Removing Blue from LED Light at Night May Reduce Obesity and Diabetes Risk

Dr. Martin Moore-Ede will be presenting new research at the "Lighting for Health and Wellbeing" Conference in a presentation titled "Taking the Obesity and Diabetes Risk out of Light at Night" inNewport Beach, CA on July 27, 2017.

The harmful effects of conventional LED lights at night, which disrupt circadian clocks and increase appetite, insulin resistance and diabetes risk, may be avoided by removing bio-active blue wavelengths from white LED light, according to a research study titled "Taking the Obesity and Diabetes Risk out of Light at Night" to be presented by Dr. Martin Moore-Ede, CEO of Circadian Light at the "Light for Health and Wellbeing" Conference in Newport Beach, CA on July 27, 2017. 

Dr. Moore-Ede, the former Harvard Medical School professor who led the team that located the suprachiasmatic nucleus (SCN) circadian clock in the human brain, will present the results of cross-over pilot studies comparing insulin resistance and appetite levels in healthy volunteers working simulated 12-hour night shifts under conventional LED lights, or under Circadian Light LED fixtures which maintain high quality white light while regulating the dosage and timing of the bio-active blue content across the 24 hour day-night cycle by time of day, location and season.

"The preliminary results show that blue-depleted LED light at night minimizes circadian disruption and also appears to prevent the elevated appetite and insulin resistance seen in the same subjects exposed to conventional LED lights at night," said Dr. Moore-Ede. "The Circadian LED lights remove over 90% of the 430-500 nm harmful blue content at night while producing quality white light with a color temperature (CCT) above 3200K, and a color rendering index (CRI) above 80". "For the first time, we do not have to choose between energy efficient LED lights and health, we can have both!" concluded Dr. Moore-Ede.

The Light for Health and Wellbeing Conference will bring together leading researchers from Harvard, Stanford, and Rensselaer Polytechnic Institute's Center for Lighting Enabled Systems & Applications (LESA) with lighting industry innovators to discuss the latest science on how light influences human health. The conference will be held on July 27, 2017 at the Newport Beach Marriott Hotel & Spa, Newport Beach, California. Dr. Moore-Ede's presentation is at 9:30 am.
