【英语时差8,16】打喷嚏-上

The signs are unmistakable: the eyes water, the chest heaves, the nose twitches¹, the body tenses, suspense² builds… until finally a sneeze blasts forth³, concluding the drama. It’s a momentarily paralyzing experience that can seize one at almost any time. But try and recall if you’ve ever been jarred out of a peaceful sleep by an explosive sneeze. Chances are you can’t, because, thankfully, we don’t sneeze while we sleep. To understand why, first we need to know why we sneeze while we’re awake. Sneezing is a reflex, which means that it’s an uncontrollable physical response to an outside stimulus⁴. When something, say a piece of dust or a strong odor, stimulates⁵ nerve endings in the lining⁶ of the nose, the stimulus travels to the central nervous system and is then routed back to the muscles of the face, throat, and chest.
