Heart rate keeps turning off at night Charge 5

Why does my Fitbit 5 keep turning off my heart rate monitoring? I wear it for info about my sleep and there are huge gaps in my data.

Welcome to the Fitbit Community forums, @hannahevans.  

Thank you for sharing this information about the inconvenience you've been experiencing with your Charge 5. 

First we need to make sure that some of the basic troubleshooting steps have been exhausted. If you haven't done so already, please follow the instructions in this article to improve the accuracy of heart rate information by adjusting the position of the device and check the information mentioned here about other factors that could affect your heart rate reading, this has been useful to other users who have experienced something similar. 

In addition, I recommend that you try restarting the device using the three pulse restart method mentioned here below, instead of the restart option found on the Charge 5 itself: 

1. Connect your device to the charging cable. For instructions, see How do I charge my Fitbit device?
2. Press the button located on the flat end of the charger 3 times (end of the USB cable), pausing for 1 second between presses. Then wait 10 seconds or until the Fitbit logo appears.
