WISCONSIN (CIVIC MEDIA) – The poor air quality in Wisconsin this week continues as wildfires stemming from Canada continue to affect the state.

Primary pollutants in the air are at an unhealthy level due to wildfire smoke across much of the state. The Air Quality Index (AQI) utilized by the National Weather Service (NWS) is at the “Unhealthy for sensitive groups” or “Unhealthy” level for various parts of the state, with areas in central and east Wisconsin being affected the most.

Sensitive Groups

According to a press release from the Wisconsin DNR, “People with heart or lung disease, older adults and children should consider making outdoor activities shorter and less intense and reducing heavy exertion. Consider rescheduling or moving events indoors.”

The best way to protect yourself from wildfire smoke is to keep track of your local air quality. Stay indoors with your doors and windows closed. Avoid activities that increase your indoor air pollution. This includes activities like vacuuming, frying food, burning candles, or using gas-powered appliances. You can install a high-efficiency air filter in your home. If you have to be outdoors for longer periods, use an N95 mask.

For Everyone

NWS advises residents to keep outdoor activities shorter and less intense. Officials recommend going inside if you have symptoms such as coughing, wheezing, or shortness of breath. Unhealthy air quality can also cause irritation of the eyes, nose, and throat. Sensitive groups should consider moving all activities inside. You can check the current air quality by visiting the Wisconsin Department of Natural Resources website.
