Fall allergies can be caused by a number of airborne allergens including pollens, molds and even dust mites. Symptoms of fall allergies are similar to any other seasonal or airborne allergy. These symptoms include itchy eyes, watery eyes, itchy nose, sneezing, coughing, fatigue and sleeplessness. Fall allergies are sometimes unexpected, which is why the Mayo Clinic points out that they are often mistaken for the common cold or sinus infection. Treatment can include medications as well as preventative measures to avoid the allergens.
Ragweed/Pollens
Male plants or parts of plants produce seeds that are sent into the air to pollinate (fertilize) female trees. The pollens often begin in late summer and can carry over into the fall season, says the National Institutes of Health (NIH). Pollens can cause allergic rhinitis, a group of allergy symptoms, as they are introduced into the nasal passages. This happens when airborne pollens attach themselves to the hair, clothing and skin when you go outside. The NIH suggests that certain pollens and ragweed levels can be higher in different parts of the world at different times of the year.
Mold
Mold spores can be found inside as well as outside. Any moist and warm environment can help mold thrive. The spores can become airborne and enter the nasal passages, just like pollens, and cause allergic reactions in individuals with such sensitivities. In the fall, this can be especially problematic with leaf piles that have become wet from rain. The NIH points out that some produce such as mushrooms may produce mold spores in the fall depending on the region. Like plants, the produce pollinate to reproduce.
Dust Mites
Most homes contain dust mites, microscopic insects that belong to the spider family. They thrive in warm and humid environments. When the household heating unit gets turned on in the fall, it can spread the dust mites about the home. Regular cleaning can help control dust mites but if you have dust allergies, more intensive cleaning is important.
