Any sleep graph can be further edited. You can rate the sleep, add additional awake periods, cut excess time, and add tags or comments.
The SleepScore charts are explained in details here:
The clock icon = sleep duration
The moon icon = deep sleep
The graph icon = regularity
The open eye = awake
The HR icon = heart rate
Hi @Jhorvin_David, red sections represent the period, where the app does not have data from the movement sensor. Either the whole app had to resume (usually due to some system “optimization”), or the access to the sensor was lost. If you are using a wearable, the watch could have been temporarily disconnected.
