Unresolved Trauma and the Body: How Trauma is Stored in Our Muscles, Fascia, and Nervous System

Trauma is not just something that happens in the mind; it lives in the body. Long after an overwhelming experience has passed, its effects can linger in posture, muscle tension, breathing patterns, and even how we digest food or respond to touch. When trauma remains unresolved, the body continues to operate as if the danger is still present, keeping us stuck in survival mode.

Understanding how trauma is stored in the body is a vital step toward healing. This article explores how the nervous system, muscles, and fascia absorb and retain traumatic stress and how that stored trauma can begin to be released.

The Nervous System: Survival on Loop

When we experience trauma, the body automatically engages a survival response: fight, flight, freeze, or fawn. These responses are driven by the autonomic nervous system and are meant to be temporary. But when trauma is unresolved, the nervous system can remain stuck in these states.

Some people live in hyperarousal, constantly on edge, anxious, and unable to relax. Others become hypo-aroused, feeling flat, numb, or disconnected from their bodies. These survival patterns become chronic and shape not only how we feel but how we move and inhabit our bodies.

Muscular Armouring: Tension as Protection

One of the clearest ways trauma manifests is through chronic muscular tension. This is what psychoanalyst Wilhelm Reich called muscular armour, the body's way of defending against overwhelming feelings or perceived threats. Reich observed that people often develop unconscious patterns of muscle tension to protect themselves emotionally, which eventually become fixed in their posture and movement.

Building on Reich’s work, Alexander Lowen identified how specific emotional conflicts can show up in distinct bodily patterns or character structures. For example:

• People who experienced early shame may hold their chest collapsed inward

• Those with suppressed rage may clench their jaws or fists without knowing why

• Trauma survivors might keep their shoulders permanently raised or hips rigid, unconsciously bracing against a threat that is no longer there.

These patterns are not just symbolic. They are physiological responses that shape how we experience the world and ourselves.

Fascia: The Connective Tissue That Carries Memory

Fascia is the web-like connective tissue that surrounds muscles and organs. It supports movement and transmits tension throughout the body. Emerging research suggests fascia also plays a role in emotional memory, which may explain why certain physical movements or stretches can trigger strong emotional responses.

Trauma can cause fascia to become dense, dehydrated, and constricted. This contributes to stiffness, restricted movement, and chronic pain. Therapies such as myofascial release, craniosacral therapy, and trauma-informed bodywork help soften these restrictions and support emotional release.

The Gut-Brain Connection: When Trauma Lives in the Belly

The gut contains its own nervous system, the enteric nervous system, which communicates with the brain through the vagus nerve. This is why we often feel emotions in the stomach, such as butterflies, nausea, tightness, or loss of appetite. Trauma disrupts this gut–brain communication. Survivors often experience symptoms like bloating, IBS, reflux, or chronic digestive issues, even when no physical cause is found. This is not just stress; it is the nervous system expressing unresolved threat.

Practices that stimulate the vagus nerve such as breathwork, cold exposure, chanting, or gentle yoga can help regulate this system and restore a sense of internal safety.

Why Talking Is Not Enough

Many trauma survivors find that even after years of talk therapy, their bodies still feel tense, reactive, or shut down. That is because trauma is not only stored in memory. It is held in muscle, fascia, breath, and nervous system patterns. Without engaging the body, these imprints can remain stuck.

This is where somatic approaches become essential. Whether through movement, breathwork, or hands-on therapy, reconnecting with the body is often the missing link in trauma recovery.

Starting to Reclaim the Body

Healing does not require reliving every detail of the trauma. It means creating new experiences of safety, presence, and embodiment. A few ways to begin:

Breath Awareness

Deep, slow breathing helps calm the nervous system and signals to the body that it is safe.

Posture Check-Ins

Notice how you are holding yourself throughout the day. Where do you tense up? What happens when you soften?

Gentle Movement

Trauma-informed yoga, walking, or stretching can help reconnect with bodily sensations and shift long-held tension.

Body-Based Therapy

Working with a trained somatic therapist or bodyworker can support the release of trauma stored in the tissues.

Conclusion: The Body as a Guide to Healing

Unresolved trauma changes how we live in our bodies. It affects our breath, our movement, our digestion, and our posture. But the body is not just a container for pain; it is also the path to healing. Reich and Lowen taught us that the body reflects our emotional history. Modern 
neuroscience confirms that trauma lives in the nervous system and tissues. And emerging somatic therapies offer grounded, practical ways to release it.

The body remembers, but it also knows how to let go.
