An estimated 80 percent of adults will experience back pain at some time in their lives. For some, the back pain may be caused or exacerbated by the way they sleep. The best sleep positions will keep your spine in a neutral position or match the natural contour of the spine. The best sleep position to keep your spine neutral is on your back. When you sleep on your back, place a pillow under your knees and a little roll underneath the small of your neck. The pillows will help you maintain the natural curves of the spine.
