Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
