How fast do you think you can throw a ball? Well, a sneeze is about as fast as a professional baseball pitcher can throw a fastball. The most conservative estimates I found were 150 km per hour or roughly 100 mph. The highest estimate I found came from the JFK Health World Museum in Barrington Illinois who claim that a sneeze can go as fast as 85% of the speed of sound or approximately 630 miles per hour. This sounds like an unusually high estimate and the most likely speed is probably 150km/hr. Once in awhile, in science, we can have conflicting answers. It is the job of the responsible scientist to decide which information is most likely correct. The reason why sneezes are so powerful is because not just the nose is involved. It is a reflex response that involves the muscles of the face, throat, and chest. Have you ever noticed that you have to close your eyes when you sneeze?
