Compete in Heat: Know Kids’ Liquids and Limits

Kids need liquids before, during and after exerciseChildren sweat less than adults which makes it harder for them to cool off. But how much should they be drinking exactly?  It’s important to know, as kids are more susceptible to heat illness than adults when active in hot, humid conditions.

Even BEFORE they exercise, the U.S. Soccer Federation recommends checking your child’s urine – if the color is dark, apple-juice color, they need more fluid. Even slight dehydration can compromise performance and increase the risk for heat-related illness.

Here is a helpful guidelines adapted from the National Athletic Trainers’ Association:Liquids

1 Hour Before Activity:

Kids < 90 lbs. need 3-6 oz. of fluid

Kids > 90 lbs. 6-12 oz. of fluid

During activity, every 20 minutes:

Kids < 90 lbs. need 3-5 oz. of fluid

Kids > 90 lbs. need 6-9 oz. of fluid

After activity, to replace fluids lost through sweat:

Kids < 90 lbs. need up to 8 oz. of fluid, per 1/2 lb. lost

Kids > 90 lbs. need up to 12 oz. of fluid, per 1/2 lb. lost

This brings up the point made well by SafeKids Upstate: Weigh your children before and after practice to see if they’re drinking enough to replace the fluid they lost through sweat.

What is the best fluid for kids to drink during activity?  Some research shows that young athletes will drink 90% more of a sport drink compared to water, and therefore stay better hydrated. Also, fluids with salt (sodium chloride) such as sports drinks increase thirst and maintain voluntary fluid intake as well as replace sodium lost through sweat.
