Lower Back Pain from Sitting on an Office Chair
Lower back pain from sitting on an office chair can be alleviated by adjusting the chair, posture, taking regular breaks, applying heat therapy, strengthening the back muscles, and using medications appropriately.
Adjust the Chair: Choose a chair with a backrest and ensure it is at the right height so that your feet are flat on the ground, with your knees and hips at a 90-degree angle. The backrest should follow the natural curve of your spine, and the lumbar support should firmly press against your lower back. If you cannot achieve these three 90-degree angles, try using a footrest or adding cushions behind your back to maintain these angles as much as possible, reducing pressure on your lower back.
Adjust Your Posture: Maintain the natural curve of your lumbar spine and avoid prolonged slouching or leaning forward. Use an ergonomic lumbar support when working at a desk, and adjust your posture slightly every 30 minutes. When sitting, try to keep your buttocks pushed back and your lower back pressed against the chair back, keeping the muscles in your lower back and legs relatively relaxed and reducing continuous tension in your lower back muscles.
Take Regular Breaks: Sitting continuously for more than an hour can lead to poor blood circulation in your lower back. It is recommended to get up and move around for 3-5 minutes every hour, performing gentle stretching exercises such as waist rotations and side bends, or engaging in low-intensity activities like standing against a wall or walking to promote blood circulation in your lower back and relieve muscle fatigue.
Apply Heat Therapy: For chronic strain-related lower back pain, apply a warm towel at around 40ยฐC to your lower back for 15-20 minutes, 2-3 times a day. Heat therapy can dilate blood vessels and accelerate the removal of metabolic waste, and gentle massage can enhance its effects. For acute sprains, apply cold therapy within the first 48 hours and switch to heat therapy later. The choice of physiotherapy equipment should be guided by a doctor to avoid worsening symptoms due to improper use.
Strengthen Back Muscles: It is recommended to perform core muscle training such as the Superman, bridge, and plank exercises daily for 10-15 minutes each time. Swimming and the cat-cow pose in yoga can enhance the endurance of your back muscles and improve lumbar spine stability. Exercise gradually and avoid strenuous activities that may aggravate injuries. Patients with osteoporosis should adjust the intensity to ensure safe and effective exercise.
Use Medications: For significant pain, use nonsteroidal anti-inflammatory drugs (NSAIDs) such as diclofenac sodium sustained-release tablets or celecoxib capsules, or topical flurbiprofen gel patches as directed by a doctor. Patients with muscle spasms can take methocarbamol tablets in combination. Patients with osteoporosis should use anti-osteoporosis drugs such as alendronate sodium tablets in combination. All medications should be used after excluding contraindications to avoid adverse reactions.
