Having one of those days or weeks----when everything seems to annoy you? Even

if you do nothing about it, your bad mood will probably go away after some time. But with a little effort, you can forget it much faster---often within a day or two.

Walk it off

Exercise is the most popular bad-mood buster(破坏者). A person who is in bad mood has low energy and high tension. Taking a fast ten-minute walk, or doing some quick exercises can do wonders towards changing that bad mood.

Tune it out

Listening to your favorite music for a while can also make tension go away quickly, because music starts associations with past positive experiences we’ve had.

Give yourself a pep talk

Stop and listen to what is on your mind. Bad moods are often started by too many negative thoughts. Write them all down on paper; the pessimistic (悲观的) messages you’ve been giving yourself and then give optimistic answers. (“ I still don’t have a job” v.s “ I have two interviews next week.”)

Reduce your stress

Relaxation techniques are wonderful mood-lifters. These include deep breathing, stretching and visualizing (想象),all of which sound complicated but aren’t. One easy way to visualize: close your eyes and picture a favorite place, such as the beach. Another simple way to against distress is to make a to-do list. One reason for being in a bad mood is feeling you have no choices. By taking control over certain areas, you realize you’re not helpless. You can make changes in your mood and life.

Avoid things that won’t improve your mood

TV may not help much: You need to increase your energy level and stimulate(刺激) your mind -----something that the TV show “Neighbors” won’t do. And before you reach for that piece of cake and coffee, think about how mood and food are linked. Sugar and caffeine(咖啡因) contribute to depressed moods. The better choice? Research shows that carbohydrates, such as potatoes and pasta, produce a calming effect in people who have a desire for them.
