Heat index values are quite important for babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
