The normal daily temperature variation is typically 0.5 °C (0.90 °F), but can be greater among people recovering from a fever. [15] An organism at optimum temperature is considered afebrile, meaning "without fever". [26] If temperature is raised, but the setpoint is not raised, then the result is hyperthermia.
Skin temperature is the temperature of the outermost surface of the body. Normal human skin temperature on the trunk of the body varies between 33.5 and 36.9 °C (92.3 and 98.4 °F), though the skin's temperature is lower over protruding parts, like the nose, and higher over muscles and active organs.

He is known for his measurement of mean normal human body temperature of 37 °C (98.6 °F), now known more accurately to be about 36.8 °C (98.2 °F). [ 1 ] Life and career
The average difference between oral and axillary temperatures of Indian children aged 6–12 was found to be only 0.1 °C (standard deviation 0.2 °C), [51] and the mean difference in Maltese children aged 4–14 between oral and axillary temperature was 0.56 °C, while the mean difference between rectal and axillary temperature for children ...
98.6 °F (37.0 °C) is not the normal or average temperature of the human body. That figure comes from an 1860 study, [296] but modern research shows that the average internal temperature is 36.4 °C (97.5 °F), with small fluctuations. [297] [298] [299] The cells in the human body are not outnumbered 10 to 1 by microorganisms. The 10 to 1 ...
The average gestation period is 38 weeks, but a normal pregnancy can vary by up to 37 days. [191] Embryonic development in the human covers the first eight weeks of development; at the beginning of the ninth week the embryo is termed a fetus. [192]
Anders Celsius's original thermometer used a reversed scale, with 100 as the freezing point and 0 as the boiling point of water.. In 1742, Swedish astronomer Anders Celsius (1701–1744) created a temperature scale that was the reverse of the scale now known as "Celsius": 0 represented the boiling point of water, while 100 represented the freezing point of water.

The thermometer tip must then be left in place until a reading can be derived, usually about 3 minutes for mercury thermometers and 1 minute for newer electronic types. It is important to remember that the normal human core temperature range measured with a rectal thermometer spans from 37.0 to 38.0 degrees Celsius.
