Maybe you've seen the videos: someone lying on a mat, knees bent, legs trembling on their own, and a caption promising that the shaking releases trauma stored in the body. Part of you is curious. Part of you is hopeful. And part of you is wondering whether it is actually a good idea to try something like that alone in your living room.
Here is the honest answer. You can do trauma release exercises at home safely if you go slowly, keep sessions short, stay in charge of when the shaking stops, and skip home practice if you have PTSD, frequent dissociation or certain medical conditions. The research is still early. TRE can feel calming for many people, but it is not a proven treatment for trauma.
This guide explains what TRE is, what the evidence does and doesn't show, who should wait or get guidance first, and a gentle step-by-step way to try it, including how to stop and what to do if it stirs up more than you expected.
TRE stands for Tension and Trauma Releasing Exercises. It was developed by the therapist David Berceli, and it consists of a short sequence of simple stretches that gently tire the leg and hip muscles. Afterward, you lie on your back in a particular position and allow a mild, involuntary tremor to start in your legs. Proponents call this a "neurogenic tremor," meaning a shaking that comes from the nervous system rather than from you deliberately moving.
Shaking after stress is a normal human experience. People often tremble after a near miss in traffic, after giving a speech, or after a heated argument, as adrenaline clears from the body. We look at that everyday version in our article on why you shake when you're angry. TRE is built on the idea that deliberately inviting a gentle tremor, in a safe setting, can help the body let go of tension.
What TRE is not is a way to literally shake trauma out of your muscles. The idea that traumatic memories are "stored" in specific muscles and released through movement is a popular metaphor online, but it is not an established scientific finding. A more modest and plausible explanation is that tiring the muscles, letting them release, and spending quiet time paying attention to your body can be deeply relaxing, somewhat like progressive muscle relaxation. That is a real benefit. It just isn't the same as treating trauma.
TRE is widely taught around the world, but the research behind it is thin. A 2024 peer-reviewed trial protocol in BMC Complementary Medicine and Therapies states plainly that the method lacks sufficient evidence-based research, despite its popularity. The studies it cites are small: one early trial with college students that reported lower anxiety, and a small pilot study in people with multiple sclerosis, in which nine weeks of daily practice was linked to milder symptoms.
Small, early studies like these are worth taking seriously as a starting point, but they can't tell us how well TRE works, who it helps most, or whether it helps with trauma specifically. Larger, well-designed trials are only now being run.
For comparison, the treatments with strong evidence for post-traumatic stress disorder (PTSD) are talking therapies that work directly with traumatic memories. The NHS lists trauma-focused cognitive behavioral therapy and EMDR (eye movement desensitization and reprocessing) as the main therapies, sometimes alongside medication. If trauma is significantly affecting your life, TRE belongs alongside those options at most, never in place of them.
For many people, TRE is a gentle, low-risk practice. But anything that turns your attention inward and stirs up strong body sensations can also stir up emotions, memories or a sense of disconnection. That is why doing trauma release exercises at home safely comes down to three things: who, how much and when.
Please don't practice alone at home, and instead look for a trained provider or trauma-informed therapist, if:
Check with your doctor first if you:
If you take medication for your mental health, TRE is not a reason to change it. Any changes to medication should only happen with your prescriber.
If you want to do trauma release exercises at home safely, these principles matter more than getting the exercises exactly right. Read them first.
Set up somewhere warm and private, with a yoga mat or rug, loose clothing, and a glass of water nearby. It helps to tell someone you trust that you're trying it, especially the first time.
The sequence below is a simplified, gentle version of the kind of movements TRE uses. It is not the official full protocol, which is best learned from a certified provider. Move within a comfortable range, skip anything that hurts, and use a wall or chair for balance whenever you like.
These movements mildly tire the muscles of the legs and hips, which makes it easier for a tremor to appear later. You should feel effort, not pain.
At first, two or three short sessions a week is plenty. See how you feel over the following day before deciding to do more.
Emotion during TRE is not automatically a problem. Some people feel a wave of sadness, a few tears, or an unexpected laugh, and then feel lighter. The line to watch is between feeling something and being overwhelmed by it.
Stop the session if you notice:
When you stop, focus on bringing yourself fully into the present. Straighten your legs, open your eyes wide, and sit up. Press your feet into the floor. Name five things you can see and three things you can hear. Hold something cold, or run cool water over your hands. If you've been through something like this before, our explanation of somatic flashbacks, when the body remembers first, and our guide to grounding yourself during emotional flashbacks may help you make sense of it.
If these reactions happen more than once, please stop practicing on your own. It doesn't mean you did anything wrong. It means your system needs a slower pace and a skilled person alongside you.
Common after-effects are tiredness, a heavy calm, mild muscle soreness in the thighs (much like after a workout), or feeling a little emotional for a while. Many people also report sleeping more deeply, though that is an individual experience rather than a research finding.
Less welcome after-effects include feeling on edge, irritable or restless for several hours, or trouble sleeping that night. If that happens, it usually means the dose was too big. Make the next session shorter, keep the tremor gentler, or take a longer break between sessions.
If TRE feels like too much right now, or you fall into one of the groups above, there are quieter ways to build a sense of safety in your body first:
These can be a good foundation, and some people go on to try TRE later, when they feel more settled.
This article is general information, not therapy or medical advice. If painful experiences from your past are affecting your sleep, relationships, work or sense of safety, please talk to your doctor or a trauma-informed therapist. Evidence-based options include trauma-focused CBT and EMDR. Body-based therapies such as somatic experiencing and sensorimotor psychotherapy are also available, although their research base is still developing. If you'd like to learn TRE itself, a few sessions with a certified provider can make it much easier to practice safely at home afterward. Look for someone who can tell you about their training in mental health and trauma, especially if you have a trauma history.
If you are in crisis, feel unsafe, or are thinking about harming yourself, please reach out right now. In the US, call or text 988. In the UK and Ireland, call Samaritans on 116 123. In Canada, call or text 988. In Australia, call Lifeline on 13 11 14.
Yes, some people cry, sigh deeply, yawn or even laugh during or after a session, and that can feel like a relief. What matters is whether you stay present. Tears while you still feel connected to the room are usually fine. If crying turns into panic, numbness or a sense of reliving something, stop the session and use grounding to bring yourself back.
There is no research-based answer yet. A cautious approach is two or three short sessions a week at first, with five to ten minutes of tremoring each time. Notice how you feel over the next day before increasing anything. If you feel wired, tearful or unsettled afterward, reduce the length or frequency.
It can for some people, particularly those with PTSD or a tendency to dissociate, if they go too fast or too long. That is why short sessions, a clear way to stop, and professional guidance for anyone with significant trauma history are so important. If your symptoms get worse after practicing, stop and speak to a professional.
That claim goes further than the evidence. The idea of trauma being stored in muscles is a popular metaphor, not an established finding, and research on TRE so far consists of small, early studies. It may help some people relax and feel more at ease in their bodies, which is valuable, but it is not a replacement for proven trauma therapies.
A firm surface such as a mat on the floor works better, because a soft mattress makes it harder to control the position of your knees and hips. Some people also find a session leaves them feeling alert rather than sleepy, so it is worth seeing how you respond before making it part of a bedtime routine.
That is common and nothing to worry about. Some people need several sessions before a tremor appears, and some never experience much of one. Don't force it by straining. The warm-up, the quiet time lying down and the slow breathing can still be relaxing in their own right.
If you want to try trauma release exercises at home safely, the most important ingredients are not the stretches themselves. They are pace, choice and a clear way back to the present. TRE may help you feel calmer and more at home in your body, but the evidence is still early, and it works best as one gentle tool rather than a cure.
If you decide to try it, make your first session a short one: the warm-up, five minutes lying in the butterfly position, and then practice stopping by straightening your legs. Notice how you feel the next day. That small, careful experiment will tell you more than any video can.
