10 Reasons You Have a Runny Nose

Hay Fever

Seemingly more prevalent than pet allergies are pollen allergies, typically known as hay fever. Hay fever is in play from spring through fall, as trees, weeds and grasses emit miniscule pollen grains into the air. Everyone breathes in some of these grains, and for most people it's no big deal. But if you're allergic to a particular type of pollen, you'll have an allergic reaction.

As with pet allergies, symptoms include a runny nose, sneezing, coughing and itching in the eyes, nose and throat. Post-nasal drip is also common, as are dark circles under the eyes.

Try to relieve your symptoms by rinsing out your nasal passages and taking over-the-counter medicines recommended by your doctor. Allergy shots also may be helpful. Sidebar: Are Nasal Sprays Really Addictive?

The short answer is no, but they're not harmless either. You candevelop what's called a rebound effect: If you use the spray too many days in a row, your body panics and begins to work against it, which means it soon takes more sprays, or more frequent sprays, to clear your nose. It could take a few weeks to a month or so of not using the spray to return to normal.
