Heat index values hold particular significance for children. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
