Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature.

Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.
