Rhythm of life

All living organisms, from the simplest unicellular and ending with man, have biological rhythms, which are manifested in periodic changes in the nature of life and, as the most accurate clock, measure the life time of each of us.

No process in the human body can not occur continuously, and should alternate with the opposite direction of action.

Every breath mixed with breath, working with rest, wakefulness with sleep, synthesis with cleavage etc. Thus, the condition of the human body is never constant, and all of his physiological and energetic parameters subject to continuous fluctuations about their average values, as frequency and amplitude. These oscillations are called biorhythms.

No process in the human body can not occur continuously, and should alternate with the opposite direction of action.

With the help of biorhythms all living organisms, including humans, ensure the stability of their non-equilibrium thermodynamic state.

Biorhythms are a way of successful existence of all living organisms. They allow the human body to adapt to all cyclical changes in the environment.

Biological rhythms have regular changes in their intensity. The ability to change the life is inherited. Biorhythms are observed in all cells, tissues and organs, in whole organisms and in populations. However, the human body can not exist without the environment. And since the external environment itself, all spheres of the universe are also covered by vibrational rhythmic movements, it is not surprising that one of the essential properties of all living things is the rhythm of processes.

It is established that the human biological rhythms are closely related to the modifying factor of the environment. This relationship is the basis of the unity of the organism with the environment and largely determines the environmental laws.

Most diseases occur in humans due to the rhythm of the functioning of organs and systems of the body.

In the course of historical development of man and all other living beings inhabiting our planet, learned a certain rhythm of life, due to the rhythmic changes in the geophysical parameters of the environment, the dynamics of metabolic processes.

In a certain rhythm fluctuate indicators of the nervous, muscular, cardiovascular, respiratory and digestive systems, as well as endocrine and hematological. In this rhythm, the content and activity of dozens of substances in various tissues and organs of the body, in blood, urine, sweat, saliva, the intensity of metabolic processes, energy and plastic support of cells, tissues and organs change.

All these rhythms (and a person has already found more than a hundred) are connected with each other in a certain way, forming a single, coordinated in time rhythmic system of the body.

To visualize this information, consider the average duration of some rhythmic processes in the human body.

The rhythmic system of the body reflects the interconnected course of rhythms of different functions, which gives doctors and physiologists valuable material for the diagnosis of diseases and forecasting the human condition. For example, body weight of each person reaches the maximum values in 18-19 hours, the body temperature of 16-18 hours, the heart rate in 15-16 hours, and the breathing frequency in 13-16 hours, histological arterial pressure in 15-18 hours. The level of red blood cells in the blood – in 11-12 hours, leukocytes-in 21-23 hours, hormones in plasma – in 10-12 hours, insulin-in 18 hours, total blood protein-in 17-19 hours. In humans, depending on the time of day, the physiological state, intellectual capabilities and even mood change cyclically. Scientists have proved that the cyclic system of the body is controlled by the brain through cyclic fluctuations in the concentration of hormones in the blood.

Disturbance of sleep and wakefulness rhythm can lead not only to insomnia, but also to a disorder of the cardiovascular, respiratory and digestive systems. Therefore, it is so important to observe the regime of the day.

Observance of biorhythms is one of the ways to keep your health.

Changing rhythms-going beyond the norm or their appearance where they were not previously detected-is associated with the disease. Aging is the gradual loss of rhythms. Lack of biorhythms is incompatible with life.

In recent years, much has been done in the science of biorhythms to establish the mechanism of hormonal rhythms. Scientists have discovered in the human brain “circadian center”, and in it – the so-called” clock genes ” biological rhythms of our health.

During the day, our body is “awake” and is mainly set to process the accumulated nutrients to get energy for an active day life.

On the contrary, at night, nutrients accumulate and are distributed throughout the body, in accordance with the instructions of the brain, there is a recovery and “repair” of worn tissues. Changes in the intensity of metabolism are regulated by the endocrine system, i.e. hormones.

In the evening, before nightfall, in the blood from the upper cerebral appendage, the epiphysis, released “sleep hormone” – melatonin. This amazing substance is produced by the epiphysis only in the dark time of day, and the time of its presence in the blood is directly proportional to the duration of the night. In some cases, insomnia in the elderly is associated with insufficient secretion of melatonin by the epiphysis. That is why melatonin preparations are often used as sleeping pills.

Melatonin causes a decrease in body temperature, in addition, it regulates the duration and change of sleep phases.

Human sleep is an alternation of slow-wave and paradoxical phases.

Slow-wave sleep is characterized by low-frequency activity of the cerebral cortex. This is “sleep without hind legs”, a time when the brain is completely resting. During paradoxical sleep, the frequency of fluctuations in the electrical activity of the brain increases, and we see dreams. This phase is close to wakefulness and serves as a springboard to awakening. Slow-wave and paradoxical phases are replaced by one another 4-5 times per night, in time with changes in melatonin concentration in our body.

The onset of night is accompanied by other hormonal changes: the production of growth hormone increases and the production of adrenocorticotropic hormone (ACTH) by another brain appendage – the pituitary gland decreases.

Growth hormone stimulates anabolic processes, such as cell reproduction and the accumulation of nutrients (glycogen) in the liver. No wonder they say: “Children grow up in a dream.”

ACTH causes the release into the blood of adrenaline and other “stress hormones” (glucocorticoids) from the adrenal cortex, so reducing its level allows you to remove the day’s excitement and peacefully fall asleep. In the moment of falling asleep from the pituitary gland highlighted opioid hormones, having narcotic effect, the endorphins and enkephalins. Thanks to them, the process of immersion in sleep is accompanied by pleasant sensations.

Before awakening, a healthy body prepares for active wakefulness, at this time the adrenal cortex begins to produce hormones that excite the nervous system – glucocorticoids. The most active of them – cortisol, which leads to increased pressure, increased heart rate, increased vascular tone and reduced blood clotting. That is why clinical statistics indicate that acute heart attacks and intracerebral hemorrhagic strokes occur mainly in the early morning. Currently, scientists are developing drugs that reduce blood pressure,which can reach the peak concentration in the blood only in the morning, preventing the possibility of patients with deadly attacks.

Why do some people get up “neither light nor dawn”, while others do not mind to sleep until noon? It turns out that the well-known phenomenon of “owls and larks” is quite a scientific explanation which is based on the works of Jami, Seizer of the Research center for sleep (Sleep Research Center) at Stanford University in California. She found that the minimum concentration of cortisol in the blood usually falls in the middle of a night’s sleep, and its peak is reached before awakening.

In “larks” maximum cortisol release occurs earlier than most people – at 4-5 o’clock in the morning.

Therefore, “larks” are more active in the morning, but get tired faster in the evening. They begin to sleep early, as melatonin enters the bloodstream well before midnight.

In “owls” the situation is reversed: melatonin is released later, closer to midnight, and the peak of cortisol release is shifted by 7-8 hours in the morning. These time frames are purely individual and can vary depending on the severity of the morning (“larks”) or evening (“owls”) chronotypes.

From the biorhythms of the organism, we move on to the rhythms of human brain activity, which control the functioning of the physical body and consciousness in full accordance with the resonance effect of electromagnetic waves that propagate around the Earth in the Earth – ionosphere cavity.
