Heat exhaustion follows an episode of dehydration, the body mechanism of regulating internal body temperature is impaired. However, it is not life-threatening. Exercise and hot weather conditions could also play a role in heat exhaustion.

Normally excess heat is gotten rid of the body through the pumping of blood to the skin surface, producing sweats, sweats as a cooling effect on the skin.

But If the body is in a state of dehydration, there is a deficit of water and essential electrolytes essential for the formation of sweats; hence sweats are not produced, and a form of heat exhaustion is experienced. Signs include: 

• weak rapid pulse
• excessive sweating
• increased internal body temperature
