Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
