Temperatures Expected To Peak At 46c As Europe Heatwave Continues
Heat exhaustion occurs when your body becomes too hot and struggles to regulate your core temperature.
It can affect anyone, including fit and healthy people - especially if they are doing strenuous exercise in high temperatures or have been drinking alcohol in the sun.
Heat exhaustion can come on very quickly, over a matter of minutes, or gradually, over a few hours. The symptoms you feel are your body's way of warning you to cool down, fast.
