Ragweed and mold are driving increased allergies across America, Quest Diagnostics reported Monday.

Patients with seasonal allergies are more likely to experience difficulty sleeping, according to results of a new survey conducted by Teva Respiratory.

Whoever named the genus to which ragweed plants belong “ambrosia” had a terrific sense of irony. The name, derived from Greek, refers to the food of the gods, but the plant is more like punishment from the gods, considering that it’s the main culprit in seasonal allergies.

A U.S. Department of Agriculture study published in March in the journal Proceedings of the National Academy of Sciences has found that ragweed season is almost 16 days longer than it was in 1995 due to changes in the first frost line of the fall in North America. The first frost steadily has been creeping northward and later into the year, lead researcher Lewis Ziska wrote. That’s 16 more days of allergy relief sales — especially good news for Chattem as it shepherds its recently switched Allegra antihistamine through its first year.

In a sneeze heard around the world, allergy season is afoot, but the country’s retail pharmacies are on call to help the estimated 60 million Americans whose sneezing, coughing, watery eyes and congestion will drive them to wit’s end this year.

This weekend, Sam's Club is offering free allergy health screenings in select locations across the country.
