The Light Revolution: How LED Lights Are Changing Our Health with Dr. Martine Moore-Ede

Mr. Biz Radio

Dr. Martin Moore-Ede, a former professor at Harvard Medical School, is a renowned expert in the field of circadian rhythms and their disruption by modern LED lighting. With a storied career spanning over 40 years, Dr. Moore-Ede has made significant scientific contributions, including leading the team that located the supra-chaismatic nucleus (SCN) — the biological clock in the human brain. As the founder and CEO of the consulting firm Circadian, he has developed technologies to assist those working unconventional hours. He is also the author of "The Light Doctor," a groundbreaking book addressing the health impacts caused by today's LED lights. n this enlightening episode of Mr. Biz Radio, host Ken Wentworth, known as Mr. Biz, engages with Dr. Martin Moore-Ede to explore the vital link between our well-being and the artificial light that surrounds us. The discussion focuses on how LED lights, although celebrated for their energy efficiency, are disrupting our natural circadian rhythms, leading to serious health consequences. Key Takeaways: - Circadian rhythms are disrupted by LED lights due to their blue-rich spectrum, which can lead to increased risks of cancer, obesity, diabetes, and heart disease. - Our eyes have special cells sensitive to blue light; exposure to this light at night sends incorrect signals to our brain's circadian clock. - To maintain healthy circadian rhythms: spend time outdoors in natural light, especially in the morning, and reduce exposure to blue light at least three hours before bedtime. - Use zero-blue or low-blue lights in the evening, and ensure sleeping environments are pitch dark to promote the natural production of the hormone melatonin. - Upcoming technologies like TVs and smart devices with adjusted blue light emissions could help mitigate the negative health impacts of blue-rich LED lighting.
