"As you move north, the change is that it starts earlier and ends later. What does it correspond to? Frost-free days," Bielory said.
Warming temperatures increase the number of frost-free days. His research also revealed humans experienced increased allergy sensitivity because of enhanced exposure. "Ragweed sensitivity used to be about 40 percent about 25 years ago. It is now approaching 60-70 percent of the population," Bielory said."Pollen counts will increase, meaning the amount of pollen a single plant produces will increase and the duration that it's releasing the pollen will increase," he said.Dr. Katherine Monteleone, professor of medicine at Rutgers RWJ Medical School says at the first sign of symptoms, activate avoidance measures and start medicine.
"Windows closed, home and car. Air conditioner can filter," Monteleone said."The other thing is outdoor clothes and indoor clothes. Pollen gets to you because it sticks to the mucosa of your eyes, your nose. It can also stick your clothes and your hair.""A lot of people who suffer find that just doing that helps them use less medicine," Monteleone said.
