Cushion use matters

With the popularization of mechanization and office computers, people who work in a sitting position are becoming more and more common. Some sedentary people in order to prevent low back pain, often in the car chair, sofa, stool put a cushion. The doctor warned that using cushions to prevent low back pain should also pay attention to methods.

The doctor pointed out that the cushion should be placed on the waist, and it is not correct to put it on the back. This is because there are 5 lumbar vertebrae in normal human body. Due to physiological needs, they do not grow in a straight line, but are convex in front of the middle part. Seen from the side, the lumbar vertebrae are like a small bag with gentle slope. Because of this physiological characteristic, the waist and back cannot be placed in the same plane. Therefore, the correct sitting posture should be to raise your head with your chest raised. When you need a chair, your waist should be straight, leave the back of the chair, and sit back as much as possible when sitting on the sofa. Let your hips sit at the bottom of the sofa with your back close to the back of the sofa. If a cushion is placed on the waist, it can effectively support the waist, maintain the flexion physiology of the lumbar spine, balance the pressure of the lumbar spine and lumbar muscles, reduce strain, increase somatosensory comfort, prevent and improve lumbar discomfort, and stabilize the spine. Good. Secondly, the cushion should not be too thick, and the cushion with a height of 10cm is better. In this way, the human body presses backward, just compressing 5-8cm, which is in line with the physiological lordosis of lumbar vertebrae. Too thick will cause excessive lumbar flexion.
