Can you sneeze in your sleep?

My husband does it all the time and he can cough in his sleep and talk in his sleep...\nHe is a barrel of fun when I am trying to sleep...

It 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.

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.

Sneezing is defensive act by the nose to bring out any foreign body-ouside elements- outside.  So it should not be stopped.

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.

Its to keep your eyes from popping out of their sockets! Just kidding.\n\nActually, ASK Yahoo already adresses this question at http://ask.yahoo.com/20050721.html\n\nHere's a copy of their answer:\n\nDear Yahoo!: \nWhy is it impossible to sneeze with your eyes open? \nKevin\nEl Monte, California \n \nDear Kevin: \nThe received wisdom states that if you don't blink when you sneeze, your eyes will fly out of your head. Thankfully, as is often the case with urban legends, this theory is a load of hooey. Your eyeballs are safe and sound in their sockets. For a funny pictorial representation of this hypothetical scenario, check out this urban myth page from MTV: http://www.mtv.com/onair/big_urban_myth/birth/index.jhtml?choose=Sneezing+To+Blindness\n\nIn reality, a sneeze is simply an involuntary nervous response to nasal irritation. According to this nifty science blog entry (http://sxxz.blogspot.com/2004/12/sneeze-science.html), the sneeze impulse affects a variety of body parts, including the abdomen, chest, neck, and face. During a sneeze, the impulses that travel through your face cause your eyelids to blink. This response is entirely automatic. There's nothing you can do about it. Sneezing puts a lot of pressure on your head and respiratory system, so blinking is probably a protective mechanism. \n\nThe point is that all of these responses (the abdominal contraction, the sharp burst of air out of your lungs, the general lunging movement) are intertwined. When you sneeze, you can't do one without the other.

Yes, I have pulled rib muscles several times from sneezing. Once when I sneezed while I was lying down, I severely pulled a muscle in my neck. That was a really embarrassing way to be injured for several weeks!

No...have you? (why don't you add some details to your question so we can find out if you have heard one)\n\nThanks for the explanation...I have no idea why you're hearing sneezes. Maybe it's a ghost or a spirit...

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

Yes. When you sleep, its kinda like recharging the battery in your car. If its low, then nothing really works right. This includes your immune system.

you may be allergic cold wind or cotton fibre. shift your bed away from window, if sneezing still persists take steam inhaling. this may give temporary releif, if it still persists consult a Doc.

When you sneeze, it is said that your heart stops beating. \nWhen you cough, your heart is not affected.

No it is not possible.  There have been studies done that at the exact moment you sneeze, all other brain function ceases.  You have no brain waves, no heartbeat and the only breathing that occurs is the air that is forced out of your lungs.  For a split second, you are dead.  Just a bit of usless trivia I picked up a few years back.

I read something about it being impossible to sneeze with your eyes open. Even if you try your eyes would automatically close. I think they would pop out if they were taped open.
