Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. When there is abundant moisture in the air, the body's cooling through the evaporation process becomes less effective, leading to the sensation of overheating.
