one more reason to strive hard to win pure air to breathe in. Air pollution triggers more heart attacks than most other risk factors,
It is well known that heart attack is triggered by various factors, such as physical
exertion, stressful events, heavy meals, or increases in air pollution. A recent study compared triggers of heart attack at an
individual and population level.
findings that were published in the
suggest that air
pollution triggers more heart attacks than using cocaine. It poses as high a
risk of setting off a heart attack as alcohol, coffee and physical exertion.
Sex, anger, marijuana use and chest or respiratory infections are other major
risk factors. However air pollution which is a population-wide factor is the
major culprit. Though more dangerous, factors like drug use are relatively
rarer. Polluted air should be taken more seriously.
to the World Health Organization (WHO) around 2 million premature deaths worldwide
every year occur due to air pollution.
It is undoubtedly a major
environmental risk to health. Air pollution in many major cities in Asia
exceeds the WHO's air quality guidelines.
major mistake that physicians make is that they always look at individual
patients rather than expanding their thoughts to a population level. Low risk
factors like air pollution hence rarely get attention since they do not look
important at an individual level.

people are exposed to (it),"

study that combined data from 36 separate studies is of great significance as
it calls in for a change in outlook with respect to assessing risk factors. Authorities may start thinking seriously
about strengthening efforts to ban smoking in public places.
