Trauma: what remains when the danger is over
You may never have used the word trauma to talk about yourself. Nothing that bad happened to you, you think. Others had it worse.
And yet a slammed door leaves your heart pounding for a good while. You find it hard to trust, or you trust the wrong people. You go quiet exactly when you most wanted to speak. Your body reacts to things your head knows are not dangerous.
That is not exaggeration or weakness. It is a nervous system that learned something at a difficult moment and keeps applying it, even though that moment is over.
What trauma is
The word comes from Greek and means wound.
The physician Gabor Maté sums it up in one sentence: trauma is not what happens to you, but what happens inside you. And he gives a simple example. In a car accident, the crash is what happened; the concussion is what stays.
In Waking the Tiger, Peter Levine approaches it through physiology: symptoms are not caused by the event itself, but by the energy the body mobilized to defend itself and never finished discharging.
That is why the same accident can leave one person intact and another with years of insomnia. What decides it is not only the size of what happened. Age matters, whether you could move or defend yourself, whether someone was with you before and after, how much exhaustion or fear you were already carrying.
Trauma is something that happened too fast. Too fast for the body to process it, and often without the company it needed to be held.
What happened and what didn't
There are wounds from things that happened: an accident, a surgery, an assault, a disaster, a sudden loss, a birth that went wrong. These are the ones almost all of us imagine when we hear the word.
And there are wounds from things that didn't happen. A child who wasn't seen. Who had to look after their parents instead of being looked after. Who learned that their anger, their sadness or their joy had no place at home. Maté calls these small-t traumas. They leave no event to remember, and that is why the people who carry them often feel they have no right to their own distress.
There are also traumas that build up in silence: years of living on alert in a violent or unpredictable home, in an unsafe neighborhood, in a job where nothing is ever enough. There is no single day to point to. There is a body that kept adjusting.
None of these forms is worse than another by definition. Comparing doesn't help much. What matters is what it left in you.
What trauma is not
It is not everything that hurts. A loss, a breakup, being fired can be devastating and leave no trauma. Maté offers a useful criterion: something was traumatic if it left you diminished, more limited than before, in a way that persists. All trauma is stressful; not all stress is traumatic.
It is not weakness or a character flaw. Freezing in the face of a threat is not a decision. It is an automatic, ancient response that often protects life. It has nothing to do with cowardice or with having agreed to anything.
It doesn't depend on remembering. There are traumas from before we had words, from hospital stays or medical procedures in childhood, from periods memory didn't keep. The body registers even when the mind doesn't have the whole story.
It is not the same as post-traumatic stress. Post-traumatic stress disorder is a specific diagnosis, with defined criteria. Trauma is a much wider field, and most of its effects never reach that diagnosis.
It is not a life sentence. A response that was left unfinished is not irreversible damage. Levine insists that within the symptoms themselves are the forces to transform them. A nervous system that learned to defend itself can also learn to rest.
How it changes the way you read the world
Your nervous system is constantly assessing whether what surrounds you is safe, dangerous or life-threatening. It does this below awareness, before you think anything. The researcher Stephen Porges called this process neuroception. By the time you realize someone doesn't feel trustworthy, your body has already decided: your breathing changed, your shoulders moved.
Trauma recalibrates that detector. A system that learned to see danger keeps seeing it where it no longer is.
So a serious face reads as anger. An unanswered message, as rejection. A silence, as punishment. A raised voice, as the beginning of something we already know. It is not that you misread things by choice. The body reacts first, the mind finds out afterwards and then makes up an explanation.
The alert also looks inward. Your own racing heartbeat, the excitement of something good, even a coffee can feel like a danger signal. You search outside for a threat that doesn't appear, because the activation is inside.
And there is a hard paradox: the same system that sees danger everywhere sometimes fails to see it where it really is. Someone who grew up with threat as something normal may not recognize it as an adult.
When activation exceeds what you can hold, the part of the brain that reflects, that weighs things, that can consider another possibility, also goes offline. Daniel Siegel describes this precisely. That is why reasonable advice sometimes doesn't get through. It isn't stubbornness. In that moment there is nothing to receive it with.
Over time, the world shrinks. You avoid places, conversations, people, sensations. You take fewer risks. Life organizes itself, without anyone deciding it, around never feeling that again.
The consequences for your health
A body that stayed on alert pays the cost of living that way. The heart works overtime, sleep turns light, digestion stops again and again, the immune system gets mixed signals, pain is amplified. It is the wear and tear the neuroendocrinologist Bruce McEwen called allostatic load, which I explain in more detail on the somatic therapy page.
The strongest evidence we have comes from a study that wasn't looking for trauma. In the 1990s, the physicians Vincent Felitti and Robert Anda asked more than 17,000 adults seen at Kaiser Permanente in San Diego about adverse experiences in their childhood: abuse, neglect, violence at home, parents with addictions or mental illness, separations. They were middle-class people, most of them with a university education and health insurance.
Only a third had experienced none. And the more adverse experiences a person reported, the higher their risk as an adult of depression, suicide attempts, alcoholism and smoking. Also of coronary heart disease, chronic lung disease and liver disease.
Two things matter about that study. First: what happens in childhood doesn't stay in psychology; it reaches the heart, the lungs, the liver. Second: a high score is not destiny. It is a statistical risk in a population, not a sentence for a person.
The same researchers noticed something that changes the way you look at a patient. Many behaviors medicine treats as the problem, overeating, smoking, drinking, were once a solution: the way a nervous system found to calm itself when it had no other.
Gabor Maté, who worked for years with people with addictions, puts it as a question: don't ask why the addiction, ask why the pain. Maté goes further and argues that being unable to say no ends up making the body ill. Some of these ideas are still debated. What is no longer in doubt is that sustained stress has a real physical cost.
The consequences for your relationships
The nervous system is formed in relationship. A baby can't calm down alone: it calms down in the arms of someone who is more or less calm. That is how we learn, before we have words, what it feels like to be safe with another person. Or that being with another person isn't safe.
That lesson travels into adult life.
Maté describes a tension many children resolve the same way. Between being authentic and keeping the bond with the people who care for them, they choose the bond. They hide what isn't welcome so as not to lose love. As adults they keep doing it: they say yes when they mean no, they adapt until they disappear, or they leave before they can be left.
In couples, many fights are two nervous systems defending themselves at the same time. One raises their voice because they feel threatened. The other goes quiet, not out of indifference or to punish, but because they froze. Neither is talking to the person in front of them. Both are responding to something older.
That is also why relationships repeat. It isn't bad luck. The familiar, even when it hurts, is more predictable than the unknown, and for a body on alert, predictable looks a lot like safe.
Intimacy asks for something a traumatized body finds hard: staying still close to another person without sensing danger. Porges describes it as immobility without fear. For someone who learned that staying still meant being defenseless, closeness can feel like a threat, even when it is exactly what they long for.
And it passes from one generation to the next. Our children don't learn to regulate from what we tell them, but from the state of our nervous system when they are with us.
The good news comes from the same place. If the wound happened in relationship, the repair also happens in relationship. It's not only about knowing; it's about feeling, and being felt.
What can be done
It is not about forgetting what happened or understanding it better. Many people already understand it perfectly. It is about letting the body finish what was left unfinished, at a pace it can sustain, and recover its capacity to activate and come back.
That is the work of somatic therapy. Here I explain how it works and what a session is like.
Frequently asked questions
Can I have trauma even if I don't remember anything serious?
Yes. Many wounds come from what was missing more than from what happened, or from periods memory didn't keep. The body can show the effect even when there is no clear story.
Is trauma the same as post-traumatic stress?
No. Post-traumatic stress is a diagnosis with specific criteria. Trauma is broader and can show up as anxiety, insomnia, pain, digestive problems, difficulties in relationships or a sense of disconnection, without reaching that diagnosis.
How do I know whether what I'm going through has to do with trauma?
There is no checklist that can decide it for you. Some clues: reactions more intense than the situation calls for, a body that doesn't rest even when life is calm, patterns that repeat even though you already understand them. The most useful thing is to talk it over with someone who knows the subject.
Do I have to talk about what happened to me?
No. There are ways of working that don't require narrating or reliving the event. We work with what the body registers, at your pace.
Can trauma be overcome?
I'm not going to promise you it disappears. What I often see in my clinical experience is that it stops being in charge: the body regains room, reactions turn down in volume, and the story becomes something that happened instead of something that keeps happening.
