The area of the eye closest to the nose is the measurably hottest spot on the face. Heat flows from higher to lower temperature, so the human skin will not drop below that of surrounding air, regardless of wind. The flow of energy to and from the skin determines our sense of hot and cold. The normal temperature of skin is about 33 ☌ or 91 ☏. A core temperature over 100.4☏ (38☌) is defined by medical experts as a fever caused by an infection or illness. A healthy person’s body temperature fluctuates throughout the day, being cooler in the morning and warmer in the afternoon. Recent studies have shown that the “normal” body temperature can have a wide range, from 97☏ (36.1☌) to 99☏ (37.2☌). The average normal body temperature is generally accepted as 98.6☏ (37☌).

Temperature controls our quality of life and the measurement of different types of temperatures are inter-related, especially when utilizing infrared thermal imaging for human temperature screening. The temperature of two systems is the same when the systems are in thermal equilibrium. Defined: The degree or intensity of heat or cold, with reference to some standard value.
