Some of the sources include: gases from oil, gas, or even wood for heating and cooking; cigarette smoking; building materials, such as asbestos insulation and products made from pressed wood; outdoor pollution that come indoors such as radon; cleaning supplies’ chemicals; hair spray and nail polish remover; molds and mildew and pet dander. Any time that your home lacks air circulation, pollutants increase inside your home.

Run a dehumidifier in the humid summer months, particularly your basement can help eliminating some potential sources. Set your dehumidifier between 30-50, and be sure to place one in the basement. Another important factor to help indoor air quality is to open windows once in awhile to let fresh air in.

Standing water, water-damaged materials, or wet surfaces also serve as a breeding ground for molds, mildews, bacteria, and insects. House dust mites, the source of one of the most powerful biological allergens, grow in damp, warm environments.

Like the way you would to avoid exposure to other air pollution, you should stay indoors to protect yourself from particle pollution. When the air is hazy, avoid going out or staying outdoors for long period of time if you have asthma or other related problems. Avoid bringing young children out. Stay indoors and plan fun activities at home. The advantage of living in smaller cities and rural areas is that you can enjoy outdoors more often. But the irony is that big cities dwellers tend to go out much more often than rural residents.

People with chronic lung conditions such as asthma, emphysema, and bronchitis may be more sensitive to the effects of ozone. Ozone can also have a greater impact on the health of children and adults who are physically active outdoors when ozone levels are high. So limit your activities outdoors during those periods, especially for asthma patients, young children and pregnant women.

While Ozone layer protects us from getting all the UV rays, ground-level ozone is a pollutant that can harm the environment, crops, and human health. It is ozone in the lower atmosphere, close to the Earth’s surface. This is one of the main components of smog. Ground-level ozone is formed when sunlight and heat cause chemical reactions between nitrogen oxides and volatile organic compounds .

Volatile organic compounds are pollutants released by motor vehicles, factories and power plants, and chemicals such as paints and cleaners. Since we live in a modern world and we are exposed to all these wherever we go.

In extreme cases, exposure to air pollutants at high levels over a long period of time may lead to cancer, birth defects, brain and nerve damage. It can cause long-term injury to the lungs and breathing passages.

Air pollution doesn’t just affect women, children, and elderly, it affects everyone. Children are especially susceptible to the effects of air pollution because their lungs are developing. Outdoor air pollution also adds more harms to people who have lung and heart diseases because they are more sensitive.

In the U.S., ground-level ozone and particle pollution are two of the most common pollutants and threat to people’s health.

When the levels of air pollution are high, you can protect yourself and your family by limiting outdoor physical activity. This is because physical activity can cause you to take faster, deeper breaths, inhaling more pollutants into your lungs.

Air pollution affects everyone. Children are especially susceptible to the effects of air pollution because their lungs are developing. They also spend more time active outdoors. People with lung and heart diseases are also more sensitive to outdoor air pollution.

The U.S. Environmental Protection Agency (EPA) sets limits on certain air pollutants throughout the United States. Ground-level ozone and particle pollution are two of the most common pollutants and pose the greatest threat to human health in the United States.

Remove indoor plants if they irritate or produce symptoms for you or your family.
