Inflammation and irritation of the nasal passages
cause a reflex reaction within the lungs, perhaps through nerve
Relatively cold, dry air stimulates asthma symptoms when
allergic rhinitis sufferers must breathe in through their mouths because they
have stuffy noses.
Drainage from the nose caused by allergic
rhinitis irritates the airways in the lungs.
Cells that trigger
inflammation or chemicals that cause inflammation travel through the
bloodstream and cause inflammation in the lungs.
