Children frequently do not comprehend the need for rest and hydration. Thirst is an advanced stage of dehydration - staying hydrated, especially during extended physical exercises, is essential.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
