The Body Keeps the Score — What That Actually Means

The phrase "the body keeps the score" has become so widely used in discussions of trauma that it risks becoming a slogan divorced from its actual meaning. The specific claim is precise and important: traumatic experience is encoded in the body's physiological systems, in ways that persist, influence behavior, and generate suffering that cannot be fully resolved by addressing the narrative layer alone.

Bessel van der Kolk, psychiatrist and founder of the Trauma Research Foundation, spent decades building the research basis for this claim. The evidence he and others assembled draws on neuroscience, immunology, endocrinology, and clinical observation. What it shows is that trauma is not primarily a story about the past. It is a set of physiological states that the body continues to generate in the present.

What "Storage" in the Body Actually Means

The body does not store trauma in the way a filing cabinet stores documents. It stores it as physiological patterns: the calibration of the autonomic nervous system's threat-detection, the tension patterns held in muscles, the respiratory baseline, the reactivity of the HPA axis, and the body-level associations that constitute what Antonio Damasio, professor of neuroscience at the University of Southern California, calls somatic markers.

Damasio's somatic marker hypothesis, developed through decades of research on decision-making and body-brain interaction, describes how the body's physiological states become associated with past experiences and are automatically triggered when situations resembling those experiences arise. A somatic marker is a body state, a tightening in the chest, a change in breathing, a gut response, that fires before conscious reasoning has engaged and shapes what happens next in both perception and behavior.

In traumatic experience, somatic markers become associated with survival-level threat. They do not simply record that something was difficult. They encode the full physiological mobilization that the original experience required. When cues in the present environment resemble the original context, those markers re-activate. The body responds to the present situation as if it were the past situation, because from the body's perspective, the pattern match is sufficient to trigger the stored response.

The Two Memory Systems

Understanding why talking about trauma has limits requires understanding the distinction between explicit and implicit memory.

Explicit memory is consciously accessible: the narrative account of what happened, when, with whom, and in what sequence. It is processed through the hippocampus and encoded in forms that can be retrieved and reported in language. This is the memory system that therapy conversations primarily engage.

Implicit memory encompasses what the body and nervous system learned from experience without necessarily generating a verbal narrative. It includes procedural memory (how to do things), emotional memory (what situations feel like, what to expect from them), and the physiological responses that have been conditioned by past experience. Implicit memory does not generate a story. It generates a body state.

Research by van der Kolk and others using brain imaging showed something significant: when trauma survivors recalled traumatic memories, activation decreased in Broca's area, the brain region most associated with expressive speech and the translation of experience into language. At the same time, activation increased in subcortical and limbic regions associated with emotional memory, threat response, and body-based experience. The person having the traumatic memory was not primarily in language. They were in the body's record of what happened.

This dissociation between the verbal and somatic records of experience explains a pattern that clinicians and trauma survivors both recognize: a person can describe what happened to them clearly, know the narrative by heart, and still have a body that responds to related cues with the full physiological activation of the original experience. The narrative has been processed at the verbal level. The body's record has not been updated.

The Autonomic Nervous System as Record-Keeper

Peter Levine, developer of Somatic Experiencing and founder of the Foundation for Human Enrichment, has emphasized a specific dimension of somatic trauma storage: the incomplete defensive response.

When an animal or person faces a survival threat, the nervous system mobilizes a defensive response: fight, flight, or freeze. In many traumatic situations, particularly those involving overwhelming threat where fight or flight are impossible, the defensive response is mobilized but cannot complete. The energy that was organized for survival action remains in the system without the resolution that would have come from completing the response.

Levine's work, and the clinical method of Somatic Experiencing that came from it, is built on the observation that this incomplete activation remains physiologically present. It is held in the body's tension patterns, in the collapsed or braced posture, in the breathing that stops short of full exhalation. When somatic work facilitates the completion of these interrupted responses, the body-level activation that has been held in incomplete form can begin to resolve.

This is a different model than the cognitive one, and it has different treatment implications. The target of the work is not the meaning of what happened. It is the physiological process that was interrupted.

Pat Ogden and Sensorimotor Patterns

Pat Ogden, founder of Sensorimotor Psychotherapy, has documented how trauma is held in the body's movement and postural patterns. She describes trauma as producing characteristic action tendencies, habitual ways of holding and moving the body that reflect the defensive or submissive postures that were adaptive in the original traumatic context.

A person who learned to make themselves small in a context of threat may maintain a collapsed posture decades later, not because they are choosing it, but because the body's pattern library was built in that context. A person who habitually braces may be carrying the defensive tension of situations in which bracing was protective. These patterns run continuously and consume resources without the person's conscious awareness.

Ogden's approach works directly with these patterns: helping the person become aware of them, interrupt them, and practice the physical patterns associated with different internal states. The body's posture and movement carry physiological implications, and changing the movement patterns changes the states they are associated with.

Why Verbal Therapy Alone Is Often Insufficient

This is not an argument against verbal therapy. Verbal therapy can be profoundly useful for building narrative coherence, reducing shame, developing a framework for understanding experience, and creating the relational safety within which healing happens. What it is less well-suited to is directly changing the body's stored physiological patterns.

Van der Kolk's research and clinical work consistently points toward the necessity of body-level intervention for the somatic dimension of trauma. In his studies and clinical observations, approaches that engaged the body directly, including yoga, theater work, somatic therapies, and rhythmic group activities, produced measurable changes in trauma populations that verbal therapies alone had not achieved.

The explanation is structural: verbal therapy primarily operates through the cortical, language-based systems. The body's trauma record is held in subcortical and autonomic systems that do not primarily process language. Changing those systems requires working in their own medium, through body-level experience rather than through narrative.

What Actually Changes the Body-Level Record

The approaches with the strongest evidence base for somatic trauma resolution have several features in common. They engage the body's own physiological processes. They work with the nervous system's activation in a titrated way, staying within the window of tolerance rather than flooding. They facilitate completion of what was interrupted.

Somatic Experiencing, EMDR, sensorimotor psychotherapy, and yoga-based trauma interventions all show evidence of physiological change beyond what narrative approaches alone produce. The change is not simply behavioral. It is measurable in physiological markers: HPA axis reactivity, heart rate variability, inflammatory markers, and the body's baseline threat calibration.

The Life That Is Already Yours works with the layer of experience that verbal understanding alone does not fully reach. Anxiety Rewired addresses the physiological dimension of what remains after the story has been told.

What Helps

Approach the body's record with curiosity: The physiological patterns that hold traumatic experience are not malfunctions. They are the body's solutions to what was, at the time, a genuine survival problem. Approaching them with curiosity rather than frustration tends to produce better outcomes in body-based work.

Work within the window of tolerance: Approaches that push into traumatic activation without the resources to process it can increase dysregulation rather than reduce it. Effective somatic work is titrated: it approaches the activation in doses small enough to allow processing.

Use narrative and somatic work together: The verbal understanding of what happened and why the body responds as it does provides a framework that makes somatic work more navigable. The somatic work updates the body-level record that the narrative cannot reach alone.

Build body-level safety before processing content: The body's capacity to process traumatic activation requires a baseline of physiological safety. Developing that baseline, through breath, movement, grounding, and relational co-regulation, is often a necessary precursor to deeper work.

Understand that resolution is physiological, not only cognitive: A person can arrive at full cognitive understanding of their trauma history without the body-level record having shifted. The sense that healing is complete, at the body's level, feels different from intellectual understanding. That distinction matters for knowing when the work is done.
