Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
