WCircadian rhythm
  • A circadian rhythm /sɜrˈkeɪdiən/ is any biological process that displays an endogenous, entrainable oscillation of about 24 hours.
  • The term circadian comes from the Latin circa, meaning "around" (or "approximately"), and diēs, meaning "day". The formal study of biological temporal rhythms, such as daily, tidal, weekly, seasonal, and annual rhythms, is called chronobiology.
  • Although circadian rhythms are endogenous ("built-in", self-sustained), they are adjusted (entrained) to the local environment by external cues called zeitgebers (from German, "time giver"), which include light, temperature and redox cycles.
