What is the normal temperature range measured orally?

The normal oral temperature range is most commonly established between 97.6°F and 99.6°F. This range reflects the average body temperature for healthy individuals and takes into account individual variations, including factors like the time of day, level of activity, and individual metabolism.

While the often-cited average body temperature is 98.6°F, it is important to understand that "normal" is not a one-size-fits-all number but rather a range. Measurements can slightly vary based on various circumstances; thus, this range accounts for those differences, allowing for a healthy variation in what one might expect when assessing body temperature.

Other options provided may have inaccuracies in the upper or lower limits that do not align with the consensus on normal oral body temperature, thus making this specific range the most widely accepted.
