Study: Clean air makes children's lungs stronger, healthier

Elena Craft

We’ve known for a long time that breathing polluted air can make you sick. Now there’s more evidence that breathing cleaner air can make you better.

The New England Journal of Medicine published new research this month detailing improved lung function in children that breathe cleaner air.

The Southern California study received major attention.

That’s not surprising – as it provides compelling evidence that efforts to improve air quality over the years have been successful in improving children’s health.

The study followed three populations of children, aged 11 to 15, for a period of four years. This age group was chosen because children’s lungs develop rapidly during this stage.

In all, the study examined more than 2,100 children in five distinct California communities.

The report found that the greatest improvements in lung function were seen with declining levels of particulate pollution, also known as soot; and of nitrogen dioxide, a fuel combustion byproduct.

And potentially the best benefit of all: Cleaner air doesn’t just lead to healthier lungs during childhood because the benefits last a lifetime. Children with healthier lungs grow up to be adults who have a lower risk of premature death and other serious health problems.

The bottom line?

We need and deserve policies to secure a wide range of protections for cleaner, healthier air. Fighting for stronger health protections against smog and defending the first-ever national standards to reduce mercury pollution and other air toxics from power plants are good places to start.

Please join us in giving future generations the best possible chance, today and tomorrow, for healthy lungs.

Thank you for helping spread the word about the negative effects of smog, especially on youth. While climate change steals the headlines, the fact that millions die due to air pollution related causes slips through the cracks.
