A Tip from Susan Regarding Sleeping on Your Stomach:
If you or someone you know sleeps on their stomach I encourage you to switch to back or side sleeping. In order to breathe when stomach sleeping it is necessary to turn one?€™s head. The mattress or pillow pressure with the neck in this twisted position creates a lot of spinal stress in the neck and low back especially. It can also contribute to the need for regular adjustments as well as unnecessary pain, stiffness, and decreased body function.
