For other uses, see Fight or Flight. The fight-or-flight response (also called the fight, flight, freeze, or fawn response [in PTSD ], hyperarousal, or the acute stress response) is a physiological reaction that occurs in response to a perceived harmful event, attack, or threat to survival. It was first described by Walter Bradford Cannon.
The important thing to take away is that the fight or flight response is an automatic response. False alarms! Even though the fight or flight response is automatic, it isn't always accurate. In fact most of the time when the fight or flight response is triggered it is a false alarm-there is no threat to survival. The part of the brain the initiates the automatic part of the fight or flight response, the amygdala, can't distinguish between a real threat and a perceived threat. Chill, no, freeze! Sometimes the perceived threat is so intense it triggers a freeze response.
