How Does Oura Measure Body Temperature?

Oura measures your body temperature continuously, directly from the skin of your finger. Other wearables use outward-facing sensors to estimate your temperature based on the external environment or estimate it based on your heart rate.

Interpreting Your Body Temperature

Your body temperature will appear as a deviation from your baseline body temperature. If you notice significant spikes clearly out of your normal range (e.g., due to illness), you'll see a lowered Readiness Score.

The Readiness tab displays your average body temperature for the previous night relative to your baseline (e.g., it is +0.3 or -0.2 today compared to your average normal temperature). Normal fluctuation (positive or negative) is typically 0.5 °C (0.90 °F). Anything outside of that could be an indication that something is challenging your system.

Body Temperature Trends

You can view your body temperature Trends using two different views.

To access these, simply tap on the Readiness tab and select 'Body Temperature' in the quadrant above your Readiness Score.


The Daily view focuses on short-term temperature changes. It displays the same value you see in your Readiness tab for each night. This view is ideal for spotting when something is starting to tax your body so you can prioritize rest and recovery.

The Trend view is optimized to help you spot trends in your temperature over time. Each date displays a weighted average of how your body temperature varies from your baseline based on a three-day window. Days closer to the current date are weighted more heavily.
