Nose Blowing and Colds (U.S., Denmark)
If you have a bad cold, think twice before blowing your nose hard. Scientists at the University of Virginia and the University of Aarhus in Denmark examined adult volunteers with CT scans and found that blowing the nose deposited nasal secretions in the sinuses, though sneezing and coughing did not.
