Has the Average Body Temperature Changed?

During the nearly 160 years covered by the analysis, the average oral temperature gradually fell by more than one degree. As a result, the "new normal" seems closer to 97.5˚ F. This observation held up even after accounting for age, gender, body size, and time of day.

What is the new average body temperature?

Normal Range

A German doctor in the 19th century set the standard at 98.6 F, but more recent studies say the baseline for most people is closer to 98.2 F. For a typical adult, body temperature can be anywhere from 97 F to 99 F. Babies and children have a little higher range: 97.9 F to 100.4 F.

How much does body temperature vary throughout the day?

Your Temperature Naturally Fluctuates

An individual's core body temperature typically changes by about 1 °C (1.8 °F) between its highest and lowest points each day. Anything outside of that range indicates that something is challenging your body and preventing it from adjusting.
