LONDON — The UK government has called on the NHS to prepare for recurring summer heat emergencies, warning that extreme temperatures are becoming a long-term challenge for Britain's healthcare system. The move follows successive heatwaves that placed hospitals and emergency departments under significant pressure this year.

Health officials said rising temperatures are increasing the number of patients requiring treatment for heat exhaustion, dehydration and heat-related complications, particularly among older adults, young children and people with existing medical conditions. Hospitals are also facing operational challenges as ageing buildings struggle to remain cool during prolonged periods of extreme heat.

The government is encouraging NHS organisations to strengthen heat resilience, including improved cooling systems, better emergency planning and greater public awareness campaigns to help reduce preventable illnesses during future heatwaves. Medical leaders say preparing for summer health pressures is now as important as planning for winter flu and respiratory diseases.

Experts believe climate-related health risks will continue to grow over the coming years, making investment in hospital infrastructure and community healthcare increasingly important. Public health teams are also urging people to stay hydrated, avoid prolonged exposure to high temperatures and regularly check on vulnerable relatives and neighbours during hot weather.

Healthcare specialists say adapting the NHS to a changing climate will be essential to protecting patients and maintaining high-quality care, as Britain experiences more frequent and intense periods of extreme summer weather.
