Heat stroke is an emergency condition where the body's core temperature is
markedly elevated (depending on the definition, about 104 F [40 C] or
above) after being exposed to high environmental temperatures combined with
neurologic symptoms and loss of body thermal auto regulation (ability of the
brain to control the body temperature). The
elderly and young children are at

Heat Stroke Causes
The major cause of heat stroke is prolonged exposure to high temperatures
and/or doing strenuous activity in hot weather.
Dehydration, drinking alcohol, side effects of certain medications, and wearing excess and tight clothing
