Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
