Young ones often do not realize the necessity to rest and replenish their fluids. Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate.
