Do you sneeze when something gets in your nose and irritates you?

Yes, sneezing is a natural reflex triggered by the irritation of the nasal passage. When something like dust, pollen, or other particles enters the nose and comes in contact with the sensitive nasal tissues, it causes a response known as the "nasal reflex." This reflex consists of a sudden, forceful expulsion of air through the nose and mouth, expelling the irritant and clearing the nasal passages. Sneezing is a protective mechanism that helps protect the respiratory system and maintain its hygiene by removing foreign substances.
