When certain air pollutants from particles and gases contaminate indoor air, it can escalate into indoor air pollution. The following are the most significant causes of indoor air pollution..
Asbestos is found in various materials used in home construction such as coatings, paints, building materials, and ceiling and floor tiles. Since 1989 asbestos has been partially banned partially in the U.S., so it’s much less of a threat in houses built since then. However, in homes built before 1989, the risk of asbestos is substantial.
2. Formaldehyde/Pressed wood products
Formaldehyde is an important chemical used widely by industry to manufacture building materials and numerous household products such as paints, sealants, and pressed wood products. In 2018, it became illegal to manufacture or import composite wood products in the United States if they contain excessive amounts of formaldehyde. Formaldehyde is also a by-product of combustion, such as cigarette smoke and cooking. Formaldehyde tends to be omnipresent, indoors and outdoors, at low levels. In higher concentrations and sustained exposure, formaldehyde can cause irritation of the skin, eyes, nose, and throat as well as cause some types of cancers.
Did you know?
For many people, air pollution is an outside thing—think exhaust spewing from cars or factory chimneys belching smoke—not something that happens inside our ordered, cozy homes. But according to the Environmental Protection Agency (EPA), the surprising truth is the air inside our homes might be up to five times more polluted than the air outside.
Combine that with research that suggests people spend roughly 90 percent of their time indoors and you have a perfect storm of why air pollution can lead to significant health conditions. In 2014, a World Health Organization (WHO) report stated air pollution had become the world’s single biggest environmental health risk, linked to around 7 million deaths in 2012.
Indoor air pollution
The issue is even more insidious because you can’t see air pollution with the naked eye—a lack of smog is no indication of purity. And despite all our attempts to keep our indoor spaces tidy, ultimately it takes more than cleanliness to improve indoor air quality.
In the last decade, a growing body of research confirms that even in the largest and most industrialized cities, the pollution in the home can far exceed what’s outside it.

Nearly everyone has experienced an occasional sleepless night. But when does the inability to sleep turn into insomnia? To answer that question, we need to look at how insomnia is defined medically.
In many research papers, insomnia is described as a disorder with one or more of the following criteria:
Having any of these sleep issues can lead to a diagnosis of insomnia. There are two basic types of insomnia: acute (short-term/several weeks) or chronic (ongoing/several months).
