How to monitor daytime breathing disturbances with Apple Watch?

I can’t find any information on this. All literature that I’ve come across says that the Sleep Apnea Detection/Notification feature on Apple Watch records breathing disturbances at night. I work night shifts and sleep during the day. Will this still work under those conditions, because I’ve tried for a few days and it’s been hit and miss. I believe it’s set up correctly, and my watch is the same fit each time I sleep.
