When you take in air through your nose, the following beneficial processes occur:
- Air is warmed and humidified before it hits your lungs.
- The cilia, or tiny hairs, lining your nose trap pathogens, dust, and other foreign particles, acting as a pre-filter before the air reaches your lungs.
- Nerves in your nasal passages (which connect to your hypothalamus in the brain) sense everything about your breathing and use that information to regulate it. When you breathe through your mouth, none of these functions can take place.
So the trick is to minimize these problems by breathing more lightly, and this happens automatically when you shift from breathing through your mouth to your nose. It also slows down and regularizes our breathing and improves oxygenation. Also a calming effect is gained, because it activates the parasympathetic nervous system.
While breathing is a fundamentally natural function of human beings, it can be negatively influenced by many factors of modern living such as stress, sitting at a desk for long periods, and excessive talking. In fact, about 80 percent of the Western population breathes incorrectly. So become conscious as to how you are breathing, for nasal breathing greatly enhances our health in a myriad of ways.
