Video: ❶ Sleep And Biological Rhythms
All living things have their own biorhythms, depending on the main ones, since everyone has to adapt to light and temperature changes and to other features of the surrounding world. And it is the predictability of these cycles that allows them all to survive. And man is no exception. Location: Location:
The human body has its own biorhythms of very different lengths from milliseconds to ten years. Thanks to them, the body itself measures the time - this is the so-called "biological clock", which is closely related to the alternation of sleep and wakefulness. If biorhythms are disturbed for any reason, “breakdowns” appear in this internal clock and sleep problems begin.
The biological clock is controlled by light and darkness. Under normal conditions, a person completely obeys an approximately 25-hour (circadian) rhythm. Under the influence of this rhythm in the body, mechanisms are triggered that regulate the release of hormones, which cause activity or, on the contrary, the desire to sleep. The speed of psychomotor reactions, mental processes, performance and much more depend on them.
A healthy sleep is very important. When a person suffers from insomnia, all biorhythms go astray, as a result of which the body is not ready for an active life during the day, and at night it begins to show this activity.
Each person has their own characteristics (temporary) of the circadian regime. In different people, the duration of this rhythm ranges from 20 to 28 hours. These individual characteristics of the internal clock directly affect the change in sleep and wakefulness of a particular person. Therefore, it is enough for someone to sleep 5-6 hours, and for someone even 10 hours may not be enough.
In conclusion, I would like to say that a person himself knows which regime suits him best, based on the needs of his body.
