Why do people have more and more neck and back pain nowadays? This is because people’s daily work and life, “sitting” time is increasing. Today, people spend 90% of their day sitting in a chair, except for sleeping. In addition, there is a lot of work and leisure, sports are also done with the head down and bent, or repeatedly low and repeatedly bent in. Can this also cause neck and back pain? Let’s review the evolution of human beings! Humans evolved from reptilian vertebrates in ancient times. After an evolutionary process of about half a million long years, humans stood up. Slowly, in order to adapt to daily work and life, these forelimbs gradually evolved into the present-day hands. However, the human spine still retains the form and structure of a reptilian vertebrate. Doctors often say “physiological curvature” (cervical vertebrae, lumbar vertebrae bent backward, arching forward; thoracic vertebrae bent forward, arching backward), is the long-term crawling posture, the body by the gravitational force of the earth’s core and the formation. Today, technological progress and the continuous development of social civilization, most of the work of human society is done sitting and head down, bending over to do. This posture, people’s neck and lumbar spine are bent forward, backward arch, is the exact opposite direction of the physiological bending posture. For example, facing the computer work white-collar workers, electronics and garment factory workers, teachers and students in schools, bent over workers on construction sites, etc., involving all walks of life; even, some people who have nothing to do in parental time watching TV, playing mahjong; in the long run to work and live in a posture that violates the physiological characteristics. In this way, the posterior side of the anatomical structures of the neck and lumbar long-term undergo excessive pulling force stimulation, resulting in strain, hypertrophy, hyperplasia; intervertebral disc and its nucleus pulposus backward extrusion, backward movement, protrusion compression of blood vessels, nerves, causing headache, dizziness, shoulder and back pain, upper/lower limb numbness and weakness, sciatica, etc., a series of symptoms. The causes of neck and lumbar pain are understood, and its prevention is easy to grasp. As the old saying goes: sit like a bell, stand like a pine. Since the majority of our daily work and life is sitting, to avoid the occurrence of neck and lumbar pain, we must “sit like a bell”, the key to sitting is to straighten the waist forward. Every 1 – 2 hours, get up and move around for more than 10 minutes and do radio gymnastics. It’s too easy, isn’t it? You have to do to keep your waist straight for a long time, sitting straight is not simple. Don’t rush! International authorities have proven that as long as you can persist and pay attention to correct your sitting posture, you will be able to develop correct sitting habits after three months. Habit becomes nature! At this point, the demons of neck and back pain will be far away from you! In addition, avoid bending forward and repeatedly bending forward for a long period of time as much as possible; when it is unavoidable, stand up after work and bend your neck and waist backward repeatedly. Habit becomes nature! Then, the demons of neck and back pain will be far away from you! Neck and lumbar pain is mostly a problem with the mechanics of the spine, so injections and medication only treat the symptoms but not the root cause. If you have recurrent neck and lumbar pain, you should see a doctor as soon as possible and use the correct treatment of medical physics and biomechanics. Timely correction of mechanical problems, release the abnormal mechanical stimulation of the spine and surrounding soft tissues, to avoid long-term stimulation and produce osteophytes, herniated discs, ligament and muscle strain, spinal deformities and other conditions.
