Circulate the air with fans. Electric fans do not cool the air, but they do help evaporate sweat, which cools the body. Wear lightweight and light-colored clothing. Light colors will reflect away some of the sun's energy. Drink plenty of water regularly and often.
Water is the safest liquid to drink during heat emergencies.
Avoid drinks with alcohol or caffeine. They can make you feel good briefly, but they make the heat's effects on your body worse. Drink plenty of fluids even if you do not feel thirsty. To replace the four to eight quarts of sweat that may be produced in hot weather, people require one half to one cup of water every 20 minutes. Eat small meals more often.
