  • How Red Light Powers Your Mitochondria & Why LEDs Harm Your Health | Dr. Glen Jeffery
    Jun 29 2026

    In this episode, my guest is Dr. Glen Jeffery, PhD, a professor of neuroscience at University College London's Institute of Ophthalmology and a leading expert on how light interacts with mitochondria to shape health and aging.

    Today, he discusses how red and near-infrared light penetrate deep into the body and improve mitochondrial function and overall health. We also discuss how detrimental modern indoor life has become and why expensive red light panels are likely unnecessary and possibly harmful.

    By the end, you'll understand sunlight as a biological input your body evolved to depend on and the low-cost, practical steps you can take to get more of it.

  • Light as a Nutrient: Sunlight, Circadian Rhythm & Metabolic Health | Dr. Max Gulhane
    Jun 8 2026

    Dr. Max Gulhane (MD) is a practising family medicine physician and health-optimising physician with a passion for root-cause analysis of human chronic disease and longevity. We discuss the full solar spectrum and how ultraviolet, visible, blue, red and near-infrared light each affect human physiology, including the POMC pathway, nitric oxide and blood pressure, and the evidence on sunlight, skin cancer and the vitamin D paradox. We discuss how artificial light at night suppresses melatonin and disrupts the circadian control of DNA repair, cardiovascular health, and metabolism. For those interested in light and circadian health, Dr. Gulhane offers a grounded, mechanism-focused framework for aligning daily light exposure with human biology.

  • Transform Your Health by Optimizing Mitochondria, Bioelectricity, and Alkalinity | John Galamaga
    Aug 8 2024

    In this episode, my guest is John Galamaga, a licensed massage therapist and certified personal trainer from the Cooper Institute in Dallas. He’s also a Senior Master Instructor in LAMAS QiGong, and a foremost expert in the field of health and wellness with over 40 years of experience. Today we discuss how to leverage movement, nutrition, and other lifestyle factors to enhance your overall health.

    John draws from his extensive experience to share personal stories and setbacks that led him to profound insights. After a health scare during a workout and unsatisfactory answers from his cardiologist, John, 20 years old at the time, sought alternative solutions with an open mind. His journey revealed that the traditional medical approach might not be the best path to a healthier lifestyle.

    Building on this, we explore why high-intensity training might not be the optimal route to better health and its effects on mitochondrial function. We then discuss science backed practices that enhance mitochondrial health, which have yet to emerge in the mainstream fitness world.

    We also discuss proper stretching techniques, the idea of a “one diet fits all” approach, ancient practices of Qigong and sungazing, electromagnetic therapy, and he challenges common misconceptions within the health space. We close the discussion with actionable steps and key takeaways to help you kickstart and further your health journey.
