If some phenomenon in our lives happens all the time with a given frequency, we just don’t pay attention to him. The most popular example — if you go on the train for a long period of time, then the rhythmic clatter of the wheels just not noticed, and we think that we drive in absolute silence. And if we take not the train ride, and a few larger period of time, say, several millennia? All inhabit our planet, the organisms that live in strictly defined rhythms, formed over thousands of years. Flowering plants, seasonal bird migration, photosynthesis, metabolism, and more is done strictly cyclically, rhythmically, the base of which is the cycle of “light-shadow” associated with the rotation of the earth around its axis and the rotational period of the Sun around its axis, averaging 27 days.
Biological rhythms are periodic changes in the activity of biological systems. Among them are a hierarchy. The short — vysokochastotnye biorhythms, lasting from a fraction of a second to ½ hour. These oscillation periods is subject to the activity of the brain, the muscles (including the heart), rhythm of external respiration.
For follow high-frequency mid-frequency rhythms, or as they are called circadian (daily), lasting for up to 28 hours (sometimes up to 60 hours), at the same time allocate a special period of about 90 minutes (it can clearly be seen, in particular, when the change of activity the rest of the newborns). Another example of a mid-range rhythms — the alternation of the different sleep stages (fast and slow sleep) and fluctuations in performance during the day. It is the most studied class of biorhythms, which are subject to (at least, from the established to the present time) more than 300 physiological processes in the body. For example, the heart rate reaches its peak to 15-16 hours, the value of systolic blood pressure from 15 to 18 hours, the breathing frequency at 13-16 hours, the number of red blood cells — in the afternoon. By the way, a well-known gradation of people into “owls” and “larks” is from the same source, from daily biorhythms.
The longest biorhythms are low frequency, which can be monthly (lunar cycle) and annual.
Practical importance of biological rhythms in medicine
As you might guess, the medicine was unable to stay away from scientific progress and willingly used and uses the knowledge of the biorhythms of the human body.
So, a popular non-pharmacological method for the treatment of sleep disorders consists of the following: a person completely isolated from sources of information about the real time of day, and gradually “move” the time bedtime until until it’s closer to normal.
As I said, indicators of the respiration rate maximum between 13 and 16 hours. So, therapeutic interventions in bronchial asthma recommend, when these indicators are in the lowest part of the diurnal cycle, which is determined individually for each person by round-the-clock monitoring with registering physiological parameters.
Diuretic drugs will have the greatest effect if they take in 10 hours. Peak hypoglycemic action of insulin observed in the interval from 8 to 13 hours. Do you know why allergies lurk, usually in the evening? Because at this time (or rather in 21-24 hours) the maximum concentration of histamine — the main mediator of allergic reactions — basophils and mast cells granules.
What is desenhos
To synchronize their activity with the geophysical daily cycles, we use the number of physical and social factors. First is the alternation of darkness and light, bound to our activity during the day. Social factors is the daily routine of labor, so to speak, everyday life and daily routine: trips to work, eating, watching football on the evening, dying away street rumble.
Failure of circadian rhythm — desenhos — refers to a pathological condition. With the circadian rhythm linked to the many physiological processes in our body, and any deviation from the usual way of life is able to make chaos in this multi-component system. Desenhos is fraught with digestive disorders, sleep disorders, loss of appetite, lethargy and apathy in the daytime, when, it would seem that the activity should be the maximum. Desengrase the danger is that, even with the apparent coming to the normal phases of diurnal rhythm and disappearance of the above symptoms, he may go into a latent form, and make chronic. The individual physiological processes is still fragmented and not rebuilt, what allows us to speak about the normal functioning of the body. There may be neuroses, persistent disorders of digestion and of sleep.
Desingers notes when you move to another time zone, changing work shift, it is often found in pilots flying over long distances. To exit from this state must be carefully and meticulously observe the daily routines. For example, food: there should be about 5 times a day according to individual energy costs, not to eat at night.
Knowledge of biological rhythms — an effective tool for the physician in the diagnosis and treatment of diseases. But “mere mortals” also worth to listen to your body and to fulfill all his requirements: it will help to avoid many problems in the future.
