For many people, winter depression, the most common type of Seasonal Affective Disorder (SAD), is as much a part of the season as hats and scarves.      Winter serious SAD sufferers may need medical treatment. Those feeling a little depressed can help themselves by sticking to a healthy lifestyle. Here are some tips:      Pace yourself. Don’t expect to do everything you normally can. Set a realistic schedule. Don’t listen to negative thinking, like blaming yourself or expecting to fail.      Get involved in activities that make you feel good or feel like you’ve achieved something. For example, play table tennis or badminton.      If you are feeling depressed, you may feel like staying away from friends. Yet this is a time when friends support can be helpful. Call them regularly. Remember, the more we put off calling or visiting a friend, the harder it is to rebuild a friendship.      Think clearly about what’s wrong or right. Instead of giving in to vague(含糊的) feelings of sadness, look at your problems objectively. Break down problems into specific issues that you can work on.      Regular exercise helps to prevent and ease depression.      Eat well. Studies show that a healthy diet can help to maintain a healthy body and mind. The vitamins, minerals and micro-nutrients found in a balanced diet may help our bodies to produce feel-good hormones. Foods containing chemicals to help produce feel-good hormones（荷尔蒙） include bananas, turkey, nuts and seeds. Eat at least five pieces of fruit and vegetables every day.      P.S.
