Once you’ve set up your Nokia Sleep, it lets you track your night heart rate without requiring any action on your part. All you have to do is lay in bed: it will do the rest on its own.
You can retrieve your night heart rate measurements collected by your Nokia Sleep in your Timeline or on your Dashboard in the Nokia Health Mate app.
Your average night heart rate is displayed at the bottom of your sleep graph. Tap on Heart Rate to see the details of your night.
Nokia Sleep is not a medical device and should not be used to diagnose, treat, cure, or prevent any medical conditions.
