According to the American Academy of Allergy, Asthma and Immunology (AAAAI, "quad-A-I" as it sometimes called), there are 35 million people affected by allergies in the U.S. This year's weather does not make their life any easier. The lack of rain has lead to an increased amount of pollen in the air.

Pollen levels are graded as low, high and extreme high, and this year many extreme highs were recorded according to Dr. Timothy Craig of Penn State Milton S. Hershey Medical Center.
