Although anger feels like a big dominant emotion for most people, in psychology it is often viewed as a secondary emotion. This means that anger is an easily accessed and primal response while behind it are the true triggering emotions such as frustration, abandonment, loneliness, and loss.
As a biological response, anger releases huge amounts of cortisol and adrenaline into the bloodstream, which over the long term, interfere with the body’s ability to heal itself.
Occasional anger is fine for the body — as long as there is a recovery time for the body to clear itself of cortisol and adrenaline. Constant and building anger are detrimental to the body and often are ignored because a person has become accustomed to living in a toxic and over-stimulated environment.
