Experts Predict Potentially Worst Spring Allergy Season in 10 Years for 2012
Some experts are predicting that spring of 2012 has the potential to be the worst allergy season in 10 years. Because of a relatively mild winter nationwide, an early allergy season has developed causing many allergy sufferers to begin taking medications earlier than normal.
According to weather experts, nationally, January this year was almost 6 degrees warmer than normal. The typical overall national temperature for January is 30.8 degrees F. However this year it was 36.3 degrees F causing many plants including weeds to begin blooming ahead of Mother Nature’s normal schedule and thereby give birth to an early allergy season.
According to a national news report interview of Dr. Stanley Fineman, President of the American College of Allergy, Asthma and Immunology (ACAAI), last year pollen counts were in the single digits and usually don’t begin to pick up until after February 20. However, this year pollen counts jumped up right after Ground Hogs’ Day on February 2nd with pollen counts some days reaching as high as 250.
“It has been a significantly temperate winter and when we see that, in the United States, we expect that the spring season is going to be very different than what we usually experience,” says Allergist Janna Tuck, MD, an ACAAI board member. “Pollen season is going to occur early, so we will see that the spring tree season will start early and as a general rule the pollen counts will be higher—so patients who are allergic and have spring problems will probably have more problems [this year].”
Dr. Tuck explains that it’s not so much that the trees will necessarily bloom earlier since blooming is largely controlled by daylight exposure with warming temperatures, but that when the trees do bloom they may release more pollen than normal due to the mild winter conditions—especially when preceded by adequate rainfall.
However, she believes that mold might be more of a significant problem for allergy sufferers due to a combination of the mild winter, changing weather patterns and farmers tilling their fields earlier than normal—all of which bring increased levels of mold across the nation.
“In the spring you see more variability [with mold] because of the rains and the mold spores are carried on the weather patterns. And so when a weather front moves through your area, it carries more mold spores to you. And when the farmers till up the land they release a lot of mold into the air,” she says.
Dr. Tuck points out that weather conditions from the previous fall can affect mold counts and types in the spring. As an example she refers to the heavy rains that caused flooding in the Mississippi that resulted in a lot of vegetation being killed off that has been decomposing.
“We do know that there is a change in the mold content from all of the dead and dying vegetation from last year—we are going to have more problems this year as a consequence of the flood from last year,” says Dr. Tuck.
When asked about who in particular should expect to be affected this spring, she believes that the pollen allergy sufferers will likely be harder hit than mold sufferers who tend to be more variable in their response and therefore are harder to predict. The pollen sufferers can expect to see a rougher allergy season ahead of them if no late winter cold snaps hit their regions and if spring rains bring abundant water to the trees, followed then by the grass and weeds in late spring.
