Does TRE Work? TRE Myths, Facts, and Side Effects

Separating what we know from what gets overstated about neurogenic tremoring

You may have heard big claims about TRE®: "It changed my life overnight" or "I shook out decades of trauma in one session." You may also have heard the opposite: "It's just muscle fatigue" or "Shaking will retraumatize you."

Both extremes miss the mark. TRE (Tension & Trauma Releasing Exercises) is a simple set of exercises, developed by Dr. David Berceli, that invites the body's natural tremor response. Many people find it calming and helpful. The research, though, is still early. This guide walks through seven common myths, what the evidence actually says, and how to start safely. If you are new to the practice, our complete guide to what TRE is is a good place to begin.

What the Research Says So Far

It helps to start with an honest picture of the evidence, because most myths grow out of overstating it in one direction or the other.

• Studies are small and early. Most published TRE research consists of pilot studies, case reports, and small trials. A 2023 scoping review of 18 studies found the existing evidence to be preliminary, with varied methodological quality.
• Some results are encouraging. A pilot study with non-professional caregivers reported improvements in quality-of-life measures after TRE practice (Berceli et al., 2014). An exploratory pilot study with people living with multiple sclerosis found the exercises feasible, with some self-reported improvements that still need testing in larger, controlled studies (Lynning et al., 2021).
• Not every study finds an effect. A randomized controlled trial using similar exercises for restless legs syndrome found no significant difference between a small TRE group and a discussion-group control (Harrison et al., 2018).

The fair summary: TRE is low-cost, generally well tolerated, and promising, but it is not yet a proven treatment for trauma or any medical condition. That is the lens we use for the myths below.

Myth #1: "TRE Is Just Muscle Fatigue"

The misconception: The shaking is simply tired muscles, like the wobble you get at the end of a hard workout.

What we know: The exercises do fatigue certain muscles, and that fatigue helps start the process. But the tremoring people describe in TRE usually looks different from exercise shakes:

• It often begins after the exercises, while lying down and resting.
• It can continue without effort and can be slowed or stopped at will.
• It may move through the body in waves rather than staying in one tired muscle.
• Many people describe it as releasing or calming rather than straining.

Trembling after stress is a normal part of how the body settles. What we can't yet say with confidence is exactly why TRE feels calming for so many people. Early physiological research, including work on heart rate variability, is exploring this, but the mechanism is not settled.

Bottom line: Fatigue is the starting point, not the whole story, and the "why" is still being studied.

Myth #2: "You Have to Shake Hard for It to Work"

The misconception: Big, dramatic shaking means more release. Small movements mean it isn't working.

What we know: There is no evidence that stronger tremors produce better results. In practice, pushing for intensity is one of the most common ways people end up feeling overwhelmed.

• Some people have full-body tremors. Others feel subtle, internal vibration.
• Many people alternate between intensities over time.
• How you feel afterward (settled, rested, more present) matters more than how much you shook.

Bottom line: Gentle, regular practice within your comfort zone is the goal.

Myth #3: "TRE Will Retraumatize You"

The misconception: Tremoring will flood you with memories or feelings you can't handle.

What we know: TRE does not ask you to talk about or relive traumatic events. You stay aware throughout, and you can slow down or stop the tremors at any time by straightening your legs or changing position. Well-trained providers teach this "brake" early. That said, strong emotions or sensations can come up, especially for people with significant trauma histories. That is why pacing matters.

Problems are more likely when people:

• Practice for long stretches too soon
• Push through signals to slow down
• Practice alone during a period of acute distress

Staying within your window of tolerance is the key idea. If you have a complex trauma history, a dissociative condition, or are in crisis, learn TRE with a certified provider, ideally alongside a therapist.

Possible side effects: People commonly report short-term effects such as tiredness, mild muscle soreness, emotional release (like tears or laughter), or vivid dreams after early sessions. These usually settle as practice becomes gentler and more familiar. If effects feel intense or last, shorten your sessions and talk with your provider.

Bottom line: TRE is generally well tolerated when paced carefully. It isn't risk-free for everyone, which is why guidance matters.

Myth #4: "TRE Is a Quick Fix"

The misconception: One or two sessions will resolve years of stress or trauma.

What we know: Some people feel calmer right after a session. Longer-term changes, when they happen, tend to build gradually with regular practice. TRE is best thought of as a self-regulation tool, not a cure.

What TRE may help with: feeling calmer after stressful days, easing physical tension, sleeping better, and feeling more at home in your body. These are commonly reported experiences, not guaranteed outcomes.

What TRE can't do: replace medical care, psychotherapy, or crisis support; resolve complex trauma on its own; or change difficult life circumstances.

Bottom line: Think in months of steady practice, not single breakthrough sessions.

Myth #5: "TRE Works the Same Way for Everyone"

The misconception: Everyone will have the same kind of tremors, emotions, and timeline.

What we know: Experiences vary widely. People differ in where and how they tremor, whether emotions come up, how often they benefit from practicing, and what changes they notice. Stress levels, health conditions, medications, injuries, and support systems all play a role.

Bottom line: Compare your practice to your own baseline, not to someone else's story.

Myth #6: "TRE Is Better Than Other Trauma Therapies"

The misconception: Because TRE works with the body, it is superior to talk therapy or other approaches.

What we know: TRE has far less research behind it than established trauma treatments such as trauma-focused cognitive behavioral therapy or EMDR. It can be a helpful complement, especially for people who want a body-based, non-verbal tool, but it does not replace relational therapy.

At Red Beard Somatic Therapy, TRE often sits alongside approaches like Somatic Experiencing and Internal Family Systems (IFS), chosen to fit the person rather than the other way around.

Bottom line: TRE is one useful tool among many.

Myth #7: "If You're Not Healing Fast, You're Doing It Wrong"

The misconception: Slow or subtle progress means you're failing at TRE.

What we know: Slower progress is common, and often safer. Signs that practice is helping can be quiet: recovering more quickly after stress, sleeping a little better, noticing tension sooner.

Check in with a professional if you:

• Consistently feel worse after sessions
• Notice increasing anxiety, insomnia, or overwhelm
• See no change after a few months of regular practice

Bottom line: Steady, small shifts count.

How to Start TRE Safely

• Learn from a certified TRE provider for your first sessions, so you learn how to pace and pause.
• Start short. A few minutes of tremoring is enough at first.
• Check with your doctor if you are pregnant, have a recent injury or surgery, a seizure disorder, or another medical condition that affects exercise.
• Pair it with support if you are working through significant trauma.
