Why? Internally to the face the nasal cavity is massive and largely not restricted, especially compared to the throat (pharynx) which is restricted and can accept only small volumes of air at a time. Because of that the body must work substantially harder to permit large air volumes through mouth breathing.
Just search google images for "pharynx". The visual difference in size is striking.

Just look at the internal structure of the nasal cavity. It's a sensory organ and designed to maximize surface area contacting the air. In other words, it's full of obstructions that intentionally reduce airflow Your thesis here is nonsense. You can't change a downstream restriction by changing conditions upstream. If anything, adding restriction is probably what helps. By restricting airflow upstream of the lungs, you create a partial vacuum within the lungs which probably substantially alters the conditions for gas exchange. A partial vacuum probably greatly enhances CO2 rejection from the blood, but I'm not a biochemist.
- austin-cheney 2y agoI take it you invented some baseless conjecture. As a casual suggestion try searching the web for "mouth versus nose breathing" and see what the results say. One of my biggest complaints about software developers is that so many claim to be engineers, but instead of measuring things (which is what engineers do) so many invent their own conclusions that tend to be wrong almost every time. It's disappointing.
