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.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat.
