The 'very unhealthy' air quality poses significant health risks to all individuals, especially sensitive groups like children, older adults, and those with heart or lung conditions. Symptoms such as shortness of breath, coughing, and dizziness have been reported. Outdoor activities are strongly discouraged, and the city has made free KN95 masks available at NYPD precincts, public libraries, and select firehouses. The smoke has also disrupted events, including the Mets-Phillies game in Philadelphia, which was rescheduled due to poor air quality.
