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...

APRIL 21, 2021 by University of Waterloo https://medicalxpress.com/news/2021-04-shift-work-negative-impacts-health-affects.html Shift-work and irregular work schedules can cause several health-related issues and affect our defense against infection, according to new research from the University of Waterloo. These health-related issues occur because the body’s natural clock, called the circadian clock, can be disrupted by inconsistent changes in the sleep-wake schedule...
