Heat Exhaustion – What To Do

As the summer gets into its stride, we thought we’d share the St John Ambulance’s advice on how to treat someone with heat exhaustion.

Heat exhaustion is caused by a loss of salt and water from the body, usually through excessive sweating. It develops slowly and usually happens to people who aren’t used to hot, humid weather. People who are unwell are more likely to get it, especially if they are suffering from vomiting and diarrhoea. A dangerous and common cause of heat exhaustion is when the body produces more heat than it can cope with.

This can happen when someone takes a non-prescription drug, like ecstasy, which can stop the body from regulating its temperature properly. If someone gets hot and sweats a lot from dancing as well, they may get overheated and dehydrated, giving them heat exhaustion. If treated quickly, someone suffering from heat exhaustion should start feeling better quickly. But if not treated, they could develop heatstroke which can lead to death.
