    As unpleasant emotions go, anxiety is the roughest. It's a vague, pit-of-the-stomach fear that sneaks up to you -- that unease you get when your boss says that she needs to talk to you right away, when the phone rings at 4:00 a.m., or when your dentist looks into your mouth and says "Hmm" for the third time.

Lingering anxiety can keep you up at night, make you irritable, undermine your ability to concentrate, and ruin your appetite. And the constant state of readiness generated by anxiety--- adrenaline pumping, heart racing, palms sweating--may contribute to high blood pressure and heart disease.

How to prevent anxiety then?

Meditate. Maybe you're just high-strung. If so, meditation(冥想) is worth a try. It cultivates a calmness that eases anxious feelings and offers a sense of control. A study at the University of Massachusetts found that volunteers who took an 8-week meditation course were considerably less anxious afterward. People who are high-strung find that they are dramatically calmer with 20 minutes of meditation in the morning and another 20 minutes after dinner.

Jog,walk, swim, or cycle. If you can't make time for meditation, be sure to make time for regular exercise. Exercise can have the same calming effect as meditation, particularly if it's something repetitive like running or swimming laps.

Treatment?

Remember to breathe. When you're anxious, you tend to hold your breath or breathe too shallowly. That makes you feel more anxious. Breathing slowly and deeply can have a calming effect. To make sure that you're breathing correctly, place your hand on your diaphragm(横膈膜), just below your rib cage(胸腔). Feel it rise with each inhalation(吸气) and fall with each exhalation.

Let's say you are anxious about your competence on the job. Ask yourself "What, in particular, am I afraid that I'll mess up?" Maybe you’re afraid that you get further behind and miss your deadlines. Or maybe you're worried that you're blowing it whenever you present your ideas in meetings. Are your worries founded? Have you had several near misses with deadlines? Are your suggestions routinely rejected? If not, the anxiety is needless. If there is a real problem, work on a solution: Pace yourself to better meet deadlines, or join a public speaking class.
