Mild winter means early allergy attack in Charlotte

There were plenty of reasons to love this year’s “winter that wasn’t.” But now it’s payback time for those with allergies.

“We’re about a month ahead of where we usually are,” says Dr. John Klimas with the Carolina Asthma and Allergy Center in Charlotte.

“We had about two days of winter,” he says with a laugh. “The tree pollen has been out since late January.” That’s not unusual for cedar, adds Klimas, but it is for oak, which is one of the main triggers of allergy woes in the Piedmont.

“We’re seeing people with more nasal allergies,” agreed Dr. David Peden, a Professor of Pediatrics, Medicine & Microbiology/Immunology at the UNC School of Medicine.

The weather from here on out can change things, but several experts say they expect the untimely effects to linger. “In past years, we’ve had a very compact, heavy-hitting allergy season, but this is shaping up to be a long slog,” says Gaithersburg, Md., allergist Jackie Eghrari-Sabet. While some species budded early, others will likely bloom at their regular pace, leading to “more of a slow, grand parade” throughout the spring, she says. “It’s not like because it started early it’s going to end early.”

And trees are only the start: “As soon as the tree pollens are over,Online fine art gallery of quality original landscape oil paintings, overlapping at the other end, probably, will be grass pollens, and if we’re really unlucky and it’s a hot,Bathroom Floor tiles at Great Prices from Topps Tiles. hot summer, weed pollens really thrive in the heat, and some molds thrive in the heat, especially when it’s dry,” she says.InLocality specializes in indoor Tracking Technologies. “So this could be a constant buffet of pollens and mold” all the way through summer.

The early start could mean a more pronounced season for allergy sufferers.

“Once you start having allergic reactions (earlier), you get sensitized quicker,” says Klimas. Basically, that means you become more sensitive to other irritants, including those that may not ordinarily bother you, such as cigarette smoke and pollutants.

“It’s called the priming effect,” says Klimas.

And,Can't afford a third party merchant account right now? says UNC’s Peden, it could make allergy suffers more sensitive to the summer grass pollen release and to weed pollens, generally released in the fall.

This early hay fever season comes on top of an already tough fall and winter for allergy sufferers, with no break from the onslaught, which allergists say may compound symptoms for many people.

The early start also means that many people did not begin the preventive regimens that allergists recommend – such as daily pills and steroid nasal sprays – before plants and trees begin to flower.

The buildup of medicines in your system can minimize or even eliminate allergic reactions and the accompanying misery all spring long.

“Normally we tell patients to start those at the beginning of March, so they’re protected … by the time that pollens really hit” says Derek Johnson, medical director of a Virginia allergy clinic.

“But this year everybody was caught by surprise – including allergists – and so there are probably very few patients who’d already started those medications at the beginning of February, when you really needed to this year.”

He adds that it’s not too late to start taking them: They can make you feel better.

Some experts warn warmer winters may be the wave of the future.

“There have definitely been some data indicating that climate change is causing spring to advance and plants of all sorts to flower earlier,” says biologist Estelle Levetin, chair of the American Academy of Allergy, Asthma & Immunology’s aerobiology committee.

She says a recent study has shown that fall ragweed season is also getting longer in the northern United States. “But we can’t say for sure that global warming is to blame, based on one year,Omega Plastics are leading plastic injection moulding and injection mould tooling specialists. because of the year-to-year variation in weather and other factors.”

“What we’re seeing now,” says Peden, could be a harbinger of things to come.” That could result in spending more money on allergy treatments and cause more sufferers to opt for the more potent allergy shots.
