D.C. is tied for 10th place in the list of Metro areas with the biggest ragweed problems, according to a new study. Ragweed is a source of pain for many allergy sufferers.
The D.C. area is in the top 10 for ragweed allergies, according to a new report put out by quest diagnostics health trends, and the report says the problem is getting worse.
Researchers believe there is a link to climate change. They believe climate is getting warmer which creates a longer blooming season, and this has led to a spike in the amount of ragweed and mold across the country for the past several years.
In 2009, the blooming season was a full one-month longer than it was in 1995, according to the study. Qwest Diagnostics says it is largest national allergy study ever conducted, with more than 2 million subjects.
