Heatstroke (Sunstroke)

Heatstroke is an extremely dangerous condition, typified by high body temperature (usually above 105 degrees Fahrenheit, or 40.5 degrees Celsius), hot and dry skin, and a rapid pulse. It is also possible for the athlete to be coming in and out of consciousness. The first responder should call 911 (hospitals are best equipped to deal with this life-threatening condition) and then do whatever possible to cool the athlete (fanning, cold water, sponge bath, loosening clothing, cold-water bath). Until the athlete returns to consciousness, do not give fluids.

Heatstroke is caused by a combination of several factors.
