Heat injury and illness can range from simple muscle cramping to life threatening heat stroke. The most important issues in preventing heat related injury are to make sure the athlete is properly hydrated and limit activity when the heat and humidity are extremely high. Pre-hydrate with 17-20 oz. of fluids 2-3 hours prior to activity. Consume 7-10 oz. of fluids every 15-20 minutes during activity and rehydrate with 17-24 oz. of fluids for every pound lost during activity.
