Research has revealed air pollution not only damages our lungs but also poses a risk to our hearts.

Prevalent air pollution in urban areas, commonly believed to only harm the lungs, actually harms other vital organ systems as well.
A recent report by the National Health Research Institutes (NHRI) found a strong correlation between air pollution and chronic disease mortality rates. The report tracked the concentration of fine inhalable particles with diameters of 2.5 micrometers or smaller, known as PM2.5, over a decade. A reduction in PM2.5 concentration was linked to decreased mortality from lung cancer, pulmonary obstruction, and ischemic heart disease. The report also found a 7.31 percent reduction in stroke incidence.
PM2.5 particles can enter the body and cause inflammation via microphage activation, leading to vascular blockages, arteriosclerosis, and even ischemic strokes. Cardiologist Dr. Kevin Lin (林謂文) warns that particulate matter may enter the bloodstream through respiration, leading to chronic inflammation throughout the body and in blood vessels, ultimately causing vascular hardening or plaque formation.
National Taiwan University professor Dr. Chen Hsiu-Hsi (陳秀熙 ) states that elderly individuals and those with kidney disease must be particularly cautious about high exposure to PM2.5 in the environment, as it can trigger ischemic heart disease caused by chronic kidney disease.
Not just the elderly are at risk. Research from the NHRI indicates that long-term exposure to air pollution may reduce survival rates in liver cancer patients and increase the risk of three major complications in diabetes patients, including decreased kidney filtration function, retinopathy, and increased proteinuria. Dr. Chen further notes that air pollution is linked with an increased probability of kidney disease.
During periods of poor air quality, it's important to wear masks and to pay attention to fluctuating temperatures that can increase the risk of cardiovascular events. Experts note that high-risk groups should also avoid exercising outside.
