About 60 million people living in the U.S have allergic rhinitis (hay fever), and one in every three adults in the U.S. lives with a seasonal allergy or food allergy. (1,2)

In this article, we will share interesting seasonal allergy facts and statistics and how Quello Allergy drops can provide lasting relief from allergies.

What are Seasonal Allergies?

Seasonal allergies are allergic reactions triggered by pollen from trees, grasses, and weeds. 

If you have seasonal allergies, you tend to experience symptoms that flare up during certain seasons, such as spring or summer. Some people may also experience an allergic reaction in more than one season.

Allergies can be seasonal or perennial, depending on how frequently they occur. If you have a perennial allergy, your allergy symptoms tend to be year-round. (1) Most people who are allergic to pet dander, molds, or dust mites often have a perennial allergy.

Seasonal allergies are those that flare during a specific season, such as spring, summer or fall. Perennial allergies, on the other hand, are year-round and are triggered by indoor allergens such as dust mites, mold, or pet dander.
