Progressive muscle relaxation

Systematically tensing a muscle group for a few seconds and then releasing it, working through the body.

Reported trial effects

Trials consistently report less anxiety and better self-reported sleep after progressive muscle relaxation, but the published effect sizes are implausibly large for a relaxation intervention, with pooled estimates far exceeding those seen for established treatments.

Limits and effect size

Heterogeneity is very high in both the anxiety and sleep meta-analyses, and most trials compared progressive muscle relaxation with routine care, a waitlist, or no treatment rather than an active control, so non-specific attention and expectancy effects are not excluded. The honest reading is that this is a safe, free practice with a consistent but overstated evidence base: it may help, it will not help as much as the headline numbers suggest, and the specific contribution of the tensing-and-releasing method over simply resting quietly is unproven.

Comparison for scale

For scale, cognitive behavioural therapy for insomnia delivered in routine primary care and community settings produces small to moderate effects (Pittsburgh Sleep Quality Index weighted effect size 0.37; Cheung 2019, doi 10.1016/j.smrv.2018.11.001), well below the pooled progressive muscle relaxation estimates.

Outcome assessments based on research, including its uncertainties and limitations.

Anxiety symptoms

Finding: Benefit supportedCertainty: Limitedstudies found a benefit from doing this

Evidence basis: randomised trials

Meta-analytic and systematic-review evidence consistently points to reduced anxiety after progressive muscle relaxation training, but the effect estimates are large, imprecise and highly heterogeneous.

Population: Adults across mixed settings: 31 randomized trials with 2,277 patients in the 2026 meta-analysis; 27 studies in the 2008 relaxation meta-analysis (1997-2007); 46 publications from 16 countries covering more than 3,402 adults in the 2024 systematic review, mostly university students, nurses and healthcare workers, older adults and patients with physical illness.

Research details

Summary

Meta-analytic and systematic-review evidence consistently points to reduced anxiety after progressive muscle relaxation training, but the effect estimates are large, imprecise and highly heterogeneous. A 2026 meta-analysis of 31 randomized trials (2,277 patients) reported an anxiety standardized mean difference of -1.11 (95% CI -1.69 to -0.53, I2 = 85%), and a 2008 meta-analysis of 27 relaxation studies found a between-group Cohen's d of .51 (95% CI .46 to .634). A 2024 systematic review of 46 publications covering more than 3,402 adults concluded that PMR reduces stress, anxiety and depression. Most individual trials compare PMR with routine care or no intervention rather than an active control.

Why this certainty

Rated Limited: the direction is consistent across two independent meta-analyses and one large systematic review, but heterogeneity is very high (I2 = 85%, I2 = 92.1% for sleep in the same review), effect sizes are implausibly large for a relaxation intervention, and the comparator is usually no treatment or routine care rather than an active control, so non-specific effects of attention and expectation are not excluded. Small samples and high risk of bias limit confidence in the magnitude.

Limitations

Much of the literature is older with small samples and unclear blinding; in the 2024 review, designs were a mix of randomized and quasi-experimental studies, many anxiety findings rest on within-group pre-post change rather than between-group comparison, and several included trials (for example Avants 1990, Jermaina 2022, Mustafa 2021) found no significant anxiety reduction. Reporting of allocation concealment and blinding at item level could not be confirmed from the material retrieved.

Effect estimate

Anxiety: SMD -1.11 (95% CI -1.69 to -0.53; I2 = 85%) in 31 RCTs (Donato 2026). Relaxation training (including Jacobson's progressive relaxation, autogenic training, applied relaxation and meditation) for anxiety: between-group Cohen's d .51 (95% CI .46 to .634) and within-group d .57 (95% CI .52 to .68) in 27 studies (Manzoni 2008).

Sleep quality and sleep problems (subjective)

Finding: Benefit supportedCertainty: Limitedstudies found a benefit from doing this

Evidence basis: randomised trials

Progressive muscle relaxation improves self-reported sleep quality in adults, with the largest pooled estimates in non-cancer and younger populations and no significant improvement at 55 years and older.

Population: Adults in randomized controlled trials: 957 participants in 14 trials (cancer and non-cancer populations, adults younger and older than 55 years) and 2,277 patients in 31 trials; individual trials include postmenopausal women, patients undergoing chemotherapy and healthcare practitioners.

Research details

Summary

Progressive muscle relaxation improves self-reported sleep quality in adults, with the largest pooled estimates in non-cancer and younger populations. A 2026 meta-analysis of 14 randomized trials (957 participants) reported Hedges g = -1.24 (95% CI -1.71 to -0.77, I2 = 85.5%), with benefit in cancer patients (g = -1.17, 95% CI -2.24 to -0.09) and non-cancer patients (g = -1.29, 95% CI -1.94 to -0.65), but no significant improvement in adults aged 55 years and older (g = -1.17, 95% CI -2.67 to 0.32). A separate 2026 meta-analysis of 31 RCTs (2,277 patients) found sleep quality SMD -1.74 (95% CI -2.14 to -1.34) and PSQI mean difference -3.79 (95% CI -4.78 to -2.79).

Why this certainty

Rated Limited: two independent 2026 meta-analyses agree on direction and statistical significance, but both are dominated by small, unblinded trials with very high heterogeneity, several included trials are in specific clinical populations, and the absence of an active-control comparison means the specific contribution of PMR over general relaxation or attention is unproven. Sleep quality is retained as a felt/subjective outcome, separate from the anxiety and stress outcomes.

Limitations

Heterogeneity is very high (I2 = 85.5% and 92.1%), most outcomes are self-report questionnaires such as the PSQI with no blinding of participants, and many trials use routine-care or waitlist comparators rather than an active control, so expectancy and attention effects cannot be excluded. Effect sizes of this magnitude are larger than those reported for cognitive behavioural therapy for insomnia delivered in routine primary care and community settings (Pittsburgh Sleep Quality Index weighted effect size 0.37; Cheung 2019), and the number of PMR sessions was not associated with effect size (meta-regression p = 0.2106), which does not fit a straightforward dose-response explanation.

Effect estimate

Sleep quality: Hedges g = -1.24 (95% CI -1.71 to -0.77, p < 0.001, I2 = 85.5%) in 14 RCTs (Li 2026). Sleep quality: SMD -1.74 (95% CI -2.14 to -1.34; I2 = 92.1%) and PSQI mean difference -3.79 (95% CI -4.78 to -2.79; I2 = 94.2%) in 31 RCTs (Donato 2026).

Sources for this outcome:

Perceived stress

Finding: Benefit supportedCertainty: Very limitedstudies found a benefit from doing this

Evidence basis: indirect evidence, not a direct test of this exact habit

Progressive muscle relaxation is reported to reduce perceived stress, but the evidence is a systematic review with no pooled estimate and effect sizes drawn from mostly uncontrolled studies.

Population: Adults in 46 publications from 16 countries (more than 3,402 adults), including university and medical students, nurses and other healthcare workers, athletes, caregivers and older adults.

Research details

Summary

Progressive muscle relaxation is reported to reduce perceived stress, but the supporting evidence is a systematic review without pooled meta-analysis and individual effect sizes come from small studies that are mostly pre-post or uncontrolled. A 2024 systematic review of 46 publications covering more than 3,402 adults concluded that PMR is effective in reducing stress, anxiety and depression, with effects appearing larger when PMR is combined with another intervention. No pooled stress estimate exists; within-study effect sizes reported by Khir 2024 range from d = 0.29 to d = 4.31 across uncontrolled and quasi-experimental designs in populations including nurses, medical students, athletes and older adults.

Why this certainty

Rated Very limited: the only directly retrieved evidence is a narrative systematic review conclusion plus individual study effect sizes derived without pooling, mostly from uncontrolled or quasi-experimental designs. Direction is consistent but there is no precise pooled estimate with a confidence interval, so both magnitude and causal attribution remain uncertain. Perceived stress is kept separate from anxiety because it is a distinct construct with distinct instruments (for example the Perceived Stress Scale). The outcome is recorded as Indirect evidence rather than Randomized intervention because no randomised between-group stress contrast was retrieved: the pooled designs in the sources are uncontrolled pre-post or quasi-experimental.

Limitations

Stress findings are largely within-group pre-post changes rather than controlled between-group comparisons, the review used Joanna Briggs Institute checklists to grade study quality but did not pool stress data in a meta-analysis, and many included studies were quasi-experimental. Effect sizes up to d = 4.31 are implausibly large and suggest measurement or reporting problems, and the review only included high- and moderate-quality studies by its own threshold, so the appraisal detail is limited.

Practical steps and precautions

How to try it

  1. Sit or lie somewhere quiet; tense one muscle group for about 5 to 10 seconds, release for about 10 to 15 seconds, and notice the difference before moving to the next group (editorial starting point modelled on the trial protocol, not a validated dose).
  2. Work through the major groups in order, for example hands and arms, then shoulders and neck, then face, chest, abdomen, and legs.
  3. A single session of roughly 15 minutes is a reasonable editorial starting point; trials ranged from one session to eight weeks and meta-regression found no association between the number of sessions and sleep improvement.
  4. Use it before bed if sleep is the goal; the sleep trials typically delivered the practice in the evening.

Precautions

  • Do not tense hard through an injured, painful, or post-surgical area; use a much gentler contraction, or skip that muscle group, and get advice from a clinician or physiotherapist if in doubt.
  • Tensing muscles can briefly raise blood pressure and heart rate, so keep contractions mild if you have uncontrolled hypertension or a cardiovascular condition.
  • Stop if the practice makes you feel more anxious, dizzy, or light-headed; a minority of people find inward-focused relaxation uncomfortable.
  • Progressive muscle relaxation is not a treatment for a diagnosed anxiety disorder or insomnia; the trial evidence is short-term and does not compare it with first-line treatments.

Editorial history and review method

Revision 5 · Approved for publication · Codex (publication approval explicitly authorized by site owner; category migration)

Prepared and checked with AI. Publication approval does not imply independent expert review. Request a correction.

Applied the audit corrections for progressive-muscle-relaxation. (1) Completed two stored, user-visible truncations: the card summary ended mid-sentence at 'with pooled estimates far…' and the perceived-stress headline ended at '…that are mostly…'. (2) perceived-stress was labelled 'Randomized intervention' although the entry's own certainty rationale says the stress findings are mostly uncontrolled or quasi-experimental and its source luo-2024 is a single-group pre-post study; it is now 'Indirect evidence', and the summary and certainty rationale say so explicitly. (3) The 'implausibly large' comparator claim in the verdict was uncited, so cheung-2019-cbti-primary-care has been retrieved, stored and cited from the sleep-quality outcome, giving the comparison a source: CBT-I delivered in routine primary care and community settings produces PSQI weighted effect sizes of 0.37, well below PMR's pooled estimates. (4) The sleep headline now states the null subgroup rather than only reporting it in the summary: no significant improvement in adults aged 55 years and older (g = -1.17, 95% CI -2.67 to 0.32). The effectEstimate null on perceived-stress was left as null, which the audit confirmed is the catalogue's normal convention, but the summary now says no pooled estimate exists. Second reviewer must re-check: (a) the Donato 2026 / Li 2026 overlap, which cannot be quantified without Donato's paywalled full text, and whether sleep quality therefore effectively rests on one meta-analysis; (b) that no retrieved source isolates PMR against an active control, which remains the main limit on causal attribution; (c) that the CBT-I comparator is not read as evidence about PMR itself, since it is a benchmark and not a head-to-head trial. NOTE ON REVISION HISTORY: the revision-3 record for this habit was written by a separate, concurrent truncated-string pass that had already completed the same two strings this pass fixes (the card summary and the perceived-stress headline). This pass read revision 3, so nothing was lost, but these changeNotes replace that record - a second reviewer should not expect a separate revision-3 note.
