In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
