What is heat exhaustion?

Heat exhaustion is when your body overheats. Normally, the body has a cooling system that is controlled by the brain. The cooling system adjusts to hot conditions and lowers your body temperature by producing sweat. With heat exhaustion, the body's cooling system is not working well and results in an increased body temperature.
