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.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling.

Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
