Progressive Muscle Relaxation: A Step-by-Step Guide for Sleep and Anxiety

Progressive muscle relaxation (PMR) was developed by physician Edmund Jacobson in the 1920s after he noticed that anxious patients consistently displayed elevated muscle tension. His insight: systematically relaxing the muscles produces a corresponding relaxation of the mind.

Nearly a century later, PMR remains one of the most clinically studied and validated non-pharmacological techniques for insomnia and anxiety.

How PMR works

The technique involves deliberately tensing and then releasing muscle groups throughout the body, progressing systematically from feet to face (or face to feet).

The mechanism operates through several pathways:

Reciprocal inhibition. When a muscle releases from tension, the relaxation is more pronounced than if you'd simply tried to relax without tensing first. The contrast heightens awareness of the difference between tension and relaxation states.

Attentional redirection. The deliberate focus required — tense this muscle group, hold, release, notice the sensation — occupies the attentional resources that would otherwise fuel anxious thinking. You cannot simultaneously focus on muscle sensation and maintain a ruminative thought loop.

Physiological downregulation. Repeated cycles of tension and release lower sympathetic nervous system activation measurably — reducing heart rate, blood pressure, and cortisol.

Somatic awareness. Many people carry chronic, unconscious tension — particularly in the jaw, shoulders, and hands — that they don't notice until directed attention reveals it. PMR builds body awareness that can generalise beyond the formal practice.

The evidence

PMR has one of the stronger evidence bases among relaxation techniques:

A meta-analysis in Sleep Medicine Reviews found that relaxation techniques including PMR significantly reduced sleep onset latency and improved subjective sleep quality across multiple studies, with effects comparable to sleep restriction therapy for sleep onset insomnia.

A Cochrane review found PMR effective for anxiety reduction, with effects maintained at follow-up.

PMR is included in most CBT-I (cognitive behavioural therapy for insomnia) protocols as a core component, alongside stimulus control and sleep restriction.

The complete method

Allow 15–20 minutes for a full session. Lie on your back in a comfortable position with arms slightly away from your sides.

For each muscle group: tense for 5–7 seconds, then release and notice the sensation for 20–30 seconds before moving to the next group.

Feet: Curl your toes downward, tensing the soles of your feet. Hold. Release. Notice the warmth and heaviness.

Calves: Point your toes toward your head, tensing your calves. Hold. Release.

Thighs: Press your thighs together or push them down into the floor. Hold. Release.

Abdomen: Pull your stomach muscles in and tighten your core. Hold. Release.

Hands: Make fists, squeezing tightly. Hold. Release. Let your hands fall open.

Forearms: With fists still or wrists flexed, tense your forearms. Hold. Release.

Upper arms/biceps: Bend your arms slightly and flex your biceps. Hold. Release.

Shoulders: Shrug your shoulders up toward your ears as high as possible. Hold. Release. Feel them drop.

Neck: Gently press the back of your head into the pillow or floor, tensing your neck muscles. Hold. Release.

Face — jaw: Clench your teeth and tighten your jaw muscles. Hold. Release. Let your mouth fall slightly open.

Face — eyes and forehead: Squeeze your eyes shut tightly and furrow your brow. Hold. Release. Feel the forehead smooth out.

After completing all muscle groups, spend 2–3 minutes simply noticing the state of your body. Many people fall asleep before completing the sequence.

Common mistakes

Tensing too hard. The goal is deliberate, moderate tension — not straining. Over-tensing (particularly in the neck) can cause cramping or headaches. Aim for about 70% of maximum tension.

Rushing the release phase. The release phase is where the benefit is. Spend at least twice as long on the release as on the tension phase.

Trying to force relaxation. PMR works through observation, not effort. Don't try to relax — just notice what happens after you release. The relaxation emerges on its own.

Giving up too quickly. Like most mind-body techniques, PMR becomes more effective with practice. The first few sessions may feel awkward or produce only modest results. Consistent practice over 2–3 weeks produces noticeably better outcomes.

Shortened version for acute use

When you don't have 20 minutes — during a stressful moment, before a difficult situation, or when waking at 3am — a condensed version targeting four areas works well:

Feet and legs together
Hands and arms together
Shoulders (shrug and release)
Face (squeeze and release)

This takes 3–4 minutes and provides meaningful physiological calming.

Combining PMR with other techniques

PMR pairs well with:

Diaphragmatic breathing: Coordinate the release phase with a slow exhale. The exhale activates the parasympathetic system, amplifying the relaxation response.

Body scan meditation: Use PMR first to release obvious tension, then follow with a body scan to deepen the awareness of relaxed sensation.

Imagery: During the release phase, some people find it helpful to imagine the tension draining from the muscle like water.

Building the habit

The most effective approach is to practise PMR at the same time every night — typically as the last activity before sleep. Consistency builds a conditioned response: over time, beginning the sequence itself starts to trigger sleepiness.

Guided audio versions (widely available on YouTube and apps like Insight Timer) are helpful when learning, as the external timing cues free you from tracking the sequence yourself.
