Do you know that each child in school catches six to ten colds every year? Though there is no cure for colds, there are some suggestions for you to avoid getting a cold.
First, you can avoid catching a cold by practicing healthy habits. Begin by eating healthy foods. Eat lots of fruits and vegetables and drink milk and juice. Other healthy habits include getting plenty of sleep at night and lots of exercise.
Next, you should try to avoid contact with the viruses that cause colds. If you can, stay away from large crowds. When people cough(咳嗽) and sneeze(打喷嚏), the cold virus goes into the air. Do not share a drinking cup, fork, or spoon with someone else because that could spread the virus. Washing you hands is also a good way not to catch a cold. The cold virus may be on the things like telephones and money. Shaking another person’s hand could even spread the virus. By washing your hands, you can stop the virus from infecting(传染).
