Researchers have long proven emissions from cars, trucks, coal plants reduce air quality and affect our health. Yet another study documents the serious health impacts on all of us, specifically our heart and arteries.
The evidence is stronger than ever that pollution from industry, traffic and power generation causes strokes and heart attacks, and people should avoid breathing in smog, the American Heart Association said on Monday.
Particulate matter appears to directly increase risk by triggering events in susceptible individuals within hours to days of an increased level of exposure, even among those who otherwise may have been healthy for years,” said Dr. Robert Brook of the University of Michigan in Ann Arbor, who headed the group writing the report.
A review of six year’s worth of medical research also showed strong evidence that pollution can help clog arteries, and a “small yet consistent” association between short-term exposure to air pollution and premature death.

The group recommends that the elderly or anyone with heart disease, high blood pressure, high cholesterol, or diabetes should pay attention to air pollution and air quality index warnings.
“People can limit their exposure as much as possible by decreasing their time outside when particle levels are high and reducing time spent in traffic — a common source of exposure in today’s world,” Brook said.
Yet another powerful reason to beat our addiction to fossil fuels. You’ll find plenty more here in my original articles — Stephen
