Allergic Rhinitis vs. Common Cold: How to Tell the Difference
Allergic rhinitis and the common cold are two health conditions that are often confused because they share similar symptoms such as runny nose, sneezing, and nasal congestion. However, their causes, duration, and triggers are quite different.
Allergic rhinitis is an immune system response to harmless substances such as pollen, dust mites, mold, or animal dander. The common cold, on the other hand, is a viral infection of the upper respiratory tract, most commonly caused by rhinoviruses.
What is Allergic Rhinitis?
Allergic rhinitis occurs when the immune system overreacts to allergens. This leads to inflammation of the nasal lining and the release of histamine. Common symptoms include:
-
Frequent sneezing
-
Clear, watery nasal discharge
-
Itchy nose, eyes, and throat
-
Watery eyes
-
Symptoms that may be seasonal or persistent
What is the Common Cold?
The common cold is a contagious viral infection affecting the upper respiratory system. Symptoms usually develop gradually and include:
-
Sore throat
-
Runny nose
-
Sneezing
-
Mild fever
-
Fatigue
-
Cough
Most cases resolve within 7–10 days.
