Why Sitting in a Chair Is Slowly Rewiring YOUR SPINE — The Science Nobody Talks About

You sit down, let your shoulders drop, and it feels like rest. But your nervous system is currently hiding something from you. What is physically happening inside your back in that exact moment is not recovery. It is a slow, silent structural response to a set of mechanical instructions you don't even know you are sending. By the time you stand up and feel that brief moment of stiffness, the physics of your body have already changed. This is the hidden mechanics of a position you spend thousands of hours in every year.
