Spring allergies are back. Here's how to check pollen levels and keep from sneezing

ATLANTA — Allergy season can be miserable for tens of millions of Americans when trees, grass, and other pollens cause runny noses, itchy eyes, coughing and sneezing.

Where you live, what you're allergic to and your lifestyle can make a big difference when it comes to the severity of your allergies. Experts say climate change is leading to longer and more intense allergy seasons, but also point out that treatments for seasonal allergies have become more effective over the last decade.

Here are some tips from experts to keep allergy symptoms at bay — maybe even enough to allow you to enjoy the outdoors.

Where are pollen levels the worst this year?

The Asthma and Allergy Foundation of America issues an annual ranking of the most challenging cities to live in if you have allergies, based on over-the-counter medicine use, pollen counts and the number of available allergy specialists.

This year, the top five cities are: Wichita, Kansas; New Orleans; Oklahoma City; Tulsa, Oklahoma; and Memphis.

Which pollens cause allergies?

There are three main types of pollen. Earlier in the spring, tree pollen is the main culprit. After that grasses pollinate, followed by weeds in the late summer and early fall.

Some of the most common tree pollens that cause allergies include birch, cedar, cottonwood, maple, elm, oak and walnut, according to the Asthma and Allergy Foundation of America. Grasses that cause symptoms include Bermuda, Johnson, rye and Kentucky bluegrass.

How do I track pollen levels?

Pollen trackers can help you decide when to go outside. The American Academy of Allergy Asthma and Immunology tracks levels through a network of counting stations across the U.S. Counts are available at its website and via email.

Limit your exposure to pollens

The best and first step to controlling allergies is avoiding exposure. Keep the windows in your car and your home closed, even when it's nice outside.

If you go outside, wearing long sleeves can keep pollen off your skin to help ward off allergic reactions, said Dr. James Baker, an allergist at the University of Michigan. It also provides some sun protection, he added.

When you get home, change your clothes and shower daily to ensure all the pollen is off of you — including your hair. If you can't wash your hair every day, try covering it when you go outside with a hat or scarf. Don't get in the bed with your outside clothes on, because the pollen will follow.

It's also useful to rinse your eyes and nose with saline to remove any pollen, experts said. And the same masks that got us through the pandemic can protect you from allergies — though they won't help with eye symptoms.

How to relieve allergy symptoms

Over-the-counter nasal sprays are among the most effective treatments for seasonal allergies, experts said.

But the vast majority of patients use them incorrectly, irritating parts of the nose, said Dr. Kathleen Mays, an allergist at Augusta University in Georgia. She suggested angling the nozzle outward toward your ear rather than sticking it straight up your nose.

Over-the-counter allergy pills like Claritin, Allegra and Zyrtec are helpful, but may not be as effective as quickly since they're taken by mouth, experts said.

Experts also said that if your allergy symptoms are impacting your quality of life, like causing you to lose sleep or a lack focus at work or school, it might be time to consider an allergist appointment for immunotherapies.

Some remedies for allergy relief that have been circulating on social media or suggested by celebrities — like incorporating local honey into your diet to expose yourself to pollen — have been debunked.

Dr. Shayam Joshi, an allergist at Oregon Health and Science University, said that's because the flowers that bees pollinate typically don't contain the airborne pollen that causes allergy symptoms.

Is allergy season changing?

With climate change, winters are milder and growing seasons are longer, meaning there's more opportunity for pollen to stay in the air, resulting in longer and more severe allergy seasons.

In many areas across the country, pollen counts have broken decades of records. In late March, the Atlanta Allergy and Asthma Center measured a pollen count of over 14,000 grains per cubic meter, which is considered extremely high.
