Differential relaxation: stay functional while reducing unnecessary tension

Relax the muscles that aren't involved in what you're doing while keeping the ones that are active.

Why it works

Most anxious people carry tension in muscles unrelated to the task at hand — clenched jaw while typing, tight shoulders while walking. Differential relaxation is the skill of maintaining only the muscle activation necessary for the activity, releasing the rest. This reduces the ongoing physiological load of anxiety without requiring you to stop or perform a full relaxation sequence.

How to do it

1. During a routine activity (sitting in a meeting, walking, cooking), do a brief body scan.
2. Identify which muscles are active for the task and which are unnecessarily tense.
3. Deliberately release the unnecessary tension while keeping the task-relevant muscles engaged.

Evidence

Differential relaxation is a stage in Öst's applied relaxation protocol; the skill of selective muscular relaxation during activity is a clinically established target in anxiety and pain treatment programs. (clinical)

The stage is studied within the AR program as a whole rather than in isolation; evidence for it specifically comes from program-level trials.

Common mistake

Attempting differential relaxation in high-stakes situations before practicing it in low-demand ones — the skill requires low-stakes repetition to become reliable under pressure.
