The Deep Science Of Blue Light Toxicity, & Why LED Trashes Your Health with Dr. Alexander Wunsch #278

Dr. Alexander Wunsch is one of the world’s foremost experts on everything light. If you’ve been listening to the show for a while, you know how passionate I am about biohacking my environment, and light is a big part of that, and it was a dream of mine to have Dr. Wunsch on the show to help me clear some things up. Because there is a lot of conflicting information out there about whether you should avoid sunlight and the risks of living indoors, where we’re bombarded with artificial light. So, Dr. Wunsch is here to clear up any misconceptions and teach us what we need to know to optimize our health and the health of our families. This information is also particularly pertinent to maintaining your physical, mental, and spiritual wellness during this period of time when people all around the world are spending more time at home than usual, exposing themselves to even less natural light and even more toxic light. After listening to this episode, you will understand why our light environment is just as important as our air, food, and water — and you are going to look at your blue-blocking glasses (or the people you have made fun of for wearing blue-blocking glasses) in a whole new light. 06:00 — What is photobiology? Photobiology is the science of light acting on biological organisms Its critical role in human healing and health Our circadian rhythm: how to manage it and why it matters Sunlight played a paramount role in the development of life, starting 3.5 billion years ago “Junk light”   10:45 — The different types of lighting we are exposed to & how they affect us The color spectrum of daylight Vs. the color spectrum from artificial lights Why incandescent bulbs weren’t as bad as LED or fluorescent lights How blue light exposure wrecks our eyes, brains, and sleep Why short wavelengths of light have the greatest effect on our cellular metabolism The more ultraviolet radiation in the environment, the more stress put on your cells Why it matters that your skin is also susceptible to blue light Why blue-blocking glasses are critical at night As soon as the body detects more blue light in its environment, it starts producing more stress hormones — and this is perfect in nature but horribly damaging in our artificial environments full of blue light Were blue lights put into school and work environments to increase productivity? And did they know about the harmful effects?   20:37 — Did offices, schools, factories, hospitals, and big-box stores adopt artificial blue lights knowing about their harmful effects? Or did they just want to save money? “Light sells” The role of light in our industrial and economic history, going back to the first Industrial Revolution Trading short-term productivity for long-term harm It’s hard to tell just how damaging our artificial environments are because we don’t have any good control groups anymore The parallel development of light bulbs and electricity   35:40 — The legislation that made selling incandescent bulbs illegal (to save energy) & the legislation that was passed to make it legal again Did we actually need to ban incandescent bulbs for the environment? Were they...
