There are a few simple steps you can use to relax yourself in situations that make you angry. Try them to find out which ones are the best for you personally.
After you found the technique that you think works best for you, practice daily. Eventually, you will be able to use them automatically.
1. Breathe deeply, from your diaphragm. Breathing from your chest won’t relax you, so picture your breath coming up from your “gut.”
2. Slowly repeat a calming word or phrase, such as “relax” or “take it easy.” Keep repeating it to yourself while breathing deeply.
3. Use imagery. Visualize a relaxing experience from your memory or your imagination.
4. Try non-strenuous, slow exercises. Yoga and similar activities can relax your muscles and calm you down.
