Eating too much fatty food, exercising too little and smoking
can raise your future risk of heart disease. But there is another
factor that can cause your heart problems more immediately: the air
you breathe.
Previous studies have linked high

ts found that people exposed to high levels of pollutants
(
污染物）were up to 5% more likely to suffer a heart
attack within days of exposure than those with lower exposure. A
separate study of stroke patients showed that even air that the U.
S. Environmental Protection Agency (EPA) considers to be of
“moderate” quality and relatively safe for our health can
raise the risk of stroke as much as 34% within 12 to 14 hours of
exposure.
The authors of both studies stress that these risks are
relatively small for healthy people and certainly modest compared
with other risk factors such as smoking and high blood pressure.
However, it is important to be aware of these dangers because
everyone is exposed to air pollution regardless of lifestyle
choices. So stricter regulation by the EPA of pollutants may
not only improve environmental air quality but could also become
necessary to protect public health.
