"Somatic Experiencing® (SE™) was developed by Peter A. Levine, PhD to address the effects of trauma. Levine developed this approach after observing that prey animals, whose lives are routinely threatened in the wild, are able to recover readily by physically releasing the energy they accumulate during stressful events. Humans, on the other hand, often override these natural ways of regulating the nervous system with feelings of shame and pervasive thoughts, judgments, and fears. Somatic Experiencing aims to help people move past the place where they might be “stuck” in processing a traumatic event.
The autonomic nervous system which includes the sympathetic nervous system (SNS), the parasympathetic nervous system (PSNS), and the enteric nervous system (ENS), is triggered into action when we’re faced with adversity and it governs the fight, flight, or freeze instinct. Although designed to be self-regulating, the ANS can become dysregulated, particularly when full expression of one’s response to trauma is repressed. As a result, the body continues to respond as if it is under threat. Somatic experiencing contends that negative symptoms of trauma—such as anxiety, hypervigilance, aggression, and shame—result from denying the body the opportunity to fully process the traumatic event.
Though many people who experience traumatic events recover completely, for those who do not, unresolved trauma can lead to larger mental and physical health concerns, such as post traumatic stress disorder sleep problems, mood swings, or immune system problems. Somatic Experiencing aims to restore the body’s ability to self-regulate in order to achieve balance and integrity.
Somatic Experiencing sessions involve the introduction of small amounts of traumatic material and the observation of a client’s physical responses to that material, such as shallow breathing or a shift in posture. The therapist will frequently check in with the client to assess and record somatic sensations that may be imperceptible to the practitioner, such as feelings of heaviness, tightness, or dizziness. Practitioners proceed carefully and cautiously to avoid retraumatizing or triggering the client, and they help people to develop and employ self-regulating strategies. A key component to enhancing one’s ability to self-regulate is the practice of alternating, or “pendulating,” between the sensations associated with trauma and those that are a source of strength and comfort.
The SE practitioner will help the client find places of safety, whether that be a place in the body that is not activated by the trauma, or a physical place to retreat to in one’s mind. Experiencing the sensations related to the traumatic event in a safe way allows a person to fully process the trauma. Clients also achieve heightened awareness of their physical responses to stress and this skill can serve them in everyday life."
