Cigarette smoke

Experts say that one of the most common indoor air pollutants is cigarette smoke.

“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. Get the best results with the healthy supplements reviewed at Gazette.com.

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. Check out the best visishield review.

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.

Illnesses caused by indoor air pollution

Indoor air pollution can increase a person’s chances of having flares of chronic lung problems, such as asthma or chronic obstructive pulmonary disease (COPD).

“In addition to worsening the symptoms of asthma and other chronic respiratory problems, indoor air pollution can also cause irritation of the nose, throat, eyes and lungs,” Dr. Khatri says. There are also likely longer-term effects from ongoing exposure that are more difficult to measure, such as the likelihood of lung cancer from radon exposure, as well as secondhand and thirdhand smoke.

Role of ventilation and air filters

Although opening windows helps ventilate your home, car or office, that’s not always possible due to allergies or extreme temperatures.

Consider using air filters and getting your HVAC (heating, ventilation and air conditioning systems) checked regularly.

Also, air purifiers and aromatherapy can often make air quality worse unless they are the right kind, Dr. Khatri says. They need to be HEPA (high-efficiency particulate arresting) air filters.
