Trauma and the Body: Understanding How Trauma Lives in Our Physical Selves

Trauma doesn’t just live in our minds—it lives in our bodies. Long after the traumatic event has ended, our physical selves carry the imprint. This shows up as tension, chronic pain, illness, disconnection from physical sensations, and bodies stuck in states of alert or shutdown.

Understanding the body’s role in trauma helps explain symptoms that might otherwise seem mysterious. More importantly, it points toward body-based approaches that can support healing in ways that talk therapy alone sometimes cannot.

The Body Remembers

When we experience trauma, our bodies respond automatically. The nervous system mobilizes for survival—heart racing, muscles tensing, stress hormones flooding. If we’re able to fight or flee successfully, our bodies discharge this energy and return to baseline.

But trauma often involves situations where fighting or fleeing isn’t possible. The survival energy gets activated but can’t be released. It remains stuck in the body, frozen in time.

This is why trauma survivors may feel like the trauma is still happening, even years later. In a very real sense, for the body, it is. The nervous system hasn’t gotten the message that the danger has passed.

Implicit vs. explicit memory

Traumatic memories are often stored differently than ordinary memories:

Explicit memory is what we typically think of as memory—conscious recollections we can narrate: “On Tuesday, I went to the store.”

Implicit memory includes emotional states, body sensations, and procedural memories. These don’t come with timestamps or narratives. They simply activate.

Trauma is often stored implicitly. The body “remembers” through sensations, physical responses, and emotional states—even when the conscious mind has no clear narrative of what happened. This explains why trauma symptoms can arise without conscious memory of trauma, or why body sensations can be overwhelming even when we “know” we’re safe.

How Trauma Affects the Nervous System

The autonomic nervous system

The autonomic nervous system (ANS) regulates our involuntary functions—heart rate, breathing, digestion, arousal. It has three main states:

Ventral vagal (safe and social): The optimal state. We feel calm, connected, and able to engage with others. Our body functions normally.

Sympathetic (fight or flight): Activated when we perceive threat. Heart rate increases, muscles tense, digestion slows. We’re ready for action.

Dorsal vagal (shutdown/freeze): When fight or flight isn’t possible, this ancient system takes over. We freeze, collapse, dissociate. Functions slow dramatically.

Trauma and the nervous system

In healthy functioning, we move fluidly between these states as situations change. After trauma, the nervous system often gets stuck:

Stuck in sympathetic: Chronic anxiety, hypervigilance, difficulty relaxing, insomnia, irritability, racing heart.

Stuck in dorsal vagal: Numbness, dissociation, depression, fatigue, feeling disconnected from life.

Oscillating between extremes: Swinging from hyperarousal to shutdown, without access to the calm, connected middle ground.

The body continues responding as if danger is present because, neurologically, it hasn’t processed that the danger has passed.

Physical Manifestations of Trauma

Trauma affects the body in numerous ways:

Chronic pain

Trauma survivors have higher rates of chronic pain conditions:

• Fibromyalgia
• Chronic headaches and migraines
• Back and neck pain
• Temporomandibular joint (TMJ) disorders
• Pelvic pain

The connection isn’t always straightforward, but chronic nervous system dysregulation, muscle tension, and changes in pain processing all play roles.

Gastrointestinal issues

The gut and brain are intimately connected. Trauma commonly manifests as:

• Irritable bowel syndrome (IBS)
• Chronic nausea
• Digestive difficulties
• Food sensitivities

Stress hormones directly affect gut function, and chronic activation disrupts the digestive system.

Autoimmune conditions

Research shows links between childhood trauma and adult autoimmune diseases:

• Rheumatoid arthritis
• Lupus
• Multiple sclerosis
• Thyroid disorders

Chronic stress affects immune function in complex ways that researchers are still unraveling.

Cardiovascular issues

Prolonged stress affects the cardiovascular system:

• Increased heart disease risk
• Hypertension
• Elevated heart rate

Other physical impacts

• Chronic fatigue
• Sleep disturbances
• Respiratory issues
• Skin conditions
• Hormonal imbalances
• Weakened immune function

The ACE study

The landmark Adverse Childhood Experiences (ACE) study demonstrated clear connections between childhood trauma and adult health outcomes. More ACEs correlate with:

• Higher rates of heart disease, cancer, and liver disease
• Increased mental health disorders
• Higher mortality rates
• Greater healthcare utilization

The body keeps score of early adversity and pays the price across the lifespan.

Disconnection from the Body

Paradoxically, while trauma lives in the body, many survivors are disconnected from physical sensations.

Dissociation

Dissociation—feeling detached from your body, emotions, or surroundings—is a survival response. When the body is in unbearable pain or danger, disconnecting from it makes sense.

But chronic dissociation means living life from a distance, without full access to physical experience or presence.

Numbing

Survivors may learn to numb physical sensations to avoid the pain stored there. This might involve:

• Substance use
• Overwork
• Compulsive behaviors
• Simply not noticing body signals

Loss of interoception

Interoception is the ability to sense internal body states—hunger, fullness, fatigue, emotion. Trauma can impair this capacity, making it hard to know what you’re feeling physically or emotionally.

Living in the head

Many trauma survivors retreat into thinking, disconnected from their physical experience. The body feels unsafe or foreign, so they avoid inhabiting it fully.

The Body as Resource

While trauma lives in the body, so does healing. The body isn’t just where wounds are stored—it’s also a pathway to recovery.

The window of tolerance

The “window of tolerance” describes the optimal zone of nervous system arousal—alert but not overwhelmed, calm but not shut down. Within this window, we can feel, think, and function effectively.

Trauma narrows the window of tolerance. Small triggers push survivors into hyperarousal or shutdown.

The good news: the window can be expanded. Through body-based practices and trauma therapy, survivors can increase their capacity to tolerate distress and stay present.

Completing the survival response

Sometimes healing involves allowing the body to complete responses that were interrupted during trauma. The body may need to:

• Physically push away (fight)
• Move/run (flee)
• Shake, tremble, or release (discharge survival energy)
• Move from freeze into mobilization

These physical completions can release stuck energy and help the body know the threat has passed.

Building body awareness

Recovery often involves developing (or redeveloping) body awareness:

• Noticing physical sensations
• Reconnecting with interoception
• Learning to inhabit the body safely
• Distinguishing past from present body signals

Body-Based Approaches to Healing

Several therapeutic approaches specifically address trauma’s bodily dimensions:

Somatic Experiencing (SE)

Developed by Peter Levine, SE focuses on releasing trauma held in the body. Key elements:

• Tracking body sensations (felt sense)
• Titration—processing in small, manageable doses
• Pendulation—moving between resource and activation
• Completing defensive responses

SE doesn’t require narrating the trauma story in detail. The focus is on body experience.

Sensorimotor Psychotherapy

This approach integrates body awareness into traditional psychotherapy:

• Attention to posture, gesture, and movement
• Working with body memories
• Developing new physical resources
• Processing trauma through body and mind together

Somatic yoga and trauma-sensitive yoga

Yoga can support trauma recovery when adapted for trauma survivors:

• Emphasis on interoception and body awareness
• Choice and control over movements
• No adjustments without consent
• Creating safety in the body

EMDR and Brainspotting

While not exclusively body-based, both EMDR and Brainspotting incorporate the body:

• Tracking body sensations during processing
• Using the body as a gauge for activation
• Processing sensory and somatic material

Movement therapies

Various movement approaches support trauma recovery:

• Dance/movement therapy
• Martial arts (especially trauma-informed)
• Tai chi and qigong
• Mindful movement practices

Breathwork

Since breath is both automatic and controllable, it provides a direct pathway to the nervous system:

• Extending exhales activates the calming parasympathetic system
• Breath awareness builds interoception
• Specific breathwork practices can shift nervous system states

Self-Help Strategies

While professional support is important for trauma, some body-based practices can help:

Grounding

When dysregulated, grounding brings you back to your body and the present:

• Feel your feet on the floor
• Notice points of contact with your chair
• Hold something cold or textured
• Splash cold water on your face

Orienting

Looking around and taking in your environment signals safety to the nervous system:

• Slowly scan the room
• Notice colors, textures, objects
• Remind yourself where you are and that you’re safe

Gentle movement

Moving the body can help discharge survival energy:

• Walking
• Stretching
• Shaking
• Dancing

Self-touch

Comforting touch can activate the social engagement system:

• Place a hand on your heart
• Self-hug
• Rub your arms
• Hold your own hands

Breath regulation

Simple breathing techniques help regulate the nervous system:

• Slow your breathing
• Lengthen exhales
• Practice box breathing (4 counts in, 4 hold, 4 out, 4 hold)

Creating body safety

Learning to feel safe in your body is gradual:

• Start by noticing one body part that feels okay
• Build tolerance slowly
• Use resources (calming images, safe memories) when body awareness becomes overwhelming

Integrating Body and Mind in Healing

Complete trauma healing typically involves both:

• Top-down approaches: Using the thinking brain to process (talk therapy, cognitive work)
• Bottom-up approaches: Working with the body and nervous system directly

Neither alone is sufficient for many trauma survivors. The mind needs to make meaning; the body needs to discharge and regulate.

Effective trauma treatment often integrates both dimensions, recognizing that trauma is held in the whole person—mind, body, and spirit.

Your Body Is Not Your Enemy

If you’ve experienced trauma, your body may feel like the enemy—the source of pain, unwanted sensations, and reminders of what happened. But your body was trying to protect you. The responses that feel problematic now—the hypervigilance, the tension, the shutdown—were survival strategies.

Healing involves befriending your body, not fighting it. Learning to listen to its signals, meet its needs, and help it understand that the danger has passed.

Your body kept you alive. Now it can help you heal.
