Answer:
It's because you are breathing in dust particles, and sand particles that will make it harder to breath.
Explanation:
"Sandstorms contain sand and dust particles and when you're in one you will be breathing in those sand and dust particles" which is putting the particles in your nostrils and lungs which will make it harder to breath. The consequences of breathing in these particles will strengthen if you already have problems with breathing.
