Buzzline

Researchers from Harvard have established a connection between alarmingly high levels of PM 2.5 air pollution and increased occurrences of heart attacks and strokes in seven significant US cities, which include Los Angeles, Phoenix, Houston, and Chicago. These tiny particles bypass the lungs and cause inflammation in the arteries, elevating the risk of heart attacks by as much as 28% on days with poor air quality. Elderly individuals and those with pre-existing heart conditions face the highest danger. Here’s a daily routine for residents in these impacted areas to safeguard their heart health.
