HOUSTON, Texas – Cedar fever is officially back in Houston as mountain cedar pollen levels surge across Southeast Texas.
Pollen counts increased sevenfold by Thursday, reaching the “very high” range and triggering allergy symptoms for many residents.
This seasonal spike happens every winter and is closely tied to cold fronts moving across Texas.
Mountain cedar trees, also known as Ashe junipers, grow by the tens of millions in the Texas Hill Country, where the limestone soil and hilly terrain create ideal conditions for pollen production.
When cold fronts sweep through the state, strong winds kick up the pollen and carry it hundreds of miles east into the Houston area.
Cedar pollen is especially problematic because Houstonians are only exposed to it for a short period each year.
According to allergy specialists, limited exposure doesn’t allow the body enough time to build natural tolerance, even for people who have lived in Texas their entire lives.
As a result, mountain cedar pollen can cause severe symptoms, including congestion, sneezing, itchy or watery eyes, sinus pressure, sore throat, and fatigue. Symptoms often feel like a cold or flu, but without a fever.
Doctors recommend staying ahead of symptoms by taking allergy medications consistently throughout cedar season, rather than waiting until symptoms become severe.
Antihistamines, nasal sprays, and eye drops are most effective when used daily.
Experts also advise limiting outdoor exposure on high-pollen days, keeping windows closed, showering and changing clothes after being outside, and using HEPA air filters indoors to reduce pollen buildup.
With several additional cold fronts expected, allergy specialists warn pollen levels could continue to rise in the coming weeks.
The good news is that cedar season in Southeast Texas is typically short-lived and usually wraps up by early March, bringing relief for allergy sufferers.
