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.[2] History[edit] The first recorded observation of an endogenous circadian oscillation was by the French scientist Jean-Jacques d'Ortous de Mairan in 1729. The term circadian was coined by Franz Halberg in the 1950s.[14] Criteria[edit] To be called circadian, a biological rhythm must meet these three general criteria:[15] Origin[edit] Circadian rhythms allow organisms to anticipate and prepare for precise and regular environmental changes.
