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.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
