This episode I describe how the organs of the body influence the function and health of our brain and how our brain controls our bodily organs. The conscious awareness of this brain-body dialogue is called interoception. I describe how two factors- mechanical forces (e.g., pressure, pain, volume, etc.) and chemical factors (e.g., gut acidity, microbiome diversity, etc.) combine to influence our moods, control inflammation, immune system, recovery from injury and more. I explain how specific actions of our lungs, heart, spleen, and diaphragm, control our brain via the vagus nerve and other neural pathways. I describe 11 science-supported protocols for enhancing brain-body health and the logic behind them.\nAccess the full show notes for this episode at hubermanlab.com.\nThank you to our sponsors\nAG1 (Athletic Greens): https://athleticgreens.com/huberman\nLMNT: https://drinklmnt.com/huberman\nSupplements from Momentous\nhttps://www.livemomentous.com/huberman\nTimestamps\n(00:00:00) Your Sense of Self: Interoception\n(00:01:25) Protocol 1: Fermented Foods, Not Fiber, to Reduce Inflammation\xa0\n(00:03:45) Sponsors: AG1, LMNT\n(00:08:22) Main Drivers of Feelings & Performance\n(00:11:45) Brain-Body: A Mechanical & Chemical Dialogue\xa0\n(00:17:50) LDB (Lung-Diaphragm-Brain) Dialogue\xa0\xa0\n(00:21:00) Protocols 2, 3, 4: Control Heart Rate With Breathing\n(00:29:08) Sensing Lung Pressure: Piezo Receptors\n(00:30:54) Carbon Dioxide, From Air to Blood\n(00:34:02) Protocol 5: Alert While Calm\n(00:40:50) Baroreceptors: Hering-Breuer Reflex\n(00:42:47) Gut Volume & The Desire to Open Your Mouth\xa0\n(00:48:18) Protocol 6: Enhancing Gut-To-Brain Communication, Fasting\xa0\n(00:51:50) Intestines, Fatty Acids, Amino Acids & Sugar\n(00:57:00) Protocol 7: Reducing Sugar Cravings with Specific Amino Acid Nutrients\xa0\n(00:58:58) Gut Acidity (Is Good)\n(01:02:20) Improving Nasal Microbiome\xa0\n(01:04:13) Inflammation & Microbiome: Fiber vs. Fermented\xa0\n(01:11:15) Protocol 8: Reducing Inflammation & Enhancing Brain Function w/Fermented Foods\n(01:13:10) Leaking Guts, Auto-Immune function & Glutamine\n(01:15:50) Gut Acidity: HCl (hydrochloric acid), Pepsin\n(01:18:30) Probiotics & Brain Fog\n(01:21:45) Nausea: Happens in Your Brain; Area Postrema\n(01:28:25) Protocol 9: Reducing Nausea: Ginger, Peppermint, CBD, etc.\n(01:30:40) Fever: Triggers and Control Knobs: OVLT\n(01:37:00) Protocol 10: Cooling the Blood Properly\n(01:38:53) Sensing Feelings, Vagus Nerve, Stress\n(01:41:50) Mental Emotions Reflect Bodily Conditions\n(01:45:00) Sensing Other People\u2019s Emotions via the Body\n(01:46:00) Protocol 11: Increasing Interoception, Sensing Heartbeat\xa0\n(01:50:40) Conclusions & Resources\nDisclaimer
