Heat index values are highly important for children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
