(Medical-NewsWire.com, November 20, 2012 ) San Francisco, CA -- Due to an increase in warmer temperatures, allergies are expected to worsen in next few years, according to a research study.
Researchers at Rutgers University are studying plants grown in chambers that have similar climate conditions as would be found outside, such as carbon dioxide levels, precipitation, and temperature, in the coming years, according to data projected by the Intergovernmental Panel on Climate Change.
“Climate change will increase pollen production considerably in the near future,” said Leonard Bielory, lead researcher on the project a visiting professor at Rutgers, in a prepared statement.
Bielory presented his findings at the American College of Allergy, Asthma and Immunology annual scientific meeting this week.
In the research, Bielory states that in the northeastern United States will surpass a white pollen count counts (the average number of pollen particles in a cubic yard of air during a single day) of 11,412 by the year 2020 and 18,285 by the 2040, possibly as high as 21,735. By comparison, the northeastern U.S. averaged a white pollen count of 8,455 in 2000. Ragweed pollen, for example, has dramatically increased in the central part of the nation from Texas to Canada.
Additionally, according to Bielory’s research, allergy season should start and reach peak levels earlier in the year. For example, in 2000, the beginning date for pollen production was 2000; however, by 2020, that date is expected to begin as soon as March 27. The date for peak pollen production is expected to be around April 9 in 2020, compared to May 2 in 2000. With warmer weather, not only will allergy season begin sooner, it will also extend later into the season.
At present, there are no cures for seasonal allergies that affect an increasing number of people. In general, allergy sufferers use over-the-counter medication to combat the symptoms of allergies while some people get allergy shots. Bielory suggests “allergy sufferers begin long-term treatment, such as immunotherapy, now” so as to reduce their reaction to the increased pollen they will come in contact to in the coming years.
