There are many people who feel so comfortable sitting in life, so there are various sitting postures. We are going to say today, it is related to the sitting posture. 30-year-old Ms. Wang suffered a big loss because of her poor sitting posture. Just in time for the holidays, they are too lazy to go out to exercise at home, sitting on the sofa or bed, playing cell phones and iPads, lying in the same position and just said the Beijing palsy. I think we have all had this experience of sitting down, nestled in bed or on the sofa, a paralyzed for several hours. If you fall asleep on the couch after work, accidentally, a paralysis is a night. This patient stayed at home for more than a week and suddenly found that his hands were numb and weak, his legs were wobbly and the soles of his feet were soft like stepping on cotton, and it gradually worsened, and he felt that his whole body was not working. He came to the hospital for a checkup, and when he had an MRI, the whole spinal cord was almost crushed. The above picture is the legendary MRI of the cervical spine, marked with a number of bones, between the bones there is a soft intervertebral disc cushion. If a person sits for a long time, the neck nestled in the sofa or bed, the force on the cervical spine will be uneven, which will lead to the rear ligament tear, all the discs inside protrude backward, compressing the spinal cord, light hand numbness discomfort, heavy limb paralysis. If the cervical spondylosis to such a serious degree, do not hard, should be as soon as possible to the hospital, so as not to delay the best time for treatment. The correct posture of office workers due to long-term head down at work, so that the muscles of the neck in a long-term non-coordinated stress state, the ligaments and muscles of the back of the neck is easy to be strained, strain, while the front edge of the vertebral body due to mutual wear and tear and hyperplasia, cervical disc aging, and chronic strain, resulting in cervical spondylosis.

Correct sleeping posture Speaking of sleeping posture, sleeping on a hard bed is a good choice, because it can support the body more in place. Try to use the supine style rather than side lying, to ensure that the spine gets the complete support of the bed board, and the shoulders will also become straight. The choice of pillow also needs more attention, flat pillows are more suitable for supine, while fat pillows are suitable for side lying. Prone, half prone, half supine or upper and lower body twist and sleep, are bad sleeping posture, should be corrected in a timely manner.
