Prolonged sitting is one of the primary causes of lumbar disc herniation (commonly known as a slip disc). When you sit, the load on your lower spinal discs is up to 3 times greater than when you stand. Over time, this pressure causes the outer fibers of the disc to tear, leading to bulging and nerve compression.

Rule 1: Maintain the 90-90-90 Seated Position

Keep your knees at a 90-degree angle, hips at 90 degrees, and elbows rested at 90 degrees. Your feet must rest flat on the floor or a footrest.

Rule 2: Support Your Lumbar Curve

Use a chair with built-in lumbar support or place a small rolled towel behind the natural curve of your lower back. This maintains the lordotic curve, preventing disc compression.

Rule 3: Set Your Monitor at Eye Level

The top third of your computer screen should be at eye level. This prevents forward head posture, which strains the cervical spine and shoulders.

Rule 4: Follow the 30-Minute Movement Rule

Set a timer to stand up, stretch, or walk for 2 minutes every 30 minutes. This offloads static spinal pressure and restores circulation to the discs.

Rule 5: Keep Keyboard and Mouse Close

Avoid reaching forward for your keyboard or mouse. Keep them close enough so your upper arms hang relaxed by your side, reducing upper back tension.
