Autumn brings cooler nights, changing leaf colors — and seasonal weed and mold allergies.
If your fall allergies seem worse than ever, chances are you are not wrong.
Ragweed, the main culprit in fall weed allergies, has not only been expanding in population size, but also in the length of its season due to changing climate conditions.
And then there’s mold, which thrives in damp piles of autumn leaf litter, releasing spores that float through the air and cause wheezing, runny noses, watery eyes and rashes or hives in people allergic to the fungal cells.
Mansoor Amiji, a Northeastern University distinguished professor of pharmaceutical sciences and chemical engineering, says the first line of defense is the same as with tree allergies in spring and grass pollen allergies in summer — treat the symptoms.
