Dr. Jack Feldman: Breathing for Mental & Physical Health & Performance | Episode 54
This episode my guest is Dr. Jack Feldman, Distinguished Professor of Neurobiology at University of California, Los Angeles and a pioneering world expert in the science of respiration (breathing). We discuss how and why humans breathe the way we do, the function of the diaphragm and how it serves to increase oxygenation of the brain and body. We discuss how breathing influences mental state, fear, memory, reaction time, and more. And we discuss specific breathing protocols such as box-breathing, cyclic hyperventilation (similar to Wim Hof breathing), nasal versus mouth breathing, unilateral breathing, and how these each effect the brain and body. We discuss physiological sighs, peptides expressed by specific neurons controlling breathing, and magnesium compounds that can improve cognitive ability and how they work. This conversation serves as a sort of "Master Class" on the science of breathing and breathing related tools for health and performance.   Thank you to our sponsors: Thesis - https://takethesis.com/huberman  Athletic Greens - https://www.athleticgreens.com/huberman  Headspace - https://www.headspace.com/specialoffer    Our Breath Collective: https://www.ourbreathcollective.com/huberman    Dr. Jack Feldman Links: UCLA website - https://bioscience.ucla.edu/people/jack-feldman Wikipedia - https://en.wikipedia.org/wiki/Jack_L._Feldman Twitter - https://twitter.com/prebotzinger Instagram - https://www.instagram.com/jacklfeldman    Our Patreon page: https://www.patreon.com/andrewhuberman    Supplements from Thorne: https://www.thorne.com/u/huberman    Social: Instagram - https://www.instagram.com/hubermanlab  Twitter - https://twitter.com/hubermanlab  Facebook - https://www.facebook.com/hubermanlab  Website - https://hubermanlab.com  Newsletter - https://hubermanlab.com/neural-network    Timestamps: 00:00:00 Introducing Dr. Jack Feldman 00:03:05 Sponsors: Thesis, Athletic Greens, Headspace, Our Breath Collective 00:10:35 Why We Breathe  00:14:35 Neural Control of Breathing: “Pre-Botzinger Complex” 00:16:20 Nose vs Mouth Breathing 00:18:18 Skeletal vs. Smooth Muscles: Diaphragm, Intracostals & Airway Muscles 00:20:11 Two Breathing Oscillators: Pre-Botzinger Complex & Parafacial Nucleus 00:26:20 How We Breathe Is Special (Compared to Non-Mammals) 00:33:40 Stomach & Chest Movements During Breathing 00:36:23 Physiological Sighs, Alveoli Re-Filling, Bombesin 00:49:39 If We Don’t Sigh, Our Lung (& General) Health Suffers 01:00:42 Breathing, Brain States & Emotions  01:05:34 Meditating Mice, Eliminating Fear  01:11:00 Brain States, Amygdala, Locked-In Syndrome, Laughing 01:16:25 Facial Expressions 01:19:00 Locus Coeruleus & Alertness 01:29:40 Breath Holds, Apnea, Episodic Hypoxia, Hypercapnia 01:35:22 Stroke, Muscle Strength, TBI 01:38:08 Cyclic Hyperventilation 01:39:50 Hyperbaric Chambers 01:40:41 Nasal Breathing, Memory, Right vs. Left Nostril 01:44:50 Breathing Coordinates Everything: Reaction Time, Fear, etc. 01:57:13 Dr. Feldman’s Breathwork Protocols, Post-Lunch  02:02:05 Deliberately Variable Breathwork: The Feldman Protocol 02:06:29 Magnesium Threonate & Cognition & Memory  02:18:27 Gratitude for Dr. Feldman’s Highly Impactful Work 02:20:53 Zero-Cost Support, Sponsors, Patreon, Instagram, Twitter, Thorne Please note that The Huberman Lab Podcast is distinct from Dr. Huberman's teaching and research roles at Stanford University School of Medicine.
