Prolonged nasal obstruction is usually caused by the curvature of the nasal mast, the size of the nasal flesh, the growth of nasal flesh, nasal polyps (which may be caused by allergies or sinusitis) and chronic sinusitis. Thanks to the nose, our breathing organ, the incoming air is heated, moistened and cleaned before it reaches the lungs. This purification and conditioning task of the nose is very important for lung and general body health.
