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 physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
