As per the U.S. study, heart diseases are more common for people staying in heavy traffic exhaust. The fine particles in more traffic congested areas lead to lowering down the level of good cholesterol which is essential for a healthy blood flow.
The high-density lipoprotein helps in lowering down the probabilities of heart ailments thereby removing the wreckages from the blood vessels and curbing the level of dangerous fats. These dangerous fats or triglycerides make blood thicker, gummier and more clot prone.
The study was carried out on 6,654 adults and figured out that people who are more exposed to high levels of traffic pollution particles have lesser levels of HDL cholesterol in their blood.
The earlier research has indicated a linkage between traffic exhaust and an increased danger of lung damages and breathing issues also resulting in cardiovascular strokes as well.
The recent study focused on the combination of solid particles and liquid droplets smaller than 2.5 micrometers in diameter or else called PM 2.5. These particles can include dust, dirt, soot and smoke. Black Carbo which is a component of pollution particles framed by kinds of fuels was also taken into consideration.
The participants of the study were on an average 62 years old while half of them were existing or past smokers. Approx. 16 percent of the participants were prone to taking cholesterol-lowering drugs. Roughly 45 percent had high blood pressure.
The researchers also considered the blood levels of HDL cholesterol and other HDL particle count. The HDL cholesterol over a year was found in lesser quantity in people who were more exposed to black carbon than with people who were exposed lesser.
The study wasn’t a controlled experiment designed to prove how traffic fumes directly influence cholesterol or the risk of heart disease.
