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.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation.
