A member asked:

Is inhaling & exhaling entirely through the nose a healthier way to breathe (ie strengthen the lungs) instead of thru the mouth?

Dr. John Chiu answered

Specializes in Allergy and Immunology

Air going through the nose gets moisturized, warmed up, and filtered and thus it is a preferred way to breathe except during strenuous exertion when you will need to breathe through your mouth. Neither method strengthens your lungs.
