Most of us are exposed to an abundance of artificial blue light on a daily basis, via our modern technology (lamps, cellphones, computers, TVs, etc). Our bodies physiologically respond to light from the blue portion of the spectrum with a state of wakefulness, via the suppression of melatonin production. This constant stream of artificial blue light is wreaking havoc on our circadian rhythms.
Today’s guest, a physicist, is one of the leading experts on this topic — Dr. Edward Carome. In this episode, you’ll learn how blue light interacts with our bodies by suppressing melatonin-production and some surprising, and not often discussed, effects this can have on us. Dr Carome relays some excellent strategies on how to minimize blue light exposure, particularly in the evening hours. Whether you are using these blue-light-producing modern devices on a daily basis or not, the information in this interview is extremely important! Enjoy, and please share your thoughts in the ReWild Yourself! Facebook group! I’d love to hear what strategies you are utilizing to safeguard your circadian rhythm!

Meet Dr. Carome
Dr. Carome is a retired professor of physics at John Carroll University. During his long and distinguished career, he has consulted widely with industry and governmental agencies, and has published widely in various technical journals. He has been awarded 21 U.S. patents. For more than two decades, he has conducted leading-edge research on fiber optics. His research has attracted more than $1.5 million in federal funding from such agencies as NASA, the FBI, the National Institutes of Health, the Office of Naval Research and the Army Office of Research, among others. The State of Ohio and such leading corporations as British Petroleum, Goodyear Aerospace and Litton Industries have added an additional $1 million or more in support for his research. He holds a doctorate in physics from Case Institute of Technology.
