Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate.
