If it seems like your allergy symptoms are never ending, there may be an explanation.

The allergy season, which use to run from mid-August to September, could be getting longer. In many parts of the country, symptoms such as itchy eyes and stuffiness are starting earlier and extending through October.

According to the American Academy of Allergy, Asthma and Immunology, the main culprit is an extended growing season for the ragweed plant. Research suggests rising temperatures and higher carbon dioxide levels are helping allergen producing plants hang around longer.

The group recommends avoiding the outdoors when pollen counts are extra high.
