Health impacts of smoke, low air quality
Anyone closest to the fire where the smoke is thickest will be at risk for respiratory issues, meteorologist Tammie Souza reports.
If you're in an area where air quality has decreased due to the smoke, you may experience headaches, difficulty breathing, fatigue or irritated eyes, sinuses and lungs.
Members of sensitive groups who are downwind of the smoke should limit their time outdoors and avoid strenuous outdoor activity.
Virtua Health and the American Lung Association say anyone near wildfire smoke should close their windows and turn on the air conditioning.
"The smoke is unhealthy for everyone, and it's especially dangerous for people with underlying respiratory diseases," Virtua pulmonologist Dr. Eric Sztejman said in a statement. "People can experience lung irritation, coughing, and trouble breathing. People may also experience stinging in their eyes and a scratchy throat."
Smoke particles can also trigger asthma attacks, heart attacks and strokes.
Wearing masks, even an N95, may not provide enough protection against the smoke.
