Getting Unstuck from PTSD
One of the painful repercussions of Post Traumatic Stress Disorder (PTSD) is the experience of a lack of control that can occur when you feel trapped by feelings of anxiety, panic, overwhelm, or despair. Polyvagal theory, the work of Stephen Porges, M.D., offers a valuable framework for understanding and effectively responding to the intense emotional and physiological symptoms of PTSD.
“Healing the nervous system can take time and requires patience. Put the polyvagal theory into action in you life to increase your sense of freedom in body and mind” -Dr. Arielle Schwartz
The Nervous System: A Basic Model
A basic model of the nervous system shows that we have two components of our nervous system, one that is under our conscious control (e.g. moving your hand) and another that functions without our awareness (e.g. regulating our body temperature). The portion of the nervous system that functions without our conscious awareness is called the autonomic nervous system (ANS). All of our emotional expressions are mediated by the ANS as it either mobilizes energy through our sympathetic nervous system or conserves energy through our parasympathetic nervous system.
- The sympathetic nervous system is associated with the fight or flight response and the release of cortisol (stress chemicals) throughout the bloodstream.
- The parasympathetic is associated with relaxation, digestion, and regeneration.
The sympathetic and parasympathetic nervous systems are meant to work in a rhythmic alternation that supports healthy digestion, sleep, and immune system functioning.
The Polyvagal Theory
Research by Dr. Stephen Porges offers an advanced understanding of the ANS, especially as related to trauma and PTSD. The autonomic nervous system is regulated by the vagus nerve or the tenth cranial nerve. The vagus nerve connects the brain to major systems in the body including the stomach, gut, heart, lungs, throat, and facial muscles. Broadly speaking, the vagus nerve has an inhibitory influence upon the heart and sympathetic nervous system activity. Dr. Porges uses a metaphor suggesting that the vagus nerve is like pressing pressing the brake pedal when driving a car. Removal of the parasympathetic “vagal brake” causes an increase in heart rate and greater vulnerability to stress.
The “ventral vagal complex” (VVC) also referred to as the “social nervous system” is a branch of the vagus nerve that functions as a refined brake which has a calming and soothing effected reflected in rhythmic oscillations in heart rate variability. From an evolutionary perspective, the social nervous system has evolved most recently.
When there is stress or any experience of threat (real or perceived), we will rely upon our VVC or social nervous system first to re-establish a sense of connection and safety. For example, “tend and befriend” behaviors are a stress response that attempts to re-establish a safe relational bond. However, if the social nervous system fails to resolve stress, we will progressively resort to evolutionarily older strategies. Next, we will draw upon sympathetic nervous system actions such as fight or flight to mobilize us into self-protection.
If the sympathetic nervous system is unsuccessful in re-estabilishing safety, we will default to the evolutionarily oldest part of the vagus nerve, the “dorsal vagal complex” (DVC). This more primitive strategy engages the parasympathetic nervous system in an unrefined manner which Porges refers to as an abrupt vagal brake. Here, the parasympathetic nervous system engages immobilizing defensive actions such as fainting, feigned death, or dissociation.
Importantly, both the dorsal vagal complex (DVC) an the ventral vagal complex (VVC) will exert inhibition on the sympathetic nervous system; however, the DVC can have serious repercussions on mental and physical health. On the other hand, the VVC is associated with increases in health and emotional wellbeing.
Our natural state of rest and safety allows us to engage our social nervous system (VVC) facilitating our ability to connect to others, feel playful, feel love, and relax into connection. You know that you are engaging the social nervous system when you are able to recognize when you are safe, be self-reflective, feel a warmth in your smile, and the sparkle in your eyes. Your social nervous system increases your ability to respond effectively when you feel keyed up with anxiety or shut-down with depression.
Furthermore, your social nervous system (VVC) is strengthened by myelination. Myelination is a fatty coating on nerve pathways that is increased through repeated use and results in increased speed and control. You can imagine here the myelination that occurs in the learning of a new piece of music for the piano. Initially notes are played slowly and carefully but with repeated practice you begin to create music, eventually without reading the music at all. Likewise, the pathways of the social nervous system are strengthened through repeated practice.
Whether you are feeling anxiety depression you can use tools to engage your social nervous system to re-establish higher order nervous system functions. For example, if you are experiencing anxiety you are likely in fight or flight, a key defense reaction of sympathetic nervous system. Sympathetic actions involve mobilization; the need to move your body to release the build of stress cortisols. You can engage your social nervous by rubbing your hands together vigorously and making physical contact to your own face, neck, upper chest, arms, and legs. You can also explore physical movements that feel safe and grounding such as going for a walk or shaking your arms and legs to release stress. When we feel safe we can engage our social nervous system to use the energy of the sympathetic nervous system to dance, play, and laugh.
Feeling shut down, collapsed, depressed, or numb is an indication that you are in the defensive reactions of your parasympathetic nervous system which is characterized by immobilization. If you have a history of trauma it is possible that you are perceiving threats in your environment that are not actually occurring in the here and now. This is because a common symptom of PTSD is confusion between the past and the present. In this case, your social nervous system can help you find clues that help you recognize that you are not in imminent danger now which helps you access the positive, relaxing elements of your parasympathetic nervous system of “rest and digest.” When possible, turn towards a loving connection with a friend, caring partner, or a pet. If you are able, make eye contact or call someone you trust and listen to the sound of their voice. You can also visualize a loving animal, friend, or protective ally to restore a felt sense of connection. When we can embrace immobilization with safety we can access the nourishment of the relaxation response.
Implications for Healing PTSD
The polyvagal theory in action can allow you to increase your sense of freedom in body and mind when experiencing symptoms of anxiety, panic, or depression. Here are some suggestions:
- Focus on the present moment
- Engage the sense of smell with an essential oil that brings a positive association or feeling
- Re-establish connection by calling a friend, snuggling with your pet, or loving self touch.
- Express feelings through talking, writing, drawing, movement
- Focus on your breath as a fine tuning mechanism to regulate the nervous system
- Engage in a mindfulness practice such as meditation or therapeutic yoga
- Allow yourself to play or get creative
- Focus on the good by tuning into the beauty around you
Therapeutic implications of Polyvagal Theory inform Somatic psychology and EMDR Therapy. Healing the nervous system can take time and requires patience with the process and with yourself. You are not failing when you feel anxious or depressed. You are also not alone. Put the polyvagal theory into action in you life to increase your sense of freedom in body and mind Further Reading:
