Question:
Why is it when look at the sun ti helps you sneeze?
Answers:
This is called the photic sneeze reflex, or simply ACHOO syndrome. Surprisingly, its genetically determined (Autosomal Dominant), so one of your parents must have it. Its caused by a mutation in some of the nerves connected to the eye and the brain, which trigger a sneezing response. Really odd, just one of the many quirks of the human body. I guess almost 25% of people have it and its especially prevalent in caucasian populations. I don't have it, but I bet its pretty cool! Hope that helped
