Reduced physical activity due to global heating will lead to rise in health issues, study says. Guardian Chloe Farrand 16 Mar 2026 Researchers project that reduced activity could contribute to half a million additional premature deaths annually by 2050. Rising temperatures are making physical activity undesirable and even dangerous in many parts of the world, and as global heating worsens, it will further affect how much people are able to move. Researchers analysed data from 156 countries between 2000 and 2022 and modelled how rising temperatures may affect physical activity globally by 2050.They found that each additional month with an average temperature above 27.8C would increase physical inactivity by an average of 1.5 percentage points globally, with an even higher increase of 1.85 points in low and middle-income countries.
Christian García-Witulski, a research fellow at the Lancet Physical inactivity increases the risk of cardiovascular disease, type 2 diabetes, certain cancers and mental health disorders, all of which shorten life expectancy, said the study’s lead author, Countdown Latin America and a professor at the Pontifical Catholic University of Argentina. Reduced physical activity is already a big global health problem and is responsible for an estimated 5% of all adult deaths, according to the study, which was published in the Lancet Global Health journal. About a third of the world’s population fails to meet World Health Organization guidelines for weekly exercise.The study projects that the increase in physical inactivity could contribute to about half a million additional premature deaths annually and $2.4bn – $3.68bn in productivity losses by 2050.
The biggest increases in inactivity are projected to be in hotter regions such as Central America, the Caribbean, eastern sub-Saharan Africa, and equatorial south-east Asia, where inactivity could rise by more than four percentage points a month. “This is not just a climate story, it is also an inequality story. The places expected to face the greatest increases in climate-driven inactivity are often the same places with fewer resources to adapt,” said García-Witulski. “In settings where people have less access to cooling, fewer safe indoor alternatives, and less flexibility in their daily schedules, heat appears more likely to translate into reduced physical activity.” The model also predicted a bigger increase in inactivity among women, which could reflect physiological differences as well as social factors, such as less time and access to cool places for exercise, said García-Witulski......read on https://www.theguardian.com/environment/2026/mar/16/reduced-physical-activity-due-to-global-heating-rise-health-issues-study

But the impact is not evenly felt. In Asia, heavily reliant on the Middle East for crude oil and liquefied natural gas, Bangladesh closed all its universities and Pakistan some of its schools due to fuel shortages. While US coverage is dominated by the impact at home, others are paying a higher price. And it is the world’s poorest and most vulnerable who will be the worst hit. The war has created a new humanitarian crisis – with millions displaced in Iran and Lebanon, and healthcare facilities hit as well as more than 17,000 residential buildings, according to Iran’s Red Crescent. But it is also deepening existing ones, and it comes as US cuts to aid – and reductions by Britain and others – are already pushing millions deeper into hunger.
In Gaza, food prices have surged after Israel closed crossings. The World Health Organization, the International Federation of Red Cross and Red Crescent Societies and others are struggling to ship essential aid from the region: Dubai is home to a major humanitarian logistics hub and the Middle East’s largest container terminal – which caught fire after it was struck by wreckage from an intercepted Iranian missile.......but the weapons manufacturers are making a killing! so to speak. read on https://www.theguardian.com/commentisfree/2026/mar/12/the-guardian-view-on-the-cost-of-trumps-war-the-worlds-poor-will-pay-most-dearly

Doctors Without Borders/Médecins Sans Frontières (MSF) doctors, nurses, logisticians, project managers and many other professionals work together to in more than 75 countries around the world.
Essential costs There are essential costs for any organization and a small percentage of the money we raise – just five per cent – is used for salaries and running costs in Canada. Another 16 per cent is reinvested in fundraising to keep the money coming in for our overseas work (and for every dollar spent we receive five dollars back). The rest pays for healthcare.- Details

Household burning of plastic waste in developing world is hidden health threat, study shows. The practice is ‘much more widespread’ than previously realised, researchers say, with serious environmental impact. Guardian Donna Lu 8 jan 2026The household burning of plastic for heating and cooking is widespread in developing countries, suggests a global study that raises concerns about its health and environmental impacts.
The research, published in the journal Nature Communications, surveyed more than 1,000 respondents across 26 countries. One in three people reported being aware of households burning plastic, while 16% said they had burned plastic themselveRespondents worked closely with low-income urban neighbourhoods and included researchers, government workers and community leaders. Dr Bishal Bharadwaj, the lead author of the study and a research associate at the University of Calgary, said the work provided broad global evidence on households burning plastic, a practice that had been “difficult to get accurate data on”.
“When families can’t afford cleaner fuels and have no reliable waste collection, plastic becomes both a nuisance and a last-resort energy source. We found evidence of people burning everything from plastic bags and wrappers to bottles and packaging, just to meet basic household needs,” Bharadwaj said in a statement. “The practice is far more widespread than anyone realised, but because it happens in marginalised communities and is often hidden, it has escaped meaningful global attention despite the severe risks to health and the environment.”
The researchers surveyed people in low- and middle-income countries in Asia, Africa and Latin America, and suggest that plastic burning “does not result solely from energy poverty, but also represents a vital informal solution in many settings to cope with … a high rate of mismanaged plastic”. The study’s authors highlighted health risks such as inhalation of toxic emissions in confined spaces as well as contamination of food. Burning plastic releases noxious compounds such as dioxins, furans and heavy metals, while previous research has identified toxic compounds in egg samples near plastic burn sites.
The researchers described the work as “an initial step toward filling critical knowledge gaps in this domain”, but noted that more work was needed to give a true sense of the “scale and distribution of plastic waste burning”. https://www.

The risks desperate Vancouver renters are taking to secure housing. Renters are increasingly agreeing to share a room, often with people they just met online. Vancouver Sun Sage Smith Jan 05, 2026 When Hansley Ambia rented a room in Vancouver, he had no idea that, like many other desperate renters, he would have to agree to no rental protections, poor living conditions, and even to sharing a room with a stranger — or risk losing his housing. The TRAC website states that with shared housing only the “head tenant” is protected by the Residential Tenancy Act, and warns “always try to enter into a tenancy agreement with the landlord of the property — not just another tenant.” “Occupant/roommates” have no dispute-resolution mechanism and would have to go to court to settle conflicts, something few people have the means or ability to do, Patterson said. The use of head-tenants “does add another layer of disenfranchisement and disempowerment of folks who are just roommates, or deemed ‘occupants’ by the Act,” he said. The TRAC website states that with shared housing only the “head tenant” is protected by the Residential Tenancy Act, and warns “always try to enter into a tenancy agreement with the landlord of the property — not just another tenant.” “Occupant/roommates” have no dispute-resolution mechanism and would have to go to court to settle conflicts, something few people have the means or ability to do, Patterson said. Pelaez Aguilar, he later learned, was the “head tenant”. He found occupants and collected rent for the rental management company Sunwise Property, which managed the property on behalf of the property’s owner.
