How Trauma Gets Stored in the Body (And How to Release It)
You’ve probably heard the phrase “trauma stored in the body.” It shows up in book titles, therapist bios, wellness articles. But what does it actually mean? Is it a metaphor — a poetic way of describing emotional pain — or is something literally happening in your physical body when you experience trauma?
The answer is the latter. And understanding it changes everything about how healing becomes possible.
What Trauma Actually Is
Trauma is not the event itself. It’s what happens inside you in response to the event.
When something happens that overwhelms your capacity to cope — whether it’s a single acute event like an accident or assault, or a chronic experience like childhood neglect or a toxic relationship — your nervous system responds in a specific way. It activates a survival response. Stress hormones flood the body. The heart rate spikes. Muscles brace. The senses sharpen. Every system in the body mobilizes for survival.
This is not a psychological flaw. It’s a biological feature. The fight-flight-freeze-fawn response is one of the most sophisticated survival mechanisms in the animal kingdom, and it’s saved human lives for as long as humans have existed.
The problem arises when the response doesn’t complete.
When the Response Gets Stuck
In an ideal scenario, after a threat passes, the body would complete the survival cycle — discharging the mobilized energy through movement, breath, or the physical actions of fighting or fleeing — and then return to baseline. You’d feel the fear, your body would respond, the threat would resolve, and your nervous system would settle back into rest and regulation, perhaps with the help of a trusted loved one.
But this completion is often interrupted. In human life, we frequently can’t complete survival responses. We get through a crisis by holding ourselves together, keeping ourselves safe as best we can and the biological energy that was mobilized never gets discharged.
When this happens, the survival response doesn’t end — it just gets interrupted and stored. The mobilized energy stays in the nervous system, held in the body’s tissues, posture, muscle patterns, and autonomic states. The threat has passed, but physiologically, the body hasn’t gotten the message.
This is what it means for trauma to be stored in the body.
The Research Behind This
The somatic understanding of trauma is not fringe science. It’s grounded in decades of neuroscience and clinical research.
Pat Ogden, founder of Sensorimotor Psychotherapy, contributed a structured clinical framework for working with the body in trauma treatment. Where earlier somatic approaches focused primarily on autonomic discharge, Ogden's model maps the relationship between movement, posture, and psychological experience in precise detail — showing how habitual physical patterns like collapsed posture or braced shoulders are not just symptoms of trauma, but active organizers of identity and belief. Her work gave clinicians a concrete, body-first language for the therapeutic process.
Dr. Peter Levine, who developed Somatic Experiencing, spent years observing that animals in the wild rarely develop lasting trauma despite facing life-threatening situations regularly. He noticed that after a threatening encounter, animals naturally discharge survival energy through vigorous shaking, trembling, and spontaneous movement. The energy that was mobilized gets released through the body, and the animal returns to normal functioning.
Dr. Bessel van der Kolk, whose research on trauma has been foundational in the field, documented extensively how trauma changes the brain and body — showing that traumatic memories are encoded differently from ordinary memories, with a strong physiological component that includes changes in the body’s stress response systems, immune function, and the capacity for self-regulation.
Janina Fisher, a psychologist and former student of Bessel van der Kolk, expanded on this work by integrating parts-based approaches with somatic understanding. Her model recognizes that trauma fragments the self into distinct parts — each carrying its own physiological imprint — and that healing requires working with both the body and these internal systems simultaneously. Her work has been particularly influential in treating complex and developmental trauma.
Dr. Stephen Porges’ polyvagal theory (which has received some scientific criticism in recent years regarding the specific anatomical claims, but whose clinical utility remains widely recognized) describes how the autonomic nervous system has multiple states — from engaged and connected, to fight-or-flight, to freeze and shutdown — and how trauma can cause people to get stuck in the more defensive states.
The consensus across this body of work is clear: trauma is not primarily a cognitive or narrative phenomenon. It is a physiological one, with a corresponding physiological signature in the body.
What Stored Trauma Looks Like in the Body
Stored trauma doesn’t look the same for everyone. But here are some of the most common ways it shows up:
Chronic tension patterns. Many people who have experienced trauma carry persistent muscle tension in specific areas — the jaw, the shoulders, the neck, the chest, the abdomen. This tension is often below the threshold of conscious awareness. It’s just “how their body feels.” But it represents the body’s ongoing bracing against a threat that has technically passed.
Breathing dysregulation. Shallow, high-chest breathing is a hallmark of a nervous system stuck in sympathetic activation. Many trauma survivors breathe in a way that perpetually signals low-level threat to the brain.
Hypervigilance. The body stays on alert — scanning the environment for danger, startling easily, having trouble settling into rest or sleep. This is the nervous system doing its job, except the job never ends.
Freeze and shutdown. For some people, stored trauma shows up not as hyperactivation but as the opposite: numbness, disconnection, emotional flatness, a sense of not being fully present in the body or in life. This corresponds to the freeze response — the most ancient survival mechanism, associated with the dorsal vagal nervous system — in which the body essentially plays dead.
Somatic symptoms. Chronic pain, digestive issues, fatigue, headaches, and other physical symptoms without clear medical explanation are sometimes related to trauma held in the body. This is not to say all physical symptoms are psychological — they are not. But the mind-body connection in trauma is real, and for some people, unprocessed trauma finds expression in the body’s physical symptoms.
Emotional reactivity. When the nervous system is chronically dysregulated, emotional responses can be disproportionate to present-day triggers. Something small happens, and the reaction is enormous — not because of the small thing, but because it landed on a system that was already primed for danger.
How Trauma Gets Released: The Role of Somatic Therapy
If trauma is held in the body, healing it requires working at the level of the body. This is the foundation of somatic therapy approaches.
The goal of somatic trauma work is not to re-experience the trauma in full — this approach, sometimes called flooding, can actually reinforce rather than resolve the trauma response. Instead, somatic trauma therapy works at the edges: with the body sensations associated with difficult experiences, approached carefully, slowly, and with constant attention to keeping the person within a manageable range of activation.
Key elements of how somatic therapy helps release stored trauma:
Titration. Working with small amounts of difficult material at a time. Rather than telling the full story, a somatic therapist might focus attention on a single physical sensation associated with the memory — the tightness in the throat, the sensation in the stomach — and track what happens to it with sustained, gentle attention.
Pendulation. Moving attention back and forth between areas of activation and areas of relative ease or neutrality. This teaches the nervous system that it can move between states — that it doesn’t have to stay stuck in one — which is itself healing.
Completing interrupted responses. When the body is guided to complete the movement or action it was mobilizing for during the original threat — the pushing away, the fleeing, the protective gesture — the incomplete survival response gets to finish. The energy that was stuck gets discharged. The nervous system updates: the threat has ended.
Discharging activation. This might look like trembling, shaking, spontaneous movement, deep sighing, yawning, or waves of sensation. These are signs of the nervous system doing what it’s supposed to do — completing and releasing stored activation.
Building resources. A crucial part of somatic trauma work is also helping the nervous system build new experiences of safety and regulation — not just releasing what’s stuck, but laying down new neural pathways associated with calm, groundedness, and connection.
Healing Is Not Linear
One thing worth saying clearly: somatic trauma healing is not a straight line. There will be sessions that feel like significant breakthroughs and sessions that feel flat. There will be periods of increased sensitivity as material that has been held for years begins to move. There will be moments of unexpected grief, or anger, or relief.
This is not a sign that something is going wrong. It’s a sign that something is finally moving.
The body has an innate capacity for healing. Somatic therapy’s fundamental premise is that this capacity is already within you — it just needs the right conditions to emerge. Those conditions are safety, pacing, and the presence of a skilled therapist who knows how to accompany a nervous system on its journey home.
Healing is possible — even from here.
