The concept of 4 stages of anger is a widely accepted framework for understanding and managing anger. Everyone experiences these stages differently, and some individuals may skip certain stages or cycle through them repeatedly. Here are the four stages:

1. Triggering Event: This is an initial incident or situation leading to a feeling of anger. It is the event that provokes or sets-off the anger response.
2. Activation: In this stage, physiological changes occur in the body and can include a faster heart rate, rising blood pressure, increased muscle tension, and the release of stress hormones like adrenaline. These physical changes prepare the body for a “fight or flight” response.
3. Expression: This is the phase where anger is expressed in some form, for example, verbally or physically, or in some cases it is suppressed or repressed which can lead to problematic long-term emotional and health impacts.
4. Resolution: This is how an individual manages and handles their anger. If poorly dealt with, it might hurt relationships and increase stress and health problems. Ideally, constructive, positive solutions should be pursued, and professional help sought if needed.

Over time, some researchers and therapists have expanded upon or slightly adapted this concept. The research article, “Control Excessive Anger before it Controls Your Life” is one example of that. The important thing is knowing that learning to manage and express anger in a healthy manner can lead to better emotional and interpersonal outcomes. Anger Management Therapy helps individuals to recognise and understand anger progression stages as a foundation for developing appropriate strategies for controlling and expressing this emotion.
