First, exercise regularly. Everyone used to say that more exercise is good, but now I really feel it. Regular exercise can detoxify through sweat on the one hand, and enhance your immunity on the other. Good health will enhance the resistance to external viruses. My best friend often works out, not only losing weight, but also having strong resistance, which is really good.
Second, protective measures are in place. You know, the air pollution is really serious now. Wear a mask whenever you go out, because there are not only pollutants but also many viruses in the air. Wearing a mask can at least help. Besides, you can go to the drugstore to buy some medicine to prevent colds, just in case, nothing will happen.
There are really many people who are sick this year, and they may even have a fever with a cold. People in hospitals and clinics are really crowded, especially many people. For the sake of yourself and the people around you, you must take preventive measures and don't be careless.
