Journal ArticleDOI
Stability, Precision, and Near-24-Hour Period of the Human Circadian Pacemaker
Charles A. Czeisler,Jeanne F. Duffy,Theresa L. Shanahan,Emery N. Brown,Jude F. Mitchell,D. W. Rimmer,Joseph M. Ronda,Edward J. Silva,James S. Allan,Jonathan S. Emens,Derk-Jan Dijk,Richard E. Kronauer +11 more
TL;DR: In this article, the intrinsic period of the human circadian pacemaker averages 24.18 hours in both age groups, with a tight distribution consistent with other species, with important implications for understanding the pathophysiology of disrupted sleep in older people.
Journal ArticleDOI
Bright light induction of strong (type 0) resetting of the human circadian pacemaker.
Charles A. Czeisler,Richard E. Kronauer,James S. Allan,Jeanne F. Duffy,Megan E. Jewett,Emery N. Brown,Joseph M. Ronda +6 more
TL;DR: The data indicate that the sensitivity of the human circadian pacemaker to light is far greater than previously recognized and have important implications for the therapeutic use of light in the management of disorders of circadian regulation.
Journal ArticleDOI
Evening use of light-emitting eReaders negatively affects sleep, circadian timing, and next-morning alertness
Anne Marie Chang,Anne Marie Chang,Daniel Aeschbach,Daniel Aeschbach,Daniel Aeschbach,Jeanne F. Duffy,Jeanne F. Duffy,Charles A. Czeisler,Charles A. Czeisler +8 more
TL;DR: It is found that the use of portable light-emitting devices immediately before bedtime has biological effects that may perpetuate sleep deficiency and disrupt circadian rhythms, both of which can have adverse impacts on performance, health, and safety.
Journal ArticleDOI
Adverse Metabolic Consequences in Humans of Prolonged Sleep Restriction Combined with Circadian Disruption
Orfeu M. Buxton,Sean W. Cain,Shawn P. O'Connor,James H. Porter,Jeanne F. Duffy,Wei Wang,Charles A. Czeisler,Steven Shea +7 more
TL;DR: In humans, prolonged sleep restriction with concurrent circadian disruption alters metabolism and could increase the risk of obesity and diabetes, and a cautionary message for employers to guard against causing adverse metabolic effects in workers by their shift scheduling practices is carried.
Journal ArticleDOI
Circadian and sleep/wake dependent aspects of subjective alertness and cognitive performance.
TL;DR: It was revealed that prior wakefulness within a range of 0–18 h significantly reduced alertness and performance and that the circadian rhythm of core body temperature paralleled the circadian Rhythm of alerts and performance.
