Does sunlight makeyou sneeze?

My brother sneezes every time he walks into the sunlight. It's called "Autosomal dominant Compelling Helio-Ophthalmic". \n\nHere's some info on it: http://en.wikipedia.org/wiki/Photic_sneeze_reflex

Because otherwise some 'thing' in your eyes will get damaged by the fastness of a sneeze, and therefore the eyelids react with shutting when sneezing.\nDon't really remember more than that, I read it 3 years ago somewhere... :S

the nose has erectile tissue in it, and can sometimes cause a little tingly feeling in other areas when theres a sneeze.

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

Mechanism of sneezing - Normally, sneezing is an involuntary reflex, which is controlled by a complex interaction of nerve fibres. A variety of receptor sites, situated in the nose, reports about the irritation or foreign substance to the brain for inducing sneezing by releasing histamine, for clearing the nose. Receptors are sensitive to infection, touch, smells of dust, chemical gases, fumes, temperature and exposure to extreme cold air and water (the main offender). Usually, sneeze begins with a deep inspiration and closed glottis, which suddenly opens after gaining pressure from contraction of the diaphragm, abdomen muscles and other muscles which compress the lungs to let out the trapped air with force through nose and mouth. So with an explosive sound, throw of air occurs as a sneeze. Sneezing also involves contraction of the muscles of face, neck and eyes. Sometimes, sneezing air speed is measured more than 120 km/per hour. Normally, people sneeze once or twice during early morning or daytime to clear the nose.\n\nFor more info, go to the source...

It's called Photic sneezing, and it's not too uncommon. There's thought that the change in lighting that triggers the changes in your eyes (your retina getting smaller in bright light) for some reason sends a signal to your sneezing reflex as well.

It's not. Or more accurately, I'm almost certain it's not. I myself get that when I sneeze hard, it's just body's reflex to the sneeze. I did have lab testes done, and I was 100% fine.

Probably because your face contorts (even if only slightly when the light source is mild), and that adds to the irritation in your nostril, triggering off a sneeze.

the only systems that a sneeze can effect are:\n\nrespiratory (the heart skips a beat when you sneeze [hince why we say bless you])\n\nmuscular (the muscles tighten up when you sneeze [if someone were to sneeze 100 times in one day, they will burn 5 calories])\n\nof course your nervous system ( when you sneeze and your body moves, reacts, or holds your hands up its because of your nervous system tells it to do so.)\n\nwell your immune system is kind of effected. ( its the reason why youre sneezing in the first place)( its getting rid of unwanted air or particles that recently entered your body)\n\nand thats all i believe.

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

Yes, that is why people say "God bless you" after you sneeze.

It is the strain of sneeze.

"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 a superstition.  People used to believe that the devil could enter you when you sneezed.  God Bless You was a way for others to try to help prevent that.
