In this instructional segment, Dr. Anne Truong explains why breathing both in and out through the nose is beneficial. She highlights that nasal inhalation generates more nitric oxide—a molecule that supports vascular health—while nasal exhalation reduces the amount of carbon dioxide expelled compared to mouth breathing. Conversely, mouth breathing yields less nitric oxide and leads to higher carbon dioxide loss on exhalation, which can be suboptimal. The speaker advises consistently using the nose for both inhalation and exhalation to maximize nitric oxide production and better regulate carbon dioxide levels.

Now, when you breathe in to the nose, you also want to breathe out to the nose, because when you breathe out to the nose, you don't breathe as much carbon dioxide. Because when we breathe in, we want to breathe in oxygen. When we breathe out, we want to get rid of the carbon dioxide. When you breathe in through the mouth, you actually don't make as much nitric oxide. But then when you breathe out to the mouth, you tend to breathe out more carbon dioxide. And sometimes breathing more carbon dioxide. Not too good either.
