How does sneezing effect the Circulatory System?

due to the sudden jerk you get while you sneeze, you automatically make you body tight and then suddenly it becomes loose. thus the blood pressure increases. \nSometimes people feely giddy due to a sudden and big sneeze. this is because, the brain cannot coincide with the blood pressure. thus it happens. but remember this is all just for quite a fraction of a second. \n\nHope it was clear enough.

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

Smoking affects the respiratory system by coating the insideof the lungs with nicotine which decreases the ability of the aveoli to move air. That's why smokers don't have very good stamina for sports. \n\nIt affects the circulatory system by constricting blood vessels. This increases the rate that your heart has to work (blood pressure goes up, etc.)

Tidbitonebox7 is on the right track.  The nerves that serve your eyes and nose are very close together, and strong stimulation of one can affect the other.  So, if you get a strong light stimulation in your eyes, it can affect your nose nerves and cause you to want to sneeze.  There are similar affects and effects throughout the body.

As in humans, sneezing is normal. It's a reflex for expelling something in the nose that doesn't belong there.

First of all not all people sneeze multiple times in a row.  The reason for sneezing is your body's primary defense against something trying to get in that shouldn't be there such as dust, pollen, bacteria, etc.  The little hairs in your nose are very sensitive and when something moves them it gets trapped inside and sneezing is how your body expels the invader from your nose or throat if it made it that far although coughing is usually more related to the throat.

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.

When people sneeze, they tense up thus their muscles put a strain on their joints.  This is actually one of the reasons people in car accidents get broken bones.  Not because of the actual crash, but because of tensing their muscles which result in the muscles breaking the drivers own bones.  Also the fact that you pop a lot of your joints doesn't help.

Actually, yes it can be dangerous. Holding in a sneeze can force bacteria into your ear, and can even cause your eardrum to rupture. In addition, it can cause chest pain, and stress on the throat. In other words, if you have to sneeze, let it out! In class you might want to sneeze (or cough) into the bend of your elbow. It's the best place. Coughing or sneezing into your hand spreads germs.

No. Blocking a sneeze does not kill brain cells, rather it can give you a stroke. Such a block has a high chance of raising the internal pressure of capillary brain vessels and cause a tear in them. If such thing occurs most of the time you need a surgery requiring opening the skull.

You sneeze with your eyes open.

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 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

No it is not possible.  There have been studies done that at the exact moment you sneeze, all other brain function ceases.  You have no brain waves, no heartbeat and the only breathing that occurs is the air that is forced out of your lungs.  For a split second, you are dead.  Just a bit of usless trivia I picked up a few years back.

A sternutation or, more commonly known, sneeze is a semi-autonomous, convulsive expulsion of air from the nose and mouth. This air can reach speeds of 70 m/s (250 km/h) and an unimpeded sneeze sends two to five thousand bacteria-filled droplets into the air\n\nThis was also interesting:\n\nFebruary 2002 - Your brain musters a host of muscles to clear irritants from your nose at speeds up to 100 mph.\n\nEver try to stop a sneeze? Not easy, is it?\n\nSneezing is a reflex. "When your nose itches you sneeze," just as your knee jerks when a doctor taps it, says California allergist William E. Berger, M.D., a member of the American College of Allergy, Asthma and Immunology. "Closing your eyes when you sneeze is also part of the reflex reaction."\n\nSneezing may seem simple, but it's more involved than you think. Here's how it works: Your nose often warns you a sneeze is coming. An irritant makes your nose start to itch or tickle.\n\nThen the part of your brain termed a "sneeze center" sends a message to designated muscles. "The signal from the brain tells our body to sneeze as a means of clearing out the irritating particles," says Dr. Berger.\n\nThe chest, abdomen, diaphragm, vocal cords, throat and eyelids join in a certain order to launch a sneeze. Presto -- your nose releases the irritant that's causing that itch. A sneeze propels particles from your nose at a speed of up to 100 miles per hour.\n\nSome particles sneak into your nose in a normal breath. A lot more come from colds or allergies. But the cause of your sneeze could also be bright sunshine.\n\nStrange as it sounds, bright light causes one out of three people to sneeze. Some doctors call them "photics," from the Greek meaning "of light." Photic sneezers can blame their parents -- you inherit this trait.\n\nIf your sneeze comes with chest congestion, headache, yellow or green nasal discharge, fever or a stuffy nose, you may want to see a doctor. You could have a cold or allergy.\n\nYou may be tempted to stop a sneeze. Don't.
