What are allergies?

Allergies 101

Description: 

Allergy sufferers have immune systems that mean well, but are a little over-reactive, releasing chemicals like histamine to get rid of normally harmless substances called allergens.

Histamine triggers the body to push the allergens out, using your nose, eyes, and mouth as exit routes, which creates inflammation and general allergy-related symptoms in the process.

Allergy Causes

Description: 

Allergens cause allergies, and unfortunately, allergens are everywhere. Common allergens include pollen, dust mites, mold spores and pet dander. While there’s no way to completely eliminate allergens, knowing which ones affect you will help you reduce them.

Common allergies tend to fall into two categories: seasonal and year-round. To figure out when you’ll need relief most, check out our seasonal vs. year-round allergy guide.
