Detailed explanation-1: -Your body’s fight-flight-freeze response is triggered by psychological fears. It’s a built-in defense mechanism that causes physiological changes, like rapid heart rate and reduced perception of pain. This enables you to quickly protect yourself from a perceived threat.
Detailed explanation-2: -The fight, flight, or freeze response refers to involuntary physiological changes that happen in the body and mind when a person feels threatened. This response exists to keep people safe, preparing them to face, escape, or hide from danger.
