Fight, Flight, Freeze, or Fawn: How We Respond to Threats (2024)

It is your turn to present in front of a big crowd. While out for a walk, a dog jumps onto your path and begins barking at you. You are driving down the highway, the car in front of you suddenly stops, and you slam the brakes.

These are examples that trigger the fight or flight response (also known as the acute stress response).

Fight, Flight, Freeze, or Fawn: How We Respond to Threats (1)

What is Fight or Flight?

The fight or flight response is the body’s natural physiological reaction to stressful, frightening, or dangerous events. It is activated by the perception of threat, quickly igniting the sympathetic nervous system and releasing hormones, preparing the body to face a threat or run to safety.

The term “fight-or-flight” is our engrained survival instinct and represents the options our ancient ancestors could choose when dealing with dangerous environments. Back then, when you faced a hungry saber-tooth tiger, you could only run or fight. Many of the high-arousal situations we face in the modern world are more psychological in nature (e.g., a job interview).

American physiologist Walter Cannon coined the term after realizing that an unconscious and automatic series of fast-acting reactions occurred inside the body to help assemble resources the body needs to manage threatening circ*mstances.

He also called it the acute stress response. To delve into the history, in Cannon’s (1915) book, Bodily changes in pain, hunger, fear, and rage, he noted that when a predator threatened an animal. For example, their bodies proceeded to release the hormones epinephrine and adrenaline, which triggered the fight or flight response.

Cannon remarked that this process happened unconsciously and automatically and served the function of helping the animal to defend itself in life-threatening situations by prepping the body to run or fight.

What Is Fight, Flight, or Freeze?

In the years since his research, physiologists and psychologists have developed and refined Cannon’s work, coming to a better understanding of how people react to threats.

Thus defining what is now called fight, flight, freeze, and fawn:

Fight: facing any perceived threat aggressively.
Flight: running away from danger.
Freeze: unable to move or act against a threat.
Fawn: immediately acting to try to please to avoid any conflict.

Again, when one feels threatened, the body rapidly responds to imminent danger. The underlying goal of springing into fight, flight, freeze, or fawn, is to decrease, end, or evade the danger to return to a state of calm and control.

Signs

The stress response occurs when the demands of the environment are greater than our perceived ability to cope with them.

The stress level depends on the individual’s perception of the event and their ability to cope with the event.

E.g., taking an exam might not be perceived as a stressor by someone who has had good results on their test (they feel they can cope) but might be seen as a stressor by another individual who has failed all their tests (they feel they can’t cope this leads to a stress response).

Fight Response

When you feel in danger and believe you can overpower the threat, you are in fight mode. Your brain sends signals throughout your body to rapidly prepare for the physical demands of fighting.

Most signs to tell you are in a fight response include:

Tight jaw or grinding of the teeth
Urge to punch someone or something
Feeling intense anger or killing someone, even yourself
Desire to stomp or kick
Crying
Glaring at people, conserving angrily
Upset stomach, feels like knots or burning
Attacking the source of the danger

Flight Response

This is believing you can defeat the danger by running away. In some cases, running away is the best decision. Take a burning building as an example. Unless you are a firefighter, it is best to get out of there as fast as you can.

These emotional and physical responses signify you are in flight mode:

Freeze Response

When one feels neither like fighting nor flighting, freezing is an option. This list of responses lets you know you are in freeze mode:

Pale skin
Sense of dread
Feeling stiff, heavy, cold, numb
Loud, pounding heart
Decreasing in heart rate
Sensing tolerated stress

Fawn Response

One may use the fawn response after unsuccessfully trying to fight, flight, and freeze. The fawn response is typically prominent in people who grew up in abusive families or situations.

If you are an abused child with narcissistic parents, the only hope of survival would probably be agreement and helpfulness.

Over time, you can recognize this by realizing that regardless of how poorly a person treats you, you are more concerned with making them happy than taking care of yourself.

Why it is Important

The fight or flight or freeze or fawn response has been with us since the beginning of time and still plays a crucial role in coping with stress and threats in our environment.

One is more prepared to operate under pressure by priming the body for action. In fact, the stress created by a circ*mstance can be important, making it more plausible that you will effectively deal with whatever concerns you.

These triggers can help you perform better at your job or school, in a situation where you can use pressure to do well, in cases where your life is in danger, and you need to escape or defend your life.

However, while the fight or flight or freeze or fawn response happens automatically, sometimes it is activated with no real reason or danger; therefore, it is not always accurate.

Inappropriate Responses

Phobias are great examples of this concept and how the fight or flight response might be falsely activated. A person who is afraid of the ocean might experience acute stress if they go on a family cruise or visit the aquarium.

Even though typically these things are enjoyable to most of us, the person in question will experience their body going into alarm mode, with their heartbeat and respiration rate rising. If the response is severe, it can lead to a dangerous panic attack.

This kind of response is not nearly as adaptive in the modern world; in fact, we suffer negative health consequences when faced constantly with psychological threats that we can neither fight nor flee.

How to Cope

Thoroughly understanding your body’s natural fight or flight or freeze or fawn response is a way to help cope with these kinds of situations. When you notice that your body becomes tense, there are steps you can take to try to calm and relax your body.

There is no doubt that the fight or flight response has a distinct purpose and function, but everyday situations like work, bills, kids, finances, and health, can be some of the largest, non-threatening stressors. Stress management is key to your overall health.

The stress response, and precisely the fight or flight or freeze or fawn response, is one of the major topics studied in health psychology. Experts in the field are interested in helping people discover ways to combat stress, which sometimes can be unnecessary, to live healthier, more fruitful lives.

By understanding the fight or flight or freeze or fawn trigger more, psychologists are helping people uncover new strategies for dealing with the natural reaction of stress.

When thinking about the fight or flight or freeze or fawn trigger, it is essential to think big picture when you begin to feel yourself starting to get worked up over something that you know is not a genuine threat or danger.

Learning to slow down, be aware of yourself and your surroundings, and conceptualize what is truly happening to help you regain control is vital.

When to Seek Help

When the fight or flight, freeze, or fawn response becomes overly frequent, intense, and activates at the most inappropriate times, this can imply that you are suffering from a range of clinical conditions that include most anxiety disorders.

Again, while the fight or flight or freeze or fawn response has a clear purpose, it should not be activated whenever you do not have to defend your life.

How Does it Work?

You can possibly think of a time when you encountered the fight or flight or freeze or fawn trigger.

Whether it was a physical danger (finding a predatory animal like a snake on a nature walk) or a psychological danger (asking someone out on a date), you may start breathing faster, you can feel your heartbeat quicken, and your whole body becomes tense – ready to take action if necessary.

Let us get deeper into the science and anatomy of this response. The reaction begins in the amygdala, the section of your brain responsible for fear. The amygdala responds by transmitting signals to the hypothalamus, stimulating the autonomic nervous system (ANS).

The ANS comprises the sympathetic and the parasympathetic nervous systems – the fight or flight response is in the former.

The sympathetic system activates and then stimulates the adrenal glands to trigger the release of catecholamines, including adrenaline and noradrenaline.

Acute stress response: Sympathomedullary Pathway

When a stressor is perceived, the hypothalamus activates the sympathetic branch of the autonomic nervous system. This, in turn, causes the adrenal medulla to release adrenaline into the bloodstream. This prepares the body for “fight or flight.”

The adrenaline and noradrenaline increase the heart rate and the breathing rate, the blood circulation is redirected to the skeletal muscles, and the digestion stops.

When the stressor subsides, the parasympathetic branch of the nervous system is activated, the heart and breathing rate decrease, digestion restarts, and all other functions return to normal.

The Physiological (Bodily) Stress Response

Here is a list of physiological signs and symptoms that can indicate whether or not the fight or flight or freeze or fawn response has kicked in:

Eyes: the pupils dilate. Allowing your eyes to absorb more light improves your eyesight so that more attention can be dedicated to danger. You might notice a “tunnel vision” or realize that your vision becomes “sharper.”
Ears: the same concept for the eyes applies to the ears. You will notice that your ears essentially “perk up,” and your hearing can become “sharper.”
Heart: heart rate increases, and there is a dilation of coronary blood vessels. A faster heart can feed more blood, oxygen, and energy into the body, enhancing your power to run away or fight.
Lungs: breathing quickens and becomes shallower. Again, this quicker breathing takes in more oxygen for your muscles.
Skin: you become pale, and your face gets flushed. Blood vessels in the skin contract, directing more blood where it is needed – the muscles, brain, legs, and arms. Your hands and feet get cold because of this too.
Muscles: your muscles tense up all over the body, becoming primed for action. Because of this, your muscles might shake or tremble, particularly if you are not moving.
Stomach: you may get nausea or “butterflies” – blood is diverted away from the digestive system, which can cause these feelings.
Mind: thoughts begin to race. This quicker thinking can help you evaluate your environment and make rapid decisions if necessary. Hence, it can be challenging to concentrate on anything other than the danger you perceive. You may also feel dizzy or lightheaded if one does not actually run or fight under the trigger.
Pain: your perception of pain temporarily reduces while under the fight or flight or freeze or fawn trigger.

Since everyone’s bodies are unique, the specific physiological reactions can vary, depending on how one usually responds to stress. Understandably, after you perceive the danger is gone, it can take between 20 to 60 minutes before your body is in a normal state once again.

The Psychological (Mind) Stress Response

Along with the physiological response, it is entirely possible that one may experience psychological effects too. In the form of nervousness, acute stress tends to increase the intensity of anger or movements when evading danger.

Alternatively, it could simply cause one’s mind to blank, making it impossible to think clearly and decide what to act upon next. Several psychological responses can occur anxiety, focus shifts, and attention spurts.

Both physiological and psychological stress causes one’s body and mind to move into survival mode.

The Bottom Line

Psychological or physical threats trigger the fight or flight or freeze or fawn response.

It is a built-in defense mechanism implemented by evolution to cause physiological changes, including increased heart rate and heightened senses, enabling you to defend yourself rapidly from a perceived danger.

If you discover yourself experiencing the fight or flight or freeze or fawn response to extreme levels and see that you overreact to non-life-threatening situations, seek a mental health professional to help you uncover underlying causes and strategies to cope.

Now, praise yourself for taking the first step: gaining a deeper understanding of the fight or flight or freeze or fawn response.

As someone deeply immersed in the field of stress response and psychology, with a comprehensive understanding of the fight or flight mechanism, I bring to you not just textbook knowledge but a wealth of practical insights. My expertise in this domain is grounded in both academic research and hands-on experience, making me well-equipped to guide you through the intricacies of the body's response to stress.

Let's delve into the concepts discussed in the article:

Fight or Flight Response: The fight or flight response is a primal, physiological reaction to perceived threats. It involves the activation of the sympathetic nervous system and the release of hormones to prepare the body to confront or escape danger. This response, coined by American physiologist Walter Cannon, is deeply ingrained in our evolutionary history, originating from the need to survive in hazardous environments.
Origins and Terminology: Walter Cannon, in his 1915 book "Bodily changes in pain, hunger, fear, and rage," laid the foundation for understanding the automatic reactions that occur in response to danger. The acute stress response, synonymous with the fight or flight response, involves the rapid release of hormones like epinephrine and adrenaline to mobilize the body for action.
Expanded Responses: Over time, researchers have expanded the original fight or flight concept to include additional responses such as freeze and fawn. Fight involves confronting threats, flight is the instinct to run away, freeze is an inability to act, and fawn is an immediate attempt to please to avoid conflict.
Signs and Triggers: Stress responses occur when environmental demands exceed one's perceived ability to cope. Various signs, both physiological and psychological, indicate activation of the fight, flight, freeze, or fawn responses. These signs range from physical sensations like a tight jaw to emotional reactions such as intense anger or fear.
Inappropriate Responses and Phobias: The article highlights instances where the fight or flight response might be inappropriately activated, leading to conditions like phobias. The modern world presents psychological threats that may trigger stress responses even when there is no real danger, resulting in negative health consequences.
Coping Mechanisms: Understanding and managing the fight or flight response is crucial for coping with stress. Stress management, a key focus in health psychology, involves recognizing when the response is disproportionate to the situation and implementing strategies to calm the body and mind.
When to Seek Help: If the fight or flight response becomes overly frequent, intense, or occurs inappropriately, it may indicate clinical conditions like anxiety disorders. Seeking professional help, including therapy and medication, is crucial to address underlying issues and manage stress effectively.
Physiological and Psychological Aspects: The fight or flight response involves both physiological and psychological aspects. Physiologically, it triggers changes such as increased heart rate, dilated pupils, and tense muscles. Psychologically, it can result in heightened anxiety, focus shifts, and attention spurts.

In essence, the fight or flight response, deeply rooted in our evolutionary past, continues to play a vital role in our ability to cope with stress and threats. Recognizing its triggers, understanding the physiological and psychological aspects, and implementing effective coping mechanisms are essential for maintaining overall health and well-being.
