Do we sneeze while we are asleep? Is it even possible?
925113
Well the fact is that humans cannot sneeze while asleep.\nSneezing requires a reflex mechanism, wherein the sensory nerves in our upper respiratory tract, esp nostrils, are stimulated by some stimuli (mechanical or chemical or other)and these nerves then go to the CNS (i.e brain) and as a final process excite the nerves which supply muscles pf our respiration and the pharngeal region and the man sneezes thus. You must \nknow that this reflex is a natural means to protect our sensitive upper respiratory tract from harmful influnces or, more appropriately, external influences, be it a solid or a gas or as a response to some infection. Now when the man sleeps, his brain is not working at its normal levels and so even though the man's nerves have some external factor acting upon them,\nno reflex is initiated and the man doesn't sneeze. You must also know that when the stimuli continues or crosses a particular \nlevel, it changes from an irritative agent to a source of maybe say pain and the the man can have a disturbed sleep; there is a threshold for every thing.

when you are sleeping, your breathing pattern slows down. Therefore you will not inhale as deep and the debree doesn't trigger the adnoids that make you sneeze!\nThe position you lay in will have an effect also\non your breathing patterns.

A sneeze is the fastest known action that a human can perform.  It is involuntary and can make the head mover VERY sharply.  Maybe our eyes close so that we don't get anything in them when our head jerks forward?  Dust, leaves, branches, etc. would be both painful and dangerous if they got into our eyes while we were moving our head at high speed.\n\nAccording to Wikipedea:\nIt is almost impossible for a person to keep their eyelids open during a sneeze, although some rare individuals report having little if any trouble doing so. The reflex of shutting the eyes serves no obvious purpose: the nerves serving the eyes and the nose are closely related, and stimuli to the one often trigger some response in the other.

Yes it is possible Because when a man is asleep the closing of the eye is controled by involuntary part of the brain. The porpose of closing the eye is actuly to prevent the entrence of particles which can demage the eye. Since the process is controlled by involuntary part of the brain then it is possible for man to sleep without closing the eye. Becouse the process is not under his/her voluntary control ie s/he doesn't think of it.

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...

Hmm, if I had to count how many times i sneezed every day it would probably end up being a couple hundred each day, lol! I have very bad allergies and I am constantly sneezing. Usually after the 3rd sneeze, my family members will tell me to shut up(sarcastically) because they know that I will go on forever.

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.

Many people thought that sneeze is impolite, it's true if you do it on purpose. But it is natural and it is good because when you sneeze bacteria that try to come inside your lung will come out. Try to cover your mouth and nose when you feel, you will sneeze.

it is not possible looking normal or funny your eyes automatically close when you sneeze because your muscles contract

Some people do find that bright light causes them to sneeze. It seems to be biological or hereditary. If you walk outside into the bright sun or look at a bright light you sneeze.\n\nIts called Photic Sneeze Reflex!!

In the short term you can stop sneezing by pressing hard on the middle of your top lip. That disrupts the nerve impulses from the nose and will kill most sneezing. \n\nIn the long term you need to treat whatever os causing you to sneeze, whther that's an allegy or an infection. Anti-allergy medication often works.

I have heard babies sneeze while they were sleeping.

yes.  you sneeze when something irritates your inner nose.  all that happens is that a little piece of dust gets in the wrong place, and you wake up sneezing--but this does not happen very often.  it is very rare
