Generational Trauma: How the Past Echoes Through the Future
One of my primary personal and professional goals is to build generational health. Building generational health requires ending generational traumas. Generational traumas damage the brain and make it difficult, if not impossible, to be healthy. So what exactly is generational trauma?
Generational trauma — also called intergenerational or transgenerational trauma — is the phenomenon where the impact of a traumatic experience is not limited to those who lived through it, but is carried forward into the lives of their children and grandchildren. This means that people can feel the echoes of events they never directly experienced.
Both lay people and medical professionals are recognizing that trauma is not just psychological — it leaves imprints on the brain, body, and even genes that shape future generations.
Historical Examples of Generational Trauma
-
The Holocaust: Descendants of Holocaust survivors often show higher rates of anxiety, PTSD-like symptoms, and heightened stress hormone reactivity, even though they were born decades later. Studies suggest that the trauma altered stress-response genes in survivors, changes that were passed down to their children.
-
The Dutch Hunger Winter (1944–1945): Pregnant women exposed to famine during WWII gave birth to babies at higher risk of obesity, cardiovascular disease, and depression. Shockingly, their grandchildren also carried some of these risks — showing how a single generation’s suffering can ripple biologically into the future.
-
Slavery and colonization: Communities affected by systemic oppression, racism, and displacement show persistent disparities in health, mental well-being, and resilience, much of which can be traced to unresolved generational trauma.
Everyday Causes of Generational Trauma
Generational trauma is not limited to war or famine. It can also arise from common but deeply damaging family and social dynamics:
-
Substance abuse – Children of addicted parents often grow up in unstable homes, experiencing neglect, emotional unavailability, or abuse. They are also at higher risk of developing addiction themselves.
-
Abuse of any form – Physical, sexual, or emotional abuse reshapes a child’s sense of safety, trust, and self-worth, and these wounds often echo in how they later parent.
-
Neglect – Emotional neglect, where a child’s needs for love and connection are ignored, can be as damaging as overt abuse.
-
Chronic stress or poverty – Living in constant survival mode alters the developing brain, especially in areas tied to decision-making, memory, and emotional regulation.
Prenatal Stress and the Fetus
One of the most powerful — yet often overlooked — pathways of generational trauma begins before birth.
-
Maternal stress hormones like cortisol cross the placenta, influencing fetal brain development, especially in areas related to stress regulation and emotion.
-
Epigenetic changes can “reprogram” how genes work, meaning a baby may be born already more sensitive to stress or prone to mental health challenges.
-
Health outcomes such as low birth weight, preterm birth, and increased risk for anxiety, ADHD, and mood disorders have all been linked to prenatal stress.
Examples:
-
During the Dutch Hunger Winter, babies exposed to maternal stress and famine in utero grew into adults with higher risks of metabolic disease, and their children also carried some of these risks.
-
Research on women pregnant during 9/11 in New York found that their babies had altered cortisol levels years later, showing how a mother’s traumatic stress experience can biologically echo into her child’s life.
In short, trauma doesn’t just affect those alive today — it can imprint on the unborn, shaping future generations before they take their first breath.
Breaking the Cycle
The hopeful side of this story is that generational trauma is not destiny. With awareness, compassion, and proper support, cycles of trauma can be interrupted. Healing tools include:
-
Therapy and trauma-informed care (for individuals and families)
-
Building safe and nurturing environments, especially for children
-
Mind-body practices like mindfulness, yoga, and breathwork that help regulate stress responses
-
Community healing — surround yourself with people that help pull you out of the trauma cycle, rather than sucking you back in.
- Spend time in nature to help heal the nervous system.
- Physical work and activity- trauma lives throughout the nervous system and tissues. Just talking about trauma is not enough. Somatic work is a necessary part of processing and recovering from trauma.
Generational trauma teaches us that the past is never just the past. Whether it comes from world-shaking events like the Holocaust or everyday family struggles like neglect or substance abuse, trauma can ripple across time, shaping biology, behavior, and community. But with the right interventions, healing can also ripple forward, allowing future generations not just to inherit wounds — but resilience.
Cycle breakers are rare beauties that persist and overcome like a flower growing in the desert. Identifying and exposing trauma and abuse is a necessary step to stopping the trauma cycle, and building a stronger foundation for future generations. Cycle breaking requires taking one step at at time. Those steps can vary from becoming sober, therapy, learning emotional regulation, taking care of your health, calling out abuse, ending secrecy and silence, setting boundaries, or ending isolation of abuse victims, letting go of bad habits, building healthy habits, among many others. There is no one path to becoming a cycle breaker. Some roads are longer and harder than others, but they are all worthy of the journey, and easier with a support group.
