Yes, the Oura Ring track your sleep as well as indicates your sleep stages like – light sleep, deep sleep, and REM sleep. Curious to learn more about the Oura Ring tracking your sleep? Let’s go through the article. 

Does Oura Ring Track Your Sleep?

Yes, Oura Ring tracks sleep accurately.

Oura Ring is designed to prioritize sleep tracking in addition to tracking other activities. It is proven that the Oura Ring can offer you research-quality data when it comes to sleep tracking. Sleep tracking data collected by Oura Ring could be validated by the standard polysomnography (PSG). Oura Ring developers designed the device to maximize sleep data quality.

Does The Oura Ring Accurately Track When You Fall Asleep?

Yes, as validated by the polysomnography (PSG) test in the laboratory, Oura Ring can accurately track when you fall asleep. 

If your Oura Ring has sufficient battery backup [minimum 20%], then the device will track your all health parameters during your sleep along with sleep insight. Oura Ring track your sleep in real-time, and you can find the data reflected in a graph in your Oura Ring app [on the paired smartphone]. 

How Does The Oura Ring Track Your Sleep?

Oura Ring track your sleep accurately by studying the biosignals, such as muscle movement, respiratory rate, heart rate, and body temperature. Oura Ring studies all the necessary parameters and determines when you fall asleep. After that, your data is analyzed and divided into 5-minute intervals. 

Based on the collected data, Oura breaks down your sleeping insights into four different stages. These four sleeping stages are – NREM 1, NREM 2, NREM 3, and REM. In other words, data is divided into – awake, light, deep, and REM stages. 

Let’s explore these sleeping stages in detail;

1. NREM 1:

The first stage is – non-rapid eye movement (NREM) sleep. This is a short phase where your heartbeat and breathing rates begin to slow down. This stage may last 5 minutes before you start entering into NREM 2.

2. NREM 2:

NERM 2 is the light sleep stage. It is ‘light’ but more intense than the NREM 1. At this stage, your heart rate decreases steadily. Breathing rate and body temperature also start decreasing. You can find it as the ‘the longest stage’ in your sleeping insight graph.

3. NREM 3:

This is known as the deep sleep or slow-wave sleep. Heart rate and breathing rate decrease at the same time. Skin temperature will be maximum at this point. 

4. REM:

This fourth stage is completely different from the previous three stages. During REM sleep, your heart rate, blood pressure, and even breathing rate will reach the highest peak! This is when you are dreaming, and your body remains completely immobilized. 

Considering all the changes in your body during sleep, Oura Ring track your sleep and accurately reflects the current sleeping stage. The first two stages we described are usually merged as ‘light sleep’, and the other two stages are prominently known as Deep Sleep and REM. 

Based on all the metrics, Oura Ring also generates your ‘Sleep score’ using a 100-point scale. 

How Does Oura Know When You Are Asleep? 

Oura Ring track your sleep smartly and knows when you are asleep. By ‘smartly’, we mean studying your body parameters smartly!

Unlike other smart rings and smart wearables, Oura Rings are dedicated to mapping sleep insights accurately. To do the job, this smart tracking device follows biosignals like – body temperature, heart rate, and respiratory rate. 

When you start falling asleep, all these parameters go through dramatic changes. For instance, your body temperature will be decreased, as well as your blood pressure and breathing rate. 

Moreover, the Oura Ring uses an accelerometer to read your movements and detect whether your body is at the complete resting position or not. This is why if you are turning over in bed or twitching in a nightmare, Oura can read the subtlest movements and reflect in the sleeping insights. 


Let’s measure your sleep insights accurately with an Oura Ring. All you need to do is wear this smart ring while sleeping and make sure that the device has enough power to record your sleep insights. Oura Ring track your sleep, and the accuracy of your sleeping data could be validated with polysomnography (PSG)! Let’s try Oura Ring and share your feedback.
