How does Somatic Experiencing® (SE™) work?

How wild animals release shock

Dr. Peter Levine began studying stress in the nervous systems of animals after realizing that, despite constantly facing threats, they do not exhibit trauma symptoms. He discovered that trauma is linked to the “freeze response”, the third survival reaction to life-threatening danger. When fight or flight is not an option, we freeze, just as animals do, playing dead as a last-ditch attempt to escape a predator. Once the danger passes, the massive energy prepared for fight or flight must be discharged through trembling. If this process remains incomplete, the trapped energy lingers in the body, keeping it in a state of perceived threat. The Somatic Experiencing® (SE™) method works to release this energy and switch off the “alarm system” that causes severe dysregulation and dissociation.

Renegotiation
According to SE™, the traumatic event itself is not what causes trauma. Instead, trauma arises from an overwhelming response to a perceived life threat, which disrupts the nervous system’s balance. The goal is to access the body’s memory of the event, rather than the verbal narrative. This means that clients do not need to discuss what happened unless they choose to.

Titration 
SE™ introduces the principle of titration, which involves slowly releasing stored energy in small, manageable amounts. The process follows cycles in which natural internal sensations, such as contraction/expansion, pleasure/pain, warmth/cold, are observed only at a level the client can comfortably handle. This rhythmic, gradual approach builds resilience, enhancing the ability to manage stress and stay present in the moment.

Pendulation
Pendulation, a term coined by Dr. Levine, describes the natural oscillation between opposing states, such as contraction and expansion. SE™ harnesses this principle to restore a sense of flow in the body. The client shifts their attention back and forth between areas of pain and areas of well-being until the stored tension is released.

Bottom-up processing 
Like other somatic approaches, SE™ applies a “body-first” framework, focusing on the physiological symptoms of trauma rather than cognitive processing. The therapy does not involve reliving memories or altering thoughts. Instead, it helps clients observe the sensations behind emotions and uncover behavioral patterns linked to those feelings.
