We normally regulate our body temperature by sweating. But some things can limit our sweat response during extreme conditions. High humidity, age, obesity, fever, dehydration, disease, and drug and alcohol use all limit our ability to sweat.

To protect your health when temperatures use these strategies:

Drink Fluids
During heavy exercise in a hot weather drink 16-32 ounces of cool fluids per hour.

Replace Salt and Minerals
Sweat leeches salt and minerals from the body. The easiest way to replace these are with foods or sports drinks.

Wear Appropriate Clothing / Sunscreen
Choose lightweight, light-colored, loose-fitting clothing. In the hot sun, a hat and sunscreen is helpful. Sunburn decreases your ability to cool yourself and causes fluids loss. Use sunblock with SPF 15 or higher.

Acclimate
You will have a greater tolerance if you become accustomed to the heat slowly If traveling to a hotter climate, allow several days to become acclimated before vigorous exercise, and work up to it gradually.

Use Common Sense
Avoid hot foods and heavy meals-they add heat to your body. Limit sun exposure during the mid-day hours.
