Three core concepts of PVT include neuroception, hierarchy, and co-regulation. Neuroception is how our nervous systems protect us by constantly scanning the environment for signs of safety, danger, and life threat. Though neuroception occurs unconsciously, it can be brought into consciousness through mindfulness practices that hone interoception and bodily attunement.
Hierarchy refers to the three states of the autonomic nervous system; they exist like a ladder with dorsal vagal at the bottom, sympathetic in the middle, and ventral vagal at the top. As you move from bottom to top, you travel from the oldest iteration of the nervous system to its most recent evolution.
Dorsal vagal, the oldest part of the nervous system, shuts down or becomes immobilized when faced with a life threat. You might envision an opossum playing dead when she senses a predator, or you might imagine going into energy conservation mode. Dorsal is associated with feelings of collapse, withdrawal, sleepiness, and low energy.
In contrast to the immobilization of the dorsal vagal state, the sympathetic nervous system protects us through mobilization into what is commonly referred to as fight or flight. This means that when feeling unsafe, the body unconsciously shifts into the mode of running away from the threat or of fighting for survival. There can be two distinct channels of the sympathetic nervous system: one associated with anxiety and the other with anger. Being in the sympathetic state can feel racy, stressed, restless, jittery, and explosive.
Ventral vagal, the top of the polyvagal hierarchy, is the most recent iteration of the autonomic nervous system. The ventral vagal state recognizes that it is belonging to a group and connecting with others that protects us. We became pack animals who existed in community with others. Ventral feels calm, curious, and engaged.
The power of becoming familiar with your three states is recognizing them when you are there, understanding what triggers you into the dysregulated states of dorsal and sympathetic, and learning what brings you out of those dysregulated states and into the regulated ventral state. These skills can be particularly useful when dealing with the dysregulating aspects of diet culture and understanding what role food plays in nervous system regulation.
In addition to neuroception and the autonomic hierarchy, the final core concept within PVT is co-regulation. This refers to the ways in which our nervous systems interact and either regulate one another – help them anchor into that safely connected state of ventral vagal – or dysregulate one another, triggering them into a sympathetic or dorsal state. This is part of the power of working with an individual or a group in healing your relationship with food and body.
Becoming Familiar with Your States
The first stage in becoming familiar with your own autonomic hierarchy is characterizing the physical and emotional experience of being in each of the three states. This allows you to notice and name where you are in real time or reflect on certain situations and identify what was going on in your nervous system. Here is an exercise to help you begin this exploration. As an example, the following describes my own embodied experience of my three states:
Physical sensations: Open sensation in chest, no tension in the jaw, abdomen relaxed, facial muscles relaxed, body feels relaxed
Emotional experience: Interested in my experience and in others’ experience, content and satisfied, able to work with difficulty, open to feeling, a sense of flow, a feeling of engagement with the world, life feels “workable,” the feeling of being squarely in my own life
SympatheticPhysical sensations: Muscle tension, tightness in chest and throat, knot in the stomach, buzzy sensation in lips and upper arms, neck painEmotional experience: feeling overwhelmed, feeling trapped, thinking speeds up, can’t make sense of my thoughts, lost perspective, no distinction between irritants and catastrophes
Physical sensations: Sleepy, body feels heavy and wooden, sensation of caving into myself
Emotional experience: Shame, feeling alienated from others, feeling “cursed,” wanting to disappear
As you become familiar with your states, practice noticing and naming them and start to connect the dots between state and what seems to have contributed to your arriving there.
While PVT has its critics, it does provide a useful lens through which to examine our relationship with food and our bodies. Based on your state, your appetite, cravings, and uses of food may differ significantly. As you recognize the different states that you move through, how is your relationship with food different?
You can explore your own relationship with food through the polyvagal lens with this handout exclusively for Professional Members. When I contemplate my own relationship with food in ventral, sympathetic, and dorsal states, this is what I have discovered:
Ventral: appetite regulated, eating feels coordinated with physical hunger, craving a variety of foods
Sympathetic: may feel nauseated, the appetite may be disrupted or absent, craving crunchy textures like Inca corn
Dorsal: appetite may be disrupted or absent, craving soups and creamy foods, eating feels like seeking soothing and comfort
A key point in approaching PVT with mindfulness is how important it is to practice self-compassion. When you realize that your nervous system is acting to protect you at all times, it becomes easier to be kind to yourself, to forgive yourself, and to begin to make new choices. And by identifying how your nervous system state influences your relationship with food, you begin to understand exactly how your nervous system is seeking safety so that you can ultimately add to your coping skills.
This is not about taking away food as a means of soothing a dysregulated nervous system. Eating the foods that help to regulate you should be seen as evidence of your body’s intelligence. In addition to that tool, however, it is so useful and compassionate to have other outlets, supports, and resources.
