The hypnogram is a diagram obtained by the continuous recording of the electroencephalogram during sleep, making it possible to specify the sleep cycles during the night. You will also find data on your position, heart rate and respiratory rate.
Tap anywhere on the Night Card to discover your hypnogram.

The position pictogram
The position pictogram shows the position of your head in relation to the bed. The in-built accelerometer measures this every 5 minutes. If you move more than once during a 5 minutes window, the position you stayed in the longest will be represented.
Number of position changes
This shows how many times you changed position while you sleep. A "position change" corresponds to a change in head position (over 45 degress in your body's axis). This indicator allows you to assess how much you moved during the night.
