Why do you always get sick in winter?

Hello: There are three main reasons. The first reason is that viruses are easy to spread in cold weather, and people have a soft spot for noses. If they are not careful, they will enter our bodies through their noses. So be sure to have a regular physical examination and don't go to some unsanitary places. The second reason is that because winter is too cold, everyone's own resistance will drop, so when there is a little bacteria around, it will invade the body and cause diseases. The third reason is that because of lack of exercise, many people often go to exercise when the weather is warm, but when the weather is cold, they will give up fitness, so the virus takes advantage of it.
