Hello Adrian, from the wearable sensors, only movement and HR are used for additional awake detection.
If you have troubles with awake detection sensitivity, go to Settings → Sleep tracking → Awake detection, where you can fine-tune the sensitivity of each awake category. The default values are chosen to work in most environments, but in some cases, some adjustments are needed. This depends on the awake-like events the app can detect from your environment.

Here in the docs, you can check the dimensions the app uses for each sensitivity level.
