The holiday season gives us plenty of reasons to brave the cold and head outside, whether it’s walking through downtown to see the decorations or playing in the snow when it finally falls. It’s hard to imagine a winter without being able to enjoy these activities. But for people with lung disease, soot pollution in the air may keep them from taking part in the traditions we all love.
Soot, also called particle pollution, can fill our air and threaten our health all year round. These particles come mainly from vehicles and coal-fired power plants and other industrial sources, and they’re so small that once they’re inhaled, they can become lodged deep in the lungs.
