You may be having a bad air day every day -- and we are not talking about
outdoor air. The indoor air quality in your home may be affecting your health
and the health of your family members.
"Indoor air quality can be worse than outdoor air quality in almost every
case,” says William J. Calhoun, MD, professor of medicine and vice chair of the
department of medicine at the University of Texas Medical Branch in
There are potential sources of air pollution in just about every room of
your house, but don’t despair. The good news is that there are easy,
and affordable, solutions for most of them.
What could be polluting the air in your home? The pollutants that lurk
outdoors can be found indoors as well, where they can and do join forces with
other irritants. Those can include fumes from combustion devices and gas-fired
appliances, not to mention allergens such as pet dander, house dust mites, and
mold, Calhoun says.
Space heaters, ranges, ovens, stoves, furnaces, fireplaces, and water
heaters "release gases and particulates into the air,” Calhoun adds. “There is
also the fairly intense burden of allergens with indoor air quality such as
pets, house dust mites. And perennial (year-long) allergens are 10- to 100-fold
higher indoors than out.”
Bad air can trigger coughing, chest tightness, sore throat, watery or itchy
eyes, shortness of breath, and even a full-blown asthma attack. “If you live in
a home with chronically poor air quality, you can experience frequent
headaches, long lasting colds, and bronchitis as well as
chronic asthma,” says E. Neil Schachter, MD, the medical director of
respiratory care at Mount Sinai Medical Center in New York.
3 Steps to Better Indoor Air Quality
Step 1: Increase ventilation in your house. “We tend to keep our
windows tightly shut in the winter, but flinging open a window is not the
answer,” says Schachter. “Outdoor air contains by-products of gas emissions
from cars and trucks, industrial pollution, as well as dirt and mold.”
Best solution? “Use trickle ventilation, which is a 10-inch high screen with
extra filters,” he says. “It adjusts to most windows and allows fresh air in,
helps escort indoor pollutants out.”
