Smoke from wildfires in Canada and Minnesota prompted more air quality alerts Friday in the Northeast and Mid-Atlantic U.S., as well as in the Upper Midwest.<\/p>

Michigan saw a statewide air quality advisory on Wednesday, and Minnesota’s air quality reached the hazardous “purple” alert level. The wildfire smoke is setting records in Wisconsin and turning skies orange in Vermont. And after a brief respite Friday morning, New York City will see more smoke.<\/p>\n

Climate <\/h3>\n

Farmworkers feed the country, but who protects them from wildfire smoke?<\/h3>\n<\/div>\n\n<\/div>\n\n<\/div>\n\n

Exposure to wildfire smoke is a growing health problem across the country, as human-caused climate change increases the risk and intensity of wildfires and the smoke that can drift thousands of miles downwind from them.<\/p>

Here’s what you need to know about the health risks \u2014 and how to protect yourself.<\/p>

May-Lin Wilgus, a pulmonologist and professor at UCLA, compares breathing wildfire smoke to smoking cigarettes \u2014 a lot of cigarettes.<\/p>

Scientists track air quality with the air quality index, or AQI, which incorporates different pollution sources like ozone and fine particulates. Many scientists don’t think there’s a “safe” AQI level because the measurement doesn’t capture many harmful pollutants, but under 50 is often considered acceptable. Higher numbers indicate more health-damaging pollution in the air.<\/p>

On Friday morning, the AQI in Detroit was 435 \u2014 the worst for any major city in the world. On a smoky day, when AQI levels reach 100 to 200, “the exposure to the fine particulate matter, the air pollution, is similar to smoking a quarter to half a pack a day,” Wilgus says.<\/p>

That exposure takes a toll on a healthy person. But it is particularly harmful for those with preexisting health issues, Wilgus adds. Emergency room visits for respiratory issues like asthma and COPD increase dramatically during wildfire smoke events, as much as doubling in some cases. During the Canadian wildfires in 2023, when smoke wafted across much of the U.S., emergency room visits for asthma increased by nearly 20%.<\/p>\n\n

Smoke exposure can also worsen other medical conditions. Emergency departments see more cardiovascular related visits after smoky days. And a growing body of research suggests smoke exposure is linked to long-term impacts such as a higher risk of developing dementia.<\/p>

Overall, air quality has improved in the U.S. over the past 20 years, says Tarik Benmarhnia, a climate and health scientist at the Scripps Institution of Oceanography at the University of California, San Diego. But wildfire smoke is erasing many of those gains.<\/p>

“Just maybe like 10 years ago, wildfire was an exceptional issue. It was something that happens once in a lifetime for most people,” he says.<\/p>

But climate change has increased the chance of wildfires across many parts of the country and the intensity of many of the burns themselves and the smoke they produce.<\/p>

“This is unfortunately not the first one and not the last one the people in Los Angeles are going to be experiencing,” Benmarhnia says.<\/p>

Wondering what AQI is safe and what activities are safe at different AQIs? Life Kit explains.<\/p>

Wildfires burn at extremely high temperatures, which makes their ash more toxic than other pollution, such as car exhaust. But in many cases, including during these ongoing fires,it’s not just trees and organic matter that burn. Homes, cars and other materials go up in flames, too, adding potentially harmful particles to the pollution load.<\/p>

“It’s just a toxic soup,” says Lisa Miller, a wildfire smoke expert at the University of California, Davis. “Think of all the synthetic fibers that are present in your living room \u2014 in your couch, in your carpet, in your clothes. All those things can be particularly toxic” if they go up in smoke, she says.<\/p>

Wildfire smoke is hazardous for everyone, but it’s especially dangerous for some people, including children and older adults, pregnant people and anyone with preexisting health problems.<\/p>\n

First responders and firefighters are exposed to the worst of the smoke. A 2019 study found that heavy, repeated smoke exposure among wildland firefighters is linked with .<\/p>

Children can be especially vulnerable, doctors say, because they breathe in more air \u2014 and therefore more smoke \u2014 relative to their body size.<\/p>

Pregnant people should also take care, says Miller. There’s growing evidence that wildfire smoke exposure is linked with higher chances of preterm birth and lower birth weights, an outcome sometimes linked with health issues later in life.<\/p>

Older people and those with preexisting health problems like heart issues are also at higher risk.<\/p>

The Shots Blog breaks down advice for how to protect people who are more at risk from wildfire smoke.<\/p>

“If you can smell smoke, those are times to limit your exposure as much as possible,” says Wilgus. She says the best way to protect yourself is to leave the area and get outside the range of the wildfire smoke, if possible.<\/p>

How to protect yourself from poor air quality <\/h3>\n<\/div>\n\n<\/div>\n\n<\/div>\n\n

If that’s not an option, she suggests staying indoors with the windows tightly shut. Limit your physical activity. Run an air filter if you have one.<\/p>

If you have to go outside, consider wearing an N95 mask, which effectively blocks most tiny particles from getting into your lungs if worn correctly.<\/p>

No level of exposure to wildfire smoke is completely safe, says Miller. But toxicologists have a saying, she says: “The dose makes the poison. It’s about how much, and how long, you’re exposed.”<\/p>
