Cushions are long, thin, and thick.
In order to prevent low back pain, a large number of sedentary people often put a cushion on the car chair, sofa and stool. Because with the popularity of office computers, people who work in a sitting position are becoming more and more popular. It is inevitable that sitting often will cause the body to feel particularly tired at the waist. But can you avoid this problem with a cushion? In fact, the answer is no, because you should use the cushion to prevent low back pain and pay attention to the method.
First of all, the cushion must be placed at the waist and it is not correct to put it on the back. This is because the normal human body has a total of 5 lumbar vertebrae. Due to physiological requirements, they do not grow in a straight line, but a convex shape that protrudes forward from the center. From the side, the lumbar vertebrae is like a gently sloping packet. Due to this physiological feature, the waist and back cannot be placed on the same plane. Therefore, the correct sitting posture should be, chest up, when the chair is needed, the waist is straight, leaving the back of the chair, sitting on the sofa as much as possible. Let the hips sit on the bottom of the sofa and the back against the back of the sofa. If you put a cushion on the waist, you can effectively support the waist, maintain the flexion of the lumbar spine, balance the pressure on the lumbar spine and lumbar muscles, reduce strain, increase the comfort of the body, prevent and improve lumbar discomfort, and stabilize the spine. benefit. Secondly, the cushions should not be too thick. It is better to use a cushion of 10 cm height. In this way, the human body is pressed backwards, just compressing 5-8 cm, which is most suitable for the physiological lordosis of the lumbar spine. Too thick will cause excessive flexion of the lumbar spine. Therefore, be careful when choosing a cushion to relieve fatigue.
For those who work in the office often, cushions are not essential, and choosing the right one is the key.
