There has been one positive from the Arctic chill that gripped
North Texas this week.
The deep freeze held off the annual invasion of mountain cedar,
the winter pollen that blows in and makes many allergy sufferers miserable,
with steady sneezing, itchy eyes and scratchy throats.
While pollen counts have been mostly nonexistent during the recent
freeze, once things warm up it probably won’t take long for mountain cedar
sufferers to start sneezing again.
“This hard freeze will make the pollen release,” said Dr. Shelly Harvey,
an allergist who practices at the UT Southwestern
Monty and Tex Moncrief Medical Center in Fort Worth.
Through Friday, mountain cedar had yet to make a return to North
Texas, according to pollen counts. But there were moderate counts in Georgetown
and heavy counts in San Antonio, where juniper trees — the producer of mountain
cedar — are plentiful.
Locally, mountain cedar counts can soar on warm, windy days —
often ahead of a cold front — when pollen blows in from Central Texas and the
During last year’s winter pollen season, mountain cedar showed up
on Jan. 8 and was present for
all but two days the rest of the month.
With temperatures expected to climb into the low-60s this weekend,
North Texas could see a blast or two of mountain cedar. But there’s also a
chance of rain, which could wash the pollen out of the air.
University of Tulsa biology professor Estelle Levetin studied the transport of mountain cedar pollen for
17 years, including once tracking it all the way from Texas to Canada.
She previously told the Star-Telegram that it needs to be 50
degrees or higher for the juniper trees to start pollinating, Other issues,
such as humidity and sunlight, can also play a role in whether a tree
On Christmas Eve, there was a moderate concentration of pollen in North
Texas but counts plummeted when the cold temperatures arrived. “If people know they’re
allergic to mountain cedar, it would be a good idea to start a nasal steroid
spray, then add an antihistamine as symptoms develop,” Harvey said.
But if the symptoms persist, Harvey said allergy sufferers may
need to see an allergist and get tested, which could ultimately lead to allergy
Coping with mountain cedar
For those with severe mountain cedar allergies, these steps have
been recommended by some allergists:
▪ Keep windows closed at home during the pollen season,
especially on windy days.
▪ Keep the home dusted — but the person who is allergic
should not do the dusting.
▪ Always shower immediately after working outside or
spending time outside. This will help get the pollen off your skin and out of
▪ Wear close-fitting or “wraparound” sunglasses to
reduce pollen in the eyes. Use artificial-tears eye drops to wash away the
▪ If you have allergies, take prescribed antihistamines
and nasal sprays daily during the allergy season. They work much better to
prevent allergy symptoms before they start than after.
