Shoulder pain during sleep is often caused by excessive pressure on the joint or improper neck alignment that strains the surrounding muscles. Selecting a pillow with the correct loft is vital for side sleepers to ensure the body\'s weight is distributed away from the shoulder socket, keeping the spine neutral. Memory foam and contoured designs are particularly effective at cushioning the area and preventing the collapse of the shoulder during the night. By providing consistent support and reducing toss-and-turn movements, the right pillow helps decrease inflammation and promotes better recovery for persistent shoulder discomfort.
