Those of you who have been with me for a while know how concerned I am about environmental pollution and the negative affect it can have on your heart. Now a new study published in the British Medical Journal once again reinforces just how dangerous pollution is. What they found is that high pollution exposure significantly increases your risk of having a heart attack for six hours.
This large-scale study, which was conducted by researchers from the London School of Hygiene and Tropical Medicine, followed 79,288 people in the United Kingdom who had a heart attack between 2003 and 2006. They measured the traffic pollution in the areas where each participant lived—including ozone, carbon monoxide, nitrogen dioxide, and more. What they found is that significant pollution exposure upped the risk of a heart attack for six hours.
This isn't surprising since breathing polluted air impacts your cardiovascular system. After all, it's through your lungs that your heart receives its life-sustaining oxygen. Air pollutants that you breathe can become lodged in your lungs, leaving them prone to infection and distress. Also, impaired lungs put undue stress on your cardiovascular system. In fact, air pollution is so dangerous that it can negatively impact even those of us without heart or lung vulnerabilities.
This isn't the first study linking airborne pollutants and heart disease:
Fortunately, there are a lot of things you can do to limit your exposure to pollution:
1. On hot humid days, try to stay indoors, close the windows, and use a fan or an air conditioner. If you have an air conditioner, remember to clean or replace your filter at least every six months since faulty, contaminated air conditioning filters can cause respiratory illnesses.
2. On "clean air days," when pollen counts are low and the air is clean (relatively speaking, of course), open your windows and doors to air out dust, molds and other chemicals that have accumulated over the winter months.
3. Invest in an air filter. Not only will it clear the air of thick, dense particles, it will filter out low-micron particles, dust mites, molds, pollens, allergens and animal dander. A good system, such as the HEPA (be sure to get a true HEPA, not a system advertised as "HEPA-like"), should filter at least 99.9% of dust particles as small as .3 microns from the air.
4. Cleanse your system from the inside with vitamin E (100 to 200 IU for women, and up to 400 IU for men) which protects the lungs from excessive auto emissions and ozone, vitamin C (300 to 500 mg) which is a powerful antioxidant, beta carotene (7,500 to 10,000 IU) which protects the lungs, quercetin (100 mg) to combat environmental allergens, and CoQ10 (100 to 200 mg) to stabilize membranes and round up harmful free radicals.
5. Practice Earthing, either by going barefoot outside or sitting or lying on a special conductive device, such as pads for the floor or bed. Connecting to the Earth like this helps to support heart rate variability.
