The former Ge You Lai was called by Beijing netizens as Beijing 瘫. This posture seems to be very comfortable, but in fact it hurts the waist and easily hurts the waist. There are some movements in life that are very comfortable when they are done, but they are actually hurting the waist.
Recently, the photos of Ge You lying on the sofa burst into red on the Internet, and even netizens who opened their brains compared the "Ge You Li" with the famous paintings. Botticelli's "Venus and God of War" was also dug up. .
Analysis of the mechanism of "Ge You Li" hurting the waist
When Ge You is lying, the body and the sofa form a right-angled triangle. The lumbar spine of the person is suspended, and the shoulders and waist are the points of force. At this time, the muscles and ligaments are relaxed, the muscles of the waist are not used, and the neck can also lean against the sofa. The muscles on the neck are also in a "fake" state, and when people do not use muscles, they will feel relaxed.
However, this kind of relaxation is just an illusion! The weight of a person will not disappear for no reason. Where does this part of the weight bearing go? Originally, this part of the weight should be borne by the muscles and ligaments behind our neck, but "Geyou lay" After that, the weight is transferred to the cervical vertebra, and the spine is in an abnormally curved "twist" state, which causes tremendous pressure on the spine, especially the cervical and thoracic vertebrae, which bears the weight of the body.
Common injuries in life
1. Erlang legs
Dangerous reasons: The legs of the Erlang can cause the pelvis to tilt, the lumbar vertebrae suffer from uneven pressure, causing lumbar muscle strain, which also causes uneven force on the lumbar intervertebral disc. This position is a risk factor for lumbar disc herniation for a long time. Especially in the period of growth and development of adolescents, Changji Erlang's legs are prone to hunchback and spine curvature.
Tips: Usually try not to rub the legs of the Erlang, keep the pelvis straight when sitting down, so that the lumbar vertebrae are evenly stressed.
2. Long-term upright work
Dangerous causes: Long-term upright work can lead to tension in the lumbar muscles, increased long-term stress on the lumbar spine, and increased risk of lumbar disc herniation. For example, the salesperson is because of long-term standing work, the back and back muscles are tense, which induces lumbar disc herniation.
Tips: When you work, you can step on your feet and use your feet to increase the lumbar lordosis and relieve the tension in your lower back muscles. If you stand for a long time, you can do some stretching exercises.
3. "Old woman" sitting posture
Dangerous reason: The "old woman" sitting position means lying on a sofa or stool. This can lead to a decrease in lumbar lordosis and an increase in intervertebral disc pressure. Maintaining this position for a long time can lead to aggravation of lumbar disc degeneration.
Tips: Keep your upper body straight, abdomen, and close your legs when you are sitting. If you are sitting on a chair with a backrest, you should put your back on the back of the chair as much as possible on the basis of the above posture, so that the muscles of the lumbosacral region are not too tired.
4. Poor sleeping position
Dangerous reasons: If you don't have support at the neck and waist when you are lying down, it will cause tension in the back and back muscles. This is why many people feel that the waist is very uncomfortable after sleeping on a sofa or a soft bed.
Tips: Try to choose a slightly stiffer mattress when you sleep, and put a soft pillow under your knee when you are lying down. This can make the hip and knee joints slightly flexed, the back and back muscles relax, the intervertebral disc pressure is reduced, and the disc herniation is reduced. risks of.
5. Poor running posture
Dangerous reasons: Running is a sport that many people like, but abnormal running postures, especially when the bow is tilted forward, can cause a significant increase in the force of the disc. Together with the pulsed pressure of running bumps, it will affect the disc. The risk is greater.
Tips: Patients with lumbar disc herniation are not recommended for strenuous exercise, such as climbing, running, cycling, etc. If you are jogging, try to keep your upper body straight and run slowly. Wear air-cushioned shoes to reduce the pulse pressure on the intervertebral disc.
6. The need to twist the movement
Dangerous reasons: Some movements that need to be twisted, such as golf swings, ping-pong arcs, or twisting exercises during exercise, require the waist to force the arm, so that the normal twisting motion causes long-term twisting of the intervertebral disc. And squeezing is a high-risk action of disc herniation.
Tips: Patients with lumbar disc herniation should try to avoid doing some exercise that requires twisting. Normal people should also do waist protection and prevention during exercise.
7. Wear high heels
Dangerous reason: the sole has a foundation function, which directly affects the weight of the person. Wearing high heels will cause the body's center of gravity to move forward too much, which will inevitably cause the pelvis to lean forward, the curvature of the spine will increase, and the lumbar vertebrae will become concentrated. It is easy to cause disc damage in the long run.
Tips: Usually wear flat shoes as much as possible, office workers can prepare double flat shoes in the office. If you have to wear high heels for special occasions, try to focus on the heel instead of the forefoot while walking.
8. Chronic cough, constipation
Dangerous causes: Long-term chronic cough and constipation can lead to increased abdominal pressure, which can also increase the force on the intervertebral disc, which is also a clear risk factor for lumbar disc herniation. The waist will also exert force when coughing. For patients with lumbar disc herniation, severe cough will involve waist pain.
Tips: If you have symptoms of chronic cough and constipation, be sure to treat the cause in time. If dragged, not only may the condition be aggravated, but it may also cause or aggravate symptoms such as lumbar disc herniation.
