Why can't we sneeze in our sleep?

I have never knowingly sneezed in my sleep, but my cat has. The end result is that it woke her up.

Because the pressure of the sneeze, you close your eyes. You can't control them because its something the body controls. Try holding your nose or biting your tongue though if you're about to sneeze. Then you don't.

'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.

due to the sudden jerk you get while you sneeze, you automatically make you body tight and then suddenly it becomes loose. thus the blood pressure increases. \nSometimes people feely giddy due to a sudden and big sneeze. this is because, the brain cannot coincide with the blood pressure. thus it happens. but remember this is all just for quite a fraction of a second. \n\nHope it was clear enough.

It's probably dust. You can clean all you want but dust is still in the air. When you clean your house you are cleaning the dust that has fallen out of the air and landed on furniture. You can't clean your air unless you have a special filter.\n\nDo you have any animals in the house? It could be an allergy to an animal.\n\nDoes it only happen in your house, or other indoor places?\n\nAs far as sneezing fits, that's how it effects some people. There isn't much you can do about it.

No it doesn't kill brain cells. Sneezing is an automatic reaction to an irritation of the nasal passages. You should never suppress a sneeze. It can cause major ear problems, eye problems and does your vascular system no good at all.\nAs an example of how strong a sneeze is, I fractured my eye socket when sneezing and it wasnt a suppressed sneeze. I couldn't believe it. My socket was fractured and the tear duct popped out of the corner of my eye!

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

Similar to the reflex that occurs when your knee kicks after it's hit with a medical hammer, or the way your hand pulls away from something hot when you burn it, closing your eyes when you sneeze is a powerful reflex.\n\nA 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). When we sneeze, we tense some of our muscles. The tensing (tightening) of our muscles causes our eyes to shut.

It is not the sun that is stopping you from the sneeze, it is the position of your head. you can look at the moon or a a piece of key lime pie that is floating in the sky and have the same result.

Yes it is healthy to sneeze! If you hold your sneezes in then you will totally mess up your sinus cavity, and have to have a $14,000+ sinus surgery. The thing about all of your functions is only if you sneeze so many time in a row. I was told if you continue to sneeze more than 12 times your heart will stop. \n\nSo, if you gotta sneeze let it out! My husband and I spent 4 sleepless nights after his surgery!

Sounds like morning allergies. I used to have that when i lived in an apt that had bad ventillation and carpet. You have to vacuum frequently, wipe away dusty areas, open your windows in the morning. When i moved into my new apt that has wooden floors, I never had the sneezing problem again.

Why would you want to?\nYou would be better off sneezing into a hanky than to attempt to stop yourself from sneezing.

It really serves no purpose - however, it seems that the nerves to the nose and the eye are closely related - strong smells make your eyes water, bright lights can make you sneeze, and sneezing automatically makes you shut your eyes because the nerves are all so close.

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.

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.
