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.
The six components of the sleep score are grouped under three themes: amount (sleep time), solidity (long interruptions,
continuity and actual sleep) and regeneration (REM sleep and deep sleep). Each bar in the graph represents the score for
each component. Sleep score is the average of these scores. By choosing the weekly view you can see how your sleep
score and sleep quality (solidity and regeneration themes) vary during the week.
