DALLAS, Sept. 12 /PRNewswire-USNewswire/ -- If you're one of the millions of Texans who suffers through the misery of fall allergies, hold on to your handkerchief: Allergy researchers at Presbyterian Hospital of Dallas say the upcoming ragweed season could be the worst in decades.
"The unusually wet weather this summer means ragweed plants are big and healthy, and that's bad news for lots of people," said Gary Gross, MD, an allergist at Presbyterian Hospital of Dallas. "Ragweed tends to be one of the worst pollens in Texas, and I think this fall could be the worst in recent memory."
Even worse, more congestion means more people who catch colds and flu this fall will have a tougher and longer battle with the viruses. And with congestion and viral bugs come more sinus infections. "I hate to say it, but it's going to be a rough fall for millions of people," Dr. Gross said.
In addition to wet weather this year in many parts of the state, rising global temperatures during the last decade have increased pollination, as ragweed and other plants struggle to survive the harsher conditions. Additionally, higher levels of carbon dioxide in the air help ragweed grow larger and use water more efficiently, according to recent studies.
"Opportunistic plants like ragweed thrive in warm conditions with more carbon dioxide," said Sandeep Gupta, MD, an allergist on the medical staff at Presbyterian Hospital of Dallas. "When you mix in the tremendous amount of rain we've had this summer, things are going to be really bad this fall for allergy sufferers."
Floods swamped numerous parts of the state this year. River banks,
where ragweed traditionally grows, were made fertile from the rushing water
of heavy rains. Swollen rivers that crested their normal banks also created
millions of acres more than normal of the wet, disturbed soil where ragweed
best germinates. Any region in Texas where flooding occurred likely will
have high ragweed counts this fall
