How Smart Rings Track Sleep

Sensors and Technology

When you wear a smart ring, you might wonder how it knows so much about your sleep. The answer is in the tiny sensors packed inside. These sensors work together to collect data while you rest. Here’s a quick look at what you’ll find inside most smart rings:

The 3-axis accelerometer is one of the main sensors. It tracks how much you move during the night. If you toss and turn, the sensors pick it up. The optical heart rate sensor shines a light into your skin. It checks your pulse and helps the ring understand your sleep patterns. Some rings even add extra sensors for skin temperature or blood oxygen. These sensors make your ring smarter and more helpful.

Sleep Metrics

Smart rings use their sensors to measure many things about your sleep. They look at how long you sleep, how deep your sleep is, and if you wake up during the night. Here’s what you can expect:

The sensors help the ring figure out if you are in light, deep, or REM sleep. Some rings use sensors to check for signs of sleep apnea. You get a report in the morning that shows your sleep score, how much time you spent in each stage, and if you had any problems.

Tip: The more sensors a ring has, the more details you get about your sleep.

Data Accuracy

You might ask, “How accurate are these sensors?” Studies show that smart rings like the Oura Ring can tell if you are asleep or awake about 85% of the time. That’s pretty close to what doctors see in sleep labs. For sleep stages, the sensors do a good job, but they are not perfect. Sometimes, the sensors might miss small changes, especially for deep or REM sleep. Still, for most people, the sensors give enough information to help improve sleep tracking at home.
