Indoor Air and Health Problems
Indoor air quality (IAQ) refers to the quality of the air inside buildings and structures, including homes, schools, and workplaces. Many people spend most of their time indoors, which means that indoor air quality can have a significant impact on their health. Poor indoor air quality can cause a variety of health problems, including respiratory issues, lung cancer, and other health concerns. In this article, we’ll explore the effects of indoor air pollution on health, common indoor air pollutants, and ways to improve indoor air quality.
What is Indoor Air Pollution?
Indoor air pollution refers to the presence of pollutants in the air inside buildings, such as homes, offices, and schools. These pollutants can come from a variety of sources, including building materials, cleaning products, and outdoor pollution that enters the building.
Indoor air pollution can have a significant impact on our health, as we spend most of our time indoors. Exposure to indoor air pollution can cause a range of health effects, including respiratory issues, allergies, and even cancer.
Some of the most common sources of indoor air pollution include:
- Building materials: Building materials, such as carpets, furniture, and insulation, can release volatile organic compounds (VOCs) into the air. These chemicals can cause eye and respiratory irritation, and some VOCs are known to be carcinogenic.
- Cleaning products: Many commercial cleaning products contain harsh chemicals that can release VOCs and other pollutants into the air. These chemicals can cause eye and respiratory irritation and can aggravate existing health conditions.
- Outdoor pollution: Outdoor pollution, such as particulate matter and ozone, can enter buildings through ventilation systems and open windows and doors. Exposure to outdoor pollution can cause respiratory issues and other health problems.
- Cooking and heating: Cooking and heating appliances, such as gas stoves and furnaces, can release pollutants, such as carbon monoxide and nitrogen dioxide, into the air. Exposure to these pollutants can cause respiratory issues and other health problems.
- Smoking: Smoking inside buildings can release a range of pollutants into the air, including carbon monoxide, particulate matter, and VOCs. Exposure to secondhand smoke can cause respiratory issues and increase the risk of cancer.
Reducing indoor air pollution requires identifying potential sources of pollution and taking steps to address them. By improving indoor air quality, we can help protect our health and the health of those around us.
Common indoor air pollutants include:
- Biological pollutants: These include mold, bacteria, viruses, and other microorganisms that can cause respiratory issues and other health problems.
- Particulate matter: This includes tiny particles that are suspended in the air, such as dust, pollen, and smoke. These particles can cause respiratory issues and aggravate existing health conditions.
- Volatile organic compounds (VOCs): These are chemicals that are emitted by many building materials, cleaning products, and furniture. They can cause eye and respiratory irritation, and some VOCs are known to be carcinogenic.
- Carbon monoxide: This is a poisonous gas that is produced by combustion, such as from gas stoves, fireplaces, and furnaces. Exposure to high levels of carbon monoxide can be fatal.
- Radon: This is a naturally occurring gas that can seep into homes and other buildings from the ground. It is the leading cause of lung cancer in non-smokers in the United States.
- Formaldehyde: This is a VOC that is commonly found in building materials, such as plywood and particleboard. It can cause eye and respiratory irritation and is a known carcinogen.
- Asbestos: This is a fibrous mineral that was commonly used in building materials until the 1970s. Exposure to asbestos can cause lung cancer and other respiratory issues.
- Lead: This is a toxic metal that was commonly used in paint until it was banned in the United States in 1978. Lead exposure can cause developmental and neurological problems in children.
- Ozone: This is a gas that is created by chemical reactions between pollutants and sunlight. It can cause respiratory issues, particularly in people with asthma.
- Nitrogen dioxide: This is a gas that is produced by combustion, such as from gas stoves and cars. It can cause respiratory issues and aggravate existing health conditions.
The Effects of Indoor Air Pollution on Health
Poor indoor air quality can have a significant impact on your health. Here are some of the health effects associated with indoor air pollution:
Respiratory Issues: Exposure to indoor air pollutants can cause respiratory issues such as coughing, wheezing, and shortness of breath. People with asthma are particularly vulnerable to the effects of indoor air pollution, which can trigger asthma attacks.
Lung Cancer: Exposure to radon, a common indoor air pollutant, is the leading cause of lung cancer in non-smokers in the United States.
Other Health Concerns: Poor indoor air quality has also been linked to a variety of other health concerns, including headaches, fatigue, and irritation of the eyes, nose, and throat.
Improving Indoor Air Quality
Improving indoor air quality is essential for protecting your health and the health of those around you. Here are some ways to improve indoor air quality:
- Increase ventilation: One of the simplest ways to improve indoor air quality is to increase ventilation. Open windows and doors to let in fresh air or use a mechanical ventilation system to circulate air throughout your home.
- Control humidity: High humidity levels can promote the growth of mold and other microorganisms, which can reduce indoor air quality. Use a dehumidifier to keep indoor humidity levels between 30 and 50 percent.
- Regular cleaning: Regular cleaning can help reduce indoor air pollutants, such as dust, dirt, and pet dander. Vacuum carpets and upholstery regularly, and dust surfaces with a damp cloth to reduce the amount of dust in the air.
- Use low-emitting building materials: When building or renovating your home, choose building materials that emit low levels of VOCs, such as low-VOC paints and adhesives.
- Maintain your HVAC system: Regularly maintain your heating, ventilation, and air conditioning (HVAC) system to ensure that it is operating efficiently and circulating clean air throughout your home.
- Test for radon: Radon is a naturally occurring gas that can seep into homes from the ground. Test your home for radon levels and take steps to mitigate high levels.
- Use natural cleaning products: Many commercial cleaning products contain harsh chemicals that can release VOCs into the air. Use natural cleaning products, such as vinegar and baking soda, to clean your home.
- Keep indoor plants: Indoor plants can help improve indoor air quality by absorbing carbon dioxide and other pollutants from the air.
- Address mold and water damage: If you notice mold or water damage in your home, address it immediately. Mold and water damage can promote the growth of mold and other microorganisms, which can reduce indoor air quality.

The Role of the Environmental Protection Agency (EPA)
The Environmental Protection Agency (EPA) is responsible for regulating indoor air quality in the United States. The EPA sets standards for indoor air pollutants and provides information on how to improve indoor air quality. The EPA also offers resources for homeowners, schools, and businesses on how to identify and address indoor air quality issues.
In addition, the EPA has developed the Indoor air PLUS program, which is designed to help builders and developers construct homes with better indoor air quality. Homes that meet the Indoor air PLUS guidelines have features such as enhanced ventilation systems, low-VOC building materials, and radon-resistant construction.
Conclusion
In conclusion, poor indoor air quality can have a significant impact on your health. Indoor air pollution can cause respiratory issues, lung cancer, and other health concerns. Common indoor air pollutants include radon, carbon monoxide, allergens, VOCs, and particulate matter. Fortunately, there are many ways to improve indoor air quality, such as ventilation, humidity control, and regular cleaning. The EPA plays an important role in regulating indoor air quality and providing resources for improving indoor air quality. By taking steps to improve indoor air quality, you can help protect your health and the health of those around you.
