Light can have a significant impact on your sleep and your health. In today's podcast, you're going to discover the hidden dangers of light-emitting diode (LED) lighting that most people are completely unaware of, including the risk of cataracts, blindness, age-related macular degeneration, mitochondrial dysfunction, metabolic disorders, disrupted circadian biology and sleep, cancer and more. LED light is currently used in applications as diverse as aviation lighting, automotive headlamps, advertising, general lighting, traffic signals, camera flashes, and lighted wallpaper. Large-area LED displays are used as stadium displays, dynamic decorative displays, and dynamic message signs on freeways. Thin, lightweight message displays are used at airports and railway stations, and as destination displays for trains, buses, trams, and ferries. LED's are also used in traffic lights and signals, exit signs, emergency vehicle lighting, ships' navigation lights, aircraft cockpits, brake lights, submarine and ship bridges, astronomy observatories, night vision, glowsticks and more. My guest is Dr. Alexander Wunsch, who is a physician, researcher and lecturer in light medicine and photobiology with particular interest in light effects and beneficial or adverse health impacts of solar radiation and artificial light sources on endocrine and cellular levels in humans. He conducts studies on photobiological effects of optical (UV, VIS and IR) radiation. In his private medical practice in Heidelberg, he uses therapeutic light spectra in combination with other biophysically based treatments and develops light equipment for medical and cosmetic purposes. He is associate lecturer at the Wismar University of Applied Sciences and mentors students in their master theses in light and health-associated topics. Alexander Wunsch presents at international conferences and operates as a consultant for federal authorities, media and industry.
