Lower Back Pain from Sitting: Causes & Fixes

Lower back pain from sitting is a common complaint that can disrupt daily life and work. Understanding the causes and implementing simple changes can significantly reduce discomfort.

Why Sitting Causes Pain

Sitting for more than 30 minutes increases disc pressure by up to 40% compared to standing. This sustained load, combined with a flexed spine, strains the lower back muscles and ligaments.

The 30-Minute Rule

Stand up and move for at least 2 minutes every 30 minutes. This simple habit reduces disc compression and muscle fatigue, cutting pain risk by over 50% in most people.

Posture and Support

Use a chair with lumbar support that maintains the natural curve of your spine. Adjust the seat height so your hips are at 90 degrees and your feet are flat on the floor.

The most common mistake

The most common mistake is sitting for hours without a break, believing good posture alone is enough. Even perfect posture becomes harmful if held for more than 30 minutes.
