closing your eyes is a natural reaction to many events.  if someone blows in your eye, you will naturally try to shut them.  sneezing elicits this response because you are going through a spastic motion and there are lots of particles being hurled into the air.  it is hypothesized that we evolved this reaction to sneezing to keep those particles out of our eyes.\n\nsneezing involves releasing the air in your lungs at very high velocity.  for the most part, your nose and mouth can expel this gas before the pressure in your sinuses gets to a point that it causes your eyes to pop out.\n\nyour eyelids alone can't prevent your eyes from popping out.  try to close your mouth, nose and eyes as tight as you can and see how the air gets out.  also tell the doctors at the emergency room

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.

Sneeze is an involuntary violent expiration of air through the nose and mouth. It results from stimulation of the nervous system in the nose, causing sudden contraction of the muscles of expiration. The stimulus can include any irritating factor in the nose—inflammation of the tissues as the result of a cold or infection, allergic irritants (hay fever), or irritating substances such as dust or pollutants in the air. An occasional sneeze usually has little significance. Repeated sneezing indicates that some condition of the nose or in the immediate atmosphere requires attention.

The most common belief is that your soul leaves the body for a short time, so by saying "bless you! (from "bless your soul") the person would be protected. It is also true that your heart stops when you sneeze. The "bless you" is also supposed to keep the devil from entering your throat when sneezing. In Romanian, for example, we say either "health" or "luck", we don't use the "bless you".

When you sneeze the air from your nostrils come out with great force (infact stronger than the strongest wind!).\n\nIt is said that if you sneeze with your eyes open, your eyeballs might pop out!! It may be possible as our eyeballs are just held in sockets and do not have supportive structures to hold them in place.\n\nWhen you try to hold back a sneeze, your eyes start watering a little bit.

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?

This has been recognized in medical journals for at least 40 years, and is called different things, including the "photic sneeze reflex" and even the "ACHOO syndrome". In a few instances the reflex has been documented by shining bright lights at people to make them sneeze, so it probably really does happen. \n\nNobody is really sure why.  Apparently, somehow, the nerve pathway associated with sneezing is stimulated with the exposure to bright light.

Eyeballs popping out when you sneeze is an urban myth.  I have intentionally kept my eyes open while sneezing with no ill effects.  The eye sockets are made of hard bone and are only connected to the sinuses through tear ducts.  Sneezing is a reflex action to the presence of an irritant in the sinus passages.  I would suggest that the reflex involves closing the eyes to prevent the transmission of this irritant into the eyes.

The actual reason is to combat the pressure build up in your sinuses. \nSneezing releases alot of force.\nYour eyes are linked to your sinuses, and well - you wouldn't want to blast them out of your head now would you?

A yawn is in response to too much CO2 in the blood stream.  When you yawn there is a negative feed back loop in operation which tells the diaphram to contract (take a breath) because there is too much CO2......the yawn actually increases CO2.\nThe sneeze is due to irritation in the beginning of the respiratory tract, it expells such things as dust, bacteria and other irritants from your nose and sinuses.\nA hiccup is a sligh malfunction or mistiming if you will of the glottis which is a membrane that closes in your throat to prevent food from going into your lungs when you swallow.  Whenyou ge tthe hiccups it starts to close while you are taking a breath or expelling a breath.  It just takes a bit of time for your body to reset when it closes

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.

Your eyes will NOT pop out!  It is simply a protective reflex.  There is so much going on: abdominal contraction, sharp burst of air from the lungs, lunging movement that the body closes the eyes automatically to protect them.
