Clamping your nostrils and mouth shut might avoid disturbing others. But it could damage your eardrums or sinuses or cause an ear infection.
Sneezes are surprisingly forceful. The sudden, powerful expulsion of air can propel mucous droplets at rates of up to 100 miles per hour.
Some people are starting to sneeze because of the arrival of warm weather and allergies. A hallmark of allergy-related sneezes is sneezing two to three times in a row.
Allergist Rachel Szekely MD says to let those serial ah-choos roll.
“Occasionally, people will cause some damage to their eardrums or their sinuses if they stifle a very violent sneeze,” says Dr. Szekely, an immunologist in the Department of Pulmonary, Allergy and Critical Care Medicine at Cleveland Clinic.
Some people sneeze because of colds. Colds may produce a yellowish nasal discharge that signals an infection.
It’s best for that discharge to move out of the body. Stifling a sneeze only keeps it in the body — and could move it further inside.
“By stifling a sneeze, you could push infected mucus through the eustachian tube and back into the middle ear,” Dr. Szekely says. “You can get middle ear infections because of that.”
Sneezing is a protective reflex. It means an irritant has gotten into your nose that your body wants to keep from getting to your sinuses or lungs. When you sneeze, your body is trying to rid itself of the intruder.
Some myths have grown up around stifling a violent sneeze. It won’t cause a stroke or blow out a kidney.
All the same, Dr. Szekely says, let your body do its thing and sneeze. Just cover your mouth and nose.
