Circadian rhythm disorders are problems with your circadian rhythm, the "internal body clock" that keeps your biological processes in step. This cycle lasts about 24 hours. The term circadian comes from Latin words that mean “around the day.” Patterns of brain waves, hormone production, cell regrowth, and other activities are linked to this cycle.
