There are many ways that people work on their anger. Some of these are healthier than others. Anger, resentment, and rage are like venom to people; holding onto to these only leads to an increase of anger/rage/resentment and causes further friction between people. The following are 2 specific groups of techniques used by people to let go of their anger:
Physical Outlets
Some of the best include;
1) writing
2) exercising
3) cleaning/baking/cooking
4) physical construction (hammering, cutting)
5) hitting pillows, mattresses
6) yelling, screaming [not at people]
Calmer techniques
These include the following:
1) relaxation
2) imagery
3) breathing
4) saying calming phrases
All of these techniques lead to a person feeling better. Often times, when people decrease their anger, they find they weren't really angry. It was a mask for depression, anxiety or another feeling. For other people, the recognition that anger is a real feeling is half the battle. It then can allow them to express it in a healthy manner.
