Doctors say anger can be an extremely damaging emotion, unless you learn how to deal with it. They warn that anger can lead to heart disease, stomach problems, headaches, emotional problems and possibly cancer.

  1   Some people express anger openly in a calm reasonable way. Others burst with anger, and scream and yell. But other people keep their anger inside. They can not or will not express it. This is called repressing anger.

For years many doctors thought that repressing anger was more dangerous to a person’s health than expressing it. They said that when a person is angry, the brain releases the same hormones (荷尔蒙). They speed the heart rate, raise blood pressure, or sugar into the blood, etc.   2 

Some doctors say that both repressing and expressing anger can be dangerous. They believe that those who express anger violently may be more likely to develop heart disease, and they believe that those who keep anger inside may face a greater danger of high blood pressure.
