Answer:
“The residual gas and particles from cigarette smoke that settle pose health hazards, particularly in rooms with a lot of fabric or carpeting,” says pulmonologist Sumita Khatri, MD. “We all have heard of second-hand smoke; this is called third-hand smoke.”
She says the risks are disproportionately high in children, who are more likely to be playing on the ground, and in people with chronic heart and lung problems.
Electronic cigarettes are a similar source of pollution to consider, Dr. Khatri adds. The vapors emitted when someone smokes e-cigarettes contain volatile organic compounds, heavy metals and other chemicals linked to lung disease.
“Being smoke-free, including in the home, is your best approach,” she says.
Household cleaners
Household cleaning supplies are another common cause of indoor pollution. Harsh chemicals that give off fumes can irritate your nose, mouth and lungs, as well as your skin.
“Those with sensitive lungs and upper airways, like people with asthma and chronic sinusitis, may notice their symptoms getting worse,” Dr. Khatri says.
The fumes can cause inflammation that can make it more difficult for people with chronic lung conditions to heal from infections. It can also worsen inflammation due to other triggers, such as allergies.
Dr. Khatri recommends using natural cleaning supplies and elbow grease to minimize risks.
Other indoor pollutants that exacerbate asthma or other chronic lung conditions include:
Particulates from candles and incense.
Irritating perfumes.
Odors from harsh household cleaners.
Craft and office supplies, such as paints, glues and toner ink.
Fumes from dry cleaned garments (many solvents used are carcinogenic).
Allergens, such as mold, pollen, pet dander and dust mites.
Wood-burning fireplaces or stoves.
Improper ventilation in homes (can increase levels of radon and carbon monoxide gas).
Gas stoves that are not well ventilated with hoods to outside (can increase exposure to nitrogen dioxide, carbon monoxide and formaldehyde).
Materials used in older buildings such as asbestos, formaldehyde and lead.
