Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth.
