Ah….ah….ah…. ACHOO (autosomal-dominant compulsive helio-ophthalmic outbursts of sneezing)!!!!

Check out this Scientific American article on the photic sneeze reflex (PSR) or the ACHOO syndrome, which describes sneezing that occurs in response to bright light. Apparently this type of sneeze reflex has a genetic component, and occurs in 18-35% of the population. Though I can’t answer James’ question (“why does it feel good to sneeze?”), maybe it’s good enough to suggest that if you can’t get that lurking sneeze out, try looking at a bright light. But don’t look directly into the sun…
