Understanding Normal Body Temperature: Range, Fluctuations & Factors

A normal body temperature is typically defined as 97.6 to 99.6 degrees Fahrenheit (36.5 to 37.5 degrees Celsius), although it can vary slightly from person to person. Body temperature can fluctuate throughout the day, with the lowest temperature usually occurring in the early morning and the highest temperature in the late afternoon or early evening.

Factors such as physical activity, stress, environmental temperature, and certain medical conditions can affect body temperature. When exposed to extreme temperatures, such as hot or cold environments, the body will attempt to regulate its temperature to maintain a steady internal environment.
