In this video:

Have you ever been in a dark place, say a movie theatre or a room with all the blinds close, and walked outside into the daylight when, all of a sudden, you begin to sneeze uncontrollably? You had no runny nose or desire to sneeze prior to this exposure to sunlight, but you just can’t help that big achoo? If you answered yes, then you are part of the twenty to thirty five percent of the human population that are “victims” of this not highly understood phenomenon, known as the “photic sneeze reflex” or a “solar sneeze.” Why do certain people have solar sneezes? How does it work? Only in the past few years have scientists begun to understand this rather odd trait.
