What is cough?

Coughing indicates that our respiratory passages are overtaxed.

Often, it is only a harmless reaction, such as when we have swallowed something the wrong way.

Coughing is our body's way of trying to get rid of foreign bodies and to normalize conditions in our respiratory tract.

But coughing can also be a warning signal from the bronchi, indicating an underlying illness such as an infection.

Although there are not usually a large number of pathogenic germs in our respiratory system, the conditions for viruses and bacteria improve if dust or dirt enters the lungs.

Especially if the immune system is weakened, the germs will be able to multiply and spread. This can lead to an infection of the respiratory tract and a build-up of phlegm.

Coughing is the body's response to this.
