More than 15 years of scientific research show that exposure to blue-rich light in the evening and at night increases the risk for cardiovascular disease by as much as 40 percent for night shift workers.

Most energy efficient LEDs in the market today are rich in the blue wavelengths that at night trigger the metabolic processes involved in hypertension, atherosclerosis, and cardiovascular disease through:

1.) Disruption of the circadian system (phase shifting and circadian misalignment)
2.) Melatonin-suppression and phase shifting

Make Lighting Healthier

Artificial illumination can stop us sleeping and make us ill. We need fresh strategies and technologies, argues Karolina M. Zielinska-Dabkowska.

Groundbreaking Evidence Shows Light at Night Increases Risk of Obesity and Diabetes

While it might make sense to turn up the Kelvin settings during the day and down toward night, it's not always that simple. MARK HALPER discovers the virtues of spectral power and natural light at offices from coast to coast in the US.

This past summer, LED Magazine held their first one-day immersive Lighting for Health and Wellbeing Conference. The program was exciting, the speakers were passionate, and the field is burgeoning with opportunity. But if there was one phrase uttered more than any other on July 27, it was "It's complicated."

LED Magazine interviews Martin Moore-Ede, M.D, Ph.D at the Lighting for Health and Wellbeing Conference in Newport Beach. California.
