Poor air quality is an important threat to the health of NYC residents. During the summertime, warm weather, along with strong sunshine, can lead to high levels of ground-level ozone, or "smog." Throughout the year, NYC may experience poor air quality due to high concentrations of small — also called fine — particles (PM2.5) found in the air.

Elevated ozone levels can limit a person's ability to take a deep breath, and can trigger symptoms such as coughing, throat irritation, and breathing discomfort. Children and people with respiratory diseases, such as asthma, can be sensitive to the effects of ozone, and even healthy adults who work or exercise outdoors can experience the unhealthy effects of ozone pollution.
Fine particle (PM2.5) air pollution has been linked to worsening of many serious health problems including heart and lung diseases, cardiac arrhythmias, heart attacks, asthma, and chronic bronchitis. People with heart or lung disease, older adults, and children are especially at risk when levels of fine particles are elevated.
Know if you have a health condition that makes you especially sensitive to air pollution.
Spend less time outdoors and in strenuous physical activity on poor air quality days. Plan outdoor activities when pollution levels are lower, and try to avoid exercising near busy roadways.

Reduce energy use at home and at work. Conserve electricity and heating fuel. Set your air conditioner thermostat to 78 degrees or low cool and lower your heat thermostat in winter. For useful tips on saving energy – and money - visit GREENYC and EPA
Choose a cleaner commute - car-pool, use public transportation, bike or walk when possible. Biking and walking are a great way to get exercise daily. To get more information on biking resources available in NYC, visit the NYC Department of Transportation.
