Question

Why do we often sneeze when we inhale dust air

Answer 1

Answer:

hello , here is your answer

By sneezing, our body tries to expel the dust particles from the air we inhaled so that only clean air enters our body.

Answer 2

Answer:

Our nostrils are lined with fine hair and mucus membranes to protect the nasal cavity. When we inhale dusty air, the particles of dust irritate the mucus membranes and get trapped in the hairs. This irritation causes us to sneeze as a reflex, in order to expel the foreign particles, i.e. dust, from our nose. Sneezing is one way by which our body prevents the invasion of  dust and bacteria inside our lungs.
