How Proper Breathing Transforms Health, Performance, Sleep, and Even Your Face
Joe Rogan interviews author James Nestor about his book *Breath*, exploring how modern humans have largely forgotten how to breathe in ways that optimize health and performance.
They discuss the science-backed benefits of nasal breathing versus mouth breathing, including impacts on endurance, blood pressure, sleep apnea, asthma, and anxiety.
Nestor explains how facial structure, diet, and orthodontics influence airways and breathing, and shares experiments—from taping mouths at night to expanding the upper palate—to restore better function.
The conversation also covers powerful breathwork modalities (Wim Hof, Tummo, Kriya, holotropic breathing) that can alter physiology, nervous system activity, and even subjective consciousness.
Key Takeaways
Prioritize nasal breathing for everyday life and exercise.
Breathing through the nose filters, humidifies, and conditions air, produces nitric oxide, and can deliver up to ~20% more usable oxygen while reducing over-breathing; habitual mouth breathing is linked to snoring, sleep apnea, metabolic issues, and reduced performance.

Breathe less and more slowly to improve efficiency and calm.
Most people chronically over-breathe; patterns like ~6 seconds in, 6 seconds out can lower blood pressure, improve gas exchange, and calm the nervous system by maintaining beneficial CO₂ levels instead of constantly blowing them off.

Train CO₂ tolerance instead of chasing more oxygen.
The urge to breathe is driven mainly by rising CO₂, not falling oxygen; through controlled breath holds and slower breathing, you can raise your CO₂ tolerance, which supports better endurance, calmer responses to stress, and reduced asthma and panic symptoms.

Treat mouth breathing and sleep-disordered breathing as core health issues, not side details.
Snoring and sleep apnea are strongly tied to mouth breathing, small airways, and tongue position; interventions like nasal surgery when needed, mouth taping, and airway-focused orthodontics can markedly improve sleep quality, blood pressure, and overall health.

Recognize that modern diets and orthodontics have literally shrunk our mouths and airways.
Soft, processed foods reduced chewing stress, leading to smaller jaws, crowded teeth, and narrower airways compared with ancient skulls; conventional extraction-and-retraction orthodontics can further shrink the mouth, while expansion-focused approaches can widen the palate and improve breathing.

Use targeted breathwork sessions to ‘stress and reset’ the nervous system.
Intense cyclical techniques like Wim Hof breathing or Kriya deliberately spike sympathetic activity, then allow a deep rebound into parasympathetic calm, which many people report helps with anxiety, autoimmune symptoms, and overall resilience when practiced regularly and safely.

Continuously monitor and correct unconscious breathing habits during daily tasks.
Phenomena like “email apnea” (holding or shallow breathing while on screens) are common and degrade oxygenation and focus; setting reminders or using pacing apps to maintain slow nasal breathing can counteract this and improve day-to-day mental clarity.

Notable Quotes
“Breathing has to be considered along with diet and exercise as a pillar of health.”
— James Nestor
“We have 50 years of rock solid science showing the problems with mouth breathing… and no one’s really been paying attention.”
— James Nestor

All right, we're rolling. Uh, first of all, I really enjoyed your book. It was really excellent. I got deep into it. I listened to the audiobook and it's in your voice, so this will be weird, sitting in. It's always weird when you meet somebody for the first time and, you know, you've heard their book and you hear them talking for, like, long periods of time, and then they're right there. But, uh, I really enjoyed it, man.
I guess I can't change the, uh, tone of my voice, then?
No, don't do that.
You're used to it? Okay.
Just keep it-
I'll keep it steady.
... keep it the way it is. Keep it, keep it real. (laughs) Um, what, what made you wanna write this? Like, wh- where did this come from?
It was actually two things. Uh, about 10 years ago, 11 years ago, I had this really weird experience. I was in San Francisco. There's a lot of breath work, yoga stuff going on there. And I kept getting pneumonia. I surf a lot at, at Ocean Beach-
Mmm.
... and I thought that that was the reason. So I kept getting bronchitis, pneumonia. Year after year, it just kept happening. So a doctor friend of mine suggested a breathing class might help. I didn't know much about this, but went down, signed up, and was sitting in the corner of this studio, cold room, legs crossed, breathing in this rhythmic pattern. Nothing crazy, just (breathing rapidly) and then really slow. And I sweated through my T-shirt, through my socks. My hair was sopping wet. Sweat all over my face. So I went back to her and I said, "What happened?" Like, "You're a doctor, you should know this." And she said, "Oh, you must have had a fever," or, "The room must have been too hot." So she had no idea. But I didn't know what to do with that story, so I just kind of filed it away, forgot about it for a number of years until I met some free divers. These are people who have, through the power of will, enabled themselves to hold their breath for six, seven, eight minutes at a time, and dive to depths far below what any scientist thought possible. So I thought, wow, there's something in breathing here that I don't know about and I figured other people might not know about as well.
Ah, that's r- that's, that's really interesting. You know, um, I've known a bunch of free divers, and, uh, I've known a, a bunch of, uh, jujitsu people that got really into yoga, primarily because of Rickson Gracie. Rickson Gracie, do you know who he is?
Mm-hmm. Oh, yeah.
Yeah. Famous, uh, probably the most famous of the gr- of the l- like, the classic jujitsu people. He's known as being the very best. He was, like, one of the, uh, original, real pioneers of jujitsu in America as well. And there's this, uh, documentary on him called Choke. Have you seen it?
