Wildfire smoke can be harmful to your health, especially if you already have chronic hearth and lung diseases. The CDC recommends when there is brushfire smoke in the area to: 

"Keep indoor air as clean as possible if you are advised to stay indoors. Keep windows and doors closed. Run an air conditioner, but keep the fresh-air intake closed and the filter clean to prevent outdoor smoke from getting inside. If you do not have an air conditioner and it is too warm to stay inside with the windows closed, seek shelter in a designated evacuation center or away from the affected area."

From the Source:

"Government officials have cautioned people about air quality in a region that is usually known, especially at this time of year, for pristine cobalt skies.

But that has not been the case since last week, as the Pacific Northwest has been inundated by plumes of smoke from Canada, where more than 20 wildfires are blazing. The region has also contended with record-breaking temperatures on some days."

"Harborview Medical Center in downtown Seattle, part of UW Medicine, has seen 'an increase over the past week in exacerbations in people who have chronic obstructive pulmonary disease, which includes emphysema, and also in people who have asthma,' Leila Gray, a spokeswoman for the hospital system, said in an email on Monday evening."
