The fight or flight response is an automatic physiological reaction to lớn an sự kiện that is perceived as stressful or frightening. The perception of threat activates the sympathetic nervous system và triggers an acute căng thẳng response that prepares the body toàn thân to lớn fight or flee. These responses are evolutionary adaptations to increase chances of survival in threatening situations. Overly frequent, intense, or inappropriate activation of the fight or flight response is implicated in a range of clinical conditions including most anxiety disorders. A helpful part of treatment for anxiety is an improved understanding of the purpose và function of the fight or flight response. This client information sheet describes the bodily consequences of the fight or flight response.

Description

Physiological responses

The fight or flight reaction is associated with activation of the sympathetic nervous system. The chain reaction brought about by the fight or flight response can result in the following physical effects:

Body SystemPhysiological effectConsequence
HeartIncreased heart rateDilation of coronary blood vesselsIncrease in blood flowIncreased availability of oxyren và energy lớn the heart
CirculationDilation of blood vessels serving musclesConstriction of blood vessels serving digestionIncreased availability of oxygene to lớn skeletal musclesBlood shunted to skeletal muscles và brain
LungsDilation of bronchiIncreased respiration rateIncreased availability of oxygen in blood
LiverIncreased conversion of glycoren to glucoseIncreased availability of glucose in skeletal muscle và brain cells
SkinSkin becomes pale or flushed as blood flow is reducedIncreased blood flow to muscles & away from non-essential parts of the body such as the periphery

Psychological responses

In addition lớn physiological reactions there is also a psychological component to lớn fight or flight response. Automatic reactions include a quickening of thought & an attentional focus on salient targets such as the source of the threat and potential avenues for escape. Secondary psychological responses can include appraisals about the meaning of the toàn thân reactions. For example, patients with panic disorder often misinterpret fight or flight responses as signs of impending catastrophe (“I’m having a heart attack”, “If this carries on I’ll go mad”).

History of the fight or flight response

The fight or flight response was originally described by American physiologist Walter Bradford Cannon in the book Bodily changes in pain, hunger, fear and rage (1915). He noted that when animals were threatened, by exposure to a predator for example, their bodies released the hooc môn adrenaline / epinephrine which would lead to a series of bodily changes including increased heart rate và respiration. The consequences of these changes are increases in the flow of oxyren và energy khổng lồ the muscles. Canon’s interpretation of this data was that there were emergency functions of these changes. He noted that they happened automatically và they served the function of helping the animal khổng lồ survive sầu threatening situations by readying the body for fighting or running.

A more modern understanding of the fight or flight response is reflected in the work of Schauer & Elbert (2010). Their more elaborated Model of physiological / psychological / behavioral responses to lớn threat is termed the ‘defense cascade’. They describe a series of stages which individuals exposed khổng lồ threat or trauma may go through, including: freeze, flight, fight, fright, flag, và faint.

Why the fight or flight response is important

The physiological responses associated with fight or flight can play a critical role in surviving truly threatening situations. However, many patients suffering from anxiety disorders or other conditions may have threat systems which have sầu become over-active, or which are insufficiently counterbalanced by activity in the parasympathetic nervous system.

Practically, many patients who suffer from anxiety will benefit from a deeper understanding of the fight or flight response. For example, patients with panic attacks or panic disorder often misinterpret the bodily signs associated with fight or flight as signs of impending catastrophe & understanding the fight or flight response is therefore a helpful ‘decatastrophizing’ technique. Similarly, patients with post-traumatic găng tay disorder (PTSD) may mistake the increased physiological arousal as an indicator that there is a genuine threat present: understanding more about the fight or flight response can help them to lớn feel safer, and to implement relaxation và grounding strategies.
