I have the photic sneeze reflex so I sneeze when I look at bright light.
Check out 23andMe: ve42.co/23andme
*So technically the single nucleotide swap (C instead of T) is not actually in a gene per se but in an intergenic region on chromosome 2. It's also not clear exactly how this affects physiology or causes the sun sneeze but there is correlative evidence that every copy of this single nucleotide polymorphism (SNP) is associated with a 1.3x increase in likelihood of having the photic sneeze reflex.
I have wanted to make a video about sun-sneezing for a long time. It is something I've experienced my whole life. When I go from a dark room indoors into full sunlight I invariably sneeze. I thought everyone did it. So my original question was why do people sneeze when they see bright light? That led me to consider what possible evolutionary advantages there could be to sneezing in sunlight. The obvious advantage to me is that sunlight kills pathogens of which there may be many in your snot or mucus. So sneezing in sunshine is a much better idea than sneezing inside a dark, damp cave where you may be living.

My girlfriend makes fun of me because I always look up at lights when I'm trying to sneeze. Thank you for proving that it's genetics and NOT something I conditioned myself to do! I knew light helped me sneeze. I wasn't bullshitting, Amy!

You may find that wearing sunglasses can prevent you from photic sneezing. I noticed in your picture that the other three people in the picture were wearing sunglasses and you were not. Give it a shot.

Serious question I have to take physicals every year at my job, I have 20 10 vision . apparently really good eye sight. I am also a person out of 7 kids who doesn't have this bright light sneeze symptom and I thought I was just crazy that no one had this sneeze thing. all of my family siblings and parents need glasses before my age now and I have good vision vision but they don't have the sun sneeze I do. Anyone else the same as me? Do we just have sensitive eyes then?

The physics behind this is clear and he does not have a clue! The sun heating the surface causes hot air to rise lifting particles into the air, when these particles enter your nasal cavity is, what causes you to sneeze. PERIOD!

Looks like I also have this gene, but for me not only the sun helps me to sneeze, but any bright light. But what's even stranger is that sometimes it is enought to just touch the light switch and it helps me to sneeze, even when no light is turned on 🤔

Derek photic sneeze reflex is autosomal-dominant so yea everybody will have it soon if not now.The growing population is a point but each of the people with it will have children with it, so it might increase or stay the same , therefore at a point everyone will have it.Well everyone with it may die (but it would a large coincidence).Some people with it may die so yea in this way it might decrease just by a little . So does anyone else want it like me.give me your reply's here

I'm definitely a sun-sneezer. I first noticed this when I was in high school that every time at the end of the day when I would exit the building to get on the bus I would sneeze instantly, thought it was the strangest thing (and annoying).

I'm a sun sneezer. I'm pretty sure it's mostly light based but the heat does help too sometimes. Particularly if I transition from a cold and dark room to the sunny and warm/hot outdoors I will immediately sneeze usually more than once if the change is more drastic. It also depends on how long I was in the cold/dark room as well.

When I was really young I asked my mom why I sneezed when I looked up in the sky and she said it was because of the dust in the air. Then I saw this video and realised that I have the privilege to never lose a sneeze because all I'd have to do is look at a bright light. :p
