Throughout the year, especially in autumn and winter, some people catch a cold several times in a row. At this time, not only do they feel uncomfortable, but they may also infect their colleagues, family, and friends, causing unbearable suffering! In addition, after catching a cold, not only does it delay work, but it can also affect one's mood. At least for a week, they won't get better. Some friends want to get rid of their cold quickly, so they go to the hospital for intravenous infusion. In fact, this is not recommended. A lot of intravenous infusion can lead to more and more frequent colds. Therefore, when dealing with situations where one is prone to catching a cold, it is necessary to improve one's own immunity in order to better resist the next cold attack!
