Playing outside is a lot of fun, but it can become a challenge when the weather gets warm. A heat index at or above 90°F, as defined by the National Weather Service, can pose a significant health risk—especially for children.

Children who are playing sports or spending extended time outdoors—especially beyond 15 minutes—should take precautions to avoid dehydration and serious heat-related illnesses such as heat exhaustion or heat stroke.

Understanding Heat Risks for Kids

Young athletes are more vulnerable to heat-related illness because their bodies are still developing and may not regulate temperature as efficiently as adults. High temperatures combined with humidity can increase the likelihood of heat stress during physical activity.

Tips to Prevent Heat-Related Illness

Stay hydrated: Drink fluids frequently. Water is sufficient for the first hour of activity. For longer durations, consider sports drinks to replenish electrolytes.
Wear proper clothing: Choose light-colored, lightweight and breathable fabrics to allow sweat to evaporate efficiently.
Modify activity: Practices and games should be shortened in extreme heat, with frequent water breaks incorporated.
Acclimate gradually: When traveling to warmer or more humid climates, allow several days to adjust. Start with light activity and slowly increase intensity.

Warning Signs to Watch For

Seek medical attention immediately if your child experiences any of the following symptoms:

Faintness or extreme fatigue
Headache or fever
Unusual thirst or decreased urination
Nausea or vomiting
Muscle pain, spasms or tingling/numbness in the skin
