(Greek: heat, heating, heater, hot, warm)
The term heat is employed in ordinary language in different senses. Some scientists distinguish four principal applications of the term:
- Sensation of heat.
- Temperature, or degree of hotness.
- Quantity of thermal energy.
- Radiant heat, or energy of radiation.
A standard test of pain response involves applying heat to the skin, and most of us perceive pain when the skin reaches an average critical temperature of 113 degrees F (45 degrees C), and everyone, with the exception of people with serious sensory dysfunction, perceives pain before his or her skin reaches a temperature of 116.6 degrees F (47 degrees C).
Even though there are three to four times fewer heat receptors than cold receptors in the human skin, freezing cold and burning hot sensation are both experienced exactly the same. Indeed, at 140 degrees F (60 degrees C) both the cold and heat pain nerve endings are stimulated, and after a point, there is no reason to make fine distinctions—all the brain has to know is that it is very painful!
2. Absence or loss of heat-perception; insensibility to heat: As a result of nerve damage in her hand, Quincy had thermanesthesia and so she had to be very careful when working in the kitchen.
2. A heating medicine, a calefacient; medicines that cause heat.
2. The treatment of disease by heat, or specifically by thermal baths.
3. The scientific study of heat as a therapeutic agent.
Hans was sweating less than usual when he was climbing up the mountain which suggested that he was experiencing thermhypesthesia.
2. Of the nature of heat; thermal.
2. A severe and often fatal illness produced by exposure to excessively high temperatures; especially, when it is related to significant physical exertion.
It is usually experienced with elevated body temperature, lack of sweating, hot dry skin, and neurologic symptoms; including unconsciousness, paralysis, headache, vertigo, and/or confusion. In severe cases, very high fever, vascular collapse, and coma also develop.
