Somatic Therapy & Healing from Trauma: Understanding the Body’s Memory

An evidence-based exploration of how trauma lives in the body and how somatic approaches facilitate healing

Introduction

The famous words of psychiatrist Bessel van der Kolk, “The body keeps the score,” have become foundational to our understanding of trauma recovery. Recent research suggests that cellular memory is responsible for our physical and emotional responses to specific events and stimuli, regardless of whether we are in actual physical danger or completely safe (BodyBio, 2024). This emerging understanding of how trauma becomes embodied at the cellular level has profound implications for both trauma survivors and the healthcare providers who work with them.

Somatic therapy represents a paradigm shift from traditional talk therapy approaches by recognizing that trauma is not merely a psychological phenomenon but a whole-body experience that requires whole-body healing. Virtually every behavioral pattern exhibited during routine activities of daily living results from learned data that is stored, or encoded, as cellular memory (Academy for Traumatic Stress Studies, 2025). This article explores the neurobiological foundations of trauma, the role of cellular memory in trauma storage, and how somatic therapy approaches offer pathways to healing that honor the body’s innate wisdom.

The Neurobiological Landscape of Trauma

The Amygdala as Neural Router

Understanding trauma requires appreciating the brain’s alarm system, centered around the amygdala. LeDoux has proposed that in emotional processing, sensory information may access the amygdala via two different routes, called the low road and the high road (Journal of Neuropsychiatry, 2019).

The low road is a direct route to the amygdala from the thalamus, bypassing the cortex, that might promptly elicit fear defense responses without conscious recognition of the threat. By the high road, as soon as the sensory information projects to the thalamus, it is sent to the sensory cortex, insula, and PFC for a more complete analysis (conscious awareness of the conditioned stimulus), then this information is sent to the amygdala (Journal of Neuropsychiatry, 2019).

This dual-pathway system explains why trauma survivors often experience triggered responses before they can consciously process what’s happening. The amygdala essentially functions as a neural router, rapidly linking sensory data with emotional content and determining whether information should be processed through fast, survival-oriented circuits or slower, more deliberate conscious pathways.

Memory Encoding During Trauma

During traumatic events, bursts of adrenaline activate the amygdala, leading isolated sensory fragments to be vividly recalled. Specific sensory details such as visual images, smells, sounds, or felt experiences can be strongly imprinted and recalled (Dr. Arielle Schwartz, 2024).

This explains why trauma memories often lack coherent narrative structure. High arousal emotional and somatic experience disrupts the functioning of the hippocampus, which impairs our ability to recall all of the details or maintain a sense of sequential timing of events. We might have only fragments of sensory information (Dr. Arielle Schwartz, 2024).

The implications of this fragmented encoding are profound. Unlike typical memories that can be recalled and discussed coherently, traumatic memories exist as disconnected sensory fragments, body sensations, and emotional states that can be triggered without conscious awareness or understanding.

Cellular Memory: Where Trauma Lives in the Body

The Science of Embodied Trauma

Recent advances in neuroscience have revealed that trauma’s impact extends far beyond psychological symptoms. As it turns out, every one of our cells, not just neurons, has a kind of cellular memory that remembers and holds onto trauma from years prior, even from infancy when we have no conscious memory of what happened to us (BodyBio, 2024).

During the shock and stress of an event that is perceived as a physical or emotional threat, a special complex of hormonal messenger molecules are released by the limbic-hypothalamic-pituitary-adrenal system. These substances encode all the external and internal sensory impressions of the perceived threat as cellular memory (Academy for Traumatic Stress Studies, 2025).

This cellular encoding creates what researchers refer to as “traumatically encoded cellular memory patterns,” which can influence behavior, physical health, and emotional responses long after the original trauma occurred. When a person is not capable or willing or simply doesn’t have the time and resources to process their experience, it is stored in the cells in its raw form. If it is a distressing experience, it is stored as a ‘trauma’ (Vitality Unleashed Psychology, 2024).

The Molecular Basis of Trauma Storage

At the molecular level, trauma appears to affect multiple biological systems simultaneously. One of the most critical molecular findings in PTSD research is that patients exhibit abnormally high GR sensitivity. Central to this finding is the immunophilin Fkpb5 (FK506 binding protein 5), which has become one of the most studied genes in PTSD research (PMC, 2017).

These molecular changes help explain why trauma symptoms can persist even when conscious memory of events may be limited or absent. Emotional memories of traumatic life events are stored in the brain, with anger, grief, worry, stress, and fear often associated with them. Research has now shown that emotional memories, both positive and negative, leave strong impressions on our brains and therefore affect our behaviour (Camino Recovery Spain, 2023).

Physical Trauma and Emotional Integration

The Convergence of Physical and Emotional Pain

When trauma involves both physical injury and emotional distress, the integration of these experiences creates complex neurobiological patterns. A robust body of research demonstrates that prolonged or repeated exposure to stress and trauma can have serious negative consequences for physical and mental health, particularly when stress is experienced early in development (PMC, 2019).

The nervous system doesn’t distinguish between physical and emotional threats in its fundamental alarm responses. Compromised maternal care, including neglect, inconsistency, and lack of sensitivity, is a significant contributor to ELS (early life stress), resulting in increased numbers and function of excitatory synapses upon stress-sensitive neurons in the hypothalamus, a critical structure in coordinating the autonomic response to stress as part of the HPA (Taylor & Francis, 2022).

This helps explain why survivors of physical trauma often experience ongoing emotional and physical symptoms that seem disproportionate to their current circumstances. The body’s alarm system, having been overwhelmed by the combination of physical threat and emotional distress, remains hypervigilant and reactive.

Somatic Processing of Combined Trauma

From a phylogenetically and ontogenetically informed perspective, trauma-related symptomology is conceptualized as grounded in brainstem-level somatic sensory processing dysfunction and its cascading influences on physiological arousal modulation, affect regulation, and higher-order capacities (Frontiers in Neuroscience, 2022).

This understanding suggests that healing from combined physical and emotional trauma requires interventions that address the foundational sensory processing systems. Somatic approaches are particularly well-suited for this integration because they work with the body’s natural capacity for self-regulation and healing.

Somatic Therapy: Working with the Body’s Wisdom

Theoretical Foundations

Somatic therapy emerged from the recognition that traditional talk therapy alone may not be sufficient to address trauma that is stored in the body. Pioneer Peter Levine observed that animals in the wild naturally recover from traumatic experiences through physical discharge and developed Somatic Experiencing based on this observation.

The core principles of somatic therapy include:

Bottom-Up Processing: Rather than starting with cognitive understanding, somatic approaches begin with body sensations and allow awareness to emerge organically.

Window of Tolerance: Developed by Dan Siegel, this concept describes the optimal zone of arousal where healing can occur without overwhelming the nervous system.

Pendulation: The natural movement between states of activation and calm that builds resilience and expands capacity for regulation.

Resource Building: Identifying and strengthening internal and external resources that support nervous system regulation.

The Integration of Polyvagal Theory

Stephen Porges’ Polyvagal Theory provides crucial neurobiological understanding for somatic work. The theory describes three neural circuits:

Social Engagement System (Ventral Vagal Complex): Supports calm, social connection, and optimal functioning
Sympathetic Nervous System: Manages fight-or-flight responses
Dorsal Vagal Complex: Handles immobilization responses, including freeze and collapse

Understanding these systems enables somatic therapists to track client states and intervene effectively. As the body changes, threat detection systems in the primitive brain can be activated. This part of the brain responds strongly to touch, safety, and presence. If a change in the body can be supported, cellular memory can be modified without needing to remember or even understand the traumatic event (Vitality Unleashed Psychology, 2024).

Evidence Base for Somatic Approaches

Research Findings

Multiple studies have demonstrated the effectiveness of somatic trauma therapies:

Somatic Experiencing: A 2017 randomized controlled trial by Brom et al. found that SE was as effective as CBT for PTSD treatment, with particular advantages in reducing physical symptoms and improving quality of life.

Sensorimotor Psychotherapy: Research by Langmuir et al. (2012) showed significant improvements in PTSD symptoms, with powerful effects on intrusive symptoms and emotional numbing.

Body-Based Interventions: A meta-analysis by van der Kolk et al. (2014) found that body-based interventions showed significant promise for trauma treatment, particularly for symptoms that don’t respond well to traditional talk therapy alone.

Neurobiological Validation

Brain imaging studies have shown changes in areas affected by trauma following somatic interventions. Using a combination of advanced genetic tools, 3D electron microscopy, and artificial intelligence, Scripps Research scientists reconstructed a wiring diagram of neurons involved in learning. They identified structural changes to these neurons and their connections at the cellular and subcellular levels (NIH, 2025).

This emerging research on neural plasticity supports the premise of somatic therapy, which suggests that the nervous system can reorganize and heal when provided with appropriate interventions.

Clinical Applications and Techniques

Core Somatic Interventions

Sensation Tracking: Teaching clients to notice and describe body sensations without judgment creates the foundation for somatic awareness.

Grounding Techniques: Helping clients connect with the present moment through physical contact with the earth or floor supports nervous system regulation.

Boundary Work: Exploring physical and energetic boundaries helps clients develop a stronger sense of self and safety.

Movement and Discharge: Encouraging natural movements and impulses supports the completion of interrupted defensive responses.

Integration with Other Modalities

Somatic therapy integrates well with other evidence-based approaches:

EMDR: Eye Movement Desensitization and Reprocessing naturally incorporates bilateral stimulation that supports somatic integration.

Cognitive Processing Therapy: CPT can be enhanced by including body awareness and sensation tracking.

Mindfulness-Based Interventions: These approaches naturally complement somatic work by developing present-moment awareness.

Special Considerations for Different Populations

Cultural Responsiveness

Modern somatic trauma work increasingly recognizes the impact of systemic oppression and collective trauma. This work revealed that experiences, ranging from individual to structural, are embodied, with their effects on the physical body as well as on emotions and cognition (PMC, 2024).

Practitioners must consider:

How different cultures relate to the body and healing
The impact of systemic oppression on nervous system functioning
Accessibility and inclusivity in somatic interventions

Special Populations

Children and Adolescents: Dramatic brain/body transformations occurring during adolescence may provide a highly responsive substrate to external stimuli and lead to trauma-related vulnerability conditions (ScienceDirect, 2023). Somatic approaches for young people must be developmentally appropriate and trauma-informed.

Complex Trauma Survivors: Those with histories of repeated or prolonged trauma may require specialized approaches that build safety and stabilization before processing trauma material.

Advanced Integration: The Alexander Technique and Energy-Based Approaches

Movement Education and Somatic Healing

The Alexander Technique offers valuable integration with somatic trauma work by addressing habitual movement patterns that may perpetuate trauma responses. This method teaches awareness of how we use our bodies and provides tools for conscious choice in movement and posture.

The integration of Alexander principles with somatic trauma work offers several advantages:

Pattern Stabilization: Helping clients maintain nervous system changes achieved in therapy
Conscious Choice: Teaching the ability to pause before falling into old trauma patterns
Functional Integration: Translating healing into improved daily functioning

Energy-Based Integration

Approaches drawn from Reiki, Quantum Touch, and other energy-based modalities can complement somatic trauma work when integrated thoughtfully:

Body Awareness Enhancement: Energy-based hand positions can increase proprioceptive awareness. Nervous System Regulation: Specific breathing patterns combined with gentle touch support parasympathetic activation. Integration Support: Energy-based practices can help anchor and integrate the gains from somatic therapy.

Future Directions and Implications

Emerging Research Areas

Epigenetics: Research on how trauma affects gene expression and how somatic interventions might influence epigenetic changes shows promise for understanding intergenerational trauma transmission and healing.

Collective and Community Trauma: Developing somatic approaches that can address trauma affecting entire communities represents a critical frontier.

Technology Integration: Virtual reality, biofeedback devices, and smartphone applications are now supporting somatic trauma work in innovative ways.

Clinical Integration

The future of trauma treatment lies in integrating somatic approaches with traditional healthcare. Over 70% of individuals experience a traumatic event at least once in their lifetime, with approximately 10% developing posttraumatic stress disorder (PTSD) as a result (NCBI Bookshelf, 2024).

This prevalence underscores the importance of trauma-informed care across all healthcare settings, with somatic approaches offering valuable tools for assessment and intervention.

Implications for Practitioners

Training and Competency

Effective somatic trauma work requires specialized training that includes:

Personal Somatic Work: Practitioners must engage in their own healing to develop the sensitivity required for this work
Supervised Practice: Extensive supervision is essential for developing subtle somatic intervention skills
Ongoing Education: The field continues to evolve, requiring commitment to lifelong learning

Ethical Considerations

Working with trauma stored in the body requires careful attention to:

Informed Consent: Clients must understand the nature of somatic interventions
Boundary Awareness: Touch and body-based interventions require clear boundaries and consent processes
Cultural Sensitivity: Approaches must be adapted to respect diverse cultural perspectives on the body and healing

Practical Recommendations

For Healthcare Providers

Develop Body Awareness: Cultivate your own somatic awareness to better attune to client’s nervous system states
Learn Basic Nervous System Education: Understanding polyvagal theory and window of tolerance concepts enhances all clinical work
Incorporate Simple Somatic Tools: Basic grounding and breathing techniques can be valuable additions to any therapeutic approach
Seek Training: Consider formal training in somatic approaches to enhance your clinical skillset
Build Referral Networks: Develop relationships with qualified somatic practitioners for appropriate referrals

For Trauma Survivors

Explore Body Awareness: Begin noticing body sensations without trying to change them
Practice Grounding: Simple techniques like feeling your feet on the floor can support nervous system regulation
Seek Qualified Practitioners: Look for therapists trained in somatic approaches when traditional talk therapy isn’t sufficient
Be Patient with the Process: Somatic healing often occurs slowly and requires patience with the body’s natural rhythms
Build Resources: Identify activities, people, and places that help you feel calm and regulated

Conclusion

The emerging understanding of cellular memory and the neurobiological basis of trauma storage represents a significant advancement in our approach to healing and recovery. The first step is becoming aware of the experience, identifying it, and understanding that it is not the memory of the trauma itself that hurts you. It is the perception of the trauma you remember that’s hurting you (Vitality Unleashed Psychology, 2024).

Somatic therapy offers hope for those who have not found relief through traditional approaches alone by honoring the body’s role in both storing and healing trauma. As our understanding of the intricate connections between mind, body, and healing continues to evolve, somatic approaches will likely become increasingly central to comprehensive trauma treatment.

The integration of somatic therapy with other evidence-based approaches, including movement education and energy-based practices, opens new possibilities for healing that address trauma at all levels – from cellular memory to conscious awareness. For both practitioners and survivors, this represents an invitation to trust in the body’s innate wisdom and capacity for healing.

The body truly does keep the score, but it also holds the keys to recovery. Through patient, informed, and skillful somatic work, we can help the nervous system complete interrupted responses, discharge stored trauma, and return to its natural capacity for regulation, connection, and resilience.

As we continue to understand trauma’s impact on the whole person – body, mind, and spirit – somatic approaches offer a pathway back to embodied presence, safety, and wholeness. The future of trauma treatment lies not in choosing between mind and body, but in recognizing their fundamental integration and working with both in the service of healing.
