Nighttime Sleep Tracking

Oura Ring

Oura Ring

Oura Ring is specially engineered as a sleep-tracking device, providing accurate insights into nighttime sleep patterns. The ring has been validated against "the gold standard sleep laboratory test: polysomnography (PSG)", so we can be ensured that the sleep data it provides is highly accurate and reliable.

Its placement as a ring on the finger also gives it an advantage over other wrist-based wearables in terms of precision, allowing it to better capture your slightest movements and distinguish between minor and major movements, like twitching, turning, or getting up for a bathroom break.

#1 Detailed Sleep Analysis

Oura Ring

Oura Ring takes a holistic approach to analyzing sleep. It measures 7 aspects to provide a comprehensive understanding of your sleep quality, including total sleep, timing, efficiency, restfulness, REM sleep, deep sleep, and latency.

Total Sleep measures the total duration of your sleep compared to the recommended sleep time for your age. Meanwhile, Timing relates to circadian rhythm, indicating optimal sleep if you fall asleep and wake up with the fall and rise of the sun.

Efficiency is the percentage of time you actually fell asleep after going to bed, while Restfulness gauges how uninterrupted and sound your sleep was, factoring in disturbances such as wake-ups, excessive movement, and getting out of bed.

REM Sleep and Deep Sleep both indicate the amount of restorative sleep you get in each sleep stage, while Latency measures how long it takes for you to fall asleep.

#2 Sleep Score

Based on the 7 aspects mentioned, Oura Ring calculates a Sleep Score. Sleep Score is a comprehensive view of your overall sleep quality, ranging from 0 to 100. The optimal score is between 85 to 100, indicating excellent sleep quality.

If your sleep score if under 70, you may want to look into adjusting your sleep habits, such as establishing a consistent sleep schedule, creating a soothing bedtime routine, and limiting exposure to blue light before bed. You can also look for contributors that are red to identify which area of your sleep needs the most improvement.

Nighttime Biosignals Monitoring

Using 15 advanced sensors integrated into the ring, Oura continuously tracks your body's key biometric signals during sleep, including heart rate, skin temperature, and blood oxygen levels.

#1 Heart Rate

Oura Ring

Oura Ring

During nighttime, Oura Ring measures resting heart rate (RHR), which is the number of heartbeats per minute while the body is at rest. It is a key indicator of cardiovascular health, and can provide insights into your sleep quality. Some heart rate metrics you can view include average heart rate, lowest heart rate, and heart rate values every 10 minutes throughout the night.

Oura Ring also measures heart rate variability (HRV) while you sleep on a five-minute basis, using a popular HRV parameter known as rMSSD. HRV is the variation in the time interval between heartbeats, which reflects the body's ability to adapt to stress and environmental changes. A higher HRV indicates better cardiovascular health and recovery, while a lower HRV can signal increased stress or fatigue.

By getting informed about these metrics, you can better understand your body's physiological state and make adjustments to improve your sleep, health, and well-being.

#2 Skin Temperature

From the skin of your finger, Oura Ring can measure your body temperature throughout the night. Body temperature is one of the key indicators of overall health and well-being, as well as of sleep patterns. Oura Ring takes skin temperature data to understand when you fall asleep at night, wake up in the morning, or transition through different sleep stages.

#3 Blood Oxygen

Oura Ring

Oura Ring

Blood oxygen saturation levels (SpO2) indicate the amount of oxygen being carried in the blood, which is important for ensuring that organs and tissues receive an adequate oxygen supply for optimal functioning.

Not only that it measures the average blood oxygen, Oura Ring also tracks changes in your blood oxygen levels (SpO2) throughout the night, providing insights into your respiratory health and sleep quality.

Significant fluctuations in overnight blood oxygen levels can signal potential health challenges, like illness or breathing issues. Awareness of these SpO2 patterns can help you identify potential sleep disorders and take proactive steps to address them.
