Smart Coaching - Polar Electro M400 User Manual

Sleep information at Flow web service and Flow app
M400 will track your sleep time and quality (restful or restless), if you wear it at night. You don't have to turn
the sleep mode on, the device automatically detects from your wrist movements that you're sleeping. Sleep
time, and its quality (restful or restless) is shown at the Flow web service and Flow app after M400 is synced.
Your sleep time is the longest continuous rest time that takes place within 24 hours starting from 18:00/6pm to
next day's 18:00/6pm. Breaks shorter than one hour in your sleep don't stop sleep tracking, but they are not
taken into account in the sleep time. Breaks longer than one hour stop sleep time tracking.
The periods when you sleep peacefully and don't move a lot are calculated as restful sleep. The periods when
you move and change your position are calculated as restless sleep. Instead of simply summing up all the
immobile periods, the algorithm gives more weight to long than short immobile periods. The percentage of rest-
ful sleep compares the time you slept restfully with the total sleeping time. Restful sleep is highly individual
and should be interpreted together with sleep time.
Knowing the amount of restful and restless sleep gives you a look into how you sleep at night and if it's
affected by any changes in your daily life. This may help you in finding ways to improve your sleep and feel
well rested during the day.
Activity data in Flow App and Flow web service
With the Polar Flow mobile app you can follow and analyze your activity data on the go and have your data
synced wirelessly from your M400 to the Polar Flow service. The Flow web service gives you the most
detailed insight into your activity information.
