Abstract
Multiple physiological and biological rhythms known as «circadian» are generated by the biological clock that controls them within the suprachiasmatic nuclei of the hypothalamus. However, the most emblematic circadian rhythm is that of sleep and awakening. It is therefore crucial to check how the clock may be involved in chronic insomnia. What is the influence of the clock on the time and quality of sleep? What are the typical clock disorders that explain insomnia in adolescents, shift and night workers, the elderly and the blind individuals? What are the tools to recommend in general and specialized medicine in the evaluation of the clock in insomnia? What influence finally of the light on the clock and the light therapy to recommend? So many questions and elements of understanding often-poorly known of chronic insomnia.
