Detailed explanation-1: -Circadian rhythm is the 24-hour internal clock in our brain that regulates cycles of alertness and sleepiness by responding to light changes in our environment. Our physiology and behavior are shaped by the Earth’s rotation around its axis.

Detailed explanation-2: -Listen to pronunciation. (sir-KAY-dee-un RIH-thum) The natural cycle of physical, mental, and behavior changes that the body goes through in a 24-hour cycle. Circadian rhythms are mostly affected by light and darkness and are controlled by a small area in the middle of the brain.

Detailed explanation-3: -The circadian clock has an internally driven 24-hour rhythm that tends to run longer than 24 hours but resets every day by the sun’s light/dark cycle. Taking melatonina supplements can also shift the timing of the body’s “clock.”

Detailed explanation-4: -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.
