What should you do to stay safe amid wildfire smoke? What health experts suggest

Smoke exposure can trigger severe breathing responses in people with lung diseases. Here’s how to keep yourself safe.

As thick smoke blanketed Metro Detroit on Thursday from wildfires in Canada and Minnesota, health officials are urging residents to take precautions.

Dr. Avani Sheth, chief medical health officer for Wayne County Health, Human and Veterans Services, on Thursday said the best way for residents to protect themselves is to stay indoors in air conditioning, keep windows closed, reduce outdoor activity and check the Air Quality Index before going outside.

“Wildfire smoke at these levels is unhealthy for everyone, and the added heat can place even greater stress on the body,” Sheth said in a press release.

The air quality in southern Michigan reached levels so toxic Thursday morning that it was considered an “emergency condition” by federal environmental officials.

The conditions will last through Friday, according to a Thursday morning update from Michigan Department of Environment, Great Lakes and Energy meteorologists. How long it persists after that is “the big question,” they said.

Wayne County Public Health said warm temperatures are also expected on Thursday. It noted that the combination of heat and wildfire smoke can place additional stress on the body, particularly for older adults, young children, people with chronic medical conditions, outdoor workers and anyone without access to air conditioning.

Who is most impacted by wildfire smoke?

Sensitive groups or those with other underlying conditions are likely most affected by the smoke. That includes those 65 and up, those with asthma and people with cardiovascular disease.

Smoke exposure can trigger severe breathing responses in people with lung diseases.

According to the US Environmental Protection Agency, children up to 18 are also at greater risk of smoke-related health effects, because their lungs are still growing.

“In addition, compared to adults, they are more likely to be exposed to smoke because they spend more time outdoors,” according to the EPA. “Children also engage in more vigorous activity and inhale more air per pound of body weight than adults, both of which affect the dose of smoke they experience and their risk of a health effect.”

What should people do to stay safe?

Wayne County Public Health is encouraging residents to:

  • Stay indoors in air conditioning as much as possible and keep activity levels low.
  • Keep windows and doors closed.
  • Run air conditioning with MERV 13 or higher filters, if available. You can learn more about adjusting your air conditioner at EPA Indoor Air Quality.   
  • If you do not have air conditioning, seek relief at a cooling center or another air-conditioned public location.
  • Wear a well-fitting N95 or KN95 mask when spending time outdoors.
  • Move indoors immediately if you experience coughing, wheezing, chest tightness, shortness of breath, dizziness or burning of the eyes, nose or throat. If symptoms persist or worsen, contact your health care provider.

What if you don’t have A/C but should keep windows closed?

The Michigan Department of Health and Human Services recommends seeking shelter elsewhere if you do not have an air conditioner and it is too warm to stay inside with the windows closed.

The agencies recommends calling or texting 211, or contacting your local health department, to find out if there is a shelter or cooling center nearby. Health officials also suggest considering spending time in an air-conditioned public place such as a library, mall, or movie theater.
