Circadian scientist Dr. Martin Moore-Ede reveals why the LED bulbs in nearly every home may be driving a rise in breast and prostate cancer, why he calls the light we now live under the tobacco of our time, and why the modern fear of the sun may be shortening our lives instead of protecting them!

Dr. Moore-Ede discovered the master circadian clock in the human brain, the suprachiasmatic nucleus, and ran a sleep and circadian research lab at Harvard Medical School for two decades. He has spent 50 years studying how light governs human health, and now argues that the shift to blue-rich LED lighting has created an environment our bodies were never built for.

He explains:

◼️ Why breast, prostate, and colorectal cancer track almost exactly with how much electric light a society uses

◼️ Why melatonin is not the sleep hormone you think it is, and what it really does at 2am

◼️ How LEDs strip out the red and infrared your mitochondria need for energy

◼️ Why the sun exposure data flips skin cancer advice on its head

◼️ Why your children are going short-sighted, and the wavelength that prevents it

◼️ Why the $200 blue-light glasses most people buy block the wrong blue
