Walking with your hands behind your back may seem like a simple and relaxed gesture, but according to psychology, it reveals much more than you think…

Compared to arms swinging or folded arms:

• Hands behind the back = low emotional expression
• Often seen in neutral or calm states
• Can indicate emotional restraint (not showing feelings openly)

However, this does NOT reliably indicate sadness, confidence, or dominance on its own.
