Your Body Keeps the Score, But Can It Be Rewritten?

Tom had not been to Vietnam in thirty years.

He had built a career. Raised children. Moved to a quiet suburban street where the biggest disruption was a neighbor mowing the lawn on Saturday mornings. By every visible measure, the war was over. It had been over for decades.

But Tom's body did not know that.

Every time a car backfired on his street, he hit the ground. Not metaphorically. Not a flinch. His legs gave out, his hands covered his head, and he was on the pavement before he had time to form a single conscious thought. His heart rate would spike past 160. His breathing would go shallow and ragged. His pupils would dilate. And for several seconds, sometimes longer, he was not on a suburban street at all. He was in a rice paddy in 1969, waiting for the next round of incoming fire.

Tom was one of the patients described in Dr. Bessel van der Kolk's clinical research at the Trauma Center in Brookline, Massachusetts. Van der Kolk had been studying trauma responses since the 1970s, and cases like Tom's were not unusual in his practice. What was unusual was van der Kolk's conclusion about why traditional treatment was failing these patients.

The problem was not that Tom had bad memories. It was that Tom's body had never left the war.

His conscious mind knew perfectly well that he was safe. He could describe the war, analyze his reactions, articulate what was happening and why. He had spent years in talk therapy doing exactly that. And none of it stopped the reaction. Because the reaction did not originate in his conscious mind. It originated in his body, in autonomic circuits that operated faster than thought, below the reach of any purely cognitive intervention.

Van der Kolk published these observations and a career's worth of research in The Body Keeps the Score in 2014. The book became a cultural phenomenon, spending years on bestseller lists. But the core finding, the one that changed how we think about human suffering, is deceptively simple: trauma is stored in the body, not just the brain. And approaches that only address the mind leave the body's record untouched.

Two Directions of Intervention

To understand why Tom could talk about Vietnam for years without his body's response changing, you need to understand the difference between two fundamentally different approaches to the nervous system.

Top-down approaches work from cognition toward the body. Talk therapy, cognitive behavioral therapy (CBT), affirmations, journaling, insight-oriented work. These interventions start with conscious thought and attempt to influence the nervous system through understanding, reframing, and cognitive restructuring. The premise is that if you change how you think about an experience, you change how your body responds to it.

Bottom-up approaches work from the body toward cognition. Somatic experiencing, breathwork, movement practices, vagal toning exercises, interoceptive training. These interventions start with the body's physiological state and attempt to change the nervous system directly, which then shifts thought and emotional patterns as a downstream consequence.

Both have value. Neither is wrong. But the research increasingly shows that for patterns encoded in the autonomic nervous system, particularly those rooted in early life or repeated traumatic exposure, top-down approaches alone are insufficient.

The reason is structural. When a threat response is encoded, it gets stored in subcortical circuits: the amygdala, the brainstem, the autonomic nervous system. These circuits operate faster than the prefrontal cortex and do not require conscious processing to activate (LeDoux, 1996). This is by design. If you had to consciously evaluate every potential threat before responding, you would not survive long. The system is built for speed, not accuracy.

The consequence is that talking about the pattern, understanding the pattern, and even wanting desperately to change the pattern does not directly access the circuits where the pattern lives. Tom understood his trauma. His understanding had zero effect on the circuits that threw him to the ground when a car backfired. The signal traveled from his ears to his amygdala to his body in milliseconds, bypassing the prefrontal cortex entirely.

Polyvagal Theory: The Map of Your Nervous System

In 1994, Stephen Porges introduced a framework that gave clinicians and researchers a new way to understand the nervous system's role in human behavior. He called it polyvagal theory.

The traditional view of the autonomic nervous system was binary: sympathetic (fight or flight) and parasympathetic (rest and digest). Porges proposed a more nuanced model based on the vagus nerve, the longest cranial nerve in the body, which runs from the brainstem through the face, throat, heart, lungs, and gut.

Porges identified three distinct states, each governed by a different branch of the autonomic nervous system (Porges, 2011):

Ventral vagal (safe and social). This is your optimal state. Your nervous system reads the environment as safe. You can think clearly, connect with others, be creative, make decisions. Your breathing is slow and full. Your facial muscles are relaxed. You feel present.

Sympathetic (fight or flight). Your nervous system has detected a threat. Heart rate increases. Muscles tense. Breathing becomes shallow and rapid. You are mobilized for action, either to fight the threat or flee from it. Higher cognitive functions are deprioritized. You are reactive, not reflective.

Dorsal vagal (freeze or shutdown). When the threat is overwhelming and neither fight nor flight is possible, the nervous system drops into its oldest survival response: immobilization. Heart rate plummets. Energy drains. You feel numb, disconnected, foggy, or collapsed. This is the state people describe as "checking out" or "going blank."

What makes polyvagal theory so useful in practice is that it explains behavior not as a choice but as a state. When someone is in dorsal vagal shutdown, they are not lazy or unmotivated. Their nervous system has taken them offline. When someone is in sympathetic activation, they are not overreacting. Their body has detected a threat and is responding accordingly.

And here is the critical insight: you cannot think your way from one state to another. You cannot reason yourself from freeze into ventral vagal. The shift has to happen through the body, through the nervous system itself, through the same bottom-up pathways that got you into the state in the first place.

What Gets Stored and Where

Van der Kolk's research identified something that most people find initially surprising: the body stores threat responses independently of conscious memory.

In clinical settings, patients would present with chronic pain, tension, digestive issues, or movement restrictions that had no identifiable medical cause. Further investigation often revealed that the physical symptoms corresponded to specific traumatic experiences. A patient who had been physically restrained as a child might hold chronic tension in the wrists and forearms. A patient who had been silenced might hold tension in the jaw and throat. The body had encoded the threat in the tissue itself (van der Kolk, 2014).

This finding is supported by research on interoception, the brain's ability to sense and interpret internal body signals. Craig (2009) demonstrated that interoceptive awareness is processed through the insular cortex and is closely linked to emotional experience. In other words, the body is not merely a vessel for the brain. It is an active participant in emotional processing. What you feel physically and what you feel emotionally are processed through overlapping neural systems.

For people running unconscious patterns, this means something important: the pattern does not just live in your thoughts or beliefs. It lives in the tension in your shoulders. The knot in your stomach. The tightness in your chest. The chronic clenching of your jaw. These are not random physical complaints. They are the body's record of experiences the conscious mind may have forgotten or never fully processed.

The Practice: The Body Scan Check-In

If the pattern lives in the body, then the body is where awareness needs to begin.

Here is a practice you can try right now. I call it the Body Scan Check-In.

Stop what you are doing. Sit still for sixty seconds. And scan from the top of your head to the tips of your toes.

Move slowly. Start at your scalp. Is there tension there? Move to your forehead, your eyes, your jaw. Is your jaw clenched right now? Most people discover that it is, and they had no idea.

Move down to your throat. Your shoulders. Are they raised? Tight? Heavy? Move to your chest. Is there pressure there? Constriction? Openness?

Continue through your stomach, your lower back, your hips, your legs, your feet. Take your time.

Now answer two questions:

Where is there tension?

What emotion lives there?

Write down what you find. Just a sentence or two. "Tension in my jaw. Feels like frustration." "Pressure in my chest. Feels like anxiety I cannot name." "My shoulders are concrete. It feels like responsibility."

That is your data. The tension you just noticed has probably been there for hours, days, maybe years. You simply were not paying attention to it. Your conscious mind was busy with tasks and thoughts while your body was quietly carrying the weight of patterns you have never examined.

This is not a relaxation exercise. It is an investigation. You are gathering evidence about where your patterns physically reside. And as research on interoceptive awareness demonstrates, the simple act of turning attention toward internal body states begins to shift the relationship between the person and the pattern (Mehling et al., 2012). You are not fixing anything. You are creating the conditions for the nervous system to begin its own reorganization.

Rewriting the Record

So can the body's score be rewritten? The research says yes, but not through the methods most people try first.

Neuroplasticity, the brain's ability to form new neural connections throughout life, is well established (Doidge, 2007). The same mechanism that encoded the original pattern can encode a new one. Long-term potentiation works in both directions: pathways that are repeatedly activated get stronger, and pathways that are not activated gradually weaken through a process called synaptic pruning.

The practical implication is that changing a body-based pattern requires body-based intervention. Repeated experiences of safety in the body. Somatic practices that give the nervous system evidence, not arguments, that the threat is over. Breathwork that directly activates the ventral vagal system. Movement that releases the stored tension. Interoceptive training that rebuilds the connection between conscious awareness and physical sensation.

Tom, the veteran from van der Kolk's practice, eventually found relief through somatic approaches after years of talk therapy had produced understanding but not change. His body needed a different kind of evidence than words could provide. It needed to learn, through repeated physical experience, that the war was actually over.

The pattern in your body may not come from a war zone. But it comes from somewhere. And wherever it was encoded, that is where it needs to be addressed.

Your patterns live in your body, not your thoughts.
