What Causes a Runny Nose?

A runny nose can often be a sign of allergies. When you’re exposed to common allergens such as pollen, dust mites, pet dander, or mold, your immune system may react by releasing chemicals like histamine. This reaction can cause inflammation in the nasal passages, resulting in symptoms like a runny nose, sneezing, nasal congestion, and itchy eyes or throat—collectively known as allergic rhinitis or hay fever.

However, a runny nose can also be caused by other factors, including infections, irritants, or even weather changes. It’s important to pay attention to when and where your symptoms occur. If your runny nose is persistent, appears in specific environments, or is accompanied by other allergy-related symptoms, it may be time to seek professional help.

Our experienced healthcare providers at our urgent care can help you identify the cause of your symptoms and develop a personalized treatment plan. We offer comprehensive allergy testing and management options to help you find relief and improve your quality of life. If you’re struggling with persistent nasal symptoms, schedule an appointment with Nova Medical Group for expert evaluation and care.

At Nova Medical Group, we often see patients with concerns about runny noses, especially during seasonal changes. Yes, changes in the weather can absolutely trigger a runny nose, and understanding why can help you manage your symptoms more effectively.

When the temperature drops or the air becomes cold and dry, the lining of your nasal passages can become irritated. Your body responds by producing more mucus to keep your nasal tissues moist and to trap any particles or pathogens you might breathe in. This extra mucus often results in a runny nose.

Moving between warm indoor spaces and chilly outdoor air can also cause “cold-induced rhinitis,” where the blood vessels inside your nose expand and stimulate additional mucus production. Additionally, weather changes can stir up allergens such as pollen, mold, or dust, which may further irritate your nasal passages.

Most runny noses caused by weather changes are harmless and temporary. However, it’s important to know when symptoms might signal something more serious. If your runny nose persists, worsens, or is accompanied by other concerning signs – such as fever, sinus pain, or thick green or yellow nasal discharge – our providers at Nova Medical Group are here to help. We can evaluate your symptoms, determine the cause, and recommend appropriate treatment.

At Nova Medical Group, we frequently see patients experiencing the bothersome symptoms of the common cold, including a runny nose. This symptom is usually caused by a viral infection, such as the rhinovirus. When the virus enters your body—typically through the nose or mouth—it begins to infect the lining of your nasal passages.

Your immune system quickly recognizes the invading virus and, in response, sends white blood cells to the area to fight the infection. This immune activity leads to inflammation in the nasal tissues, causing swelling and increased blood flow. As a result, the glands in your nasal lining produce more mucus than usual to help trap and flush out the virus and other irritants.

This process leads to the familiar symptom of a runny nose. The inflamed and swollen nasal passages become less effective at reabsorbing fluid, causing even more mucus to drip out. While this can be uncomfortable, it is actually your body’s natural way of clearing out the infection and protecting your respiratory system.
