NTP Review of Shift Work at Night, Light at Night, and Circadian Disruption

May 2, 2021,
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...
