Ozone, Air Quality, and Asthma

If your child has asthma, you probably understand flare-ups. But there are steps you can take to minimize your child's exposure.

What Is Ozone?

Ozone is a gas that's found in both the Earth's upper and lower atmospheres. The protective ozone in the upper atmosphere is very different from the harmful ozone in the lower atmosphere. Ozone that exists naturally 10 to 30 miles (16 to 48 kilometers) above the Earth protects us all from the

Particle pollution refers to tiny particles of acids (such as nitrates and sulfates), dust, dirt, smoke, soot, and droplets from aerosols that are suspended in the air we breathe. The smaller the particles, the deeper they can get into the lungs, where they cause problems.

Twenty-three percent of the population of the United States, including 1,500,000 children with asthma, live in areas with levels of particle pollution that are unhealthy year-round.

In addition to ozone and particle pollution, other pollutants include gases such as carbon monoxide, sulfur dioxide, and nitrogen dioxide. High levels of these gases can also affect lung function.

How Poor Air Quality Affects People With Asthma

Air pollution is a problem for everyone - not just people with asthma. Studies have shown that high levels of air pollution can be associated with decreased lung function and more frequent reports of respiratory symptoms. This is especially true for people who spend a lot of time outdoors.

Children may be particularly affected by pollution levels because they:

  • play outdoors
  • have faster breathing rates
  • have lungs that are still developing

But although high levels of pollution affect everyone, people with asthma are more sensitive and experience the effects more quickly and severely. Additional studies have shown that ozone, particle pollution, and other forms of air pollution worsen asthma and increase hospital visits for people with asthma. And again, it's kids with asthma who are especially vulnerable to these effects.

Pollutants in the air have the same effect on people with asthma as other triggers. They reduce lung function by inflaming the lining of the lungs. Exposure to pollutants in the air can cause flare-ups and may increase the chance of upper respiratory infections, which can worsen asthma symptoms. If rescue medication on hand.

Improving the air quality in your home is also a good idea. You can do this by using an air cleaner, venting all gas appliances to the outside, and avoiding wood fires in your house.

You should also talk to your child's doctor about increasing medication during times when air pollution is high. This can be included as part of your child's

  • Don't drive - share a ride, take public transportation, ride a bike, or walk.
  • Don't put gas in your car until after 7 PM.
  • Avoid using outboard motors, off-road vehicles, or other gasoline-powered recreational vehicles.
  • Avoid mowing your lawn or using other gasoline-powered gardening equipment until the late evening or until the air quality improves.
  • Don't use paints, solvents, or varnishes that produce fumes.
  • If you're barbecuing, use an electric starter instead of charcoal lighter fluid.

    In addition to ozone and particle pollution, other pollutants include gases such as carbon monoxide, sulfur dioxide, and nitrogen dioxide. High levels of these gases can also affect lung function.

    How Poor Air Quality Affects People With Asthma

    Air pollution is a problem for everyone - not just people with asthma. Studies have shown that high levels of air pollution can be associated with decreased lung function and more frequent reports of respiratory symptoms. This is especially true for people who spend a lot of time outdoors.

    Children may be particularly affected by pollution levels because they:

    • play outdoors
    • have faster breathing rates
    • have lungs that are still developing

    But although high levels of pollution affect everyone, people with asthma are more sensitive and experience the effects more quickly and severely. Additional studies have shown that ozone, particle pollution, and other forms of air pollution worsen asthma and increase hospital visits for people with asthma. And again, it's kids with asthma who are especially vulnerable to these effects.

    Pollutants in the air have the same effect on people with asthma as other triggers. They reduce lung function by inflaming the lining of the lungs. Exposure to pollutants in the air can cause flare-ups and may increase the chance of upper respiratory infections, which can worsen asthma symptoms. If rescue medication on hand.

    Improving the air quality in your home is also a good idea. You can do this by using an air cleaner, venting all gas appliances to the outside, and avoiding wood fires in your house.

    You should also talk to your child's doctor about increasing medication during times when air pollution is high. This can be included as part of your child's

    Ozone, Air Quality, and Asthma

    If your child has asthma, you probably understand flare-ups. But there are steps you can take to minimize your child's exposure.

    What Is Ozone?

    Ozone is a gas that's found in both the Earth's upper and lower atmospheres. The protective ozone in the upper atmosphere is very different from the harmful ozone in the lower atmosphere. Ozone that exists naturally 10 to 30 miles (16 to 48 kilometers) above the Earth protects us all from the

    Particle pollution refers to tiny particles of acids (such as nitrates and sulfates), dust, dirt, smoke, soot, and droplets from aerosols that are suspended in the air we breathe. The smaller the particles, the deeper they can get into the lungs, where they cause problems.

    Twenty-three percent of the population of the United States, including 1,500,000 children with asthma, live in areas with levels of particle pollution that are unhealthy year-round.

    In addition to ozone and particle pollution, other pollutants include gases such as carbon monoxide, sulfur dioxide, and nitrogen dioxide. High levels of these gases can also affect lung function.
