     A special kind of *flu (H1N1) is now *spreading in many countries, including China. So it’s important to know how to stop catching flu and cold. Here are some suggestions on how to keep away from flu.

1. Wash your hands often. The flu, as with colds, is spread from person to person. The way these *germs are spread is not by breathing them, but by picking them up on our hands and spreading them to our face where they can get into your body. So please remember: wash your hands often and don’t touch your eyes, nose, or mouth.

2. Get enough sleep. Enough sleep is important to the health. Enough sleep will make you energetic and active again. More important than how long you sleep is when you sleep. Studies show that the best spring or summer bedtime is between 9 and 10 p.m. and the best autumn or winter bedtime is between 8 and 9 p.m.

3. Drink water every day. Water helps change food into energy. Water also helps clean out your body. After a night’s sleep, your body really needs water. So it’s important to drink some water after you get up every morning. And drinking enough water could keep your balance of salt. But don't drink water much more than you would, or should.

4. Eat a healthy, balanced diet. Scientists have found out that what people eat affects their health. They advise people to keep a balanced diet and that is to say, you should eat more fruits and vegetables and less meat such as beef and pork. You should also eat less food that is high in fat, like French fries or cookies.

5. Do more exercise. It is surely necessary to take some exercise every day. Studies show that getting lots of exercise makes the heart healthier. That’s why more and more people are becoming active in all kinds of sports and exercise. Through sports and exercise, people become healthier and stronger. So in the morning, you can get up early, go outdoors, breathe the fresh air, and do exercises. When we exercise, our body produces special chemicals that give us energy, and exercise also helps improve our body’s *ability to fight disease.
