What is the average temperature of the human body?

The average temperature of the human body is widely accepted as 98.6 degrees Fahrenheit. This figure, established by Carl Wunderlich in the 19th century, is recognized as the standard baseline temperature for a healthy adult. It is important to note that normal body temperature can vary slightly between individuals and can also fluctuate based on factors such as time of day, age, activity level, and the method of measurement.

Understanding this reference point is crucial, as it serves as a guideline for medical professionals to assess health. A temperature significantly above or below this average may indicate the presence of an illness or other medical condition. While individual temperatures can fall within a range of approximately 97 to 100 degrees Fahrenheit, 98.6 degrees remains the commonly accepted baseline for healthy adults.
