Episode 377 | The Sunlight Solution with William F. Supple Jr., PhD We welcome back Dr. Bill Supple, who makes the case that our modern fear of sunlight has contributed to widespread vitamin D deficiency and chronic disease. His new book, The Sunlight Solution: Reclaiming Vitamin D, Reversing the Chronic Disease Epidemic, and Making America Healthy Again, challenges the modern caution against sun exposure and invites readers to reconsider the role of sunlight as natural, life-giving medicine. We discuss vitamin D as more than a bone-health nutrient--including its role in immune regulation, inflammation, cardiovascular health, brain health, aging, and resilience. We also look at benefits of sunlight beyond vitamin D, including circadian rhythm support, sleep, mood, and other light-driven biological effects. Dr. Supple also walks us through the history of heliotherapy, whether sunscreen is “the new margarine,” the debate regarding sunlight and melanoma, and practical questions about testing serum 25-hydroxyvitamin D, supplementation, and seasonal strategies for places like Washington State.
