The Body Keeps the Score: Brain, Mind, and Body in the Healing of Trauma

by Bessel van der Kolk

Semrad taught us that most human suffering is related to love and loss and that the job of therapists is to help people “acknowledge, experience, and bear” the reality of life—with all its pleasures and heartbreak. “The greatest

sources of our suffering are the lies we tell ourselves,” he’d say, urging us to be honest with ourselves about every facet of our experience. He often said that people can never get better without knowing what they know and feeling what they feel.

Healing, he told us, depends on experiential knowledge: You can be fully in charge of your life only if you can acknowledge the reality of your body, in all its visceral dimensions.

Trauma by nature drives us to the edge of comprehension, cutting us off from language based on common experience or an imaginable past.

No matter how much insight and understanding we develop, the rational brain is basically impotent to talk the emotional brain out of its own reality. I am continually impressed by how difficult it is for people who have gone through the unspeakable to convey the essence of their experience. It is so much easier for them to talk about what has been done to them—to tell a story of victimization and revenge—than to notice, feel, and put into words the reality of their internal experience.

Being traumatized means continuing to organize your life as if the trauma were still going on—unchanged and immutable—as every new encounter or event is contaminated by the past.

After trauma the world is experienced with a different nervous system. The survivor’s energy now becomes focused on suppressing inner chaos, at the expense of spontaneous involvement in their life. These attempts to maintain control over unbearable physiological reactions can result in a whole range of physical symptoms, including fibromyalgia, chronic fatigue, and other autoimmune diseases. This explains why it is critical for trauma treatment to engage the entire organism, body, mind, and brain.

The most important job of the brain is to ensure our survival, even under the most miserable conditions. Everything else is secondary. In order to do that, brains need to: (1) generate internal signals that register what our bodies need, such as food, rest, protection, sex, and shelter; (2) create a map of the world to point us where to go to satisfy those needs; (3) generate the necessary energy and actions to get us there; (4) warn us of dangers and opportunities along the way; and (5) adjust our actions based on the requirements of the moment.4

The Polyvagal Theory provided us with a more sophisticated understanding of the biology of safety and danger, one based on the subtle interplay between the visceral experiences of our own bodies and the voices and faces of the people around us. It explained why a kind face or a soothing tone of voice can dramatically alter the way we feel. It clarified why knowing that we are seen and heard by the important people in our lives can make us feel calm and safe, and why being ignored or dismissed can precipitate rage reactions or mental collapse. It helped us understand why focused attunement with another person can shift us out of disorganized and fearful states.

Our culture teaches us to focus on personal uniqueness, but at a deeper level we barely exist as individual organisms. Our brains are built to help us function as members of a tribe. We are part of that tribe even when we are by ourselves, whether listening to music (that other people created), watching a basketball game on television (our own muscles tensing as the players run and jump), or preparing a spreadsheet for a sales meeting (anticipating the boss’s reactions). Most of our energy is devoted to connecting with others.

If we look beyond the list of specific symptoms that entail formal psychiatric diagnoses, we find that almost all mental suffering involves either trouble in creating workable and satisfying relationships or difficulties in regulating arousal (as in the case of habitually becoming enraged, shut down, overexcited, or disorganized). Usually it’s a combination of both. The standard medical focus on trying to discover the right drug to treat a particular “disorder” tends to distract us from grappling with how our problems interfere with our functioning as members of our tribe.

Being able to feel safe with other people is probably the single most important aspect of mental health; safe connections are fundamental to meaningful and satisfying lives. Numerous studies of disaster response around the globe have shown that social support is the most powerful protection against becoming overwhelmed by stress and trauma. Social support is not the same as merely being in the presence of others. The critical issue is reciprocity: being truly heard and seen by the people around us, feeling that we are held in someone else’s mind and heart. For our physiology to calm down, heal, and grow we need a visceral feeling of safety.

Porges’s theory provides an explanation: The autonomic nervous system regulates three fundamental physiological states. The level of safety determines which one of these is activated at any particular time. Whenever we feel threatened, we instinctively turn to the first level, social engagement. We call out for help, support, and comfort from the people around us. But if no one comes to our aid, or we’re in immediate danger, the organism reverts to a more primitive way to survive: fight or flight. We fight off our attacker, or we run to a safe place. However, if this fails—we can’t get away, we’re held down or trapped—the organism tries to preserve itself by shutting down and expending as little energy as possible. We are then in a state of freeze or collapse.

Any threat to our safety or social connections triggers changes in the areas innervated by the VVC. When something distressing happens, we automatically signal our upset in our facial expressions and tone of voice, changes meant to beckon others to come to our assistance.11 However, if no one responds to our call for help, the threat increases, and the older limbic brain jumps in. The sympathetic nervous system takes over, mobilizing muscles, heart, and lungs for fight or flight.12 Our voice becomes faster and more strident and our heart starts pumping faster. If a dog is in the

room, she will stir and growl, because she can smell the activation of our sweat glands. Finally, if there’s no way out, and there’s nothing we can do to stave off the inevitable, we will activate the ultimate emergency system: the dorsal vagal complex (DVC). This system reaches down below the diaphragm to the stomach, kidneys, and intestines and drastically reduces metabolism throughout the body. Heart rate plunges (we feel our heart “drop”), we can’t breathe, and our gut stops working or empties (literally “scaring the shit out of” us). This is the point at which we disengage, collapse, and freeze.

trauma is expressed not only as fight or flight but also as shutting down and failing to engage in the present. A different level of brain activity is involved for each response: the mammalian fight-or-flight system, which is protective and keeps us from shutting down, and the reptilian brain, which produces the collapse response. You can see the difference between these two systems at any big pet store. Kittens, puppies, mice and gerbils constantly play around, and when they’re tired they huddle together, skin to skin, in a pile. In contrast, the snakes and lizards lie motionless in the corners of their cages, unresponsive to the environment.

The Feeling of What Happens is, for me, his most important book, and reading it was a revelation.

[P]rimordial feelings provide a direct experience of one’s own living body, wordless, unadorned, and connected to nothing but sheer existence. These primordial feelings reflect the current state of the body along varied dimensions, . . . along the scale that ranges from pleasure to pain, and they originate at the level of the brain stem rather than the cerebral cortex. All feelings of emotion are complex musical variations on primordial feelings.8

What is taking place around us also affects our physical sensations. Seeing someone we recognize, hearing particular sounds—a piece of music, a siren—or sensing a shift in temperature all change our focus of attention and, without our being aware of it, prime our subsequent thoughts and actions.

The team’s brain scans showed that recalling an emotional event from the past causes us to actually reexperience the visceral sensations felt during the original event. Each type of emotion produced a characteristic pattern, distinct from the others. For example, a particular part of the brain stem was “active in sadness and anger, but not in happiness or fear.”10 All of these brain regions are below the limbic system, to which emotions are traditionally assigned, yet we acknowledge their involvement every time we use one of the common expressions that link strong emotions with the body: “You make me sick”; “It made my skin crawl”; “I was all choked up”; “My heart sank”; “He makes me bristle.”

Agency starts with what scientists call interoception, our awareness of our subtle sensory, body-based feelings: the greater that awareness, the greater our potential to control our lives. Knowing what we feel is the first step to knowing why we feel that way.

After I saw the wonderful movie March of the Penguins, I found myself thinking about some of my patients. The penguins are stoic and endearing, and it’s tragic to learn how, from time immemorial, they have trudged seventy miles inland from the sea, endured indescribable hardships to reach their breeding grounds, lost numerous viable eggs to exposure, and then, almost starving, dragged themselves back to the ocean. If penguins had our frontal lobes, they would have used their little flippers to build igloos, devised a better division of labor, and reorganized their food supplies. Many of my patients have survived trauma through tremendous courage and persistence, only to get into the same kinds of trouble over and over again. Trauma has shut down their inner compass and robbed them of the imagination they need to create something better.

However, traumatized people chronically feel unsafe inside their bodies: The past is alive in the form of gnawing interior discomfort. Their bodies are constantly bombarded by visceral warning signs, and, in an attempt to control these processes, they often become expert at ignoring their gut feelings and in numbing awareness of what is played out inside. They learn to hide from their selves.

The more people try to push away and ignore internal warning signs, the more likely they are to take over and leave them bewildered, confused, and ashamed. People who cannot comfortably notice what is going on inside become vulnerable to respond to any sensory shift either by shutting down or by going into a panic—they develop a fear of fear itself.

The price for ignoring or distorting the body’s messages is being unable to detect what is truly dangerous or harmful for you and, just as bad, what is safe or nourishing. Self-regulation depends on having a friendly relationship with your body. Without it you have to rely on external regulation—from medication, drugs like alcohol, constant reassurance, or compulsive compliance with the wishes of others.

Many of my patients respond to stress not by noticing and naming it but by developing migraine headaches or asthma attacks.15 Sandy, a middle-aged visiting nurse, told me she’d felt terrified and lonely as a child, unseen by her alcoholic parents. She dealt with this by becoming deferential to everybody she depended on (including me, her therapist). Whenever her husband made an insensitive remark, she would come down with an asthma attack. By the time she noticed that she couldn’t breathe, it was too late for an inhaler

to be effective, and she had to be taken to the...

There was no activation of any part of the brain involved in social engagement. In response to being looked at they simply went into survival mode.
