Revision 147006264 of "98.6" on enwiki

The article about the healthy core body temperature in humans redirects here,for other uses,see [[98.6 (disambiguation)]]

In the [[United States]], '''98.6''' degrees [[Fahrenheit]] is widely believed to be the healthy core body temperature for an adult [[human]]. 
[[Image:1911 Animal heat.png|thumb|400 px|Diurnal variation in body temperature, (from the 1911 [[Encyclopædia Britannica Eleventh Edition]]) ranging from about 37.5 °C from 10 a.m. to 6 p.m., and falling to about 36.3 °C from 2 a.m. to 6 a.m.]]

This belief is based upon one [[Germany|German]] study by [[Carl Reinhold August Wunderlich]] which found the [[mean]] body temperature of the study subjects, when [[rounding|rounded]] to two [[significant digit]]s, to be 37 degrees [[Celsius]]. This is 98.6 degrees on the Fahrenheit scale.

In reality, the expected normal core body temperature for an adult is expected to lie within a range of possible values. Although the range varies by source, one commonly cited normal range is 36.4 to 37.1 °C (97.6 to 98.8 °F).

In [[Russia]] the figure 36.6 °C has achieved a similar status. According to the Russian pharmaceutical chain named 36.6, "36.6 is the ideal body temperature in [[Celsius|Centigrade]] for healthy adults and children"  (36.6 degrees Celsius equals 97.9 °F, which is within the human norm for [[thermoregulation]]).

==Pop culture==

*"'''98.6'''" is also the title of a [[1967]] hit single by "[[Keith (singer)|Keith]]" (birth name James Barry Keefer, now legally changed to Bazza Keefer).[http://www.keith986.com/keithbio.htm]

The song relates the feeling of being in love to the feeling of good health and thus to the number 98.6.
