Do you ever find yourself getting really unhappy for almost no reason? Or suddenly feeling down without knowing why? Going from sadness to anger to joy in a matter of minutes can make many teens feel as though they're losing control. But why is the feeling so common among teens?
Maybe you're starting a new school and not able to see old friends as much. Getting good grades or wanting to be better in sports or other activities can be a concern (关注)for many teens. Being accepted by friends is important. Teens also may notice, for the first time, a sense of distance from parents and family. You may feel you want to be on your own and make your own decisions, but it can also seem a bit lonely at times.
Another important cause for mood swings is biology. When puberty begins, the body starts producing hormones（荷尔蒙）. These hormones cause physical changes in the body. But in some people, they also seem to cause emotional(情绪的)changes.
Here are some things you can do that might make those bad moods a bit easier to deal with.
Recognize you're not alone. Although not every teen experiences mood changes to the same degree, they are common.
Talk to people you trust. Friends can help each other by realizing that they're not alone in their feelings. Talking to parents is important, too. Parents can share their own experiences dealing with bad moods. Teachers are often good resources and a doctor can help to answer questions about development.
Get enough sleep. Though it can be hard to find enough time, getting enough rest is very important. Being tired can lead to more sadness.
Create. Taking part in some kinds of activities, like building something out of wood, or starting an art or music piece. Writing can help you organize and express your thoughts and feelings. Get your thoughts on paper. Do the same thing with paint, music, or other art forms. Put your feelings into your artwork.

Old age may not sound exciting. But recent findings offer good news for older people and for people worried about getting older. Researchers found that people become happier and experience less worry after they reach the age of fifty. In fact, they say by the age of eighty-five, people are happier with their life than they were when they were eighteen years old.
The researchers asked questions about emotions like happiness, sadness and worry. They also asked about mental or emotional stress. They also found that levels of stress were highest among adults between the ages of twenty-two and twenty-five.The findings showed that stress levels dropped sharply after people reached their fifties.
The study also showed that men and women have similar emotional patterns as they grow older. However, women at all ages reported more sadness, stress and worry than men.
Researchers say they do not know why happiness increases as people get older. One theory is that, as people grow older, they grow more thankful for what they have and have better control of their emotions. They also spend less time thinking about bad experiences.
