How Do I Join the New Sleep Staging Beta?
The Beta is now live for all Oura Gen3 members. The new sleep staging Beta is not available to Gen2 users because the new sleep staging algorithm was developed for the Gen3 ring, which has upgraded memory and additional sensors that enable it to power this more sensitive sleep staging algorithm. If you’re in the Beta, feel free to let us know your feedback here.
How Do I View My Sleep Staging Data?
Tap on the Sleep tab in the Oura App. During the Beta, the toggle above your sleep staging graph gives you the option to see your hypnogram using either the current algorithm (displayed with a black background) or the new sleep staging algorithm (displayed with a blue background).
Select the icon next to the toggle for more information on specific changes to each stage of your sleep, and to view side-by-side comparisons of your data from the night before.
Why Are My Sleep Score and Sleep Contributors Not Updated?
We are working directly with members to fine-tune how we translate the new sleep staging results into guidance like your Sleep Score, contributors, and insights messages within the app. During the Beta, the new sleep staging algorithm does not impact your Scores, contributors, and related insights messages. You can see both sleep staging algorithms in your Sleep tab by using the "New Sleep Staging Beta" toggle switch located above your sleep stage hypnogram.
Why Has My Deep/REM/Light Sleep Changed?
With the added sensitivity of the new sleep staging algorithm, you can expect to see changes to the amount of time spent in each sleep stage. While these changes may take time to adjust to, our hope is that delivering this added accuracy is the most valuable update we can make for our members.
Here are the changes you can expect below or read more about the patterns the ring looks for in each sleep phase. While a lot of factors determine the magnitude of changes you’ll see in your data, HRV has a large impact and can make it easier to predict what you’ll see in your own data based on whether you have higher, average, or lower HRV.
- Members with higher HRV: Large decrease in Deep, large increase in Light, small increase in REM, and little or no change in awake
- Members with average HRV: Large decrease in Deep, large increase in Light, small decrease in REM, and little or no change in awake
- Members with lower HRV: Large decrease in REM, large increase in Light, small decrease in Deep, and small increase in awake
How Accurate Is the New Algorithm?
During the Beta, you’ll be able to see both the current algorithm (displayed with a black background) and the new sleep staging algorithm (displayed with a blue background).
Oura's current algorithm was validated against the gold-standard sleep laboratory test, polysomnography (PSG), and matches performance with other commercial wearables. As science and technology advances, however, we’re capable of delivering more accurate hardware and algorithms. Oura's newest, upgraded sleep staging algorithm represents a leap forward in wearable sleep staging accuracy, achieving 79% agreement with PSG. Both algorithms uphold high accuracy standards that Oura has set for itself.
You can read more about our peer-reviewed validation on the blog as well as details about how the algorithm was developed on one of the largest global datasets to date, including a diverse range of sleeping patterns, physiology, and more.
