Desk work, smartphone browsing, and keyboard typing lock the chest into chronic flexion. As evening approaches, heavy constriction spreads to the base of the skull and behind the eyes.
Why Does Shoulder Massage Rebound So Quickly?
An adult head weighs approximately 5 to 6 kg. When it drifts forward by merely a few centimeters, gravitational leverage multiplies the mechanical load on the posterior cervical muscles up to 20 kg or more.
The real cause is not behind you, but the shortened myofascia of the anterior chest and arms pulling your frame forward. Releasing this front tension naturally restores your shoulders to their rightful structural axis.
