Polyvagal Theory

The Polyvagal Theory is a neurophysiological theory developed by Stephen Porges.

It describes how our autonomic nervous system constantly, largely unconsciously, evaluates whether we feel safe or unsafe, and how this evaluation influences our behavior, emotions, stress responses, and recovery.

A key insight of the polyvagal theory is that the parasympathetic nervous system does not consist of just one pathway, but two fundamentally different routes, each with a very different impact on health, connection, and recovery.

The Polyvagal Ladder: Three States of the Nervous System

Our nervous system continuously moves up and down through three states.
This is often illustrated as a ladder model.

1. Ventral Vagal State – Safety and Connection

Activated when we experience safety.

Characteristics:

• Social engagement and connection
• Curiosity and creativity
• Balanced heart rate and breathing
• Digestion, recovery, and immune system functioning optimally

This is the restorative state of the body. In this state we can learn, exercise sustainably, build relationships, and be ourselves.

2. Sympathetic State – Mobilization

This is the fight or flight response.

Characteristics:

• Stress, restlessness, rumination, anger, or urgency
• Energy directed toward the muscles rather than digestion
• Focus on action and survival

This state is functional during short-term stress, but becomes harmful when it remains active for long periods.

3. Dorsal Vagal State – Shutdown

This is the freeze or collapse response.

Characteristics:

• Emotional numbing or flattening
• Fatigue or dissociation
• Low energy and withdrawal

This is not relaxation, but a deep protective response of the nervous system.

Neuroception: Our Internal Safety Scanner

Our nervous system constantly and unconsciously scans both the environment and the body itself.

This process is called neuroception.

It continuously asks one question:
“Is it safe for me here?”

The nervous system evaluates signals such as:

• Facial expressions
• Tone and melody of voice
• Body posture and movement speed
• Internal signals such as heart rate, breathing, and gut sensations

Neuroception happens without conscious thinking. Trauma, chronic stress, or illness can disrupt this system and influence how safety, behavior, and recovery are regulated.

Safety as the Foundation for Recovery

True recovery is only possible when the body experiences safety.

Only then can the brain receive, process, and integrate information.

When working on health, it is essential to first bring the body into a state of safety.

How Do You Bring the Body into Safety?

Key factors include:

• A safe, non-judgmental environment
• Co-regulation: moving, sharing, and coaching together
• Warmth, both physical and emotional
• Genuine attention and feeling seen
• Breathwork and yoga

Co-regulation refers to the ability of our nervous system to calm, organize, and recover through interaction with another nervous system.

What Happens Physiologically?

When the ventral vagal system becomes active:

• The stress hormone cortisol decreases
• Breathing and heart rhythm stabilize
• Digestion resumes
• The brain becomes capable of learning, reflecting, and changing

Why Recovery Does Not Start with Thinking

A core principle of polyvagal theory is that safety is first experienced in the body. Only then can the brain participate.

The process works bottom-up:

1. Body and nervous system

2. Emotion

3. Thought and meaning

Recovery is not a mental decision, but a neurobiological state of safety.
When the body enters a calm state of being, the brain will follow.
