Air pollution can raise blood pressure

Breathing polluted air for even two hours can boost blood pressure, potentially raising the risk of cardiovascular disease in those who are already vulnerable. Studies have shown that exposure to air pollution, particularly fine particulate matter (PM2.5), can cause inflammation and oxidative stress in the body. These factors contribute to the stiffening of blood vessels, which in turn raises blood pressure. For individuals with pre-existing heart conditions or hypertension, such short-term exposure to polluted air could significantly increase the risk of heart attacks, strokes, and other cardiovascular events. It’s crucial to take steps to limit exposure, such as staying indoors on high-pollution days and using air purifiers where possible.
