If so, you are not alone. Millions of Americans sniffle and cough their way through the fall allergy season. The most common allergen during the fall is ragweed. Ragweed pollens are microscopic and can travel 300 to 400 miles through the air. This means that even if there is no ragweed in your yard, it can still wreak havoc on your allergies.
Russian thistles are also common allergens in the fall.
Molds can also cause problems for allergy sufferers, especially in the South where they grow year-round. Dust allergies may be more problematic in the fall and winter since your doors and windows stay closed, trapping dust indoors. The best thing to do, of course, is to avoid the allergen, but this is not very realistic. Run an air conditioner to keep humidity low. If these tips do not help, visit an allergist to discuss your treatment options.
