Progressive Muscle Relaxation

PMR, Jacobson relaxation

Tense each muscle group hard for a few seconds, then release completely. Work through the body. Nearly a century old and still one of the most reliable ways to unclench.

01What it is

Edmund Jacobson developed this in the 1920s and 30s and it has barely needed changing. You deliberately tense a muscle group, hold it for five seconds or so, then let go entirely and notice the difference. Then the next group. It is physical, unmysterious, and it works for people who find purely mental practices useless.

02Why it might work

Two mechanisms. Deliberately tensing before releasing produces a deeper release than simply trying to relax, partly through physiological contrast and partly because it teaches you what your baseline tension actually feels like. Most people cannot detect chronic tension until they have felt the difference. It also gives an anxious body something active to do.

03The benefits

Physical, with nothing to believe or visualiseThe most concrete practice in this library.
Teaches you to detect your own tensionThe lasting benefit. You start noticing a clenched jaw during the day.
Good for people who dislike meditationIt feels like an exercise rather than a practice.
Long standing evidence baseOne of the oldest and best studied relaxation techniques, standard in anxiety and insomnia protocols.

04The full guide

  1. Lie down or sit with supportSomewhere you can tense without falling over.
  2. Start with the handsClench both fists hard for five seconds. Notice the tension deliberately.
  3. Release completely and wait fifteen secondsThe pause is not optional. Noticing the contrast is the mechanism.
  4. Work up the bodyForearms, upper arms, shoulders, neck, jaw, face, chest, stomach, buttocks, thighs, calves, feet.
  5. Tense hard but never to the point of painAbout three quarters of your maximum. Cramping is a sign you overdid it.
  6. Finish by lying stillA minute or two doing nothing, noticing the whole body.

05Best time to do it

  • In bed before sleepThe most popular use and a component of CBT for insomnia.
  • After a long day of sittingIt finds accumulated tension efficiently.
  • When anxiety is physical rather than mentalFor a body that will not settle, this beats cognitive work.
  • Not immediately after heavy exerciseMuscles are already fatigued and may cramp.

Before you start, and what to watch for

  • Skip any area that is injured, inflamed or recovering from surgery. Do not tense over an injury.
  • If you get cramps, you are tensing too hard. Three quarters effort, not maximum.
  • People with muscle conditions, or who are pregnant, should get guidance before adopting this as a routine.
  • If deliberate attention to the body is distressing for you, use paced breathing instead.

What the evidence actually says

Progressive muscle relaxation has one of the longer research histories of any technique here, appearing as an active component in trials of anxiety management and as a standard element of cognitive behavioural therapy for insomnia. Evidence is reasonable for reducing physiological arousal and improving sleep onset, generally with modest effect sizes.
