A. Get out. Some experts say that we usually feel bored or sad because we get less sunlight in winter than we do in other seasons. Getting more sunlight each day can help you feel better.
B. To keep healthy, you can do some exercise. If you don't like doing sports outside, you can do some sports at home. The best way is that you had better receive the flu vaccine (流感疫苗).
C. Eat healthily. Avoid eating too much. If you get hungry easily, you can have more small meals rather than a larger one, and you can eat more fruit and vegetables.
D. Let your stress go. Cut back if you have too many things to do. Make sure you have some quiet time to yourself. Don't be so busy, or you may do anything wrong.
E. Get enough sleep. If you don't have enough sleep, you will not think clearly. So from now on, you need to have a good sleeping habit and go to bed earlier.
F. Relax yourself. The more excited or nervous you are before you sleep, the more bad dreams you will have. Do something relaxing to make sure your brain is peaceful, such as reading and listening to music.
