are considered “securely attached”, and are comfortable depending on others, and giving and receiving intimacy. Single people are often stereotyped as being <a href="https://journals.sagepub.com/doi/full/10.1177/01461672231203123">too clingy or non-committal</a>. Research comparing single and coupled people also suggests single people have <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/j.1467-6494.2012.00793.x?casa_token=6iiCm5PjHgkAAAAA:0kBeofx3M-72YrkVppmNxdWBIAImFwm3lAakCnuiNXL20SVP1zaW7UeDIahW_43imAjSRXgtyN0hLVI">higher levels of attachment insecurities</a> compared to people in relationships. At the same time, evidence suggests many single people are choosing to remain single and <a href="https://journals.sagepub.com/doi/full/10.1177/17456916221136119">living happy lives</a>. <h2>Single people represent a diverse group of secure and insecure people</h2> In our latest research, our team of social and clinical psychologists examined single people’s attachment styles and how they related to their happiness and wellbeing. We carried out two studies, one of 482 younger single people and the other of 400 older long-term singles. We found overall 78% were categorised as insecure, with the other 22% being secure. Looking at our results more closely, we found four distinct subgroups of singles: <ul> <li> secure singles are relatively comfortable with intimacy and closeness in relationships (22%) </li> <li> anxious singles question whether they are loved by others and worry about being rejected (37%) </li> <li> avoidant singles are uncomfortable getting close to others and prioritise their independence (23% of younger singles and 11% of older long-term singles) </li> <li> fearful singles have heightened anxiety about abandonment, but are simultaneously uncomfortable with intimacy and closeness (16% of younger singles and 28% of older long-term singles). </li> </ul> <h2>Insecure singles find singlehood challenging, but secure singles are thriving</h2> Our findings also revealed these distinct subgroups of singles have distinct experiences and outcomes. Secure singles are happy being single, have a greater number of non-romantic relationships, and better relationships with family and friends. They meet their sexual needs outside romantic relationships and feel happier with their life overall. Interestingly, this group maintains moderate interest in being in a romantic relationship in the future. Anxious singles tend to be the most worried about being single, have lower self-esteem, feel less supported by close others and have some of the lowest levels of life satisfaction across all sub-groups. Avoidant singles show the least interest in being in a romantic relationship and in many ways appear satisfied with singlehood. However, they also have fewer friends and close relationships, and are generally less satisfied with these relationships than secure singles. Avoidant singles also report less meaning in life and tend to be less happy compared to secure singles. Fearful singles reported more difficulties navigating close relationships than secure singles. For instance, they were less able to regulate their emotions, and were less satisfied with the quality of their close relationships relative to secure singles. They also reported some of the lowest levels of life satisfaction across all sub-groups. <h2>It’s not all doom and gloom</h2> These findings should be considered alongside several relevant points. First, although most singles in our samples were insecure (78%), a sizeable number were secure and thriving (22%). Further, simply being in a romantic relationship is not a panacea. Being in an unhappy relationship is linked to <a href="https://doi.org/10.1371/journal.pmed.1000316">poorer life outcomes</a> than being single. It is also important to remember that attachment orientations are not necessarily fixed. They are open to <a href="https://www.sciencedirect.com/science/article/pii/S2352250X18300113">change</a> in response to life events. Similarly, <a href="https://journals.sagepub.com/doi/full/10.1177/0963721413510933">sensitive and responsive behaviours</a> from close others and <a href="https://doi.org/10.1177/02654075231162390">feeling loved and cared about</a> by close others can soothe underlying attachment concerns and foster attachment security over time. Our studies are some of the first to examine the diversity in attachment styles among single adults. Our findings highlight that many single people are secure and thriving, but also that more work can be done to help insecure single people feel more secure in order to foster happiness.<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/227595/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/christopher-pepping-1524533">Christopher Pepping</a>, Associate Professor in Clinical Psychology, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a>; <a href="https://theconversation.com/profiles/geoff-macdonald-1527971">Geoff Macdonald</a>, Professor of Psychology, <a href="https://theconversation.com/institutions/university-of-toronto-1281">University of Toronto</a>; <a href="https://theconversation.com/profiles/tim-cronin-415060">Tim Cronin</a>, Lecturer in Clinical Psychology, <a href="https://theconversation.com/institutions/la-trobe-university-842">La Trobe University</a>, and <a href="https://theconversation.com/profiles/yuthika-girme-1494822">Yuthika Girme</a>, Associate Professor, Department of Psychology, <a href="https://theconversation.com/institutions/simon-fraser-university-1282">Simon Fraser University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

"We want answers": Furious cruise passengers stage protest after itinerary change

Passengers onboard a Norwegian Cruise Line voyage has expressed their outrage after their once in a lifetime trip to Antarctica changed course after the journey had already begun. Melbourne woman Helen Midler was one of hundreds of people onboard the cruise from Buenos Aires to mainland Antarctica, when staff informed all travellers that their itinerary had changed. Days into their journey, those onboard were told they would not be visiting Antarctica at all, but would be doing a "South America round trip" instead. Midler took to social media to share her frustrations, saying the communication between the cruise line and the passengers was very poor. She explained that she only found out about the change after checking the app a few days into the journey and noticed the name of the cruise had been changed. Passengers were later told the change of destination was for "operational reasons" after raising their concerns, however no further explanation was given. Those onboard were allegedly told the decision was made by the head office in the US to not visit Paradise Bay, on mainland Antarctica, before departure on January 31, and that all passengers were notified by email, and again at check-in. However, Midler claims this was not the case. "I can assure you that we never got any email and many of our friends here on board, and I'm talking hundreds of people we know, did not receive any email either," she said in a video posted online. "Until the cruise had commenced, most people on this ship were not aware of the change in the itinerary." Midler said "everyone was angry", with hundreds of passengers meeting at in the ship's foyer one morning in protest to demand further answers from the crew. "Customer service are refusing to acknowledge us, they sent a security officer out to calm us down," she said while standing in the noisy crowd. "We feel we're being cheated, being scammed". Midler said frustrated travellers, some of whom "spent their live savings" on the cruise that costs upwards of $4,000 per person, just "want answers, transparency and clarity" but claims they're being treated with "absolute disdain and disrespect" with little explanation given. "Everyone on this ship has paid a lot of money to cruise to Antarctica, not to do a round trip of South America at sea," she fumed. "We are being dismissed, ignored, refused answers. They're telling us we just have to accept it. "They think we're idiots. We're not idiots and we're not prepared to just accept this sitting down," she continued. "We may not get to Antarctica. The chances of this cruise now going to Antarctica are minimal. But we want answers." In the days after her initial post, Midler updated her online followers and said those onboard were trying to make the best of a bad situation, despite still not hearing any clear answers about the change of itinerary. "We saved and we booked this two years ago for the trip of a lifetime," she said. "We're feeling very disappointed and dejected about the outcomes here." "We'll never be able to afford to do this again. And we've lost that trip to the Antarctica mainland that we had all been hoping and waiting for, and that we'd paid for. But we're going to try and do our best to enjoy it." Image credits: TikTok

"I want answers": Simon Dorante-Day's cunning plan to prove royal connections

The Queensland man claiming to be the son of King Charles and Queen Camilla has shared his new plan to prove once and for all that he has royal family connections. Simon Dorante-Day has long claimed through his 30 years of research, he discovered that he is the illegitimate son of the monarch, and has attempted to prove his theory through various means. Now, his new plan to get his hands on royal DNA to unequivocally prove his family heritage involves another member of the royal family. Speaking with <a href="https://7news.com.au/lifestyle/aussie-man-claiming-to-be-charles-son-drops-new-prince-harry-dna-bombshell-c-13488374" target="_blank" rel="noopener">7News</a>, the 57-year-old said he and his wife have been told by a “trusted source” that Prince Harry could be amenable to helping them gather proof. “We got advice from a really good, really trusted source that we should approach Harry and make a connection there and ask for DNA,” Elvianna said. Simon added, “I was really taken aback when he said that. But it’s definitely something I’m going to do. I’ve long been a supporter of Harry and Meghan, I think it’s disgraceful the way they’ve been treated by the royal family." “The way they are treated on social media too, it’s just one big ‘Punch-Meghan-and-Harry-a-thon’, seriously. It’s really starting to annoy me." He said he is planning to "make contact with him and explore this as an opportunity," pointing out that the royal family's treatment of Harry could make him more willing to help. "At the end of the day, I feel like he just might be as keen as I am to expose what Charles and Camilla and the powers that be have done to me. The injustice." “It’s worth me pointing out that Charles and Camilla, Buckingham Palace, the entire royal family - not one of them has ever said my claims are not true. They’ve never denied what I believe, told me I’m wrong." Simon said “the wheels are in motion” in terms of making contact with Prince Harry, and that he’s hopeful of a positive outcome. “I want answers,” he said. “And I feel Prince Harry is the man to help me find them.” “And I think their silence speaks volumes.” Simon said “the wheels are in motion” in terms of making contact with Prince Harry, and that he’s hopeful of a positive outcome. “I want answers,” he said. “And I feel Prince Harry is the man to help me find them.” Image credits: Facebook / Getty Images

It’s time to limit how often we can travel abroad – ‘carbon passports’ may be the answer

<a href="https://theconversation.com/profiles/ross-bennett-cook-1301368">Ross Bennett-Cook</a>, <a href="https://theconversation.com/institutions/university-of-westminster-916">University of Westminster</a> The summer of 2023 has been very significant for the travel industry. By the end of July, international tourist arrivals globally <a href="https://www.unwto.org/news/international-tourism-swiftly-overcoming-pandemic-downturn">reached 84% of pre-pandemic levels</a>. In <a href="https://joint-research-centre.ec.europa.eu/jrc-news-and-updates/eu-tourism-almost-full-recovery-pre-pandemic-levels-2023-10-23_en">some European countries</a>, such as France, Denmark and Ireland, tourism demand even surpassed its pre-pandemic level. This may be great <a href="https://skift.com/insight/state-of-travel/">news economically</a>, but there’s concern that a return to the status quo is already showing dire environmental and social consequences. The summer saw record-breaking heatwaves across many parts of the world. People were forced to flee <a href="https://www.theguardian.com/world/2023/jul/24/greece-wildfires-corfu-evia-rhodes-heatwave-northern-hemisphere-extreme-weather-temperatures-europe">wildfires in Greece</a> and <a href="https://www.independent.co.uk/climate-change/news/hawaii-fires-update-biden-b2393188.html">Hawaii</a>, and extreme <a href="https://www.manchestereveningnews.co.uk/news/world-news/foreign-office-issues-spain-weather-27339111">weather warnings</a> were issued in many popular holiday destinations like Portugal, Spain and Turkey. Experts <a href="https://theconversation.com/european-heatwave-whats-causing-it-and-is-climate-change-to-blame-209653">attributed these extreme conditions</a> to climate change. Tourism is part of the problem. The tourism sector <a href="https://wttc.org/Portals/0/Documents/Reports/2021/WTTC_Net_Zero_Roadmap.pdf">generates around one-tenth</a> of the greenhouse gas emissions that are driving the climate crisis. The negative impacts of tourism on the environment have become so severe that some are suggesting drastic changes to our travel habits are inevitable. In a <a href="https://www.intrepidtravel.com/sites/intrepid/files/basic_page/files/A%20Sustainable%20Future%20For%20Travel%20From%20Crisis%20To%20Transformation-231016-02.pdf">report</a> from 2023 that analysed the future of sustainable travel, tour operator Intrepid Travel proposed that “carbon passports” will soon become a reality if the tourism industry hopes to survive. <h2>What is a carbon passport?</h2> The idea of a carbon passport centres on each traveller being assigned a yearly carbon allowance that they cannot exceed. These allowances can then “ration” travel. This concept may seem extreme. But the idea of personal carbon allowances is not new. A <a href="https://publications.parliament.uk/pa/cm200708/cmselect/cmenvaud/565/565.pdf">similar concept</a> (called “personal carbon trading”) was discussed in the House of Commons in 2008, before being shut down due to its perceived complexity and the possibility of public resistance. The <a href="https://www.nature.org/en-us/get-involved/how-to-help/carbon-footprint-calculator/#:%7E:text=A%20carbon%20footprint%20is%20the,is%20closer%20to%204%20tons.">average annual carbon footprint</a> for a person in the US is 16 tonnes – one of the highest rates in the world. In the UK this figure sits at 11.7 tonnes, still more than five times the figure recommended by the <a href="https://www.openaccessgovernment.org/the-average-british-carbon-footprint-is-five-times-over-paris-agreement-recommendations/152669/#:%7E:text=Despite%20rising%20environmental%20awareness%20across,equivalent%20(tCO2e)%20per%20year.">Paris Agreement</a> to keep global temperature rise below 1.5°C. Globally, the average annual carbon footprint of a person is closer to 4 tonnes. But, to have the best chance of preventing temperature rise from overshooting 2°C, the average global carbon footprint <a href="https://www.nature.org/en-us/get-involved/how-to-help/carbon-footprint-calculator/#:%7E:text=Globally%2C%20the%20average%20carbon%20footprint,tons%20doesn't%20happen%20overnight!">needs to drop</a> to under 2 tonnes by 2050. This figure equates to around <a href="https://www.theguardian.com/environment/ng-interactive/2019/jul/19/carbon-calculator-how-taking-one-flight-emits-as-much-as-many-people-do-in-a-year">two return flights</a> between London and New York. Intrepid Travel’s report predicts that we will see carbon passports in action by 2040. However, <a href="https://www.politico.eu/article/travel-short-haul-flights-europe-under-fire-climate-change-cop26/">several laws and restrictions</a> have been put in place over the past year that suggest our travel habits may already be on the verge of change. <h2>Targeting air travel</h2> Between 2013 and 2018, the amount of CO₂ emitted by commercial aircrafts worldwide <a href="https://theicct.org/sites/default/files/publications/ICCT_CO2-commercl-aviation-2018_20190918.pdf">increased by 32%</a>. Improvements in fuel efficiency are slowly reducing per passenger emissions. But <a href="https://www.sciencedirect.com/science/article/pii/S1352231014004889">research</a> from 2014 found that whatever the industry’s efforts to reduce its carbon emissions, they will be outweighed by the growth in air traffic. For emission reductions to have any meaningful effect, ticket prices would have to rise by 1.4% each year, discouraging some people from flying. However, in reality, <a href="https://www.climatecentral.org/news/increase-in-flights-will-outweigh-carbon-cuts-17875">ticket prices are falling</a>. Some European countries are beginning to take measures to reduce air travel. As of April 1 2023, passengers on short-haul flights and older aircraft in Belgium have been <a href="https://www.euronews.com/green/2022/12/12/private-jets-and-short-haul-flights-face-pollution-busting-tax-increases-in-belgium">subject to increased taxes</a> to encourage alternative forms of travel. Less than two months later France banned <a href="https://www.bbc.co.uk/news/world-europe-65687665">short-haul domestic flights</a> where the same trip can be made by train in two-and-a-half hours or less. <a href="https://businesstravelerusa.com/news/spain-to-follow-frances-lead-plans-to-ban-short-haul-domestic-flights/">Spain</a> is expected to follow suit. A similar scheme could also be on the horizon for Germany. In 2021, a <a href="https://www.cleanenergywire.org/news/seventy-percent-germans-favour-banning-short-haul-flights-survey">YouGov poll</a> found that 70% of Germans would support such measures to fight climate change if alternative transport routes like trains or ships were available. <h2>Cruises and carbon</h2> It’s not just air travel that’s being criticised. An <a href="https://www.transportenvironment.org/wp-content/uploads/2023/06/The-return-of-the-cruise-June-2023.pdf">investigation</a> by the European Federation for Transport and Environment in 2023 found that cruise ships pump four times as many sulphuric gases (which are proven to cause acid rain and <a href="https://www.forbes.com/sites/jamesellsmoor/2019/04/26/cruise-ship-pollution-is-causing-serious-health-and-environmental-problems/?sh=468ee2f637db">several respiratory conditions</a>) into the atmosphere than all of Europe’s 291 million cars combined. Statistics like these have forced European destinations to <a href="https://www.ft.com/content/8727387d-590d-43bd-a305-b5ec208a4dfe">take action</a> against the cruise industry. In July, Amsterdam’s council <a href="https://www.bbc.co.uk/news/world-europe-66264226">banned cruise ships</a> from docking in the city centre in a bid to reduce tourism and pollution – an initiative that has shown success elsewhere. In 2019 Venice was the most polluted European port, due to large numbers of cruise ship visits. But it dropped to 41st place in 2022 after a ban on large cruise ships entering the city’s waters <a href="https://www.transportenvironment.org/discover/europes-luxury-cruise-ships-emit-as-much-toxic-sulphur-as-1bn-cars-study/">reduced air pollutants from ships</a> in Venice by 80%. <h2>Changing destinations</h2> Intrepid Travel’s report also highlights that not only how we travel, but <a href="https://joint-research-centre.ec.europa.eu/jrc-news-and-updates/global-warming-reshuffle-europes-tourism-demand-particularly-coastal-areas-2023-07-28_en">where we travel</a> will soon be impacted by climate change. Boiling temperatures will probably diminish the allure of traditional beach destinations, prompting European tourists to search for cooler destinations such as Belgium, Slovenia and Poland for their summer holidays. <a href="https://www.travelweekly.com/Travel-News/Tour-Operators/Travelers-seek-cooler-destinations-this-summer">Several travel agencies</a> reported seeing noticeable increases in holiday bookings to cooler European destinations like Scandinavia, Ireland and the UK during 2023’s peak summer travel months. Whatever the solution may be, changes to our travel habits look inevitable. Destinations across the globe, from <a href="https://www.theneweuropean.co.uk/barcelonas-war-on-tourism-ada-colau/">Barcelona</a> to the <a href="https://www.dw.com/en/italy-tourism-bans-controls-fees-restrictions/a-66453047">Italian riveria</a> and even <a href="https://theconversation.com/death-on-everest-the-boom-in-climbing-tourism-is-dangerous-and-unsustainable-114033">Mount Everest</a> are already calling for limits on tourist numbers as they struggle to cope with crowds and pollution.

Should we still be using RATs to test for COVID? 4 key questions answered

<a href="https://theconversation.com/profiles/hassan-vally-202904">Hassan Vally</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> We’re currently navigating <a href="https://www.thenewdaily.com.au/life/health/2023/11/15/covid-australia-eighth-wave">an eighth wave</a> of <a href="https://theconversation.com/were-in-a-new-covid-wave-what-can-we-expect-this-time-216820">COVID infections</a> in Australia. However the threat COVID poses to us is significantly less than it has ever been, thanks to immunity we’ve acquired through <a href="https://www.thelancet.com/journals/laninf/article/PIIS1473-3099(22)00801-5/fulltext">a combination</a> of prior infection and vaccination. That said, COVID is by no means behind us. The threat of severe illness remains higher for many people, and we’re all potentially at risk of developing <a href="https://www.health.gov.au/topics/covid-19/long-covid">long COVID</a>. While many people appear to be doing fewer rapid antigen tests (RATs) than they used to – if any at all – with rising cases, and as we head towards the festive season, testing continues to be important. So what do you need to know about testing in this wave? Here are four key questions answered. <h2>1. When should I do a RAT?</h2> There are a few situations where determining your COVID status is important to inform your actions, particularly during an uptick in infections. With more circulating virus, your index of suspicion that you have COVID if you’re experiencing cold-like symptoms should be higher. RATs work best when they’re used to confirm whether you have COVID when you <a href="https://www.tga.gov.au/products/covid-19/covid-19-tests/how-testing-works-covid-19">have respiratory symptoms</a> and are infectious. So the primary use of RATs should be to determine your COVID status when you’re sick. A positive test should prompt you to isolate, and if you’re eligible, to seek antivirals. Testing might also be worthwhile if you’ve come into contact with someone with COVID but you haven’t developed symptoms. If you find you have in fact contracted the virus, you can take steps to avoid spreading it to other people (you can infect others even <a href="https://www.healthline.com/health/what-is-asymptomatic-covid#prevalence">when you’re asymptomatic</a>). This is especially important if you’re going to be socialising in large groups or in contact with people who are vulnerable. Another situation in which to consider testing, particularly at this time of year, is before attending large social gatherings. While the reliability of a RAT is never perfect, do the test as close to the event as possible, because your disease status <a href="https://www.businessinsider.com/omicron-rapid-test-hour-before-party-not-day-before-expert-2021-12">can change quickly</a>. <h2>2. Should I test multiple times?</h2> Yes. RATs are not as sensitive as PCR tests, which is the trade-off we make for being able to do this test at home and <a href="https://www.wsj.com/articles/public-health-officials-pursue-covid-19-tests-that-trade-precision-for-speed-11599562800">getting a rapid result</a>. This means that while if you test positive with a RAT you can be very confident you have COVID, if you test negative, you cannot be as confident that you don’t have COVID. That is, the test may give you a false negative result. Although RATs from different manufacturers have different accuracies, all RATs approved by Australia’s Therapeutic Goods Administration must have a sensitivity of <a href="https://www.tga.gov.au/products/covid-19/covid-19-tests/covid-19-rapid-antigen-self-tests-home-use/covid-19-rapid-antigen-self-tests-are-approved-australia#:%7E:text=For%20rapid%20antigen%20tests%2C%20this,specificity%20of%20at%20least%2098%25.">at least 80%</a>. The way to increase your confidence in a negative result is to do multiple RATs serially – each negative test increases the confidence you can have that you don’t have COVID. If you have symptoms and have tested negative after your first RAT, <a href="https://www.fda.gov/medical-devices/safety-communications/home-covid-19-antigen-tests-take-steps-reduce-your-risk-false-negative-results-fda-safety">the advice</a> is to repeat the test after 48 hours, and potentially a third time after another 48 hours if the second test is also negative. <h2>3. Do RATs detect the latest variants?</h2> Since RATs <a href="https://www.healthdirect.gov.au/covid-19/testing#:%7E:text=Rapid%20antigen%20tests%2C%20or%20RATs,of%20proteins%20of%20the%20virus.">detect particular surface proteins</a> on SARS-CoV-2 (the virus that causes COVID), it’s theoretically possible that as the virus evolves, the reliability of these tests may be affected. However, RATs were designed to detect a part of the virus that is not as likely to mutate, so the hope is these tests <a href="https://www.health.com/do-covid-tests-work-new-variants-7967102">will continue to hold up</a> as SARS-CoV-2 evolves. The performance of RATs is continually being assessed by manufacturers. So far, there’s been no change reported in the ability of these tests to <a href="https://www.ama.com.au/articles/tga-updated-advice-rats-nearing-expiry-and-rats-efficacy-current-strains#:%7E:text=The%20TGA%20has%20received%20evidence,19%20RAT%20post%2Dmarket%20review.">detect the latest variants</a>. <h2>4. Can I rely on expired RATs?</h2> At this point in the pandemic, you might have a few expired tests at the back of your cupboard. Technically the most appropriate advice is to say you should never use a diagnostic test <a href="https://www.tga.gov.au/products/covid-19/covid-19-tests/covid-19-rapid-antigen-self-tests-home-use/covid-19-rapid-antigen-self-tests-are-approved-australia">past its expiry date</a>. As a general principle the performance of a test cannot be guaranteed beyond this date. The risk is that over time the components of the RAT degrade and if you use a test that’s not working optimally, it’s more likely to indicate <a href="https://www.health.com/can-you-use-expired-covid-test-6827970">you don’t have COVID</a> when you actually do, which may have consequences. However, as for all things COVID, the answer is not so black and white. Since these tests were new when they were introduced earlier in the pandemic, manufacturers didn’t have specific data on their performance over time, and so the expiry dates given were necessarily conservative. It’s likely these tests will work beyond the expiry dates on the packet, but just how long and how well they work is a bit of an unknown, so we need to be cautious. The other thing to consider is ensuring you store RATs correctly. Storage instructions should be found on the packet, but the key issue is making sure they’re not exposed to extreme temperatures. In particular, <a href="https://7news.com.au/lifestyle/health-wellbeing/how-to-properly-store-your-at-home-covid-19-rapid-antigen-tests-c-5465412">high temperatures</a> may damage the chemicals in the test which may reduce its sensitivity. <h2>The path from here</h2> Regular upticks in COVID cases are something we’re going to have to get used to. At these times, we should all be a bit more cautious about looking after ourselves and others as we go about our lives. What this looks like will vary for different people depending on their personal circumstances. However, being up to date with <a href="https://theconversation.com/what-are-the-new-covid-booster-vaccines-can-i-get-one-do-they-work-are-they-safe-217804">booster vaccinations</a>, having a plan for <a href="https://www.health.gov.au/topics/covid-19/oral-treatments">accessing antivirals</a> if you’re eligible, <a href="https://theconversation.com/with-covid-surging-should-i-wear-a-mask-217902">wearing masks</a> in high-risk settings and testing all continue to play an important role in responding to COVID.<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/218016/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/hassan-vally-202904">Hassan Vally</a>, Associate Professor, Epidemiology, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Research reveals who’s been hit hardest by global warming in their lifetime - and the answer may surprise you

<a href="https://theconversation.com/profiles/andrew-king-103126">Andrew King</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a>; <a href="https://theconversation.com/profiles/ed-hawkins-104793">Ed Hawkins</a>, <a href="https://theconversation.com/institutions/university-of-reading-902">University of Reading</a>; <a href="https://theconversation.com/profiles/hunter-douglas-1460792">Hunter Douglas</a>, <a href="https://theconversation.com/institutions/te-herenga-waka-victoria-university-of-wellington-1200">Te Herenga Waka — Victoria University of Wellington</a>, and <a href="https://theconversation.com/profiles/luke-harrington-489028">Luke Harrington</a>, <a href="https://theconversation.com/institutions/university-of-waikato-781">University of Waikato</a> Earth is warming and the signs of climate change are everywhere. We’ve seen it in the past few weeks as temperatures hit record highs around the world – both in the Northern Hemisphere and the <a href="https://theconversation.com/why-is-australia-having-such-a-warm-winter-a-climate-expert-explains-210693">warm Australian winter</a>. Global warming is caused by humanity’s greenhouse gas emissions, which continue at <a href="https://theconversation.com/global-carbon-emissions-at-record-levels-with-no-signs-of-shrinking-new-data-shows-humanity-has-a-monumental-task-ahead-193108">near-record pace</a>. These emissions are predominantly generated by people in the world’s wealthiest regions. Our world-first analysis, <a href="https://iopscience.iop.org/article/10.1088/2752-5295/aceff2">published today</a>, examines the experience of global warming over the lifetimes of people around the world: young and old, rich and poor. We sought to identify who has perceived warmer temperatures most keenly. We found middle-aged people in equatorial regions have lived through the most perceptible warming in their lifetimes. But many young people in lower-income countries could experience unrecognisable changes in their local climate later in life, unless the world rapidly tackles climate change. <h2>Measuring the climate change experience</h2> We examined temperature data and population demographics information from around the world. Key to our analysis was the fact that not all warming is due to human activity. Some of it is caused by natural, year-to-year variations in Earth’s climate. These natural ups and downs are due to a number of factors. They include variations in the energy Earth receives from the sun, the effects of volcanic eruptions, and transfers of heat between the atmosphere and the ocean. This variability is stronger in mid-to-high-latitude parts of the world (those further from the equator) than in low-latitude areas (in equatorial regions). That’s because the weather systems further away from the equator draw in hot or cold air from neighbouring areas, but equatorial areas don’t receive cold air at all. That’s why, for example, the annual average temperature in New York is naturally more variable than in the city of Kinshasa (in the Democratic Republic of Congo). To account for this, we applied what’s known as the “<a href="https://archive.ipcc.ch/ipccreports/tar/wg1/346.htm#:%7E:text=The%20%EF%BF%BDsignal%20to%20noise,to%20this%20natural%20variability%20noise.">signal-to-noise ratio</a>” at each location we studied. That allowed us to separate the strength of the climate change “signal” from the “noise” of natural variability. Making this distinction is important. The less naturally variable the temperature, the clearer the effects of warming. So warming in Kinshasa over the past 50 years has been much more perceptible than in New York. Our study examined two central questions. First, we wanted to know, for every location in the world, how clearly global warming could be perceived, relative to natural temperature variability. Second, we wanted to know where this perceived change was most clear over human lifetimes. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/541474/original/file-20230807-17-ogjdti.png?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/541474/original/file-20230807-17-ogjdti.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/541474/original/file-20230807-17-ogjdti.png?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=394&fit=crop&dpr=1 600w, https://images.theconversation.com/files/541474/original/file-20230807-17-ogjdti.png?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=394&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/541474/original/file-20230807-17-ogjdti.png?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=394&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/541474/original/file-20230807-17-ogjdti.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=495&fit=crop&dpr=1 754w, https://images.theconversation.com/files/541474/original/file-20230807-17-ogjdti.png?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=495&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/541474/original/file-20230807-17-ogjdti.png?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=495&fit=crop&dpr=3 2262w" alt="Annual-average temperatures at four major cities with signal-to-noise ratios shown for 20, 50 and 80 years up to 2021." /></a><figcaption>Annual-average temperatures at four major cities with signal-to-noise ratios shown for 20, 50 and 80 years up to 2021. Author provided</figcaption></figure> <h2>Our results</h2> So what did we find? As expected, the most perceptible warming is found in tropical regions – those near the equator. This includes developing parts of the world that constitute the Global South – such as Africa, Latin America and the Caribbean, and Asia. Household incomes in the Global South are typically lower than in industrialised nations (known as the Global North). We might, then, conclude people in the poorest parts of the world have experienced the most perceptible global warming over their lifetimes. But that’s not always the case. Why? Because most parts of the Global South have younger populations than wealthier regions. And some people under the age of 20, including in northern India and parts of Sub-Saharan Africa, haven’t experienced warming over their lifetimes. In these places, the lack of recent warming is likely down to a few factors: natural climate variability, and the local cooling effect of particles released into the atmosphere from <a href="https://iopscience.iop.org/article/10.1088/1748-9326/ac3b7a">pollution</a> and changes in land use. There’s another complication. Some populated regions of the world also experienced slight cooling in the mid-20th century, primarily driven by human-caused <a href="https://www.nature.com/articles/nature10946">aerosol emissions</a>. So, many people born earlier than the 1950s have experienced less perceptible warming in their local area than those born in the 1960s and 1970s. This may seem counter-intuitive. But a cooling trend in the first few decades of one’s life means the warming experienced over an entire lifespan (from birth until today) is smaller and less detectable. So what does all this mean? People in equatorial areas born in the 1960s and 1970s – now aged between about 45 and 65 – have experienced more perceptible warming than anyone else on Earth. <h2>Rich countries must act</h2> Our findings are important, for several reasons. Identifying who has experienced significant global warming in their lives may help explain <a href="https://www.nature.com/articles/nclimate2660">attitudes to tackling climate change</a>. Our findings also raise significant issues of fairness and equity. Humanity will continue to warm the planet until we reach global net-zero emissions. This means many young people in lower-income countries may, later in life, experience a local climate that is unrecognisable to that of their youth. Of course, warming temperatures are not the only way people experience climate change. Others include sea-level rise, more intense drought and rainfall extremes. We know many of these impacts are felt most acutely by <a href="https://www.aljazeera.com/opinions/2022/5/11/climate-change-is-devastating-the-global-south">the most vulnerable populations</a>. Cumulative greenhouse gas emissions are much higher in the Global North, due to economic development. To address this inequality, rich industrialised nations must take a leading role in reducing emissions to net-zero, and helping vulnerable countries adapt to climate change.<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/211108/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/andrew-king-103126">Andrew King</a>, Senior Lecturer in Climate Science, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a>; <a href="https://theconversation.com/profiles/ed-hawkins-104793">Ed Hawkins</a>, Professor of Climate Science, <a href="https://theconversation.com/institutions/university-of-reading-902">University of Reading</a>; <a href="https://theconversation.com/profiles/hunter-douglas-1460792">Hunter Douglas</a>, PhD Candidate, <a href="https://theconversation.com/institutions/te-herenga-waka-victoria-university-of-wellington-1200">Te Herenga Waka — Victoria University of Wellington</a>, and <a href="https://theconversation.com/profiles/luke-harrington-489028">Luke Harrington</a>, Senior Lecturer in Climate Change, <a href="https://theconversation.com/institutions/university-of-waikato-781">University of Waikato</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Travel Trouble

Flight attendants answer frequently asked flying questions

A flight attendant has shared the answers to a series of every traveller’s burning questions about air travel. In a video shared to TikTok, Virgin Australia crew member Brodie Capron answered commonly asked questions about why carry-on bags have a weight limit and why the window shades have such strict limits. According to Capron, the reasoning behind why carry-on bags can only weigh so much is pretty simple. "That's because the overhead lockers can only hold so much weight," she said. The Melbourne-based cabin crew member also explained why the window shades need to be up for take off and landing, and it has nothing to do with helping your eyes adjust. "It's so that everyone can see the engines and warn the cabin crew if something is wrong," she said. Capron also debunked a common plane myth, ensuring nervous passengers that the water on planes is indeed “safe to drink”. "It is filtered and it is clean," she said. For those who like to enjoy a drink or two while travelling, Capron did confirm that you can in fact get 'more' drunk when flying. "[It's] because of the lower oxygen percentage in the air, the effects of alcohol are greater," she said. "So make sure you make good choices when you're flying." Her video has received over half a million views with many people thanking her for finally answering their burning questions about flying. Image credits: Shutterstock

“We need answers”: Parents of man shot by police speak out

The parents of a man who was shot and killed by a police officer on a Queensland beach have spoken about how they were told the heartbreaking news. Luke Gilbert was with his girlfriend at Airlie Beach, Townsville, when he allegedly approached police with a pen knife in the early hours on the morning of Saturday, October 1. The 24-year-old allegedly continued advancing towards the patrolling officers when he was shot five times. After police rendered first aid to him, Luke was transported to Proseperine Hospital but died a short time later. <blockquote class="twitter-tweet"> AIRLIE BEACH: A man aged in his 20’s and allegedly armed with a knife was fatally shot by police in Airlie Beach this morning (October 1) <a href="https://t.co/cBz4wyfM3u">https://t.co/cBz4wyfM3u</a> <a href="https://t.co/mGcTxtosUo">pic.twitter.com/mGcTxtosUo</a> — Queensland Police (@QldPolice) <a href="https://twitter.com/QldPolice/status/1575945897787109377?ref_src=twsrc%5Etfw">September 30, 2022</a></blockquote> His parents, Nicola and Darren Gilbert, told 9News of the tragic moment when police informed them that their son had died. “Two police officers came in and they just stood, they didn’t even ask us to sit down, and they just stood at the kitchen bench and just said, ‘We’ve very sorry to tell you but your son has died’,” Ms Gilbert said. Luke, who grew up in Western Australia, was working in Townsville at the time of the incident. Mr Gilbert has called for an explanation for why his son was shot, describing it as a “massive failing” of police. “What happened? We need answers,” he said. “This is a massive failing of the Queensland Police.” According to the police union, officers had no choice but to shoot Luke after he allegedly “lunged” at them with the knife. The officers fired four or five shots at Luke after he continued to approach them despite them drawing their weapons and telling him to stop. Ian Leavers, the President and CEO of the Queensland Police Union, said Luke had “all of a sudden produced a knife from his hoodie and started threatening police”. “The police have tried to further engage and they have retreated and moved from that location and tried and continue to communicate with that male person,” he told reporters. “At a point, (he) has lunged at police and they’ve had no other alternative but to use their firearm. “Police did all they could to try and resolve this matter peacefully.” As police swarmed the popular tourist spot on Saturday to determine the circumstances surrounding the shooting, Superintendent Graeme Paine said officers were speaking to several witnesses and that the incident was captured on CCTV. Several people in the area at the time also captured the shooting on video. In one clip, shots can be heard in the background and a man says, “They just f***ing shot him. “I thought they were gonna get him with a taser. “They just f***ing shot him c***s. He just kept walking to the cops.” In the wake of the news, the 24-year-old’s brother Zac shared an emotional tribute on Facebook. “I don’t know how to say this It’s not even sinking in yet and it doesn’t seem real,” he wrote. “Life will never be the same, he deserved a lot better than this! I can’t believe this has happened, he's at rest now.” Luke’s brother claimed that police used “excess force” after the 24-year-old pulled out a knife “for reasons unknown right now”. “For all those who don't know this, my brother was on a night out with his girlfriend and as far as we know luke walked up to two police officers, they were talking and then for reasons unknown right now, luke pulled out a pen knife (4cm) and in reaction to that the officers shot 4 to 5 times at my brother and 1 of them being fatal,” Zac wrote. “There’s a lot of speculation in the media about the circumstances surrounding the loss of my brother but just know the truth is excess force was used on him which killed him and that can never be undone, they didn’t try the taser, the baton or the pepper spray first they went straight for the guns carelessly.” The incident is being investigated by the Ethical Standards Committee on behalf of the state coroner.

Does a sibling’s gender influence our own personality? A major new study answers an age-old question

Our siblings play a central role in our childhoods, so it stands to reason they influence our personality in the long term. In particular, researchers have long been interested in how growing up with a sister compared to a brother might influence who we become as adults. How do children interact with their sister or brother? How do parents behave differently towards their children of different genders, and how does that interaction influence the children? Past theories have made quite different predictions: siblings of the opposite gender may plausibly result in either <a href="https://doi.org/10.2307/2786054" target="_blank" rel="noopener">gender-stereotypical personalities</a> (a girl may take on a more feminine role to differentiate herself from her brother) or <a href="https://doi.org/10.9783/9781512800807" target="_blank" rel="noopener">less gender stereotypical personalities</a> (a girl may take on more masculine traits because she imitates her brother). In fact, psychological research has been exploring these differences for over half a century. <a href="https://doi.org/10.1016/j.paid.2015.02.037" target="_blank" rel="noopener">In some studies</a>, siblings of the opposite sex seemed to be more gender-conforming. Girls with brothers later become more “typically female” and boys with sisters more “typically male”. <a href="https://doi.org/10.1037/h0030055" target="_blank" rel="noopener">Other studies find the exact opposite</a>, however. Opposite gender siblings developed in typically gender-conforming ways. To resolve these contradictions, we wanted to test the effect of sibling gender on personality in a rigorous and comprehensive way. <figure class="align-center "><img src="https://images.theconversation.com/files/480681/original/file-20220823-16-4ll79p.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/480681/original/file-20220823-16-4ll79p.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=400&fit=crop&dpr=1 600w, https://images.theconversation.com/files/480681/original/file-20220823-16-4ll79p.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=400&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/480681/original/file-20220823-16-4ll79p.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=400&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/480681/original/file-20220823-16-4ll79p.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=503&fit=crop&dpr=1 754w, https://images.theconversation.com/files/480681/original/file-20220823-16-4ll79p.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=503&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/480681/original/file-20220823-16-4ll79p.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=503&fit=crop&dpr=3 2262w" alt="" /><figcaption>Like brother, like sister? Researchers have differed on the likely influence of an opposite gender sibling on personality. Getty Images</figcaption></figure> Using big data In our <a href="https://doi.org/10.1177/09567976221094630" target="_blank" rel="noopener">new study</a> we focused on the relationships between children and their next older or younger sibling. We compiled a unique data set by combining 12 large representative surveys covering nine countries across four continents (US, UK, Netherlands, Germany, Switzerland, Australia, Mexico, China and Indonesia). This resulted in a data set of more than 85,000 people – many times the sample sizes used in previous studies. We also investigated many more personality traits than previous studies have. This included the traits that have been most widely studied in other research, and which have been shown to be important predictors of people’s decisions and choices. The “big five” of these traits are: openness to experiences, conscientiousness, extroversion, agreeableness and neuroticism. The other traits examined were: risk tolerance, trust, patience and “locus of control” (the degree to which people believe they have control over their lives). We also created an index describing to what extent people have a typically female personality. This allowed us to test comprehensively whether growing up with an opposite gender sibling leads to a more or less gender-stereotypical personality. Sibling gender and life experience This study is not only innovative in its use of a large data set, but it also applies a consistent method to identify any causal effects of a sibling’s gender on personality traits. To estimate credible causal effects, we make use of an interesting fact of nature: once parents decide to have another child it is essentially random whether they have a girl or boy. In this “natural experiment” some people are therefore “randomly assigned” a younger sister or brother. This allows us to estimate the causal effect of sibling gender on personality by comparing the average personality of people who grew up with a sister as their next youngest sibling with those who grew up with a next younger brother. Brothers and sisters Our results suggest sibling gender has no effect on personality. For all nine personality traits and the summary index, we find people who have a next younger sister display, on average, the same personality traits as people who have a next younger brother. We also see no difference in personality between people who have a next older sister and people who have a next older brother. Because we have data on more than 85,000 people, these results are estimated with great precision. The results help refute the idea that brothers or sisters cause each other to develop “feminine” or “masculine” personality traits over the long term. However, the results don’t mean sibling gender has no long-term effect at all. Other studies that applied a similar methodological approach have shown that women with brothers in the <a href="https://doi.org/10.1016/j.labeco.2019.02.009" target="_blank" rel="noopener">US</a> and <a href="https://doi.org/10.1007/s00148-021-00830-9" target="_blank" rel="noopener">Denmark</a> earn less. And a <a href="https://doi.org/10.1093/qje/qjt011" target="_blank" rel="noopener">study of Asian populations</a> has found women with younger sisters marry earlier and women with older sisters marry later. So, there seem to be interesting sibling dynamics related to gender – but personality is probably not part of the explanation for those effects.<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/188532/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/jan-feld-594140" target="_blank" rel="noopener">Jan Feld</a>, Senior Lecturer in Economics, <a href="https://theconversation.com/institutions/te-herenga-waka-victoria-university-of-wellington-1200" target="_blank" rel="noopener">Te Herenga Waka — Victoria University of Wellington</a>; <a href="https://theconversation.com/profiles/anne-ardila-brenoe-1373305" target="_blank" rel="noopener">Anne Ardila Brenøe</a>, Assistant Professor of Economics, <a href="https://theconversation.com/institutions/university-of-zurich-1139" target="_blank" rel="noopener">University of Zurich</a>, and <a href="https://theconversation.com/profiles/thomas-dudek-1372681" target="_blank" rel="noopener">Thomas Dudek</a>, Postdoctoral Researcher, <a href="https://theconversation.com/institutions/te-herenga-waka-victoria-university-of-wellington-1200" target="_blank" rel="noopener">Te Herenga Waka — Victoria University of Wellington</a> This article is republished from <a href="https://theconversation.com" target="_blank" rel="noopener">The Conversation</a> under a Creative Commons license.

Which of these pictures is a deepfake? Your brain knows the answer before you do

Deepfakes – AI-generated videos and pictures of people – are becoming more and more realistic. This makes them the perfect weapon for disinformation and fraud. But while you might consciously be tricked by a deepfake, new evidence suggests that your brain knows better. Fake portraits cause different signals to fire on brain scans, according to a paper <a href="https://doi.org/10.1016/j.visres.2022.108079" target="_blank" rel="noreferrer noopener">published</a> in Vision Research. While you consciously can’t spot the fake (for those playing at home, the face on the right is the phony), your neurons are more reliable. “Your brain sees the difference between the two images. You just can’t see it yet,” says co-author Associate Professor Thomas Carlson, a researcher at the University of Sydney’s School of Psychology. The researchers asked volunteers to view a series of several hundred photos, some of which were real and some of which were fakes generated by a GAN (a Generative Adversarial Network, a common way of making deepfakes). One group of 200 participants was asked to guess which images were real, and which were fake, by pressing a button. A different group of 22 participants didn’t guess, but underwent electroencephalography (EEG) tests while they were viewing the images. The EEGs showed distinct signals when participants were viewing deepfakes, compared to real images. “The brain is responding different than when it sees a real image,” says Carlson. <div class="newsletter-box"> <div id="wpcf7-f6-p197814-o1" class="wpcf7" dir="ltr" lang="en-US" role="form"> <form class="wpcf7-form mailchimp-ext-0.5.62 spai-bg-prepared init" action="/technology/deepfakes-brain-eegs/#wpcf7-f6-p197814-o1" method="post" novalidate="novalidate" data-status="init"> <input class="wpcf7-form-control wpcf7-text referer-page spai-bg-prepared" name="referer-page" type="hidden" value="https://cosmosmagazine.com/technology/" data-value="https://cosmosmagazine.com/technology/" aria-invalid="false" /> </form> </div> </div> “It’s sort of difficult to figure out what exactly it’s picking up on, because all you can really see is that it is different – that’s something we’ll have to do more research to figure out.” The EEG scans weren’t foolproof: they could only spot deepfakes 54% of the time. But that’s significantly better than the participants who were guessing consciously. People only found deepfakes 37% of the time – worse than if they’d just flipped a coin. “The fact that the brain can detect deepfakes means current deepfakes are flawed,” says Carlson. “If we can learn how the brain spots deepfakes, we could use this information to create algorithms to flag potential deepfakes on digital platforms like Facebook and Twitter.” It could also be used to prevent fraud and theft. “EEG-enabled helmets could have been helpful in preventing recent bank heist and corporate fraud cases in Dubai and the UK, where scammers used cloned voice technology to steal tens of millions of dollars,” says Carlson. “In these cases, finance personnel thought they heard the voice of a trusted client or associate and were duped into transferring funds.” But this is by no means a guarantee. The researchers point out in their paper that, even while they were doing the research, GANs got more advanced and generated better fake images than the ones they used in their study. It’s possible that, once the algorithms exist, deepfakers will just figure out ways to circumvent them. “That said, the deepfakes are always being generated by a computer that has an ‘idea’ of what a face is,” says Carlson. “As long as it’s generating these things from this ‘idea’, there might be just the slightest thing that’s wrong. It’s a matter of figuring out what’s wrong with it this time.”  <img id="cosmos-post-tracker" style="opacity: 0; height: 1px!important; width: 1px!important; border: 0!important; position: absolute!important; z-index: -1!important;" src="https://syndication.cosmosmagazine.com/?id=197814&title=Which+of+these+pictures+is+a+deepfake%3F+Your+brain+knows+the+answer+before+you+do" width="1" height="1" />  <div id="contributors"> <a href="https://cosmosmagazine.com/technology/deepfakes-brain-eegs/" target="_blank" rel="noopener">This article</a> was originally published on <a href="https://cosmosmagazine.com" target="_blank" rel="noopener">Cosmos Magazine</a> and was written by <a href="https://cosmosmagazine.com/contributor/ellen-phiddian" target="_blank" rel="noopener">Ellen Phiddian</a>.

Wordle changes answer amid abortion rights debate

The New York Times has swiftly changed the answer to its daily Wordle puzzle out of fear it would be interpreted politically amid the debate on abortion rights in the US. The wildly-popular browser-based game, which was bought by the masthead in January, gives users six attempts to guess a five letter word each day which is chosen in advance and at random by a computer program. On Monday, the Times scrambled to change Monday’s word which was “fetus”, using the American spelling. The word could have been seen as a controversial choice given the <a href="https://oversixty.co.nz/finance/legal/america-s-roe-v-wade-abortion-law-could-be-overturned" target="_blank" rel="noopener">recent leaked report</a> of a draft decision from the Supreme Court to overturn two laws that grant women the right to access abortions. In a message to readers on the same day, the newspaper said the word choice was “entirely unintentional and a coincidence”. “At New York Times Games, we take our role seriously as a place to entertain and escape, and we want Wordle to remain distinct from the news,” the message said. Monday’s word was changed and a spokesman said a “vast majority” of users saw that, save some who hadn’t refreshed their page and saw “fetus” instead. Many New Zealand users reported seeing “fetus”, according to the <a href="https://www.nzherald.co.nz/lifestyle/wordle-answer-changed-to-avoid-fraught-word-ny-times-says/2ZONMXP5ZTIXJGVZR2YMJWHZPI/" target="_blank" rel="noopener">NZ Herald</a>. However, Cohen wouldn’t say whether the Times received any complaints about the word choice. Image: Getty Images

Grieving mother’s plea to finish son’s composition answered

A grieving mother has put out a worldwide call for musicians to finish her son’s first musical composition. 12-year-old Kyan Pennell passed away on January 31st after a tragic accident on his family’s property when he got caught between a trailer and a gate.Kyan’s mum Amanda Brierley said he started learning piano just seven months ago, and unbeknownst to her, had started writing his own music. "The thing that has given us some little part of Kyan to hold onto is when I found this composition he was working on in the middle of a blank exercise book," she told <a href="https://www.abc.net.au/radio/brisbane/">ABC Radio Brisbane</a>. "I didn't realise that he knew how to write music. He said he wanted to know how to get what was inside his head out on paper and he must have been learning how to do that."Amanda said Kyan’s neurodiversity gave him a “superpower” to focus and learn more than 30 classical music pieces in just a few months. Earlier in February, Amanda posted a photo of Kyan’s unfinished work and asked other musicians to help finish it."This was just the intro, it is unfinished," she wrote."He was building up to a grand mid-section and then would do an ending but he never got to complete what was in his mind's eye."He imagined it to be performed by wind and string instruments, and of course his beloved piano."Amanda said she has received dozens of submissions and hoped to collect as many as she could to help honour her "beautiful boy"."Finding this composition was an unexpected gift from him," she said."Unfortunately we never got to hear him play it, so I want the world to be able to play it for me.”"I just want to be able to change his memory from a tragic accident to something of beauty for others as well."Image credits: Facebook / Amanda Brierley

Time to upgrade from cloth and surgical masks to respirators? Your questions answered

With the rapid spread of Omicron, many countries are rethinking their COVID mask advice for the community. Respirators have been mandatory in public places in <a href="https://www.france24.com/en/europe/20210125-austria-makes-ffp2-masks-mandatory-in-shops-public-transport">Austria</a> for a year. Now, the <a href="https://www.cdc.gov/coronavirus/2019-ncov/prevent-getting-sick/types-of-masks.html">United States Centers for Disease Control and Prevention</a> suggests respirators be considered for greater protection, for instance, on public transport or in enclosed crowded spaces. It’s time to rethink and upgrade masks for you and your family. <h2>What is a respirator?</h2> Respirators, often wrongly called “masks” because of their appearance, are personal protective equipment made to a particular standard and designed to prevent inhalation of hazardous airborne contaminants. In the US, respirator standards are managed by the <a href="https://www.cdc.gov/niosh/topics/respirators/">National Institute for Occupational Safety and Health</a> (NIOSH), and cover three things: filter efficiency, breathing resistance and fit. A filter that meets the N95 standard (equivalent to Europe’s FFP2) must capture at least 95% of particles in the most penetrating size range at a high flow rate. In Australia, a respirator must meet <a href="https://www.tga.gov.au/publication/guidance-medicalsurgical-face-masks-and-respirator-standards-key-performance-aspects">TGA standards</a>. A respirator that consists entirely of filtering material – rather than having layers, say for waterproofing – is called a filtering facepiece respirator (FFR). An FFR can be worn multiple times but must eventually be thrown away. Research suggests FFRs lose their ability to fit well after <a href="https://www.ajicjournal.org/article/S0196-6553(11)00770-X/fulltext">20 wears</a> – due to stretching of straps or failure of the nose clip or edge components. The filter material is usually a non-woven polypropylene electret, which means the fibres carry an electrical charge to enhance particle collection while ensuring low breathing resistance. <h2>Why were we told to wear cloth masks at first?</h2> It was initially assumed SARS-CoV-2 spread via droplets (in coughs and sneezes) which caused infection when they landed on the mouth, nose or eyes. For such particles, a cloth or surgical mask is an efficient form of source control to protect others from virus emitted by the wearer. Now it’s understood the virus is <a href="https://theconversation.com/covid-how-the-disease-moves-through-the-air-173490">airborne</a>. Virus-laden particles build up in the air over time indoors because of breathing and speaking. <h2>Will a respirator protect me even if others are unmasked?</h2> It depends on the type of exposure and how long you are exposed. It is important to consider your risk depending on <a href="https://theconversation.com/heres-where-and-how-you-are-most-likely-to-catch-covid-new-study-174473">where you are, what you’re doing, with whom and how long you’re there</a>. The <a href="https://www.cidrap.umn.edu/news-perspective/2021/10/commentary-what-can-masks-do-part-1-science-behind-covid-19-protection">safest situation</a>, especially for prolonged contact in crowded settings, is when everyone is wearing well-fitting N95 respirators. It’s hard to show evidence to support respirator use in the community – but lack of randomised controlled trials (RCT) does not mean they are not effective. Studying masks or respirators at a population level is complex and involves many variables. There is <a href="https://www.sciencedirect.com/science/article/pii/S0020748920301139?via%3Dihub">strong evidence</a> from RCTs in health workers and laboratory studies showing respirators are effective for source control and personal protection. <h2>I really like my cloth mask. Is it OK to keep wearing it?</h2> Probably not. Cloth masks are not made to any particular standard, so their properties and quality vary considerably. In general, they are poor filters of small airborne particles. <h2>Surgical masks are cheaper – can I just switch to those?</h2> Not really. While some surgical masks may have better filtration capacity than cloth masks, they were designed primarily to prevent the emission of large droplets. Some medical-grade surgical masks may also offer protection from body fluid splashes or sprays. No surgical mask will prevent the emission or inhalation of small infectious particles, however. A key deficiency of surgical and cloth masks is their loose fit compared to respirators. While some older, hard-cup style respirators may be uncomfortable, newer styles are <a href="https://www.washingtonpost.com/outlook/2022/01/11/n95-masks-cdc-walensky/">better tolerated</a>. This may be due to their greater surface area, which could contribute to lower breathing resistance. <h2>Should I have my respirator professionally fitted?</h2> No. When respirators are used to protect workers from airborne hazards such as dust or pollution, employers are legally required to undertake fit-testing (see for example the US <a href="https://www.osha.gov/laws-regs/regulations/standardnumber/1910/1910.134">Occupational Safety and Health Administration</a> fit-testing standard). But even non-fit tested respirators will provide <a href="https://onlinelibrary.wiley.com/doi/10.1111/j.1750-2659.2011.00198.x">superior protection</a>over cloth or surgical masks. A respirator should rest against your face with no gaps, especially around the nose and chin. To create a tight seal, form the nose clip and place both straps around your head, adjusting them if necessary. If the facepiece collapses a small amount when you inhale, the respirator probably fits well. Get in the habit of doing a <a href="https://youtu.be/pGXiUyAoEd8?t=140">“self seal-check”</a> before each wear. <h2>Shouldn’t respirators be reserved for healthcare professionals?</h2> No. Early in the pandemic, the public were discouraged from buying respirators because of a global shortage of personal protective equipment and the assumption healthcare workers were at higher risk of catching COVID from so-called “aerosol-generating procedures” such as intubation. We now know <a href="https://associationofanaesthetists-publications.onlinelibrary.wiley.com/doi/full/10.1111/anae.15475">everyday activities like talking and singing</a> are more likely to generate infectious aerosols than medical procedures. As with vaccines, there are global equity issues and we need to <a href="https://www.statnews.com/2021/01/07/national-hi-fi-mask-initiative-needed-with-vaccine-rollouts/">expand manufacturing capacity</a> to ensure sufficient supply for everyone. <h2>What about the cost and environmental impact?</h2> Compared to cloth masks, respirators (which are not washable) cost more and have a greater environmental impact. But disposable respirators can be used for <a href="https://journals.lww.com/md-journal/fulltext/2020/12110/determination_of_the_optimal_time_for_n95.143.aspx">extended periods</a> if they are not wet or damaged, and there are re-usable options such as <a href="https://www.cdc.gov/coronavirus/2019-ncov/hcp/elastomeric-respirators-strategy/index.html">elastometric respirators</a>. A respirator should be thrown away when it gets dirty or the straps, nose clip or other components lose their integrity. Costs and environmental concerns need to be weighed against the costs and waste produced by a single COVID hospital admission. In Australia, the average daily cost of an Intensive Care Unit stay has been <a href="https://www.mja.com.au/journal/2019/211/7/financial-cost-intensive-care-australia-multicentre-registry-study">estimated at $4375</a>. <h2>What if I can’t afford or get my hands on a N95 respirator?</h2> The Korean KF94 and Chinese KN95s are cheaper alternatives that provide better protection than a surgical or cloth mask. <a href="https://www.nytimes.com/wirecutter/blog/12-signs-you-have-a-fake-n95-kn95-or-kf94-mask/?smtyp=cur&smid=tw-nytimes">Beware counterfeits</a>, such as those without a GN stamp to show they meet manufacturing standards. If you can’t get hold of a respirator, you can <a href="https://ozsage.org/wp-content/uploads/2021/09/OzSage-Masks1-4.pdf">improve protection of a surgical or cloth mask</a>. Options include “<a href="https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/2778913">double masking</a>” by wearing a tight-fitting cloth mask over a surgical mask. You can also “knot and tuck” a surgical mask by tying the sides and tucking the remainder inside. Finally, a well-designed cloth mask (with three layers) can perform as well as a good quality surgical mask. It’s still true that something is better than nothing. But don’t count on these types of masks to provide the same level of protection for the same amount of time as an N95 respirator. <h2>Respirators should be provided and required</h2> The World Health Organization has stressed the importance of a “vaccines-plus” approach. There is a strong case, when prevalence of COVID is high, for governments to both mandate and fund the provision of respirators for the public, <a href="https://www.cbs58.com/news/500-000-n95-masks-given-away-in-48-hours-more-on-the-way">as some parts of the US</a> are now doing.
