Good health is the most valuable thing a person can have. It is important to remember that the body needs proper care in order to be healthy. There are three things that a person can do to help stay in good shape: eat right food, get enough sleep, and exercise regularly.
Proper nutrition (营养) is important for good health. Your body cannot work well unless it receives the proper kind of “fuel”.Don’t eat too much food with lots of sugar and fat. Eat plenty of foods high in protein (蛋白质), like meat, fish, eggs and nuts. Vegetables and fruits are very important because they provide necessary vitamins and minerals. However, don’t overeat. It is not helpful to be overweight.
Getting the proper amount of sleep is also important. If you don’t get enough sleep, you feel tired and easily get angry. You have no energy. Over a long period of time a little amount of sleep may even result in a change of personality (个性). Be sure to allow yourself from seven to nine hours of sleep each night. If you do, your body will feel strong and refreshed, and your mind will be sharp.
Finally, get plenty of exercise. Exercise makes the body strong and prevents you from putting on weight. It also improves your heart and lungs. If you follow a regular exercise program, you will probably increase your life-span(寿命).Any kind of exercise is good. Most sports are very good for keeping the body in good shape: basketball, swimming,bicycling, running and so on,are good examples.Sports are not only good for your body, but they are enjoyable and interesting, too.
If everybody were to eat the right foods, get plenty of sleep and exercise regularly, the world would be a happier and healthier place. We would all live to be much older and wiser.
