Impact of Low Office Chairs on the Neck

Low office chairs may have adverse effects on the neck, requiring assessment and appropriate measures based on specific circumstances.

I. Mechanism of Impact of Low Chairs on the Neck
When an office chair is too low, the human body naturally flexes or twists the neck to maintain horizontal eye level and body balance. This abnormal posture significantly increases the physiological load on the neck, causing the surrounding soft tissues, such as muscles and ligaments, to remain tense for extended periods. Without proper lumbar support, the spine tends to curve as a whole, further increasing pressure on the neck. This sustained pressure may induce or exacerbate symptoms such as neck pain and stiffness, particularly affecting patients with straightened cervical lordosis or herniated discs more significantly.

II. Specific Impact on Patients with Cervical Spondylosis
For patients already diagnosed with cervical spondylosis, sitting in a low chair is not an absolute contraindication, but risks should be carefully evaluated. If the chair is too low or the sitting posture is improper (e.g., head tilted forward, continuous contraction of shoulder and neck muscles), it may directly worsen neck symptoms. For example, patients with straightened cervical lordosis may experience greater forward head extension when sitting in a low chair, increasing disc pressure and potentially causing nerve root compression or vertebral artery insufficiency; patients with herniated discs may experience further disc protrusion due to abnormal posture, exacerbating pain or numbness.

III. Recommendations for Using Low Chairs

1. Adjust Sitting Posture and Support: Place a cushion at the waist to maintain an upright back and natural spinal curve; adjust the screen height to eye level to avoid looking down or up.
2. Regular Movement: Get up every 30-40 minutes to move the neck gently, performing side-to-side rotations and forward-backward flexions for 5-10 seconds each, repeating 3-5 times to relax muscles.
3. Seek Medical Attention Promptly: If persistent neck pain, radiating upper limb pain, dizziness, or blurred vision occur, stop using the low chair immediately and seek medical attention. Use imaging tests (e.g., X-rays, MRI) to clarify the condition and follow medical advice for traction, physiotherapy, or medication.

IV. Long-Term Preventive Measures
It is recommended to prioritize adjustable-height office chairs, ensuring that when seated, both feet are flat on the ground, thighs are parallel to the ground, and elbows are bent at 90 degrees. Additionally, strengthen neck muscle exercises (e.g., "rice-writing" exercises) and avoid prolonged低头 use of mobile phones or computers to reduce the risk of neck injury from the root.
