I am excited to share with you my latest systematic test of the Oura Ring 3. As many of you know, I think the Oura Ring has been one of the best health trackers for a while now, and I even showed in a recent video how it helped me track my COVID-19 infection. However, one area where the Oura Ring has fallen short is sleep stage tracking. But, Oura has recently introduced a new beta sleep stage algorithm that they claim will be a significant improvement. In this video, we will be taking a first quick look at this new algorithm and see if it lives up to the hype. Additionally, I will also be re-testing the workout heart rate feature that was introduced with the Oura Ring 3. In my original test I had some issues with this feature, and today I wanted to see if they made any improvements. I hope you are as excited as me to see how these new features stack up. Now, as you might know, after the release of the Oura Ring 3, Oura introduced a workout heart rate feature, which allows the Oura Ring to track your heart rate during 5 types of exercises. For now they only allow heart rate tracking during indoor and outdoor running, indoor and outdoor cycling and walking. So, to test this workout heart rate tracking feature I will compare the measurements of the Oura Ring 3 to an ECG chest strap from Polar called the H10. Now, the Polar H10 has been used in quite some scientific studies, and it was actually shown to be more reliable for heart rate tracking during medium intensity exercises than a professional scientific Holter ECG monitor. Next, for the sleep stage tracking I compared the sleep staging tracked by the Oura Ring 3 to an EEG device called the Dreem 2 that can actually measure my brainwaves, and has been shown to be relatively reliable at sleep stage tracking. It is not the gold standard in sleep stage tracking, but it should give us a good first impression of how the Oura Ring performs, and also how it compares to more than 40 other devices I tested over the last years.
