Dehydration and youth sports: Curb the risk
If you're sweltering in the stands at a youth sporting event, imagine what it's like for the athletes. Learn who's at risk of dehydration — and how to prevent it.By Mayo Clinic Staff
Anytime children or adolescents play sports or exercise in hot weather, they're at risk of heat-related illnesses. Understand how heat-related problems happen and what steps you can take to prevent them.
Risk factors for dehydration
Your child might be vulnerable to dehydration and other heat-related illnesses in a hot or humid environment if he or she:
- Wears clothing or protective gear that contributes to excessive heat retention
- Rarely exercises
- Is overweight or obese
- Is sick or had a recent illness, especially involving diarrhea, vomiting or a fever
- Is taking certain supplements or medications, such as cold medicine
- Has had a previous heat-related illness
- Has a chronic condition, such as diabetes
- Isn't well-rested
Acclimating to the heat
Heat-related problems are most likely within the first few days of practice 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
- Decrease or stop practices or competitions if necessary, or move them indoors or to a shady area
