The alarm stores as well as reacts. Every flare that ends badly teaches it a little, and so does every one you handle gently.

What the research says

In a randomised controlled trial, brief therapist-supported internet treatments teaching either mindful emotion awareness or cognitive reappraisal both reduced problematic anger, with no clear advantage to combining them. Longstanding anger patterns do shift with practice, and more than one route gets there. The programme was short and measured reported anger rather than what happened at home, so it is a modest result rather than a promise.

Strength of evidence: one line of research. A single study, or a theoretical account.
