Hot weather can severely impact vulnerable groups, including older adults and infants. The body maintains a core temperature of about 37C but struggles during heatwaves. Experts recommend ways to stay cool, such as closing curtains, staying hydrated, and avoiding sun exposure during peak hours. Those experiencing heat exhaustion should be moved to a cool area, provided water, and have their skin cooled. Additionally, precautions should be taken when swimming in open water, especially regarding hidden dangers and local warnings.
As the weather gets hotter, it is harder for the body to keep its core temperature down. The body opens more blood vessels near the skin to lose heat.
The UK Health Security Agency (UKHSA) recommends looking out for those who may struggle to keep cool, such as older people and those with underlying conditions.
Other advice for keeping cool includes staying indoors with closed curtains, drinking plenty of fluids, and avoiding exercise during the hottest parts of the day.
If someone shows signs of heat exhaustion, it is essential to move them to a cool place and help them rehydrate, while also cooling their skin.
