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

The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
