Heat exhaustion

Heat exhaustion is one condition on the spectrum of raised body temperature derived from a heat illness. Other heat illnesses include heat cramps and heat stroke. Heat exhaustion is caused by the raising of a person's body temperature from either environmental conditions or by exertion. A raised internal body temperature can induce high amounts of perspiration out of the body. Which can lead to the loss of water, salt, and electrolytes.

Prevention of any heat-related illness includes drinking adequate fluids, avoiding exercise in hot weather, avoiding medications that can lead to heat exhaustion, and removing or loosening clothing.
