This happens when you hold in your anger, stop thinking about it, and focus on something positive. The aim is to inhibit or suppress your anger and convert it into more constructive behavior. The danger in this type of response is that if it isn't allowed outward expression, your anger can turn inward-on yourself. Anger turned inward may cause hypertension, high blood pressure, or depression. This inward response is both physically and psychologically unhealthy.
Unexpressed anger can create other problems.
People who are constantly putting others down, criticizing everything, and making cynical comments haven't learned how to constructively express their anger. Not surprisingly, they aren't likely to have many successful relationships. These people are difficult to be around. Finally, you can calm down inside. This means not just controlling your outward behavior, but also controlling your internal responses, taking steps to lower your heart rate, calm yourself down, and let the feelings subside.
