Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat.
