Air Quality Alert In New York City: How to Stay Safe During Extreme Heat and High Pollution
A pulmonary and critical care medicine expert shares what to know about heat and air quality index level, and how to reduce your risk during air quality alerts.
New York City, Long Island and parts of the Hudson Valley are under a heat advisory and air quality alert that extends until Tuesday night. The combination of extreme heat and poor air quality can pose health risks for children, older adults, and those with underlying conditions.
Air Quality Indexes (AQI) span from 0 to 500, and the higher the number, the greater the air pollution and potential health risks. The AQI in New York City and surrounding suburbs is expected to exceed 100, according to the advisory.
“The air quality index is a good thing to monitor, as some people are more sensitive to pollution and heat,” says Dr. Michael S. Niederman, a physician specializing in pulmonary and critical care medicine at NewYork-Presbyterian/Weill Cornell Medical Center and a professor of clinical medicine at Weill Cornell Medicine. “Being mindful of your own susceptibility, especially if you have underlying cardiovascular or lung conditions is important. Take extra precautions when you’re outside, limit strenuous outdoor activity, and stay in air conditioning if possible.”
With warmer weather ahead, Dr. Niederman offers simple tips to stay safe in high heat and poor air quality.
How is air quality measured and what is a typical healthy average?
Dr. Niederman: Air quality is a measure of the concentration of particulate matter and gases in the ambient air.
- Air Quality Index below 50: Good air quality
- Air Quality Index above 100: People are more likely to develop symptoms
How can you protect yourself when there is poor air quality and extreme heat?
Dr. Niederman: Taking proactive precautions is essential to protect your health, especially if you find yourself more symptomatic when you go outdoors.
To reduce your risk:
- Limit outdoor activities
- Postpone outdoor events
- Use air conditioning with filters
- Wear a mask
- Don’t smoke
- Limit indoor pollutants, such as candles
Who is most at-risk during air quality alerts?
Dr. Niederman: Extreme heat increases cardiovascular demands on the body, and poor air quality can double stress on people.
Those most at risk include:
- Older adults
- Infants and young children
- People with underlying conditions, such as heart and lung diseases
Those with lung disease are particularly at risk, including those with:
- Asthma
- Emphysema
- Pulmonary fibrosis
How long do air quality alerts last, and what should you do?
Dr. Niederman: At this moment, we want to follow state and city public health announcements and air quality measures, such as through AirNow.
Even healthy people may develop symptoms such as chest tightness, cough, wheezing, and shortness of breath. Call your doctor if symptoms are persistent and bothersome.
The Air Quality Index, Explained
The six categories of air quality, according to AirNow:
- Green (good, 0 to 50): Air is satisfactory, and air pollution poses little or no risk.
- Yellow (moderate, 51 to 100): Acceptable, but there may be a risk for some people, such as those who are sensitive to air pollution.
- Orange (unhealthy for vulnerable groups, 101 to 150): Sensitive groups may experience health effects. The general public is less likely to be affected.
- Red (unhealthy, 151 to 200): Some members of the general public may experience health effects. Members of sensitive groups may experience more serious health effects.
- Purple (very unhealthy, 201 to 300): The risk of health effects is increased for everyone.
- Maroon (hazardous, 301 or higher): Health warning of emergency conditions: everyone is more likely to be affected.
