Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
