Although beer and alcoholic beverages appear to satisfy thirst, they actually cause further body dehydration. Dress in loose-fitting clothes that cover as much skin as possible. Lightweight, light-colored clothing reflects heat and sunlight and helps maintain normal body temperature. Protect face and head by wearing a wide-brimmed hat. Avoid too much sunshine.
Sunburn slows the skin's ability to cool itself.
Avoid extreme temperature changes. A cool shower immediately after coming in from hot temperatures can result in hypothermia, particularly for the elderly and very young.
