The light we see is as crucial as the food we eat, the water we drink, and the air we breathe. Former Harvard Medical School professor and 40-year leading expert in circadian clocks and human health, Dr. Moore-Ede speaks on why our health hinges on getting the right sort of light at the right time.
In this episode, he reveals the dangers of modern LED lighting, which often emits bright but unhealthy "junk light." Just as junk food wreaks havoc on our body, junk light disrupts our circadian rhythms, suppresses melatonin, and contributes to chronic diseases.
We cover:
* The Health Risks of LED Lighting: disrupts circadian rhythms, suppresses melatonin, and contributes to chronic diseases
* Junk Light and Lumens - how modern lighting regulations prioritise energy efficiency over human health
* Circadian Clocks and Longevity: light as essential for disease prevention and healing
* Rise of Myopia in Children: indoor living and reduced exposure to natural light are fueling skyrocketing rates of myopia
* Blue light blocking glasses - do you have the right sort?
* Practical Solutions for Healthier Lighting: simple changes you can make in your home and your life
