well...I think that`s because when you sneeze, cough or laugh hard...your diaphragm contracts and the body is concentrated very hard on that muscle.When you cough..sneeze etc. you blow out CO2 and your body tries to get rid of it with the help of every space that leads from your body outside your body, for example : when you sneeze you have tears coming out of your eyes...that`s because it`s a sensitive tissue that produces water and has to get out fast from your body in case of emergency ... like crying(because of the nerves that must relax), laughing hard etc... I hope the answer helps..and you also must consider the answer above...with the weak muscles

Say 'Bless you' after someone sneezes. It's supposed to keep the devil at bay. If the Devil doesn't materialise then you'll know it worked.

If your heart stops your dead or in cardiac-arrest, plain and simple. Sneezes increase the pressure in your chest and change blood flow, causing the heart to "flutter" a little bit. When u sneeze your heart doesnt stop or pause or anything, it may speed up, but stopin is a negative. \n\nThe "bless you" thing came from the plague, when people sneezed it was a sign of the plague. They said "bless you" so that incase that u didnt make it, you would still go to heaven after u bit the dust.\n\nFinal Answer: Hearts dont stop from sneezing. "Bless you" is said from the days of the plague.

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 said that all bodily functions stop when you sneeze... save the actual sneezing function itself. \n\nDon't know if this really answers your question, but it seemed applicable.\n\nHave a good one!\n\n-Jordan

it helps prevent (doesnt completely block) the germs from flying over the entire room or onto other people around you, but do know that if you dont wash your hands right after sneezing you are spreading the germs that are then on your hand.  it is reccomended to sneeze into a tissue or a handkerchief to prevent the spreading of germs.

I think that's what they call hydrostatic shock, the same thing that kills you when you are hit by a high speed bullet (though in this case, it is a smaller and non fatal version.) \n\nLook at what happens. You draw in a breath, compress it and let it out explosively. There is such a thing as recoil. You expell the breath in the sneeze, but then the back pressure is felt in your veins and arteries; it tingles and it hurts for a little while. \n\nI get it too, sometimes. It is uncomfortable but not harmful, unless you are having an allergy attack and sneeze dozens or hundreds of times in a row. Then it could cause tiny blood vessels to burst and you might get odd looking bruises. \n\nDo your ears pop when you sneeze, sometimes...? Do you sneeze through your nose or mouth? You might try doing it the other way. If you can, try covering your face with a tissue/hankie before the sneeze is ready to come out and relax. If that doesn't help, try seeing an ear/nose/throat specialist, or an allergist. Good luck!

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

Pretty much the same reason people sneeze when they get a cold: it's one of the mechanisms the body uses to get rid of infection, poison or other bad elements.  With a cold, of course, the infection is in the respiratory system; with diarrhea and/or vomiting, the problem is in the gastrointestinal tract.  It's your body's way of "evacuating the building" so your antibodies and other immune mechanisms have a better chance of conquering the infection.\n\nThere can be other reasons for diarrhea, however.  One is where you have eaten something which for some reason your body isn't equipped to digest properly.  There are also some GI diseases where your digestive system isn't working the way it should.  One such disease is called Irritable Bowel Syndrome, where your digestive system is overly sensitive to irritants.  Stress is another thing which can cause temporary diarrhea.

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!
