Sleeping on your stomach is a habit. Will it strain your back?

I have a habit of sleeping face down.
Even though I sleep straight, I wake up in the morning lying face down. Is it because that position is comfortable?
I think it was seen in the past that lying down was bad for your health...
Is your back okay? My back hurts a little bit.
건강검진, 실제 효과 있을까?
