Heat Exhaustion

Sweat is the body's way of cooling off. But if you're overheated for an extended period of time and don't replace the fluids you've lost, the internal systems that regulate temperature become overwhelmed and can't release the heat. If you become dehydrated, heat exhaustion can lead to potentially deadly heat stroke. Take immediate action if you feel dizzy, clammy, or nauseated. Get some place cool and drink lots of cool water. Find some sports drinks with electrolytes and take it easy.
