5、Moods（情緒）, say the experts, are feelings that are likely to become fixed, having effects on one’s outlook （世界觀） for hours, days or even weeks．That’s great if your mood is a pleasant one, but a problem if you are sad, anxious, angry, or simply lonely．

Perhaps the best way to deal with such moods is to talk them out; sometimes, however, there is no one to listen．Modern pharmacology （藥理學(xué)） offers a lot of tranquilizers （鎮(zhèn)靜劑） and anti-anxiety（抗焦慮） medicines．What many people don’t realize, however, is that scientists have discovered the effectiveness of several non-drug methods to make you free from an unwanted mood．These can be just as useful as medicines, and have the added benefit of being non-poisonous．So next time you feel out of sorts, don’t head for the drug store but try the following methods．

    “Of all the mood changing self –help techniques, aerobic exercise（有氧運(yùn)動(dòng)）seems to be the best cure for a bad mood．If you could keep the exercise, you’d be in high spirits,” says Kathryn Lance, author of Running for Health and Beauty．

Researchers have explained biochemical and various other changes that make exercise more effective than drug as a mood- raiser．Physical work such as house-work, however, does little good．The key is aerobic exercise---running, cycling, walking, swimming, or other repetitive activities that increase the heart rate and circulation, and improve the body’s use of oxygen．Do them for at least 20 minutes a time, three to five times a week．
