Why can you catch a cold after catching a cold?

See what kind of cold it is, whether it is a viral cold or a cold.

Viruses are caused by cold weather, and viruses prefer dry and cold air, so they will multiply at this time. If their immunity is not high, it is normal to be infected.

Suffering from a cold is a traditional Chinese medicine saying, because cold air enters the human body, and a compromise method adopted by the body in order to discharge it is a cold. The symptoms of the common cold are cough, runny nose, fever and so on. Take these three, for example. When the body is cold, the body will try to rule him out, so it will rule him out by coughing and running nose. And fever is another manifestation. When we are cold, our bodies will automatically tighten their bodies, which is a defense method, but it is not the most effective. When we can't resist tightening the body, the body fluid in the human epidermis will burn through a chemical reaction with a substance, thus raising the temperature of the human body to fight against viruses and bacteria.

Generally speaking, a cold is a protective measure when the human body is stimulated by the outside world. It is not a bad thing, indicating that the human body is very sensitive to external reactions and can fight in time.
