Wildfire smoke traveling from Canada has been reaching the Midwestern U.S., causing both outdoor and indoor air pollution, experts warn. In May, the smoke reached states such as Minnesota, Wisconsin, and Iowa, prompting counties to issue air quality alerts and advise residents to stay indoors. However, according to Joseph Allen, an associate professor at Harvard T.H. Chan School of Public Health, wildfire smoke can also seep indoors and lead to indoor pollution that poses health risks.
Allen emphasized that people spend most of their time indoors and can still be exposed to harmful smoke particles that can lead to cardiovascular issues and asthma exacerbations. Therefore, it is essential to address indoor air quality as a key component of climate resiliency in addition to focusing on outdoor air pollution.
Experts recommend implementing strategies to improve indoor air quality such as using portable air cleaners equipped with HEPA filters. By taking steps to filter indoor air, individuals can reduce their exposure to harmful pollutants and protect their health.
The goal is to create healthier indoor environments that minimize the impact of outdoor air pollution during times when wildfire smoke is affecting air quality in the region.
