SE 101

Somatic Experiencing (SE™) aims to resolve symptoms of stress, shock, and trauma that accumulate in our bodies and nervous systems. Trauma, from an SE lens, is focused on how it shows up in the nervous system and how that dysregulation impacts life. When we are stuck in patterns of fight, flight, or freeze, SE helps us release, recover, and become more resilient. It is a body-oriented therapeutic model applied in multiple professions and professional settings—psychotherapy, medicine, coaching, teaching, and physical therapy—for healing trauma and other stress disorders from a nervous system lens within a practitioner’s scope of practice. It is based on a multidisciplinary intersection of physiology, psychology, ethology, biology, neuroscience, indigenous healing practices, and medical biophysics and has been clinically applied for more than four decades. It is the life’s work of Dr. Peter A. Levine.

The SE approach releases traumatic shock, which is key to transforming patterns that get stuck and impact people’s daily life. It can be used to support the resolution of PTSD and developmental attachment trauma. It offers a framework to assess where a person is “stuck” in the fight, flight or freeze responses and provides clinical tools to resolve these fixated physiological states. SE provides effective skills appropriate to a variety of healing professions including mental health, medicine, physical and occupational therapies, bodywork, addiction treatment, first response, education, and others. These SE skills support healing professionals holistically apply their work in supporting individuals and groups.


Trauma may begin as acute stress from a perceived life-threat or as the end product of cumulative stress. Both types of stress can impair, sometimes seriously, a person’s ability to function with resilience and ease. Trauma may result from a wide variety of stressors such as accidents, invasive medical procedures, sexual or physical assault, emotional abuse, neglect, war, natural disasters, loss, birth trauma, epigenetics, systems, or the corrosive stressors of ongoing fear and conflict.


The Somatic Experiencing approach facilitates the completion of self- protective motor responses and the release of thwarted survival energy bound in the body, thus addressing the root cause of trauma symptoms. This is approached by gently guiding clients to develop increasing tolerance for difficult bodily sensations and suppressed emotions and working to complete defensive responses previously thwarted from bringing resolution to the nervous system and, therefore, to the individual.

Dr. Levine was inspired to study stress on the animal nervous system when he realized that animals are constantly under threat of death yet show no symptoms of trauma stuck in their systems. What he discovered was that trauma has to do with the third survival response to a perceived life threat, which is freeze. When fight and flight are not options, we freeze and immobilize, like “playing dead.” This makes us less of a target. However, this reaction is designed to be time-sensitive, in other words, it needs to run its course, and the massive energy that was prepared for fight or flight gets discharged, through shakes and trembling. If the immobility phase isn’t complete, that charge stays trapped, and, from the body’s perspective, it is still under threat. The Somatic Experiencing method works to release this stored energy and turn off this threat alarm that causes dysregulation and dissociation. SE helps people understand this body response to trauma and work through a “body first” approach to healing. Within their scope of practice, SE Practitioners work with these responses in a way that supports their ongoing work with clients.

What our practitioners are saying

“SE provides the basic natural healing and core nervous system skills for all the work I do, and its natural mindfulness as well. It helps clients attune to what's happening in their bodies, slow down and pause fast energies, wake up and balance sympathetic and parasympathetic nervous systems. Learning to consciously titrate gives clients a boost in self-awareness, and confidence in their capacity to change and heal. These basic and natural SE practices and tools help clients re-enter a traumatized or dissociated body slowly, at their own pace, and gradually (for some) more safely.”

In this 5-minute video, Dr. Peter Levine, founder of Somatic Experiencing, discusses how he came to create his powerful approach to trauma.

This video tells the compassionate story of the healing process of Ray, a Marine who had been injured by two improvised explosive devices (IEDs) and diagnosed with both severe PTSD and Traumatic Brain Injury (TBI). Dr. Levine demonstrates the power of SE as a tool to heal the wounds of war.

Dr. Peter Levine uses his famous “Slinky” presentation to demonstrate the effects of trauma on the nervous system, and his philosophy of treating trauma, which involves slowly releasing (or titrating) this compressed fight-or-flight energy a bit at time to give the individual the ability to reintegrate it back into the nervous system.

Dr. Peter A. Levine received his Ph.D. in medical biophysics from the University of California in Berkeley and also holds a doctorate in psychology from International University. He has worked in the field of stress and trauma for over 40 years and is the developer of the Somatic Experiencing® method. Peter’s original contribution to the field of Body-Psychotherapy was honored in 2010 when he received the Lifetime Achievement award from the United States Association for Body Psychotherapy (USABP). That same year he also received the honorary Reis Davis Chair in Child Psychiatry for his innovative contribution to therapy for children and adolescents.

Waking the Tiger, Tiger


The image of the tiger was invoked by Dr. Peter A. Levine during his first session with “Nancy,” who suffered from an array of symptoms, in an event that would define and shape his career. Without warning, Nancy suddenly froze, her pulse skyrocketing as she began reliving the moments before a traumatic childhood surgery, including being bound and anesthetized with ether. “I’m going to die! Please don’t let me die!” she repeated, helplessly. Amidst this chaos, Dr. Levine was compelled, by a seemingly prescient vision of a charging tiger, to say: “Nancy, you're being chased by a tiger. Run! Run for the nearest tree!” It was at this moment, as Nancy began kicking her feet, that Dr. Levine first witnessed the human animal’s innate ability to heal from shock and terror by completing the instinctual, self-protective act that had been overwhelmed and frozen into her body’s nervous system, over 20 years earlier. On repeated follow up, this single session had a dramatic impact on Nancy's life, including the dissolution of her agoraphobia, cessation of her migraines, and a renewed, sustained vigor in living. The tiger has become a symbol of our aliveness, our innate nature.
