Controlling asthma may mean controlling allergic rhinitis in some patients, according to allergy and asthma experts. The majority of asthma patients have rhinitis, and patients with rhinitis have a much higher prevalence of asthma than those who do not have rhinitis.

Although the link is not fully understood, one theory asserts that rhinitis makes it difficult to breathe through the nose, which hampers the normal function of the nose. Breathing through the mouth does not warm the air, or filter or humidify it before it enters the lungs, which can make asthma worse.
