Back Pain from Sitting in an Office Chair
Back pain from sitting in an office chair is mainly related to inappropriate chair height, lack of lumbar support, prolonged sitting, incorrect sitting posture, and lack of exercise. It can be alleviated by adjusting the chair, improving sitting posture, controlling sitting time, and strengthening exercise.
1. Adjust Chair Height and Lumbar Support
Inappropriate chair height can lead to uneven force distribution across the body, increasing the burden on the lower back. The correct adjustment method is to sit with the elbows naturally bent at a 90-degree angle and level with the desktop. At this time, the thighs should be parallel to the ground, and the feet should be flat on the ground or on a footrest. If the chair is too high, the legs will be suspended, forcing the lower back to lean forward; if it is too low, bending over will be required, both of which will increase the pressure on the lumbar spine.
Insufficient lumbar support is another common cause. Choose an office chair with an adjustable lumbar support to ensure that the lumbar support can press against the lower back (the position of the 3rd to 5th lumbar vertebrae) to form natural physiological curvature support. If the chair has no lumbar support, a cushion or a rolled-up towel can be placed behind the lower back to fill the gap between the lumbar spine and the chair back and reduce muscle fatigue.
2. Correct Incorrect Sitting Posture
Incorrect sitting posture can directly lead to abnormal force on the lower back. The correct sitting posture should be: keep the back straight, relax the shoulders, and look straight ahead at the computer screen (the center of the screen should be at the same height as the eyes), avoiding rounded shoulders or excessive forward leaning. If you need to work at a desk, you can raise the monitor or use a stand to keep your line of sight perpendicular to the screen and reduce the่ฟๅธฆ impact of neck extension on the lumbar spine.
3. Control Sitting Time
Prolonged sitting can keep the lower back muscles continuously tense, reduce blood circulation, and accelerate lumbar spine degeneration. It is recommended to get up and move for 3-5 minutes every 30-45 minutes of sitting and perform simple lower back stretching exercises, such as standing with hands on hips and slowly rotating the lower back to the left and right, or leaning back as far as possible and holding for 5 seconds, repeating 3 times. In addition, avoid maintaining the same posture for a long time and alternate between sitting and standing while working (such as using a sit-stand desk).
4. Strengthen Lower Back Exercises
Lack of exercise can lead to weakened lower back muscles, which cannot effectively support the spine. Daily core muscle group training can be carried out, such as plank exercises and the "Superman" exercise (lifting the head and legs while lying prone) to strengthen the lower back muscles. Swimming (especially breaststroke) is also an excellent exercise for protecting the lumbar spine. The buoyancy of water can reduce the pressure on the lumbar spine while exercising the coordination of the whole body muscles.
