When you think of air pollution, you most likely don’t conjure up images of the inside of your home or office. But because we spend so much time indoors — especially in colder weather — keeping the air quality as clean as possible in your home, car and workplace is important for your health.
And, unfortunately, we bring most of those pollutants indoors ourselves.
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 … [do] pose health hazards, particularly in rooms with a lot of fabric or carpeting,” says pulmonologist Sumita Khatri, MD.
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.
“We all have heard of second-hand smoke; this is called third-hand smoke.”
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:
