Heat index values remain especially vital for babies and toddlers. 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.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. When there is an excess of moisture in the atmosphere, the efficiency of the evaporation process is lessened, leading to less efficient body cooling and a sensation of overheating. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
