Recently, there is a news on the Internet, after the investigation: often hunching, low head to play the phone easily cause the crest of the spine injury. Studies have found that because of the earth’s gravity, when the neck is bent 60 degrees, the pressure on the cervical spine will be 45 pounds. Low head on the neck caused by the impact is indeed great. Neck muscles are mainly concentrated in the back, if the head is tilted forward, the back of the neck muscles are subjected to increased tension, so keep a period of time, the back of the neck muscles are prone to strain, inflammation, pain. In the long run, it will also affect the growth of bones, leading to cervical spine curvature, which is irreversible at this time. Cervical spondylosis originally appeared in the middle-aged and elderly people, but in recent years, young people in their twenties and thirties suffering from cervical spondylosis is also more and more. Most of the patients nowadays have a common feature: cell phone dependence. On average, for every 10 young people who come to see the cervical spine, there are five or six who often play with their cell phones with their heads down. This situation can be vividly described as “cell phone neck”. In the face of “cell phone neck”, how to treat and relieve it? Many people choose cervical traction devices and other external devices. If you put it on when you are working, not only the pain of cervical spine will be reduced, but also the psychological comfort will be great. However, some patients say that after spending hundreds of dollars and using it for two to three months, there is no sign of improvement at all. Improvement of the cervical spine through traction devices will not completely cure cervical spondylosis, and is not applicable to everyone. It is understood that the traction device, ointment and other external items, the role of blood circulation, improve, relieve local muscle tension, but the root of cervical spondylosis does not help. If you do not reach the degree of cervical spondylosis, just general muscle strain, without the advice of a doctor to blindly use therapeutic equipment, once the operation is not appropriate, it is likely to aggravate the injury. To prevent cervical spondylosis, you should change your bad living habits and sitting posture, avoid long-term work and staring at cell phones and computer screens, and get up and move around for 3 minutes to 5 minutes every 45 minutes to an hour. Swimming, running, playing badminton and other sports can also relieve joint wear and tear and muscle fatigue. We would like to remind young people, especially teenagers, that if they begin to experience neck pain that lasts more than two weeks and is not relieved, they should go to the hospital in a timely manner. If you wait until it affects the growth of bones before seeking medical treatment, it will be difficult to undo.
