Use progressive relaxation to lower resting arousal

Lower your physiological baseline so provocations have less arousal to add.

Why it works

Anger severity is partly a function of pre-existing arousal — a concept called "excitation transfer." When the nervous system is already revved from stress, a provocation adds to an elevated baseline rather than a calm one, producing disproportionate anger. Progressive muscle relaxation and slow breathing reduce resting sympathetic tone, effectively raising the threshold before a trigger pushes arousal into rage.

How to do it

1. Practice progressive muscle relaxation (tensing and releasing major muscle groups) for 15–20 minutes daily, separate from any provocation.
2. Learn a brief version (four large muscle groups) for use when you feel early signs of anger building.
3. Pair relaxation practice with the triggers on your hierarchy, starting with mild ones, to build conditioned calm.

Evidence

Relaxation training as a component of Novaco’s anger stress inoculation protocol has shown significant reductions in self-reported anger and physiological arousal in multiple trials across clinical and forensic populations. A controlled comparison by Hazaleus and Deffenbacher (1986) found relaxation-based treatment reduced anger as effectively as cognitive treatment, and Zillmann’s excitation-transfer work provides the arousal-carryover mechanism this practice targets.

Most trials test multi-component packages rather than relaxation alone; isolating relaxation’s unique contribution is methodologically difficult.

Common mistake

Trying to use relaxation for the first time at the peak of an anger episode — the skill needs daily practice when calm before it can be deployed effectively under provocation.
