Nonallergic rhinitis is the {inflammation}[a natural biological response to harmful triggers such as infectious agents, damaged cells or irritants; the five signs of inflammation are heat, pain, redness, swelling, and loss of function] of the nose, not caused by an allergy. Instead, nonallergic rhinitis may be due to hormonal changes, looking at bright light, spicy foods or certain irritants. Nonallergic rhinitis symptoms are similar to those of hay fever (allergic rhinitis), but with none of the usual evidence of an allergic reaction. Nonallergic rhinitis can affect children and adults.
