Best sleeping position for best support: Most people have one favorable position for sleep. According to research, about 65% of people prefer side sleeping, 30% sleeping on the back, and 5% prefer sleeping on the stomach. Sleeping on the back will provide the best support for your spine, first the body weight is spread evenly over a larger surface, secondly spinal curvatures are mostly keep in their neutral position. For side sleeping, neck should stay in a horizontal position with proper pillow support. The improper sleeping position is on the stomach, this will increase the spinal curvatures causing pressure to the spinal joints and tension to the soft tissues. In addition, sleeping on the stomach will put weight-bearing pressure on the rib cages and pressure to the diaphragm and lungs affecting the breathing. Further more, the neck needs to be turned and twisted, increase the chance of spinal misaligments and soft tissue injury.
