The fear in your body that has no story attached — where did it actually come from?

The shame arrived before you did. That is not a metaphor. That is the most accurate description I have found, after two decades of clinical practice and research into how trauma moves between generations, for what many of my clients are carrying when they first sit with me. The grief with no clear origin. The hypervigilance that no amount of cognitive reframing settles. The inexplicable sense of not being permitted a full life, as though ease would be a kind of betrayal — though of whom, and of what, they cannot say.

My doctoral research examined ancestral trauma transmission through epigenetic, psychological, and environmental pathways. What that research consistently revealed was that the body does not distinguish between what happened to you personally and what was transmitted to you from those who came before. The nervous system carries what the lineage did not fully process. Understanding this is not an academic exercise; it is the starting point of a different kind of healing.

Ancestral trauma — sometimes called generational or intergenerational trauma — refers to patterns of emotional response, behavioural tendency, and physiological reactivity that originate not in your own experience but in unresolved experiences across your family line. The person carrying it often knows, at some level, that what they are holding does not entirely belong to their own story.

How generational wounds travel through the body

Three mechanisms account for most of what I see clinically, and they operate simultaneously.

The first is epigenetic: trauma alters gene expression in ways that affect how the stress response system is calibrated, and these alterations can be inherited. Rachel Yehuda's research at the Icahn School of Medicine at Mount Sinai documented altered cortisol regulation and measurable differences in FKBP5 gene methylation in the adult children of Holocaust survivors — changes that could not be attributed to the children's own life experience. Trauma leaves a molecular signature that the next generation inherits. Not a metaphor. A physical substrate.

The second mechanism is psychological. The parenting styles, attachment patterns, and emotional responses of adults who carry unresolved trauma shape the nervous system development of the children in their care — not through deliberate transmission but through the ordinary relational environment. A parent whose threat-detection circuitry was sensitised by early experience creates a different developmental container than one whose system was not. The child adapts to that container. What the child adapts to becomes, eventually, what they carry.

The third pathway is cultural and narrative. Families transmit their interpretations of experience — what fear is appropriate, what ambition is permitted, what loyalty requires — through the stories they tell and, more powerfully, through the ones they do not. A woman I worked with spent fifteen years in therapy addressing what had been named as her anxiety. When we began looking at her lineage, what emerged was a pattern of women across three generations for whom visible confidence had attracted danger. Her anxiety was not a disorder. It was an inherited survival strategy, still running in her nervous system long after the conditions that had generated it had passed. These inherited frameworks operate as background assumptions rather than explicit beliefs. That is precisely what makes them so difficult to surface through ordinary reflection.

What it looks like when it's not yours

The presentations I most commonly encounter in clients for whom ancestral work becomes relevant are specific. Emotional responses that feel disproportionate to their actual cause — a reaction that is accurate in its intensity but misaligned with what triggered it. Chronic physical tension, particularly in the chest, throat, and lower abdomen, that persists despite direct somatic treatment. A quality of loyalty to struggle that operates as though ease would be a betrayal; as though things going well is the state that requires vigilance. And a felt sense of carrying something that belongs to more than one life.

These are not pathological. They are signatures of a nervous system shaped by more than one generation's experience. The appropriate response to a transmitted survival pattern is not more self-improvement. It is recognition — and then a different kind of work.

If you are recognising something in this — if there is a quality of response in you that has never quite tracked with your own personal history — a free 20-minute conversation is the most direct next step. Not to explain it, but to help you locate it. You can book that here.

How the healing of ancestral wounds actually works

Ancestral trauma can be addressed through family constellation work, somatic trauma release, and breathwork practices that interrupt the transmission cycle at the level of the nervous system and the body. These modalities are not interchangeable; they address different layers of the same inheritance.

Family constellation therapy, developed by Bert Hellinger and considerably extended by subsequent practitioners, provides a systemic method for surfacing the entanglements within a lineage that are not accessible through direct conversation. A constellation makes the dynamics of a family system — including events that occurred before the client was born — available for direct investigation and, through the process, for resolution. It operates primarily through the body's responses to systemic representation rather than through cognitive reframing. The mind does not need to understand it for the body to process it.

Somatic trauma release — working with the body's physical holding patterns through tremoring, breath, and movement — addresses the physiological layer directly. The tremoring response is a natural neurological discharge mechanism; inhibiting it, as most social environments require, is what produces the chronic muscular and fascial holding that becomes the body's form of memory. Allowing it to complete, in a supported setting, produces genuine discharge. Not catharsis. Discharge. There is a difference.

Breathwork that sustains a full respiratory cycle — deep, connected breathing held for twelve to fifteen minutes without pause — reliably surfaces pre-verbal and pre-personal material. It is not unusual for it to produce grief, imagery, or physical sensation that clients describe as clearly ancestral in character. Whether or not one adopts that interpretive frame, the material that emerges is real and the discharge is genuine.

In my own practice, I combine these approaches with shamanic lineage work — ceremony and intentional ritual that address the relational dimension of ancestral transmission directly. Healing the relationship with one's lineage changes the internal relational environment. That change alters the nervous system's regulatory set point in ways that other approaches alone do not always reach.

Healing ancestral wounds does not require knowing the full history of your family line, though what is discoverable is worth pursuing. What it requires is a willingness to approach what the body holds without insisting that it have a logical personal explanation. The patterns that do not belong only to you will not be fully released by working only with what is yours.

I have written separately about the specific process of clearing inherited material — what the work looks like across its three concurrent tracks, and what shifts when it begins to take hold. That piece, on clearing inherited trauma, approaches the same ground from the angle of practice rather than understanding, and the two are worth reading together.

Your Lineage Ends Here. Your Healing Begins Now.

Is there a moment you can point to where you first understood that what you were carrying wasn't entirely yours?
