We spend roughly a third of our lives asleep, but simply knowing how many hours you were in bed doesn’t tell the whole story. Your sleep patterns, overnight heart rate, movement, and other signals can help build a much clearer picture of how well you’re actually resting.
The Zen Ring brings these insights together, helping you understand your nights and spot patterns over time.
Start With Your Sleep Score
Your Sleep Score gives you a simple overview of your night without having to interpret every individual metric.
It considers signals such as your total sleep, sleep patterns, movement, heart rate and heart rate variability (HRV) to provide a personalized daily score.
Rather than focusing too much on a single night, look at how your score changes over time. You may start noticing connections between your sleep and things like late nights, exercise, stress, travel or changes to your routine.
Understand Your Sleep Stages
Sleep isn't one continuous state. Throughout the night, your body moves between different stages, including light, deep and REM sleep.
Light sleep makes up a significant portion of the night and acts as a transition between different sleep stages.
Deep sleep is generally associated with physical restoration and recovery, while REM sleep is particularly important for processes involving memory, learning and emotional processing.
Your Zen Ring estimates how much time you spend in each stage, allowing you to explore your nightly sleep patterns and how they change over time.
Track Blood Oxygen While You Sleep
Blood oxygen sensing provides another piece of your overnight picture.
The Zen Ring tracks blood oxygen levels during sleep, allowing you to see trends and variations throughout the night.
As with other wearable measurements, this information is most useful for understanding patterns over time rather than interpreting an individual reading as a medical result.
Find a Bedtime That Works for You
Getting enough sleep isn't only about duration. Consistency matters too.
Bedtime Guidance uses your sleep patterns to help you understand when it may be a good time to start winding down for the night.
Over time, maintaining a more consistent sleep and wake schedule can help establish a healthier sleep routine.
Look at the Bigger Picture
The real value of sleep tracking isn't chasing a perfect score every morning.
It's learning what works for you.
Maybe you sleep better on days you're more active. Perhaps late meals affect your nights. Maybe your sleep changes during particularly busy weeks.
By looking at your Sleep Score, sleep stages, blood oxygen trends and bedtime patterns together, you can start connecting the dots between your daily habits and your nights.
Better sleep starts with understanding your own patterns.
