Emphysema is one of the two major forms of Chronic Obstructive Pulmonary Disease (COPD), which comes about when the alveoli become damaged. Those are the tiny sacs in the lung that exchange oxygen into the blood and carbon dioxide out.

In order to keep your lungs healthy, there are a variety of things that you should and should not do. As is usual when talking about such things, smoking is inevitably the first thing that springs to everybody’s mind, but avoiding cigarette smoke is not the be all and end all of keeping a healthy pair of lungs although giving up the evil weed can be a big help. Many other lifestyle choices can have an influence on lung health, as well.
