Sinus allergies cause congestion, feelings of pressure, discomfort and pain, and a runny nose. Sinus allergies are often confused with cold symptoms, but are characterized by an itching nose or eyes. According to AllergyReliefCenter.com, there are many causes of sinus allergies, including environmental factors such as dust, pollen, mold and mildew. Determining the cause of a sinus allergy is important for treating, decreasing and preventing symptoms.
Pollen
One of the most common causes of sinus allergy is hay fever, a broad term for an allergic reaction to environmental elements such as pollen and ragweed. This type of allergy normally begins or worsens during the spring when the pollen count is very high, but can occur at any time of the year. Pollen is a powdery substance released into the air by flowers and carried into the body by breathing. The body perceives the pollen as a harmful, foreign substance and overreacts to it, causing allergy symptoms.
Dust, Mold and Mildew
Outdoor and household dust, particularly in carpets, drapes, heavy furniture and ventilation, can also trigger a sinus allergy. Minimizing dust collecting surfaces and installing an air filter in the home can decrease sinus allergies. Like pollen and dust, mold and mildew are also environmental allergens that can cause sinus allergies. Mold and mildew usually occur in damp and dark areas such as basements, showers, underneath sinks, closets and cupboards. They release spores into the air that are breathed into the body, triggering an allergic reaction by the sensitive immune system.
Animal Fur and Dander
Some individuals are allergic to animal fur, dander and even feathers, and have an allergic reaction when they come in contact with common household pets such as cats and dogs--or even visit a home that has a pet. In most cases, it is not the actual animal fur or dander that triggers the allergy symptoms, but the millions of microorganisms that live in the fur of these animals. Sinus allergies due to animal fur and dander are more easily controlled than allergic reactions to pollen because it is much easier to avoid animals and households with pets.
Household Chemicals
Synthetic and chemical pollutants from household cleaning supplies, laundry detergents, paints, furniture stains and carpets can also trigger sinus allergies. These chemicals often remain in the air for long periods of time and irritate the immune system when they enter the body. Removing carpets, using chemical-free cleaners and laundry detergents, using air filters in the home and having household plants can help improve the quality of indoor air.
