"Rising Pollen Allergies: Cities Facing Longer and Worsening Allergy Seasons"
Spring allergy seasons are starting about 20 days earlier than in the past, with pollen concentrations rising about 20 percent nationwide since 1990, attributed to warmer temperatures, higher carbon dioxide concentrations, and increased precipitation. This shift can have significant health consequences, leading to higher prevalence of allergic rhinitis and longer periods of pollen production. Experts advise being vigilant for allergy symptoms and having medications on hand to manage the worsening allergy season.
