Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process.

When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
