    Love the air 
    Feb 14, 2022 - This Valentine’s Day, let's give a little love to our air and start a healthy habit that is good for your heart and lungs. Air pollution, in the form of fine particulates, can travel into the bloodstream, damage blood vessels, and ultimately impact blood pressure and heart function. In addition, the COVID-19 pandemic has shed light on the importance of lung health and reducing air pollution is essential for maintaining it, especially for the most vulnerable populations. According to the American Lung Association, higher levels of air pollution can contribute to worse health outcomes from COVID-19, including higher death rates.
