what is a flight response
The Fight or Flight response is a physiological response triggered when we feel a strong emotion like fear. Fear is the normal emotion to feel in response to a danger or threat. Fear also has a close relative we call anxiety. The Fight or Flight response evolved to enable us to react with appropriate actions: to run away, to fight, or sometimes freeze to be a less visible target. So it is important to think of this as a normal response, but one which can be triggered too often, by things which we perceive to be a threat to us.
