     In winter, when the sun hides behind the clouds,everyone feels a bit low. You may be tired and find

you want to sleep all the time. What you may not know is:you are suffering from (患有) SAD (季节性抑郁症).

     But don't worry-it's normal. Colder temperatures and fewer hours of daylight can steal your energy and

put you in a bad mood.

     Read on to find out what SAD is and what you can do to help yourself or those around you.

     These days, Linda,a US teenager spends most of her holidays sleeping instead of doing sports outside.

She has also had trouble concentrating (集中精力) on her homework. When her mother asks her what's

wrong,Linda doesn't know what to tell her. Linda may not realize it yet, but she's suffering from SAD. It

causes people to sleep,eat sweet food and get sad or angry for no reason.

     About 15 percent of American people now suffer from SAD in winter according to the US Department

of Health. The US government has taken measures to help people beat it. Local communities encourage

people to take part in activities such as exercise,dance or art. And they advise people not to eat too much

sweet food.

     Like in the US, cold northern European countries such as Finland, Iceland and Russia see a large number

of people suffer from SAD every year. So, the sunlamp is widely used in these countries. It's an electric lamp

which is just like a "little sun" that gives off light to make people think the sun is shining and feel better.
