Polyvagal Theory: Understanding Your Nervous System Responses
Polyvagal Theory, Have you ever wondered why your body sometimes reacts before your conscious mind has time to understand what is happening?
Your heart may begin racing. Your muscles may tense. You might suddenly feel the urge to escape, defend yourself, disconnect, or completely shut down.
These reactions can feel confusing—especially when the present situation does not appear to match the intensity of the response.
Understanding the nervous system may help us become more curious about these reactions instead of immediately judging ourselves for having them.
One framework used to explore these responses is Polyvagal Theory.
What Is Polyvagal Theory?
Polyvagal Theory was introduced by neuroscientist Stephen Porges as a framework for understanding how the autonomic nervous system relates to safety, threat, connection, and defensive responses.
In popular discussions of the theory, three broad states are commonly described:
Ventral vagal — safety and connection
Sympathetic — mobilization, including fight or flight
Dorsal vagal — immobilization or shutdown
These concepts can provide a useful language for exploring our internal experiences, although human nervous-system functioning is complex and should not be reduced to three simple boxes.
Ventral Vagal: Safety and Connection
The ventral vagal state is commonly associated with feelings of safety, social connection, engagement, and
When we feel sufficiently safe, we may find it easier to communicate, connect with others, think clearly, remain curious, and respond to challenges without immediately entering a defensive state.
This does not mean life is perfect or that we never experience difficult emotions.
It means our system may have enough sense of safety to remain engaged with what is happening.
Sympathetic Activation: Fight or Flight
When the nervous system perceives a threat, the body may prepare for action.
This can include an increased heart rate, rapid breathing, muscle tension, restlessness, anger, anxiety, or a strong desire to escape.
The sympathetic nervous system plays an essential role in helping us respond to challenges and danger.
The difficulty can arise when the body continues responding as though danger is present even after the immediate threat has passed.
For someone with a history of overwhelming experiences, certain sounds, behaviors, situations, or relationship dynamics may trigger a powerful response before the conscious mind fully understands why.
Dorsal Vagal: Shutdown and Immobilization
When fighting or escaping does not feel possible, some people may experience forms of immobilization or shutdown.
A person may feel disconnected, numb, exhausted, withdrawn, or unable to respond.
From the outside, this can sometimes be mistaken for laziness or a lack of caring.
Understanding nervous-system responses invites us to ask a different question:
Instead of asking, “What is wrong with me?” what happens when we become curious about what our body may be responding to?
The Connection Between Childhood Trauma and the Nervous System
This is where Tuesday and Thursday’s conversations connect.
On Tuesday, we explore childhood trauma and the patterns that early experiences can create.
On Thursday, we move deeper into a conversation about what may happen within the nervous system when a person perceives safety or threat.
A childhood spent navigating instability, fear, emotional neglect, or unpredictable environments may influence patterns that continue into adulthood.
This does not mean every emotional reaction is caused by childhood trauma, nor does understanding the nervous system replace professional assessment or treatment when needed.
It does, however, give us another lens through which we can explore ourselves.
Awareness Can Create New Choices
We cannot always control our body’s first automatic response.
We can, however, learn to recognize patterns.
We can notice when our body becomes activated. We can become aware of what helps us feel grounded and connected. We can learn what environments, relationships, and practices support a greater sense of safety.
Awareness creates an opportunity to respond differently.
And sometimes understanding why our body responds the way it does can change the relationship we have with ourselves.

This Thursday, The People’s Podcast continues our exploration of trauma and healing with:
POLYVAGAL THEORY: Ventral Vagal, Sympathetic & Dorsal Vagal
We will explore nervous-system responses, safety, connection, fight or flight, shutdown, and how understanding our internal patterns may help us develop greater self-awareness.
