How the nervous system links emotion to physical sensation

Have you ever felt your heart race before an important meeting, noticed a knot in your stomach during an argument, or experienced tight shoulders after a stressful day.

These sensations aren’t imagined. They’re real, measurable, and deeply rooted in the biology of your nervous system.

Emotion isn’t confined to your mind. It’s a whole-body experience. Every feeling you have is accompanied by a cascade of physiological changes involving your brain, autonomic nervous system, muscles, heart, lungs, and internal organs. This constant dialogue between body and brain shapes how you experience both emotion and physical sensation.
