Daily rhythms of human in many behavioral, physiological, biochemical and cognitive functions are generated by endogenous oscillators that function as internal 24-hour clocks. Under natural condition, these rhythms are synchronized to the daily environmental cycles such as light and darkness. In constant conditions, these rhythms free-run with unique period of the individuals. It has been revealed that the center of these daily rhythms is suprachiasmatic nucleus(SCN) located in hypothalamus. Sleep-activity rhythm is the most distinctive one, and most of the proteins used in a daily activity are synthesized during the period of REM sleep. Many types of memory also show daily function. Educational implications of these were discussed.
