When the neck is bent at 60 degrees, the pressure on the cervical spine will weigh 45-50 pounds. When you maintain this position for a long time, you will experience neck discomfort, pain, stiffness, and headaches. Over time there will be distant damage to the cervical spine, even leading to impaired sensory movement of both upper limbs. So play hand games on average a few hours a day about the game time on the cervical spine damage can be imagined! Three movements to untie the cervical spine 1, chest expansion can help stretch the muscles around the thorax to restore the coordination of the thoracic bone joints; 2, shrugging helps shoulder and neck muscles to restore elasticity to ensure coordinated movement of the cervical joints; 3, neck movement and “low head” such as the opposite of the posture of chronic injury, can relax the rear cervical muscle group, stretch the front cervical muscle group and restore its elasticity.
