How to Enhance Your Immune System | Dr. Roger Seheult

My guest is Dr. Roger Seheult, M.D., a board-certified physician in internal medicine, pulmonary diseases, critical care, and sleep medicine at Loma Linda University. We discuss the powerful benefits of light therapy, including infrared light, red light, and sunlight, for improving mitochondrial function in all the body’s organs. We also explore ways to reduce the risk of influenza, colds, and other illnesses that affect the lungs, sinuses, and gut.Topics include the flu shot, whether handwashing truly prevents illness transmission, and treatments for long COVID and mold toxicity. We review the efficacy of N-acetylcysteine (NAC), the power of hydrotherapy for combating infections, and strategies for improving sleep and overall health. Additionally, we discuss air quality. This episode provides actionable, science-based tools for preventing and treating infectious illnesses.Read the full show notes for this episode at hubermanlab.com.SponsorsAG1: https://drinkag1.com/hubermanJoovv: https://joovv.com/hubermanEight Sleep: https://eightsleep.com/hubermanLMNT: https://drinklmnt.com/hubermanFunction: https://functionhealth.com/hubermanOur Place: https://fromourplace.com/hubermanTimestamps00:00:00 Dr. Roger Seheult00:02:16 Avoiding Sickness, Immune System, Tool: Pillars of Health, NEWSTART00:08:03 Sponsors: Joovv & Eight Sleep00:10:46 Sunlight, Mitochondria, Tool: Infrared Light & Melatonin00:19:09 Melatonin Antioxidant, Reactive Oxygen Species (ROS)/Free Radicals00:26:38 Infrared Light, Green Spaces, Health & Mortality00:31:35 Infrared Light, Mitochondrial Dysfunction, Disease00:38:46 Sunlight & Cancer Risk?, Tools: UV Light, Clothing & Sunlight Exposure00:41:01 Sponsors: AG1 & LMNT00:43:32 Sunlight, Incidence of Influenza or COVID00:48:41 Tools: Sunlight Exposure Duration, Winter Months00:55:18 Infrared Lamps?, Winter Sunlight Exposure; Obesity & Metabolic Dysfunction00:59:48 Cloudy Days; Sunlight, Primitive Therapy, Hospitals01:11:33 Sponsor: Function01:13:21 Artificial Lights, Hospitals & Light Therapy?, ICU Psychosis01:22:16 Sleep & Darkness, Tools: Eye Mask, Bathroom Navigation; Meals & Light01:28:27 Influenza, Flu Shots, Swiss Cheese Model; Flu Shot Risks?01:38:13 Masks?, Flu; Handwashing01:42:16 Sponsor: Our Place01:43:57 Water, Sodium; Innate Immune System, Fever & Hydrotherapy01:53:46 Fever, Heat Hydrotherapy, Interferon & Immune System01:58:25 Cold Hydrotherapy, Vasoconstriction & White Blood Cells02:09:56 N-Acetyl Cysteine (NAC), Glutathione, White Clots, Flu, Covid02:19:28 Tool: NAC Dose & Regimen; Mucous, Flu Symptoms02:25:25 Zinc Supplementation, Copper; Exogenous Interferon02:28:40 Eucalyptus Oil, Inhalation02:32:22 Air, Smoking, Vaping, Nicotine Gum02:36:49 Fresh Air, Forest Bathing, Tool: Go Outdoors02:40:09 Nature vs Inside Environments, Dark Days/Bright Nights Problem02:52:38 Long COVID, Mitochondrial Dysfunction, Intermittent Fasting, Sunlight03:00:43 Covid & Varied Severity, Smell Loss Recovery03:05:04 Mold Toxicity, Lungs, Germ vs Terrain Theory, Immunocompromised03:11:46 Trust, Spirituality, Community, Faith; Forgiveness03:19:46 Hospital Admission, Tool: Asking Questions03:25:42 Zero-Cost Support, YouTube, Spotify & Apple Follow & Reviews, Sponsors, YouTube Feedback, Protocols Book, Social Media, Neural Network NewsletterDisclaimer & Disclosures

The Huberman Lab podcast is hosted by Andrew Huberman, Ph.D., a neuroscientist and tenured professor in the department of neurobiology, and by courtesy, psychiatry and behavioral sciences at Stanford School of Medicine. The podcast discusses neuroscience and science-based tools, including how our brain and its connections with the organs of our body control our perceptions, our behaviors, and our health, as well as existing and emerging tools for measuring and changing how our nervous system works.
Huberman has made numerous significant contributions to the fields of brain development, brain function, and neural plasticity, which is the ability of our nervous system to rewire and learn new behaviors, skills, and cognitive functioning. He is a McKnight Foundation and Pew Foundation Fellow and was awarded the Cogan Award, given to the scientist making the most significant discoveries in the study of vision, in 2017.
Work from the Huberman Laboratory at Stanford School of Medicine has been published in top journals, including Nature, Science, and Cell, and has been featured in TIME, BBC, Scientific American, Discover, and other top media outlets.
In 2021, Dr. Huberman launched the Huberman Lab podcast. The podcast is frequently ranked in the top 10 of all podcasts globally and is often ranked #1 in the categories of Science, Education, and Health & Fitness.
