Mitigating that Pesky Canadian Particulate Matter

Mitigating that Pesky Canadian Particulate Matter

You've Got Some Nerves

Last week saw much of the Pacific Northwest blanketed by smoke from wildfires in British Colombia. As I pondered the gray haze Thursday, I recalled a piece from a fellow columnist in June about air pollution and MS. In addition to MS, I also have asthma. Therefore, the health effects of air pollution are something I thought I understood. I kicked my HEPA air cleaner up a notch and sat down at the computer.

It turns out, air pollution has been linked with several neurodegenerative diseases. According to one group of researchers, evidence suggests that major mechanisms involved in MS pathogenesis, “… such as inflammatory factors expression, free radicals overproduction, the blood brain barrier (BBB) breakdown, neuroinflammation, vitamin D deficiency and mitochondrial dysfunction could also occur due to exposure to air pollutants.” They hypothesize that air pollution may initiate a cascade of events that leads to brain autoimmunity. In other words, perhaps exposure to air pollution can go into the box of puzzle pieces that I call “What Causes MS.”

The study cited by my colleague looks at the link between particulate air pollution that is 10 micrometers in diameter, otherwise known as PM10, and MS relapse or exacerbationThe authors did find a positive correlation between exacerbation and air pollution, likely through oxidative stress. In 2013, research from Tehran indicated that air pollution “might be regarded as a factor for MS relapse.” The findings were not as strong as the study from France. They also looked at multiple air pollutants, not just particulate matter.

The most common cause of air pollution where I live is PM2.5, caused by wood smoke and diesel exhaust. These ultrafine particles are particularly problematic because they travel deeply into the lungs, carrying other pollutants as hitchhikers. In fact, they are so small they can move into the bloodstream and cause cardiovascular problems such as heart attacks or strokes. The vision of these pieces of Canadian forest entering my bloodstream gave me pause. What about the blood brain barrier (BBB)? In MS, the blood brain barrier is somehow broken down and immune cells cross over and attack myelin. Are the little Canadian lumberjack particulates hacking away at my BBB?!

Not all studies that looked at MS and air pollution found a connection. It seems this is an area for further research. But another study out of Tehran looked at the link between air pollution and Vitamin D levels in healthy women. There was a positive correlation between high levels of air pollutants and low levels of Vitamin D. Given what we know about MS and Vitamin D, it seems possible that air pollution could be a double-edged sword for those of us with MS.

What can we do to defend ourselves against air pollution?

Although we cannot change the wind direction or extinguish wildfires, there are a few things within our control:

  • Sign up for air-quality alerts from your regional air-monitoring agency and follow its guidelines.
  • Invest in a HEPA air cleaner and avoid electrostatic or ionizing devices.
  • Avoid additional sources of air pollution. Use the recycle feature on your car air intake, if you’re stuck in traffic. Avoid secondhand smoke or chemical odors, and don’t use aerosol products. (Speaking of secondhand smoke, if you’re a smoker, consider quitting. Smoking is linked to worsening MS).
  • Try not to sit downwind of campfires, barbecues, etc.
  • Get your vitamin D levels checked and take your supplements.
  • Eat foods high in antioxidants to counter the effects of oxidative stress.

If you’re so inclined, advocate for cleaner air in your community. That may mean no diesel buses, limits on wood burning or tighter controls on industry.

For the moment, I’m going to take an extra Vitamin D, check tomorrow’s air forecast and go to bed … hoping that visions of little lumberjacks don’t dance in my head!

    Thankyou for sharing. My fiance was diagnosed acouple years ago. She lost all but about 10% vision in her left eye. The treatments are working but the wildfire smoke is creating breathing issues. MS should stand for mystery symptoms….

      I have neurological symptoms have had for a long time. In the past 3 years I have been diagnosed with a MCS Multiple Chemical Sensitivity a Functional Movement disorder and likely a few other things I can’t recall and don’t think matters to this post. There are a host of issues with MCS and chemicals sufferers react to are as varied as the type of symptoms they have. I for one would not be surprised to learn MCS if a precurser for MS. I was reading about MCS today trying to get an edge to keep my symptoms down as usual and I found this https://www.sciencedirect.com/science/article/pii/S0048969717322519
      Emergency multiple sclerosis hospital admissions attributable to chemical and acoustic pollution: Madrid (Spain), 2001–2009

      I will save you the energy of reading tho I bet you read it anyway I would … at the end of it all the study concluded the traffic noise cause the increase emergency visits… not chemical reactions to pollution. Yep noise. I think maybe they don’t know what they should be looking at in the air seems to be common sense to me.

      When my movement problems first surfaces in 2005-6 the first thing to be checked for by my specialist was MS… head drops foot dragging a few other things were in play at the time. The MRI on my brain was non specific there were things there but not exactly what one would find in MS so I was left with no real diagnosis. Tried on a few drugs taken off a few other drugs. Had some withdrawal reactions that took years to clear long story short. Fast forward to a few years ago he jerking took on the look of ALS and I could not longer control my body. Oddly enough the first glimmer of hope for this round was antibiotics I took for something else it stopped the jerking dead… but it keeps coming back. I have been on several antibiotics in the past few years to treat cycling infections and my ALS like symptoms have improved… I am not out of the woods if I am around chemicals the ALS like symptoms pop back in almost immediately. There are many other things that warn me ahead of time to get away from the chemical some I can’t smell like perfume… but I react without smelling them… I get dizzy confused blurry vision ect… time to run if I can put on a chemical reducing mask and make my getaway. Now I could be a rare duck that nobody will ever be able to help I may have a psychiatric disorder https://www.sciencedirect.com/science/article/pii/S0733861910001386
      I just doubt it and my body tells me chemical avoidance improves my health. It may well be chemical avoidance may help people suffering from MS and that there is some as of yet connection between MCS and MS I can’t say as I don’t really know. This is what I do know avoiding chemicals is not as simple as it sounds it is complex requires constant work to weed out and avoid chemicals as much as possible including things we put on and in our bodies. Many websites are full of the dos and don’ts. Wearing a serious mask like a half face respirator is one thing MCS people find helpful avoiding not only all fragrance no matter the source and a huge list of chemicals in personal care products cleaning products and food… yes it is complex and hard work to maintain but worth the effort if it does indeed lower symptoms for MS as it does for MCS.
      What I know is I have improved by avoiding chemicals. If your interested in learning about MCS I will give you the link where I found the MS pollution page it was in a list of MCS links here

      I hope it helps somebody.
