How Trauma Affects the Nervous System (and What Therapy Can Do)
Understanding Why Your Body Reacts the Way It Does and How Therapy Can Help You Regulate and Heal
Trauma isn’t just something we “think” about. It impacts our entire being, especially the nervous system.
If you've ever felt frozen in place, stuck in survival mode, or reactive in ways you don't fully understand, you're not broken. You're responding in exactly the way your nervous system was designed to protect you.
At Tidal Trauma Centre in Surrey, we specialize in therapy that supports nervous system regulation after trauma. Whether you’ve experienced a single overwhelming event or years of chronic stress, your body’s responses make sense and they can be supported to shift with time, care, and the right approach.
Why Your Body Reacts the Way It Does
Trauma activates your nervous system in profound and often invisible ways. You might feel:
Panicky or overstimulated (fight or flight)
Spaced out, foggy, or numb (freeze)
Compliant or overly accommodating, even when it doesn’t feel right (fawn)
These are not personality flaws. They are survival responses that form when our systems sense threat, real or remembered, and they can stay with us long after the original danger has passed.
When trauma is unresolved, your nervous system may react to safe or neutral situations as though they are dangerous. You may notice this in your relationships, your physical health, your decision-making, or your ability to rest. Therapy helps make sense of these patterns and gently support your system back toward balance.
Trauma Isn’t “All in Your Head”
The effects of trauma ripple through the brain, body, and emotional landscape. Here’s what that can look like:
Brain
Difficulty focusing or remembering
Hypervigilance or overanalyzing
Emotional reactivity or shutdown
Body
Chronic tension or pain
Digestive issues or fatigue
Sensations of being "on edge" without knowing why
Emotions
Outbursts of anger or grief
Sudden disconnection or apathy
Ongoing anxiety or dread
Understanding this physiological impact is often the first step toward reclaiming self-trust. What may feel irrational on the surface is often a deeply logical response when seen through a nervous system lens.
How Therapy Supports Nervous System Healing
Trauma-informed therapy doesn’t just help you “talk through it”, it helps you feel through it, in a way that’s paced, safe, and supported. Nervous system-focused therapy supports you to:
Track your nervous system states and learn when you’re in fight, flight, freeze, or fawn
Develop more tolerance for uncomfortable sensations without becoming overwhelmed
Use breath, posture, language, and rhythm to bring your system back into connection
Build safety through boundaries, self-awareness, and relational repair
With time, you may notice more choice in how you respond to stress, more access to joy and connection, and a sense of being more at home in your own body.
Modalities That Help
Healing the nervous system requires an integrated approach. At Tidal Trauma Centre, we use a blend of evidence-based, body-informed therapies to meet each client where they are:
EMDR (Eye Movement Desensitization and Reprocessing) helps the brain reprocess stuck or “frozen” traumatic memories. It’s particularly effective for relieving emotional intensity, intrusive thoughts, and physiological triggers linked to past experiences.
Internal Family Systems (IFS) helps you get to know the protective parts of your psyche that have carried fear, vigilance, or shame. By building relationships with these parts, you begin to cultivate more internal compassion, stability, and access to your core Self.
Somatic Experiencing & Sensorimotor Therapy work directly with the body’s physiology. You’ll be supported to track sensations, notice micro-movements, and build nervous system capacity, often without needing to talk through the traumatic event itself. This can be especially helpful for those who have felt overwhelmed or shut down in other types of therapy.

This is often the "freeze" or "shutdown" response, your nervous system’s way of protecting you when it perceives no safe escape. It’s especially common in those with childhood trauma or high-stress environments. With the right therapy, you can begin to recognize and shift these states.
-
Dysregulation refers to being stuck in either overactivation (panic, anxiety, hypervigilance) or underactivation (numbness, exhaustion, fog). It’s not a weakness, it’s a pattern your body adopted to cope. Nervous system-based therapy helps you find steadiness and choice again.
-
Yes. Trauma can show up as chronic pain, gut issues, tension, and more. These are often messages from the body asking for support. Somatic therapy gently works with these messages so they can be integrated, not ignored.
-
We listen to both your words and your nervous system. We don’t force, rush, or retraumatize. Our approach includes titration (working in small doses), consent, pacing, and co-regulation. It’s therapy with your body, not against it.
-
Not necessarily. Many of our clients experience deep healing through sensation, movement, and parts work without retelling the entire story. Safety and connection matter more than disclosure.
-
It depends. Some clients feel relief within a few sessions, while others engage in longer-term work. We move at the pace of your nervous system, not the pressure of productivity.
