Brits have been urged to take precautions as health chiefs issued a heat health alert warning that soaring temperatures could put thousands of vulnerable people at risk.
The UK Health Security Agency (UKHSA) says the hot spell raises the danger of dehydration, heat exhaustion and potentially fatal heatstroke, particularly among older people, young children and those with underlying health conditions. A UKHSA spokesperson said: “Hot weather can be dangerous, especially for the most vulnerable in our communities. It is important that everyone takes simple steps to stay cool and hydrated.”
Officials are warning people to avoid strenuous activity during the hottest part of the day, keep homes cool and drink plenty of fluids as temperatures climb.
The alert comes amid growing concern over the impact of extreme heat, with climate experts warning that hot weather events are becoming more frequent and intense. Professor Hannah Cloke, a climate scientist, said: “We are seeing a clear trend towards more frequent and intense heatwaves, which poses a growing risk to public health.”
UKHSA said anyone can become unwell if they get too hot, but those most at risk include people aged 65 and over, babies and young children, pregnant women and those suffering from conditions such as heart disease, breathing problems, diabetes and dementia.
The agency has also highlighted the risks faced by outdoor workers, runners, cyclists and people who are homeless or living in accommodation that is difficult to keep cool.
Health officials are advising people to avoid direct sunlight between 11am and 3pm, when ultraviolet levels are strongest, and to wear suitable clothing, hats and sunscreen when outside.
People are also being urged to check on elderly relatives, neighbours and friends who may struggle to cope with the heat.
As temperatures rise, Age UK is reminding older people not to underestimate the dangers posed by extreme heat.
Caroline Abrahams, charity director at Age UK, said: “Older people can be particularly vulnerable in hot weather, so it’s vital they stay hydrated, keep cool and avoid the midday sun.”
The warning underlines the growing health threat posed by rising temperatures. According to UKHSA, an estimated 2,803 people aged 65 and over died as a result of heat in England during 2022, the year Britain recorded temperatures above 40C for the first time.
Experts warn the annual number of heat-related deaths could triple by 2050 if temperatures continue to rise. A recent report noted: “Without significant action, heat-related mortality is projected to increase substantially in the coming decades.”
Hot weather can place additional strain on the body, increasing the risk of heart attacks, strokes and respiratory problems.
The agency said many heat-related illnesses are preventable if people take simple precautions, including drinking water regularly, keeping curtains closed in sun-facing rooms and opening windows at night when temperatures fall.
It also warned against leaving children, older people or pets in parked cars, which can become dangerously hot within minutes. One of the biggest dangers is heatstroke, a medical emergency that occurs when the body can no longer cool itself down.
Symptoms include confusion, rapid breathing, a fast heartbeat and hot skin that is no longer sweating. Anyone suspected of suffering heatstroke should be cooled down immediately and 999 called without delay.
UKHSA said it will continue to work with the Met Office throughout the summer to issue heat health alerts whenever temperatures are forecast to reach levels that could threaten public health.
The agency’s advice is simple: “Stay out of the midday sun where possible, drink plenty of fluids, keep homes cool and check on those who may be vulnerable as the mercury rises.”
