Allergies are one of the most common chronic diseases. They occur when our bodies see a substance as harmful and overreacts to it. Seasonal Allergic Rhinitis generally involves allergies to pollens and molds. Perennial Allergic Rhinitis generally involves allergies to dust mites and animal dander. Although these allergy symptoms are not life-threatening, they can cause debilitating symptoms reducing one's quality of life.
