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.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth.
