Earlier blooms and high pollen grip U.S. cities now
Tap title to read story
Nashville and other U.S. cities reported earlier spring blooms and elevated pollen levels this week as local stations cited data showing growing seasons have lengthened since 1970 and a recent HouseFresh study ranking cities by allergy severity.
Consequences include record or near-record local pollen counts, increased patient symptoms reported by clinics, and health advisories; experts and data sources warn of sustained high pollen in the coming weeks and recommend monitoring counts.

Why it matters
Early blooms and high pollen counts can trigger allergies. If you live in a city with a longer growing season, you may experience more severe symptoms. Keep an eye on local pollen counts and consult your doctor if needed.
