Progressive muscle relaxation (PMR): a definition

Progressive muscle relaxation (PMR) is a technique for easing physical tension: you tense one muscle group at a time, hold briefly, then release completely, moving through the body in sequence. Physician Edmund Jacobson developed the method and published it in 1929. A 2026 meta-analysis of randomized controlled trials links PMR to better sleep and lower anxiety.

Who created progressive muscle relaxation?

Edmund Jacobson, an American physician and physiologist, spent over a decade measuring muscle tension in patients with lab instruments before publishing the full method in his 1929 book, Progressive Relaxation (University of Chicago Press). His theory: physical tension and mental tension feed each other, so learning to release the body gives the mind less to hold onto. He later distilled the method for general readers in a 1934 book, You Must Relax.

How do you do progressive muscle relaxation?

The classic sequence hasn’t changed much since Jacobson’s day:

Pick a muscle group, starting with your feet or hands.
Tense it firmly for about 5 to 10 seconds, without straining to the point of pain.
Release it completely, and notice the difference between tense and loose.
Rest for 10 to 20 seconds, then move to the next group.
Work through the body, feet to head or the reverse, until you’ve covered the major muscle groups.

A full pass typically takes 15 to 20 minutes, though shorter versions targeting just a few tight areas work too.

Deliberately tensing muscles isn’t right for everyone: the Cleveland Clinic advises skipping or modifying the exercise if you have a recent injury, muscle spasms, back problems, or uncontrolled blood pressure, and checking with a doctor first if you’re unsure.

Does progressive muscle relaxation work?

Yes, with a solid and growing evidence base. A 2026 meta-analysis of randomized controlled trials, published in the Journal of Psychosomatic Research, found PMR significantly improved sleep quality and reduced anxiety compared with control groups. A 2024 systematic review in Psychology Research and Behavior Management reached a similar conclusion for stress, anxiety, and depression in adults. The NIH’s National Center for Complementary and Integrative Health includes PMR in its overview of relaxation techniques, describing the same tense-then-release mechanism.

Is progressive muscle relaxation the same as EMDR?

No. PMR relaxes the body through sequential muscle tension and release; it isn’t built around a specific memory. EMDR instead uses bilateral stimulation: alternating left-right eye movements, taps, or tones, held in mind alongside one target memory, an approach the American Psychological Association conditionally recommends for PTSD. Both can calm an overwhelmed body, which is why some people use a few rounds of PMR to settle physically before or after a bilateral-stimulation session rather than choosing only one. Either can also help keep you inside your window of tolerance during an ordinary stressful moment.

If you’re carrying tension right now, our muscle-tension release protocol pairs a quick tense-and-release move with bilateral stimulation. EmEase, a self-guided EMDR app, offers guided visual and audio bilateral stimulation at app.emease.com if that mechanism appeals to you more than muscle work alone. The butterfly hug is another simple, no-equipment option worth knowing. And if a specific memory, not just everyday tension, is behind the distress, see can you do EMDR on yourself for where self-help reaches its limit.

Frequently asked questions

What is progressive muscle relaxation (PMR)?

PMR is a technique for easing physical tension: you deliberately tense one muscle group, like your fists or shoulders, for a few seconds, then release it completely and notice the contrast. You repeat this through the major muscle groups, head to toe or the reverse, which trains you to recognize and release tension on your own.

Who invented progressive muscle relaxation?

Physician and physiologist Edmund Jacobson developed it in the early 1900s, using lab instruments to measure muscle tension in patients. He published the full method in his 1929 book Progressive Relaxation, then a shorter version for general readers, You Must Relax, in 1934.

Does progressive muscle relaxation actually work?

Evidence is solid and growing. A 2026 meta-analysis of randomized trials, in the Journal of Psychosomatic Research, found it significantly improved sleep quality and lowered anxiety. A 2024 systematic review in Psychology Research and Behavior Management reached a similar conclusion for stress, anxiety, and depression.

Is progressive muscle relaxation the same as EMDR or bilateral stimulation?

No. PMR relaxes the body by tensing and releasing muscles in sequence. EMDR uses bilateral stimulation instead: alternating left-right eye movements, taps, or tones held in mind alongside a specific memory, an approach the American Psychological Association conditionally recommends for PTSD.

Is progressive muscle relaxation safe for everyone?

For most people, yes, with no equipment and little downside. But deliberately tensing muscles isn't right for everyone: skip or modify it if you have a recent injury, muscle spasms, back problems, or uncontrolled blood pressure, and check with a doctor first if you're unsure.

How long does a progressive muscle relaxation session take?

A full sequence through all the major muscle groups typically takes 15 to 20 minutes. Shorter versions exist too: some people work through just a few groups, like hands, shoulders, and face, in under five minutes, though the full-body version is what most research has tested.
