A sneeze is a result of a sudden relaxation of the diaphragm together with the intercostal muscles that expand our lungs and abdominal muscle contraction. This results on a mass commpression effect of the lungs on a short onset and causes a violent expulsion of air in the form of the sneeze.

The sneeze is a result of an noxious or allergen that enters the uuper respiratory tract and is detected by neural cells present there. This sends signals to the thalamus and the thalamus sends out signals to the muscles mentioned above and produces the sneeze. The main aim of the sneeze is to get rid of the insulting agent responsible.

This answer seems most informed and explains the question with simple body mechanics. A trifle boring but probably true. I wondered myself if the body developed a high sneeze rate as a way of spreading germs in a survivla of the fittest kind of way but I seem to be on my own and probably wrong.

Answer 2

Self Defense

Answer 3

Thats a lie. I sneeze out of my mouth. A lot cleaner.

Answer 4

To make sure they have a clear landing.

Answer 5

Sneezing is (usually) to clear some foreign object from our windpipe. Some objects might come out very easily and only need a leisurely 90km/h, but others might be stuck or have smaller surface area, and require more. I guess sneeze level could be adjustable, but the body seems to feel if it is worth sneezing it is worth sneezing at full blast.

With increasing pollution, as evolution continues we can look forward to sneezing faster and faster. It is estimated that by the 66th century sneeze speed will be approaching mach 1.

Answer 6

SNEEZING IS JUST ONE OF MANY WAYS FOR YOUR BODY TO EXPELL FOREIGN SUBSTANCES. NOT JUST IMPORTANT FOR HEALTH REASONS, THE SNEEZE IS A SATISFYING WAY TO GET RID OF THAT TICKLE IN YOUR NOSE. BECAUSE YOU NOW KNOW THAT YOUR BODY CREATES THE FORCE OF 100 MPH, PERHAPS YOU WON'T HOLD BACK YOUR SNEEZES ANY LONGER. THINK ABOUT IT; HOLDING SNEEZES IS REPORTED TO HAVE CAUSED ANORISMS, STROKES, AND EVEN HEART FAILURE. BLOOD VESELS POPPING, PEOPLE DYING, ALL BECAUSE YOU CAN SNEEZE AT 100 MPH. ALSO THE FORCE OF A SNEEZE IS SO STRONG THAT TWISTING YOUR BODY AS YOU SNEEZE, TWISTING YOUR NECK, CAN CAUSE DISKS IN YOUR NECK AND BACK TO SLIP. PAIN FROM SNEEZING!
