What Causes Allergies?

Allergens lead to allergies.

Allergens are specific proteins that can trigger an inappropriate immune response or allergy in susceptible people.

Common indoor sources of allergens include cats, dogs, dust mites, cockroaches, mice, pollens and mold.

Why do allergens matter?

Asthma occurs as a result of repeated inflammation of the airways, related, in part, to exposure to both indoor and outdoor allergens.

Asthma is one of the most common chronic illnesses for all age groups, and reducing repeated exposure to indoor allergens can help reduce asthma rates.
