A recent study blames climate change for worsened seasonal allergies within the U.S. per reports from the University of Utah and the American College of Allergy, Asthma, and Immunology. The report suggests that because of warmer temperatures and the amount of carbon dioxide in the air, plants and molds are producing more pollen or spores and in turn triggering earlier starting and longer allergy seasons.
Some allergists also suggest that pollutants are also significantly contributing to individuals' responses to environmental allergies as greenhouse gases and air quality mingle to irritate mucus membranes and nasal passages. Many experts have found that people living in portions of the U.S. where air pollutant levels are high
are more likely to suffer from allergies. In fact, as Richard Weber of the National Jewish Health Center and the American College of Allergy, Asthma and Immunology stated in a recent interview, not only do people in "heavy traffic routes [have] higher rates of being allergic," but also "we are experiencing longer allergy seasons, earlier onset, and there is just more pollen in the air."
Thought there is no way to absolutely predict just what to expect this year, most experts agree that 2013 may be the worst for people who suffer from seasonal allergies particularly for those in the Northeast, West, and other regions of the United States.
