Intergenerational Trauma in Latino Families: What It Is and How Therapy Helps

Your grandmother never talked about the things she survived. Your parents learned to cope by not coping — by working harder, by staying quiet, by making sure the children had opportunities even when asking for help would have made everything easier. And somewhere in that chain, you ended up carrying weight you didn’t choose and can’t always name. That’s intergenerational trauma. And it is not a metaphor — it has measurable biological and psychological mechanisms that researchers have been documenting for decades.

The Biology and Psychology of Transmission

Intergenerational trauma — also called transgenerational or historical trauma — refers to the transmission of trauma’s effects across generations, even to individuals who did not directly experience the original events. The mechanisms are both biological and psychological.

On the biological side, research from Dr. Rachel Yehuda’s lab at the Icahn School of Medicine at Mount Sinai showed that children of Holocaust survivors had measurably different cortisol levels and stress response profiles than comparable populations — without having experienced trauma themselves. Her team’s follow-up epigenetic research found that trauma changes gene expression: not the genes themselves, but which genes are turned on or off. These epigenetic changes can be inherited, affecting how the next generation’s nervous system responds to stress before they’ve even had a personal reason to be afraid.

On the psychological side, traumatized parents often parent through the lens of their trauma — hypervigilance, emotional unavailability, difficulty tolerating their children’s distress, or over-enmeshment driven by their own unresolved fear. Children absorb the emotional texture of these patterns and organize their own nervous systems around them. Family stories, spoken and unspoken, also transmit information about what’s safe, who can be trusted, what’s worth hoping for, and how to survive. Children receive all of it.

The Specific Context of Latino Intergenerational Trauma

Latino communities in the United States carry specific historical traumas that feed intergenerational transmission: colonial trauma and land dispossession for Mexican-American families whose ancestors lived through the aftermath of the Treaty of Guadalupe Hidalgo; migration trauma including dangerous border crossings, family separation, and detention; labor exploitation across generations of agricultural, domestic, and construction work under conditions of legal vulnerability; and political violence in countries of origin, particularly for Central American families who fled civil wars and state persecution in El Salvador, Guatemala, and Nicaragua during the 1970s through 1990s.

None of these traumas ended cleanly. They exist in family histories, in bodies, in parenting styles, in the financial precarity that shapes daily decisions, and in the chronic low-level hypervigilance of communities that have learned to be wary of institutions and authorities.

Signs That Intergenerational Trauma May Be Part of Your Picture

Anxiety or hypervigilance that feels disproportionate to your actual current circumstances. Shame or low self-worth that doesn’t correspond to anything specific in your own history. Difficulty trusting authorities or institutions even when you have no direct personal reason not to. A sense that you need to earn your right to be safe or happy. Patterns in your relationships that mirror your family of origin’s dynamics — even when you’ve consciously tried to do things differently. An obligation to family that feels impossible to set any limits on. Hypervigilance about your children’s safety that may be anxiety-driven more than circumstance-driven.

What Therapy Does with It

Therapy for intergenerational trauma doesn’t try to undo history. It works with what that history deposited in your nervous system, your self-concept, and your relational patterns. This typically involves mapping the family trauma history clearly — understanding what happened, who carried it, and how it was transmitted. Differentiating your own trauma responses from those you inherited. Processing the grief of growing up in a traumatized family system. Addressing current PTSD or complex PTSD symptoms rooted in the early family environment. And building new relational and coping patterns that aren’t organized around the old trauma logic.

A bilingual, bicultural therapist is not optional for this work — it is important. At Xola Counseling, Yenit Jiménez-Balderas, LPC brings both clinical training in trauma therapy and personal cultural understanding of the Latino family experience to this work. You don’t have to explain the context from scratch. The landscape is already understood.
