Polyvagal Theory Therapy in Portsmouth, NH: Understanding Your Nervous System's Response to Stress, Anxiety, and Trauma

Have you ever wondered why your body reacts so strongly to stress even when you know you're safe? Why certain situations trigger anxiety, overwhelm, emotional shutdown, or physical symptoms that seem difficult to control?

​

Many people assume these responses are simply emotional reactions or signs of weakness. In reality, they are often rooted in the nervous system's automatic survival responses.

​

Polyvagal Theory offers a powerful framework for understanding how the nervous system influences our thoughts, emotions, behaviors, relationships, and overall sense of safety. At Authentically You Counseling in Portsmouth, NH, Jayme Sullivan incorporates Polyvagal Theory-informed approaches to help clients better understand their nervous systems, build emotional regulation skills, and move toward healing and resilience.

​

What Is Polyvagal Theory?

Polyvagal Theory was developed by Dr. Stephen Porges and provides a deeper understanding of how the autonomic nervous system responds to safety, connection, stress, and perceived danger.

​

Rather than viewing the nervous system as simply switching between "fight or flight" and "rest and digest," Polyvagal Theory explains that the body constantly scans the environment for cues of safety or danger. This process occurs largely outside of conscious awareness and influences how we feel, think, and interact with others.

The theory helps explain why people may experience anxiety, panic, emotional shutdown, chronic stress, trauma responses, relationship difficulties, or physical symptoms even when no immediate danger is present.

​

Understanding the Three Nervous System States

According to Polyvagal Theory, the nervous system moves between three primary states.

​

Ventral Vagal State: Safety and Connection

This is the state where we feel most grounded, connected, and emotionally regulated.

​

When operating from a ventral vagal state, individuals often feel:

​

• Calm and present

• Emotionally balanced

• Connected to others

• Curious and engaged

• Able to solve problems effectively

• Safe in relationships

 

This is the state where learning, healing, and meaningful connection are most likely to occur.

​

Sympathetic State: Fight or Flight

When the nervous system detects danger or threat, it may shift into a sympathetic state.

​

Common experiences include:

​

• Anxiety

• Racing thoughts

• Hypervigilance

• Restlessness

• Irritability

• Panic symptoms

• Muscle tension

• Difficulty relaxing

 

For many individuals struggling with anxiety disorders, panic attacks, or chronic stress, the nervous system becomes stuck in a prolonged fight-or-flight response.

​

Dorsal Vagal State: Shutdown and Disconnection

When the nervous system becomes overwhelmed and perceives that fighting or escaping is not possible, it may enter a dorsal vagal state.

​

Individuals may experience:

​

• Emotional numbness

• Fatigue

• Withdrawal

• Hopelessness

• Low motivation

• Depression

• Disconnection from others

 

This state can often appear in individuals who have experienced trauma, chronic stress, burnout, or prolonged emotional overwhelm.

​

How Trauma Affects the Nervous System

Trauma impacts more than memories. It changes how the nervous system responds to the world.

​

After a traumatic experience, the nervous system may continue to behave as though danger is still present, even when circumstances have changed. This can lead to ongoing symptoms such as:

​

• Anxiety

• Hypervigilance

• Difficulty trusting others

• Panic attacks

• Emotional reactivity

• Sleep disturbances

• Chronic stress

• Feelings of being unsafe

 

Many people find relief simply by understanding that these reactions are not character flaws but protective responses created by the nervous system.

​

Polyvagal Theory and Anxiety

Anxiety is often experienced physically before it is experienced mentally.

​

Individuals struggling with anxiety may notice:

​

• Racing heart

• Tight chest

• Shallow breathing

• Digestive discomfort

• Difficulty concentrating

• Feeling constantly "on edge"

 

Polyvagal Theory helps explain that these symptoms may reflect a nervous system that is operating in a state of perceived danger, even when no actual threat exists.

​

Understanding this connection often helps reduce self-judgment and opens the door to more effective coping strategies.

​

Polyvagal Theory and Depression

Many individuals experiencing depression describe feeling emotionally numb, disconnected, exhausted, or shut down.

​

From a Polyvagal perspective, these experiences may reflect a nervous system that has entered a protective shutdown state after prolonged stress, overwhelm, trauma, or emotional exhaustion.

​

This perspective can be incredibly validating because it shifts the conversation away from self-blame and toward understanding how the body is attempting to protect itself.

​

Polyvagal Theory and Chronic Pain

Emerging research continues to explore the connection between the nervous system and chronic pain.

For some individuals, chronic pain may persist even after physical healing has occurred. This can happen when the nervous system remains highly sensitized and continues sending danger signals throughout the body.

​

Polyvagal Theory shares important connections with approaches such as Pain Reprocessing Therapy (PRT), which helps individuals understand how the brain and nervous system can contribute to persistent pain experiences.

​

How Polyvagal Theory Is Used in Therapy

Polyvagal Theory does not replace traditional therapy approaches. Instead, it provides a framework that helps therapists and clients better understand emotional and physiological responses.

​

At Authentically You Counseling, Polyvagal Theory-informed therapy may help clients:

​

• Understand their nervous system patterns

• Identify triggers and stress responses

• Increase emotional regulation

• Build resilience

• Improve self-awareness

• Develop healthier coping strategies

• Strengthen relationships

• Reduce anxiety and overwhelm

• Feel safer within their own bodies

 

The goal is not to eliminate stress entirely but to increase flexibility and the ability to return to a state of safety and connection more easily.
