When something enters your nose or you encounter a trigger that sets off your “sneeze center” in your brain, located in the lower brain stem, signals are rapidly sent to tightly close your throat, eyes, and mouth. Next, your chest muscles vigorously contract, and then your throat muscles quickly relax. As result, air — along with saliva and mucus — is forced out of your mouth and nose.
9. Part of the message the brain receives in the lead-up to a sneeze is to close those eyes.
