Question

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

Answer 1

Sneezing:

1. A strong, involuntary ejection of air occurs during a sneeze.
2. Sneezing frequently occurs abruptly and without notice.
3. Sneezing is often referred to as sternutation.

Explanation:

1. Sneezing preserves excellent air quality within our bodies by removing foreign particles from the air we breathe, such as dust and smoke.
2. These particles irritate the nasal cavity's lining after passing through the hair there, sending a signal to the brain. The nasal cavity receives instructions from the brain to start sneezing.
3. This is a technique for clearing the nose of unwelcome dust particles.
4. Our body uses sneezing as a form of protective mechanism.
5. But occasionally, dirt and debris might get inside your nose and irritate your throat's and nose's delicate mucous membranes.
6. These membranes itch when they are inflamed.
