Where Are Spring Allergies Worst?

The mild winter and recent warm weather means spring allergy season is in "full bloom" across much of the nation.

And some places are worse than others, according to a new study released by GlaxoSmithKline, the makers of Flonase Nasal Spray.

They found that Tampa, Fla., Louisville, Ky., and Orlando, Fla., will be hit particularly hard by spring allergens this season. The group rated the 25 cities that are the worst for spring allergies. View the full list.

A survey conducted by the group revealed that many Americans do not know the best ways to treat their nasal allergy symptoms, such as nasal congestion, sneezing and itchy, runny nose.

"Ideally, you should try to avoid allergens, but this isn't always a realistic option, especially when you're surrounded by airborne allergens such as pollen," said Dr. Robert Overholt, an allergist with a private practice in Knoxville, Tenn., and a fellow of the American Academy of Allergy, Asthma and Immunology.

Anti-inflammatory nasal sprays, also known as intranasal corticosteroids, are considered a first-line therapy for nasal allergies, according to the World Health Organization and the American College of Allergy, Asthma and Immunology.

The first step in the management of nasal allergies is avoidance when possible. Dr. Overholt suggests some practical tips, such as:

• When the pollen count is exceptionally high, spend more time indoors, in an air-conditioned room;
• When driving, keep your car windows closed and your air-conditioner on;
• Avoid walks through parks or gardens and hiking through the woods.
