Even more risks now to our health and our planet from additional air pollutants.

Recently I experienced firsthand the effects of forest fires burning in Colorado.  I had never seen or felt anything quite like this. The smoky haze is almost palpable, skies are tinged with a drab color that is far removed from the blue we expect. Wildfires in California are especially bad now, in a year that was already marked by unprecedented events. David Salesin captured this shot in Sausalito the other morning around 10 am, looking out towards San Francisco. What is typically a vantage point of picture-postcard beauty is now sadly a reminder of not only the current terrible situation, but also that our planet is becoming more and more toxic every single day.
And the effects are not just impacting our pulmonary or cardiovascular health – we now know that our brain health is equally compromised.

Mounting evidence links a variety of neurological problems to dirty air that is particularly exacerbated in urban cities throughout the world. Recent findings have shown hallmarks signs of Alzheimer’s disease in the brains of children living in Mexico City.1 Older women in the U.S. who live in highly polluted areas have a nearly doubled risk of dementia.1 Rates of autism are also notably higher in more polluted geographic locales and studies have shown that prenatal exposure to air pollution increases the risk of developing the disorder.2

The global impact of air pollution was the focus of a paper in The Lancet Neurology3 that cited among other findings “that air pollution might cause 30% of all strokes, and thus might be one of the leading contributors of the global stroke burden” as was highlighted in an analysis of stroke and risk factors from the Global Burden of Disease Study 2013. The mechanism of action is most likely a direct effect of particulate matter—a mixture of solid particles and liquid droplets found in the air and in gases such as ozone and nitrogen dioxide—on the vascular system, causing oxidative stress and inflammation.

Even if the risks of neurological effects for individuals that is attributable to air pollutants might be small to modest, the overall attributable risk could be considerably higher, given that a large proportion of the population is exposed to air pollutants. Also noted by The Global Burden of Diseases, Injuries, and Risk Factors (GBD) Study reported that “air pollution alone was responsible for 6·7 million deaths globally in 2016.” The Study also cited that 92 percent of all deaths linked to air pollution were in lower to middle income countries – yet another example of the disproportionate burden faced by individuals with less access to regular or even any healthcare and related education about these issues.

A mix of released gases and fine particles from burning trees and plants, structures, and other materials, wildfire smoke is now estimated to bear 40 percent of the responsibility for particulate matter pollution. But it’s hardly the sole contributor to dirty air. Vehicle exhaust fumes, burning of fossil fuels, chemicals used in agriculture and other settings, construction with lack of proper land reclamation, industrial emissions and so many other factors put virtually all of us at some risk of breathing dirty air. Globally, more than 90 percent of people breathe air that fails to meet WHO standards* and that includes an estimated four in ten people in the United States alone whose health may suffer from the negative effects.

In addition to advocating for cleaner industrial and commercial manufacturing and other standards, there are a few things we can all do to try and help reduce air pollutants:
  • Always use clean air filters in your central heat and air conditioning system.
  • Remember to clean or replace other air filters too, e.g. air purifiers, vacuum filters.
  • A high quality air purifier is an excellent investment in breathing easier. Some of our favorites:  Austin Air https://austinair.com/  Molekule https://molekule.com/  IQ Air Filters https://www.iqair.com/
  • Commit to dust-free environments – vacuum or mop and dust surfaces regularly.
  • Got pets? Keep them brushed and bathed to reduce hair/fur and dander.
  • Consider indoor greenery, barring any allergies, which may help clean the air naturally.
  • But don’t forget to dust or wipe off those plant leaves when you’re cleaning.
  • Swap out some days of driving or using public transit with walking or riding a bike. And carpooling is also a great option.
  • Don’t burn trash, including toxic ink-laden paper waste, especially in wildfire-prone areas and during drought seasons.
  • Look for ENERGY Star products and “clean fuels” when filling up; and get even more ideas at EPA.gov, https://www3.epa.gov/region1/airquality/reducepollution.html

Experts warn that forests lost to wildfires may never fully regenerate at least in the near future and especially not at lower elevations. And without the ability to capture carbon through trees, climate change is only going to intensify. We are living in literally toxic times and it is a problem we must solve together. It’s about more than making a difference to our brain or overall health – it’s truly about the health of our planet today and tomorrow.

In hope and healing,
Dr. Suzanne Gazda
