BACKGROUND INFORMATION Modern electric lighting enables people to work, sleep, eat, and receive services throughout the 24-hour day. As a result, many individuals encounter new patterns and types of electrical light, change the timing of their meals, and experience sleep disturbances and other stresses. Those factors can disrupt circadian rhythms and possibly lead to adverse...

Mol Psychiatry. 2013 Jul;18(7):751-7. doi: 10.1038/mp.2013.70. Epub 2013 May 28. Abstract Humans and other organisms have adapted to a consistent and predictable 24-h solar cycle, but over the past ~130 years the widespread adoption of electric light has transformed our environment. Instead of aligning behavioral and physiological processes to the natural solar cycle, individuals respond to...

5 July 2019 The results of the recent IARC Monographs evaluation of the carcinogenicity of night shift work have now been published in The Lancet Oncology. This summary article presents the conclusions of the IARC Monographs Meeting 124. Shift work involving circadian disruption was previously evaluated by the IARC Monographs, in 2007. In this updated evaluation, the Working Group chose the...
