How Accurate Is My Oura Temperature Data?

The Oura Ring measures body temperature using an advanced infrared sensor embedded in its inner surface called the Oura Ring temperature sensor. How accurate is my Oura temperature data? If you are asking this question yourself, we have a detailed article to explain everything you need to learn about this interesting topic. Let’s start!

How Does Oura Measure Temperature?

First things first. Let’s see how Oura measures the temperature so that you can understand the mechanism behind it. The Oura Ring measures temperature using an advanced infrared sensor located on the underside of your finger.

It comes to you with advanced Negative Temperature Coefficient (NTC) sensors to detect fluctuations in skin temperature. Unlike traditional thermometers that offer a single snapshot, the Oura Ring measures temperature every minute. 

This frequent temperature measurement is useful in more ways than one in order to understand the changes in both the internal body and outside temperature day and night.  Simply, you just cannot expect a traditional thermometer kept under your tongue to provide accurate readings as the Oura Ring does. 

What Temperature Does an Oura Ring Measure? Skin or Core?

The Oura Ring measures skin temperature rather than core temperature. Skin temperature is assessed from the underside of your finger and this figure can change significantly due to various factors such as the activities you do, stress, and environmental factors. 

This measurement is important as it tells how your body adjusts to internal and external changes.

However, the core temperature is often measured under the tongue by using a thermometer which tends to remain stable. Yes, core temperature readings are essential to detect health conditions like fever, but it doesn’t necessarily suggest that core temperature always tells you rapid fluctuations like skin temperature.

How Accurate Is My Oura Temperature Data?

If you are an Oura Ring user knowing whether the ring works how it should is important. 

Oura’s temperature sensor was validated against research-grade iButton sensors under controlled lab conditions. The results showed that Oura’s temperature measurements matched iButton performance with over 99% accuracy, with changes measured as precisely as 0.13°C (0.234°F).

In addition, in practical settings, Oura’s sensor maintained high accuracy, matching iButton performance with 92% accuracy. According to Oura, this validation was conducted with 16 individuals wearing both Oura Rings and iButtons in various real-life scenarios.

The most important thing is that Oura Ring has the ability to detect physiological temperature changes rather than environmental changes. This plays a pivotal role in the accuracy of Oura Ring temperature readings.

What Factors Can Affect the Accuracy of Oura Ring Temperature Readings?

There are several factors that contribute to the accuracy of Oura Ring temp readings. We have listed them for your observation.

The Fit

Proper skin contact is important for an Oura Ring to measure the temperature precisely. An Oura Ring that is too loose or too tight can affect the quality of the temperature data. Choosing an Oura Ring that fits nicely is not only important for temperature readings but overall functionality of the ring.

Environmental Conditions

Yes, as we described, Oura Ring is designed to reflect physiological changes rather than environmental temperatures. However, it doesn’t suggest that environmental conditions have no say when it comes to temperature readings of an Oura Ring. 

Extreme environmental conditions can still influence the skin temperature. For example, high humidity or exposure to direct sunlight can impact the skin temperature. So, when assessing the temperature, you should be aware of the surrounding conditions to get an accurate reading. 

Physical Activities

Intense physical activity can cause temporary increases in skin temperature. While the Oura Ring can track these changes, it’s essential to consider that transient spikes in temperature may not always reflect long-term physiological trends.

In addition, certain physical activities have the potential to change the position of the placement of the ring. This can also impact the temperature readings of an Oura Ring. 

Physiological Factors

Health conditions such as fever can significantly change the skin temperature. The Oura Ring does have the ability to detect these fluctuations but it is important to interpret properly when measuring the temperature. 

In addition to the above-mentioned factors, the placement of the ring, proper calibration, maintenance, and battery life also can influence the accuracy of Oura Ring temp readings.

How Can You Improve the Accuracy of Your Oura Ring Temperature Data?

Here are some best practices to get the most accurate temperature readings from your Oura Ring. 

• Make sure the ring fits snugly but comfortably on your finger.
• Wear the Oura Ring consistently on the same finger to maintain uniform data.
• Clean the ring regularly to remove any dirt or sweat that might interfere with the sensors.
• Try to avoid exposing the ring to extreme temperatures or humidity.
• Understand that health conditions like fever or hormonal changes can impact temperature readings.
• Try to keep your finger dry when wearing the Oura Ring.
• Ensure the Oura Ring is adequately charged always.
