Breathing Lessons

An authoritative, accessible guide to how our lungs work and how to protect them Most of us pay little attention to the workings of our lungs but the COVID-19 pandemic has sparked interest in their functioning and fear about the risks they face. Dr MeiLan K. Han, a leading pulmonologist and a national spokesperson for the American Lung Association, takes readers on a fascinating tour of this most vital organ. Han explains the wonder of breathing and reveals how the lungs serve as the body’s first line of defence. She provides a timely overview of the latest scientific thinking about the leading respiratory risks—including indoor and outdoor pollution, smoking and vaping, wildfire smoke and viruses like SARS-CoV-2—and offers a practical guide to keeping lungs healthy. With authority as both practitioner and medical researcher, she argues powerfully for a social policy that makes a priority of preserving lung health nationwide.
