Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. In the presence of elevated relative humidity, the evaporation rate decreases.
