Anger is good for you, as long as you control it properly, according to new psychology research. A new study from Carnegie Mellon University shows anger may help people reduce the________   effects of stress and help you become healthier.

“Here getting _______ is not bad for you if you look at the case of anger.” Said Jennifer Lerner of Carnegie Mellon. “The more you display anger, the lower their stress ________are.”Lerner studied 92 UCLA students by asking them to count back from 6,200. They must say out loud every 13^th number. Researchers ________ them by asking them to count faster or ask them other questions. If they made any mistakes, they had to ________ from the very beginning. Many students felt ________ about making so many mistakes or got angry because the researchers were interrupting them.

Lerner used a ________ video camera and recorded all their facial expressions during the test. The researchers described their ________ as fear, anger and disgust. Other researchers recorded the students’ blood pressure, pulse and production of a high- stress hormone called cortisol(皮质醇).

People whose faces showed more fear during the experiment had higher blood pressure and higher levels of the hormone, which both can have________ effects such as diabetes (糖尿病), heart disease, depression and weight gain. Therefore, when people fear, negative impacts increase. ________ when they get angry, those negatives ________, according to the study. “ Having that sense of anger leads people to ________ feel some power in what otherwise is a maddening(令人发狂的) situation.” Lerner said.

Lerner ________ had studied Americans’ emotional response to the 9/11 terrorist attacks two months after the incident. He found people who reacted with anger were more ________. These people are healthier compared with those who were frightened during the event.
