. Why do we often sneeze when we inhale a lot of dust-laden air

Best Answer

When we inhale a lot of dust laden air often these particles get trapped in the hair present in the nasal cavity. Then they irritate the lining of the cavity, as a result of which we sneeze. Sneezing expels these foreign particles from the inhaled air and a dust-free, clean air enters our body.
