Intergenerational Trauma: What It Is, How It's Passed Down, and How to Begin Healing
You may have grown up feeling the weight of something you could not quite name. Perhaps anxiety arrived before you had any reason for it, or grief settled in your chest without a clear source. If this sounds familiar, you might be carrying intergenerational trauma, pain that did not begin with you, but has found its way to you nonetheless.
Understanding intergenerational trauma and mental health is one of the most compassionate things you can do for yourself. It reframes the question from "what is wrong with me?" to "what happened to the people who came before me, and how has that shaped who I am?"
What Is Intergenerational Trauma?
Intergenerational trauma (also called transgenerational or generational trauma) refers to the transmission of trauma-related symptoms, behaviors, and psychological patterns from one generation to the next. It was first identified in research on Holocaust survivors and their children, where clinicians noticed that adult children of survivors displayed trauma symptoms similar to their parents, despite never having experienced the original events themselves (Kellermann, 2013).
Since then, research has expanded significantly. Studies have documented intergenerational trauma in descendants of enslaved people, refugees, Indigenous communities affected by colonization, and survivors of war, famine, and severe childhood adversity (Yehuda & Lehrner, 2018).
The key insight is this: trauma does not always end when a traumatic event ends. Its effects can ripple forward across generations in ways that are both biological and behavioral.
How Is Intergenerational Trauma Passed Down?
There are two primary pathways through which generational trauma cycles are transmitted: epigenetic changes and relational or behavioral patterns.
Biological Transmission: Epigenetics
Epigenetics is the study of how experiences can alter gene expression without changing the genetic code itself. Researchers have found that trauma can leave molecular marks on genes that regulate stress responses, and these marks can be inherited by biological children and grandchildren (Yehuda & Lehrner, 2018).
In a landmark study, Yehuda et al. (2016) found that adult children of Holocaust survivors had measurably different cortisol levels and altered stress hormone regulation compared to Jewish adults whose parents had not experienced the Holocaust. This suggests that the body itself can carry an inherited stress response, even in the absence of direct trauma exposure.
Relational Transmission: Parenting and Attachment
Trauma also passes between generations through relationships. A parent who experienced significant trauma may struggle with emotional regulation, hypervigilance, or emotional numbness. These states directly influence the attachment bond they form with their children.
Attachment theory, developed by Bowlby (1988) and expanded by subsequent researchers, demonstrates that children develop their core sense of safety, self-worth, and emotional regulation through early relationships with caregivers. When a caregiver is persistently anxious, emotionally unavailable, or unable to offer consistent comfort, a child's nervous system adapts accordingly, often in ways that persist into adulthood.
Adverse childhood experiences (ACEs) compound this further. Felitti et al. (1998) found strong, graded relationships between childhood adversity and long-term mental and physical health outcomes, including depression, anxiety, substance use, and chronic illness. When trauma affects one generation's capacity to parent, the next generation's ACE score can rise accordingly.
Signs You May Be Carrying Intergenerational Trauma
Intergenerational trauma does not always look like what we imagine trauma to look like. It can be subtle, woven into everyday patterns of thought and behavior. Some signs include:
Chronic anxiety or hypervigilance that feels disproportionate to your current circumstances
Difficulty trusting others, or patterns of chaotic or avoidant relationships
Persistent shame or low self-worth with no clear origin
Emotional numbness or difficulty identifying your own feelings
Repeating family patterns you promised yourself you would not repeat
A sense of grief or heaviness that belongs to something larger than your own life story
None of these experiences mean something is fundamentally broken in you. They are adaptive responses, often rooted in inherited survival strategies that once protected your family and now need to be gently updated.

Breaking generational trauma cycles is deeply possible work. It is also some of the most meaningful work a person can do, because healing in you changes what gets passed forward to future generations.
1. Name It
Awareness is the first act of healing. Learning about intergenerational trauma and mental health gives language to experiences that may have felt mysterious or shameful. When you understand that your anxiety or relational patterns may have roots outside your own life, you can begin to hold them with curiosity rather than judgment.
2. Work with a Trauma-Informed Therapist
Trauma lives in the body as well as the mind (van der Kolk, 2014). Evidence-based approaches such as somatic therapy, Internal Family Systems (IFS), and EMDR can help you process inherited trauma at a nervous system level.
A therapist who understands intergenerational trauma will help you explore your family history without blame, and distinguish between your own emotional material and what you may have absorbed from those who came before you.
3. Explore Your Family Story
Gently exploring your family's history, with curiosity rather than judgment, can be profoundly healing. This might look like asking older relatives about what life was like for previous generations, researching your cultural or historical context, or engaging in narrative therapy exercises that help you understand the broader arc of your family's story.
Understanding the context of a grandparent's harshness, or a parent's emotional unavailability, does not excuse harm. But it can offer compassion and loosen the grip of shame.
4. Build New Patterns in Your Body
Because intergenerational trauma is stored physiologically, healing often requires somatic (body-based) practices. Mindfulness, breathwork, movement, and yoga can all support nervous system regulation and help your body learn that safety is available in the present moment.
5. Create New Relational Experiences
Secure, consistent relationships, whether with a partner, friend, therapist, or community, are among the most powerful agents of healing. These relationships offer what researchers call "earned security": a new template for what connection can feel like (Bowlby, 1988).
You Are Not the End of the Story
Intergenerational trauma can feel like a sentence passed down through generations. But it is not. Every moment of awareness, every therapy session, every choice to respond differently than the pattern, is a point where the cycle can change.
You do not have to carry what was never yours to carry. And in learning to set it down, you become part of a new story, one that your descendants may inherit instead.
If you are ready to begin exploring this work, reaching out to a trauma-informed therapist is a meaningful first step. Healing is not linear, and it does not have to happen all at once.
