Common causes of shoulder pain from sleeping

The way you sleep can have a huge impact on whether you get a shoulder pain or not. Some sleeping positions are not the best when it comes to shoulder’s health; Especially with those with pre-existing joint issues.

Sleeping on your back with hands above head, or with one hand on the forehead can be bad position for your shoulders over time. While it might feel comfortable at first, this position can put strain on the shoulder muscles and joints, leading to stiffness or pain upon waking.

Also, if you have had any recent injuries regarding your shoulders, don’t sleeping on the same side as your injured shoulder. Let the area heal completely before you put any pressure on it, to avoid any chronic pain later on.
