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 innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process.
