Episode 5: A.L.A.N.: The Invisible Poison in Your Home

Artificial light at night may be the most overlooked metabolic toxin in modern life. In Part 1 of this two-part series, Dr. Alan Bradford explains how melatonin and cortisol are meant to work in opposition, how darkness triggers melatonin through the suprachiasmatic nucleus, and how light as low as 8 lux begins to shut that process down. You'll learn what melatonin actually does inside your cells, including its role in mitochondrial signaling and SIRT3 antioxidant defense, and why it behaves differently in cancer cells. Dr. Bradford also separates blue light fact from fiction, explains what modern LEDs are missing, and gives practical steps to protect your evenings. Next week, Part 2.
