Many people carry invisible wounds that did not originate with their own experiences. These emotional scars are passed down through families, shaping behaviors, mental health, and physical well-being across decades. If you are wondering exactly what is intergenerational trauma, you are taking the first crucial step toward healing. Unaddressed pain from previous generations can heavily influence your daily life, relationships, and coping mechanisms.
At ARTS IOP in Canoga Park, CA, we serve as your dedicated partner in treating this deeply rooted pain. Through our comprehensive mental health and addiction treatment programs, we help individuals uncover and heal inherited wounds. We offer Partial Hospitalization Programs (PHP), Intensive Outpatient Programs (IOP), standard outpatient care, and sober living options to support you at every stage of recovery.
What is Intergenerational Trauma?
Understanding what is intergenerational trauma can be a bit complex. To have a full understanding, it’s best to understand the science and psychology behind intergenerational trauma, its historical context, and how it manifests later on.
Historical Context
To fully grasp what is intergenerational trauma, we must look at the major historical events that cause collective emotional injuries. These can include:
- Large-scale tragedies
- Systemic oppression
- Wars
- Forced displacements
These major abuses leave a lasting mark on entire populations. Survivors of these intense experiences often carry profound grief and psychological distress through collective trauma.1
These collective emotional burdens do not simply disappear when the event ends. They become embedded in the cultural and familial narrative. Parents can unconsciously pass their survival behaviors, fears, and stress responses to their children.2 This cultural transmission means that subsequent generations might exhibit symptoms of trauma even if they never experienced the original distressing event firsthand.
Mechanisms of Transmission
Science and psychology offer clear explanations for how these deep emotional scars are handed down. One fascinating area of study is epigenetics. Research shows that severe stress can actually alter how genes are expressed.3 While the DNA sequence remains the same, trauma can change the chemical markers attached to the DNA, making future generations more susceptible to anxiety, depression, and hyper-reactivity.
Attachment theory also plays a major role. Early relationships between parents and children form the foundation for emotional regulation.4 If a parent is traumatized and emotionally unavailable or highly reactive, the child struggles to form a secure attachment. This early instability deeply impacts the child’s future relationships and mental health.
Furthermore, social learning and modeling dictate that children observe and internalize the behaviors of their caregivers. If children grow up watching their parents use hyper-vigilance or substance use to cope with inherited pain, they are highly likely to adopt those same coping mechanisms in adulthood.
Manifestations of Intergenerational Trauma
The effects of inherited pain show up in various ways, often masking themselves as independent mental health or medical issues. Psychologically, individuals might struggle with issues including:5
- Chronic anxiety
- Low self-esteem
- Unexplained depression
- Pervasive sense of grief
They might feel a heavy emotional burden that they cannot connect to any specific event in their own lives. Behavioral patterns are also strongly affected. People dealing with these generational wounds often develop maladaptive coping mechanisms. This includes substance use disorders, self-sabotaging behaviors, and difficulty trusting others.6
Physical health is equally impacted. The chronic stress associated with unhealed familial wounds keeps the nervous system on high alert. Over time, this constant state of fight-or-flight can lead to autoimmune disorders, chronic fatigue, cardiovascular issues, and severe gastrointestinal problems.7
Signs of Intergenerational Trauma and What They May Look Like
Intergenerational trauma does not always look like a single obvious event. In many cases, it shows up through emotional patterns, coping behaviors, relationship struggles, and chronic stress-related health issues that can feel difficult to explain. The table below highlights some common signs and how they may affect daily life.
| Sign | How It May Feel | How It May Affect Daily Life |
|---|---|---|
| Chronic anxiety | A constant sense of tension, unease, or feeling on edge even when there is no clear immediate threat. | This can make it harder to relax, trust stability, or feel safe in everyday situations, relationships, or routines. |
| Low self-esteem | Feeling unworthy, deeply self-critical, or like something is wrong with you without fully knowing why. | Low self-worth can affect boundaries, relationships, career confidence, and the ability to pursue healthy goals. |
| Unexplained depression | Persistent sadness, heaviness, or emotional numbness that may not seem connected to a specific event in your own life. | Depression can lower motivation, reduce hope, and make day-to-day responsibilities feel overwhelming. |
| Pervasive grief | A lingering sense of sorrow, loss, or emotional burden that may feel larger than your own personal story. | This kind of grief can shape identity, mood, and emotional resilience across many parts of life. |
| Difficulty trusting others | Feeling guarded, expecting rejection, or struggling to believe that closeness and safety can coexist. | Trust issues can lead to relationship instability, emotional distance, and repeated patterns of disconnection. |
| Hypervigilance or chronic stress | Feeling like your nervous system is always scanning for danger, conflict, or emotional threat. | Chronic stress can make concentration, sleep, emotional regulation, and physical health harder to maintain over time. |
| Substance use or other maladaptive coping | Turning to alcohol, drugs, or other harmful coping behaviors to numb anxiety, emotional pain, or inherited stress patterns. | These coping strategies may bring temporary relief while reinforcing addiction, emotional avoidance, and repeated family cycles. |
| Self-sabotaging behaviors | Pulling away from healthy opportunities, relationships, or progress because safety or success feels unfamiliar. | Self-sabotage can interfere with healing, stability, and the ability to build a life that feels secure and sustainable. |
| Stress-related physical symptoms | Ongoing fatigue, digestive issues, body tension, or other health symptoms connected to a chronically activated stress response. | Intergenerational trauma can affect the body as well as the mind, contributing to chronic health strain and lower overall well-being. |
These signs do not automatically prove that someone has intergenerational trauma, but recurring emotional, behavioral, and physical patterns across generations can be an important signal that deeper healing work may be needed.

Frequently Asked Questions
How do I know if I have intergenerational trauma?
Recognizing this type of inherited distress can be challenging because the symptoms often mimic other mental health conditions like generalized anxiety, depression, or PTSD. However, you might notice clear, repeating cycles of addiction, abuse, or relational dysfunction across multiple generations of your family tree.8
Can intergenerational trauma be completely cured?
While the term “cured” implies that the past never happened, the intense pain and disruptive symptoms of inherited trauma can absolutely be resolved and managed effectively. The goal of treatment is not to erase your family’s history, but rather to change your relationship with it. Through targeted trauma therapies like EMDR, somatic experiencing, and cognitive behavioral therapy, you can rewire your brain’s trauma responses. Healing means that the past no longer dictates your present behaviors, emotional states, or physical health.
Are certain communities more susceptible to this type of trauma?
Yes, communities that have endured systemic oppression, genocide, slavery, forced relocation, or extended periods of war are highly susceptible to generational trauma. Indigenous populations, descendants of enslaved people, Holocaust survivors and their families, and refugee communities often carry significant collective wounds. Because the original trauma was inflicted on a massive scale and often spanned several generations, the psychological and cultural impact is deeply ingrained. However, it is important to note that any family that has experienced severe domestic violence, profound poverty, or extreme loss can also pass down trauma, regardless of their broader cultural background.
How does epigenetics play a role in passing down trauma?
Epigenetics is the study of how behaviors and environment can cause changes that affect the way your genes work. When an ancestor experiences a highly traumatic event, their body produces a massive stress response. This intense stress can alter epigenetic markers, which influence how the nervous and endocrine systems function. These altered markers can then be passed down to offspring, making the next generation biologically predisposed to higher anxiety levels, heightened stress responses, and a greater vulnerability to mental health disorders.
What role does addiction play in generational trauma?
Addiction is frequently a symptom of untreated generational trauma. When individuals inherit a dysregulated nervous system and overwhelming emotional pain, they often seek external ways to soothe their distress. Drugs and alcohol become a temporary, accessible method to numb inherited anxiety, depression, and hyper-vigilance.
