Doctors says the Polar Vortex is partially to blame and has causes a "Pollen Vortex."
The prolonged freezing temperatures we had may have delayed the blooming of trees, and now the warm weather has caused trees to bloom at the same time as grasses, causing a dramatic rise in pollen, allergy experts said to Fox News.
Pediatrician Lolita McDavid says, "People who may have both tree allergies and grass allergies are probably going be doubly impacted, because both of those things are going to be blooming at the same time."
The CDC says about 8 percent of U.S. adults suffer from seasonal allergies, including stuffy and runny noses, watery and itchy eyes, sneezing, and wheezing, especially on days with high pollen counts.
"The allergy seasons seem to be getting intense in the last few years. We are not quite sure why," McDavid said. "We don't know if it's the climate change. It may be."
Also, heavy rains temporarily suppressed pollen release, while encouraging the growth of trees and grass, resulting in greater pollen release later in the season, experts say.
It's a good idea to change your clothes when you get home to keep the pollen out of the house. And wash your hands. Close the windows and turn on air conditioning to keep pollen out.
Try taking an antihistamine before bed, to help prevent allergic reactions for 24 hours.
