Many unaware of allergies to ragweed

LOS ANGELES (KABC) -- Those who find themselves sneezing a lot lately may not realize they are having an allergic reaction to ragweed.

Dr. Katie Marks-Cogan said many people mistake a ragweed allergy for a cold that just won't end because they don't realize allergies are more than just sneezing and itchy, watery eyes.

"Atypical symptoms like sleep deprivation and general fatigue and even a decrease in concentration can be caused by a ragweed allergy," she said.

One ragweed plant can produce up to 1 billion grains of pollen every season. Doctors say the pollen spread increases because of higher concentrations of carbon dioxide and warmer temperatures.

Symptoms can be managed with over the counter antihistamines and daily nasal rinses, or doctors can prescribe stronger medications if needed.

Cogan recommends keeping windows closed when pollen counts are highest, which happens between 10 a.m. and 4 p.m. She also recommends changing clothes right when you get home.

Other advice to ease symptoms is to take a shower. Pollen is sticky and can be difficult to get out of hair. For those who have pets, make sure to wipe down their fur when they come back in the house after being outside.
