Dr. Peter Martone, owner and director of Atlantis Chiropractic Wellness Centers in Wakefield, Massachusetts, explains why you should sleep on your back, not your side.

"The curves of your spine are the shock absorbers of your spine, so they absorb stress" says Dr. Martone.

To maintain healthy curves of the spine and reduce lower back pain, Dr. Martone recommends sleeping on your back with a "pillow garage" to support your neck. He demonstrates the spine curvatures and pillow placement in this video.
