Christmas Trees Cause Increase in Asthma?

What's next - tell me there's no Santa?

A few years ago our family made the switch to an artificial Christmas tree. Mainly I was tired of finding pine needles in my carpet in June. Although I had become somewhat of a scruge. I no longer wanted the hassle of hunting through the tree lots for the perfect tree, hauling it back in our minivan (which of course had to be cleaned out afterwards) and the endless turning trying to find the best side once in our living room.

I felt reassured in my decision when I read an article this week linking live Christmas trees to an increase in asthma and sinus problems.

The study, which was presented at The American College of Allergy, Asthma & Immunology Annual Scientific Meeting in Dallas, examined the relationship between mold growth on live Christmas trees and poor indoor air quality.

This study grew out of a consistent and dramatic increase in asthma and sinus complaints among patients every winter, which is especially pronounced during the holiday season, notes study researcher John Santilli, MD."As mold growth is common in the area surrounding outdoor foliage, we hypothesized that the presence of a live Christmas tree may be contributing to indoor mold," he says.

Indoor Mold Levels Rise Twelve times during a two week period, researchers measured mold counts in a room containing a live Christmas tree, beginning when the tree was brought inside and decorated. The tree was located 10 feet from a heat vent, and the indoor temperature was maintained at between 65 and 68 degrees.

For the first three days, counts remained at 800 spores per cubic meter of air, then began escalating, rising to a maximum of 5,000 spores per cubic meter by day 14, when the tree was taken down.Mold allergy affects up to 15 percent of the population, according to Santilli, and people with sensitivity to certain molds commonly experience nasal, eye, and throat irritation; nasal stuffiness; and headache.

Additionally, there is a well-documented link between asthma attacks and molds, and the added risk of invasive fungal disease among people with compromised immune systems.Santilli says normal indoor air has a mold level of 500-700 spores per cubic meter; anything higher indicates a source of mold growth inside the building."

Ventilation systems and water-damaged areas have long been recognized as sources of mold, but we need to continue to search for new and unique sources of contamination," Santilli says.Avoiding Indoor Mold "Our study demonstrates that a live Christmas tree can be a significant source of mold spores. Therefore, we recommend families with allergies in general and mold allergies in particular not keep a live Christmas tree in their homes for more than a few days at most, and remove it sooner if there are signs of increased allergy symptoms," Santilli says.

Rebecca Gruchalla, MD, PhD, chief of allergy at the University of Texas Southwestern Medical School in Dallas, says the relationship between live Christmas trees and a rise in indoor mold spores comes as no surprise, particularly since most Christmas trees are cut well in advance of the holidays and stored in a moist environment before being placed on a lot for sale. Then they're then taken home and placed in water too, she says. Gruchalla notes that artificial trees and ornaments collect dust in storage and, therefore, are another source of allergy irritation.

She suggests taking both live and artificial trees outside and shaking them out before bringing them inside to decorate.

Just when I had it all figured out, a colleage in San Diego provides the following information for your consideration.

Fake Trees are even worse...

Most fake trees, made from non renewable petroleum also eventually wind up in landfills and are clogging mother earth with PVC (polyvinyl chloride), which is being banned by many medical associations and considered poison to environmentalists. That's why you'll see a label on faux Christmas trees cautioning you to avoid inhaling or eating any bits of lead dust that may fall from the "branches." Fake trees cannot be recycled. When they are disposed of in a sanitary landfill, they will not disintegrate, but will remain there forever, taking up increasingly scarce landfill space. When a fake tree catches fire, it puts dangerous toxic fumes into the air. Fake trees are manufactured mainly outside of the United States and often by companies in china that do not observe high environmental standards.

I'm SOOO confused!

Be assured that whatever type of tree you have this season, Partners In Grime will be there for you before and after the holiday season to get you ready and clean you up afterwards.
