Health Risks and Protective Measures Urged

Northern Illinois residents with asthma, chronic lung disease, children, and active outdoor adults are being advised to take precautions when air quality is diminished.

Symptoms like wheezing, coughing, fatigue, or shortness of breath may get worse under the current air conditions, and medical professionals recommend avoiding strenuous outdoor activity, but you should seek medical attention if symptoms worsen.

To help reduce emissions, the Illinois EPA urges residents to limit driving, avoid gasoline-powered lawn equipment, conserve energy, and use eco-friendly products.

When Action Days are in effect, businesses and community members are encouraged to spread awareness and adjust their daily habits to protect public health.
