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.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process.
