About 570 people in England and Wales are expected to die as a result of high temperatures from Thursday 19 June 2025 to Sunday 22 June 2025, a rapid study is estimated.
It is the first real -time analysis in 2025 for excessive heat deaths by researchers at the London School of Health and Tropical Medicine (LSHTM) and Imperial College London.
The study uses decades of data in the United Kingdom to understand risk relationships in 34,753 areas across England and Wales to predict excessive mortality during this hot energy.
Overall, about 570 excessive deaths are expected to occur during the hot wave, researchers estimate, with 114 on Thursday 152 on Friday 266 on Saturday, when temperatures peak over 32 ° C and 37 excessive deaths on Sunday when they fall in mid -twentieth.
The elderly over 65 are expected to hit harder, with 488 than estimated excessive deaths. Of these, 314 are expected to be among people aged 85 and over, according to researchers. The result shows that thermal waves can be fatal for people with underlying health conditions, such as heart problems, diabetes and respiratory problems, as high temperatures give additional stress to their already compromised immune system, the researchers say. However, they warn that heat can become life-threatening for all ages, as 82 deaths are appreciated for people at the age of 0-64.
The analysis also revealed London is expected to have the highest number of excessive deaths with 129, followed by western Midlands with 106 deaths and southeast with 81. The difference is mainly due to where heat is more extreme. However, researchers say people living in degraded areas can experience higher heat -related death rates because they have poorer health, housing and health care.
The increases of one or two degrees can be the difference between life and death. When temperatures promote the limits of the populations are acclimated, excessive deaths can increase very quickly.
A large number of excessive deaths would probably not happen without climate change. More research is required to give an estimate.
Clearly, a warmer climate is a more dangerous climate. Each fraction of a degree of heating will cause more hospital entrances and heat deaths, putting more pressure on NHS. ”

Dr. Garyfallos Konstantinoudis, Lecturer at the Grantham Institute – Climate change and the environment, Imperial College London said:
“The burning of thermons are silent murderers – people who lose their lives usually have pre -existing health conditions and rarely have heat that is referred to as a contribution of death.”
“This real -time analysis reveals the hidden burner tax and we want to help increase the alarm.”
“Hot waves are an undervalued threat in the United Kingdom and are becoming more and more dangerous with climate change. This weekend, people need to follow heat tips and control the elderly, especially those who live alone.”
Dr. Malcolm Mistry, Assistant Professor at LSHTM, said:
“Our study should be taken as a warning. Exposure to temperatures at high 20 or low 30s may not appear dangerous, but may be fatal, especially for people over 65 years, infants, pregnant and those with pre -existing health conditions.
“Unless effective mitigation and adaptive measures are implemented in the coming years, the risk of major heat -related death events is expected to increase in the United Kingdom – we have a large population aging and heating is expected to increase to 2 ° C by 2050 and up to 3 ° C this century.
This evaluation emphasizes how extreme heat is an increasing threat to public health in the United Kingdom, followed by a study published on Friday found by Heatwave about 10 times more likely and 2-4 ° C warmer due to climate change.
This week, the United Kingdom has experienced intense and prolonged heat. On Tuesday, the UK Health Safety Service issued a yellow thermal health warning to warn vulnerable health risks to the rising temperatures. By noon on Thursday, the situation escalated with a more serious amber covering all over England, warning of “increased deaths”. Shortly thereafter, dozens of people needed heat -related disease treatment in Royal ASCOT matches, as temperatures pushed over 29 ° C.
To estimate how many additional deaths could occur during hot temperatures from Thursday to Sunday, researchers used findings from published research on the relationship between heat and the number of daily deaths, regardless of the cause, in 34,753 small areas. They combine these mortality risk functions with high -resolution prediction from Copernicus to assess how many heat -related deaths will occur for four days in June.
An estimate of 570 deaths is aligned with a previous study that estimates about 1,100 deaths during the extreme boat from July 17-19, 2022, when temperatures reached 40C in the United Kingdom for the first time, the researchers say. They also note that the analysis does not represent the effect of the hot wave that occurs in early summer before people are acclimated to hot temperatures, which means that heat deaths could be underestimated.
Climate change, mainly caused by the burning of fossil fuels, has already been shown to lead to large increases in heat -related deaths. For example, about 56% of the 68,000 heat -related deaths during the European summer of 2022 were caused by climate change, according to the study. Findings reflect how small heat increases can cause huge increases in deaths when hot temperatures push people to their normal limit, the researchers say.
Researchers say that a large number of UK excessive deaths would not happen without the heat reinforced by climate change – temperatures are about 2-4 ° C warmer due to the global weather performance on Friday. However, they say that it is unlikely that the number of climate change is higher than 50%, as reported in Europe where populations are vulnerable and storm intensity increases faster than the United Kingdom.
A recent report by the United Kingdom Change Committee estimates that heat -related deaths could rise to over 10,000 in an average year by 2050 if continuing fossil fuel burning causes 2 ° C.
