Sneezing Helps Keep Your Body Safe
Sneezing is an important part of the immune process, helping to keep us healthy and sniffle-free. Sneezes protect your body by clearing the nose of bacteria and viruses. 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. Voila, you’ve sneezed.
