The Sun Sneeze Gene

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.

Well, a lot of different things affect the trigeminal nerve, and something might just de-sensitize whatever is sensitive to bright light.

[@Friddle]

Josep I'm also a double sun sneezer, I find it so annoying tho

[@GefilteFish1]

Hey Veritasium! Just a clarification- the optic nerve (cranial nerve II) is the nerve responsible for transmitting information from the retina to the visual cortex in the back of the brain. The ophthalmic nerve (first branch of the trigeminal nerve, cranial nerve 5) is a nerve that- like you said- receives sensory information from the upper face. However, these are two very different nerves- if light were to stimulate the maxillary branch, it would have to do so through the brain itself :)

[@alexjh12345]

Brody Wiles scrolled way too far to find this!

[@kassepirai5310]

Brody Wiles Brody Wiles wait doesn't the ophthalmic nerve also supply branches into the cornea, iris and the ciliary body of the eye, as well as the conjunctiva and and lacrimal gland? AND also the upper face and other parts. Although I don't really know how the light would directly affect these parts of the eye... I guess any stimulation of these parts of the eye would be indirect, like a response to bright light with the ciliary body. It is interesting that cross over has been seen between the lacrimal nerve (serving the lacrimal gland, pretty much like the tear gland, among others) and branch of the maxillary gland. But mainly I just wanted to mention the ophthalmic and the eye thing.

[@gryyphyn8639]

The predominant thinking, as I understand it, is the stimulation of the trigeminal nerve causes muscle contractions in the sinus cavity that simulate the itchy nose feeling which stimulates the nervous sneeze response. Of note is at least some people who experience photic sneezing are able to do so with lamps. I can look at a light and sneeze much of the time. It's pretty irritating, though, when I need to sneeze and can't. That's a bit painful and irritating and causes pretty severe eye watering.

[@scottdogg529]

Brody. Not necessarily... some reflexes are not processed by the brain but are affected by the spinal cord. Since the cranial nerves sit just below the brain and I don't know if they are connected to the spinal cord or directly to the brain there is a chance it is just a reflex like stepping on a tack, retracting your foot as you straighten your other leg.

[@jacobrperry]

Maybe it's the squinting?

It was depressing; food lost its lustre. I was looking at your diagram at 4:47 and realized that I've got nerve damage in my chin, so maybe that was interfering with my sense of smell since they're on the same nerve cluster? So I blocked one nostril, smelled, blocked the other, smelled again - and then it all smelled normal! Sorry for gushing. This is a big deal for me. Thank you for educating. You've made a real difference here.
