“Air pollution is the world’s fourth leading cause of disease and death — and most of these deaths are due to cardiovascular disease, not lung conditions or cancer,” warns Dr. Jamal S. Rana, a cardiologist with The Permanente Medical Group, as quoted in a recent Kaiser Permanente study. That’s a wake-up call for the 320,000 Southern Californians now under an air quality alert thanks to smoke from the Wolf and Mindy fires. With the Wolf fire still at 0% containment and stretching across 1,400 acres, and the Mindy fire at 70% contained after burning 100 acres, the situation is anything but routine.
The South Coast Air Quality Management District (AQMD) isn’t mincing words: “Particles in wildfire smoke can get deep into the lungs and cause serious health problems such as heart attacks, strokes, asthma attacks, and difficulty breathing.” And it’s not just a theoretical risk. During the Mendocino Complex fires, researchers found a 23.1% increased rate of heart attacks, heart failure, stroke, and cardiovascular deaths on days with high smoke levels, compared to days with good air quality 23.1% increased rate of heart attacks, heart failure, stroke, and cardiovascular deaths.
So, what does this mean for families in Idyllwild, Palm Springs, Coachella, and beyond? For starters, everyone is at risk—but certain groups need to be extra cautious. According to a major study out of UC Berkeley, children, older adults, people with heart or lung conditions, pregnant individuals, and those who spend lots of time outdoors are especially vulnerable to wildfire smoke’s effects children, older adults, people with heart or lung conditions, pregnant individuals, and those who spend lots of time outdoors are especially vulnerable. On heavy smoke days, hospital visits for asthma jump by more than 10%, with the highest spike among kids under five.
If you’re wondering what you can do right now, the answer is refreshingly practical. AQMD recommends staying indoors with windows and doors closed, running your air conditioner or a portable air purifier, and—if you must go outside—wearing a properly fitted N95 mask. “One of the most effective measures is the use of portable air cleaners, which have been shown to reduce indoor particulate matter by as much as 50-60%,” says Dr. Keith Churchwell, president of the American Heart Association use of portable air cleaners, which have been shown to reduce indoor particulate matter by as much as 50-60%. That’s a small investment for a big impact on your family’s health.
But there’s more to the story than just this week’s smoke. Climate change is turning up the heat—literally. California’s wildfire season is starting earlier, ending later, and burning bigger, thanks to hotter, drier conditions and earlier snowmelt California’s wildfire season is starting earlier, ending later, and burning bigger. In fact, nearly all of the increase in burned areas over the past half-century is due to human-caused climate change, with a +320% increase in burned areas from 1996 to 2021 +320% increase in burned areas from 1996 to 2021.
That means “bad air days” aren’t going away. So, what’s the best way to keep your indoor air as fresh as possible when the outside world looks like a sepia-toned movie set? The Environmental Protection Agency recommends upgrading to high-efficiency (HEPA) filters in your HVAC system and using portable air purifiers in bedrooms and living spaces. Avoid swamp coolers and whole-house fans during smoke events—they can actually pull more smoke indoors. And skip burning candles, grilling, or using gas-powered equipment until the air clears.
For families with pets, don’t forget: if it’s not safe for you, it’s not safe for them. Bring furry friends indoors and make sure they have access to clean water and cool spaces.
As the Wolf fire continues to burn with zero containment and evacuation orders still in place, officials are urging everyone to stay alert for updates. The AQMD will extend the air quality advisory if needed, and with extreme heat warnings also in effect, it’s a double whammy for heart and lung health.
Wildfire smoke isn’t just a nuisance—it’s a real health threat. But with the right tools and a little know-how, Southern Californians can protect themselves and their loved ones, even as the skies stay smoky.
