While some of these risks are unavoidable, others can be mitigated by making simple changes to your lifestyle. One risk factor that is often overlooked is our environment.

A new study published in the journal PLOS ONE recently posted findings on the environmental impact on health. Personal and environmental health data was collected from 50,045 poor, rural villagers living in the northeast Golestan region of Iran. All participants had annual visits with researchers dating as far back as 2004. All were over the age of 40 at the beginning of the study.


The study showed that exposure to above-average outdoor air pollution levels increased the risk of death by 20% and the risk of death from cardiovascular disease by 17%. It specifically found that one-third of study participants who lived within 500 meters (1,640 feet) of a major roadway had a 13% increased risk of death.

Using kerosene or wood-burning stoves (not properly ventilated through a chimney) to cook food or heat the home also increased the overall risk of death by 23% and 9%. Researchers also found that it increased cardiovascular death risk by 36% and 19%. Living far from specialty medical clinics and busy roads also increased the risk of death.

It’s one of the first studies of its kind to identify environmental factors that pose a risk to heart and overall health. It also adds much-needed scientific evidence from people in low- and middle-income countries. Previous research has mostly favored urban populations in high-income countries with much greater access to modern health care services.

“Our study highlights the role that key environmental factors of indoor/outdoor air pollution, access to modern health services, and proximity to noisy, polluted roadways play in all causes of death and deaths from cardiovascular disease in particular,” said study senior author and cardiologist Rajesh Vedanthan, MD, MPH.


Previous studies have found that environmental factors such as air pollution can affect risks of high blood pressure, diabetes, and smoking. However, this new study adds to the dangers by examining the relationship between the environment and the chance of death from heart attack and stroke.

Heart Health

This study adds to mounting evidence of how the environment can affect cardiovascular health. Still, whether you live near a polluted area or not, it is important to take care of your general health.

Heart Rescue is an excellent way to help support and promote cardiovascular health using a variety of ingredients, including omega-3 fatty acids and CoQ10. The omega-3 fatty acids play an important role in cardiovascular function, while CoQ10 is involved in energy production at the cellular level. These two heart superstars are supported by 5 other ingredients to help promote and support cardiovascular function as you age. This formula’s health benefits can help strengthen the heart muscle, support circulation, and help reduce the risk of heart disease.

Sarah began her interest in nutritional healing at an early age. After going through health problems and becoming frustrated with the conventional ways doctors wanted to treat her illness (which were not working), she took it upon herself to find alternative treatments. This led her to revolutionize her own diet to help her get healthier and tackle her health problems. She began treating her illness by living a more balanced lifestyle through healthy food choices, exercise and other alternative medicine such as meditation. This total positive lifestyle change led her to earn a diploma in Nutritional Therapy from Health Sciences Academy in London, England. Today, Sarah enjoys helping others by teaching healthy lifestyle changes through her personal consultations and with her regular contributions to the Doctors Health Press. Also, passionate about following her dreams in life, Sarah moved to France and lived in Paris for over 5 years where she earned a certification in beadwork and embroidery from Lesage (an atelier owned by Chanel). She then went on to be a familiar face sitting front row and reporting from Paris Fashion Week. Sarah continues to practice some of the cultural ways of life she learned while in Europe. They enjoy their food, and take the time to relax and enjoy many of life’s little moments. These are life lessons she is glad to have brought back home with her.
