The first step in treating heat stroke is to reduce body temperature by cooling the body from the outside. This can be done by removing tight or unnecessary clothing, spraying the person with water, blowing cool air on the person, or wrapping the person loosely in wet sheets. Alternatively, ice packs can be placed at the neck, groin and armpits to accelerate cooling.
