The Absolute Worst US Cities For Allergies And Why

4. Dayton, Ohio

Dayton, Ohio does not hold a strong spot on the list of worst cities for allergies, but its rise in allergy medications keeps it firmly planted on the list, and it has been in and out of top ten lists for years. Springtime allergies can be a concern for sensitive individuals with allergies as springtime is the peak time for tree pollen spikes. Other trees that may cause allergies in Dayton include cedar, beech, juniper, and cypress. These trees won’t let up their pollen content until May, so living here may require vacations during this time. It's time to head to a city in the state where everything is bigger, including the severity of allergies.
