During our sleep, we remain stationary for hours. This obviously creates stress for back muscles and ligaments. Besides, during a sound slumber, the muscles get relaxed and the healing speeds up. Hence, it is important to align the spine correctly during sleep. The American Chiropractic Association approved and recommended two methods of sleeping. Sleeping on the back is desirable and sleeping on sides is acceptable but sleeping on the stomach is not the ideal position.
For individuals who are wheelchair users, sleep is the only time to relax the back muscles. Hence, they must be positioned correctly to prevent any further stress. Let me assure you, the choice of mattress has a role in this.
