Coughing, although it can be annoying, actually a mechanism of defense of our body, namely, to protect and clean the respiratory system. The viruses of cold are usually the main responsible for the cough, but are not the only triggers. Snuff smoke, irritants in the environment, can also make us cough. It should be noted that, under the generic name of cough, different types are included. Thus, the cough may be dry or productive, depending on its duration, acute or chronic.
Coughing is not a disease itself but a symptom and a defense mechanism, like a reflex, is involved in our respiratory system to expel foreign agents, such as cold viruses, one of the most common respiratory diseases during the cold months. Cough, although it may be uncomfortable, therefore plays an important role, at the time that alerts us that we look for the cause that causes it. Not only respiratory infections can make us cough, also the snuff smoke or other irritants in the environment.
