Spinal cord diseases are gradually becoming younger, with a rapidly growing trend of people under 30 years of age. Often hunchback, head down and play with the phone easily cause spinal injury. Because of gravity, when the head is bent 45 degrees, the pressure on the cervical spine can be up to 45 pounds! LBS is pounds, 1 LBS = 0.4536 KG When the body is upright, the weight borne by the cervical spine is the weight of the head, but when the head is tilted, the force on the cervical spine will also change. Since the weight of the head is constant, then the additional weight on the cervical spine comes entirely from the tension generated by the muscles. The lower the head cervical disc pressure will be greater, cervical spine each segment inside a disc, the longer the head down, the greater the angle, the greater the force on the intervertebral disc and cervical vertebrae will be.
