     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.

     Anger is a normal emotion that we all feel from time to time. 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. In general the person feels excited and

ready to act. Some doctors say that both repressing and expressing anger can be dangerous. They believe that

those who express anger ferociously may be more likely to develop heart disease, and they believe that those

who keep their anger inside may face a greater danger of high blood pressure.

     Doctors say the solution is learning how to deal with anger. They say the first step is to admit that you are

angry and to recognize the real cause of the anger, then decide if the cause is serious enough to get angry about.

If it is, they say, "Do not express your anger while angry. Wait until your anger has cooled down and you are

able to express yourself calmly and reasonably."

     Doctors say that a good way to deal with anger is to find humor in the situation that has made you angry.

They said that laughter is much healthier than anger.
