And because of that, the Oura Ring doesn’t measure heart rate, HRV, or body temperature while you’re active.
As a result, any measurement of heart rate or HRV during movement with infrared is worse than a measurement with green light. Because infrared light has a longer wavelength, it can penetrate deeper into the skin, but the signal is also weaker, so it’s more easily dispersed by motion. However, although green wavelengths can withstand movement more easily, Dunn told me that green light is “more sensitive to components of the tissue.” For example, melanin absorbs green light more effectively than it does infrared light.
“You have a faster fluctuation in the signal ,” Jessilyn Dunn, the Duke University researcher studying the COVID-19 applications of wearable devices, told me, “and that faster fluctuation has a lesser chance of being attenuated by a substance that it’s flowing through.” In other words, shorter, green wavelengths produce a clearer signal and are more “robust” against movement. The Oura Ring, by contrast, uses infrared frequencies. Most fitness trackers (including the trackers we recommend) use green light beams to measure your pulse. But if you want to dive deep into your sleep and health data, the Oura Ring may give you some eye-opening insights into your body and well-being. Is it worth that investment? The Oura Ring isn’t a great fitness tracker, so if logging workouts is important to you, it probably isn’t a good fit. However, the ring costs $300 (or more, depending on the finish). And unlike the bulkier fitness trackers we tested, the Oura Ring felt light, compact, and stylish. The Oura Ring told me more about my body than any of the sleep trackers we’ve tested, and after a while I did become more conscious of my lifestyle choices (perhaps at times a little too conscious). And it also gives you concrete suggestions for improving your sleep based on that data. Another is its ability to show how those vital signs change when you sleep, meditate, and go about daily activity. But one of the key things setting the Oura Ring apart from those apps is its ability to track your heart rate and heart rate variability (HRV) with high precision. I’ve found it to be a cleverly designed and reasonably comfortable tool that provides fascinating (to me) data and performs near the level of our best sleep-tracking apps. I wore the Oura Ring continuously (save for a few charging sessions) for more than six months (and I have been using it off and on for nearly a year). But does it actually help promote a healthier lifestyle?

Though it’s primarily a sleep tracker, measuring time spent in each sleep stage, the ring also records your heart rate, heart rate variability, breathing rate, skin temperature, and several other metrics. In fact, it’s one of the best smart wearables on the market.The Oura Ring is a tiny titanium device that tracks a host of data and aims to provide a clearer picture of what’s happening inside your body. Plus, it offers 16 hours of battery life. Basically, it has multiple functions and is an excellent option when compared to other fitness wearables. You can also wear it during the day if desired or use it as a fitness tracker. The ring vibrates when your blood oxygen drops, prompting you to adjust for better sleep. For example, you can monitor your O2 level, heart rate, and movements. Wear it during the day to take advantage of other features. Designed to be worn comfortably for while sleeping or anytime, this ring monitors and records your health and offers sleep tracking.īeing able to take advantage of sleep tracking to monitor sleep quality can be a game changer when it comes to health tracking. We also left options like the Motiv Ring off due to low ratings. Keep in mind that some rings, like the Oura Ring, NFC Smart Ring or options that offer bone conduction technology, didn’t make our list due to not being offered on Amazon. From excellent battery life to body temperature monitoring to sleep duration, heart rate, calories burned, blood oxygen level and more, these products will have you looking stylish and functional. If you are looking for the best smart ring, look no further. We’ve sorted through them all to find the best smart rings. The smart ring market on Amazon is ripe with choices.
