The fight or flight response, also known as the “acute stress response” was first described by Walter Cannon in the 1920s as a theory that animals react to threats when the autonomic nervous system reacts. His theory was later recognized as the first stage of a general adaptation syndrome that regulates stress responses among vertebrates and other organisms.
Our autonomic nervous system consists of two branches: the parasympathetic and the sympathetic systems. The sympathetic system’s general action is to control the body’s response during perceived threat. Whereas, the parasympathetic system’s general action is to control the body’s response while at rest. The sympathetic system has very short neurons and the system is faster which causes
