What is the fight or flight response

The fight or flight response is a physiological reaction as a response to events that could attack our survival.

Explanation:

Walter Bradford Cannon was the first person who described the term. His theory was related to animals and he established that animals reacted to attacks through the use of the sympathetic nervous system, which prepared them to fight or to escape.

There are some physiological changes with the existence of the fight or flight response. These changes' function is to give the body the necessary strength as well as speed to decide on fighting or escaping. These changes include the increasing in blood flow and blood pressure as well as the increasing of muscle tension.

The fight-or-flight response, also known as the acute stress response, refers to a physiological reaction that occurs in the presence of something that is terrifying, either mentally or physically. The response is triggered by the release of hormones that prepare your body to either stay and deal with a threat or to run away to safety.

The term 'fight-or-flight' represents the choices that our ancient ancestors had when faced with a danger in their environment. They could either fight or flee. In either case, the physiological and psychological response to stress prepares the body to react to the danger.
