What Is Fight Or Flight Hormone?

It is a hormone in a fight-or-flight response(or acute stress response).  Adrenaline is the body’s activator and is released in response to anxiety, exercise, or fear. This is the basis of the so-called ‘fight-or-flight‘ reaction. This response is a physiological reaction occurring in a dreadful event either physically or mentally and is triggered through the hormone-release preparing the body to either hold on or deal with a threat or run towards safety.

In the event of acute-stress, the sympathetic nervous system of the body is activated as a result of a sudden release of hormones which trigger the adrenal glands causing the release of catecholamines. This leads to an increase in the blood pressure, heart rate and rate of breathing. It takes close to 20-60 minutes for the body to get back to normal functioning after such an event.
