What is Prolonged Exposure Therapy?
Prolonged Exposure (PE) therapy is an evidence-based trauma therapy that helps people process and recover from traumatic experiences. PE is commonly used to treat PTSD. It can help people who continue to feel emotionally overwhelmed by painful life experiences.
PE is based on the understanding that many people experience distressing symptoms after a traumatic event. These symptoms may include vivid memories, nightmares, emotional numbness, anxiety, and/or intense emotional and physical reactions to reminders of the trauma. For many people, these symptoms gradually improve over time. When PTSD develops, avoidance can interfere with the brain’s natural recovery process, keeping symptoms going long after the danger has passed.
The name “Prolonged Exposure” can sometimes sound intimidating. However, PE is one of the most researched and effective treatments for PTSD. Many people find that the hardest part of living with PTSD is that traumatic memories seem to appear unexpectedly, through nightmares, intrusive memories, or intense emotional reactions to reminders of the trauma. When the memories come up out of the blue, it can feel like the wind has been knocked out of you. In response, people naturally try to avoid situations, places, thoughts, feelings, or memories that trigger distress. As humans, it is natural to want to avoid pain. However, while avoidance may provide temporary relief, it often strengthens PTSD symptoms over time and prevents recovery. I often think about avoidance as short-term gain (the immediate distress decreases) but long-term pain (the next time this situation comes up the harder it is to not avoid it). For example, if you have a fear of public speaking and your job requires you to give a speech. If you feel panicked and fake sick on the day of the scheduled talk, in the short-run your anxiety decreases as you don’t have to give the talk. However, you lose the opportunity to create new learning that giving the talk was not as bad as you thought it would be and you got through it. The next time you have to give a talk, the anxiety is often even stronger because you never had the opportunity to learn that you could handle it. If you had to give a talk every day despite your anxiety, over time you would learn that you can tolerate the anxiety and still be effective. As that learning grows, the anxiety often begins to decrease. The same principle holds true with trauma memories.
The more we avoid them, the more we prevent new learning and strengthen the hold those memories have over us.
How Does Prolonged Exposure Therapy Work?
PE helps people gradually and systematically approach trauma-related memories, emotions, and situations that they have been avoiding. By doing so, the brain has an opportunity to learn that these memories, while painful, are not dangerous. We also learn that safe reminders of the event are not dangerous and can be approached.
What is Imaginal Exposure in Prolonged Exposure Therapy?
A central part of PE is called imaginal exposure. During imaginal exposure, you revisit and describe the traumatic memory in a safe and supportive therapeutic environment. Many people also discover that they can tolerate the emotions associated with the memory more effectively than they initially believed. The memory becomes something that happened in the past rather than something that continues to feel like a present threat.
What is In-Vivo Exposure in Prolonged Exposure Therapy?
Another important component of PE is in vivo (or real-life) exposure, which involves gradually approaching safe situations, places, or activities that have been avoided because they trigger trauma-related fear or distress. Here’s a funny example to understand what happens when we experience a trauma. Let’s say a bear comes into my office in the middle of the city. Without thinking, I will react. I might freeze. I might fight. I might flee. As humans, we are wired to survive. So, in this silly example, I might freeze and the bear leaves. The threat is gone and my body will gradually return to a normal state. But, let’s say my phone rang before the bear came into the office. Without thinking about it, my body and mind would pair the phone with the threat of the bear—because we are primed to survive. Then, when the bear is gone and the phone rings, my body would react as if the bear was there and I would be in the fight-flight-freeze response. Let’s say, I start to avoid phones because I don’t want to feel this intense feeling. Think about how small life would become if I avoided all phones, office phones, cell phones, and video calls. This is what happens during a traumatic event. Safe reminders in the environment get paired with the trauma and if we avoid these safe reminders we prevent new corrective learning. In-vivo exposure is a technique to help you approach safe reminders that have been paired with your trauma so that you can do the things you want to do rather than avoiding out of fear. Over time, people often regain confidence and begin participating more fully in the activities and relationships that matter to them.
As avoidance decreases, many individuals develop a more balanced understanding of the trauma and emotionally process the event. The goal is not to forget what happened, but to reduce the power the trauma has over your daily life.
Importantly, PE focuses on approaching situations that are objectively safe but have become associated with danger because of the trauma.
What Does Avoidance Look Like?
Many people struggling with PTSD are surprised by how much avoidance has become part of their daily lives. Avoidance can be obvious, but it can also be subtle.
Examples may include:
Avoiding crowds due to fears about safety
Avoiding close relationships due to fears of loss or vulnerability
Avoiding men if the perpetrator was a man
Avoiding supermarkets, public places, or driving
Avoiding certain smells, sounds, or locations associated with the trauma
Avoiding places connected to the traumatic event
Keeping excessively busy to avoid thinking about the trauma
Avoiding emotions such as sadness, fear, guilt, or anger
Avoiding conversations about what happened
Using alcohol, substances, work, or excessive screen time to escape distressing thoughts or feelings
In PE, you learn to identify when avoidance is keeping you from living the life you want to live. Through gradual practice, you learn to approach rather than avoid difficult experiences, helping you regain a sense of freedom and choice.
Is Prolonged Exposure Therapy Re-Traumatizing?
Prolonged Exposure is a collaborative form of trauma therapy that follows a structured approach while remaining tailored to your individual needs and goals.
Treatment may include:
Learning about trauma symptoms and how they affect daily life
Understanding the role avoidance plays in maintaining PTSD symptoms
Identifying situations, places, thoughts, and feelings that have been avoided
Participating in imaginal exposure exercises during sessions and listening to recordings of those exercises between sessions
Practicing in vivo exposure between sessions
Developing skills to approach difficult situations with greater confidence
Building confidence in your ability to approach difficult memories, emotions, and situations
Reconnecting with activities, relationships, and goals that matter to you
Who Can Benefit from Prolonged Exposure Therapy for PTSD?
Prolonged Exposure may be helpful for adults who have experienced:
Childhood trauma
Sexual assault
Medical trauma
Military trauma
Relationship violence
Accidents or frightening events
Sudden loss or other overwhelming life experiences that cause PTSD symptoms
People often seek PE when trauma continues to affect relationships, self-esteem, work, or their sense of safety in the world.
Common experiences may include:
Intrusive memories or nightmares
Hypervigilance or feeling constantly "on edge"
Avoidance of trauma reminders
Difficulty trusting others
Anxiety in situations that feel unsafe
Emotional numbness or disconnection
Distressing memories from childhood or relationships
Is Prolonged Exposure Therapy Effective for PTSD?
PE is recognized as an effective treatment for PTSD by organizations including the American Psychological Association, the World Health Organization, and the U.S. Department of Veterans Affairs. Research has consistently shown that PE can significantly reduce trauma-related symptoms and improve overall quality of life.
PE does not erase traumatic memories. Instead, successful treatment helps memories feel less overwhelming so that decisions can be made from a place of choice rather than fear, shame, or avoidance.
Treatment length varies depending on your experiences, goals, and current stressors. PE is often completed in approximately 8–15 sessions, although treatment may be shorter or longer depending on individual needs and progress. Sessions are often 90 minutes in length.
Is PE Right for Me?
PE may be a good fit if:
You experience PTSD symptoms related to a traumatic event
You find yourself avoiding reminders of the trauma
Traumatic memories continue to interfere with daily life
You want a structured, evidence-based approach to treatment
You are ready to gradually work toward confronting rather than avoiding trauma-related fears
During an initial consultation, we can discuss your experiences, goals, and concerns to determine whether PE is the right treatment approach for you.
Taking the First Step
Beginning trauma therapy can feel intimidating, especially if you have spent a long time coping on your own. Many clients come to PE worried that talking about the trauma will make things worse. In my experience, people are often surprised to discover that approaching difficult memories in a structured and supportive way helps them feel more in control and less stuck.
Healing does not mean forgetting what happened. Healing means that the past no longer has to control the present.
If trauma continues to affect your relationships, confidence, or daily life, PE may be able to help. Contact me to schedule a consultation and learn whether Prolonged Exposure Therapy is a good fit for your goals.
Frequently Asked Questions About Prolonged Exposure Therapy
Will Prolonged Exposure Therapy make me relive my trauma?
This is one of the most common concerns people have about PE. While PE involves talking about and revisiting traumatic memories, the goal is not to force you to relive the trauma. Instead, PE helps you approach memories in a safe, structured, and intentional way so that they become less distressing over time. Many people find that they feel more in control of their memories as treatment progresses.
Is Prolonged Exposure Therapy re-traumatizing?
Research has consistently shown that PE is a safe and effective treatment for PTSD. Although discussing traumatic experiences can feel emotionally challenging, PE is conducted gradually and collaboratively. Most people find that avoiding trauma memories is more exhausting and disruptive than learning how to approach them in a structured way.
What if I am not ready to talk about my trauma?
Many people feel unsure about discussing their trauma when they first seek therapy. It is normal to feel nervous. In PE, we spend time helping you understand PTSD, learning about avoidance, and preparing for exposure exercises before diving into the trauma memory. Treatment moves at a pace that is challenging but manageable.
How long does Prolonged Exposure Therapy take?
PE is often completed in approximately 8–15 sessions, although treatment length varies based on individual needs, treatment goals, and the complexity of the trauma history. Sessions are often 90 minutes long to allow enough time for exposure exercises and processing.
What happens during imaginal exposure?
During imaginal exposure, you revisit and describe the traumatic memory in detail during a therapy session. Together, we explore the memory from beginning to end rather than focusing only on the most distressing moments. Many people find that repeated practice helps the memory feel less overwhelming and easier to manage.
What happens between sessions?
Between sessions, clients listen to recordings of imaginal exposure exercises and practice approaching safe situations, places, or activities they have been avoiding. These exercises help strengthen new learning and support progress outside of therapy sessions.
Will I have homework in PE?
Yes. PE includes practice between sessions because recovery happens both inside and outside of therapy. I think about it like training for a marathon. Running one day a week won’t be enough. The practice assignments allow for quicker recovery and healing. Homework often involves listening to session recordings and completing in vivo exposure exercises that we plan together. These activities are tailored to your goals and current level of readiness.
How is Prolonged Exposure Therapy different from simply talking about the trauma?
Many people have talked about their trauma with friends, family members, or previous therapists. PE differs because it uses a structured and evidence-based approach designed specifically to reduce PTSD symptoms. The therapy focuses on helping you approach trauma memories and avoided situations in ways that promote emotional processing and new learning.
Can Prolonged Exposure Therapy help with childhood trauma?
Yes. PE can be effective for adults who experienced childhood trauma and continue to experience PTSD symptoms related to those experiences. Treatment focuses on the impact the trauma is having on your life today rather than how long ago it occurred.
What if I have had more than one significant trauma, can PE still help me?
Yes. Many people suffering from PTSD have experienced multiple traumatic events. We would work together to determine which event to focus on first. Usually, we recommend focusing first on the worst trauma. Often, when we process the trauma that is causing the greatest distress, people notice improvement across multiple trauma-related memories and triggers. If significant symptoms remain related to another trauma, we can then address that memory as well.
How do I know if PE is right for me?
PE may be a good fit if PTSD symptoms are interfering with your life and avoidance has become a common way of coping. During an initial consultation, we can discuss your symptoms, treatment goals, and concerns to determine whether PE or another evidence-based trauma therapy would be the best fit for your needs.
