The air we’re breathing in New York is so polluted it might increase our risk of stroke by almost 25%, according to a new study released by the NYU Langone Center on Wednesday. The study conducted cardiovascular screenings tests for 300,000 residents in the tristate area and concluded that “inhaling New York air can block arteries to the brain,” according to the New York Daily News.

The study is centered around the prevalence of fine particle matter, often caused by combustion. The news is most concerning for people who already have health issues. Newman’s recommendations are to “stay inside” (great) and to “lobby for cleaner air.”

The city’s most polluted air is surprisingly located in the some of the richest New York neighborhoods: Gramercy and Chelsea, where the air is 18% and 9.5% higher than federal standards, respectively.
