Since birth, my son has been sensitive to bright sunlight. He reacts by sneezing. My doctor has never heard of this.
Most people know of at least one person who sneezes when they are suddenly exposed to bright light.
This is most often seen when a person walks into the sunlight after having been inside for a while. Well, there is, in fact, a connection between bright light and sneezing. Now, you have to know the scientists who gave it such a label must have worked hard to come up with one that was so cute. This sneeze reflex is inherited and thought to be prevalent in approximately 24 percent of the population. The cause of it is still unknown but there are a few theories.
