What is Polyvagal Theory?

Polyvagal Theory was created and developed by Dr. Stephen Porges (1994). It emphasises the role of the autonomic nervous system, especially the vagus nerve in regulating our health and behaviour. The theory describes the physiological and psychological states which underlie our daily behaviour as well as challenges related to our mental health and well-being.

Emotional regulation and stress reduction are cornerstone benefits of applying Stephen Porges theory. His approach offers a holistic method for understanding and influencing our physiological response to stress. Central to this is the vagus nerve which plays a key part in emotional responses and social engagement. Polyvagal exercises are therapeutic interventions which foster a deeper mind-body connection and improve responses to trauma.

The vagus nerve is the longest nerve in the body connecting the brain and major organs. Vagus means wandering in Latin as the nerve wanders around the body. The nerve regulates involuntary functions including blood pressure, and immune responses. It plays a vital role in the gut-brain axis which affects appetite. It also influences sensory and motor functions. This important nerve helps communication between the brain and organs influencing mood inflammation and stress recovery. This nerve helps individuals move from defensive states (fight/flight/freeze) to safe, social state by fostering neuroception – a subconscious detection of safety- using techniques to strengthen the vagus nerve.

Polyvagal therapy focuses on regulating the autonomic nervous system to treat trauma, anxiety , and stress. It moves survivors from fight/flight/freeze to a sense of safety and social engagement. Somatic awareness techniques, breath work, grounding exercises and safe connection, help to release trauma, reduce anxiety, and offer tools to manage panic and emotional shutdown.

Polyvagal Therapy and PTSD

The aim is to guide survivors out of chronic fight/flight/freeze back into a safe connection and promote long lasting improvement in trauma related symptoms. The benefits for survivors of PTSD are increased regulation using the tools, improved connection with others, and long-lasting relief.

Shame is also reduced as the survivor begins to understand that the symptoms are physiological reactions to trauma, not due to personal failures.

Key Techniques

·      Breathwork

·      Grounding Exercises

·      Somatic Awareness

·      Co-regulation

·      Acoustic Stimulation

·      Safe Movement

Polyvagal Therapy can allow individuals experiencing symptoms of anxiety, panic, PTSD, or depression a welcome sense of freedom. Healing the nervous system takes time and requires patience with the process. The good news is that the vagus nerve can be stimulated to move the individual out of an anxious and distressed state, into a calm, regulated state to help the nervous system to feel safe. Increased resilience and improved stress management leads to reduced symptoms of trauma and anxiety.

Polyvagal Therapy Techniques

This approach is holistic and offers a mind-body connection signalling safety to the brain. Polyvagal exercises and therapeutic support help to guide the client and their nervous system to feel safe again aiding trauma recovery. Therapy helps by mapping the nervous system and learning to identify personal triggers (that lead to stressful states) and ‘glimmers’ (that lead to safety).

 Breathing Techniques – slow, deep, and diaphragmatic breathing is a key technique for stimulating the vagus nerve to increase calm.

 Box Breathing is a simple and powerful exercise rooted in Polyvagal Theory. Box Breathing helps to regulate emotional responses and stimulate the vagus nerve. By consciously controlling the breath this promotes a sense of safety and can calm stress responses including flight responses.

Step 1. Breath in slowly through your nose for a count of four, filling your lungs with air.

Step 2. Hold your breath for four, allowing the oxygen to circulate.

Step 3. Exhale slowly through the mouth for four, emptying your lungs completely.

Step 4. Hold your breath again for four before taking another inhale.

Repeat the cycle for several minutes.

Grounding Techniques are the cornerstone of applying Polyvagal Theory to improve physiological responses and overall sense of safety and trauma recovery. The following exercise helps the connection with the senses and emphasises the importance of a mind-body link.

1.     Visual: Look around and name three objects you see.

2.     Auditory: Listen and identify three sounds you can hear.

3.     Olfactory: Notice any smells in the environment.

4.     Tactile: Touch various textures around you. Identify how each one feels.

5.     Gustatory: Taste or eat something and describe the flavours.

By engaging each sense individuals develop a deeper understanding and social engagement. This simple technique can recalibrate the body’s response to stress, aiding a restoration of a calm physiological state.

Somatic (Body -based) Awareness. These techniques focus on physical sensations to increase ‘vagal tone,’ which is a measure of the vagus nerve’s effectiveness in calming the body. Exercises encourage mindfulness of physical sensations and reactions during movement. This can help the individual to learn to calm their own nervous system. Mindful movement or Yoga can increase resilience and improve stress management.

Safe Haven Visualisation

This is an exercise based on Polyvagal Theory and it is designed to aid in creating a sense of safety and to promote a feeling of calm. The connection between the vagus nerve and the emotional response is thus stimulated.

Steps:

1.     Find a quiet and comfortable space.

2.     Close your eyes and take several deep breaths.

3.     Visualise a place where you feel at ease and safe.

4.     Pay attention to your haven (sights, sounds, smells, textures).

5.     Notice your body responds physiologically as you deepen into the visualisation. You may experience a calming of your stress response and an easing of tension.

6.     If your mind wanders, gently guide it back to your haven.

7.     Stay in this space for a few minutes, allowing a sense of safety to permeate throughout your body.

8.     Gradually bring your awareness back to the present moment.

9.     Open your eyes when you feel ready.

 The benefits of this simple exercise are that it promotes relaxation and stress reduction and enhances the mind-body connection. It supports trauma recovery by reinforcing a physiological sense of safety. Daily practice of the exercises can help to shift your body from stress responses like a flight response to a state of social engagement.

Polyvagal Theory emphasizes co-regulation, where our nervous systems synchronise with others to feel safe. Social connections are enhanced with improved ability feel safe in relationships. This is a key to trauma recovery and is a sign of emotional regulation.
