This can place strain on the neck.
It may also increase pressure on the lower back if the body is not properly supported.
For these reasons, stomach sleeping is generally not considered the best position for maintaining comfortable spinal alignment.
If you naturally sleep on your stomach and have no discomfort, you may still be able to make the position more comfortable by using an appropriately supportive mattress and a relatively thin pillow.
4. The Best Position for Back Pain
People with back pain may benefit from sleeping in a position that keeps the spine in a comfortable and relatively neutral alignment.
For some people, sleeping on the back with a pillow underneath the knees can help.
For others, sleeping on the side with a pillow between the knees may feel better.
There is no universal rule.
The most important factor is whether the position reduces discomfort and allows you to sleep comfortably.
If back pain is severe, persistent, or associated with weakness, numbness, or other concerning symptoms, medical evaluation may be necessary.
5. The Best Position for Acid Reflux
Sleeping position can affect symptoms of acid reflux.
For some people, lying on the left side may reduce nighttime reflux compared with lying on the right side or back.
