Causes of a Runny Nose

The leading cause of a runny nose is a blocked nasal cavity due to a cold or another upper respiratory tract infection. However, many other things can cause a runny nose.

   Viral Infections: Colds and flu are caused by a viral infection. A runny nose is one of the symptoms of a cold or flu. When you have a cold, your body’s defenses fight back, and this can cause your nasal passages to swell, trying to sweep out the infection.

   Allergies: This can also cause your nose to run. For instance, you may notice a runny nose if you have allergies to pollen, dust, or mold and are exposed to these allergens. Allergies can irritate the nasal passages, causing you to sniff and sneeze. This may cause your nasal passages to swell, allowing the fluid to leak out.

   Nasal Polyps: These are finger-like protrusions inside your nose that form in response to inflammation.

   Dry Air: When your environment has very dry air, you can also experience a runny nose. Dry air can irritate the sinuses, causing you to sneeze, and your body responds to it by trying to increase the moisture in your nose.  Lets look 4 highly effect methods to stop a running nose…
