You might have heard the phrase “the body keeps the score.” It’s not just a book title — it reflects one of the most important shifts in how we understand trauma. For decades, trauma was treated as something purely psychological: a memory, a thought pattern, a story in the mind. But a growing body of research — and the lived experience of thousands of trauma survivors in Canada and around the world — tells us something different.
Trauma lives in the body. It shapes how we breathe, how tense our shoulders are, how our gut responds to stress, even how our heart rate behaves in ordinary moments. Understanding this is not just scientifically interesting — it’s practically essential for healing.
This article explores how childhood trauma is stored physically, what that looks like in everyday life, and what types of therapy in Ontario can help the body, not just the mind, begin to heal.
Why the Body Stores Trauma
When a child experiences something threatening — abuse, neglect, violence, chronic instability — the nervous system responds with a survival response. The amygdala (the brain’s alarm system) fires, flooding the body with stress hormones like cortisol and adrenaline. Heart rate spikes, muscles tense, and the body prepares to fight, flee, or freeze.
In adults who experience a one-time trauma and have a stable life before and after, this response resolves. The nervous system calms down, the memory gets processed, and the body returns to baseline. But for children — especially those who experienced repeated, prolonged, or relational trauma — the nervous system never fully resets. The threat response becomes the default.
Dr. Bessel van der Kolk, whose research spans decades, describes this as the body being “stuck” in survival mode: chronically scanning for danger, never fully relaxing, interpreting neutral signals as threats. This is not a character flaw or weakness. It is a physiological adaptation to an unsafe environment.
How Trauma Shows Up in the Body
The physical signatures of stored trauma are varied — and often misunderstood or misdiagnosed. Common body-based manifestations include:
Chronic Tension and Pain
Many trauma survivors carry tension in specific areas of the body — the jaw, neck, shoulders, hips, and chest. This isn’t just “stress.” The muscles have been braced for protection, sometimes for years, and haven’t learned it’s safe to release. Chronic pain, headaches, and temporomandibular joint (TMJ) issues are frequently reported by people with trauma histories.
Gastrointestinal Symptoms
The gut is sometimes called the “second brain” because of its dense network of nerves. Trauma disrupts the gut-brain connection, contributing to irritable bowel syndrome (IBS), nausea, stomach pain, and digestive irregularities that have no clear medical cause. In Mississauga clinics and across Ontario, many people with these symptoms are eventually connected to trauma histories.
Hyperarousal and Hypervigilance
Living in a state of constant alertness — startling easily, struggling to sleep, feeling “on edge” — is a body-based symptom of unresolved trauma. The nervous system has learned that relaxation is dangerous, so it stays elevated long past the time the threat has gone.
Numbness and Dissociation
On the other end of the spectrum, some trauma survivors experience the opposite: a sense of being disconnected from their body, feeling numb, or not quite “in” their physical self. This is also a nervous system adaptation — the freeze or fawn response — and it shows up as emotional flatness, difficulty feeling pleasure, or a sense of going through the motions of life.
Illness and Immune Dysregulation
The ACEs (Adverse Childhood Experiences) research — one of the largest public health studies ever conducted — found a clear dose-response relationship between childhood trauma and adult physical health outcomes: higher ACE scores correlate with increased rates of heart disease, autoimmune conditions, cancer, and premature death. Chronic stress hormones suppress immune function and cause systemic inflammation over time.
Why Talking About It Isn’t Always Enough
One of the reasons traditional talk therapy alone sometimes falls short for trauma is precisely because trauma is not just a cognitive event. You can narrate what happened, understand why it affected you, and still have a body that trembles at a raised voice or a gut that knots when someone looks at you with displeasure.
The language centres of the brain (Broca’s area) are often less active during trauma recall — which is why many trauma survivors struggle to put their experience into words. “Talk therapy” approaches this through the mind-body divide; body-based approaches close that gap.
This doesn’t mean talk therapy has no role — it absolutely does. But for many people with childhood trauma histories, lasting healing requires working through the body, not just around it.
Body-Based Therapies That Help
At True Therapy in Mississauga, Sonia works with a trauma-informed framework that recognises the body’s role in healing. Evidence-based approaches that address trauma somatically include:
Somatic Experiencing (SE)
Developed by Peter Levine, SE works by gently tracking body sensations and titrating exposure to trauma — allowing the nervous system to complete the thwarted survival responses it was unable to finish. This can look like slight trembling, temperature changes, or deep spontaneous breaths as tension releases.
EMDR Therapy
Eye Movement Desensitization and Reprocessing (EMDR) involves bilateral stimulation (eye movements, tapping, or sounds) while processing trauma memories. It works on the body and the brain simultaneously, helping traumatic memories become integrated rather than frozen and reactive.
Trauma-Informed CBT
Cognitive behavioural therapy adapted for trauma includes psychoeducation about the body’s stress responses, grounding techniques, and gradual exposure work — all of which help the nervous system learn that certain stimuli are no longer threatening.
Mindfulness-Based Approaches
Mindfulness practices teach the body to tolerate present-moment experience without reacting from the past. With guidance and a safe therapeutic relationship, people with trauma histories can learn to be present in their bodies — perhaps for the first time.
Frequently Asked Questions
Can you feel trauma being released from the body?
Yes — many people describe physical sensations when trauma releases: spontaneous trembling, warmth spreading through the body, deep sighing, tears without obvious sadness, or a feeling of lightness. These are signs the nervous system is completing what it started.
Where is trauma stored in the body?
Trauma doesn’t live in one specific location. Research suggests the nervous system, muscles, and fascia all hold the imprint of traumatic experience. Common areas of held tension include the hips, jaw, chest, shoulders, and belly.
Can physical symptoms from trauma be reversed?
Yes — with appropriate trauma therapy, many physical symptoms associated with stored trauma can reduce significantly. The nervous system retains plasticity throughout life, meaning healing is possible at any age.
How do I know if my physical symptoms are trauma-related?
If you’ve had physical symptoms (chronic pain, gut issues, sleep disturbance, unexplained fatigue) that haven’t resolved with medical treatment and you have a history of childhood adversity or trauma, it’s worth exploring with a trauma-informed therapist.
Healing Is Possible at Any Age
If you grew up in Ontario or anywhere in Canada with an unsafe, unstable, or painful childhood, the effects may still be living in your body today — even if decades have passed. This is not a life sentence. The nervous system is adaptable, and with the right support, real healing is possible.
At True Therapy in Mississauga, Sonia offers a safe, trauma-informed space to begin that process — gently, at your pace.
