What Is Trauma? Expert-Reviewed Guide (2025)

By Dr. Sharon Dickerson DDS

Short answer: Trauma is your nervous system’s response to overwhelming stress that exceeds your capacity to cope. It’s less about what happened and more about how your body and brain experienced it. The good news: these survival adaptations can heal with the right support.

What Is Trauma? (A 2025 Definition You Can Trust)

Trauma is a whole-person response—mind, body and spirit as well as nervous system, emotions, body, and beliefs—to experiences that felt life-threatening, inescapable, or profoundly unsafe. Instead of “just moving on,” your system stays stuck in protection mode (fight, flight, freeze, or fawn). That’s why symptoms can linger long after the event.

Key signs you might be dealing with trauma:

  • Intrusive memories, nightmares, flashbacks, or feeling “on edge”
  • Avoidance, numbness, shame, irritability, or difficulty concentrating
  • Body-based symptoms like tight chest, gut issues, headaches, sleep problems, chronic pain, and fatigue
  • Shifts in daily functioning: isolation, relationship conflicts, or risky coping behaviors (e.g., substances)
  • Poor relationships or lack of meaningful connectedness in your life.

2025 Takeaway: If your body and brain still feel unsafe, it’s not because you’re “broken”—it’s because your system learned to protect you. That can change.

Types of Trauma

Acute: One-time events (accident, assault, natural disaster)
Chronic: Ongoing stressors (violence, bullying, discrimination, medical trauma)
Complex/Developmental: Early, repeated relational traumas that affect attachment, identity, and trust

Trauma vs. PTSD—What’s the Difference?

Many people experience trauma responses without meeting criteria for PTSD. PTSD is a clinical diagnosis; trauma exists on a spectrum. Whether or not you have a diagnosis, your nervous system can re-learn safety.

What Causes Trauma?

 Trauma isn’t defined by the event itself — it’s defined by what happens inside of you. Many of us move through life carrying unrecognized and therefore un-healed trauma, not because we’re broken, but because our nervous systems did exactly what they needed to survive overwhelming moments.

Trauma can arise from obvious hardships, but it can also come from experiences we dismiss as “no big deal.” A fall that seemed minor, a medical procedure we wanted or needed — even something as routine as an incision — can register as trauma if the body wasn’t able to complete the survival response. When the skin barrier is broken, the body instinctively mobilizes to protect; if that activation doesn’t resolve, the system can stay stuck in a state of vigilance.

What turns an incident into trauma is not the intensity of the event, but the impact on your functioning and your sense of safety in the world. Anything that overwhelms your capacity to cope, connect, or stay grounded can be traumatic, including:

  • Moments that happened too fast, too soon, or without enough support
  • Single-incident shocks or long periods of chronic stress
  • Medical interventions, injuries, or illnesses
  • Experiences of grief, loss, neglect, or identity-based harm
  • Situations that felt inescapable, humiliating, confusing, or chronically unsafe

If something in your past changed how you move through life, how safe you feel in your body, or what you believe about yourself, it’s worth honoring. Your body remembers — and it can heal.


How Healing Works in 2025

Healing is the process of restoring your nervous system’s natural capacity to regulate — to move through different states and reliably return to a grounded, felt sense of safety. When regulation returns, so does your access to joy, curiosity, connection, and the steady inner knowing of who you are.

True trauma healing is not just about reducing symptoms; it’s about reclaiming the parts of you that went offline when life became overwhelming. It’s the restoration of your aliveness, your sense of belonging in your own body, and the solid, trustworthy sense of self that trauma may have fractured.

Because trauma is held in the body, healing often requires bottom-up, body-first support — somatic work, attuned therapeutic touch, and practices that gently guide the nervous system back into coherence. When paired with thoughtful top-down approaches (insight, meaning-making, and cognitive understanding), these methods work together to reset old survival patterns and create new pathways toward ease, resilience, and joy.

Effective, evidence-informed pathways:

  • Somatic therapies (e.g., Somatic Experiencing®, Sensorimotor Psychotherapy, Hakomi)
  • Therapeutic Touch (Coregulating Touch, Craniosacral Therapy)
  • Psychedelic Assisted Psychotherapy Journeys
  • EMDR and parts-informed work like Internal Family Systems (IFS)
  • Trauma-focused CBT and mindfulness
  • Body-based skills (grounding, orienting, breath training, gentle movement)

Supportive basics: sleep, nourishment, time in nature, safe relationships, and nervous-system “micro-resets.”

Why Talk Therapy Sometimes Plateaus — and How Somatic Work Rekindles Real Change

Talk therapy is incredibly valuable for understanding your story, making meaning, and bringing compassion to what you’ve lived through. But insight alone doesn’t always shift the body’s memory of what happened. Many people reach a point where they “understand everything,” yet still feel overwhelmed, numb, anxious, or stuck in patterns they can’t think their way out of.

This isn’t a failure. It’s simply the nervous system saying:
“I need a different kind of support.”

Somatic work helps create the conditions for deeper transformation by engaging the parts of you that talk therapy can’t always reach — your physiology, reflexes, somatic survival patterns, and the implicit memories held in sensation.

Through somatic therapy, you can:

  • Track sensations, impulses, and internal rhythms, not just thoughts — giving the body a voice.
  • Experience co-regulation and titrated exposure, so your system can unwind old activation at a pace that feels safe and doable.
  • Rebuild safety cues from the inside out, allowing your body to trust what your mind already knows.

When the body begins to shift, insight lands differently. Healing becomes embodied — not just understood.

Why Talk Therapy Sometimes Plateaus — and How Somatic Work Rekindles Real Change

  1. Notice now: On a 0–10 scale, how activated or numb are you?
  2. Name it: “I’m at a 7—heart racing and jaw tight,” or “I’m at a 3—foggy and flat.”
  3. Nervous-system nudge (pick one, 60 seconds):
    • Orienting: Look slowly around the room. Name 5 neutral objects.
    • Lengthen the exhale: Inhale gently, then exhale a beat longer.
    • Contact: Press feet into the floor or hold a comforting object.
  4. Re-rate: Did you move even one point toward feeling more steady or solid? If yes, that’s regulation.

Intersectional Safety: Identity, Oppression, and the Body

For many clients—especially queer, trans, BIPOC, or neurodivergent folks—threat isn’t just a past event; it’s a context. Somatic therapy honors how identity-based stress shapes vigilance, trust, and access to safety. Safety isn’t generic; it’s felt and specific to you.

What Co-Regulating Touch & S.A.F.E. EMDR Might Feel Like

Co-regulation is a deeply relational process. Your therapist uses their kind presence and attuned and gentle touch , pacing, posture to help your nervous system settle. The goal isn’t to “fix” you, but to offer a steady, regulated other so your body can remember what safety feels like from the inside out and in a safe relationship. Touch, when used, is always slow, consensual, and grounded in your comfort.

  • S.A.F.E. EMDR (Somatic and Attachment-Focused EMDR) invites you into processing in a way that honors your nervous system’s need for safety and pacing. Instead of pushing through overwhelming material, you move in tolerable, titrated doses, supported by an attuned therapist who’s tracking your physiology moment by moment. This creates room for deeper repair, especially around attachment wounds and early relational trauma.

And always: you are in charge.

Not all clients want or need touch. Consent is active, ongoing, and collaborative. Your body sets the pace, and we follow it together.

When to Seek Help (and When to Seek Urgent Help)

Seek therapy if: symptoms last longer than 4 weeks, impact work/relationships, or you feel stuck replaying or avoiding.

Seek urgent help now if you’re in immediate danger or considering self-harm—use local emergency services or a crisis line right away.

FAQ’s

What is the simplest definition of trauma?

Your body and brain’s protective response to overwhelming stress that didn’t get to finish resolving.

How do I know if I’m experiencing trauma vs. “just stress”?

If symptoms persist (sleep issues, numbness, hypervigilance, intrusive memories) or shrink your life, it’s worth an assessment.

Is PTSD the same as trauma?

PTSD is a diagnosis; trauma responses exist on a spectrum. You can have trauma without PTSD—and still benefit from care.

Can trauma affect the body years later?

Yes. The nervous system can hold protective tension patterns that show up as pain, fatigue, or gut issues. Somatic work helps unwind them.

I’ve done years of talk therapy—why am I still stuck?

Insight helps, but your body may still be signaling threat. Adding somatic and EMDR-based tools often unlocks change.

Does somatic therapy really help trauma?

For many, yes. It targets the physiology of protection, not just thoughts—so safety becomes something you feel, not just understand.

How fast will I see results?

Everyone is different. We set gentle goals, track micro-wins, and adjust pacing so gains are sustainable.

How do I choose the right therapist?

Prioritize training in trauma/somatic care and a good relational fit. STP’s team-based matching reduces “mismatch” risk.
