We often think of trauma as something that begins and ends with us—something that stems from our own experiences and can be processed on an individual level. However, research in the field of epigenetics is revealing a different truth: the effects of trauma may reach far beyond your own life, potentially being passed down through generations. The experiences of our ancestors, their stresses, and even their emotional responses can leave an imprint on our genetic expression, shaping how we respond to stress and trauma today.
What Is Epigenetics?
Epigenetics explores how external factors such as environment, behavior, stress, and even trauma can influence the way our genes are expressed—without altering the DNA itself. In other words, your lifestyle and experiences can modify how your genes function, and these changes can be inherited by your children, and even grandchildren. Unlike genetic mutations, which change the underlying DNA sequence, epigenetic changes involve chemical modifications to the DNA or proteins associated with it, altering the way certain genes are "turned on" or "turned off."
The impact of epigenetics is far-reaching, influencing everything from our physical health to our emotional regulation. What makes this field even more fascinating is its implication that trauma experienced by your parents or grandparents may have a role in how you handle stress today.
How Epigenetics Works: The Bridge Between Genetics and Environment
At the heart of epigenetics are chemical modifications like DNA methylation and histone acetylation. These changes affect how tightly or loosely DNA is wound around histones, the proteins that help organize our genetic material. When DNA is tightly wound, genes become less accessible and are “silenced.” When it is loosely wound, genes are more likely to be expressed. Environmental factors—such as diet, behavior, and stress—can trigger these modifications, impacting how certain genes are expressed.
One example is DNA methylation, a process in which methyl groups attach to specific points on the DNA, silencing gene activity. This can result in either beneficial or harmful effects, depending on the gene involved. Interestingly, these changes don’t stop with you. Studies show that these epigenetic changes can be passed down to future generations, affecting their susceptibility to stress, trauma, and even diseases like cancer, diabetes, and mental health disorders.
How Trauma and Stress Influence Gene Expression
One of the most compelling aspects of epigenetics is its role in how we process trauma. Both maternal stress during pregnancy and paternal stress pre-conception can significantly affect a child's emotional regulation and stress response later in life. For instance, if a pregnant woman experiences high levels of stress, it can lead to changes in the brain development of her unborn child, making them more prone to anxiety, depression, or emotional dysregulation as they grow.
When trauma occurs—whether in childhood or adulthood—our bodies react to protect us. This often involves a disconnection from our authentic selves, a coping mechanism designed to keep us safe. Over time, these protective responses can become ingrained, altering not just how we react to stress, but how we perceive the world. Epigenetic changes help explain why some individuals, despite not experiencing trauma directly, may still carry the emotional and psychological effects of their parents' or even grandparents' trauma. This is known as transgenerational epigenetic inheritance.
Generational Trauma and Its Impacts
When we talk about trauma, we often think in terms of direct experiences—events we lived through or moments we can recall. But what about those traumas that don’t seem to have a clear origin in our lives? Have you ever felt a deep sense of fear, anxiety, or unease but couldn’t trace where it was coming from? It’s possible that these feelings have their roots in a trauma passed down through generations.
In my practice, it’s not uncommon for clients to struggle with identifying the first time they felt a particular emotion or sensation. This is when I gently remind them that the origin of their trauma may go beyond their own lifetime. Trauma can be pre-verbal, originating in the womb, or even further back in ancestral coding. Your body and nervous system are the result of generations of human evolution—along with the achievements of our ancestors, we also inherit traces of their trauma.
Research shows that epigenetic changes linked to trauma can affect brain structures related to memory and emotional regulation, influencing how we respond to stress, trust others, and even engage in relationships. For those who have inherited trauma responses, these effects can make the body feel like an unsafe place, a sensation that can deeply complicate the healing process.
What Does This Mean for Trauma Healing?
When we understand that trauma responses can be genetically inherited, it changes how we approach healing. It’s not just about processing your own experiences—it’s also about acknowledging the emotional imprints of those who came before you. This is why therapies that engage both the mind and body are so effective in trauma recovery.
At Discover The Root, we recognize that healing from trauma often requires an approach that acknowledges the body’s history—both personal and inherited. Compassionate Inquiry, for instance, helps us access these deeper layers, allowing you to reconnect with emotions that may be rooted in generational experiences. Trauma isn’t just something you consciously remember; it’s something your body holds. By acknowledging this, we can gently guide you through the process of reconnecting with your authentic self and releasing inherited emotional burdens.
Reclaiming Your Story
While the concept of inheriting trauma may feel overwhelming, it’s important to remember that just as trauma can be passed down, so can healing. Epigenetics shows us that environmental factors don’t just cause harm—they can also foster recovery. The changes you make in your own life, from managing stress to processing emotional pain, can have ripple effects for future generations.
In understanding how trauma responses may be genetically inherited, we gain insight into the complexities of our emotions and behaviors. It opens the door to more compassionate self-reflection and, ultimately, a deeper sense of healing. You are not just healing for yourself—you are breaking the cycle for those who came before you and those who will come after.
