Clean air can lead to healthier heart, Study

In a study done by China, better air quality can translate to a reduction in cardiovascular risks, most especially in people with heart problems.

Despite not directly saying that air purifiers could help with the issue of air quality, and also not directly connecting air purifiers with the prevention of some  major cardiovascular problems, the research does show a reduction in risk when young adults were exposed to “fresh” air.

For the study, Dr. Ang Zhao and Dr. Renjie Chen from Fudan University in Shanghai, China placed a real or fake purifier in the rooms of 35 health college students for a time of 48 hours. After two weeks, the participants were asked to try the purifiers again, but this time the air purifiers were switched.

According to the results, students who were staying in rooms with real air purifiers were at a lower risk of inflammation and blood clotting, showed improvements in lung function, and had better blood vessel constriction with lower blood pressures. Also, the air pollution the rooms lowered by 56% to 40 micrograms from 96 micrograms.

According to study co-author and cardiologist Dr. Sanjay Rajagopalan “In countries of the world where air pollution is a problem, I think this would be especially important.”

The World health Organization states that air must contain less than 35 micrograms of miniscule air particles for it to classify as “not polluted.” However, air pollution in major Asian cities range from 100 to 500 micrograms per cubic meter. This is According to Rajagopalan’s paper.
