For many allergy sufferers, allergies flare in the fall season. Since allergies are so multifactorial, sometimes it can be difficult to pinpoint a cause.
Common environmental causes of fall allergies include molds, ragweed pollen, smoke particulates from wood burning fireplaces, pet dander, agricultural dust and household dust-mites. With pollen allergies, it is recommended to keep your windows closed. However, with household allergies, irritants can get trapped inside the home and recirculate, so good ventilation is important. Making matters worse, most heating systems tend dry out the sinuses, increasing vulnerability to irritants.
