Detailed explanation-1: -Circadian rhythms are physical, mental, and behavioral changes that follow a 24-hour cycle. These natural processes respond primarily to light and dark and affect most living things, including animals, plants, and microbes. Chronobiology is the study of circadian rhythms.

Detailed explanation-2: -Each type of biological rhythm has a certain name to show how long it lasts: Diurnal (night and day) Circadian (24 hours) Ultradian (less than 24 hours)

Detailed explanation-3: -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-4: -There are four biological rhythms: circadian rhythms: the 24-hour cycle that includes physiological and behavioral rhythms like sleeping. diurnal rhythms: the circadian rhythm synced with day and night. ultradian rhythms: biological rhythms with a shorter period and higher frequency than circadian rhythms.

Detailed explanation-5: -Circadian: A term derived from the Latin phrase “circa diem, ” meaning “about a day”; refers to biological variations or rhythms with a cycle of approximately 24 hours.
