A Singapore study found that when the PSI exceeds 100 (Unhealthy range), heart attack cases rise by 9%. For those with chronic heart conditions, the risk is even higher. Fine particles (PM2.5) don't just irritate your lungs—they enter your bloodstream, raising blood pressure, causing inflammation, and promoting blood clots.
