How you hold your phone and use a computer can tell a lot about the liklihood of developing chronic neck tension and other symptoms that are caused by cervical spine instability. The easiest way to start reversing the effects of the facedown, forward head lifestyle is to adjust your computer screen and start holding your phone at eye level or using prism glasses to allow you to keep your head, neck, and chest in good alignment while you look down at your phone. Wish you all the best in health!
