Since 2020, there have been more than 183,000 wildfires on U.S. soil. In total, they’ve burned more than 20 million acres of federal, private and tribal land. That’s bad news for our planet — and also its inhabitants.
Wildfires displace both humans and animals, consuming entire neighborhoods and clearing diverse ecosystems. According to new research, they could also cause a surge in skin disease. The first-of-its-kind joint study conducted by researchers at UC San Francisco and UC Berkeley determined that wildfire smoke, like car exhaust and industry offput, can penetrate the skin, our body’s foremost defense system. Even worse, this isn’t just the case for those with eczema or rosacea. In fact, 89 percent of patients studied had no skin issues whatsoever.
While smoke and the toxins hidden within it are the most concentrated in evacuation zones, the exposure areas can stretch considerably further. As wildfires become more common due to climate change, reports of smoke reaching the other side of the country are no longer rare. Thousands of miles from the red-hot flames, smoke descends on cities as far east as New York and Philadelphia, which are located in states with historically low wildfire risk.
To reduce exposure, people should limit outdoor activity when the AQI (Air Quality Index) is higher than 100. Anti-pollution skincare products — an emerging category that includes creams, mists and more — may also help protect those exposed to unhealthy air by strengthening your body’s first line of defense against airborne pollutants.
