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...

Distinct circadian mechanisms govern cardiac rhythms and susceptibility to arrhythmia

May 2, 2021
Hayter, E.A., Wehrens, S.M.T., Van Dongen, H.P.A. et al. Distinct circadian mechanisms govern cardiac rhythms and susceptibility to arrhythmia. Nat Commun 12, 2472 (2021). https://doi.org/10.1038/s41467-021-22788-8 Abstract Electrical activity in the heart exhibits 24-hour rhythmicity, and potentially fatal arrhythmias are more likely to occur at specific times of day. Here, we demonstrate that circadian clocks within the brain and heart set...
