An “allergy” is your immune system’s sensitivity to an otherwise harmless substance. Symptoms such as sneezing, an itchy nose, a runny or stuffy nose, and watery eyes, are examples of your body’s attempts to eliminate an allergen. Typically, allergens can include substances like pollen, dust mites, pet dander, and mold. Seasonal allergies appear during different times of the year and peak in the spring, when most plants are blooming and releasing more pollen. Pollen can be a very difficult allergen to manage, due to its ubiquitous presence in our environment.
