Technique The tissue or handkerchief is held gently against the nose. Prior to nose blowing, a deep Inhalation through the mouth or nose provides the air required to eject the nasal mucus.

Nose-blowing generates high pressure in the nostrils. When this pressure is added to a dry nose, it could rupture inside the nose, resulting in a nosebleed.

In a 2000 study, doctors squirted dense liquid dye, which could be seen on , into the noses of several adult volunteers. The volunteers were induced to sneeze, cough, and blow their noses. It was found that the typical pressure of nose-blowing was 1.3 pounds per square inch, ten times greater than that generated by sneezing or coughing. showed that nose blowing sent much of the dye into the paranasal sinuses rather than expelling it out of the nose. The doctors suspected that nose-blowing may increase the risk of Sinusitis by sending bacteria-filled mucus into the sinuses.

In extremely rare but documented cases, nose-blowing has resulted in unusual conditions, such as in the case of a woman who her left eye socket after blowing her nose.
