Cleaner Air Means Healthier Hearts

February is Healthy Heart Month. There’s no better time than now to learn how to protect your heart.

Air pollution can affect heart health, and even trigger heart attacks and strokes. That’s important information for the one in three Americans who have heart disease, and for the people who love them.

And it’s why EPA is working with other government agencies, and with private and nonprofit health organizations, on the Million Hearts® national initiative to prevent 1 million heart attacks and strokes by 2017. This month, and every month, we want to make sure people understand how heart disease is linked to air pollution – and what people can do to protect themselves.

Scientific studies, including research by EPA scientists, shows that there’s not just an association between air pollution and heart disease, but that this association can have life-threatening consequences.

In a recent study in Environmental Research, EPA scientists looked at data from NASA satellites and EPA ground-based air monitors, and confirmed that heart disease and heart attacks are more likely for individuals who live in places with higher air pollution.  The study found that exposure to even small additional amounts of fine particle pollution averaged over a year could increase a person’s odds of a heart attack by up to 14 percent.

So, what can you do to help keep your heart healthy?

  • You can start by making sure to eat nutritious meals and exercise (just make sure to check with your health care provider first).
  • Check the Air Quality Index every day to learn about your local air quality and how can reduce your exposure to air pollution.
  • And we can all do our part to make choices that are better for the environment and our health – like taking public transit more often and driving cleaner vehicles.

This February, and every month, remember that cleaner air means healthier hearts.
