American Heart Month: Taking Action to Protect Our Health
February is American Heart Month! To help spread the word about heart health, EPA scientists and staff will write each week about the Agency’s Green Heart effort to educate the public about of the connection between air pollution and your heart. Be sure to check back each week to learn more, and for tips on what you can do to stay healthy!

It’s February and Heart Month has arrived and with it a reminder to think about what we can all do to stay well and keep our hearts healthy. As a cardiologist, the month-long focus on the heart gives me a great opportunity to share information with my patients—and now hopefully with anyone who reads this blog—on how they can protect their hearts. It also reminds me to think about the things I do that can hurt or help my heart.
Heart disease remains the number one cause of death in the U.S. for men and women. Less than one percent of Americans have ideal heart health and about 26.5 million have some type of heart disease.
But there are things we can do both individually and collectively to help our hearts. The Global Burden of Disease 2010 study recently published in the medical journal The Lancet describes 67 key factors affecting disability and death in North America. Among the top 20 risk factors, 19 are directly related to individual behavioral or lifestyle choices such as diet, exercise or smoking; or the consequences of those choices.
The remaining risk factor in the top 20 is not associated with individual lifestyle choices, but is more a consequence of our collective actions, namely what we do as a society that leads to air pollution. Air particle pollution (also known as soot) in particular is ranked as the 14th most important.
While in general we have little personal control over air pollution where we live, work and play, there are things we have done as a society that can have lasting positive impacts. The Clean Air Act, for example.
The Act strives to ensure that all Americans are breathing healthy air. Research by EPA and others shows that improved air quality leads to healthier and longer lives. And thanks in large part to that research, the Agency recently strengthened the annual health standard for fine particle pollution (PM2.5) (from 15 to 12 micrograms per cubic meter) to make our air cleaner and healthier.
While EPA continues to work to keep your air clean, there are steps you can take to reduce your personal exposure to air pollutants. For one, don’t smoke and avoid the smoke of others. Second, if you have heart disease consult the Air Quality Index (AQI) as part of your daily routine. The index provides information on air quality and how to avoid unhealthy exposures when air pollutants are high. Simple things like limiting or avoiding exercise outside during high pollution days can help to protect your health and your heart.
So keep in mind during this month of the heart, healthy lifestyle choices including a healthy diet and regular exercise, keeping an eye on your local air quality report, and supporting actions to support clean air are all things we can do for a healthy heart.
