Heat Exhaustion AudioHealth Library Topic 1759 Heat Exhaustion Heat exhaustion happens when the body is exposed to extremely hot temperatures.
Heat exhaustion is related to heat stroke, although they are two separate problems.
In fact, a person can have heat exhaustion without developing heat stroke, and vice versa. However, heat exhaustion can develop into heat stroke, if left untreated. Heat exhaustion is caused by failing to replace fluids lost through perspiration and by generating more heat internally, through either work or exercise, than the body is capable of losing. Working or exercising in an extremely hot environment can be dangerous, especially for those not used to the heat. Other things that may lead to heat exhaustion include not having enough salt in your diet or not sweating enough to cool-down the body.
