LOWER BACK PAIN FROM SITTING IS NOT JUST MUSCLE FATIGUE — IT IS MECHANICAL DISC COMPRESSION OVER TIME
Sitting for long periods — especially with a slight slouch — tilts the pelvis and flattens the natural curve of the lower back. That change increases pressure on the discs at L4–L5 and L5–S1. These discs are meant to absorb shock, but when they’re held in constant compression without movement, the load isn’t redistributed. Over time that can irritate nearby nerves and stabilizing muscles.
The problem isn’t sitting itself; it’s how long the spine stays compressed without changing position. Remember: sitting is a load-bearing posture for your spine, not a place to “rest” it.
Quick tips:
- Break up sitting every 30–45 minutes — stand, walk, or do gentle spinal movements
- Use lumbar support or a small cushion to maintain your natural curve
- Alternate between sitting and standing when possible
- Strengthen core and hip muscles to support spinal alignment
If you’ve been dealing with persistent low back pain or sciatica from prolonged sitting, feel free to book a consult — we can assess posture, movement patterns, and give targeted recommendations.
