1, do not smoke, smoking is not good for spinal health Smoking not only hurts the lungs, but also causes irreversible effects on the spine. Cigarettes have many harmful substances, especially nicotine, if absorbed into the blood, will cause small blood vessels to contract and spasm, the caliber becomes thin, reducing the blood supply, affecting the metabolism of the intervertebral disc. Xuanwu Hospital of the Capital Medical University, Dr. Wu Hao, deputy chief physician of neurosurgery, said: smokers are prone to chronic cough, which is a trigger for disc herniation and lumbar pain. Frequent coughing and increased pressure on the lumbar intervertebral discs can lead to degeneration of the intervertebral discs. On this basis, herniated discs can cause back and leg pain with numbness and limping, which is commonly known as sciatica. 2, watching TV, sitting upright Dr. Wu Hao pointed out: people spend a lot of time watching TV in their daily lives, especially the elderly who are at home for a long time. Many people like to use the hand to support the head lying on the sofa to see, leaning against the sofa to see, or half up half lying in bed to see, these positions look very comfortable, but in fact is a very bad habit. Bad posture for too long, less activity, not timely adjustment of sitting, will increase the burden on the waist and neck, resulting in back pain and neck pain. In addition, the spine of the elderly has varying degrees of degenerative changes, such a posture is likely to cause serious spinal disorders. 3, about wearing habits (1) women wear high heels less wear high heels, the pelvis of the anterior tilt enhanced, the gravity line through the back of the pelvis, so that the waist to support the weight and increased burden, followed by posterior extension enhanced. This excessive lumbar posterior extension can lead to shoulder and back pain, chest tightness, dizziness, nausea, numbness in the upper limbs, and a pins and needles sensation when the head and neck rotate in women. (2) Men should pay attention to tie Dr. Wu Hao proposes: when tying a tie, the collar of the clothes should be loose and the tie should not be tied too tightly. Tie too tight will compress the carotid sinus, carotid artery pressure, the heart’s output blood will be reduced, thus affecting the blood supply to the brain and head and facial organs, causing vision loss, dizziness, panic, etc. 4, do not drink alcohol moderate drinking can activate blood circulation, dredge tendons and drive cold, some can also improve sleep; but excessive drinking in addition to damage the function of the liver, but also affect the activation of vitamin D, resulting in low levels of active vitamin D in the blood, reducing the metabolic function of calcium and phosphorus in the blood, resulting in osteoporosis, causing or aggravating the pain in the neck and waist.
