[37] [38] Normal daily temperature variation has been described as 0.5 °C (0.9 °F). [7]: 4012 A raised temperature is not always a fever. [37] For example, the temperature rises in healthy people when they exercise, but this is not considered a fever, as the set point is normal. [37]
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.
In humans, hyperthermia is defined as a temperature greater than 37.5–38.3 °C (99.5–100.9 °F), depending on the reference used, that occurs without a change in the body's temperature set point. [3] [10] The normal human body temperature can be as high as 37.7 °C (99.9 °F) in the late afternoon. [2]
The thermally neutral air temperature for an unprotected resting human is about 28 °C (82 °F), and the thermally neutral temperature in water is about 35 °C (95 °F), much closer to normal body temperature. This difference is due to the very different physical properties of the media.
Satisfaction with the thermal environment is important because thermal conditions are potentially life-threatening for humans if the core body temperature reaches conditions of hyperthermia, above 37.5–38.3 °C (99.5–100.9 °F), [11] [12] or hypothermia, below 35.0 °C (95.0 °F). [13]
In Europe, epinephrine is not recommended until the person's core temperature reaches 30 °C (86 °F), while the American Heart Association recommends up to three doses of epinephrine before a core temperature of 30 °C (86 °F) is reached. [2] Once a temperature of 30 °C (86 °F) has been reached, normal ACLS protocols should be followed. [50]
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 ...
Hay fever is not a true fever, meaning it does not cause a core body temperature in the fever over 37.5–38.3 °C (99.5–100.9 °F). [ citation needed ] Cause
