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.
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 ...
Sweating occurs when the ambient air temperature is above 35 °C (95 °F) [dubious – discuss] and the body fails to return to the normal internal temperature. [18] The evaporation of the sweat helps cool the blood beneath the skin. It is limited by the amount of water available in the body, which can cause dehydration. [5]
The precise history of rectal thermometry is largely unknown, but medical thermometers have long been made in a tube shape that fits into the anus. Medical literature shows the practice dating back to at least the 18th century, and it is probable that rectal thermometry was thought to be a safer alternative to oral temperature-taking, due to the use of mercury and other toxic chemicals in ...
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
Most of Northern European Russia and Siberia between the Scandinavian Peninsula and the Pacific Ocean has a subarctic climate, with extremely severe winters (Dfd, Dwd, Dsd) in the inner regions of Northeast Siberia (mostly the Sakha Republic) with the record low temperature of −67.8 °C or −90.0 °F), and more moderate (Dwc, Dfc, Dsc ...
