Somatic Therapy: Healing Trauma Through the Body

Bessel van der Kolk's landmark book, The Body Keeps the Score, introduced millions of readers to a concept that trauma therapists had understood for decades: trauma is not just a psychological wound — it is a physiological one. The body remembers what the mind cannot process, and it expresses that memory through chronic tension, pain, dysregulated breathing, and a nervous system perpetually braced for threat.

Somatic therapy — from the Greek soma, meaning body — is a family of therapeutic approaches that work directly with these physical manifestations of trauma, rather than relying solely on verbal narrative and cognitive reprocessing.

Why Talk Therapy Alone Is Sometimes Not Enough

Traditional psychotherapy operates primarily through the neocortex — the brain's rational, language-processing centre. Trauma, however, is primarily stored in subcortical structures: the amygdala, hippocampus, and brainstem — regions that do not respond to language or logic in the same way.

This is why trauma survivors can understand intellectually that they are safe, yet their body continues to respond as though the threat is present. The rational mind and the survival brain are operating on different systems, and talking alone cannot always bridge the gap.

Somatic approaches work bottom-up rather than top-down — engaging the body and nervous system directly, then allowing insight and narrative to emerge from that foundation rather than the reverse.

The Polyvagal Framework

Understanding somatic therapy requires a basic grasp of Polyvagal Theory, developed by neuroscientist Stephen Porges. The theory describes three hierarchical states of the autonomic nervous system:

Ventral vagal (safe and social): The state of calm, connection, and engagement. This is where healing happens.

Sympathetic activation (fight or flight): The emergency response. Appropriate for genuine threats; problematic when chronically activated.

Dorsal vagal (freeze or collapse): The last-resort survival response. Often the state in which severe or chronic trauma is experienced.

Trauma dysregulates the nervous system's ability to move fluidly between these states. Somatic therapy aims to restore this flexibility — helping the nervous system find its way back to ventral vagal safety.

Core Somatic Approaches

Somatic Experiencing (SE)

Developed by Peter Levine, SE is based on the observation that animals in the wild rarely develop PTSD, despite frequent life-threatening encounters. SE works by gently tracking bodily sensations, helping clients complete interrupted survival responses, and gradually discharging stored traumatic energy in small, titrated doses.

Sensorimotor Psychotherapy

Developed by Pat Ogden, Sensorimotor Psychotherapy integrates somatic awareness with attachment theory and cognitive approaches. It pays particular attention to posture, gesture, and movement as expressions of psychological states.

EMDR

Eye Movement Desensitisation and Reprocessing (EMDR) incorporates bilateral physical stimulation — eye movements, taps, or tones — to facilitate the reprocessing of traumatic memories. The bilateral stimulation appears to activate the brain's natural information-processing system, allowing traumatic memories to be integrated rather than remaining frozen and fragmented.

What to Expect in Somatic Therapy

A somatic therapy session looks quite different from traditional talk therapy. Your therapist will invite you to slow down and notice physical sensations — the weight of your body in the chair, the quality of your breath, areas of tension or ease. The pace is deliberately slow. Somatic therapists work within what is called the window of tolerance — keeping activation at a level that is challenging but not overwhelming.

Evidence and Effectiveness

Multiple randomised controlled trials have demonstrated the effectiveness of SE and EMDR for PTSD, with effect sizes comparable to or exceeding those of established cognitive approaches. A 2017 meta-analysis found that body-oriented therapies produced significant reductions in PTSD symptoms, depression, and anxiety.

Beginning the Journey

If you are considering somatic therapy, seek a therapist specifically trained in a recognised somatic modality — SE, Sensorimotor Psychotherapy, or EMDR. The therapeutic relationship is particularly important in this work; safety and trust are not just desirable but neurologically necessary for healing to occur.

The body has been carrying your story. Somatic therapy offers it a way to finally set it down.
