First of all lets take a look at why we sneeze. Sneezing is a way that your body gets rid of bad things that are in your nose. These things might be bacteria, germs, and other things. You also sneeze when you smell pepper because your body does not like pepper! When you suddenly you see a bright light like the sun or a light bulb then you feel like you are going to sneeze. Most people feel like you do when you see the light.
It is believed that some people can sneeze with their eyes open and some people can’t. Sneezing is a reflex and so is closing our eyes. We have no control over whether or not we close our eyes when we sneeze. Some people don’t have reflex, so when they sneeze then their eyes won’t close.
No one knows the reason you close your eyes when you sneeze. There are many possibilities. Some people think it is to protect your eyes from flying goop. Most doctors think that it is still a reflex, or we just can’t help it.
But it could also be simply because a 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).
Because sneezing is a common phenomenon and rarely harmful, little research has been conducted to demystify the sneezing experience. However, observational evidence, anecdotes, and a few studies provide insight into some common beliefs about sneezing.
Some people used to believe that your heart takes a break during a sneeze, this is actually not the case. When you first inhale before sneezing, the pressure in your chest increases. Then, as you exhale forcefully during the sneeze the pressure drops. Alterations in blood flow to your heart produced by these pressure changes, can affect the heart rate. However, the electrical activity in the heart marches on unimpeded–you remain very much alive throughout your sneeze!
Will your eyes pop out of your head if you keep your eyes open during a sneeze? Not true. The few people who can naturally keep their eyes open while sneezing manage to keep them firmly inside their head. There is no physical mechanism involved in a sneeze that could make your eyes pop out.
Can sneezing after sex prevent pregnancy. The theory behind the sneezing idea is that if a sneeze is powerful enough to shoot mucus out of one’s nose, it must be strong enough to expel the semen from a woman’s vagina after sexual intercourse. However, although some semen may be expelled after a very powerful sneeze, even the most outrageous sneezing fit wouldn’t get rid of enough semen to provide reliable contraception.
Although many superstitions associate sneezing with danger or even death, sneezing is just a natural reflex, much like itching and tearing. Most of the rumors about sneezing are not true. Your heart does not stop, people can sneeze with their eyes open, and pregnancies can and do occur despite a sexually active sneezer’s best efforts. There is at least one useful truth to be found among all these sneezing myths: once you do it there’s no turning back. If you block a sneeze, you may not be able to hear your much deserved “God bless you.”
