Different Types of Trauma and How They Impact Mental Health

Trauma isn’t always about visible wounds—it’s often an emotional response to distressing or overwhelming experiences. Whether it’s a single shocking event or something that builds over time, the impact can shape how we think, feel, and relate to the world around us. And here’s the truth: it doesn’t look the same for everyone.

Recognizing the different forms it can take is an important step in understanding what you—or someone you care about—might be facing. It can help explain intense emotional reactions, recurring patterns, or even physical symptoms that seem to come out of nowhere.

In this blog, we’ll explore how these experiences can affect your mental and emotional well-being. Because the more we understand, the better prepared we are to heal—and to seek the support we deserve when we need it.

What is trauma?

Emotional fallout from distressing or overwhelming experiences can leave a lasting mark, especially when those moments make you feel unsafe, powerless, or deeply unsettled. It doesn’t always take a dramatic event; even ongoing or subtle stressors can have a powerful effect. Everyone responds differently, which is why it’s important to recognize the many forms these experiences can take.

What are the 3 main types of trauma?

Acute

Single, overwhelming events can cause intense emotional distress. It’s often sudden and unexpected, shaking your sense of safety and leaving a strong emotional imprint. The brain may go into survival mode, and it can be hard to process what happened, even long after the event has passed.

Examples can include:

  • Violent or sexual assault
  • Life-threatening illness or serious injury
  • The sudden loss of a loved one
  • Witnessing a violent act
  • Being a victim of a crime or a serious accident
  • Natural disasters like earthquakes or fires
  • Complications during childbirth
  • Surviving a suicide attempt

People may experience flashbacks, anxiety, avoidance, or other symptoms for years that is tied to that one event.

Chronic 

Repeated or prolonged exposure to distressing events can have a lasting emotional impact. Instead of one single moment, it’s the ongoing nature of the experience that causes harm. When someone is exposed to high levels of stress or danger over time, the brain and body may remain in a near-constant state of alert, which takes a serious toll on mental and physical health.

Some examples include:

  • Domestic violence
  • Bullying (in school, at work, or online)
  • Long-term or terminal illness
  • Repeated physical, emotional, or sexual abuse

Children and adults who live through these types of experiences often develop coping mechanisms to survive the environment they’re in, like emotional numbing, dissociation, or hypervigilance. However, these survival strategies can become detrimental to daily life and relationships over time.

Complex

Complex trauma is usually the result of exposure to multiple emotionally painful events, often of an invasive and interpersonal nature. It tends to occur during early development and is often associated with situations where a person, especially a child, feels stuck, unsafe, or powerless for extended periods of time. This can deeply impact a person’s sense of self, relationships, and ability to regulate emotions.

These experiences include:

  • Childhood abuse (physical, emotional, or sexual)
  • Chronic neglect
  • Inconsistent caregiving and attachment issues
  • Religious or spiritual abuse
  • Growing up in an overly strict, controlling, or fear-based environment

Because it happens early in life, it can affect how a person sees the world, connects to others, and relates to themselves. It’s not uncommon for people with complex trauma to struggle with identity, boundaries, emotional regulation, or forming safe relationships.

Big t and little t

Big t trauma

This category includes the impact from major, often life-threatening events that cause intense psychological and emotional distress; events that are sudden, overwhelming, and impossible to ignore. It is often linked to post-traumatic stress disorder (PTSD) and can leave a lasting impact on someone’s ability to feel safe or in control.

Some examples include:

  • Natural disasters
  • War or combat
  • Severe accidents or injuries
  • Sexual assault or abuse
  • Life-threatening experiences

Big t experiences are typically categorized as acute, but they can also be part of ongoing or deeply rooted emotional distress, especially when events are repeated or occur during critical stages of development.

Little t trauma

This refers to less obvious but still emotionally painful experiences. These situations may not seem apparent from the outside, but they can have a profound impact on a person’s mental and emotional well-being, especially if they occur repeatedly or during a vulnerable period in life.

Examples of this include:

  • Bullying
  • Emotional abuse or neglect
  • Divorce or parental conflict
  • Loss of a pet
  • Academic or social pressure

Less obvious emotional wounds can overlap with ongoing or deeply rooted emotional distress, and when left unaddressed, they can lead to long-term effects similar to those caused by more intense experiences.

Generational

Unresolved struggles from the past don’t just fade—they can leave a lasting mark on families. These deep-rooted experiences often shape family dynamics, influence belief systems, and impact mental health in subtle but powerful ways.

This kind of inherited pain often stems from large-scale historical or cultural events that affect entire communities. Even if someone didn’t directly live through those events, they may still carry the emotional weight or learned responses of those who did.

Examples include:

  • Cultural oppression
  • Racism and systemic discrimination
  • Genocide
  • Forced migration or displacement
  • Historical harm from colonization or slavery

Families impacted by these experiences may struggle with trust, emotional regulation, or a constant sense of threat, effects that can continue long after the original events have passed.

Recent research in the field of epigenetics suggests that psychological injury can actually alter how the body responds to stress, and that these changes may be passed down within families. One study on Holocaust survivors and their children found that disruptions in stress hormone regulation appeared in both parent and child. This suggests that these experiences don’t just impact our emotions and mental health—they can also leave a mark on our biology.

Understanding this type of inherited impact helps explain why some emotional wounds run so deep. But to truly get to the root, we also need to explore how these experiences influence development, especially during childhood.

Developmental

Distressing experiences that occur during a child’s most formative years can have a huge impact, especially when they are still learning how to bond, connect, and understand the world around them. Experiences that disrupt emotional, cognitive, and social development during these critical stages can shape how a person views themselves, others, and their environment well into adulthood.

Unlike a single overwhelming incident, it stems from repeated exposure to harmful, unstable, or neglectful conditions over time. The effects may not always be visible on the outside, but they can influence how a child learns, manages emotions, and builds relationships, often carrying over into later life.

Examples include:

  • Chronic neglect
  • Disruptions in attachment (such as inconsistent caregiving or frequent changes in caregivers)
  • Exposure to domestic violence or substance abuse in the home
  • Physical, emotional, or sexual abuse
  • Being raised in a chaotic or unsafe environment

Children may struggle with emotional regulation, have trouble letting others in, or seem “hyper-independent” or emotionally shut down. These are often coping mechanisms developed to survive early adversity.

Because these experiences happen so early in life, their effects can be deeply rooted—but with the right support, healing is absolutely possible.

What can trauma do to a person?

Trauma doesn’t always show up in obvious ways. Sometimes, it’s visible, like panic attacks or emotional outbursts. Other times, it’s quiet, lingering in the background through constant fatigue, emotional numbness, or a sense that something isn’t right. The truth is that it can affect every part of a person’s life—how they think, feel, sleep, interact with others, and even how their body functions.

Unresolved pain doesn’t always show up in obvious ways. Sometimes, the effects are visible, like panic attacks or emotional outbursts. Other times, the impact is quieter, lingering in the background as constant fatigue, emotional numbness, or an unshakable sense that something isn’t quite right. The truth is, these experiences can influence every part of a person’s life—how they think, feel, sleep, connect with others, and even how their body functions.

Many people who carry unresolved emotional pain experience irritability or mood swings that seem out of proportion to what’s happening around them. Anxiety is another common reaction, often felt as persistent worry, tension, or a heightened sense of alertness.

These psychological wounds can also affect focus—difficulty concentrating or feeling mentally foggy is a frequent challenge.

People who’ve lived through distressing events may relive them through flashbacks, nightmares, or vivid, intrusive memories. To cope, many avoid places, people, or situations that stir up painful reminders. Others may dissociate—feeling zoned out, disconnected from their bodies, or losing track of time.

Sleep struggles are also common. Many individuals report difficulty falling or staying asleep, while others are jolted awake by racing thoughts or distressing dreams. Over time, disrupted sleep can make emotional regulation and decision-making even more difficult.

The way deep emotional wounds show up varies widely from person to person. But no matter what it looks like on the outside, the effects are very real and deserve to be acknowledged and addressed.

Who is most at risk for trauma?

No one is immune to the emotional impact of distressing experiences. However, certain people and communities may be more vulnerable due to the environments they live in or the systemic challenges they face.

Marginalized groups—including people of color, LGBTQ+ individuals, refugees, and those living in poverty—often face ongoing challenges within their families and communities rooted in discrimination, oppression, or instability. These hardships are often intensified by limited access to resources and support.

Unfortunately, stigma around mental health continues to be a significant barrier that keeps many people from getting the help they need. The fear of being judged or misunderstood can lead to silence, even when support is desperately needed.

What is trauma-informed care?

This type of therapy centers on building a strong, trusting relationship, creating a sense of emotional and physical safety, and avoiding practices that might resurface painful memories. Therapists move at the client’s pace and customize their approach based on each person’s experiences, needs, and boundaries.

Trauma-informed and trauma-focused approaches are closely connected but serve different purposes. This type of compassion-focused care creates a supportive environment by recognizing how common overwhelming experiences are and how they can impact a person’s mental and emotional well-being. In contrast, targeted therapy takes a deeper approach, helping individuals process specific past events and move toward healing. 

There are several effective therapies that can help individuals process their experiences, develop healthy coping strategies, and move forward with a stronger sense of self.

Cognitive Behavioral Therapy (CBT) is one of the most widely used approaches. It helps individuals identify and reframe negative thought patterns that often stem from psychological injury. By learning new ways to think and respond, people can begin to reduce anxiety, shame, and fear.

Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) combines elements of CBT with trauma-sensitive interventions to help people understand their feelings, change unhelpful thoughts, and feel safer in their daily lives.

Eye Movement Desensitization and Reprocessing (EMDR) is a structured modality that uses guided eye movements or tapping to help the brain process and release painful memories. It’s particularly effective for those with PTSD or distress tied to specific events.

Family therapy can be especially helpful for healing emotional pain that originates in a family setting. It fosters open communication, cultivates empathy, and creates a safe space for healing together.

These therapies—and others like them—can be powerful tools for reclaiming a sense of safety, connection, and emotional balance.
