What is the normal body temperature of a human?

The normal body temperature of a human is commonly cited as 98.6°F, which serves as a reference point for assessing an individual's health. This average value is derived from a range of temperatures that can vary between individuals, typically from 97°F to 99°F, depending on factors like the time of day, the individual's activity level, and the method of measurement (oral, rectal, or axillary).

The significance of 98.6°F lies in its historical context, as it was established by Dr. Carl Reinhold August Wunderlich in the 19th century, and has since been widely accepted in medical practice. Understanding this standard is crucial for monitoring health, as deviations from this normal range may indicate fever or hypothermia, prompting further investigation or intervention.

While other temperatures listed may be considered normal under specific circumstances or for certain individuals, the established average is most commonly recognized as 98.6°F in clinical settings.
