Now that you know why the sun makes people sneeze check out this video and find out What Determines “Partly Cloudy” vs. “Mostly Sunny”? (And Other Weather Terms Explained): ua-cam.com/video/TGeGVd7J6dQ/v-deo.html
Im curious why many people such as news reporters, politicians and yourself open one side of the mouth more than the othe other when they talk. It does look like yall are stroke victims
I didn't realise that not everyone experienced this until I was in my twenties. Someone at work said, "I want to sneeze, but I can't." I responded, "Well, just look at a light!" My co-worker apparently thought this was a strange thing to say, so that made me realise that not everyone has this reaction
Zappa Woman someone said that to me in middle school, it was the first time for me and pre Google. So I asked what the hell she meant. I knew a few kids who would sneeze like this.
Same for me. My entire family does it, so I never knew different until I got married. People still look at me like Im crazy when I tell them why I'm sneezing
Today I not only found out why some sneeze while getting struck by sunlight, but also how to handle sponsorship properly. I am in full support of this format
The format you have with the sponsors here is a good one, I approve. And, with the bonus facts, you even gave an incentive to stick around until the end. I approve
Victims? I love sneezing. It feels great. I am one of the 29% of people who sun sneeze. If I see a bright light and it's making me feel like I'm going to sneeze, I look at it on purpose 'cause I love it.
I recognized that I experienced this when I was 11 or 12. I mentioned it to someone and was mocked! Thank you for confirming this correlation between sunlight and sneezing.
I’m one of those solar sneezers. In addition, when I sneeze normally, I typically sneeze three times in a row. My solar sneezing theory was always that my vision and senses were overwhelmed by bright sunlight and my brain interpreted it the same way it would if my nostrils were overwhelmed by dust or other contaminate and caused me to sneeze.
I used to think it was cold, dusty air from inside, getting warmed by the sun. Since the cold air would expand and cause the dust-particles to tickle the nose... But since I'm quite sensitive to strong light, this explanation makes sense too.
This happens to me all the time. My Optometrist told me the optic nerve gets overloaded, and the signal jumps the track onto the adjacent nerve, which happens to control sneezing. I guess he was right, at least according to one theory.
Can confirm, I sneeze exactly twice when moving from a darker area to outside. My Mom also, though not sure how many times. Also wearing polarised sunglasses does indeed prevent it.
Now I just want to know why growing up I never sneezed more than once, but starting about 7 years ago I became a multi sneezer, sneezing twice, this went on for a few years and for the last few years almost every time I sneeze it's 3 in a row. 🤔
Some of the photos of people sneezing, showed them near flowering trees and plants. In those cases, sneezing would be more likely to be caused by airborne pollen.
2:19 Well, if one parent haves the phenotype for ACHOO they either have the genotype Aa or AA, and the other parent that doesn't have the phenotype would have genotype aa. If you cross Aa and aa, you'd get Aa, Aa, aa, aa (2/4, 50% chance of the phenotype) If you cross AA and aa, you'd get Aa, Aa, Aa, Aa (4/4, 100% chance of the phenotype) If you don't know which genotype the individual with the phenotype has (Aa (one ACHOO gene), or AA (two ACHOO genes)), which you don't mention in the video, you have to combine the two, if you do that you'll get a 75% chance of having the phenotype (6/8)
it is the bright light that makes me sneeze. (nothing to do with heat). My Ex used to fight with me everytime I left the building the bright sunlight would bounce off the black parking lot pavement and make me sneeze. I would say "The Sun made me sneeze" and he would call me a liar. (Most everyone in my family sneezed from the sun or bright light). Later I met another person with sun-sneezing who told me that "brown-eyed people (like my Ex) didn't sneeze at the sun, only hazel and blue eyes". I don't know if that is true, but since that time, when the subject came up I always noticed in my experience that the people who never sun-sneezed had brown eyes. My theory as to why we sun-sneeze, is that when we are first born, we see a bright light and the resulting sneeze reflex clears out the nose and results in us as newborns taking a first breath. I assumed that the genetic reflex was a trait designed to increase the chance of survival at birth. Also, when I and other sun-sneezers feel like we have to sneeze but can't, we can look at a bright light (man-made) to help us sneeze and get rid of the sensation.
Awesome video again Dave and Simon. Posted on my birthday as well and you even mentioned my home state, Alabama! Not only is it illegal to have a bear wrestling match its also illegal to put salt on railroad tracks in Alabama.
Here’s one for you, Simon - an idea for a show, of vaguely similar in nature: I used to ride a vanpool to and from work. While I did that, I had ... quite a few ... incidences, especially in the afternoon returning-home trip, where I would feel increasingly nauseous until I felt like I was about to vomit. Instead what happened, however, was that I sneezed a couple times, and the nausea went away immediately! At first I found it hard to believe that these symptoms/happenings were related, but it happened many times. I then looked it up on the Internet, and found that they are related, and it’s not just me by any means! I don’t remember the details, but it had something to do with the Vagus Nerve, as I recall...
Oh dear lord, thank you Simon! I have wondered about this for so gosh darn long now. For first half of day, starting 4 in the morning, I show no signs of being sick, and bam! I sneeze 10 straight times in 2 minutes.
Eye squinting affects muscles that twitch the nose. The unexpected movement of the nose due to the involuntary squint confuses the brain into thinking something is entering the nose. The signals are faster or slower in reaching their centers in different people.
just a few weeks earlier i watched a video where a pilot said that they cant wear polaroid sunglasses, because it dims some LCD screens. i also have to tilt my head in a car to see the time or radio station because my polaroided sunglasses work that way..
Simon, many people (okay maybe just me?!) would love to find out more about you and Daven as UA-cam personalities. Could you guys do some kind of a video like "the personalities behind the today I found out videos"? Just like, what you guys did for work before UA-cam, hobbies, spouses or children, fave movies or shows or books, etc. Idk, I just think it'd be interesting!
Thanks for the video on this. I too have it. For years I thought that it was something in the air, until I went to work at the family Millwork business. I often worked just inside a large garage door, open next to a busy street. So when I went out to go to lunch I would have to stand there and get my sneezes over with before I could attempt to cross the street. I knew it could not be allergies, same air, just inside the building, so when I heard of this it was an "ah ha" moment, but did not know it was genetic...
I've been bothering with constant flu for a few years now. There's no 14 days in which my nose doesn't run for at least 2 days. I also don't appreciate sunsets too, as they make me bored and tired. Lately (for about a year now) I've also been having dizzy sight, as it hurts to look at anything, and everything around doesn't look clear. It lasts for about 10 minutes and after that i get a headache.
This has something to do with looking up. When I look in to the bright light of the camera flash of my phone I can feel a tingle, the sneeze will follow when I hold it up and look in to it. Or when there already is the urge for a sneeze because of dust, looking up in to a bright light will cause a sneeze much faster than looking down in to a bright light.
The nerve stimulation sounds pretty much bang on for me - in my case, bright sunlight will create a ticklish sensation within the bridge of my nose and this persists even though sneezes after the first are rare for me for about an hour.
I have it but for me it can be triggered by staring into any sufficiently bright light source. I don't find it unpleasant or irritating as it's easy to control (look away from the light). I usually (but not always) have to stare at the light for a few seconds to make the sneeze actually happen, otherwise it's just a tingly sensation in my nose like you get when your nose is irritated but not to the point you actually sneeze. The only light bright enough that I don't have to look directly at it to get the response is the sun. Everything else requires a direct line of sight.
I often have sneezing episodes (maybe up to ten times) which don't have anything to do with the sun or light levels. I can sort-of understand this trigger, though. Scaring someone to stop hiccups kind-of works, but you usually end up scaring nearby people worse.
Pilots usually arent allowed to wear polarised sun glasses as they can make cockpit displays disappear at certain angles. I have this gene and also happen to do that job. The only issue I have is when ever I do my walk around on a bright day and look upwards to check the propeller blades for damage I end up sneezing on them. I'm sure and residue is sufficiently dispersed when we start the engines.
I have been a victim of ACHOO, doesn't happen al of the time but often when I go outside on a sunny day after being cooked up at work for 8 or so hours.
I have this too, as did my father. Usually get two to three sneezes out of it. I don't know about anyone else, but even if manage to hold back the sneeze when looking at bright light, it ALWAYS makes my eyebrows hurt.
This does happen to me, but not all the time, and I usually only sneeze once. My brother on the other hand will sneeze 3 to 5 times pretty much every time he is exposed to sunlight after being in a dark environment. I find it fascinating how it affects only some people and to different degrees in that specific group.
Oh goody. I always wondered about this and Derek (veritasium) made a video about it a while back as well. I don't remember exactly but i think he said sun sneezing is genetic and It's Okay To Be Smart didn't agree with him. So, they had a discussion about it as well :3
I can easily see how it would be an evolutionary advantage to have a mechanism that stops stupid simians from looking at the sun for too long. I would be willing to wager that it was more prevalent in the distant past than today. I'm not sure how you could even test for that, though, short of cloning new humans from ancient DNA in order to study their responses. :/
FYI: I haven’t watched the video yet. But, I was taught in my anatomy and physiology class that it’s because of your cranial nerves. The olfactory (smell) and optic (sight) nerves lie next to each other at a certain spot within your head. So when you look at bright light, the nerve is stimulated and stimulates it’s neighbor while the impulse travels along the nerve.
I have this and so does my mother. Even ceiling lights affect me. I developed epilepsy at 15 and became photosensitive at 18. I now have an extreme type of photosensitive epilepsy. Fml.
I get a runny nose or itch in my nose based on sudden changes in temperature. Like going from an air conditioned room and walking outside where its 15 degrees warmer. I theorize it's because the mucus or water in my nose is shifting based on the change in pressure/heat and causing the hairs inside the nose to react. But this wouldn't really account for the 'solar sneezing' described in this video, which I don't think I have. The idea that your eyes reacting to sunlight might generate a itch in your nasal cavity sounds like it could be a good candidate to me.
I have this condition and always felt that it was a crisscross of nerves. The funny thing is, as I've gotten older, this conditions seems to have lessen. I sneeze less frequently but still feel like my nose is irritated. I hypothesize that this is either 1) a decrease in eyesight ability thus lessening the "intensity" of the nerve receptor response; or 2) increased separation distance of the two nerves, again decreasing the intensity. I do have a young child so will be curious to see if they take on daddy's genetic trait :).
Solar sneezes have always fascinated me, so I found another way to combat this is to relax my soft palate. That's how I've always stifled sneezes, idk if anyone else has come to this conclusion. If you have, let me know!
I had this as a child and seems to have disappeared. I used to think it happened because of similiarities in facial muscle movements in squinting as there is in sneezing.
I recall a HS classmate asking about that in class. Nobody knew what he was talking about. Since then, it has happened to me 2-3 times, that I am aware of.
I sneeze when I look directly at the daytime sky as well though. Often 3-5 times. Sometimes I even sneeze once or twice at a particularly bright artifical light.
I have ACHOO so this was really interesting.... BTW, I love how we think of scientists as boring nerds with no sense of humor, yet they create acronyms as "achoo"
I sneeze once. I haven't asked my sisters or parents about the photic sneeze, but I should. Then again, I have the condition of visual snow and whatnot and my sisters don't. Also, mints make me sneeze, particularly peppermint ones. Not the candy swirl type, but the strong mints like Icebreakers or Altoids.
I have sun sneezes and it’s really not helpful when trying to cross the street or something like that. But other than that I kinda like it, cause when I have the need to sneeze but I can’t, I just look into light or the sun and I usually can. 👍🏻
I have this and thought it had to do with my being allergic to hyperexposure to the sun. In other words I already have allergies to long time to sun even when in the shade or cloud days. I just don't get sunburn but breakout and my eyes get burned.
I have this solar sneeze syndrome, my parents don't. But then I've got a weird version: it doesn't come on as soon as I'm out in the sun, it takes a couple of minutes. Also, I never had it before I first heard of it (30+ years ago).
But I feel that you could also condition yourself to do this. I read that study in early 2015 and I performed my own self experiment. Every time I had to sneeze I would look at the sun or a bright light. After doing this for about 2 months I could look at the sun or a bright light and it would trigger a sneeze. This became a bit tedious so I stopped looking at bright lights during sneezes and the conditioning was reversed.
For me, it's not just bright light. Just as often, it's triggered by dimming or brightening light. The onset of the eclipse set me off ( sun behind me. Just walking outside ) Similar things will happen at sunrise, sunset, and incoming weather. Fluorescent lights that haven't completely warmed up or are dying trigger it.
I don't sneeze from light. However, as a trick to fall asleep at night, I'll often visualize a story scenario to occupy my mind, which will then shift into dreaming if I successfully fall asleep. Whenever I reach a certain level of vividness with my imagination, I sneeze twice. It's rather annoying actually. I've always felt a similar mechanism was at play - just that it was a different stimulus; so, I believe the first explanation is correct. If your brain could reliably tell the difference between real vs imagined visual input, we wouldn't call it REM.
It seems to happen to me whenever I'm at a campfire and the person in front of me decides to move, but I generally get the urge to rub my face and eyes, more often than sneeze.
It doesn't need to be a dark room for me, I sun-sneeze almost every time I leave a building, even if it's overcast! (Though more commonly when it's sunny, and never at night) My father has this as well, both 1 sneezers! (With the rare 2 thrown in!) For me the sensation is; as I step into the outdoors, I squint, and my nose suddenly feels irritated, which builds up, and causes me to sneeze in about 5 seconds.
Always thought there was a crossed wire in the central nervous system that caused it. Something acupuncturists would most likely agree to. Strangely enough, a scientist has established a link between our vision and our taste buds. Saw a mind-blowing report years ago where a scientist placed a device on the tongue of a blind patient and he was able to navigate around a room with obstacles. The reporter was able to do likewise once blindfolded. This seemingly unrelated connectivity of our nervous system may have totally unexpected benefits. ...and now for a bonus comment: Does Whistler’s Mother know what her son does for a living? That stern painting of hers would seem to indicate that she disapproves.
one problem, pilots are NOT ALLOWED to wear polarized sunglasses. i quote,"Polarized lenses are not recommended for use in the aviation environment. While useful for blocking reflected light from horizontal surfaces such as water or snow, polarization can reduce or eliminate the visibility of instruments that incorporate anti-glare filters. Polarized lenses may also interfere with visibility through an aircraft windscreen by enhancing striations in laminated materials and mask the sparkle of light that reflects off shiny surfaces such as another aircraft’s wing or windscreen, which can reduce the time a pilot has to react in a “see-and-avoid” traffic situation"from ( www.faa.gov/pilots/safety/pilotsafetybrochures/media/sunglasses.pdf )
Outstanding job on the ad at the end of the vid!!!! That kept me watching, interested, and entertained. Your team is awesome at that!!! If I feel the need to hide my suspicious browsing habits I will check out Tunnel Bear. Growl....
Todd Dougherty It is actually very useful especially if you use WiFi hotspots as it keeps your phone data safe from any WiFi scanners. For me it also means I can watch videos from places that are region or country locked.
I do this and wasn’t sure why I didn’t know anyone else who did. At least now I know more about it. Though nobody else in my family does it. Should I be worried?
It isn't just the sun, any bright light can make me sneeze including my phone. It makes me nervous when driving. I can sneeze when it is cluoudy and foggy. I can also sneeze from the reflection of the sun off of cars. My father sneezes but he is not as sensitive as I am. I am the most sensitive out of my family with my son second.
Dr. Derek "Veritasium" Muller has this trait and also recorded a video on sneezing at the Sun. I wonder if Bacon really had such a strabismus. Cute, maybe unintential, pun, "shed a little more light on..." No, wait..."...turned to a lighter note..."
I'm pretty sure it's the last theory of the guy who did brain scans- that the nerves are close together. If you need to sneeze, and try looking at a light to force it, it will only work for the first few seconds- to me this implys that once the iris is contracted, the signal is lessened and then the need to sneeze gone
I feel a sneeze coming on and look at a light source and that triggers my sneezes. Min 4....max seven. Every second dayish. I don't need the light....It just expedites the process and ensures it happens.
I always thought maybe it's because the brightness of the sun makes your face contort a bit from squinting and better facilitating the sneeze initiation program.
I think it depends on the cause of the blindness. Some blind people, for example, can kind of see based on a 'sense' of where or what things are. They get no direct visual input to their conscious brain, but the problem that is causing this is past the part where the visual signals interact with the deeper and more unconscious regions of the brain, allowing the brain to receive some information, enough to tell some things apart and navigate some course, but not the whole picture that we call vision. I would assume this person would sneeze at the sun, where they predisposed for the condition.
GreatValueTv Asssuming this specific trigger also gets triggered by sudden bright lights it can be assumed you need a visual impulse. As a person that has absolutely no eyesight they wouldn't be affected by this.

just watch this...
My friend always sneeze when he look on the bright light, especially sun.
That seems so damn weird as for me :/
It’s not just the sun. Looking at the light on the ceiling also gets me finally sneeze when I’m about to but I can’t.
Exactly that is what happens to me
It's a great life hack! Once I figured that out no more waiting around for a sneeze. If I feel a sneeze coming... look at ceiling light. Achoo. Done!
thanksfer.....n..what ever. yes, but you might go blind
thanksfernuthin
It's not a bug; it's a feature!
Mr. Herpes. I didn't say I stare at ceiling lights. I look at them for less than a second, you knuckle head.
3 sneezes every time without fail. I kind of enjoy it tbh
Because *the sun is a deadly lazer*

I suggested this question about a month ago. Thanks for anweing so fast. Love this channel.
This is one of the best videos you guys have ever done.
“Solar sneeze” makes it sound like some kind of awesome power.
Now I just want to know why growing up I never sneezed more than once, but starting about 7 years ago I became a multi sneezer, sneezing twice, this went on for a few years and for the last few years almost every time I sneeze it's 3 in a row.
🤔
Finally!! An answer to why this happens to me with ANY bright light! Thank you!
Some of the photos of people sneezing, showed them near flowering trees and plants. In those cases, sneezing would be more likely to be caused by airborne pollen.
2:19 Well, if one parent haves the phenotype for ACHOO they either have the genotype Aa or AA, and the other parent that doesn't have the phenotype would have genotype aa.
If you cross Aa and aa, you'd get
Aa, Aa, aa, aa (2/4, 50% chance of the phenotype)
If you cross AA and aa, you'd get
Aa, Aa, Aa, Aa (4/4, 100% chance of the phenotype)
If you don't know which genotype the individual with the phenotype has (Aa (one ACHOO gene), or AA (two ACHOO genes)), which you don't mention in the video, you have to combine the two, if you do that you'll get a 75% chance of having the phenotype (6/8)

kalaya01 Whole family has brown eyes, me and my sisters sneeze at bright light.
I have always thought of it as a defence mechanism.
Bright light, could damage your eyes.
When you sneeze, you close them.
robo336
I'd be an odd defense mechanism. Confronted by a predator I'd be at risk if sneezing reduced my ability to defend myself.
If that predator happens to glow as bright as the sun, perhaps you should still be worried about defending your eyesight.
I have wanted to know the answer to this question for over 20 years. Finally! Thank you!
Great idea with the bonus facts and the ad.
Awesome video again Dave and Simon. Posted on my birthday as well and you even mentioned my home state, Alabama! Not only is it illegal to have a bear wrestling match its also illegal to put salt on railroad tracks in Alabama.

Oh dear lord, thank you Simon!

Idk why but I feel so relieved when I sneeze
Eye squinting affects muscles that twitch the nose. The unexpected movement of the nose due to the involuntary squint confuses the brain into thinking something is entering the nose. The signals are faster or slower in reaching their centers in different people.
When I told my coworkers to look at the light when they are about to sneeze they think I am a Weirdo.
just a few weeks earlier i watched a video where a pilot said that they cant wear polaroid sunglasses, because it dims some LCD screens. i also have to tilt my head in a car to see the time or radio station because my polaroided sunglasses work that way..

Thanks for the video on this. I too have it. For years I thought that it was something in the air, until I went to work at the family Millwork business.

The only issue I have is when ever I do my walk around on a bright day and look upwards to check the propeller blades for damage I end up sneezing on them. I'm sure and residue is sufficiently dispersed when we start the engines.
I have been a victim of ACHOO, doesn't happen al of the time but often when I go outside on a sunny day after being cooked up at work for 8 or so hours.
I have this too, as did my father. Usually get two to three sneezes out of it. I don't know about anyone else, but even if manage to hold back the sneeze when looking at bright light, it ALWAYS makes my eyebrows hurt.
Thank you Simon. I finally now know why this happens to me
When I was little I thought it was normal and everyone had it
This does happen to me, but not all the time, and I usually only sneeze once. My brother on the other hand will sneeze 3 to 5 times pretty much every time he is exposed to sunlight after being in a dark environment. I find it fascinating how it affects only some people and to different degrees in that specific group.
Oh goody. I always wondered about this and Derek (veritasium) made a video about it a while back as well. I don't remember exactly but i think he said sun sneezing is genetic and It's Okay To Be Smart didn't agree with him. So, they had a discussion about it as well :3
Pluto : very original! 😁
I can easily see how it would be an evolutionary advantage to have a mechanism that stops stupid simians from looking at the sun for too long. I would be willing to wager that it was more prevalent in the distant past than today. I'm not sure how you could even test for that, though, short of cloning new humans from ancient DNA in order to study their responses. :/
Probably an adaptation for cave dwelling ancestors, to clear their nasal passages once they came back above ground.
FYI: I haven’t watched the video yet. But, I was taught in my anatomy and physiology class that it’s because of your cranial nerves. The olfactory (smell) and optic (sight) nerves lie next to each other at a certain spot within your head. So when you look at bright light, the nerve is stimulated and stimulates it’s neighbor while the impulse travels along the nerve.
I have this and so does my mother. Even ceiling lights affect me. I developed epilepsy at 15 and became photosensitive at 18. I now have an extreme type of photosensitive epilepsy. Fml.
I get a runny nose or itch in my nose based on sudden changes in temperature. Like going from an air conditioned room and walking outside where its 15 degrees warmer. I theorize it's because the mucus or water in my nose is shifting based on the change in pressure/heat and causing the hairs inside the nose to react. But this wouldn't really account for the 'solar sneezing' described in this video, which I don't think I have.
The idea that your eyes reacting to sunlight might generate a itch in your nasal cavity sounds like it could be a good candidate to me.
I have this condition and always felt that it was a crisscross of nerves. The funny thing is, as I've gotten older, this conditions seems to have lessen. I sneeze less frequently but still feel like my nose is irritated. I hypothesize that this is either 1) a decrease in eyesight ability thus lessening the "intensity" of the nerve receptor response; or 2) increased separation distance of the two nerves, again decreasing the intensity. I do have a young child so will be curious to see if they take on daddy's genetic trait :).
I love sneezing, it makes the hairs on my arms stand out and i get a tingling sensation. Also when you do it other people near you bless you.
Doreen Green while they hope it's not SARS or ebola
it's impossible to give someone a nasty disease if you sneeze like a cute squirrel
Doreen Green granted it probably won't get as far
I have never heard of this phenomenon before.
What happened to the style you tried out 5 days ago? I loved it!
Who else clicked on this because you've never heard of people sneezing from the Sun
Solar sneezes have always fascinated me, so I found another way to combat this is to relax my soft palate. That's how I've always stifled sneezes, idk if anyone else has come to this conclusion. If you have, let me know!
I had this as a child and seems to have disappeared.
I used to think it happened because of similiarities in facial muscle movements in squinting as there is in sneezing.
Thank you
I recall a HS classmate asking about that in class. Nobody knew what he was talking about. Since then, it has happened to me 2-3 times, that I am aware of.
I sneeze when I look directly at the daytime sky as well though. Often 3-5 times. Sometimes I even sneeze once or twice at a particularly bright artifical light.
I have ACHOO so this was really interesting.... BTW, I love how we think of scientists as boring nerds with no sense of humor, yet they create acronyms as "achoo"
I sneeze once. I haven't asked my sisters or parents about the photic sneeze, but I should. Then again, I have the condition of visual snow and whatnot and my sisters don't. Also, mints make me sneeze, particularly peppermint ones. Not the candy swirl type, but the strong mints like Icebreakers or Altoids.
I have sun sneezes and it’s really not helpful when trying to cross the street or something like that. But other than that I kinda like it, cause when I have the need to sneeze but I can’t, I just look into light or the sun and I usually can. 👍🏻
Where did the "my dog ate my homework" gag come from?
dog ate my glock.
Dogs eating homework. Because dogs wil chew on anything.
I have this and thought it had to do with my being allergic to hyperexposure to the sun. In other words I already have allergies to long time to sun even when in the shade or cloud days. I just don't get sunburn but breakout and my eyes get burned.
I have this solar sneeze syndrome, my parents don't. But then I've got a weird version: it doesn't come on as soon as I'm out in the sun, it takes a couple of minutes. Also, I never had it before I first heard of it (30+ years ago).
And I thought I was the only one who sneezed when I looked tward the Sun.
But I feel that you could also condition yourself to do this. I read that study in early 2015 and I performed my own self experiment. Every time I had to sneeze I would look at the sun or a bright light. After doing this for about 2 months I could look at the sun or a bright light and it would trigger a sneeze. This became a bit tedious so I stopped looking at bright lights during sneezes and the conditioning was reversed.
For me, it's not just bright light. Just as often, it's triggered by dimming or brightening light. The onset of the eclipse set me off ( sun behind me. Just walking outside ) Similar things will happen at sunrise, sunset, and incoming weather. Fluorescent lights that haven't completely warmed up or are dying trigger it.
I don't sneeze from light. However, as a trick to fall asleep at night, I'll often visualize a story scenario to occupy my mind, which will then shift into dreaming if I successfully fall asleep. Whenever I reach a certain level of vividness with my imagination, I sneeze twice. It's rather annoying actually. I've always felt a similar mechanism was at play - just that it was a different stimulus; so, I believe the first explanation is correct. If your brain could reliably tell the difference between real vs imagined visual input, we wouldn't call it REM.
It's nice to be able to say you are allergic to sunlight when your mom asks you to go outside.
It seems to happen to me whenever I'm at a campfire and the person in front of me decides to move, but I generally get the urge to rub my face and eyes, more often than sneeze.
It doesn't need to be a dark room for me, I sun-sneeze almost every time I leave a building, even if it's overcast! (Though more commonly when it's sunny, and never at night)
My father has this as well, both 1 sneezers! (With the rare 2 thrown in!)
For me the sensation is; as I step into the outdoors, I squint, and my nose suddenly feels irritated, which builds up, and causes me to sneeze in about 5 seconds.
I don't even know if I have this or not. I would test it out, but the weather isn't cooperating at the moment.
Always thought there was a crossed wire in the central nervous system that caused it. Something acupuncturists would most likely agree to. Strangely enough, a scientist has established a link between our vision and our taste buds. Saw a mind-blowing report years ago where a scientist placed a device on the tongue of a blind patient and he was able to navigate around a room with obstacles. The reporter was able to do likewise once blindfolded. This seemingly unrelated connectivity of our nervous system may have totally unexpected benefits. ...and now for a bonus comment: Does Whistler’s Mother know what her son does for a living? That stern painting of hers would seem to indicate that she disapproves.
That ad placement 👌👌
one problem, pilots are NOT ALLOWED to wear polarized sunglasses. i quote,"Polarized lenses are not recommended for use in the aviation environment. While useful for blocking reflected light from horizontal surfaces such as water or snow, polarization can reduce or eliminate the visibility of instruments that incorporate anti-glare filters. Polarized lenses may also interfere with visibility through an aircraft windscreen by enhancing striations in laminated materials and mask the sparkle of light that reflects off shiny surfaces such as another aircraft’s wing or windscreen, which can reduce the time a pilot has to react in a “see-and-avoid” traffic situation"from ( www.faa.gov/pilots/safety/pilotsafetybrochures/media/sunglasses.pdf )
THIS HAS HAPPENED TO ME SO OFTEN, FINALLY I GOT THE ANSWER! I have been thinking this since I was 3!
Outstanding job on the ad at the end of the vid!!!! That kept me watching, interested, and entertained. Your team is awesome at that!!! If I feel the need to hide my suspicious browsing habits I will check out Tunnel Bear. Growl....
Todd Dougherty It is actually very useful especially if you use WiFi hotspots as it keeps your phone data safe from any WiFi scanners. For me it also means I can watch videos from places that are region or country locked.
Todd Dougherty Agreed, this was brilliant advertising.
I do this and wasn’t sure why I didn’t know anyone else who did. At least now I know more about it.
Though nobody else in my family does it. Should I be worried?
Being in Florida, I walk out of Publix and sneeze. I bought sunglasses and put them out right as walk out the door it went away. Such a weird thing.
Has the music in the background always been there or is this a new thing?
It isn't just the sun, any bright light can make me sneeze including my phone. It makes me nervous when driving. I can sneeze when it is cluoudy and foggy. I can also sneeze from the reflection of the sun off of cars. My father sneezes but he is not as sensitive as I am. I am the most sensitive out of my family with my son second.
Dr. Derek "Veritasium" Muller has this trait and also recorded a video on sneezing at the Sun.
I wonder if Bacon really had such a strabismus.
Cute, maybe unintential, pun, "shed a little more light on..."
No, wait..."...turned to a lighter note..."
I'm pretty sure it's the last theory of the guy who did brain scans- that the nerves are close together.
If you need to sneeze, and try looking at a light to force it, it will only work for the first few seconds- to me this implys that once the iris is contracted, the signal is lessened and then the need to sneeze gone
I feel a sneeze coming on and look at a light source and that triggers my sneezes. Min 4....max seven. Every second dayish. I don't need the light....It just expedites the process and ensures it happens.
I always thought maybe it's because the brightness of the sun makes your face contort a bit from squinting and better facilitating the sneeze initiation program.
Im one of them! But it can be a any strong light!
I must not have it because I saw the title to the video and asked "Wait, the sun makes you sneeze?"
I lol'ed at "ACHOO", ha!
Does this affect blind people too?
avlisk No my dear.
Your ideas are intriguing to me and I wish to subscribe to your news letter.
I think it depends on the cause of the blindness.
Some blind people, for example, can kind of see based on a 'sense' of where or what things are. They get no direct visual input to their conscious brain, but the problem that is causing this is past the part where the visual signals interact with the deeper and more unconscious regions of the brain, allowing the brain to receive some information, enough to tell some things apart and navigate some course, but not the whole picture that we call vision.
I would assume this person would sneeze at the sun, where they predisposed for the condition.
MCgoos09/BelgianCat can you please share the report that agrees with your statement.
GreatValueTv Asssuming this specific trigger also gets triggered by sudden bright lights it can be assumed you need a visual impulse. As a person that has absolutely no eyesight they wouldn't be affected by this.
