If you hold in a sneeze, will it really rupture a blood vessel in your brain?

Answer 1

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 250 mph and an unimpeded sneeze sends two to five thousand bacteria-filled droplets into the air

Cause
Sneezing is generally caused by irritation and some times bacterial clog up in the throat, lungs or in the passages of the nose. Allergens such as pollens, pet dander, house dust mites, as well as nonallergenic particles are usually harmless, but when they irritate the nose the body responds by expelling them from the nasal passages. The nose mistakes strong odors, sudden chills, bright lights, and even orgasms in some people for nasal irritants, and it tries to defend itself with a sneeze.

Eyelid close response
It is almost impossible for one to keep one's 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. The closing of the eyes may be to protect the tear ducts and blood vessels from bacteria expelled in the sneeze

The old wives' tale warns us that if you hold in a sneeze, your head might explode. That won't happen, but you can do yourself some harm. The air expelled by sneezes is said to travel at up to 100 miles per hour. Holding in a sneeze can potentially cause fractures in the nasal cartilage, nosebleeds, burst eardrums, hearing loss, vertigo, detached retinas or temporary swelling called facial emphysema. So it's best to let your sneeze fly, but please cover your nose and mouth.

Answer 2

A myth, fortunately for all us hold in a sneeze from time to time. Now is one is on an anticoagulant (a blood thinner), and have violent sneezing and coughing spells, it is then possible, not likely but possible to cause a bleed from the pressure of the coughing or sneezing on the brain. Thanks for the opportunity to address your question.

Answer 3

Holding in the sneeze will momentarily cause an increase in your blood pressure in your head. In otherwise healthy individuals this more or less wouldn't be a problem. But people with underlying vascular conditions may have problems.

Answer 4

Answer 5
