Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
