[Question] How good is the case for retraining yourself to sleep on your back?

I fre­quently hear the ad­vice that it’s bet­ter to sleep on the back and worth­while to learn to sleep on your back. Are there any stud­ies that backup that ad­vice. Other­wise are there other good ar­gu­ments? Per­sonal ex­pe­rience is also wel­come.

No answers.
