Treatment of Human Circadian Rhythm Sleep Disorders
In humans, external factors that are likely to affect on the biological rhythm (time cues) include the following: (1) the time on a clock, (2) light—dark cycle, (3) social interaction, (4) timing of dietary intake, and (5) sleep—wake schedule. Although the light—dark cycle is thought to be the strongest time cue in plants and animals, social interaction is believed to be the most potent time cue in humans (Aschoff, 1965). However, recent studies have revealed that light also exerts a strong influence on the human circadian rhythm (Lewy et al., 1980; Czeisler et al., 1986).
