The Fight-or-Flight Response: Understanding Its Role in Survival and Stress Management

Introduction

The fight-or-flight response is a physiological and psychological reaction that occurs in response to perceived threats or stressors. This biological mechanism, first described by physiologist Walter Cannon in the early 20th century, equips organisms with the ability to either confront or flee from danger. The purpose of this report is to explore the intricacies of the fight-or-flight response, including its biological underpinnings, historical significance, and implications for modern stress management. By examining the response through an interdisciplinary lens that incorporates biology, psychology, and sociology, we can better understand its critical role in survival and its relevance in contemporary life.

The Biological Mechanism of the Fight-or-Flight Response

At its core, the fight-or-flight response is driven by the body’s autonomic nervous system, specifically the sympathetic nervous system. When an individual perceives a threat, the hypothalamus activates the sympathetic nervous system, leading to the release of catecholamines—primarily adrenaline (epinephrine) and norepinephrine—from the adrenal medulla. These hormone
