Waking up with a stiff neck from sleeping can be surprisingly painful. You might not even be able to turn your head without it hurting. While it may not affect you after a few hours, a stiff neck can bring excruciating pain first thing in the morning. It's no way to start the day.
But the good news is that solving this problem could be as simple as switching out your pillow. Awkward neck positions, muscle strain, and poor sleep posture are all causes of stiffness when sleeping. If your pillow isn't supporting your neck and head properly, it could be to blame. Even if your neck pain began from a sports injury, the wrong pillow could be contributing to and aggravating issues further.
