Demystifying trauma- your brain can change.
Understanding trauma, the nervous system, and the science of what's possible (hint- its hopeful)
There's something I’d like you to know- which is whatever you've been carrying, whether its the anxiety that surfaces at odd moments, the tension that lives in your body, the ways you've learned to make yourself smaller or safer, or the stories you tell yourself about your abilities- none of it means something is wrong with you. It means your brain and nervous system did exactly what they were designed to do, through possibly one of the hardest points in your life, and are still echoing those adaptations.
You may have lived through something that probably shouldn’t have happened the way it did. And the capacity for change that got you here, is the same capacity that can take you somewhere new.
Trauma is more common than most people realise
When people hear the word trauma, they often picture something catastrophic. A single, devastating event with a clear before and after.
This is what we call Big T trauma- experiences like accidents, assault, bereavement, or natural disaster. Events that overwhelm the nervous system in an acute and obviously identifiable way.
But there is another category, and it affects far more people. Small t trauma refers to experiences that may seem ordinary from the outside, but leave a lasting mark on the nervous system all the same. Childhood emotional neglect. Growing up in an unpredictable household. Being consistently misunderstood, criticised, not believed or overlooked. Relationships that felt unsafe. Years of chronic stress with little support.
And then there is perhaps the most overlooked category of all- trauma shaped by absence. The parent who was physically present but emotionally unavailable. The childhood where love was conditional. The times you needed someone to believe you, and they didn't. The attunement that simply never came.
Researchers on Post-Traumatic Growth have noted that PTG can occur following all types of trauma- developmental, relational and attachment-based, as well as physical. The size of the event matters less than the impact it had on the nervous system, and the story it generated about safety, self, and the world.
Have you ever minimised your own experience because it didn't feel big enough to count? Have you found yourself saying it could have been worse- as though pain is a competition?
The nervous system has no hierarchy for suffering. It simply responds to what it perceives as a threat. And sometimes the most chronic, invisible wounds come from what was missing, rather than what occurred.
A normal response to an abnormal situation
Here is something that can shift your understanding considerably- your symptoms are a sign of intelligence.
The anxiety. The hypervigilance. The way you scan a room when you walk in, or brace when a conversation changes tone. The difficulty sleeping, the chronic pain, the sense of never quite being able to rest. These are the outputs of a system that learned, at some point, that the world was a place that required constant monitoring.
Your unconscious mind and nervous system built these patterns to protect you. They are survival mechanisms- adaptive responses your brain generated in the context of threat, whether that threat was loud and sudden, or subtle and ongoing.
Research shows that following trauma, the brain can remain in a heightened state of alertness- with changes in the stress-responsive systems that persist long after the original event. Meaning your nervous system continues responding to stressors as though the original threat is still present.
This is precisely why willpower and logic so rarely shift the symptoms. You can know, consciously, that you're safe, and yet you still feel your heart rate rise, your breath shorten, your body brace. The response isn't coming from the thinking mind. It's coming from a much older, faster system whose only concern is keeping you alive.
It is a brilliant, exhausting, understandable response to circumstances that asked too much of you.
The brain's remarkable capacity to change
For a long time, the medical world assumed that the brain was largely fixed after childhood. That the patterns laid down in early life were more or less permanent. We now know this is incorrect.
Neuroplasticity- the brain's ability to rewire itself in response to experience- is a lifelong quality. Regardless of age, it is possible to reshape the neural pathways that trauma created, by introducing and re-enforcing new, supportive, and regulating experiences over time.
Think of it this way. The patterns your nervous system developed are like well-worn paths through a field. Used repeatedly over years, they become the default route. But the field itself is alive. With the right conditions, new paths can form. The old ones, walked less and less, begin to soften and fade. They become overgrown and inaccessible, while the new paths become easier to walk.
And it isn't only the brain that holds this capacity for change. The body does too.
Bioplasticity refers to the ability of biological systems- including the nervous system, the immune system, and even cellular function- to adapt and reorganise in response to new experiences. Research into the gut-brain axis, the vagus nerve, and the role of the autonomic nervous system in regulating everything from inflammation to heart rate variability has shown that the body is far more responsive to experience than we once understood. Chronic stress and trauma shift these systems into patterns of dysregulation. And chronic safety, when practised, repeated and embodied, can shift them back.
This is why approaches that work at the level of the body matter so much. Breathwork, in particular, directly influences your vagal tone- the measure of how flexibly and efficiently the nervous system can move between states of activation and rest. Each slow, conscious exhale is a biological act of change. Each session that helps the body find regulation is laying down new physiological as well as neural pathways.
The brain and body are in constant conversation. When we work with both, the possibilities expand considerably.
Neuroplasticity works alongside what researchers call neurointegration- which is the brain's capacity to bring together different regions and systems into a more coherent whole. This includes integration between the conscious and unconscious, between the thinking brain and the survival brain, between what the body is holding and what the mind is ready to understand.
Healing, in other words, is a biological process as much as a psychological one. And biology has a great deal of capacity for change.
Beyond recovery- the possibility of growth
Here is where something remarkable can happen.
Research into what happens to people after significant trauma has revealed something that surprised even the scientists studying it. A great many people come through the far side of their trauma with a depth of self-knowledge, connection, and appreciation for life that they describe as transformative.
This is called Post-Traumatic Growth, a concept developed by psychologists Richard Tedeschi and Lawrence Calhoun in the 1990s following years of research with trauma survivors.
Tedeschi and Calhoun identified five domains in which people report this growth: closer and more meaningful relationships with others, the discovery of new possibilities for their life path, a greater appreciation for life itself, a deeper sense of personal strength, and a new relationship with spiritual or existential questions.
The term "growth" is used deliberately- it describes a person developing beyond their previous level of functioning, rather than simply returning to it. There is a quality of positive transformation here, a fundamental shift in how life is experienced and understood.
This doesn’t mean trauma is ever a good thing. It mean however, that the capacity to adapt, to find meaning, and to rebuild is extraordinary, and hopeful, and that sometimes the rebuilding creates something richer than what was there before.
Has there been something in your experience - however painful- that has given you a perspective, a compassion, or a clarity you carry with you? Even something small?
What makes the difference
Growth and recovery are possible. And the research points clearly to what makes the difference.
Approaches that work create, gradually and repeatedly, a felt sense of safety in the body. They engage the unconscious mind, where the patterns live. They work with the nervous system rather than trying to override it. They combine enough challenge to create new learning with enough support that your system can integrate rather than recoil.
For those with more complex or relational trauma histories, recovery often looks like a meaningful reduction in suffering, a significant expansion of what feels possible, and a fundamentally different relationship with the old material. The grip it has on your nervous system, your relationships, and your capacity to live fully can genuinely shift.
This is the territory I work in. Cognitive Hypnotherapy, guided breath re-education,, and nervous system training, regulation and expansion- used together, gently and consistently- offer the brain and body exactly the kind of new experience they need. Safety. Regulation. Capacity. A new story.
The patterns that formed in the context of danger can reform in the context of care.
A final reflection
If you have spent years wondering why you respond the way you do- why certain things trigger you, why your body braces, why rest feels elusive- I hope something in this has helped it make sense.
Your nervous system learned what it learned for a reason. It did its job. Sometimes it continues doing its job, even when the threat has passed. And it has the capacity to learn something new.
The science of neuroplasticity, bioplasticity, and neurointegration, the research on post-traumatic growth, and years of working with women carrying invisible weight all point in the same direction: change is possible. Genuine, lasting, felt-in-the-body change. It could start today, if you are ready.
