The Reason for Sneezing
The reason for sneezing is really quite clear. You breathe in some dust and blow it out in the air.
Your nose gets a tickle because of this dust. Your body rejects it. It should, and it must.
The way that you sneeze is always the same. Information is sent to your lungs from your brain.
Many muscles contract to push that sneeze through. That's your diaphragm, belly, and chest muscles, too.
Your eyes shut. Your tongue's on the roof of your mouth. This forces your nose to blow that breath out.
