Air Pollution Linked to Higher Risk of Heart disease and stroke

http://healthland.time.com/2012/02/15/air-pollution-linked-to-higher-risk-of-heart-attack-and-stroke/

Hi, after first week of stroke, I was wondering how stroke can be important to our life nowadays. Stroke is one of third leading cause of death and a major cause of disability in our world, especially industrialized countries. Since world is getting developed with new and fascinating technology, there is always something that causes other trouble. Research says that air pollution can be linked to higher risk of heart disease and stroke. According to the research, the risk for healthy people may be relatively low, however, almost everyone breathes polluted air, and there was 34% higher chance to get stroke from patients who were admitted with stroke after a 24-hour period of moderate air quality. This percentage is not very high, but still it is kind of dangerous to the patients who already admitted to stroke once. I really hope this only applies to the huge cities such as L.A., New York City, Chicago, etc where most of pollutants are coming from car exhaustion. Sadly, researchers also found  that the danger was greatest for those exposed to black carbon and nitrogen dioxide, both emitted from fuel-burning car engines. 
I guess going with green is the best way to survive nowadays! :)

  1. I found another article that discusses how drinking diet soda can lead to an increased risk of heart attack and stroke (http://vitals.msnbc.msn.com/_news/2012/02/14/10408624-even-a-few-days-of-air-pollution-may-trigger-heart-attack-stroke). Reading both this article and the above mentioned one got me thinking to as what doesn't have some sort of risk for a medical problem. It seems like almost anything can give you an increased risk for heart attack or stroke, so is it really worth knowing everything that is a risk factor? I'd like to think that everything in moderation would help with this problem, but that is one thing Americans are not good at. Pollution is something that I definitely believe should be dealt with, but how far should we go to know everything that could ever possibly be bad for us? Is it worth it to know?

    1. I agree with Kayla on this one. Clearly air pollutants have many negative effects anywhere from climate change (such a global warming, acid rain, depletion of the ozone layer), health diseases (such as chronic respiratory disease, lung cancer, heart disease and cancer), and even psychological disorders (some try to link pollutant to autism! and other learning disabilities). But with all these negative effects, it should be more of a reason to go green.

      Also I did find the statement "elevated levels of air pollutants typically emitted by cars and trucks could trigger a stoke within hours" to be a bold one. Some typical triggers are heavy physical activity or infection which will cause the vessels to vaso-constricts so this statement is kind of out of the blue. If anything, I would think air pollutants are a gradual and ongoing cause like plaque buildup.

  2. Since the car exhaustion is the main cause for the air pollution, global climate change and various health issues, I wish we all can drive all vehicles via electricity...If we don't go green, the next generations will be in big trouble.
