What is the average rectal temperature for adults?

The average rectal temperature for adults typically falls within the range of 37.0 to 38.1 degrees Celsius. Rectal temperature is often considered the most accurate method for measuring body temperature because it reflects the core body temperature. This range accounts for normal variations in temperature among adults due to factors such as the time of day, physical activity level, and individual differences. In clinical practice, a rectal temperature within this range supports the assessment of a patient’s health status and can help in diagnosing fevers or hypothermia.
