Heat Stress in Exercising Children
- The intensity of activities that last 15 minutes or more should be reduced whenever high heat and humidity reach critical levels.
- At the beginning of a strenuous exercise program or after traveling to a warmer climate, the intensity and duration of exercise should be limited initially and then gradually increased during a period of 7 to 14 days to acclimatize to the heat, particularly if it is very humid.
- Before prolonged physical activity, children should be well-hydrated and should not feel thirsty. For the first hour of exercise, water alone can be used. Kids should have water or a sports drink always available and drink every 20 minutes while exercising in the heat. Excessively hot and humid environments, more prolonged and strenuous exercise, and copious sweating should be reasons for children to substantially increase their fluid intake. After an hour of exercise, children need to drink a carbohydrate-electrolyte beverage to replace electrolytes lost in sweat and provide carbohydrates for energy.
- Clothing should be light-colored and lightweight and limited to one layer of absorbent material to facilitate evaporation of sweat. Sweat-saturated shirts should be replaced by dry clothing.
- Practices and games played in the heat should be shortened and more frequent water/hydration breaks should be instituted. Children should seek cooler environments if they feel excessively hot or fatigue.
