My whole life I've been told that I shouldn't sleep on my tummy. I assumed that doctors knew best so I slept on my back and sides. A few times I went to sleep while my wife had her lamp on to read and I laid on my tummy to bury my eyes in my pillow. I noticed that when I slept on my tummy I awoke more rested than usual. The other thing I noticed was that when I slept on my back and side that I had to roll over several times in the night else I'd awaken with a back ache. When I sleep on my tummy I sleep in the same position all night and don't have a backache in the morning. Everyone I talk to acts like sleeping on your tummy is bad and undesirable but for me it works. I was buying a pillow and the clerk asked me if I was a back or side sleeper and I answered that I sleep on my tummy. He showed me a pillow designed to "cure" me of sleeping on my tummy. I am an unrepentant tummy sleeper.
Some doctors will tell you it's bad for babies, as many of the babies who suffered SIDS slept on their bellies.
Someone who suffers sleep apnea also might get problems when they do. As the lung musculature has to push more weight upwards in order to fill your lungs with air when you lie on your belly.
For everyone else, it may be uncomfortable, especially if your pillow is thick. You might get a stiff neck.
i think it's not possible to sleep in ur belly or in one single position all night thats abt 7-8 hrs avg. But in case u do sleep on ur belly all night like a statue and not move all night then it might be bad i guess.
It is bad for your back and spine. It adds pressure to your nerves and joints along the spinal cord and can develop to health problems.
ya it could be if you do it all the time
