Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air.
