Actually, a heat wave is no joking matter. Under normal circumstances, a person s body temperature is kept under control by perspiration and evaporation on the skin. When this system breaks down or is overwhelmed, a wide range of symptoms can occur, starting with heat cramps . Liquids with caffeine in them can cause further dehydration and can make the situation worse. In addition to an elevated body temperature, an affected person might experience a rapid heartbeat, feel lightheaded, nauseated, and cold and clammy to the touch, and suddenly become pale.
Prompt response is mandatory to prevent heatstroke.
The important thing is to bring down the body temperature as fast as possible. Get the person to a cool area at once, lay them down after loosening their clothing, apply a cool cloth to their face, neck and wrists, and elevate their legs. They should begin to feel better with their temperature coming down within a half hour. If a heat victim does not respond to preliminary first aid efforts, get emergency help immediately. If their temperature climbs to 105 F, and their skin becomes hot and dry time is really of the essence.
