Helo devices are able to monitor your REM Sleep time, when the 24h monitoring feature is on. To activate your 24h monitoring on your device follow this tutorial, or the video below if you own a BioSense.

Once activated, log into your App and go to the “Data” page to click on the Sleep Analysis record. Your historical health data is stored in the App and is visible at any time using the calendar view.

Please note:
- Activating 24h monitoring can reduce the battery life of your device.
- The 24h monitoring and REM Sleep time feature require a Wellness+ subscription. 
- The result will be visible on the App only after 6 hours, as the watch will monitor and collect the atrial activity to set a baseline for more accurate results.
