In a sense the angry brain and the rational brain are two different species, the reptilian part of the brain gets angry, the uniquely human part of the brain can be rational, they often don't cooperate.

Relaxation, deep breathing, exercise, time out can be ways of putting the rational brain back in control.

Anger can be addictive, not everyone believes catharsis is a good idea, doing it a lot may just make you want to do it more and more.

"How to Deal with Emotionally Explosive People" by Dr A Bernstein has quality, in depth, reasonably readable stuff on it.
