Circadian rhythm

Circadian rhythms are oscillatory (periodic) processes in human cells and organs that are observed daily as a result of the influence of external natural factors on the hypothalamus. When sunlight enters the eyes at a certain time, the hormone cortisol is released

Circadian and circadian rhythms are close, but not identical concepts. Circadian rhythm is a narrower concept that refers to a measure of the duration of physiology, which is determined by the duration of two “bio-clocks” (periods of alternation between sleep and wakefulness). The circadian division of biological time is broader. Includes not only physiological, but also behavioral, social and psychological rhythms. An example of the latter is a person’s biological or biographical clock (sleep, doing favorite things, getting ready for bed).

Circadian rhythm is a process that affects many aspects of our body, including hormone levels, metabolism and activity. It is associated with biological rhythms that are regulated by changes in temperature, lighting and other environmental factors.

Circadian rhythm (circadian rhythm) is a cyclical process that occurs in our body and affects our life rhythm and mood. Our body reacts to the change of day and night, which causes changes in the functioning of many organs and systems. This cycle is associated with hormones that regulate our sleep, appetite, body temperature and other body functions.

Circadian rhythms play an important role in regulating our health and well-being. For example, lack of sleep can lead to poor mood, decreased immunity, and an increased risk of developing diseases. Lack
