Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration.
