Back Pain from Sitting in Office Chair
Back pain from sitting in an office chair can be caused by prolonged sitting, incorrect sitting posture, lack of exercise, improper selection or use of office chairs, and can be alleviated by improving habits, adjusting the environment, and engaging in appropriate exercise.

Prolonged sitting is a common cause of back pain. Maintaining a fixed sitting posture for an extended period keeps the lumbar muscles constantly tense, disrupts blood circulation, and leads to the accumulation of metabolic waste, triggering aseptic inflammation and pain. This manifests as lumbar soreness and stiffness, with slight improvement after activity. Additionally, prolonged sitting increases pressure on the lumbar intervertebral discs, potentially causing the annulus fibrosus to rupture and the nucleus pulposus to protrude outward, compressing nerve roots. In such cases, patients may experience not only back pain but also radiating pain or numbness in the lower limbs.
Incorrect sitting posture should not be overlooked. For example, an improperly adjusted chair height can cause the shoulders to hunch, the back to be unsupported, and the lumbar region to lack support, all of which can contribute to back pain. Leaning forward while working also deprives the lumbar region of effective support, keeping the lumbar muscles in a tense state for an extended period and leading to soreness.
Lack of exercise can weaken the lumbar muscles, reducing their ability to effectively support the body and increasing the burden on the lumbar region, resulting in back pain. Lumbar myofascitis can also cause widespread lumbar soreness, often triggered by cold and damp environments or long-term chronic strain.
To alleviate back pain, the following measures can be taken. Improve the work environment: Choose a chair with good support, ensuring that the elbows are at a 90-degree angle and level with the desktop, and that the lumbar support on the backrest firmly supports the lower back. Take regular breaks: Get up and move around, stretch the body, and perform lumbar stretching exercises at regular intervals, such as standing with hands raised straight above the head and bending the body to one side to feel the lumbar stretch, holding each position for 15-30 seconds and repeating 2-3 times. Apply local heat therapy daily: This promotes blood circulation and relieves muscle tension. If the pain is severe, medication for anti-inflammatory and analgesic purposes can be used under the guidance of a doctor.
