Yes giggling can be contagious.  \nYes laughing is good for you.\n\nI was at a jazz club last night, and my friend had a funny picture of her cat.  It was hilarious.  We laughed so hard, you know the belly-laugh.  A few other people who saw the picture of the cat joined us laughing.  Then a man takes a look at the picture, and he just stares at it then looks at us like we're all crazy, which made us laugh even harder.  So, yes, many of us caught the giggle bug, and the one escaped it.

Sneezing contracts a lot of the muscles in your face, including the ones controlling your eyelids.\n\nAs for the people answering with the popping eyeballs: LOL!

The particles irritate the lining in your nose, and your body recognises it as foreign matter that it needs to expel....quick.  So the sneeze happens to push the pepper out...far and fast.

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.

Yes. This is a very interesting question and have an answer everyone must know. \n\nWhenever we sneeze, our heart stops. This is the only time in the life (of a living person) when a heart stops. There has been a convention of different cultures around the world to welcome (or say welcome back) just after sneezing. These people don't know why we welcome the person who just sneezed. But the truth is that, he/she just came back from a situation between life and death.

Sneezing is a reflex that occurs when something irritates the mucus membrane in our nose. Particulate matter, bacteria, and other such things get bogged down in the mucus and tiny hair-like cilia wiggle the potentially hazardous material toward the front of the nose or down the back of the throat. A message is sent to the brainstem, which sends messages all over the body. What happens next?…that great spasmodic reflex we call sneezing, a well-coordinated effort of many muscles working at once…your diaphragm muscle flexes, as do your abdominal muscles, your chest muscles, the muscles controlling the vocal cords, and the muscles in the back of your throat…your tongue raises to block your mouth…and your eyelids close. Air is forced out of your nose, sending thousands of bacteria-filled globules of snot into our immediate atmosphere…and then, as good manners dictate…people will invoke higher powers to bestow upon you a blessing. A most sanctimonious event, indeed!

its possible that when you sneeze, your eyes close reflexively, to prevent your eyes from getting contaminated by whatever is coming out of your nose and mouth.  As well, the urge to sneeze (that tingling feeling in your nose) may play a part, due to the optic nerves for your eyes laying close to the nerves for your nose and recieveing some residual signal...

As long as there are sores in the mouth it is contagious. But be careful it can be hell to get.

If you did manage to sneeze with your eyes open, your eyes would pop out of your head.   Er, no. As discussed above, some people do manage to sneeze with their eyes open, and they don't go blind from it. Eye sockets are made of bone, they aren't connected to the nasal passages, and there are no muscles behind the eyes that contract when you sneeze, so there's really no mechanism involved in a sneeze that could force your eyes out of their sockets. Even if there were, human eyelids aren't particularly strong, so simply closing your eyes during a sneeze wouldn't be sufficient to keep them in their sockets if a sneeze truly had enough power to dislodge them. (In any case, some people — due to circumstances such as birth defects or injury — do not have eyelids. Were the "eye-popping" rumor true, all of those people would have to spend their lives in constant mortal fear of sneezing.)

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...

yes it is contagious, some are mild but many are sever, depending which organ was infected.  \n\nin addition, viarl infection are also contagious.

I recall reading that waaaay back when...sneezing was a "sign" that one had evil spirits or the devil in them.  Blessing them was to try and help them.  I've never heard of someone be blessed for coughing, though.

Well, I don't know why yawns are contagious because scientists really don't know what cause yawn's in the first place. However, on a lesser level, I believe yawns are contagious because when you see someone yawn, you tend to think of how tired you are. Therefore, you yawn too. And plus it is pretty amusing when you have a yawn fest with someone and just cannot stop yawning back and forth.\nHope this helps!
