Vigorous exercise in high ambient temperatures places the young athlete at risk from temperature changes due to dehydration. The three syndromes caused by exposure to high temperatures are: cramps, heat exhaustion and heat stroke.
Heat stroke is a severe disease that needs immediate treatment specialist, since it is accompanied by a high mortality rate. Initial treatment consists of removing the child from exposure to sunlight and to initiate external cooling maneuvers while moving the patient to a hospital.
The prevention of these disorders is focused on changing physical activity when there are potentially dangerous environmental conditions, with maintenance of adequate hydration, use of appropriate clothing and enough to heat acclimation. In the majority of young athletes, the water is still the ideal drink to restore the lost.
