What it is
Progressive muscle relaxation is exactly what it sounds like: you move through the body, tensing one muscle group at a time for a few seconds, then letting go completely and noticing the difference. Developed by physician Edmund Jacobson nearly a century ago, it's one of the most robustly studied relaxation techniques there is, with good evidence for reducing anxiety and improving sleep.
Why tensing first actually helps
It seems backwards to tense up in order to relax — but there are two reasons it works. First, a muscle released after deliberate contraction settles below its starting level of tension. Second, and more importantly, the sharp contrast between "tight" and "loose" trains your ability to notice tension you normally carry without realizing it. Most of us clench our jaw, shoulders, or brow all day without knowing. PMR teaches your body what released actually feels like.
The basic sequence
Find somewhere you can sit or lie undisturbed. For each group: tense firmly (but never to the point of pain) for about five seconds, then release and rest for fifteen to twenty seconds, noticing the sensation of the tension draining away. Breathe normally throughout — don't hold your breath.
A standard order:
- Hands (make fists)
- Arms (tense the biceps)
- Forehead (raise eyebrows), then eyes and cheeks (scrunch)
- Jaw (gently clench)
- Neck, then shoulders (lift toward ears)
- Chest, then stomach
- Buttocks, then thighs, then calves (point toes toward you), then feet (curl toes)
When to use it
PMR shines for physical, wound-up tension and for winding down before sleep. If your anxiety lives in your body — tight chest, clenched jaw, restless limbs — this gives it somewhere to go. For a racing mind, a present-moment or breathing practice may serve you better, and you can combine them.
One safety note
Go gently on any area that's injured or painful, and keep every contraction light if you have muscle or joint conditions. The goal is a firm squeeze, never a strain.
