Danger index ★ Always cross your legs
Crossing your legs will lead to pelvic tilt, uneven stress on the lumbar spine, strain on the lumbar muscles and uneven stress on the lumbar intervertebral disc. Maintaining this posture for a long time is a risk factor for lumbar disc herniation.
Suggestion: Try not to cross your legs at ordinary times. Keep the pelvis straight when sitting down, so that the lumbar spine is evenly stressed, especially when teenagers are in the growth and development period. Don't cross your legs, otherwise it is easy to form hunchback and spinal curvature.
Danger index ★ Long-term standing work
Long-term standing work will lead to lumbar muscle tension, long-term stress on the lumbar spine and increased risk of lumbar disc herniation. Many people have tense back muscles because of standing and working for a long time, thus inducing lumbar disc herniation.
Suggestion: Spinning your feet on tiptoe at work can increase lumbar lordosis and relieve back muscle tension. If you stand for a long time, you can do some waist stretching.
Danger index ★★★★ Bad sleeping position
When lying flat, if the neck and waist are not supported, it will lead to muscle tension in the back, which is also the reason why many people feel uncomfortable at the waist after sleeping on the sofa or soft bed.
Suggestion: Try to choose a slightly harder mattress when sleeping, and put a soft pillow under your knees when lying flat, which can make your hips and knees slightly flex, relax your back muscles, reduce the pressure on the intervertebral disc and reduce the risk of disc herniation.
Risk index ★★★★★ Long-term paralysis
Long-term paralysis refers to sitting on a sofa or stool, some of which are similar to "Ge You Lie". Such sitting paralysis will lead to decreased lumbar lordosis and increased intervertebral disc pressure. Maintaining this posture for a long time will lead to aggravation of lumbar intervertebral disc degeneration, and over time, it is easy to really "paralysis".
Suggestion: when sitting, keep your upper body straight, abdomen in, and lower limbs close together. If you are sitting in a chair with a backrest, you should try to keep your back close to the back of the chair on the basis of the above posture, so that the muscles of the lumbosacral region will not be too tired.
Danger index ★★★★★★ Single person carrying heavy objects
One-handed weight will make the whole body tilt, the direction of intervertebral disc stress is uneven, and the muscle tension is different. One-handed force, uneven weight distribution, will make the two sides of the spine uneven, which will do great harm to the intervertebral disc.
Suggestion: Try to lift objects with the same weight with both hands to ensure the balance of the trunk and the uniform stress on the lumbar spine. Don't suddenly use too much force when lifting heavy objects, and don't change your posture with too much force.
