In human beings, circadian rhythms have been genetically organized to coordinate with night and day. A “biological master clock” that is centrally placed within the suprachiasmatic nucleus (SCN) within the hypothalamus ensures that daily human functions are controlled. This system works to generate biological night and biological day in order to control the physiological, as well as behavioral patterns suited for day and night. It controls night activities like rest, memory control, cellular restoration, and also brain development.
