Timing of light exposure affects mood and brain circuits

January 19, 2019
Abstract Transl Psychiatry. 2017 Jan; 7(1): e1017. Published online 2017 Jan 31. doi: 10.1038/tp.2016.262 Temporal organization of physiology is critical for human health. In the past, humans experienced predictable periods of daily light and dark driven by the solar day, which allowed for entrainment of intrinsic circadian rhythms to the environmental light–dark cycles. Since the adoption...
