Understanding The Fight & Flight Response When You Are Under Stress

Fight and flight response are also recognised as the acute stress response and is often described as the physiological reaction that happens in a frightening and terrifying situation or condition. In simple terms, it is referred to as the response of body during any danger, threat or fear. During any terrifying condition, certain hormones are released in the body which helps in triggering the fight and flight response.  These hormones work together to formulate your response (to stay and fight or to run away) in the course of any disturbing and scary situation.

An American physiologist Walter Cannon first defined the theory of fight-or-flight response in the 1920s. Cannon comprehended and explained, “A chain of rapidly occurring reactions inside the body helped to mobilize the body’s resources to deal with threatening circumstances which are known as the stress response”.

When the situation gets normal, a relaxation response is activated in the body which approximately takes 20-60 minutes to make the body systems comes down to function normally.

The fight-or-flight response can also occur during the about to happen physical danger. For example, facing a big and barking dog while passing through a way or preparing for a staging performance and presentation in front of thousands of people.
