Can we say that the body protects your health and makes you sneeze and cough?

Yes, sneezing and coughing are protective phenomena for our body. When the smallest particles enter the nasal cavity, they irritate the nasal and nasopharyngeal mucosa. The body tries to get rid of them as quickly as possible. Similar sensations arise when small particles enter the larynx and pharynx. After all, if the body does not get rid of them, then the particles will enter the lungs and can cause harm. Likewise, the body gets rid of mucus in the nose and bronchi in case of a cold, when a person has a cough and sneeze.
