One of the symptoms of the plague was coughing and sneezing, and it is believed that Pope Gregory VII suggested saying âGod bless youâ after a person sneezed in hopes that this prayer would protect them from an otherwise certain death. The expression may have also originated from superstition.
1 The long-standing answer has been that sneezing is a reflex. 2  When irritants â such as germs, dust, pollen, animal dander, or pollutants, just to name just a few â infiltrate the nose lining, the brain sends out a signal to get rid of it.3  That triggers a deep breath, which gets held in the lungs. It has to do with sneezing being a reflex action. 2  When you're sleeping, the nerves involved in sneezing are relaxed, breaking the chain reaction of the typical sneeze. 3  If someone were to wave irritants under your nose while you were sleeping, however, you might wake up and sneeze.
