Asthma in kids and teens: healthy lungs need healthy air

By Lisa Richter, Neighborcare Health

According to the Asthma and Allergy Foundation of America (AAFA), more than 6.2 million children in the United States have asthma. It is the top reason why children miss school.

Asthma is a disease that affects the lungs and makes it hard for a person to breathe (learn more about asthma).  No one knows for sure what causes asthma, but there are key factors that increase the risk.  

  • Asthma tends to run in families. Children with parents who have asthma are more likely to have it too.
  • Allergies. People with certain allergies are more likely to also have asthma symptoms.
  • A lung infection at a young age. Lung infections in babies or young children can cause permanent damage to their lungs.
  • Air quality. Children who breathe polluted air outside or in the home are more likely to have asthma.

How does air quality cause asthma or trigger symptoms?

Air pollution is anything that can have a harmful effect on the air we breathe, such as dust, chemicals and gases. Some air pollution is man-made, such as car exhaust, and some happens naturally, such as dust or wildfire smoke. Cities are likely to have more air pollution because there are more people, vehicles and buildings. During childhood, the lungs are still growing and breathing polluted air can cause long-term problems. For people who already have asthma, air pollution can trigger symptoms and cause asthma attacks. 

For the last few years, smoke from wildfires has caused poor air quality during the summer here in Seattle. Unfortunately, more wildfires are expected this season. The Puget Sound Clean Air Agency website reports the air quality for King, Pierce, Snohomish and Kitsap counties. When there is smoke in the air, people with asthma should limit their time outdoors and stay in buildings with air conditioning, if possible. More tips. 

Air quality at home

Asthma in children has also been linked to exposure to tobacco smoke at home. Tobacco smoke can prevent children’s lungs from growing healthy.

According to the AAFA, children who breathe secondhand smoke (smoke that is exhaled or comes from a burning cigarette) miss school more often because they are sick or in the hospital. Children with asthma who are around secondhand smoke have more asthma attacks than children with asthma who are not around secondhand smoke.

Other things in the air at home, such as pollen, mold, pet dander or waste from common household pests, can also cause asthma or trigger symptoms. If you live in a household with a child who has asthma, use this free checklist to help you and your family improve the air quality in your home.

Getting treatment

Childhood asthma cannot be cured and can continue as children become adults. Getting treatment early can help control symptoms and prevent asthma attacks and damage to growing lungs. Make an appointment with your child's medical provider if you notice:

  • Coughing that is constant, off-and-on, or linked to physical activity
  • Wheezing or whistling sounds when your child breathes out
  • Shortness of breath or rapid breathing
  • Complaints of chest tightness
  • Your child has had bronchitis or pneumonia multiple times
