Circadian rhythms are entrained by light: dark cycles, meaning that they follow a 24-hour cycle based on exposure to light and darkness. They also allow homeostatic set points to be changed appropriately for the overall physiological circumstance, such as being awake or asleep. Both of these functions are important for maintaining a healthy sleep-wake cycle and avoiding disruptions such as jet lag.
