Breath
James Nestor on nasal breathing, and what modern jaws lost
Nasal versus mouth breathing, slow breathing rates, carbon dioxide tolerance, and how modern diets changed the shape of our airways: a journalistic tour of breathing research. Some of it is speculative, and it is written as narrative rather than review. It is the reason nasal breathing shows up in so many stacks.
