The victim should be watched for further problems. Heatstroke is a life-threatening situation. Body temperature above 105 F, irritability, staggering, unconsciousness or convulsions, and lack of sweating are the common symptoms. Immediate efforts must be made to cool the victim to 103 F and move to a hospital immediately. Keep the head elevated.
Heatstroke occurs when the body's central control mechanisms fail.
Because of this general failure, the entire body can be damaged. Especially severe can be the damage to blood-clotting, liver and kidney functions. A survivor may have permanent damage to these organs, and may also be unable to bear heat as well as in the past. Healthy people get used to working in a hot environment within 2-3 days. The complete change takes place within 7-10 days.
