Smog Could Increase Risk Of Fatal Heart Attacks

It should come as no surprise that living in an area with poor air quality isn’t going to be good for your health.

 

But a new study out of Sweden suggests that the long-term effects could be more alarming than initially believed.

 

It found that while there didn’t appear to be a greater overall risk of heart attack for people exposed to pollutants over a 30-year period, there did seem to be an increased threat of fatal heart attacks specifically.

 

The study, which reviewed information on pollution exposure for 1,397 men and women living in Stockholm County who’d suffered heart attacks for the first time between 1992 and 1994, found that pollution exposure could cause chronic inflammation and hasten the progression of atherosclerosis (hardening of the coronary arteries).  

 

Disturbingly, the research found that people who’d ever lived in pollution-heavy areas had a 40 per cent increased risk of fatal heart attack.

 

Air pollution is believed to have a number of heart health effects. It causes chronic inflammation and increased blockage of the blood vessels, which can lead to decreased heart function.

 

The other risk factors for heart attack like diet, smoking and high blood pressure are probably more important than smog, but still it’s a good idea to minimize your exposure to air pollution. Here are some suggestions about how to keep away from the bad air.

To reduce your exposure to smog and its potential health effects:

• Check the Air Quality index in your community, especially during “smog season” from April to September. Tailor your activities accordingly.
• Avoid or reduce strenuous outdoor activities when smog levels are high, especially during the afternoon when ground-level ozone reaches its peak. Choose indoor activities instead.
• Avoid or reduce exercising near areas of heavy traffic, especially during rush hour.
• If you have a heart or lung condition, talk to your health care professional about additional ways to protect your health when smog levels are high.

To help reduce the overall levels of smog in the air:

• When possible, use public transportation instead of your car. You could also walk or ride your bicycle, as long as smog levels are not too high.
• Look for alternatives to gas-powered machines and vehicles. Try a rowboat or sailboat instead of a motorboat or a push-type lawnmower instead of one that runs on gasoline.
• Consider fuel efficiency when you buy a vehicle. Keep all vehicles well maintained.
• Reduce energy use in your home. Learn more about alternative energy resources.
• Do not burn leaves, branches or other yard wastes.
• Consider joining a citizens’ committee to advocate for cleaner air in your community.
• Spend time talking with your children about the importance of a sustainable lifestyle.
