The US Department of Energy came out with a new study regarding recent studies that have raised concerns over the possible health implications of light at night (LAN). They mention how work space lighting for shift workers has been associated with an increased risk of stress-related coronary heart disease, and research of circadian rhythms suggests that their disruption can compromise the body’s defenses against cancer. Studies also suggest that optical radiation is the primary regulating stimulus to the circadian system, and that the circadian system is most sensitive to short- wavelength blue light.
