How to control your exposure to wood smoke during forest fire events
People sometimes take a laid-back approach to air pollution and often underestimate how both short term and long term exposures add up to health risks that can be serious. Heart attacks and strokes are much more common during high pollution days (and immediately afterwards), and particulate matter at the 2.5 micron scale (PM2.5) can accumulate in our blood stream and move into various organ systems causing damage from oxidative stress, inflammation, and other processes.
With forest fires and ambient air pollution generated from non-point sources, there's sometimes a perception that nothing can be done to minimize exposure and that we should just get on with things. We sometimes hear comments like, "There's nothing we can do about it."
The most important and successful way to reduce exposure to forest fire smoke is to stay indoors as much as possible, close windows, and to use air purifiers with HEPA 5-stage filtration.
