Somatic release can be a natural part of the healing process, helping the nervous system complete unresolved protective responses and release stored tension and energy. It can express itself in many ways, including tremors, spontaneous movement, sound, breath, or emotional expression. Tremoring is one form of somatic release that may appear during recovery from chronic illness, chronic pain, or trauma as the body begins to discharge long-held tension.
For some, this shows up as shaking, quivering, or body movements that arise naturally during relaxation, trauma processing, or any form of nervous system regulation.
While it can feel strange or even frightening, these tremors are the body’s natural way of completing unfinished protective responses and unwinding long-held muscle tension. They often appear as the nervous system gains more safety and capacity. This allows one to become more embodied and able to feel sensations, emotions, survival energy, and incomplete movement impulses the body has been holding.
This process is seen in animals too – after a threat, they instinctively shake to release the survival energy of the moment. Humans living in modern societies have largely forgotten or unconsciously inhibited this innate release mechanism. But it can naturally re-emerge as a felt sense of safety in the body is restored, together with an understanding that this is a safe and natural process.

Tremors are thought to arise from incomplete protective responses – instinctive movements the body prepared during threat or danger but could not complete due to freezing or inhibition.
Once a sufficient sense of safety is restored, these stored impulses can release spontaneously through tremoring or instinctive movements.
The mechanism is similar to what’s observed in animals after danger has passed (see the polar bear video below).
In addition to releasing acute threat responses, people with chronic illness or chronic pain may also experience tremoring as long-held muscle tension begins to release, even without a history of acute trauma. The exact mechanism isn’t fully understood, but tremoring appears to be one way the body discharges stored tension and returns to a more relaxed state.
Tremors often occur during rest, meditation, or relaxation – moments when the body finally feels safe to release. This can also include safe connection with others.
Allowing gentle, spontaneous tremors can support nervous system regulation and relaxation. It is important to stay within a sense of safety (often referred to as the “window of tolerance”) and to avoid forcing or consciously controlling the process.

Tremors can range from subtle vibrations to large, coordinated movements.
They often occur during rest, meditation, or relaxation – moments when the body finally feels safe to release.
The experience can bring up emotions such as tears, laughter, or fear; these are often part of the same release process.
It is generally advised to let the process happen without resistance, staying curious and grounded.
If the experience feels overwhelming, a somatic practitioner can help guide and contain it safely.

For most people, tremoring remains relatively simple - gentle shaking, vibrations, or small movements. However, as nervous system capacity increases over time, some people experience more complex somatic releases. These fuller expressions are less common and often occur in later stages of healing, sometimes with practitioner support. They can include:
Complex defensive movement sequences, sometimes accompanied by emotion, such as:
Pushing, kicking, or other protective movements, possibly with vocalizations or expression of healthy aggression
Running or lunging motions
Curling into protective postures, sometimes with emotional expression like grief or anger
Alongside these somatic releases, some people also notice an emergence of:
Bodily sensations, which can feel like new symptoms or the temporary return of old symptoms
Emotional experiences, including grief, rage, fear, healthy aggression, and other stored feelings
Conscious memories surfacing that were previously inaccessible
These experiences often reflect the nervous system’s growing capacity to feel and process what was previously held outside of awareness. This is a normal part of healing, and releasing these held responses can help a person feel calmer and more grounded over time.
Some people move through this process quickly, leading to a felt sense of regulation and calm. For others, it unfolds more gradually and in waves – periods of increased capacity followed by the emergence of additional material to be felt and expressed.
We can't know in advance how much material will surface, as it doesn't necessarily follow what someone knows of their trauma history. The best approach is to remain open and present to whatever arises, without assumptions or expectations.

There’s a high degree of variability in people’s experiences of tremors. They can range from subtle vibrations to large, coordinated movements, lasting from seconds to minutes.
Many people who experience spontaneous tremoring during healing also notice long-standing muscle tension that hasn’t responded well to massage, stretching, or physical therapy. In these cases, the tension is often protective rather than structural, and the body may not yet feel safe enough to relax or perform on demand. As tremoring allows stored defensive energy to release, muscles may gradually soften and regain mobility and strength.
Some people notice temporary, localized physical sensations following tremoring. This can include itching, skin reactions, soreness, or tenderness in the areas that were involved. These responses are often reported in regions that have held long-standing tension.
While the exact mechanism isn’t fully understood, these sensations may reflect areas of the body regaining sensation and circulation after being held in constriction. They are typically transient and ease as the body adjusts.
It’s important to note that not everyone needs to tremor as part of healing. For some, muscle tension softens naturally as the nervous system gains safety. For others, tremoring or spontaneous movement is needed to allow unfinished defensive responses to complete before relaxation becomes possible. Both patterns are normal.

Consider working with a somatic practitioner if:
Tremoring or spontaneous movements feel overwhelming or difficult to settle afterward
You’re experiencing flashbacks or dissociation
You have a complex trauma history
You’re unsure whether what you’re experiencing feels helpful or destabilizing

Somatic Experiencing – a body-based therapy that helps the nervous system complete unfinished survival responses and release stored tension.
TRE (Trauma Release Exercises)* – a simple series of movements designed to safely trigger the body’s natural tremor mechanism.
Continuum Movement – combines breath, sound, and gentle movement to invite awareness and flow into areas of physical contraction.
*Some people explore TRE (Tension & Trauma Releasing Exercises) as a structured way to initiate tremoring. For others, tremors emerge spontaneously as the nervous system gains safety and capacity. Timing and readiness are important — TRE is generally most helpful when the nervous system already has enough capacity to release stored tension. For some, it can serve as an initial way of familiarizing the body with tremoring as a release mechanism.

For context, some tremors may be linked to medical conditions (i.e. neurological or autoimmune conditions) and are sometimes labeled in clinical settings as Functional Tremor, which falls under the Functional Neurological Disorder (FND) spectrum. Some movements that resemble Functional Tremors may actually be part of somatic release processes.
Functional epilepsy (also known as PNES or dissociative seizures) is a separate condition within the FND spectrum and is distinct from functional or somatic tremors. PNES involves seizure-like episodes and changes in consciousness.
This page focuses specifically on somatic tremors and spontaneous movements that arise during recovery and nervous system self-regulation. Any seizure-like episodes, loss of consciousness, sudden collapses, or concerns about neurological symptoms should be evaluated by a qualified healthcare professional.
