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.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature.
