What do you do when you feel unhappy？ Do you listen to music？ Do you talk to a friend？

當你感到不開心的時候你都做什么呢？是聽音樂，還是和朋友聊天傾訴呢？

Maybe next time you feel sad， you should try going outside if it is sunny. Scientists know that sunlight we get can change how we feel.

也許下次當你感到悲傷的時候，如果外面是晴天，你應當出去曬曬太陽。科學家們知道陽光可以改變我們的感受。

Scientists learned this by interviewing people who live in different parts of the world. In the far north， in Alaska or Finland， for example， the days are very short in the winter. People living in these places say that they often feel unhappy in the winter. In the south where there are more daylight hours， fewer people say they are unhappy in the winter.

科學家們通過采訪居住在世界不同地方的人們得出了這個結論。在遙遠的北方，比如，阿拉斯加或者芬蘭，那里的冬天很短。生活在這些地方的人們說，他們在冬天經常感到不快樂。在南方，那里有更多的日照時間，在冬天，那里很少有人說自己不快樂。

The reason is the amount1 of sunlight these people get each day. Sunlight changes the chemicals2 in our bodies， and these chemicals can change the way we feel. A couple of hours of strong sunlight or light from a special lamp can help your body make the chemicals that make us feel happy.

原因是這里的人每天享受到一定程度的日照。陽光改變我們體內的化學物質，這些化學物質可以改變我們的感覺。幾個小時強烈的陽光，或者從一個特殊的燈發出的光，可以幫助你的身體產生使我們感到快樂的化學物質。

Another way to feel happier is to get some exercise. Just like sunlight， regular exercise helps our bodies make certain chemicals， which make us feel happier.

另外一個讓我們感到快樂的方法是做運動。就像陽光一樣，規律的運動也能幫助我們的身體產生特定的化學物質，這些都可以讓我們感到更加快樂。

In addition， exercise helps people sleep better and lack of sleep often makes people feel unhappy.

此外，運動也能幫助人們有更好的睡眠。缺乏睡眠也經常讓人們感到不快樂。

Exercise also helps us get rid of stress. When we are angry or upset about something， exercise is a good way to get those bad feelings out of us.

鍛煉也可以幫助我們遠離壓力。當我們因為某事情感到生氣或者難受的時候，鍛煉是我們遠離那些不好的感覺的一種好方法！
