As people begin to break out their fall decor, doctors are warning that candles are among the hidden air-quality dangers inside a home.
Dr. Meave MacMurdo, a pulmonologist at the Cleveland Clinic, says burning candles and other tasks done at home, including cooking and vacuuming can add to a home's poor air quality.
MacMurdo says smoke, vapors, mold and chemicals used in certain paints, furnishings and cleaners can also impact air quality.
Doctors say breathing unclean air is linked to asthma, a higher number of emergency room visits for breathing and heart problems, and increased hospital stays for illness, such as pneumonia and bronchitis.
People can minimize indoor pollution by turning on the vent hood when cooking, avoid burning candles and reduce the amount of smoke coming from wood-burning fireplace.
People should also consider purchasing an air purifier.
