Exercise, a balanced diet, and reduced salt intake are lifestyle changes that can promote heart health.
And a new study suggests that living in less polluted areas may also help prevent the risk of heart disease.
A recent study by the University of Singapore found that tiny air pollution particles known as PM2.5 are linked to a range of health problems and can lead to heart attacks and strokes.
After studying 18,000 cases of cardiac arrest outside the hospital, the team found that 492 of those cases could have been caused by PM2.5. Although this is a small number, it shows the severity of air pollution.
Speaking to Science Alert, epidemiologist Joel Ecke said: “We have provided clear evidence of a short-term association between PM2.5 and out-of-hospital cardiac arrest, a catastrophic event that often results in sudden death.”
“These results show that efforts to reduce particulate air pollution and protection from particulate matter exposure can play a role in reducing the incidence of sudden cardiac arrest in the Singaporean population, as well as reduce the burden on health services,” Icke added. .
While the study was conducted in Singapore, this is not a country-specific problem, but rather a global health crisis.
Pollution levels are rising all over the world, and major cities such as London and Singapore are seeing rising levels of air pollution. This is bad not only for the planet, but also for the cardiovascular system and health services of every country involved.
In addition, new studies are being published showing links between air pollution and a number of deadly diseases.
In the midst of all this, those who are likely to feel the suffocating effects of air pollution are those with heart disease, asthma, or weakened immune systems.
In addition, there are studies showing that air pollution can increase the risk of diseases other than heart attacks, including those associated with carcinogenic lifestyle habits.
And earlier this year, researchers at the Francis Crick Institute found that air pollution can cause lung cancer, even in non-smokers.
After studying data from more than 400,000 people, they found that exposure to a particulate matter known as PM2.5 can promote the growth of cells containing cancer-causing mutations.
While the best way to reduce your risk of lung cancer is not to smoke, there are other ways to reduce your risk.
In the case of the institute’s study, moving out of the city to a place with cleaner air could be a potential way to reduce your chances of developing lung cancer.
A study by Professor Charles Swanton in September showed how air pollution causes lung cancer, stating: “Cells with cancer-causing mutations naturally accumulate with age, but they are usually inactive. We have shown that air pollution causes lung cancer.” “It awakens these cells in the lungs, causing them to grow and potentially turn into tumors.”
Professor Swanton added: “The mechanism we have discovered may ultimately help us find better ways to prevent and treat lung cancer in the absence of smoking. If we can stop cell growth in response to air pollution, we can reduce the risk of lung cancer.” “
Dr. Emilia Lin, co-author of the study, said: “According to our analysis, increased levels of air pollution increase the risk of lung cancer, mesothelioma, and cancer of the mouth and throat. This finding suggests a broader role for cancer caused by inflammation caused by a carcinogen such as air pollution.”
Dr. Lin added: “Even small changes in air pollution levels can affect human health. About 99% of the world’s population lives in areas where annual WHO guidelines for PM2.5 are exceeded, highlighting the public health concerns associated with air pollution during all over the world. world”.
