Understanding the Freeze Response: Mechanisms and Implications in Stress Reactions

Introduction The freeze response is a critical aspect of the human stress response, often overshadowed by the more commonly discussed fight-or-flight mechanisms. This report aims to elucidate the physiological and psychological mechanisms underlying the freeze response, its evolutionary significance, and its implications in contemporary stress reactions. By examining the neurobiological pathways activated during the freeze response and its potential effects on mental health, the report seeks to provide a comprehensive understanding of this complex phenomenon.

The Freeze Response: Mechanisms at Play The freeze response, also referred to as the “immobility response,” is one of the three primary responses to perceived threats, alongside fight and flight. The physiological basis of the freeze response involves a cascade of hormonal and neural changes initiated by the autonomic nervous system. When faced with a threat, the body first activates the sympathetic nervous system, leading to the release of stress hormones such as adrenaline and cortisol. In the case of extreme or ove
