blowing

Nose-blowing is the act of expelling nasal mucus by exhaling forcefully through the nose. This is usually done into a facial tissue or handkerchief, facial tissues being more hygienic as they are disposed of after each use while handkerchiefs are softer and more environmentally-friendly.
Nose-blowing may be used to alleviate nasal congestion (stuffy nose) or rhinorrhea (runny nose) resulting from colds, seasonal allergies, expel excessive nasal mucus created from crying or to expel nasal irritants.
