"Close association between the eye’s optic nerve and nerves causing the sneeze reflex may explain why an estimated 5-25% of people sneeze with sudden exposure to bright sunlight or other light sources.\n\nSudden bright stimulation of the eye that occurs after a person has become adapted to darker surroundings is thought to bring on the condition, known as photic sneeze reflex."

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.

It could be an Ophthalmic Migraine.\n\n"Ophthalmic migraine is quite common. Patients usually experience visual symptoms of seeing bright zig-zag type lines in their central or peripheral (side) vision. These bright lines may have associated flashing light sensations and sometimes can interfere with vision. There are many variations of symptoms. These symptoms usually resolve spontaneously after several minutes but usually less than one hour. Often, rest in a darkened room can be helpful during a migraine attack. Medical treatment is usually not necessary."

Everyone has their own unique style of sneezing.  Based on what you are saying I am guessing that when you sneeze you put pressure in your throat and on the back of your neck and into your shoulders.  The spinal nerves that control your arms are in the back of your neck just at the area where if you put your fingers on the back of your neck and tilt your head backwards, your fingers would be sort of pinched between your back and your head.  If, when you sneeze violently, you put a lot of pressure on your head downwards and bring your shoulders up, it could pinch off those nerves enough to send pain down your arms and even into your hands.  In order to avoid this, just try to do the impossible--change your style of sneezing.  Good luck with that.  If I have not described the way you sneeze, then, I'm sorry, I don't know why you get pains in your arms.\n\nSherril H.,  R.N.

Of course, its a perfectly natural situation. Something that irritates the nostrils' delicate lining makes the nerve endings not only say that 'hey there's an itch here too!' but the sneeze reflex also responds to the irritant.

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

you sneeze once and you rub your nose and it might tickle your nose so you sneeze!

I'm allergic to something that no doctor has yet been able to figure out.  It strikes me at the worst times (usually when I'm eating or drinking) and it was extremely hard to control.  What I've learned to do is to hold a piece of ice to the top of my mouth with my tounge.  If you press the ice firmly enough to the roof of your mouth the sneezing should stop (at least, it does with my sneezing).

Photic sneeze reflex (also referred to as sun sneezing and whimsically called ACHOO, a backronym for Autosomal dominant Compelling Helio-Ophthalmic Outburst) is a medical condition by which people exposed to bright light sneeze. It has been suggested that the photic sneeze reflex occurs only after someone has been adapted to the dark for at least five minutes, although this is not certain, and is not uniform amongst people with the photic sneeze reflex. The photic sneeze reflex can also cause one to sneeze many times consecutively. The condition occurs in 17% to 25% of humans with more common occurrence in Caucasians than other human races. The condition is passed along genetically as an autosomal dominant trait.

I have heard babies sneeze while they were sleeping.

You might be suffering from allergies. It is common around this time of the year. Try taking Claritin, it works great for sneezing.

Changes in breathing (rapid inhalation/exhalation) and heart-rate might be linked to it somehow. That might explain the venous involvement...something to do with circulation perhaps which is aggravated by the sneezing fit?

urination...busted blood vessels in the eye..cracked ribs.  I myself had my hymen break when I sneezed.  You're right crazy things happen.

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.

A search of the Internet yields a lot of sites that basically say that it's a known phenomenon, but science hasn't figured out why.\n\nThere is speculation that the optic nerve gets overloaded by the bright light and "leaks" onto the nerves that trigger sneezing.

I'm sorry I don't have an answer for you. I just wanted to say that my ears do that as well. I cough, I feel like I'm gagging, my eyes water, and sometimes I even sneeze. I hate cleaning my ears. I just wanted to tell you that you're not alone.
