Chicago Area Under Air Quality Alert as Heat Persists

CHICAGO,IL – Teh Chicago metropolitan area remains under an Air Quality Alert today as lingering smoke from Canadian wildfires impacts the region,though conditions have improved slightly compared to Monday. Temperatures soared into the low 90s Tuesday, accompanied by high humidity, creating heat index values in the mid-90s across many locations.

During thes alerts, its recommended to limit prolonged outdoor exertion, keep windows closed, and consider using air purifiers. The presence of wildfire smoke introduces fine particulate matter (PM2.5) into the air, which can penetrate deep into the lungs and bloodstream.

Heat Safety Tips:

Experts advise staying hydrated by drinking plenty of water, seeking air-conditioned environments, and avoiding strenuous activity during peak heat hours.
