  1. Yeah, I’m one of those. I also sneeze when there is a sudden change in temperature or when the air suddenly gets moist. Dishwashing always brings on a few good ones. I’m glad to hear that it’s because I am ‘more sensitive’ than the rest of you lot.

  2. It happens to me only when I look up at a bright sunny sky, and then only once. As soon as I’ve got one sneeze out of the way, I’m okay. Interesting to read this because I’ve often wandered what kind of allergy may cause a person to sneeze when looking at the Sun, or what kind of evolutionary benefit (if any) there may be.
