Introduction
The most common cause is an upper respiratory tract infection, also known as the common cold. In such cases, adequate rest and increased fluid intake are recommended, along with oral medications for symptomatic treatment. Runny nose and sneezing may also occur; this condition is termed allergic rhinitis. It is typically seasonal and characterized by nasal congestion accompanied by frequent sneezing—hallmarks of allergic rhinitis.
We sometimes experience sneezing and runny nose, often accompanied by pharyngitis, cough, fever, and other symptoms. So, what causes sneezing and a runny nose?
What Causes Sneezing and a Runny Nose?
The most common cause is an upper respiratory tract infection—commonly known as the common cold. In such cases, adequate rest, increased fluid intake, and symptomatic oral medications are recommended. According to Dr. Robert A. Sclafani, Professor of Medicine at the University of California, San Diego, another possible cause is allergic rhinitis—a seasonal condition characterized by frequent sneezing, watery nasal discharge, and nasal congestion triggered by exposure to allergens. For allergic rhinitis, avoidance of known allergens is essential. Topical antihistamines (e.g., azelastine) or intranasal corticosteroids (e.g., fluticasone) may be used for symptomatic relief; oral antihistamines can also be prescribed if necessary.
Another cause of sneezing and rhinorrhea is vasomotor rhinitis—a non-allergic condition often triggered by environmental temperature changes or emotional stress. Its primary symptoms include sneezing, clear nasal discharge, and nasal congestion. Unlike allergic rhinitis, allergy testing yields negative results in vasomotor rhinitis.
Management typically involves optimizing the surrounding work environment—especially minimizing exposure to severe air pollution and smog. Maintaining appropriate warmth helps prevent colds, and managing emotional well-being—avoiding excessive stress—is also important.We hope this information is helpful. Wishing you good health and happiness!
