The UK Health Security Agency (UKHSA) has extended its amber heat-health alert, warning that soaring temperatures across large parts of England could pose a serious danger to older people, young children, and those with existing health conditions. The warning will now remain in force until Thursday, May 28, and has been widened to include the South West alongside the South East and central parts of England.
Extended Alert and Affected Regions
In a social media post, the agency stated: "Amber heat‑health alerts have been extended until Thursday 28 May and now include the South West, alongside the South East and central England. Check in on vulnerable people and know what to do if someone becomes unwell in the heat." According to the alert map, areas covered include London, the South East, East Midlands, West Midlands, East of England, and the South West.
Understanding the Amber Warning
Under the UK’s Heat-Health Alert system, an amber warning indicates that weather impacts are likely to be felt across the wider health service, with possible rises in deaths and illness among vulnerable groups. These alerts are issued when high temperatures are expected to have a significant effect on hospitals, care homes, and other services. Experts warn that extreme heat places extra strain on the body, as the heart must work harder to keep cool.
Health Risks and Symptoms
The agency explained that sweating and increased blood flow near the skin help regulate body temperature, but dehydration can quickly trigger problems such as dizziness, fainting, muscle cramps, and heat exhaustion. Symptoms of heat exhaustion include headaches, nausea, heavy sweating, and tiredness. Older people, pregnant women, children, and those with heart or lung conditions are most at risk. The NHS advises moving anyone suffering heat exhaustion to a cool place, encouraging them to drink water, and cooling their skin with sprays, damp cloths, or ice packs.
Heatstroke: A Medical Emergency
Officials warn that if someone remains unwell after 30 minutes, stops sweating despite feeling hot, develops confusion, or has a temperature above 40°C, these are signs of heatstroke, which is considered a medical emergency. In such cases, people should call 999 immediately. The agency also noted that hot weather can worsen existing conditions including heart disease, asthma, COPD, diabetes, and kidney disease. Certain medications, such as diuretics, beta-blockers, and some antidepressants, can make it harder for the body to cope in high temperatures.
Advice for Staying Safe
Officials advise people to stay hydrated, keep homes cool by shading windows and opening them at night, and avoid overheating indoors by switching off unnecessary electrical equipment. They also suggest spending time in cooler public spaces such as libraries, community centres, and places of worship if homes become too hot. Health officials urge everyone to check on vulnerable relatives, neighbours, and friends during this period of heightened risk.
