Understanding the Nervous System: Freeze, Fight, Flight, and Fawn
Trauma dysregulates the nervous system, putting us into survival mode. Learn about the four trauma responses and how to recognize which one you default to.
There's a reason it's called "trauma." The word comes from the Greek for "wound"—and a wound requires attention at the deepest level to truly heal.
Traditional talk therapy addresses the mind. But trauma lives in the body. It's stored in your nervous system, your muscles, your breath patterns, your posture. It's in the way you flinch at loud noises, the way you can't relax in certain situations, the way your body remembers what your mind tries to forget.
Somatic therapy recognizes this. It works with the body as the primary site of healing.
What is Somatic Therapy?
Somatic literally means "of the body." Somatic therapy approaches healing by working directly with the nervous system and the physical sensations held in the body.
Rather than asking "What happened?" (the cognitive approach), somatic work asks: - "What do you feel in your body right now?" - "Where do you hold this fear?" - "What does your body need?" - "What wants to move or be expressed?"
How Trauma Lives in the Body
When trauma occurs, your nervous system mobilizes for survival. Your body tenses, your breathing changes, your muscles prepare for fight, flight, or freeze. This activation is adaptive in the moment—it keeps you alive.
But when trauma is unresolved, that activation becomes stuck. Your nervous system remains in a state of threat detection. Your body lives as if the danger is still present.
This manifests as:
- Chronic muscle tension, especially in the jaw, shoulders, and chest - Shallow, restricted breathing - Hypervigilance—your nervous system scanning for danger - Physical pain without medical explanation - Difficulty with touch or physical closeness - Sensations of heaviness, numbness, or disconnection - Startled responses to minor stimuli - Difficulty relaxing or "turning off"
The Somatic Nervous System
Understanding your nervous system is key to understanding somatic healing.
Your sympathetic nervous system is your "accelerator"—it mobilizes you for action (fight, flight). Your parasympathetic nervous system is your "brake"—it calms you and supports rest and digestion.
In trauma, the accelerator gets stuck on. Your body is in a state of chronic activation, even when there's no actual threat.
Somatic work helps shift your nervous system from sympathetic activation back to parasympathetic regulation. This isn't willpower or positive thinking—it's a physiological shift that happens through body-based practice.
Core Principles of Somatic Healing
Bottom-Up Processing
Rather than starting with cognition and trying to think your way to healing, somatic work starts with the body and works upward. This is important because trauma bypasses rational thought—it's stored pre-verbally in the nervous system.
Pendulation
This means noticing the oscillation between areas of activation and areas of ease in your body. A somatic practitioner might guide you to notice: "Feel the tension in your chest, then feel the ground supporting you." This alternation helps the nervous system gradually find balance.
Titration
Titration means working with small amounts of sensation at a time, rather than trying to process everything at once. This prevents overwhelming the nervous system and allows gradual healing.
Tracking
Tracking is the practice of noticing physical sensations in real-time. Rather than talking about feelings, you notice: "I feel a tightness in my throat," "My heart is racing," "There's a heaviness in my legs." This simple practice of noticing is itself therapeutic.
Somatic Practices for Healing
Breath Awareness
Notice your breath without changing it. Many trauma survivors breathe shallowly. Simply becoming aware of your breath pattern is the first step. Over time, deeper breathing naturally develops.
Progressive Muscle Relaxation
Systematically tense and release muscle groups. This helps your nervous system remember what relaxation feels like and gives you agency over your body.
Gentle Movement
Yoga, tai chi, qigong, or simply moving in ways that feel good help complete the defensive movements your body couldn't complete during trauma.
Shaking or Tremoring
Animals shake to release trauma. Humans can too. Allowing your body to shake, tremor, or vibrate is a way of releasing stuck activation. This can feel awkward but is profoundly healing.
Body Scanning
Systematically bringing awareness to different parts of your body, noticing sensations without judgment. This rebuilds the connection between your mind and body.
Authentic Movement
Moving with closed eyes in a contained space, following what wants to move. This bypasses the controlling mind and allows the body's wisdom to express itself.
Touch and Boundary Work
For survivors of physical or sexual trauma, somatic work includes learning to feel safe in your own body and developing healthy boundaries around touch.
Somatic Experiencing
Developed by Peter Levine, Somatic Experiencing (SE) is a specific approach that helps complete the defensive responses that were interrupted during trauma. A practitioner guides you to sense into what wants to happen in your body and allows those movements to complete.
Working with a Somatic Practitioner
While some somatic practices you can do alone, many people benefit from working with a trained practitioner who can:
- Help you notice what you might otherwise miss - Guide you safely through activation and regulation - Provide the relational safety needed for nervous system healing - Teach you practices you can continue on your own
Integrating Somatic Work
Somatic work isn't separate from other healing modalities. It integrates beautifully with:
- Trauma-informed talk therapy - Attachment healing work - Spiritual practice - Medication (when appropriate) - Coaching
The most comprehensive healing addresses all dimensions: the mind (through talk therapy and cognitive work), the body (through somatic practice), the nervous system (through regulation), relationships (through attachment healing), and meaning (through spiritual integration).
A Deep Truth
Your body is not the problem. Your body has been trying to protect you. Every tension, every restriction, every numbing response—these were brilliant solutions to an impossible situation.
Somatic healing isn't about fixing your broken body. It's about gratitude and respect for what your body did to keep you alive, and then, very gently, helping it learn that it's safe now.
Your body carries wisdom. It knows what it needs. Somatic practice is simply the art of listening—to what your body is holding, what it needs, and what wants to be released.
In listening to your body, you rebuild trust with yourself. And in that trust, true healing becomes possible.
