If you thought that the simple act of breathing couldn’t do you any harm, a new study comes to ruin your expectations. The research in question, which was done on data from people from Singapore, suggests that increased concentrations of small particles in the air can lead to cardiac arrests.
The data collected in order to obtain the shocking results were gathered over a period of almost a decade (between 2010 and 2018), according to ScienceAlert. PM2.5 particles (2.5 micrometers in diameter) have been under the spotlight for the new research, and they are small enough to be inhaled with ease.
Joel Aik, an epidemiologist from the Duke–NUS Medical School of the National University of Singapore, stated:
We have produced clear evidence of a short-term association of PM2.5 with out-of-hospital cardiac arrest, which is a catastrophic event that often results in sudden death.
The same scientist declared:
These results make it clear that efforts to reduce the levels of air pollution particles in the 2.5 micrograms or lower range, and steps to protect against exposure to these particles, could play a part in reducing sudden cardiac arrests in Singapore’s population, while also reducing the burden on health services.
The statistics show that over the course of just a year, 350,000 people from the US die as a result of cardiac arrest. Also, 9 out of 10 people who go through a cardiac arrest outside the hospital will die.
After the new study, the need to tackle air pollution levels has become even more urgent. The research was published in The Lancet Public Health.
