Journal ArticleDOI
Human sleep: its duration and organization depend on its circadian phase
Charles A. Czeisler,Elliot D. Weitzman,Martin C. Moore-Ede,Janet C. Zimmerman,Richard S. Knauer +4 more
TL;DR: Two- to threefold variations in sleep length were observed in 12 subjects living on self-selected schedules in an environment free of time cues and the duration of polygraphically recorded sleep episodes was highly correlated with the circadian phase of the body temperature rhythm at bedtime.
Journal ArticleDOI
Delayed Sleep Phase Syndrome: A Chronobiological Disorder With Sleep-Onset Insomnia
Elliot D. Weitzman,Charles A. Czeisler,Richard M. Coleman,Arthur J. Spielman,Janet C. Zimmerman,William C. Dement,Gary S. Richardson,Charles P. Pollak +7 more
TL;DR: A new syndrome called "delayed sleep phase insomnia" is described, which is proposed to be a disorder of the circadian sleep-wake rhythm in which the "advance" portion of the phase response curve is small.
Journal ArticleDOI
Chronobiology of aging: Temperature, sleep-wake rhythms and entrainment
TL;DR: Studies were carried out on a group of six young and six older normal men who lived under conditions of temporal, but not social isolation, from three to eight weeks, demonstrating a reduction in the period and amplitude of the body temperature rhythms during free-running in the older group.
Journal ArticleDOI
Timing of REM sleep is coupled to the circadian rhythm of body temperature in man.
Charles A. Czeisler,Charles A. Czeisler,Janet C. Zimmerman,Joseph M. Ronda,Martin C. Moore-Ede,Elliot D. Weitzman +5 more
TL;DR: There is an endogenous circadian rhythm of REM sleep propensity which is closely coupled to the body temperature rhythm and is capable of free-running with a period different from both 24 hr and the average period of the sleep-wake cycle.
Journal ArticleDOI
Chronotherapy: resetting the circadian clocks of patients with delayed sleep phase insomnia.
Charles A. Czeisler,Charles A. Czeisler,Charles A. Czeisler,Gary S. Richardson,Gary S. Richardson,Richard M. Coleman,Richard M. Coleman,Janet C. Zimmerman,Martin C. Moore-Ede,William C. Dement,Elliot D. Weitzman +10 more
TL;DR: A brief drug-free rescheduling treatment for Delayed Sleep Phase insomnia, a syndrome characterized by sleep-onset insomnia with difficulty in morning awakening, which was designed to reset patients' biological clocks by the phase delay route.
