4. Trauma is not
something that just lives on “in your head”: it’s deeply embedded in your
body.
Charles Darwin observed
similarities between the physical signs of emotion that humans and animals
alike exhibit. When a person sneers, for example, he exposes his canines,
much like a snarling dog. When a person feels threatened, the hair on the
back of the neck stands up, just like other mammals. Humans and mammals
naturally have a defensive posture, and Darwin attributed such similarities
to a shared evolutionary history.
In survival mode,
humans—like animals—will devote their emotional energies to fending off
enemies, real or imagined. This mindset, of course, leaves no room for love
(nor creativity, play, nor learning), which is why war veterans, for
example, have a difficult time connecting to the love and emotion that
their wives and children show.
Darwin saw clear links
between brain and body, and that deep emotions were not just “in the head”
but a conversation between brain, heart, and gut. Even in the mid-1800s, he
wrote of a “pneumogastric nerve,” which was central to the regulation and
expression of emotion, and interacted with the body’s viscera, or
intestines.
At a “gut level,” Darwin’s
intuition resonates. How often does deep grief or the pain of betrayal feel
like your heart is actually breaking or that you’ve been gut punched? Those
feelings are unbearable, and we are willing to do just about anything to
make them stop. We frantically cling to other people, numb ourselves with
drugs and alcohol, or cut ourselves open—all to distract ourselves from the
intense physical pain that the emotions bring.
Modern science is now
confirming Darwin’s insight that the brain and body are intimately
connected, and this discovery has tremendous implications for working with
the traumatized. In 1994, scientist Stephen Porges built on Darwin’s idea
of the pneumogastric nerve when he presented the idea of Polyvagal
Theory. The polyvagal nerve connects a variety of organs: the brain,
intestines, lungs, stomach, and heart. You can’t talk about the anatomy of
safety and danger without talking about the polyvagal nerve.
Social engagement is a sign
that the ventral vagal complex, or VVC, is in control: we smile when we see
others smiling; we nod to indicate we are tracking with our fellow
interlocutor, and our facial muscles convey concern when we hear sad news.
When the VVC is running the show, the heart rate slows, and breathing
becomes deeper. We feel safe and relaxed, open to intimacy. All is calm,
all is bright.
BUT whenever there’s a
threat to safety or social ties, the organs attached to the ventral vagal
complex begin to change: facial musculature shifts, vocal cords tighten,
breathing becomes labored, the tone of voice alters. If there’s no
assistance, the sympathetic nervous system takes over for the ventral vagal
complex, which strengthens muscles, heart, and lungs to fight or flee. If a
dog is in the room, it will usually start barking and snarling in response
to smelling people’s activated sweat glands.
If there’s no apparent
escape, the dorsal vagal complex (DVC) is engaged. This branches down into
the diaphragm, stomach, and intestines. Heart rate and metabolism slow. The
gut shuts down or expels—which is why people get “scared shitless.” Once
the DVC kicks in, the old reptilian brain is in control, and a person no
longer cares for others. Awareness, reason, and sometimes even sensitivity
to physical pain completely desert.
When we are in touch with
one another through the VVC, all is right with the world. We are attuned to
each other and the natural rhythms of life and community. This is hard to
restore for people who have experienced trauma. Immobilization lies at the
bottom of almost all traumatic experiences. Once your trauma is activated,
the DVC takes over and you collapse. You cannot encounter true intimacy and
belonging unless you can allow yourself to be immobilized and feel safe in
that immobilized state. Without it, intimate embrace, sleeping with a
partner, or enjoying sex will be impossible. The traumatized have a
difficult time figuring out when to have defenses up and when they can let
them down. This is why Cognitive Behavioral Therapy, which places an
emphasis on realigning beliefs with reality, is a superficial solution. It
engages the issues at a cognitive, conscious level, one that is impossible
for a survivor to access when the delicate equilibrium has been disrupted,
and biology has hijacked the reasoning parts of the brain in order to
survive a perceived threat.
The implications of the
body’s ties to trauma are profound: it changes the way we think about
trauma and the way we treat it. Chinese and Indian understandings of the
human person historically have been more holistic. The West is coming
around to appreciating the communication between body and mind.
