Your ScanWatch Light lets you track your sleep without requiring any action on your part. All you have to do is wear your watch to sleep: it will do the rest on its own.

If you do not want to track your sleep, remove your ScanWatch Light before going to sleep.

Retrieving your Sleep Data

You can retrieve the sleep data collected by your ScanWatch Light in the Home screen or in the Dashboard view of the Withings App.

• Grey or gap: time spent awake
• Medium blue: duration of light sleep
• Dark blue: duration of deep sleep

Important notes:

• We have chosen to disable the detection of naps to focus on an improved tracking of your nights. As the sleep function requires at least three hours of sleep in order to track data, sleep periods of less than three hours are not currently tracked.
• ScanWatch Light detects sleep according to several criteria. Some criteria correspond to both rest and sleep phases. ScanWatch Light sometimes interprets a rest phase as a sleep phase because the watch is almost motionless. Reading a book, for example, comes very close to the watch's sleep detection criteria. If the sleep duration calculated by the watch is not correct, you can edit your sleep data in the Withings App application.
• Sleeping while the watch is under pressure (e.g.: under one's pillow or head) this can lead to inaccurate measurements.
