Detailed explanation-1: -In conclusion, regardless of the mechanism our results suggest that when people shorten their sleep by going to bed later they significantly phase delay their circadian rhythms, or that when they go to bed earlier they phase advance their circadian rhythms.

Detailed explanation-2: -For this reason, circadian rhythms are closely connected to day and night. While other cues, like exercise, social activity, and temperature, can affect the master clock, light is the most powerful influence on circadian rhythms.

Detailed explanation-3: -The light/dark cycle of the sun has a powerful effect on the circadian clock, sleep, and alertness. Your body’s circadian clock responds to light, as a signal to be awake, and dark, as a signal to fall asleep. Increase your amount of light during the day to be more alert.
