Begin treatment by getting the person out of the heat and into a cooler place. Remove or loosen tight clothing and apply cool, wet cloths, such as towels or sheets. If the person is conscious, give cool water to drink, a half glass every fifteen minutes, and make sure the person drinks slowly. Again, do not give liquids that contain alcohol or caffeine. Let the victim rest in a comfortable position, and watch carefully for changes in his or her condition.
Heat stroke is the most serious heat emergency.
It is life threatening. The victim's temperature control system, which produces sweating to cool the body, stops working. The body temperature can rise so high that brain damage and death may result if the body is not cooled quickly. A person suffering from heat stroke needs help fast. Immerse the victim in a cool bath or wrap wet sheets around the body and fan it.
