When you wake up you can access your sleep details via the Nightly Recharge view. Navigate
to the Nightly Recharge view by swiping left or right from the watch face. Tap Sleep charge to
see more details. The sleep charge details view displays the following information:
1. Sleep score status graph
2. Sleep score (1-100) A score that summarizes your sleep time and sleep quality into a
single number.
3. Sleep charge = Sleep score compared to your usual level. Scale: much below usual –
below usual – usual – above usual – much above usual.
4. Sleep time tells you the total duration between when you fell asleep and when you
woke up.
5. Actual sleep (%) tells the time spent asleep between the time you fell asleep and when
you woke up. More specifically, it is your sleep time minus the interruptions. Only the
time you actually spend asleep is included in actual sleep.
6. Continuity (1-5) : Sleep continuity is a rating of how continuous your sleep time was.
Sleep continuity is evaluated on a scale from one to five: fragmented – fairly
fragmented – fairly continuous – continuous – very continuous.
7. Long interruptions (min) tells the time you spent awake during the interruptions longer
than one minute. During a normal night's sleep there are numerous short and long
interruptions when you actually awaken from your sleep. Whether you remember these
interruptions or not depends on their duration. The shorter ones we don’t usually
remember. The longer ones, for instance when one might get up for a sip of water, we
can remember. Interruptions are illustrated as yellow bars on your sleep timeline.
8. Sleep cycles : A normal sleeper typically goes through 4-5 sleep cycles over the course
of a night. This equals to a sleep time of approximately 8 hours.
9. REM sleep % : REM stands for rapid eye movement. REM sleep is also called
paradoxical sleep as your brain is active but your muscles are inactive to avoid acting
out dreams. Just as deep sleep restores your body, REM sleep restores your mind, and
enhances memory and learning.
10. Deep sleep % : Deep sleep is the stage of sleep in which it is hard to be awakened since
your body is less responsive to environmental stimuli. Most deep sleep occurs during
the first half of the night. This sleep stage restores your body and supports your
immune system. It also affects certain aspects of memory and learning. The stage of
deep sleep is also called slow wave sleep.
11. Light sleep % : Light sleep serves as a transition stage between wakefulness and the
deeper stages of sleep. You can be easily awoken from light sleep since your
responsiveness to the environmental stimuli remains quite high. Light sleep also
promotes mental and physical recovery, although REM and deep sleep are the most
important sleep stages in that regard.
Sleep data in the Flow app and web service
How you sleep is always individual — instead of comparing your sleep stats to others, follow your own long-term
sleeping patterns to get a full understanding of how you sleep. Sync your watch with the Flow app after waking up to
see your last night’s sleep data in Polar Flow. Follow your sleep on a daily and weekly basis in the Flow app, and see
how your sleeping habits and activity during the day affect your sleep.
Choose Sleep from the Flow app menu to see your sleep data. In the Sleep structure view you see how your sleep has
progressed through different sleep stages (light sleep, deep sleep and REM sleep) and any interruptions to your sleep.
Usually sleep cycles proceed from light sleep into deep sleep and then to REM sleep. Typically, a night's sleep
consists of 4 to 5 sleep cycles. This equals to approximately 8 hours of sleep. During a normal night's sleep there are
numerous short and long interruptions. The long interruptions are displayed with the tall orange bars in the sleep
structure graph.
