The normal human body temperature is often stated as 36.5â37.5 Â°C (97.7â99.5 Â°F). In adults a review of the literature has found a wider range of 33.2â38.2 Â°C (91.8â100.8 Â°F) for normal temperatures, depending on the gender and location measured.ormal human body temperature varies slightly from person to person and by the time of day. Consequently, each type of measurement has a range of normal temperatures.
Average human body temperature. Body temperature changes throughout the day. It is the lowest in the early morning between 4 and 6 a.m., and the highest in the early evening between 6 and 8 p.m. Normal temperature is about 37Â°C or 98.6Â°F. However, it can be as low as 36.1Â°C (97Â°F) in the early morning to a high of 37.2Â°C (99Â°F) in the evening and still be considered normal.
