Researchers have projected that the current heatwave sweeping through England and Wales could result in approximately 600 fatalities. Specialists from the London School of Hygiene & Tropical Medicine (LSHTM) and Imperial College London drew on historical UK data to estimate deaths attributable to the scorching heat expected from Thursday to Sunday.
Their report, issued on Saturday, suggests nearly 570 individuals could perish due to the extreme temperatures during this period. It is forecasted that Saturday will witness the highest number of heat-related deaths, around 266, coinciding with the anticipated peak of the weather's severity.
‌
Particularly hard-hit, London is expected to see as many as 129 extra mortality cases.
‌
The scientists stressed that their analysis underlines the escalating danger posed by severe heatwaves to the public health of the nation.
This announcement comes on the back of a publication by World Weather Attribution (WWA) on Friday, indicating that climate change has made such heatwaves up to 100 times more probable and increased temperatures by 2-4C.

Dr Garyfallos Konstantinoudis, an academic at the Grantham Institute at Imperial College London, remarked: "Heatwaves are silent killers – people who lose their lives in them typically have pre-existing health conditions and rarely have heat listed as a contributing cause of death."
He urged that the real-time assessment aims to expose the often-overlooked consequences of heatwaves and serve as a call to action.
Stressing the severity of the situation, he added, "Heatwaves are an underappreciated threat in the UK and they're becoming more dangerous with climate change."
‌
Dr Konstantinoudis has issued a stark warning for individuals to heed heat-health advice this weekend and to check on the elderly, especially those who live alone.
An amber heat-health alert has been activated across England by the UK Health Security Agency, cautioning vulnerable groups about health dangers, including "a rise in deaths". Meanwhile, parts of Wales officially hit a heatwave on Friday. You can read more about that here.
Royal Ascot saw numerous attendees needing medical attention for heat-related ailments on Thursday.
‌
Utilising data from published studies on the link between heat exposure and daily mortality rates in 34,753 English and Welsh regions, researchers have made some concerning predictions.
By integrating these findings with detailed weather projections from the Copernicus climate change service, they've calculated potential heat-related fatalities.
Their estimates suggest that there could have been 114 excess deaths on Thursday, 152 on Friday, 266 on Saturday, and 37 on Sunday as temperatures are expected to drop to the mid-20s.

It is anticipated that individuals over 65 will be most affected, with 488 of the projected excess deaths impacting this age group, according to the report.
However, the experts also caution that heat poses a risk to life across all age groups, with an estimated 82 deaths among those under 65.
‌
Furthermore, the analysis does not consider the impact of the heatwave striking early in the summer before people have become accustomed to the heat, which could mean the actual death toll may be higher than predicted.
A recent report from the UK Climate Change Committee has projected that heat-related fatalities could surpass 10,000 annually by 2050 if global warming reaches 2C due to continued fossil fuel consumption.
This week, UN experts have sounded the alarm, stating that the world is at a critical juncture to curb warming and has only three years to prevent average global temperatures from rising above 1.5C.
‌
Professor Antonio Gasparrini from the London School of Hygiene & Tropical Medicine (LSHTM) commented on the severity of the situation: "Increases of just a degree or two can be the difference between life and death."
He further highlighted the impact on health services: "Every fraction of a degree of warming will cause more hospital admissions and heat deaths, putting more strain on the NHS."
Dr Malcolm Mistry, also from LSHTM, emphasised the risks associated with seemingly moderate temperatures: "Exposure to temperatures in the high 20s or low 30s may not seem dangerous, but they can be fatal, particularly for people aged over 65, infants, pregnant people and those with pre-existing health conditions."
‌
He warned of the increasing dangers without prompt action: "Unless effective mitigation and adaptive measures are put in place in the coming years, the risk of large heat-related death events is set to increase in the UK – we have a large ageing population and warming is expected to increase to 2C by 2050 and as high as 3C this century."
Dr Lorna Powell, an NHS urgent care doctor in East London who did not participate in the study, shared her observations from the front line: "We are seeing cases of heat-related illnesses rising in our urgent care departments."
She described the rapid escalation of symptoms: "Heat exhaustion can quickly trigger more serious illnesses as dehydration sets in and the cardiovascular system becomes overwhelmed."

What Royal Ascot racegoers had to buy to avoid breaking rules in intense heat

Royal Ascot concluded on Saturday but some racegoers were caught out by the lesser known dress code rules which left them needing to buy socks if they wanted to attend Royal Ascot stuck to its dress code as they enforced some of the lesser known rules by telling racegoers that they had to buy socks if they arrived without them. Few were aware that socks were compulsory with several being caught out. In the Royal Enclosure and men must wear a jacket, collared shirt and tie and also socks. Royal Ascot states that 'socks must be worn at all times' and they should be 'covering the ankle'. Meanwhile ladies have to wear a hat or headpiece with a base of at least four inches. ‌ The dress code is more relaxed in the other two enclosures, but still strictly enforces those rules. Images began doing the rounds on social media of men going into a changing room and buying socks for £5 if they were caught out by the dress code. ‌ The summer event, which is a highlight in the racing calendar, has stuck rigidly to his traditional dress code for years. Despite soaring temperatures this week there was no changes to the rules as the weather resulted in 30 degree days. It is officially the hottest week of the year and while Ascot provided them with water, their uncompromising dress code stayed intact. Back in 2022 the outfits rules were relaxed slightly due to high temperatures, but this year they instead provided free water at hydration stations whilst bottled water was handed out as people left the venue. Those who attended on Saturday saw the last of five days racing in Berkshire with the meeting always attracting some of the world's greatest horses. Jockey James Doyle claimed victory in the week's second Group 1 sprint, but had to wait in the winner's enclosure for his horse. France got the better of Japan with the front-running Lazzat holding off the late charge of Satono Reve in the Queen Elizabeth II Jubilee Stakes. But after crossing the line the winning horse ejected Doyle and went for an extended run of the Ascot racecourse. It led to an unprecedented wait for the winning horse, rider and trainer Jerome Reynier. It was the King and Queen waiting to present the award and Doyle took full responsibility for keeping them waiting. "I did apologise to the King and Queen when I went to collect my prize," he said. "I told them I should have stayed in Pony Club longer than I did, so we had a good laugh about it! I have to say that's a first for me. It's a shame because it would have been nice to come back with the horse in tow." The Group 2 Hardwicke Stakes was claimed by the favourite Rebel's Romance as Charlie Appleby enjoyed more success. One of the longest priced winners of the day came in the Jersey Stakes as Noble Champion won at 25/1.

The truth about palliative care

Watching MPs debate the Terminally Ill Adults Bill in recent weeks has left me and fellow clinicians wondering how many of them have been to a specialist palliative care unit. It has raised a concern about whether people understand what palliative care actually provides, and what we clinicians actually do. How many people have an idea about what hospices and palliative care teams can help with, and would knowing more about such services strengthen calls to make them core parts of NHS provision? Palliative care and assisted dying have seemed in opposition in recent weeks, with people picking sides as though they were rival football teams. I work in a sector that has had to rely heavily on charity and fundraising, which only goes so far. Last year was one of the worst in terms of fundraising for one of our local hospice charities. Palliative care is about living, joy, fun and thinking about your legacy Specialist palliative care in all settings is in a crisis of under-resourcing. We know that palliative care provision is patchy, and inequitable, with some geographies, settings and patient groups receiving completely unacceptable levels of care. Many don't have seven-day on-call cover, when the reality is that crises at the end of life can occur at any time of a given week. Palliative care is not all about inpatient hospices for those who are in the last days of life. We have (in some parts of England and Wales) community teams, outpatient clinics, support teams in general hospitals, day services and out-of-hours on-call provision. We often get involved from diagnosis onward, get to know some patients over several years, and even discharge them again if they feel better and their symptoms improve. And when it comes to dying, most deaths are uncomplicated. Many will not require much more involvement than good local district nursing teams and their usual GP care if systems are working locally. We in palliative care probably need to do far more to dispel some of the narratives that many recent bad death anecdotes have brought up in the assisted dying debate. Yes, bad deaths certainly happen, but many people die peacefully each week, and such 'ordinary dying' is, of course, not reported on. In England and Wales in 2023, over 500,000 deaths were registered. Even ten bad deaths amongst those would be newsworthy, of course, but it does not constitute a norm. It was different when I was a junior doctor in the early 2000's, when I saw some very bad deaths and there was zero palliative care provision in some of the English hospitals I worked in. Hospices being described as full of dying patients, their pain poorly controlled and their senses dulled with high-dose morphine drips, is not the reality. The '20 bad deaths a day' statistic that was highlighted by assisted dying pressure groups has been debunked as unreliable. And faecal vomiting, so vividly described by some MPs, is more talked and written about than it is actually seen on wards and in communities. When I worked at our local hospice, over half the inpatients would be discharged back home again after they had received help with their symptoms. This was often a surprise to them, because many appeared to assume that you never really leave a hospice alive. Some of the older images of hospices full of dying people seem to prevail in the collective memories, when in fact modern-day 'palliative care inpatient units' actually have a rather different role. The same goes for palliative care more generally: much of it happens in the community. I have seen many of my palliative clinic patients for years, and they live life alongside their terminal illness. Always knowing that time may be short, perhaps one pneumonia away from potentially dying, but equally living life to the full whilst they still can, jetting off on holiday, or going clubbing, hiking, cycling and working, and generally being part of their local communities. One of my younger patients recently told me in a video consultation that she just doesn't fit the 'image of a cancer/palliative patient' that people in her environment have come to expect. Many of my patients hold jobs and are on reasonable doses of morphine or oxycodone, without too much in the way of side effects, so they can actually get on with their lives. They drive their cars, perfectly legally. We also review whether they still require the meds, sometimes weaning them off opioids once a reversible pain crisis is over. All this makes predicting a diagnosis of less than six months with any form of accuracy quite hard. The recent debates have made many of us working in this area feel somewhat downhearted, partly because there are a lot of clichés about this area of work that will just never go away. But it has made us think about ordinary 'living with dying' in our society, and how we show that it can be done well. Some of us try our best to frame this world in a more positive light, and I know quite a few patients who are quite happy to help in this, which of course is a good start. A number of my patients have agreed to become part of information campaigns to talk far more positively about palliative care and living with dying, including good advance and future care planning for when their illnesses progress. We have produced videos together on why you may want to consider having a plan for when you become less able to communicate your views, or are getting closer to the end. Sound dreary? Not if you take my patient Keith's approach to it, who sold tickets to his own funeral party. A lot of palliative care clinicians, including Dr Kathryn Mannix with her books (including With the End in Mind) have sought to demystify this area of life and also to inject a bit of much-needed humour and warmth into 'ordinary dying'. It's poorly understood, and people like to brush it away. With assisted suicide, it now risks being medicalised even further and also brought forward quite considerably for some people. News and media narratives don't always help: 'All the medical care stopped and then the patient was for palliation only' or 'They were then just for palliative care'. If 'no longer for active care' means they are now for palliative care, I invite anyone to join our very active ward rounds with patients who receive blood transfusions, iv antibiotics, immunotherapy and scans, all within balance and reason and in close consultation with patients and families. We actively review and discharge some of our patients because, whilst they may have a disease that will likely be life-limiting and their risk of dying is that bit higher, they may still have years ahead of them. Amongst some of my patients and their families, this sometimes raises a chuckle. 'We thought: palliative care, that's it, just a few more days…' Not so. Recent heated debates may have left some with the impression that most deaths in the UK are bad, that palliative care cannot do anything and that hospices are ghoulish places that only give morphine infusions. Think opium den, just with doctors and nurses. This is completely wrong. Palliative care is evidence-based, follows guidelines and reduces strong opioids as much as it starts or increases them (careful titration according to evidence-based guidelines). Palliative care can bring cheer; it brings out the best in people, thinking outside multiple boxes and helping people focus on important achievements in life: getting rid of a nasty infection with intravenous antibiotics, getting a blood transfusion to improve anaemia, receiving immunotherapy from the oncologists, radiotherapy, being pain-free to go for a bracing walk in the Cotswolds, getting to a Millwall game, getting married in Vegas, getting to a Slipknot concert, just being yourself. Whether you've got six days, six weeks, six months or six years left to live (and who knows?). Wherever you stand on matters like assisted dying, good palliative and end-of-life care should never be under-prioritised. We need better funding and in parallel we need to convey very clearly that palliative care is about living, joy, fun, thinking about your legacy and working with a team to get on top of the big challenges. It's only a little bit about dying. Let's call it assisted living.
