10 Worst Cities for Allergies and Why
8. Providence, Rhode Island

Although the American Academy of Allergy, Asthma and Immunology doesn’t even have a pollen counter located in the city of Providence, it’s still considered to be a dangerous place for allergens. According to climate experts, the temperatures in the city keep rising. This makes it easy for plants to thrive and eventually for pollen levels to increase. It has a current ranking of lower than average number of allergists available. You can reduce the amount of pollen brought into your home by going with hard wood floors over carpet.
7. 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. It has been in and out of top 10 lists for years. But springtime allergies can be a concern for sensitive people with allergies as springtime is 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 you to vacation during this time.
