Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth.
