when we sneeze close your eyes?

'It is unclear, but scientists theorize that we close our eyes when we sneeze to protect them. We may be protecting our eyes from microorganisms and particles from our sneezes," But it could also be simply because a sneeze is a kind of bodywide reflex in which a lot of muscles contract, not just in the nose and throat but also those in the diaphragm, the abdomen, thighs, back, even sphincters (which is why some people with stress incontinence may urinate slightly when they sneeze).\n\nResearchers aren't sure exactly why the sneeze reflex happens, but whatever neurological message tells the eyes to close probably comes from a primitive part of the brain called the medulla oblongata in the brain stem.  And, it's not just an irritation in the nose that can trigger a sneeze; some people, probably because of genetics, have a photic reflex, which makes them sneeze in response to sudden, bright light.\n\nAnd, in case you were wondering about that old wives' tale about the heart skipping a beat when you sneeze, rest assured: It doesn't, though it may pause for a fraction of a second before resuming its normal rhythm.  That pause is believed to occur due to a change in intra-thoracic pressure, or pressure in the chest, when you sneeze. That pressure may stimulate the vagus nerve, which in turn slows the heart rate down for a brief moment.\n\nThis is not dangerous.   But it's believed that people began saying ''God bless you" when a person sneezes because they believed that, in that brief moment, you were between heaven and hell, and, if you were blessed, you'd be saved from damnation.

"Odaijini" (take care of yourself), if anything at all.  We don't have a custom of saying something to someone who have just sneezed.  The phrase is commonly used for someone who's ill (one assumes that if someone sneezes, that person is catching cold).\n\nThere is a popular belief, though, that if you sneeze, someone somewhere is talking about you.

It is an involuntary reaction.  I wonder if it is to keep our eyes from popping out!  But, really, that's just how our brain directs our bodies during such a complex human action.  Do animals close their eyes when they sneeze too?

Yes... But you will not knowing that you have sneeze

Well the fact is that humans cannot sneeze while asleep.\nSneezing requires a reflex mechanism, wherein the sensory nerves in our upper respiratory tract, esp nostrils, are stimulated by some stimuli (mechanical or chemical or other)and these nerves then go to the CNS (i.e brain) and as a final process excite the nerves which supply muscles pf our respiration and the pharngeal region and the man sneezes thus. You must \nknow that this reflex is a natural means to protect our sensitive upper respiratory tract from harmful influnces or, more appropriately, external influences, be it a solid or a gas or as a response to some infection. Now when the man sleeps, his brain is not working at its normal levels and so even though the man's nerves have some external factor acting upon them,\nno reflex is initiated and the man doesn't sneeze. You must also know that when the stimuli continues or crosses a particular \nlevel, it changes from an irritative agent to a source of maybe say pain and the the man can have a disturbed sleep; there is a threshold for every thing.

A sneeze happens with tremendous speed and pressure, and you can feel it coming, if a ball is coming at you extremely fast, or anything for that matter, it's our instinctive response to close our eyes. I was in a car accident and as soon as the car went off the road, I closed my eyes, there was nothing else to do. We're just people.

No. What are doing right before you sneeze? Taking in short breaths of air before finally sneezing.

It's called Photic sneezing, and it's not too uncommon. There's thought that the change in lighting that triggers the changes in your eyes (your retina getting smaller in bright light) for some reason sends a signal to your sneezing reflex as well.

A sneeze is the fastest known action that a human can perform.  It is involuntary and can make the head mover VERY sharply.  Maybe our eyes close so that we don't get anything in them when our head jerks forward?  Dust, leaves, branches, etc. would be both painful and dangerous if they got into our eyes while we were moving our head at high speed.\n\nAccording to Wikipedea:\nIt is almost impossible for a person to keep their eyelids open during a sneeze, although some rare individuals report having little if any trouble doing so. The reflex of shutting the eyes serves no obvious purpose: the nerves serving the eyes and the nose are closely related, and stimuli to the one often trigger some response in the other.

You sneeze because you have something in your nose and your body is trying to get it out.  You don't get it out the first time, or your nose is still irritated.

Sorry, we don’t know why most people close their eyes when sneezing. Not all do. \n\nSome experts guess that we’ve evolved closing eyes to reduce sneeze spray landing in our eyes. However, our eyes are exposed constantly to bacteria and viruses and have good defenses without eye closing.\n\nClosing eyes (or keeping them open) is part of the sneeze reflex. It’s a reflex—meaning we have no conscious control of sneezes. Instead, the primitive part of the brain (called the medulla oblongata and located at the top of the spine) calls the shots. The reflex triggers major muscles of face, throat, and chest to fire out gunk going at 100 mph (150 kph) as fast as a pitcher’s fastball.\n\nMost people tighten the eye muscles, causing them to shut, as they tighten the other muscles involved in a sneeze. But not all do. Some sneeze with their eyes open. Either way, it’s part of the inborn sneeze reflex.\n\nIn 1888, Thomas Edison hit upon the idea of movies from looking at sequential pictures of someone sneezing

Sneezing is actually a reflex action to a stimuli.The nerves send the message to the brain and then you sneeze. During sleep the reflex part of your brain rests too. The irritant still annoys the nerves but  no message is sent to the brain. However if the stimuli builds the irritant to  a level registered as pain the brain will wake you and you will sneeze (but to have this part of your brain working  you need to be awake!!)Scientific Fact! :)

You sneeze with your eyes open.

Your eyes are forced shuh by a part of the brain that refuses to look at the booger bits that go flying out when you sneeze.\n\nYou have overcome it looking at stuff like go-at-se until that part of the brain just gives up.

Mechanism of sneezing - Normally, sneezing is an involuntary reflex, which is controlled by a complex interaction of nerve fibres. A variety of receptor sites, situated in the nose, reports about the irritation or foreign substance to the brain for inducing sneezing by releasing histamine, for clearing the nose. Receptors are sensitive to infection, touch, smells of dust, chemical gases, fumes, temperature and exposure to extreme cold air and water (the main offender). Usually, sneeze begins with a deep inspiration and closed glottis, which suddenly opens after gaining pressure from contraction of the diaphragm, abdomen muscles and other muscles which compress the lungs to let out the trapped air with force through nose and mouth. So with an explosive sound, throw of air occurs as a sneeze. Sneezing also involves contraction of the muscles of face, neck and eyes. Sometimes, sneezing air speed is measured more than 120 km/per hour. Normally, people sneeze once or twice during early morning or daytime to clear the nose.\n\nFor more info, go to the source...

Closing your eyes is a natural reaction for several reasons: strong wind blasts and, of course, sneezing. It's mainly to keep your eyes protected from the resulting dust and mist. Your eyes will not pop out of your head, your actual sockets would hold them in! This is a myth. I don't know how it got started, but it's not true.

Heck if i know. I'm asleep. Seriously though. There's no reason whatsoever why a person can't sneeze while asleep. What if you're dreaming about petting a cat and you're allergic to cats? Yes is your answer.\n-\nOk, I read a few articles on sneezing while asleep. They all say a person can't. I still say just because people don't sneeze while asleep doesn't mean they "can't". Tell you what. Let me put some pepper under your nose while you're asleep and let see if you don't sneeze. =)\n.\n.
