The cushion is too thick and easy to "fold the waist".
From the time I walked into the office, I sat in front of the computer and worked until I got off work. Now, such office workers abound. In the clinic of the Chief Physician of the Department of Orthopaedics, Beijing Hospital of the Ministry of Health, the patient is often referred to a patient who suffers from low back pain due to sedentary. To this end, the road director suggested that in order to prevent low back pain, you may wish to put a cushion on the computer chair. Cushions can indeed relieve the muscles of the lumbar muscles, but there are also a lot of stress when using the cushions.
First of all, the cushion must be placed at the waist, and it is not effective to put it on the back. This is because the normal human body has three physiological curvatures. Because of physiological requirements, they do not grow in a straight line. The thoracic vertebrae are convex, and the cervical and lumbar vertebrae are convex forward. From the side, the spine is like the connection of two S. Due to this physiological feature, the waist and back cannot be placed on the same plane. Therefore, when sitting in a computer chair, if you put a cushion on the waist, you can effectively support the waist, maintain the flexion of the lumbar spine, balance the pressure of the lumbar spine and lumbar muscles, reduce strain, increase comfort, prevent and improve the lumbar spine. Discomfort is good for stabilizing the spine.
Secondly, the thickness of the cushion should be appropriate. Can not be too thin and too soft, so that it can not lift the waist, not too thick and too hard, too thick may cause excessive flexion of the lumbar spine, and too hard will be uncomfortable. The cushion can be placed behind the waist during the selection. If the cushion still feels comfortable after ten minutes, the thickness is suitable. If the back is tired or even painful, the cushion is unqualified. Furthermore, people who already have lumbar disc herniation and lumbar spinal stenosis should pay more attention to the comfort of the cushion.
In addition to the use of cushions to relieve low back pain, there are some details for the office family should also pay attention to. The director of the road said that no matter what job you are doing, as long as you have been sitting for 45 minutes, you should get up and do stretching exercises, which will benefit your eyes, wrists, cervical vertebrae and lumbar vertebrae. During work, don't always have a posture, it should be separated after a while. Changing a posture and constantly adjusting the posture can also relieve the tiredness of the waist. The correct and proper sitting posture should relax the body; when it is necessary to rely on the back of the chair, the waist should be straight, and when sitting on the sofa, try to sit back and let the hips sit. At the bottom end of the sofa, the back is close to the back of the sofa. In addition, when you feel that your back is overwhelmed, don't stick to work, but rest immediately. A moment of rest can also effectively reduce the strain on the psoas.
