Breathing by mouth is harmful in the sense that the air which is taken in is not filtered , it is taken in with its impurities . Hence it is said that we should not breathe by mouth and always breathe via our nose. The nasal way of breathing is the best way because our nose contains nasal hair which are tiny hair inside the nose which filter the air and make it purified and hence safer .
