Dress for the heat. Wear loose-fitting clothes that cover as much skin as possible. Lightweight, light-colored clothing that 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.
Drink FOR the Heat. Drink plenty of water and natural juices, even if you don't feel thirsty. Even under moderately strenuous outdoor activity, the rate your body can absorb fluids is less than the rate it loses water due to perspiration. Do not drink IN the Heat. Avoid alcoholic beverages and beverages with caffeine, such as coffee, tea, and cola.
