Figures disclosed by 33 NHS trusts show temperatures on wards during July rose above 28C limit set by NHS England

Hospitals in England have recorded temperatures of almost 42C this summer, with surgeries being cancelled because operating theatres’ cooling units stopped working in the intense heat.

The Northern Care Alliance NHS foundation trust, which runs four hospitals in Greater Manchester, recorded a temperature of 41.8C during last month’s heatwave – 14C above the recommended safe maximum.

Some patients are also cancelling their own surgery because it is too hot for them to travel.

Hospitals and GP surgeries are offering frail elderly patients appointments at the start and end of the day, when it is less hot, to make it easier for them to attend.

Ambulance services are struggling to keep some medications at the right temperature because it gets so hot in the back of their vehicles.

NHS ambulance trusts have relaxed their usual dress code rules to help crews stay cooler, for example by wearing shorts rather than trousers

Users need discretionary income of nearly £100,000 a year to make savings on their grocery spend after paying £1,200 for GLP-1s, analysis finds

The high cost of weight-loss medication is a “regressive tax on being thin” because the outlay outweighs any saving on food costs for all but the highest earners.

Someone needs to have discretionary income of nearly £100,000 a year to actually save money after covering the £1,200 annual cost of GLP-1 medication, according to an analysis by the consultancy Baringa.

Grifols, which runs private chain of clinics, to temporarily stop taking donations after new government investigation

A chain of private plasma donation clinics in Canada has said it is pausing collections after the deaths of two donors and a new government investigation into potential unsafe practices.

Grifols, a Spanish healthcare company which runs 17 clinics in Canada and is the country’s only private clinic for plasma donation, said it informed Health Canada of its decision to temporarily pause collections on Wednesday.

If you’re trying to meet your daily serving of 2.5 cups of vegetables, you might have some questions

If you want to eat lettuce, that no longer just means iceberg. In our bountiful age, there are many options: romaine, red-leaf lettuce, butter lettuce, beet greens, bok choy, bitter radicchio, every developmental stage of arugula.

Sometimes, it’s simply up to preference. But if you’re trying to meet your daily serving of 2.5 cups of vegetables – or you’re rethinking your salad choices amid the US cyclospora outbreak, you might have some questions about which greens to go with.

Debilitating symptoms lead some to try over-the-counter medications Allegra and Pepcid due to a social media trend

Premenstrual dysphoric disorder (PMDD) and menopause can come with debilitating symptoms, like intense emotional changes and exhaustion.

All over social media, women are claiming that a simple hack has helped enormously: a combination of two over-the-counter medications, both antihistamines – typically, the name brands Pepcid AC and Allegra.

Doctors and nurses describe rise in fall injuries and other heat-related problems on top of stifling working conditions

“The big thing A&E doctors are seeing during extreme heat now is falls in the elderly,” says Dr Adrian Boyle, an A&E consultant at Addenbrooke’s hospital in Cambridge.

“During this summer’s five heatwaves I’ve seen elderly people get light-headed and dizzy and fall down a whole flight of stairs and break multiple bones, purely because of the heat. The last fall down stairs because of the heat resulted in multiple broken ribs, a wrist and her lower leg.

NGOs say agreement held back by tenuous human health commitments and lobbying from plastic industry

The latest version of the long overdue plastic treaty is even less ambitious than the previous one, according to experts.

A year after UN plastics treaty negotiations collapsed in Geneva in 2025, diplomats met informally in Nairobi between 30 June and 3 July, aiming to flesh out a new “no surprises” document.

President’s order calls for several changes to childhood vaccinations – and experts say it’ll lead to confusion

On Monday, Donald Trump signed an executive order pushing for revisions to how children in the US are vaccinated.

The executive order calls for several changes. These include fewer vaccinations overall and a recommendation that the combined measles, mumps and rubella (MMR) vaccine be replaced with separate shots for each disease administered during separate medical visits. The latter direction is currently impossible to implement because no stand-alone shots for these diseases are licensed in the US.

Letícia Rodrigues takes on the titular challenge in this show about shame, rage and how female bodies are surveilled

A smiling woman steps on to the weighing scales in front of the stage. She is glamorous with bobbed blond hair, gleaming nails and a trendy red trouser suit. She is exactly 84kg, she states. It is an opening gesture reminiscent of an old-school diet club like the one her mother first took her to at the age of eight.

Letícia Rodrigues’s show is autobiographical, albeit dramatised through a character called Gorda who, like her, is Brazilian and has been deemed overweight for most of her life. So she is planning to lose the fat in each of her shows. The weigh-in will be followed by a weigh-out at the end of the hour. The goal is to be 116 grams thinner and so the show is also a training session, she says.

Mike Pender responds to an article by Felicity Lawrence in which she reflects on why food firms are panicking and suing

Felicity Lawrence’s alarming piece on ultra-processed foods (Why are ultra-processed food firms panicking and suing? Because they know time is running out, 7 August) made no mention of the UK’s Food Standards Agency, whose primary statutory objective is to protect public health from risks arising from the consumption of food.

The FSA is an independent, non-ministerial government department. Its advice to ministers, and guidance to consumers, is informed by the most up-to-date scientific evidence, free of political or commercial considerations.

Bill Hunter says the weekly 5k race at locations across the UK and beyond is for everyone, and should be celebrated, while Helen Beioley says it is the perfect excuse to meet friends and consume a croissant after

I am sorry that the parkrun spoils Janet Knowlson’s experience of her local park (Letters, 7 August). I wonder if she has ever spoken to a parkrunner or a volunteer? Many would tell of the camaraderie and their improved physical and mental health. Strangers become friends and even partners. We do not take over the park, as she alleges, rather we recognise that we share the space with other park users and are respectful of their rights and needs. Parkrun is for everyone and anyone, from children upwards, and not only runners. It is only competitive if you want it to be, and is equally welcoming to walkers. Parkrun is a huge success story, both in the UK and many other countries, and should be celebrated. It receives no public funding and each event relies on an army of volunteers, without whom it wouldn’t happen. Long may it continue.

• In response to Janet Knowlson’s letter complaining about the disruption to her daily peaceful walk through her park by parkrun, please can I suggest that she avoid just this one specific hour a week? Parkrun is an inclusive joy for hundreds of thousands of runners and walkers of all shapes, sizes, ages and levels of fitness. For me, it’s the perfect excuse to meet up with mates and wallop down a huge almond croissant as a post-run(walk) reward.

The Reform UK leader resigned as the MP for Clacton at the start of July and forced a byelection

The number of patients in England being cared for in hospital corridors or makeshift areas has remained above 3,000 a day for the second month in a row, as the NHS experiences a “summer surge”, the Press Association reports.

This was happening as A&E attendance numbers reached 2.5m in July – higher than any other single month on record. May and June were also record months for A&E attendance, in part because of the extreme heat.

Yvette Cooper, the health secretary, warned yesterday the health service must start planning for summer pressures in the same way as winter.

However, the data shows overall waiting times for treatment fell slightly in June after rising for two months in a row.

The NHS normally experiences spikes in demand during the summer months, as the public spends more time outside which can lead to a rise in accidents. But this summer has seen unprecedented pressure, with the heat contributing to an increase in admissions caused by more outdoor activity and respiratory issues linked to dry weather, as well as worsening of underlying medical conditions.

The first minister is right to ask about this. This is 1,500 jobs in the north of Scotland. It’s also an area that is being transformed by that move towards offshore renewables, Scotland continuing to contribute.

It’s an area which is, in general terms, important for security. Scotland is contributing to European energy security, which is a concern across Europe when you speak to leaders there.

State is US’s largest user of pesticide that is virtually proven to cause Parkinson’s disease

California is banning paraquat, a highly toxic, controversial herbicide used across millions of acres of American cropland.

Public health advocates characterize it as a deadly substance that is virtually proven to cause Parkinson’s disease. It is already outlawed in more than 70 countries, including China, the UK and the EU. Yet in the US, the Environmental Protection Agency (EPA) reapproved it for use in 2021 and 2024.

Move blocking funds through Medicaid and Chip to make it harder for vulnerable children to get healthcare, experts say

The Trump administration finalized a rule on Tuesday to end gender-affirming care through Medicaid and the Children’s Health Insurance Program (Chip), a move that will make it harder for vulnerable children to access healthcare and that eschews evidence to advance an anti-transgender ideology, opponents say.

The rule is set to take effect on 13 October – but legal challenges could delay or block it entirely.

The order cannot effect change, and is only ‘undermining trust in vaccines’ as CDC guidance remains the same

Donald Trump’s executive order on vaccines does not change the US recommendations for the shots – but experts say it does create confusion and doubt about vaccines, which will lead to more illness and possibly deaths among children and will make it harder for families and pediatricians to protect them.

The executive order was an attempt to reinstate sweeping changes to the vaccine schedule made earlier this year by Robert F Kennedy Jr, secretary of the US Department of Health and Human Services and a longtime vaccine opponent – changes that were later halted by a federal judge.

How can our understanding of mortality shape the way we live? Palliative care doctors and death doulas share the lessons they have learned

We will all face death one day, but our attitude towards this is individual. How can our understanding of mortality shape our approach to life? Here, palliative care doctors and death doulas share what they know about the end – and how it informs the way they live.

Dress like a zebra, wash your feet, keep off the beer: insect experts explain what works and what doesn’t – and why some of us get bitten more than others

It’s a good time to be a mosquito or other blood-sucking insect. In the UK and beyond, they are enjoying the summer heat, and there are lots of humans outdoors, some wearing very little, like an all-you-can-eat walking buffet. Some of the humans are drinking beer, which apparently makes them even more irresistible to mosquitoes. Many of us are warm and sweaty, which is all the better for the blood-suckers seeking us out.

Insect populations are changing because of the warming climate and there are organisations keeping an eye on invasive species, especially mosquitoes, which can be vectors for diseases such as dengue and malaria (globally, more than 600,000 people a year die from malaria). The UK “will have a threat from mosquito-borne diseases as time goes on,” says James Logan, professor of medical entomology at the London School of Hygiene and Tropical Medicine, and CEO of Dot, an “odour intelligence” company. “The biggest threats are arboviruses [viruses transmitted by arthropods, especially insects and ticks], such as dengue. We have mosquitoes throughout [mainland] Europe now that can transmit dengue. We also know that we do get those mosquitoes coming across to the UK, but they don’t seem to be breeding here successfully and surviving over the winter.” But, he warns, with milder winters and warmer summers, it is only a matter of time.

Biological factors mean a child’s core temperature rises faster than an adult’s – and that can result in a medical emergency

Children and babies are more vulnerable in heatwaves than healthy adults. As temperatures rise again, how do we keep children safe?

PM warns extreme heat conditions ‘could be with us fo some time yet’

Just 20 staff are working on climate adaptation within the Department for Environment, Food and Rural Affairs, the part of government tasked with protecting the environment and maintaining food security, a freedom of information request has revealed. Sandra Laville has the story.

On his visit to Stevenage, Andy Burnham also said he would visit the town on Remembrance Day to mark its 80th birthday.

I’m going to come back to Stevenage on 11 November. We will pay our respects for Remembrance Day around that time, but I’ll be here because if I’m right, that will be 80 years to the day that the post-war Labour government created the first new town right here in Stevenage.

Calls for speed limiters or mandated helmet use after research into injuries at three paediatric trauma centres

The number of children involved in crashes on e-scooters has soared in recent years, with some as young as nine involved in collisions, research has found.

Researchers carried out a review of injuries among the under-16s at three specialist paediatric trauma centres – Alder Hey in Liverpool, and Sheffield and Royal Manchester children’s hospitals – between January 2019 and December 2024.
