Key takeaways
- A 2023 review of 1,039 trials found that physical activity eased anxiety, depression and distress by a medium amount compared with usual care, with bigger gains from harder sessions3.
- In an Army-funded trial of veterans with PTSD, the shaking exercises known as TRE did no better on PTSD symptoms than the same routine without the shaking1.
- Somatic Experiencing, a body-focused trauma therapy, showed large effects in one 63-person trial, but we found no trials of social-media “somatic workouts”2910.
- In a review of 23 studies, moderate exercise didn’t harm sleep even 30 minutes before bed, but in 2025 wearable data, workouts ending within four hours of bedtime, especially hard ones, went with worse sleep1213.
- Exercise can be part of anxiety care but doesn’t replace it, and anyone in crisis can call or text 988.
Lie on your back, bend your knees and bring the soles of your feet together. Then let your knees fall open and wait. After a set of leg-tiring warm-up moves, your legs, pelvis and lower back are meant to start trembling1.
That trembling is the core of tension and trauma releasing exercises, or TRE, a routine developed by David Berceli1. Body-focused “somatic” routines have found big online audiences, too. One TikTok teacher, Liz Tenuto, who calls herself “The Workout Witch,” had 2.2 million followers in 20252.
Starting in 2015, the U.S. Army Medical Research and Materiel Command paid for a test of TRE1. Researchers in Phoenix randomly assigned veterans with post-traumatic stress disorder (PTSD) to the full routine, to the same stretches and holds without the trembling, or to a waiting list1.
The trembling group and the no-trembling group improved by similar amounts, and the differences among the three groups weren’t statistically significant1.
That doesn’t mean moving can’t calm you. It can, and the proof for ordinary exercise is far stronger than for any viral method. Below, we look at what works, what’s unproven, how to time movement around sleep, and a wind-down for tonight.
Exercise eases anxiety, and harder sessions do a bit more
In 2023, a team led by Ben Singh at the University of South Australia published an umbrella review, a review of other reviews, in the British Journal of Sports Medicine3. It drew on 97 reviews covering 1,039 trials and 128,119 people3.
Compared with usual care, physical activity eased anxiety and depression by a medium amount, and psychological distress by a bit more3. Walking, strength training, Pilates and yoga all helped3. Higher-intensity activity brought bigger gains, and programs of 12 weeks or less showed the strongest effects3. The authors add that people need to keep exercising to keep the benefits4.
Read the fine print, too. Of the 97 reviews, 77 were rated critically low in quality3, and the largest gains were ones participants reported themselves4. The university’s release said activity was 1.5 times more effective than counseling or leading medicines3. That was an indirect comparison: the authors set their results beside earlier reviews of those treatments, with no head-to-head trials, so treat “better than drugs” headlines with caution4.
Federal guidelines agree: the U.S. Department of Health and Human Services lists lower anxiety and better sleep among the immediate benefits of physical activity5.
If you have an anxiety disorder, think of exercise as one strong tool in a kit that may also include therapy or medicine. Don’t stop a treatment that’s working.
If sitting still makes you more anxious, try moving
Lying still and “relaxing” doesn’t suit everyone. The National Center for Complementary and Integrative Health (NCCIH) notes that relaxation techniques occasionally bring on more anxiety, intrusive thoughts or a fear of losing control6.
For a restless body, rhythm can be easier than stillness. A steady walk, a slow stretch or a gentle sway gives your attention something to follow. Mindful walking, covered in our sibling article, is one version of that idea.
NCCIH says yoga, tai chi and qigong can trigger the relaxation response: slower breathing, a slower heart rate and lower blood pressure6. Our articles on yoga and tai chi cover their trials.
This is a useful distinction. Gentle practices can bring on the relaxation response, which suits the moment6. But in the Singh review, harder sessions brought bigger mental health gains over weeks3. So think of two jobs: a brisk walk or bike ride most days to build resilience, and slow, easy movement when you need to settle down, especially at night.
Rocking calms babies, but one small study tried it on adults
Parents rock babies to sleep. In 2019, researchers at the University of Geneva tested the idea on grown-ups7.
The volunteers were 18 healthy young adults at the Geneva University Hospitals sleep center. After a first night to get used to the lab, each slept once on a bed that swayed gently all night and once on the same bed switched off7. Swaying brought sleep on sooner, stretched out deep sleep and cut down on tiny wake-ups7. A memory test told the same story: people recalled more of an evening word list after the moving night7.
A companion study at the University of Lausanne found rocked mice fell asleep sooner and slept longer, though their sleep quality didn’t improve7. Rocking did nothing for mice whose inner-ear balance sensors were disabled, pointing to the vestibular system, the body’s motion sense, as the pathway7.
That’s one night in 18 people, an early clue rather than a treatment. Still, a rocking chair, porch swing or glider in the evening costs little to try. That’s our suggestion, not a tested program.
The shaking trial: what TRE did and didn’t show
The Army-funded trial ran from 2015 to 2018 through the Carl T. Hayden Medical Research Foundation in Phoenix, with veterans who were getting psychiatric care at the VA1. Ninety-two veterans finished it, three in four of them men, with an average age near 501.
The two exercise groups met twice a week for four weeks, in hour-long sessions1. The TRE routine opened with yoga-like leg stretches and lower-leg strength work with the back against a wall, all meant to tire the legs1.
Next, participants lay down and let the trembling run for 15 to 30 minutes, or as long as felt comfortable1. Straightening both legs on the floor ended it whenever they wished1. The comparison group did the same first half, then skipped the trembling1.
On a standard PTSD scale, the full-TRE group’s average score fell from about 33 to 30, the no-trembling group’s from about 31 to 27, and the waiting list’s barely moved1. The main hypothesis, that trembling would beat the other arms, wasn’t supported1.
TRE beat the waiting list on a memory test, and the report counts an insomnia benefit that was only a statistical trend1. It describes no correction for testing many outcomes1. The results come from the team’s final report to the Army, not a peer-reviewed journal article. Berceli was the only person checking that sessions followed the method, and the yearly reports logged 28 adverse events without describing them1.
A 2023 scoping review from the University of Pretoria found 18 studies of TRE, many with weak designs, and called the results preliminary8.
“Somatic” just means “of the body.” A workout isn’t a therapy
Mayo Clinic Press defines somatic exercise as movement that shifts your attention from thoughts to body sensations9. That includes interoception, the sense of signals from inside you such as heartbeat or hunger, and proprioception, the sense of where your body is in space9.
The word covers two very different things.
Somatic experiencing is a body-focused trauma therapy developed by therapist Peter Levine9. In a trial published in 2017 in the Journal of Traumatic Stress, 63 people with PTSD were randomly assigned to 15 weekly sessions or a waiting list10. The therapy group’s PTSD and depression scores improved by large amounts, and the gains held when people were checked again 15 weeks later10. One trial against a waiting list is promising, not settled.
Somatic workouts online are usually slow, mindful movements done on your own. Tenuto describes micro-movements so small that one 90-minute class she recalls covered just three or four2. She says the practice helps move the nervous system out of fight-or-flight or shutdown and builds new neural pathways2. The CNBC profile quoted no independent expert or study backing those claims2, and Mayo Clinic Press calls the evidence for somatic approaches limited9.
The core idea, that calm can start in the body and not only in the mind, is old and appealing, and it fits how many natural-health readers think about healing. The trouble is the specific promises, such as releasing stored trauma, that haven’t been tested. Slow body-awareness movement is a low-risk way to unwind. Healing trauma is a job for trained help.
Gentle in the evening, hard earlier in the day
Sleep advice has long warned against evening exercise11. In 2018, Jan Stutz and Christina Spengler at ETH Zurich pooled 23 studies of healthy adults to check1112.
After an evening workout, people spent 21.2% of the night in deep sleep, versus 19.9% without one, a small but statistically significant gain12. None of the studies linked moderate exercise to worse sleep, including sessions that finished half an hour before lights out12. Only hard exercise raised a flag, and only in one study. When a vigorous session ended within an hour of bedtime, sleep came more slowly, and heart rates stayed over 20 beats a minute above resting12.
A 2025 study added real-world data. Researchers at Monash University in Australia analyzed about 4 million nights from 14,689 physically active people who wore a WHOOP fitness strap1314. Exercise that ended within four hours of bedtime, especially hard exercise, went with later and shorter sleep, poorer sleep quality and a higher heart rate overnight13. Workouts that ended at least four hours before sleep showed no link to sleep changes, however hard they were14.
Two cautions apply. Researchers from WHOOP, which makes the strap, analyzed the data alongside the Monash team, and the study tracked habits rather than assigning workouts, so it can’t prove cause13. It also didn’t report a separate result for gentle exercise; its lead author suggested brief, low-intensity activity if you must move close to bedtime13.
Put together, the two lines of evidence point the same way: easy movement late is reasonable, and hard workouts belong earlier. Our upcoming sleep articles cover bedtime routines in depth.
Match the movement to the stress
This is our own guide, built from the studies above. Moderate effort means you can talk but not sing12. Very easy means you could sing.
| If you feel… | Try | How much | Why | Adapt or skip if |
|---|---|---|---|---|
| Wired after work, hours before bed | Brisk walk, bike ride or jog | 20 to 30 minutes; can talk but not sing | Regular moderate-to-vigorous activity has the strongest anxiety evidence3 | It’s within 4 hours of bed and your sleep suffers13 |
| Restless near bedtime | The 10-minute wind-down below | About 10 minutes; could sing | Moderate exercise didn’t hurt sleep, even close to bed12 | Any move causes pain |
| Too keyed up to sit and meditate | Mindful walking or slow rhythmic movement | 10 to 20 minutes | Still relaxation can raise anxiety in some people6 | You’re near traffic; stay eyes-up |
| Tight neck, jaw or shoulders at a desk | Shoulder rolls, tense-and-release, a short stretch | 2 to 5 minutes, a few times a day | Our suggestion; not tested as a program | Pain spreads or you feel numbness |
| Worried most days for weeks | A regular exercise plan plus a clinician visit | Most days, for 6 to 12 weeks or longer4 | Trials show medium effects3 | Never as a replacement for treatment |
| Troubled by trauma memories | A trained trauma therapist, with gentle movement alongside | As your therapist advises | Somatic Experiencing had promising results in one trial10 | Shaking or any practice brings on panic or flashbacks6 |
A 10-minute wind-down routine
This routine is our own design, not a tested program. Keep every step very easy: you should be able to sing. Do it on a carpet or mat, or seated.
- Minutes 0 to 2: Loose walk. Walk slowly around the room or in place. Let your arms swing and your jaw hang loose.
- Minutes 2 to 4: sway. Stand with feet hip-width apart. Shift your weight slowly from foot to foot, like a gentle rocking, about one shift per breath. Hold a counter if your balance is shaky.
- Minutes 4 to 5: Roll and release. Roll your shoulders back five times. Then make fists and lift your shoulders toward your ears for five seconds, and let everything drop. Repeat twice.
- Minutes 5 to 7: Easy stretches. Reach both arms overhead, then let them float down. Turn your head slowly to each side. Fold forward from the hips with soft knees and let your arms hang. Skip the fold and the knee hug below if a clinician has told you to avoid bending forward.
- Minutes 7 to 9: Floor rock. Lie on your back and hug your knees toward your chest. Rock slowly side to side, letting your lower back rub the floor.
- Minutes 9 to 10: rest. Set your feet on the floor, knees bent. Rest one hand on your belly and let each out-breath run a little longer than the in-breath.
Seated version: Sit in a sturdy chair without wheels. March your feet in place, sway side to side from the hips, do the shoulder rolls and fist squeezes, then rest with your hands on your belly.
What the evidence says, rated
| Claim | What studies found | Evidence level |
|---|---|---|
| Regular exercise eases anxiety symptoms | Consistent medium effects across 1,039 trials, though 77 of 97 reviews were rated critically low in quality3 | |
| Activity brings quick relief from anxiety | The federal Physical Activity Guidelines list it among immediate benefits5 | |
| Rocking helps adults sleep | One night in 18 young adults7 | |
| Somatic Experiencing therapy eases PTSD | One 63-person trial against a waiting list10 | |
| TRE relieves PTSD or stress | 18 mostly weak studies; in the one controlled trial, the shaking added nothing over stretching alone18 | |
| Social-media somatic workouts rewire trauma or the nervous system | No trials cited for these claims29 | |
| Moderate evening exercise ruins sleep | No harm across 23 lab studies, even 30 minutes before bed1112 | (the claim failed testing; no safety issue) |
| Hard exercise late in the evening can disturb sleep | One small lab study plus large observational wearable data, co-analyzed by the device maker1213 |
Questions readers ask
Is a hard workout or a gentle one better for anxiety?
For mental health gains over weeks, the Singh review found that higher-intensity activity did more3. Gentle movement is better suited to settling down in the moment, especially near bedtime. You can do both.
Can I try TRE at home?
In the trial, participants could stop the trembling any time by stretching their legs flat1. But the only controlled test we found showed no edge over the same exercises without shaking1. If you have PTSD or a trauma history, work with a mental health professional rather than on your own.
Does exercise replace anxiety medicine or therapy?
No. Exercise has good evidence as one part of care, but most trials compared it with usual care, not with proven treatments head to head3. Talk with your clinician before changing any treatment.
The bottom line
Moving is one of the best-supported ways to ease anxiety and stress, and you don’t need a special method to get the benefit. Regular brisk activity does the heavy lifting over weeks, while slow, rhythmic movement can help you settle in the moment and at night.
The newer labels deserve a gentler verdict: interesting, mostly harmless, and unproven. In the only controlled test, the shaking in TRE added nothing over stretching, and we found no trials of online somatic workouts. Save hard workouts for earlier in the day, keep anxiety care in place, and reach out for help if stress becomes a crisis.
