title: [Sleep is rhythm (and the rhythm, rhythm is)].
abstract: In this paper several aspects of the sleep-wake cycle, considered as a circadian rhythm, are reviewed. The principal characteristics of the circadian system (including its origin, entrainment and clinical applications) are described, as well as chronobiological sleep disorders, including advance or delay phase syndromes and desynchronization due to transmeridian flights or shiftwork.
