American Heart Month- The
Environmental Health Connection
The American Heart
Association designates February as American Heart Month. During the month, much effort is spent on helping
the public become aware of the importance of addressing lifestyle factors, like
diet and exercise, keeping blood pressure within the optimal range, knowing the
signs of heart attack, and being able to perform cardio-pulmonary resuscitation
(CPR). All of these factors and more are
important to avoid heart disease and support those who are affected. Heart disease is the number one cause of
death overall for men and women in the United States.
One rarely hears any mention of the role that environmental
exposures play in causing or exacerbating heart disease. Scientists have established that
environmental factors increase the risk of cardiovascular disease. For example, carbon monoxide and ultra-fine
particles that result from combustion and the complex mixture of toxic
chemicals present in tobacco smoke all have been associated with cardiovascular
disease. Sodium, which is a very common ingredient in processed and prepared
food, has been connected with elevated blood pressure. Excessive refined sugar has been shown to be
associated with heart disease risk. Maternal exposure to certain substances in the
environment can increase the risk of birth defects in children.
Other connections between heart health and the environment are
present. For example, we know that
people prefer to be physically active in settings (i.e., environments) that are
clean, well-lighted, safe, and have well-maintained amenities. Regulation of the environment, coupled with
good planning, help to provide places in communities that have healthy places
like parks, trails, schools, and other community facilities. Community blight, neglect, litter,
deteriorated housing, and noise levels foster persistent stress among residents
and contribute to greater cardiovascular risk.
Environmental Health Professionals can and do contribute to
heart health is many ways. They
investigate and evaluate environmental contamination, air pollution, indoor
environments, building hygiene, and food establishments and stores. Environmental Health Professionals work with
community members to identify problems, to improve conditions in neighborhoods
by eliminating places with improperly disposed trash, to help to get stray
animals controlled (who wants to go out and exercise with packs of stray dogs
in the streets?), and to eliminate blight.
Environmental Health Professionals help community members improve
overall environmental awareness. They
work with city planners to plan, design, and oversee the building of new
amenities like parks and trails. They
work with employers to cut down on unnecessary vehicle use by encouraging
walking, bicycling, and transit use, and help to ensure that the risks from
injury are minimized.
The U.S. Environmental Protection Agency has a healthy heart program that
emphasizes the connection between good environment and heart health. EPA also provides the AirNow web page that forecasts local air
pollution levels and lets community members know the when it is safer and
healthier to be active outdoors. The Centers for Disease Control and
Prevention also promotes the connection between healthy environment and
improved heart health and overall well-being.
Public health approaches that address multiple sets of
factors and target multiple levels or domains are the most likely to be
successful. Public health professionals and community members should support
comprehensive approaches that promote healthy lifestyle through awareness,
education, public policy, and improvement of the environment. Support the efforts to improve heart health and
reduce the toll of heart and circulatory diseases throughout the Nation. Good environment and heart health complement
each other nicely!
