When christmas trees make you sneeze – ThinkHealthy News
Scotch pines and Douglas firs–the Christmas trees most commonly sold at lots–shed more than needles. They also can release allergy-causing mold spores and pollens that collect on them from other trees. (These varieties release their own pollen in the summer.) But mountain cedars, which many people cut themselves, release pollen around the winter holidays. “In certain areas, one in 10 people is allergic to cedar pollen,” says David Khan, M.D., an allergy specialist at the University of Texas Southwestern Medical Center at Dallas. “Most allergy sufferers will do fine around Christmas trees, but people who are bothered by strong odors and some who are allergic to molds may have problems,” Khan adds.
