Acclimating to the heat

The risk of heat-related problems is greater within the first few days of activity in a hot environment. That's why it's best to take it easy at first, gradually increasing the amount of activity — and the amount of protective equipment — as the days pass. Young athletes might need up to two weeks to safely acclimate to the heat.

During hot and humid conditions, coaches are encouraged to:

• Require young athletes to drink plenty of fluids before practice and during regular beverage breaks — even if they aren't thirsty
• Make sure clothing is light colored, lightweight and loosefitting, or exposes as much of the skin as possible
• Limit activity at midday, when the temperature is hottest
• Decrease or stop practices or competitions if necessary, or move them indoors or to a shady area
• Ensure that fluid is available at all times
