It became a {{Tooltip|New York Times bestseller}} and a {{Tooltip|Washington Post Notable Nonfiction Book of 2020}}, and—according to the publisher—has sold more than three million copies in 44 languages. <ref name="PRH2020" /><ref name="WPostNotable2020">{{cite news |title=50 notable works of nonfiction in 2020 |url=https://www.washingtonpost.com/entertainment/books/50-notable-works-of-nonfiction-in-2020/2020/11/16/37f4c4de-2069-11eb-b532-05c751cd5dc2_story.html |work=The Washington Post |date=19 November 2020 |access-date=19 October 2025}}</ref>

 

== Part I – The experiment ==

 

👄 At {{Tooltip|Stanford’s Department of Otolaryngology—Head & Neck Surgery}}, the team runs a two-phase, 20-day trial to stress-test the airway. Phase I lasts ten days: Nestor and fellow participant {{Tooltip|Anders Olsson}} plug their noses and breathe only through their mouths while keeping daily routines unchanged. Olsson flies roughly 5,000 miles from {{Tooltip|Stockholm}} and pays more than $5,000 to join. Before starting, Nayak maps the passages with endoscopy and imaging, then the clinic collects baseline measures: blood gases, inflammatory markers, hormones, smell tests, {{Tooltip|rhinometry}}, and pulmonary function. A deep swab taken at the outset tracks how obstruction alters the {{Tooltip|nasal microbiome}} across the ten days. Between phases, they repeat the same panel, comparing mouth-only with nose-only results under the same sleep, meals, and exercise. Within days of mouth-only breathing, tissues dry, soft structures collapse at night, and inflammation rises—changes that appear in lab measures. When Phase II switches to nasal breathing with basic drills, airflow and pressure stabilize and many changes reverse. Within days, the pathway you choose—mouth or nose—reshapes physiology. {{Tooltip|Nasal resistance}}, humidification, and filtration create pressure and chemistry a mouth cannot match, protecting blood gases, airway tone, and microbial balance.

 

== Part II – The lost art and science of breathing ==

 

🦷 Walk the {{Tooltip|Paris Catacombs}} and you’ll see roomy dental arches in skulls stacked along the tunnels; then compare them with the narrowed jaws common today—a visual record of how softer, industrialized food changed faces. Research from {{Tooltip|University College Dublin}} suggests crowding and {{Tooltip|malocclusion}} surged around the first farmers roughly 12,000 years ago, when diets shifted and chewing loads fell. In the 1930s, dentist-researcher {{Tooltip|Weston A. Price}} reported wide arches and straight teeth in traditional societies, then documented how processed staples correlated with shrinking jaws and airway problems; in laboratory work he examined more than a thousand ancient skulls without finding the modern pattern of crooked arches. The mechanism is mechanical: bones remodel under load; when chewing is hard and frequent in childhood, the palate widens and the nasal airway grows with it. Modern orthodontics can expand palates and improve airflow, but daily habits still matter—tougher foods and mindful chewing provide the growth signals appliances try to mimic. Form follows force: what and how we chew shapes the airway because sustained {{Tooltip|masticatory load}} stimulates bone growth in the {{Tooltip|maxilla}} and {{Tooltip|mandible}}, creating space for teeth and the nose—and space to breathe.
