Weather events worsen allergies

Climate changes lengthening season

There may be a whiff of truth to claims by allergy sufferers who sniffle that this season is, well, a bigger headache than years past.

And now, more bad news: It’s also lasting longer, prolonging the misery of the millions of people for whom spring is a punishment, not a pleasure.

Heavy snow and rain in some parts of the country have nourished a profusion of tree pollen, while a sudden shift to warm, sunny weather has made its release more robust. The deluges and, in some places, flooding have pumped up the volume on mold. Add in the wind, and the suffering skyrockets.

Warnings about the difficult season have come from allergy specialists from New York to Atlanta, Chicago to California.

“This past week has been one of the worst ever,” rasped Lynne Ritchie, 70, as she bought allergy medicine this week at a Manhattan drugstore.

Dr. Stanley Schwartz hears that from patients all the time – every year, in fact, he noted with a wry smile.

“Literally, every year is the worst year,” said Schwartz, chief of allergy and rheumatology for Kaleida Health and the University at Buffalo. “Now it may actually be, but when it’s there and you’re feeling it, you don’t remember what last year was like.”

What is certain is that allergy seasons in general have been getting longer and more challenging, said Angel Waldron, spokeswoman for the Asthma and Allergy Foundation.

“We do know that climate change and warmer temperatures are allowing trees to pollinate longer than usual,” she said. “Although people feel things are worse than ever before, it’s actually because of the longer season. It’s a longer time to endure.”

Pollen counts and allergy attacks vary widely from region to region, locality to locality, and day to day, and no single entity tracks the full complexity of their ups and downs across the country. But everything is ripe this year for a historic season.

It’s been an exceptionally rainy spring in much of the country, with several states east of the Mississippi River setting records for the wettest April since 1895. That means luxuriously blooming trees and a similar effect on mold.

“The mold will grow under the fallen leaves from last season,” Schwartz said. “So if it’s very wet, it isn’t just the blooming plants but it’s also the mold, and many people are allergic to multiple airborne allergens.”

The highest tree pollen count in three years triggered a dangerous air quality warning Friday in Chicago, where allergist Dr. Joseph Leija warned in a statement: “Itchy eyes, stuffy noses and fatigue will be common among Chicagoans with sensitive respiratory systems.”

In Los Angeles, rain, a heat wave and the Santa Ana winds combined for a brutal stretch in February. To the north in San Jose, pollen counts are on the rise with the start of grass season, allergist Dr. Alan Heller said Friday.

The National Allergy Bureau shows high pollen counts in the Northeast this week, including Albany and New York City, with their birch, oak and maple trees, and Oxford, Ala., where walnut, pine and willows are in bloom.

“It’s been a very bad season so far. … A lot of people suffering,” said Dr. William Reisacher, director of the allergy center at New York-Presbyterian/Weill Cornell Medical Center in New York City.

“A lot of people who haven’t suffered in previous years have come in for the first time in several years with symptoms,” Reisacher said, noting that the Northeast’s sudden change from cold, snowy winter to warm spring has worsened the situation.

Full circle round, back in the South, the Atlanta Allergy and Asthma Clinic has seen no letup since late February, when unseasonable warmth had Dr. Kevin Schaffer describing this year’s pollen levels as “off the charts.”

Medications used in the past may not be as effective if symptoms are worse this year, Reisacher said. Many of his patients in New York have required multiple drugs, including nasal sprays, oral antihistamines and eyedrops.

In Dallas, a windy spring is helping to scatter the allergens.

“We’ve had heavy winds and the tree pollens were in heavy bloom, and all the wind was causing a lot of people a lot of problems,” said Jill Weinger, physician’s assistant at the Dallas Allergy & Asthma Center, where some patients were returning for treatment after years of absence.

In Louisville, Ky., 20-year-old Jared Casey’s glazed eyes scanned the aisles of a Walgreens drugstore Thursday afternoon. He greeted the allergy season with an over-the-counter purchase of Claritin-D at the beginning of February – six weeks earlier than last year.

Kristen Fennimore, of New Egypt, N.J., counts herself among the more than 35 million Americans plagued by seasonal allergic rhinitis – also known as hay fever, a condition characterized by sneezing, stuffiness, a runny nose and the telltale itchiness in the nose, roof of the mouth, throat, eyes or ears.

Until recently, the 28-year-old legal assistant said, she was feeling pretty good and thought she might get off easy this year. But pride goes before a fall.

“I was going around bragging how my allergies weren’t bad this year,” she said. “Then this week, it’s been horrible.”
