How to use the cushion

With the popularity of mechanization and office computers, people who work in a sitting position are becoming more and more common. Some sedentary people often put a cushion on the car seat, sofa, and stool in order to prevent low back pain. The doctor reminded that it is also necessary to pay attention to the method of using cushions to prevent low back pain.

The doctor pointed out: First of all, the cushion must 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 a normal human body. Due to physiological needs, they do not grow in a straight line, but in a lordotic shape with the middle protruding forward. Viewed from the side, the lumbar vertebrae are like a small bag with a gentle slope. Due to this physiological characteristic, the waist and back cannot be placed on the same plane. Therefore, the correct sitting posture should be to keep your chest up and your head up. When you need to lean on the chair, keep your waist straight and leave the back of the chair. When sitting on the sofa, try to sit as far back as possible.
Let the buttocks sit on the bottom of the sofa surface, and the back is close to the back of the sofa. If a cushion is placed on the waist, it can effectively support the waist, maintain the forward bending physiology of the lumbar spine, balance the pressure on the lumbar spine and lumbar muscles, reduce strain, increase physical comfort, prevent and improve lumbar discomfort, and have a positive effect on stabilizing the spine. benefit. Secondly, the cushion should not be too thick, preferably a cushion with a height of 10 cm. In this way, the human body presses backwards, compressing exactly 5-8 cm, which is most in line with the physiological lordosis of the lumbar spine. Too thick will cause excessive forward flexion of the lumbar spine.
