Heat index values hold great significance to children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
