SLEEP PLUS STAGES™ SLEEP TRACKING
Sleep Plus Stages automatically tracks the amount and quality of your sleep and shows you how long you spent in each
sleep stage. It gathers your sleep time and sleep quality components into one easily glanceable value, sleep score. Sleep
score tells you how well you slept compared to the indicators of a good night's sleep based on the current sleep science.
Comparing the components of the sleep score to your own usual level help you recognize which aspects of your daily routine
may affect your sleep and may need adjusting. Nightly breakdowns of your sleep are available on your watch and in the Polar
Flow app. Long-term sleep data in the Polar Flow web service helps you analyze your sleep patterns in detail.
How to start tracking your sleep with Polar Sleep Plus Stages™
1. The first thing you need to do is set your preferred sleep time in the Polar Flow or on your watch. In the Flow app,
tap your profile, and choose Your preferred sleep time. Choose your preferred time and tap Done. Or sign into your
Flow account or create a new one at flow.polar.com, and choose Settings > Physical settings > Your preferred
sleep time. Set your preferred time and choose Save. Set your preferred sleep time on your watch from Settings >
Physical settings > Your preferred sleep time.
Sleep time preference is the amount of sleep you want to get each night. By default, it is set to the average
recommendation for your age group (eight hours for adults from 18 to 64 years). If you feel that eight hours of sleep
is too much or too little for you, we recommend you adjust your preferred sleep time to meet your individual needs.
By doing this, you'll get accurate feedback on how much sleep you got in comparison to your preferred sleep time.
2. Continuous heart rate tracking needs to be enabled for Sleep Plus Stages to function. To enable Continuous HR
tracking go to Settings > General Settings > Continuous HR tracking and select
