Circadian rhythms are important in determining the sleeping and feeding patterns of all animals, including human beings. There are clear patterns of core body temperature, brain wave activity, hormone production, cell regeneration and other biological activities linked to this daily cycle. In addition, photoperiodism, the physiological reaction of organisms to the length of day or night, is vital to both plants and animals, and the circadian system plays a role in the measurement and interpretation of day length.
example of these rhythms in both humans and animals is the circadian rhythms which occur every once a day.
Circadian rhythms regulate the sleep-wake cycle, hormone secretion, and body temperature, which in turn affect cognitive function, mood, and physical performance. Disruption of circadian rhythms can lead to sleep disorders, mood disturbances, and impaired cognitive abilities. These rhythms are driven by an internal biological clock located in the brain that responds to light and darkness cues from the environment.
Circadian rhythms govern daily variations in biological and psychological processes, such as sleep-wake cycles, hormone levels, and mood patterns. These rhythms are influenced by internal biological clocks as well as external cues like light and temperature. disruptions to circadian rhythms can impact overall health and well-being.
Depression has been demonstrated to interfere with Circadian rhythms. This means the brain is doing the wrong things at the wrong time. Further, lack of sleep from the night before can compound matters.

circadian rhythms.
Not exactly. Circadian rhythms are a subset of diurnal rhythms. Diurnal rhythms reoccur daily and can be circadian and non-circadian. Circadian rhythms can be set by the environment (entrainment), but are not dependent on environment stimulus for continuation (free-running) (ie. hormone secretion). Non-circadian rhythms are responsive to the environment, but still operate on a daily cycle (ie. the process of photosynthesis).
Circadian rhythms
circadian
True. Diurnal rhythms refer to biological processes that follow a 24-hour cycle, while circadian rhythms specifically refer to the body's internal clock that regulates these processes over a 24-hour period. Therefore, diurnal rhythms are a component of circadian rhythms.

yes
Circadian rhythms are a living organisms day/night cycles, daylight interacting with body hormone chemistry.
Melatonin
Circadian rhythms are regulated by the suprachiasmatic nucleus (SCN) in the brain, located in the hypothalamus. The SCN receives input from light-sensitive cells in the retina, helping to synchronize internal body clocks with the external environment.
