How does sneezing work? The principle of sneezing

A sneeze usually refers to an allergic nose or an itchy sensation that penetrates deep into the outer tract and is released involuntarily. Sneezing can be a symptom in its own right, and sometimes accompanied by other symptoms such as itching, runny nose, nasal congestion, or itchy, watery eyes, and tearful breathing – every cold symptom is present.
