People often jokingly say: “sitting and talking is not waist pain.” Is this really the case, we have always felt that sitting down to rest, that “sitting” is a kind of rest, but for the lumbar spine is an exception. The human body normally has four physiological curvature, the formation of the inherent physiological force line and stress points. Lumbar spine due to long-term poor posture (such as sedentary, prolonged bending force, etc.), the spine stress increases, aggravating the degeneration of the intervertebral disc. Loss of water in the nucleus pulposus of the intervertebral disc, weakened elasticity, increased brittleness, easy rupture of the fibrous ring, when a certain external force (may be a car accident, trauma, may also be bending down to pick up a thing), the tearing of the fibrous ring, the protrusion of the nucleus pulposus, resulting in lumbar spondylosis. So sitting for a long time, always in a posture, will increase the damage to the lumbar spine and lumbar pain will occur. Science is developing, and our perceptions have not yet changed. Small habits that are neglected in daily life are often the big key to getting lumbar spondylosis. How to get rid of lumbar spondylosis? How to protect our lumbar spine? 1, it is recommended not to sit for a long time Sitting for a while can get up and stand. Research has proved that, lying down, the spine carries about 25% of the weight of the pressure; standing, about 100% of the weight of the pressure; sitting, about 150% of the weight; and bending about 200% of the weight of the pressure; leaning forward when sitting (such as incorrect use of the computer) about 250% of the weight of the pressure. 2, the correct sitting posture: sitting upright, chest and abdomen, forearm support, the seat is not too deep, the back close to the back of the chair, can be properly protected with a hard back cushion support. 3, appropriate functional exercise can improve local blood circulation, reduce and eliminate edema in the soft tissue around the lumbar disc, delay and prevent disc protrusion. The following lumbar health exercises: (1) lumbar stretching exercises; (2) fish leap lumbar back muscle exercise.
