Why Does Sitting Cause Back Pain? (Simple Fix That Works)

Sitting causes back pain because it weakens your core and tightens your hips.

Here is what happens in your body when you sit too long:

When you sit for long periods:

- your hip flexors shorten

- your lower back compensates

- your posture collapses

The main reason is simple: your body is not designed to stay in a seated position for long periods.

This leads to stress on the spine.

To fix this:

- stand up every 30 minutes

- stretch your hips

- maintain a neutral spine

Small changes reduce pain quickly.
