In life-threatening situations, our bodies respond in ways that aim to ensure our survival. Common survival responses are fight, flight, freeze, and fawn. 

Biological instincts within our autonomic nervous system, specifically the sympathetic nervous system, prepare us to confront, flee from, ignore, or appease a source that represents potential harm.

Do you have an overactive stress response?

For individuals who’ve experienced trauma, the associated neural pathways in our brains can become particularly sensitive to real or perceived threats. Such hyperawareness can lead to challenges in managing stress responses and potentially contribute to conditions like post-traumatic stress disorder (PTSD). 

In this article, we will explore what distinguishes the four prevalent stress responses from one another, their corresponding mental health implications, and how online therapy can help people control emotions in the face of stressors.                  

Understanding the acute stress response and its impact on the nervous system

The fight, flight, freeze, and fawn responses are part of our acute stress response. 

When faced with a threat, the body activates its sympathetic nervous system, releasing stress hormones like adrenaline and cortisol that prepare us to act quickly. To defend us from harm, this response is automatic and not within our conscious control.        

Fight response

The fight response activates when we perceive a threat we believe we can overcome. The body prepares for confrontation, often resulting in heightened alertness, increased heart rate, and focused attention. This response can serve us well in certain circumstances, but if triggered excessively or inappropriately, it can contribute to aggression, impulsivity, and challenges in our mental health.

For example, someone could tap you on the shoulder while riding in a packed subway car. Someone displaying the fight response may be primed for aggression, perceiving the threat as coming from someone who intends to harm. This response often stems from having experienced similar impactful moments associated with trauma, such as physical or sexual assault.

Flight response

The flight response occurs when we perceive a threat we believe we can escape by running away, often literally. Our bodies prepare for quick movement, which may cause increased heart rate, rapid breathing, and a rush of energy. Like the fight response, this can safeguard us in appropriate contexts but can lead to anxiety, restlessness, or avoidance behaviors when overactivated.

An appropriate flight response may look like coming across a snake and noticing it is coiled in a defensive position with its fangs bared. 

Many people would experience a quick engagement of the flight response and start backing away to avoid a potentially fatal bite. 

While a poisonous snake may be a legitimate reason to flee, our flight response may sometimes prompt us to run away when we might need to confront a challenge head-on. One example may be participating in a difficult conversation with a romantic partner and taking responsibility for a wrong-doing that will upset them.

Freeze response

While fight and flight are the two most commonly referenced stress responses, the freeze response may be just as common. In the freeze response, we perceive a threat but assess that neither fighting nor fleeing may be an option. This response can be akin to “playing dead” to make us less noticeable to the threat. 

Physically, the freeze response may involve reduced movement and slowed breathing. When frequently activated, especially in response to past trauma, the freeze response can contribute to feelings of paralysis, difficulty making decisions, and depressive symptoms.

Fawn response

The fawn response may be triggered when we perceive a threat we believe we can appease or placate. It involves behaviors aimed at pleasing others, defusing conflict, or seeking approval. 

While this can be adaptive in certain circumstances, chronic activation can lead to behaviors such as people-pleasing, difficulty setting boundaries, and low self-esteem.

Fawning may look like childhood trauma where a child does everything to appease an angry parent as a way to avoid their lashouts and “survive” in their environment. This behavior may translate to adulthood, where pleasing others becomes a coping mechanism to avoid the anger, disappointment, or rejection of others. 

In a workplace scenario, an employee might fawn in front of an intimidating supervisor to avoid toxic behaviors such as public shaming or unfair treatment.

Understanding the stress response of fight, flight, freeze, or fawn and its mental health implications

Chronic activation of any of these stress responses can lead to mental health conditions. For instance, chronic fight or flight responses can contribute to anxiety disorders, while a frequent freeze response may be associated with depression. Fawning, if overused, can lead to relational difficulties and low self-esteem.

The acute stress response system can become significantly dysregulated in individuals who’ve experienced significant trauma. These individuals may respond with fight, flight, freeze, or fawn responses in situations that aren’t genuinely threatening. This quickness to enter the fight, flight, freeze, or fawn response can often be seen in PTSD, where reminders of past trauma can trigger these survival responses, leading to significant distress and impairment.
