Are you one of the many unfortunates who requires seasonal allergy treatment year after year? Allergic reactions occur when your body thinks it's fighting off harmful invaders, like bacteria and illness, but what ends up happening is it reacts too strongly – producing symptoms like a runny nose, sneezing, hives, and so forth. Because these symptoms are similar to those of a cold or flu, many people don't realize they have seasonal allergies, thinking instead that they have a stubborn illness. Instead, seasonal allergies are brought on by environmental triggers that are most prevalent during a particular season, like pollen, grass, oak, and so forth.
