Though the flowers are no longer blooming and the air has turned crisp and cool, many allergy sufferers get no reprieve during the fall months. The allergy triggers might be slightly different, but they can be just as misery-inducing as the flower pollen that fills the air in the spring and summer.
During the fall season, ragweed is the biggest allergy trigger. Though the yellow-flowering weed typically begins pollinating in August, it can linger well into the fall months. about three-quarters of people who are allergic to spring pollen-producing plants are also allergic to ragweed. Ragweed pollen can travel for hundreds of miles on the wind, so even if it doesn't grow where you live, it can still make you miserable if you're allergic to it.
Mold is another culprit, because its spores can easily get airborne. Mold thrives in damp areas, both indoors and outdoors. The piles of damp leaves that line yards and streets in the fall are breeding grounds for mold, as are damp basements and bathrooms at home.
Dust mites -- microscopic, spider-like insects -- are yet another common indoor allergen. They are most prevalent during the humid summer months, but can get stirred into the air the first time you turn on your furnace in the fall. From the air, dust mites can make their way into your nose, triggering sneezes, wheezes, and runny noses.
Steroid nasal sprays are one of the strongest allergy medications.
A trip to the Drs. for bad allergies or sinus infections is always a good idea. Reference: WebMD
