Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
