ALLERGY BASICS

What are allergies?

An ‘allergy’ is a sensitivity of your immune system to something that is ordinarily harmless. When your body tries to get rid of the ‘allergen’ (foreign substance), you experience symptoms like sneezing, itchy, watery eyes, and a runny, stuffy nose. Typical allergens include pet dander, pollen, dust mites, and mold.

Outdoor: Seasonal Allergies

Seasonal allergies describe allergies that change with the seasons due to pollen from plants. These allergens can be difficult to manage because it seems like they’re everywhere and they’re difficult to avoid. For people with seasonal allergies, symptoms come and go with the pollination seasons of certain trees, grasses or weeds. Pollen levels from these plants can vary day to day, depending upon several factors, including the weather. High pollen levels can, in turn, affect the severity of symptoms.

Indoor: Year-Round Allergies

Indoor allergies can occur any time of the year and are caused by substances like dust mites, mold spores, or pet dander. These allergens can be difficult to manage, especially since they tend to exist in our homes year-round. Since you’re often indoors during winter, household allergens like molds, dust mites, and pet dander can be troublesome.
