From the side, the human spine is like two S-shaped, the thoracic vertebrae are convex, the cervical vertebrae and the lumbar vertebrae are convex forward. Due to this physiological feature, the waist and the back are not in a straight line, so we have a cushion for a long time. Relieving the pressure on the waist, the support of the cushion maintains the physiological characteristics of the flexion of the lumbar spine, balances the pressure of the lumbar and lumbar muscles, relieves fatigue, and can prevent and improve the discomfort of the lumbar spine, which is beneficial to stabilize the spine. Therefore, the cushion should be placed at the waist to play a real role. Ju Menglai Aijia consultant introduces the functional characteristics of the cushion and the related knowledge points that should be paid attention to when using it.
The thickness of the cushion should be moderate, based on comfort, not too thick or too thin, not too soft or too hard. Too thick may cause excessive flexion of the lumbar spine, and too hard will make people 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. No matter what job you do, as long as you have been sitting for 45 minutes, you should get up and do stretching exercises. This is good for your eyes, wrists, cervical vertebrae, and lumbar spine. Don't always have a posture during work. You should change your posture after a while. 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. When sitting on the sofa, try to sit back and let the hips sit on the sofa. At the bottom, the back is close to the back of the sofa. Yu Menglai Home Textiles Consultant reminds that when you feel that your back is overwhelmed, you must not stick to work, but rest immediately. A moment of rest can also effectively reduce the strain on the psoas. (Gu Menglai Home Textiles)
