Pollution in big cities has a major adverse effect on people’s cardiovascular health. Recent studies have revealed that residing in a city with high pollution stats can have major detrimental effects on one’s overall health. However, one area of the body that is most affected is the cardiovascular system. Inhaling fine dust particles present in the air can not only cause breathing trouble and reduced blood flow, it can also lead to major fatal illnesses such as heart attacks and myocardial infarctions. A German study conducted recently have shown that breathing high levels of traffic exhaust can lead to an increased risk of atherosclerosis, or hardening of arteries, which can in turn increase the propensity of developing heart attacks. When people jog or go for long brisk walks during heavy traffic hours, they are doing their hearts more harm than good. While it is true that jogging is a great exercise for the heart, inhaling car fumes is definitely not so, and yet many people fail to take this into consideration while they strive hard to keep themselves fit. Jogging leads to heavier breathing which increases the need for oxygen intake. Instead of getting fresh oxygen in such times, if a person is exposed to car fumes, then he or she is prone to take in more pollutants than in other times. This certainly hampers one’s physical health in more ways than one. People should always avoid taking part in outdoor activities during the hours of high air pollution as it may cause reduced flow of blood to the heart because of labored breathing. This can eventually lead to cardiac arrhythmia, cause a heart attack and even result in a sudden death. Moreover, people affected by heart diseases like angina are more vulnerable to the adverse effects of city air pollution. Angina is a condition that is caused by reduced flow of blood to the heart, and can also be further accentuated by air pollution. This can lead to further reduction in flow of blood, nutrients and oxygen that the heart requires to function properly. The air that a person breathes passes on to the lungs and then oxygenates the blood which is then circulated to the heart. This blood then passes on to the heart, from where it is pumped to the other parts of the body. Hence it is of utmost importance that one takes in only clean air, as impure, polluted air can disrupt the entire circulatory system of a person. The city pollution has become major concern these days due increase in number of vehicles, industrial emissions etc.
