Does dust make you sneeze?

Chalk dust can make people sneeze for the same reason regular dust does. What happens is when you breathe in dust, the tiny particles of it get stuck to the mucus coating the inside of your nose. If there's enough dust, it can irritate the mucous membranes inside your nose. When the membrane's irritated, you suddenly feel an intense tickle inside your nose, which triggers your sneeze reflex. When you sneeze, air is forcefully blasted out of your mouth and nose, helping to get rid of what was that made you sneeze.

What is dust made out of?

Dust includes miscroscopic particles from the air that settles on objects or areas inside or outside. Outside, it can contain particles of earth, pulverized stone that turned to dust, remnants of garbage or debris, broken down particles from leaves and plants, plant pollens, and chemicals used on lawns or industries. Interestingly, "dust" from volcanic eruption can be carried around the world and affect people in other countries. Inside, dust can contain air particles, lint from clothing, dead skin cells, dandruff from people, dander from pets and their dead skin cells, fur and human hair, and anything brought in from the outside. Dust mites are also in dust, where dust mites feed on people and pet's dead skin cells.
