Can correct kneeling method cure the disease caused by sitting out?

Recently, the editor has been complaining about back pain, but I haven't seen her doing any physical work, or exercising every day like Rong Ge. It is basically certain that it is the so-called office occupational diseases: cervical spondylosis, lumbar muscle strain, lumbar disc herniation. These can be said to be caused by, uh... sitting. Incorrect sitting posture will definitely cause serious harm to the body, so today Rong Ge must recommend a healthy sitting posture to you.

First of all, most of the sitting posture problems are reflected in the cervical and lumbar vertebrae. When the lumbar vertebrae are slightly protruding and naturally curved, it is in line with the healthy sitting posture. On the contrary, if the lumbar vertebrae are protruding, it will cause lumbar disc herniation, waist muscle soreness, neck and back fatigue, etc. The structure of the spine is very complex, including 7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae and 4 coccyx, which are connected together by intervertebral discs and ligaments and are the main pillars of the human body.

The most natural posture for the human body is standing upright. When viewed from the side, the spine of an adult is in an S-shaped curve, which is also the healthiest shape. From an anatomical point of view, the change in the shape of the spine is the biggest difference between sitting and standing. Some scholars believe that the closer the spine is to its natural upright state in a sitting position, the healthier it is. Unfortunately, when most people sit, their pelvis tilts backward, causing the sacrum at the lower back to tilt as well, changing the spine from an S-shape to an arch shape. This puts a lot of pressure on the intervertebral discs, making them prone to damage or bending and deformation.

Is there a sitting posture that can make the spine close to the state of standing? There must be one! The most correct sitting posture is kneeling. Kneeling was called sitting upright in ancient times. Many people mistakenly believe that it was the reason for the ancients to wear it, just to cover up shame, and there is no practical benefit. In addition, kneeling for a long time will make the knees uncomfortable. Some people even think that the Japanese like to sit upright and cross their legs, so they have bow legs.

Here we have to make it clear that the correct sitting posture is to keep the heels together, the legs and knees together, and ensure that the feet and legs are placed in the same direction as the knees. In this case, the femur and tibia, that is, the thigh and calf, are in a straight line, and the ischium is vertically downward, so the pelvis is also straight, which will not have any adverse effects on the knees. Moreover, this is the ultimate flexion training movement in joint rehabilitation for people with knee injuries after surgery. As for why it is emphasized to be in a straight line, it is because it is dangerous, dangerous, dangerous! When the knees spread out, it means that the femur rotates outward, causing the pelvis to spread outward. The more it spreads outward, the more the legs spread outward, and it continues in a vicious cycle.

So as long as you have a standard posture, there are many benefits to sitting upright. Sitting upright can reduce the occurrence of hunchbacks, and people will habitually keep their upper body upright. When sitting upright, the blood circulation function of the stomach will also be enhanced. In simple terms, it helps digestion and relieves constipation. In addition, sitting upright is more beneficial to men's health and can reduce the incidence of impotence!

However, Rong Ge has to remind everyone that even if you sit upright correctly, it is easy to compress the metatarsal bones, which is the front half of the sole of the foot, and may cause stress fractures. If you have injured your knees and ankles, please do not force yourself. If you can't sit upright, it means that there must be something wrong with your hips, knees, and ankles. While sitting upright, you should practice exercises to improve the problems. You didn't expect that sitting upright is actually a technical job. Remember to proceed step by step and do it according to your ability.

As for the origin of sitting upright, there are many hypotheses, the most reliable of which should be the "semi-underground theory": people in the Shang and Zhou dynasties lived in semi-underground buildings. In order to prevent moisture and keep warm, they would spread thick cushions on the ground and sit on the ground, which was convenient and comfortable. So back to modern times, in this spring season, when we go out for an outing, we spread out a picnic mat and sit on the ground. Would you or can you choose to sit upright?
