Chronobiologists know that virtually all physiological processes and behavioural characteristics follow the circadian rhythm. Amongst them are the sleep cycle, mood, body temperature, and the production of vital hormones.
Sleeplessness may have a variety of causes, but some are quite clearly the consequence of a circadian rhythm disorder. People often suffer from lack of concentration and impaired daytime performance, daytime sleepiness (napping), negative effects on social life, and irritability. |
