Vital heat Vital heat, also called innate or natural heat, or ''calidum innatum'', is a term in Ancient Greek medicine and philosophy that has generally referred to the heat produced within the body, usually the heat produced by the heart and the circulatory system. Vital heat was a somewhat controversial subject because it was formerly believed that heat was acquired by an outside source such as the element of fire. ==Origin of concept==
It was a previously accepted concept that heat was absorbed through external sources, however the concept of vital heat was more or less stumbled upon by a physiological observation that associates cold with the dead and heat with the living. "For the concept of vital heat we may--somewhat arbitrarily-- take out starting point in Parmenides. His correlation of dead with cold, alive with warm, may not have been primarily intended as a contribution to physiology, yet the physiological significance of this thought was perceived by his successors; witness Empedocles, who taught 'sleep comes about when the heat of the blood is cooled to the proper degree, death when it becomes altogether cold'". Aristotle would eventually modify this doctrine stating that "sleep is a temporary overpowering of the inner heat by other factors in the body, death its final extinction."〔
