While you sleep, the sensors sample your pulse 250 times per second to track both the strength of your heartbeat and your heart rate variability. From this, Oura’s algorithms derive insights about your sleep quality – for instance, tracking when you are in stages of light, deep or REM (rapid eye movement) sleep.Jun 18, 2019
The company’s validation studies (PDF) have shown the Oura Ring’s measurements of heart rate and HRV to be 99.9% and 98.4% accurate, respectively, in comparison with an electrocardiogram. Those extra data points give the Oura Ring’s analyses more nuance compared with what most sleep trackers offer.
Sleep score ranges are: Excellent: 90-100. Good: 80-89. Fair: 60-79.
The Oura Ring sleep and activity tracker.
The $149 postage stamp-sized sensor attaches to the forehead using a hypoallergenic disposable adhesive, where it then measures the wearer’s blood oxygen (SpO2) level, heart rate, sleep position, movement, snoring, awakenings and any stopped breathing events overnight.
While the Oura Ring cannot be used to diagnose sleep apnea, it can provide helpful insights on the quality of your sleep. Individuals with sleep apnea may experience reduced deep and REM sleep, which may be reported as excessive awake time in the Oura app.
Now, with watchOS 8, you can also track your respiratory rate throughout the night, which could help to detect early signs of medical conditions like sleep apnea, and chronic lung disease, among others. Using its built-in accelerometer, the Apple Watch can track the number of breaths you take per minute while asleep.
More on Body Temperature: In addition to your score up top, body temperature is a contributor. When your body temperature is within a normal range, it boosts your Readiness Score. Body temperature readings significantly above or below your normal range will lower your score.
Scientists agree that sleep is essential to health, and while stages 1 to 4 and REM sleep are all important, deep sleep is the most essential of all for feeling rested and staying healthy.
The Infrared Photoplethysmography (PPG) Sensors
The PPG system sends light through LEDs and receives it with a photodiode that captures how pulses of light through your arteries reflect your heart’s activity. Oura samples 250 times per second and is 99.9% reliable compared to a medical-grade electrocardiogram (ECG).
In addition to blood pressure, the device monitors your activity level, sleep patterns, and calories burned.
From the gathered data, Oura’s activity algorithms are fine-tuned to recognize steps from the rest of your daily movement. Oura is able to identify step patterns within a very small window of time (30 seconds) and with a high level of precision from your finger.
No, Oura doesn’t track heart rate during exercise or other activities. The ring tracks your resting heart rate while you sleep, and during restful moments during the day.
With your profile information in mind (e.g., age, weight, height, and gender), Oura delivers personalized daily activity goals and a record of your overall activity levels and calorie burn. Here’s a quick breakdown: Goal Progress: “How many active calories have you burned today vs. your Oura goal?”
The Oura Ring is water-resistant up to 100 meters (~330 ft.). This means you can bathe, swim, dive, wash dishes, and do most anything with your ring that involves water.
There is no absolute requirement to wear your Apple Watch in bed with the AutoSleep app. If you do, it uses the Watch’s sensors to establish when you sleep and will then monitor movement and heart rate to provide a sleep score in the morning.
It is relatively safe to sleep with an Apple Watch on in the short term because the Electromagnetic Frequency (EMF) levels emitted by the device are relatively low. However, an EMF Harmonizer Watchband should be used to block the EMF radiation when using the watch every night.
Will Apple Watch call 911 if my heart rate is above 150? No, Apple Watch will not call anyone regardless of whatever your heart rate may be.
The Oura Ring is a wearable device that tracks your activity throughout the day and your recovery throughout the night. That means it takes into account how much effort you’ve expended during the day to be able to determine the amount of rest you need.
By using a 3D accelerometer, the Oura Ring is able to measure the movement of your hand to estimate whole-body activity (physical activity) and leg movement (step count). Your Activity Score ranges from 0-100. Scoring anywhere from 85-100 means you’ve achieved an optimal balance between activity and rest.
While sleep requirements vary slightly from person to person, most healthy adults need seven to nine hours of sleep per night to function at their best. Children and teens need even more. And despite the notion that our sleep needs decrease with age, most older people still need at least seven hours of sleep.
The root cause of sleep inertia is clear
Sleep inertia is the result of sudden awakening during REM sleep. When you wake up during REM, you still have high levels of melatonin, causing sleepiness. The longer you sleep, the higher level of melatonin is observed during REM stage.
Oura measures your body temperature to help analyze your recovery. … An individual’s body temperature typically changes by about 1 °C (1.8 °F) between its highest and lowest points each day.
In short, yes, you can wear your Oura Ring while doing most activities at the gym. To protect your finger and your Oura Ring, though, we don’t recommend wearing your ring while lifting weights. Like other jewelry, Oura Rings may become scratched if worn while lifting weights or gripping barbells or dumbells.
By wearing your Oura Ring 24/7, you allow Oura to personalize your data insights and overall experience to a maximum degree. By choosing to wear your ring only at night and not during the day, you may have a different experience than those who wear their ring 24/7.
Track your progress automatically with Fitbit, Apple HealthKit and Oura syncing. … LIFE Extend can now automatically sync with your Fitbit, Apple HealthKit (for iPhone/iPad users) and Oura data, making it even easier to track your progress.
When Oura detects an activity, it will show up at the top of your Home screen the next time you open your Oura App. For Automatic Activity Detection to kick in, you need to remain active for at least 10 minutes, so Oura can identify your movement as one session.
Some days the Fitbit is higher, and some days the Oura ring shows more steps, but they are usually within a reasonable range. As with any step tracker, it doesn’t matter the accuracy of the data as much as the work you put in to improve.
For most young people, highly trained athletes, and people who work out regularly, a low heart rate while exercising — defined as below 60 bpm — is normal and healthy. The same goes for your nightly snooze. When you’re asleep, your heart rate normally slows down to 40 to 60 beats a minute.
The Oura Ring does not send location information. However, if you’ve lost your ring and it has battery remaining, you can use the app Find My Bluetooth Device in an attempt to track it down. If you suspect your ring may have been stolen, there’s no need to worry about someone else accessing your data.
Lastly, the Oura Ring is durable and water-resistant. It is made from scratch-resistant, durable titanium with a diamond-like carbon coating. The Oura Ring is the perfect balance of durability and comfort. You will barely remember you are even wearing it.
According to Oura’s return policy, we allow only one return or exchange per original order. This means you can return your original ring once for a refund, or exchange it once for a size or color change. Size and color changes cannot be made after one exchange has already been completed.
