The Children’s Mental Health-Air Pollution Clue We Can’t Ignore

When we think about children’s mental health triggers, we tend to blame the strains of social media, overscheduling, and trauma.

And to be clear, those are all contributing factors.

But a new study suggests what’s in the air could have acute impacts, too. And depending on the neighborhood you live in, the air children’s mental health-air pollution threat could be genuine.

The latest alarm bells stem from a 2019 study published in Environmental Health Perspectives.

Researchers at the Cincinnati Children’s Hospital Medical Center and the University of Cincinnati found an association between short-term exposure to ambient air pollution and a spike in psychiatric disorders in children.

Although the pollution levels fell within an acceptable range according to the EPA’s National Ambient Air Quality Standards,

they still seemed to induce “psychiatric exacerbations” in children who were taken to the emergency department with symptoms of conditions like depression, schizophrenia, and suicidality.

Major Takeaways of the Children’s Mental Health-Air Pollution Study

For this five-year study conducted in Cincinnati, researchers analyzed the connection between ambient air pollution and mental health disorders in children.

But let’s back up for one second. What is ambient air pollution, exactly?

This is when atmospheric air contains potentially harmful pollutants emitted by industry, households, cars, and trucks, according to the World Health Organization.

The WHO warns that delicate particulate matter in air pollution poses the most significant effects on human health.

Most fine particulate matter comes from fuel combustion emitted from vehicles, power plants, households, and more.

For the study, monitored and evaluated exposures to ambient particulate matter with an aerodynamic diameter of 2.5 microns or less.

Here are the major takeaways from the study:

  • Researchers measured pediatric emergency room visits in Hamilton County, Ohio, for five years. During this period, 13,176 pediatric psychiatric visits occurred.
  • The most frequent categories of psychiatric conditions included depressive disorders, externalizing disorders, impulse control disorders, personality disorder, PTSD symptoms, schizophrenia, and suicidality.
  • Data indicate significant associations between an increase in ambient particulate matter and any psychiatric visit.
  • When grouped by psychiatric encounter type, data shows that increased air pollution was significantly associated with emergency department visits related to schizophrenia on the same day of exposure, adjustment disorder and suicidality one day after exposure, and other mood disorders two days after exposure.
  • Children living in disadvantaged neighborhoods proved to be more susceptible to the detrimental effects of air pollution, especially for mental health disorders related to anxiety and suicidal thoughts/plans. This suggests that pollution exposure and neighborhood stressors may have synergistic effects on mental health disorders.

Where Is It Coming From?

One of the scariest facts about this recent children’s mental health-air pollution study is that all daily exposures to air pollution registered below the National Ambient Air Quality Standards set by the U.S. Environmental Protection Agency.

The study measured what’s called “fine particulate matter” in the air.

This type of air pollution is known to have the most significant effect on human health. It’s composed of inhalable particles made up of sulfate, ammonia, nitrates, black carbon, sodium chloride, mineral dust, and water.

The smaller the particles get — like when they’re less than 2.5 microns, the higher the health risk after exposure. This is because smaller particles are more able to penetrate our lungs and enter the bloodstream.

According to the World Health Organization, the primary sources of outdoor air pollution include the following:

  • fuel combustion from cars, trucks and heavy-duty vehicles
  • industrial activities, such as building, mining, and smelting
  • heat and power generation from power plants (both oil and coal) and boilers
  • industrial facilities, including manufacturing factories, oil refineries, and mines
  • waste sites, both municipal and agricultural
  • use of pollutant fuels for heating homes and cooking

Particulate matter is also present in indoor air pollution, from cooking, mold, household products, furnishings, and paint.

Exposure to these types of air pollution are dangerous for all humans but can be particularly harmful to children and adolescents.

Children are more likely to be exposed to air pollution because they generally spend more time outdoors, engaging in physical activity. And compared to adults, they breathe more air per pound of body weight.

What to Do About It

The EPA offers a few recommendations for people experiencing exposure to high levels of fine particle pollution.

  1. People are advised to stay indoors in an area with filtered air and to keep activity levels low.
  2. Using a HEPA air filtration to clean indoor air is proven to reduce delicate particulate matter. If you don’t have a HEPA air filter at home, spend time in public spaces with filtered air, like a library or mall.
  3. Pay attention to the Air Quality Index in your area (using AirNow.gov) so that you’ll know when to protect yourself from hazardous levels of ambient air pollution.

It’s also important to take steps to purify the air in your home, where children spend most of their time.

You can do this by choosing environmentally friendly cleaning and beauty products, like the ones suggested by the Environmental Working Group.

Choosing organic and natural home furnishings will also help to reduce your exposure to pollutants. And adding houseplants that remove pollution to your home, like spider plants, jade plants, and bromeliad, has shown to reduce pollutants.

And finally, we need to shift toward cleaner energy and updated chemical regulations if we’re going to create good work for our children.

Final Thoughts

  • A recent study conducted in Cincinnati, Ohio, suggests that short-term exposure to air pollution from particulate matter is associated with psychiatric emergency department visits in children and adolescents.
  • Air pollution caused by fuel combustion, industrial activities, power generation, and waste sites is contributing to a significant air quality epidemic.
  • Until our nation and world begin to implement useful guidelines for reducing air pollution, you can minimize your family’s exposure by using an air filter at home, choosing environmentally friendly household products and furnishings, and using houseplants that have proven to reduce pollutants. But ultimately, we can’t solve this problem without widespread changes on the national and global scales.
