The normal human body temperature is generally accepted as around 98.6°F (37°C). However, it can vary between about 97°F (36.1°C) and 99°F (37.2°C) or slightly more depending on the individual and conditions
. More specifically, the typical normal range is often stated as 36.5–37.5°C (97.7–99.5°F)
. This range can differ based on factors such as:
- The method of measurement (oral, rectal, tympanic, axillary)
- Time of day (lowest in early morning, highest in late afternoon/evening)
- Age, sex, activity level, health status, and emotions
For example, average oral temperature is about 36.8°C (98.2°F), rectal or vaginal temperature is slightly higher around 37°C (98.6°F), and underarm (axillary) temperature is slightly lower around 36.5°C (97.7°F)
. In summary, normal body temperature varies but typically lies within the range of approximately 97°F to 99.5°F (36.1°C to 37.5°C), with 98.6°F (37°C) as the widely recognized average baseline
