Perfume. Cold air. Exercise. Why can they make your nose run?
A runny or blocked nose after perfume, cold air, exercise, smoke, alcohol, or a sudden weather change is not automatically an allergy.
Non-allergic rhinitis—or non-allergic rhinopathy—is a pattern in which the nose becomes unusually responsive to non-allergic triggers. Congestion and clear discharge are common, and some people also report post-nasal drip, sneezing, cough, throat clearing, or altered smell.
The distinction is not always obvious. Allergic rhinitis can produce overlapping symptoms, and allergic and non-allergic patterns may coexist. Infection, medication effects, rebound congestion, structural narrowing, and sinus disease may also need consideration depending on the history.
A brief symptom diary can be more useful than trying to remember isolated episodes. Record the trigger, timing, duration, whether one or both sides are affected, and whether itch, sneezing, eye symptoms, blockage, or discharge occur with it.
The purpose is not to diagnose yourself from a trigger. It is to make the pattern clearer so that assessment and treatment can be better targeted.
If symptoms are persistent or disruptive, speak with your GP. Specialist assessment enquiries with Dr Puneet Titoria in Benowa are available using the contact details above.
