Juveniles are regularly less conscious of the need to recuperate and rehydrate. Thirst is a tardy symptom of dehydration - hydration, especially during lengthy physical activities, should be maintained.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
