Aaron Hartman, MD explains why nasal breathing is important: the sinuses act as the body’s natural filter and humidifier, nasal breathing slows respiration and helps calm the nervous system, and mouth taping at night can promote nasal breathing and reduce stress-related mouth hyperventilation. The excerpt educates on physiological benefits and a practical intervention.

Your sinuses are your body's natural filter and humidifier for your air, so you should breathe through your nose. And actually breathing through your nose actually helps slow your breathing down. It actually helps calm your nervous system. So just deep breaths through your nose. When people are stressed, they actually will tend to hyperventilate through your mouth. So you can actually also affect your nervous system a little bit by nasal breathing, which, again, mouth taping at night kind of helps with that.
