The Biology of Trauma: How Unresolved Emotional Wounds Can Keep You Sick
Introduction
When most people think about toxins, they picture heavy metals, mold, pesticides, or environmental chemicals. But what if one of the most overlooked toxins isn't something you breathe or eat—it's something you experience?
In this powerful conversation, Dr. Pompa sits down with Dr. Amy, author of The Biology of Trauma, to explore how unresolved trauma can become a hidden driver of chronic illness. Together, they explain why the body doesn't distinguish between physical, chemical, and emotional threats, and why healing often requires addressing all three.
Drawing from personal experiences, clinical practice, and neuroscience, they reveal how trauma reshapes the nervous system, influences chronic disease, and—most importantly—how it's possible to rewire those patterns and heal.
Trauma Is More Than a Memory
One of the biggest misconceptions about trauma is that it only applies to catastrophic events.
Dr. Amy explains that trauma isn't defined by what happened—it's defined by how the nervous system experienced it.
Two people can live through the same event and respond very differently. One may recover quickly, while the other carries the effects for decades.
The body records these experiences as survival patterns.
Dr. Pompa relates this to his own life. For years, he dismissed his childhood dyslexia as insignificant compared to other people's struggles. Yet the shame, embarrassment, and fear of being judged quietly shaped many of his behaviors as an adult.
Only later did he realize those emotional wounds had become part of his healing journey.
Trauma isn't about comparing pain. It's about recognizing how unresolved experiences continue to influence your body, your health, and your life.
Trauma Is a Toxin
Throughout the conversation, Dr. Pompa returns to a central idea:
Trauma is a toxin.
Just as the body stores chemical toxins, it can also store unresolved emotional stress.
He explains that chronic illness rarely comes from one event alone. Instead, illness often develops when multiple stressors accumulate until the body's “bucket” overflows.
Those stressors may include:
- Environmental toxins
- Infections
- Nutritional deficiencies
- Chronic stress
- Emotional trauma
When the burden becomes too great, symptoms begin appearing.
Many people describe it the same way:
“I've never felt the same since.”
Often, the final event wasn't the true cause—it was simply the last straw.
A Foster Child Changed Everything
Dr. Amy's understanding of trauma didn't begin in medical school.
It began when she became a foster parent.
She welcomed a four-year-old boy named Miguel into her home after he had spent nearly his entire life in foster care. Because of severe behavioral challenges, he was on the verge of being placed in a group home.
She believed that love, stability, and a safe environment would be enough to help him heal.
Instead, she encountered violent outbursts, intense emotional reactions, and behaviors that seemed completely beyond his control.
Miguel wasn't choosing these reactions.
His nervous system had learned to survive through them.
Watching him transformed Dr. Amy's understanding of trauma.
She realized the body can remain trapped in survival mode long after the danger has passed.
That realization eventually became the foundation of her life's work.
Trauma Lives in Three Places
One of the most valuable insights from the conversation is that trauma isn't stored only in the mind.
According to Dr. Amy, unresolved trauma affects three interconnected systems.
1. The Mind
Trauma shapes beliefs about ourselves and the world.
People often develop deeply rooted beliefs such as:
- I'm not safe.
- I can't trust people.
- I have to do everything myself.
- If people really know me, they'll reject me.
These beliefs quietly influence relationships, careers, and daily decisions.
2. The Body
The body also remembers trauma.
A person involved in a serious car accident may later drive the same road and suddenly experience:
- A racing heart
- Sweaty hands
- Tight muscles
- Shallow breathing
Logically, they know they're safe.
But the body reacts as if the danger is happening again.
The nervous system remembers what the mind has already moved past.
3. Biology
Trauma also affects the body's biology.
When the nervous system believes survival is threatened, it changes how cells function.
Energy production decreases.
Inflammation increases.
Detoxification slows.
Hormones become imbalanced.
Instead of focusing on long-term health, the body prioritizes immediate survival.
Why Chronic Illness Often Appears Years Later
One of the most important distinctions Dr. Amy makes is this:
Trauma itself doesn't necessarily make someone sick.
Unresolved trauma does.
She shares the story of a patient who developed autoimmune disease one year after a car accident.
Initially, it seemed obvious that the accident caused her illness.
But as they explored her history, they discovered years of unresolved childhood fear and chronic stress.
The accident simply pushed an already full stress bucket past its limit.
Dr. Pompa compares it to his “Perfect Storm” model.
Illness rarely results from one isolated factor.
It's usually the combination of physical, chemical, and emotional stress that overwhelms the body's ability to adapt.
The Nervous System Is Always Asking One Question
According to Dr. Amy, the nervous system constantly evaluates a single question:
Am I safe?
If the answer is yes, the body focuses on:
- Healing
- Digestion
- Hormone balance
- Detoxification
- Energy production
If the answer is no, survival becomes the priority.
That's when the body shifts into fight, flight, or freeze.
Unfortunately, many people never fully leave survival mode.
Five Signs You May Be Living in Survival Mode
Dr. Amy identifies several common trauma patterns.
Disconnection
People disconnect from their emotions, bodies, or relationships.
They stay busy, numb uncomfortable feelings, or avoid vulnerability.
Feeling Stuck
Despite wanting change, they sabotage opportunities or struggle to move forward.
The nervous system believes staying small is safer than growing.
Chronic Fatigue
The body conserves energy because it believes resources are limited.
People often feel exhausted no matter how much they sleep.
State Shifting Through Coping Behaviors
Many people unconsciously change their emotional state through:
- Sugar
- Alcohol
- Nicotine
- Overworking
- Excessive exercise
- Constant busyness
These behaviors temporarily relieve emotional discomfort without resolving its source.
Living in Constant Protection
The body remains tense.
Shoulders tighten.
Breathing becomes shallow.
The nervous system never fully relaxes because it still expects danger.
Why Recovery Matters More Than Constant Stress
Dr. Pompa draws an important parallel between healing and athletic training.
Exercise doesn't make people stronger.
Recovery does.
Stress without recovery eventually causes breakdown.
The same principle applies to emotional health.
Growth occurs when the body has enough capacity to recover after stress.
When recovery never happens, the nervous system remains trapped in survival mode.
Healing Starts With Safety
One of the most practical lessons in the conversation is surprisingly simple.
Before working through deep trauma, the body must first experience safety.
Dr. Amy demonstrates this using a somatic exercise.
Rather than trying to think differently, she helps Dr. Pompa notice how placing a pillow across his abdomen immediately creates a feeling of comfort and protection.
His breathing slows.
His shoulders relax.
His body shifts naturally toward safety.
This illustrates an important principle:
Sometimes changing the body's state is more effective than trying to change thoughts alone.
Neuroplasticity Gives Us Hope
Fortunately, trauma isn't permanent.
The brain and nervous system are capable of change through neuroplasticity.
Just as learning to ride a bicycle creates new neural pathways, repeatedly practicing safety creates new patterns within the nervous system.
Over time, the body begins expecting safety instead of danger.
That shift influences:
- Stress resilience
- Emotional regulation
- Physical health
- Energy
- Relationships
Healing becomes a biological process, not simply a mental exercise.
Cortisol Isn't the Enemy
Another myth Dr. Amy challenges is the belief that cortisol is always harmful.
Cortisol is a protective hormone.
During stress, adrenaline rapidly prepares the body for action.
Cortisol then helps regulate inflammation and sustain the stress response.
The problem isn't cortisol itself.
The problem occurs when the body remains stuck in chronic survival mode, causing the normal stress response to become dysregulated.
Rather than trying to suppress cortisol, the goal is to restore the nervous system so it naturally returns to balance.
Practical Takeaways
Healing from trauma doesn't begin by reliving every painful memory.
Instead, it begins by helping the body recognize that the danger has passed.
Some practical principles from the conversation include:
- Recognize that emotional trauma can influence physical health.
- Stop minimizing painful experiences simply because others “had it worse.”
- Notice when you're operating from survival instead of safety.
- Develop healthy ways to shift your nervous system rather than relying on coping behaviors.
- Prioritize recovery just as much as productivity.
- Understand that healing often requires addressing the mind, body, and biology together.
Conclusion
The conversation between Dr. Pompa and Dr. Amy offers an encouraging reminder that healing isn't only about removing toxins or treating symptoms.
Sometimes the greatest obstacle to recovery is a nervous system that never learned it was safe again.
Whether trauma began in childhood, through illness, loss, or life circumstances, the body is capable of change. By addressing emotional wounds alongside physical health, we create the conditions where true healing can take place.
The journey isn't about erasing the past—it's about helping the body realize it no longer has to live there.
