There are many people suffering from “lazy cancer” in daily life. In line with the principle of “can sit and never stand, can stand and never lie down”, go out to find every opportunity to sit , to find every opportunity to lie down at home. Lying down to sleep and playing with mobile phones is comfortable, but is it the most labor-saving and the least damage to the lumbar spine? Does standing definitely cause the most damage to the lumbar spine? Let’s take a look today.
Which position, sitting, standing or lying down, puts the most pressure on the lumbar spine? The answer may not be what you think.
In most people’s opinion, standing posture is the most tiring, and the lumbar spine will bear the greatest pressure and cause the greatest damage to the lumbar spine, but this is not the case. According to research, if we set the pressure on the lumbar column in the standing position as 100%; then the pressure on the lumbar column in the lying position is only 25% of that in the standing posture; compared with the standing posture, the sitting posture gives the waist The pressure brought about is greater, reaching 140%, and the damage to the lumbar column is the largest. It can be seen that compared with the three postures, the sitting posture brings the greatest damage to the waist. When we are in a sitting position, our lower limbs have almost no force, and we mainly rely on the support of the spine. At this time, the pressure on the spine is greater than that when standing.
Especially Poor sitting postures such as leaning forward, sitting cross-legged, and hanging the lower back may cause degenerative changes in the lumbar intervertebral disc, strain, loosening of the lumbar spine, pain, spasm, etc. symptom.
Nowadays, the number of people such as “workers”, “students”, “lazy people” is increasing, and sedentary behavior has become a very common phenomenon. The phenomenon has also led to more and more people with waist injuries, and the number of people suffering from lumbar spine diseases is increasing. According to the data, there are more than 200 million lumbar spine patients in my country, of which the young people aged 25-39 are the first in all age groups. The detection rate of lumbar disc herniation is as high as 13.93%, of which 60% of the patients are caused by poor sitting posture.
From this point of view, bad sitting posture has seriously affected our life, and will also bring physical pain. Therefore, in normal times, everyone should pay attention to their sitting posture, do not do some bad habits, and maintain the correct posture. When making a chair, it is best to keep your back and hips close to the chair, or to make it harder do not allow the lumbar spine to hang in the air. Usually, it is best to get up and walk every half an hour or an hour to promote blood circulation, and also to combine work and rest to avoid damage to the psoas muscle and cause lumbar spine disease. In fact, the pressure on the waist in sitting, lying, and standing postures is still defined in the case of standard movements, and how many people can really achieve standard postures?
Actually, the posture that hurts the lumbar spine the most is “paralyzed”
I think everyone likes to be paralyzed. When you come home from work, it’s like being drained of energy. Not wanting to move, he turned on his mobile phone to order takeout, and “Ge You lay down” slumped on the sofa to play with his mobile phone for an hour or two. You are comfortable, and you have thrown the “unbearable” weight on your waist. Have you considered how it feels?
See this many people Some people may have doubts, it is obviously more comfortable to be paralyzed than to sit upright, how could it still hurt the waist? This is because the muscles that mainly exert force when we are in a sitting position are the small muscles next to the lumbar spine< /strong>, and when paralyzed, the large muscle groups that consume more energy and are better at exerting force will also participate in exerting force, and it is easier to feel fatigued. Over time, muscle damage will be the first to fail, and when the lumbar spine can no longer be stabilized, it may cause lumbar spine injury, overstretching and loss of elasticity of ligaments, and lumbar disc herniation.
It can be seen that this habitual paralysis may be the cause of your frequent backache and low back pain. You must pay attention to your normal sitting posture in normal times, try your best to sit up straight, keep your back close to the chair, and keep your lumbar spine. Normal physiological curvature, thereby reducing the burden on ligaments and muscles and reducing the pressure on the waist.
