In winter and spring, the flu(流感) is a kind of serious illness. In fact, it is hard for you to stay away from it. However, there are some ways to cut down the possibility of catching it.
According to a study, the immune system (免疫系统) in the body doesn't work well in the cold weather, while viruses (病毒) don't like the warm body. So wearing enough clothes may help keep away from them.
Although it's possible for you to keep away from another's coughing, you're more likely to pick up viruses from something you touch. "Wash hands often. If there is no way to clean hands, try not to touch your eyes or nose. " said Dr. Walton. "This is a common way for viruses to get into your body.
When you're sleeping, your body is able to produce something to fight with viruses. People who sleep for seven to eight hours will have a stronger immune system than those who sleep less. According to Dr. Walton, if you can't get enough sleep during the night, a 30-minute daytime nap (打盹) is enough to make up for the bad effect of the poor nighttime sleep on the immune system.
Taking enough exercise can keep the immune system working better. However, doing too much exercise may bring some bad results. For example, you may catch viruses more easily.
To keep away from the flu, having flu jabs (预防针) is necessary and important. "It's true that the jab can't protect us against all kinds of flu, but it can save lives. I'm sure to have one every year, " says Dr. Walton.
A. Get the flu jab in time B. Take control of the body C. Do enough exercise to keep strong D. Keep your hands clean at any time E. Put on enough clothes to keep warm F. Have enough sleep every day |
