My biological clock tells me what. Biological clock (biorhythms) of a person, circadian rhythm of the body

What you need to know about the human biological clock?

Hello! Today, we, the Valitov brothers, welcoming our visitors to our blog, will tell on this page about the human biological clock.

Since they were originally laid in us by nature itself even before our birth. These watches determine the algorithm of behavior, lifestyle and general condition of a person.

Their course depends on the season, external natural factors, the change of day or night, directly determining the ability of people to survive in this world.

What is this biological clock? What life rhythms are subject to the strict patterns of the schedule of these hours, and how they make the human body subconsciously obey them every day.

What organs in our body are responsible for the regulation of these cyclic processes, and how do people need to adjust their biological clock in order to live in harmony with the outside world. You can find out about this by reading our article.

Stay with us!

Features of the internal clock

The biological clock is a special internal system of biorhythms of the human body.

It determines its vital activity by directly linking external natural factors with processes:

nutrition;
Growth;
Reproduction;
Restoration of forces;
Active physical or mental activity.

Usually this system is not connected with the traditional Earth day, but works on the principle of cyclicity with various time repetitions from second, monthly or seasonal to annual.

Their totality determines the rhythm of all life processes of people, causing the normal functioning of all their systems with the work of internal organs.

Here, each organism maintains its own individual time schedule, which can be influenced by both natural factors in the form of exposure to the sun, moon, wind, or rain, as well as social factors due to the daily routine.

At the same time, depending on the daily chronotype, all people are divided into:

"Larks" with the main performance in the morning or the first half of the day.
"Owls", which are inherent in the evening peak of wakefulness or physical activity.
"Doves" with mixed-day activity.

The work of our biorhythms is regulated by the brain, which produces certain hormones for this, such as:

Melatonin, which provides people with "night" unconscious life support;
Creatine, responsible for mental and physical performance;
Serotonin, which increases people's sense of joy, happiness, psycho-emotional positive component.

How does the internal clock work?

Numerous studies of the human body show that all the processes occurring in it are determined by the state of the rhythm of daily changes in its biological structure.

These rhythms obey the strict laws of nature, determining the daily routine of people's lives and their state of health. Therefore, we will consider the schedule and characteristics of their main stages.

From 22 to 5 am

Initially, in this period of the biological schedule, the human body is in a state of physical exhaustion, gradually recovering until 5 am for the next day.

Wherein:

The body rests, allowing the liver to calmly process all the beneficial substances, removing poisons or toxins from the body;
Restores performance at the cellular level.
The brain sums up the day, rejecting the unnecessary, allowing people to fully sleep, going through all the cyclic phases of sleep;
In the peak period of this stage, people's blood pressure drops, heart rate and pulse decrease, breathing and blood circulation slow down.

It is here that we will pause our story, inserting a small remark, for people who are busy with their main work at night.

Are you a long distance driver? Obviously, this happens very often. Therefore, you, like no one else, should be very careful on the track from midnight to three o'clock.

Since at this time, no matter how much you would like, your body becomes lethargic due to the night hormone melatonin, the body becomes sensitive to cold, and the brain slows down the speed of reaction to optical stimuli.

So take our advice! Try to park your car at the nearest parking lot during this peak time, stop and rest for a while. This will benefit and save you from an emergency on the track.

5 to 8

This time from the biological schedule is characterized by a period of awakening.

After alternating phases of light and deep sleep, a person begins to:

Acute hearing;
Increased heart rate and blood pressure;
Increase immune defense.

By 8 am, his body had completely rested, restoring its strength.

9 to 14

This period in the biological schedule is due to an increase in working capacity and the level of mental activity.

Here the heart works rhythmically, the threshold of pain sensitivity decreases, and physical or mental stress is practically not felt.

Up to 12 days is the time of greatest efficiency. After it, people feel tired and the first decline in activity, which is necessary for rest, followed by a lunch break from 13 to 14.

From 14 to 22

The afternoon schedule of biological time cycles is characterized by some instability with peaks and troughs in activity. First, after dinner, a person's working capacity increases. Here he again enters his working form.

The time before 17 is the most productive for athletes with active physical activities in the fresh air.

By 18 o'clock, people's mental alertness gradually begins to decrease. By 19, cerebral blood flow decreases, so a person may feel a headache due to a slight decrease in the activity of biorhythms.

At the same time, the time from 20 to 21 is very productive for actors and students, when they memorize texts very well.

And drivers at this time acquire an excellent form and quick response to external stimuli.

By 10 p.m., the activity of our biological rhythms decreases, the body temperature drops, the body prepares for sleep.

How the biological clock is set

The correct functioning of the biological clock is affected not only by the age indicators of people, but also by sharp fluctuations in weather conditions, such as:

magnetic storms;
Atmospheric pressure jumps;
Humidity;
wind or temperature.

At the same time, older people are much more difficult to tolerate these factors. Therefore, to reduce the influence of these external loads, they need to be dealt with:

Therapeutic exercise;
swimming;
Hardening of your body;
Organization of proper nutrition and night rest.

In addition, it is advisable for these people to include teas from “daytime” chronobiotics, such as green tea, eleutherococcus or coffee tree, in the morning diet for these people. As "night" chronobiotics, it is advisable to use decoctions from:

Oregano;
Mint;
Hops;
Valerian.

Good luck to everyone, goodbye and meet again!

The biological clock of a person or biorhythms is the internal system of a living organism that determines the cycle of its life. Botanists are sure that plants also live according to their biological clock, which “tells” when to swell buds, fold or bloom petals, turn green or dry leaves, and so on. All human organs function according to the biological clock, and this mechanism starts automatically, regardless of external factors. And it takes a long time for the body to rebuild.

Biological clock of the body in the morning

The internal biological clock of a person is arranged in such a way that every hour of the day in its own way affects people physically and mentally. For example, no one feels as cheerful in the evening as in the morning. For the rhythm of the biological clock, it does not matter whether you are a "lark" or an "owl".

4 hours. Our body receives a dose of the stress hormone cortisone, as if during sleep it “drained its batteries”, and this portion is necessary for us to become efficient when we wake up. However, this "injection" of activity is fraught with some diseases. The risk of a heart attack is especially high in the early morning hours. Patients with asthma also feel it - at this hour the bronchi are dangerously narrowed.

5 o'clock. The concentration of cortisone produced by the adrenal cortex is six times higher than the daytime. Medicines act differently at certain hours, so doctors, taking into account the chronobiology of the body, natural hormone secretions, prescribe large doses of medicine in the early hours of the day. The standard "three times a day" formula is outdated.

6 hours. Cortisone on the human body due to the biological clock at this time acts as an internal alarm clock. The general metabolism starts to move. The level of sugar and amino acids in the blood rises. Thus, the energy necessary for the working day is prepared.

7 o'clock. At this time, the biological clock works to wake up. After the morning shower, breakfast follows. The forgotten “eat breakfast” rule is back in vogue. Nutrition experts note that a person should get at least 2,000 kilocalories at breakfast in order to lose weight. And the same portion in the evening leads to obesity. The key to this phenomenon lies in the chronology of the digestive organs, when before lunch they convert carbohydrates into energy, and in the evening - into fats.

8 ocloc'k. The glands produce a large number of hormones. Most people are on their way to work. But they have not yet plunged entirely into everyday worries. It is interesting from a medical point of view that those suffering from rheumatism especially feel aching in the bones, because the feeling of pain in the morning is exacerbated to the limit. The bad news for smokers, too: morning cigarettes constrict blood vessels to a greater extent.

9 o'clock. For those who are scheduled for injections, it is best to go to the treatment room to avoid fever and swelling. Organs in this biological clock are highly resistant to X-ray exposure. Experiments on rats showed that animals exposed to high doses of radiation at this time lived more than 120 days. Those who received the same dose, but at nine o'clock in the evening, died within 13 hours.

10 hours. Body temperature has reached its maximum, as well as the performance associated with it. Short-term memory functions especially well (while long-term memory is stimulated by the afternoon hours). A text read at about 9 o'clock, for example, is better remembered than one read at 3 o'clock. However, it is quickly erased from memory after a week, which cannot be said about the text read in the afternoon. Chinese scientists believe that during this biological clock, the body is charged with a large amount of energy. Shaking hands before dinner looks more energetic than later.

11 o'clock. Before lunch, we are exceptionally efficient, especially in the account. For schoolchildren, math looks easy between 9 and 12 am and 4.30 and 6 pm. All internal organs at this biological hour, including the heart, are in excellent shape, and if research is carried out at this time, then some heart diseases will go unnoticed. At the same time, it becomes so sensitive that in stressful situations before lunch, the heart rate quickens to a greater extent than in the evening.

What does the biological clock say during the day?

12 hours. There is a continuous increase in the acid content in the stomach. After morning activity, in accordance with the biological rhythm at this hour, a person has a need for rest. Those who do not adhere to this rule are in danger. According to statistics, those who can afford an afternoon nap are 30% less likely to have a heart attack compared to those who continue to work. The need for sleep is caused by a weakening of the blood supply to the brain. The stomach needs blood to support the digestion of food.

13 hours. Efficiency compared to the average per day is reduced by 20%. The liver produces a lot of bile.

14 hours. Blood pressure and hormone levels drop. Fatigue is especially noticeable. A ten-minute rest is enough to overcome the fatigue phase. Given the biological clock of the body, drivers are advised to take a nap for a few minutes instead of strong tea or coffee at this time. In painful medical procedures, local anesthesia lasts longer and is easier to bear. New knowledge refutes the opinion that it is better to start the operation in the morning. The same applies to dental manipulations: at 14 o'clock our teeth are insensitive to pain. Medical anesthesia lasts half an hour. In the evening, its effect decreases to 19 minutes, and before dinner it lasts only 12 minutes. The same study found that medications had the least effect on toothache at night.

15 hours. The desire to work arises with renewed vigor, regardless of whether you rested or not. The second peak of performance begins.

16 hours. Blood pressure and circulation increase. At this time, the human biological clock works efficiently, for example, runners achieve excellent results. The training effect is especially great, while in the morning it is less. Medications that increase acidity are effective.

17 hours. There is an increase in vitality, breathing, as they say, with a full chest. "At full speed" work the kidneys and bladder. Between 4 and 6 pm, hair and nails grow fastest.

The work of the biological clock in the evening and at night

18 hours. In the evening, the pancreas is active. The liver is tolerant of alcohol.

19 hours. The internal biological clock at this time of day lowers blood pressure and pulse to such an extent that doctors warn of the dangers of taking blood pressure lowering drugs. And drugs that affect the central nervous system have an increased effect.

20 hours. The content of fats in the liver decreases, the blood in the veins pulsates rapidly. Even the lowest doses of antibiotics have a strengthening effect on the body (until 4 am). The most optimal time for taking antibiotics is 20 hours 32 minutes!

21 o'clock Keeping in mind the schedule of a person's biological clock, you should not fill your stomach with food, especially fatty food, at this time. It will remain undigested until the next morning.

22 hours. The performance drops sharply. The number of leukocytes in the blood increases - more than 12 thousand white blood cells per 1 mm, while in the morning their number is about 5 thousand. Medicines should not be used to avoid side effects. From now on, not a single cigarette must be smoked until morning! It is very difficult for the body to cleanse itself of the poisons of nicotine at night.

23 hours. The metabolism is reduced to a minimum. And with it, blood pressure, pulse rate and body temperature go down. Cortisone production stops. For this reason, twice as many children are born at night as during the day.

24 hours. Skin regenerates faster at night because cells divide faster than during the day.

1 am. Plunging into deep sleep, the human biological clock still works (we spend six years in hibernation during our lives).

2 hours. Drivers behind the wheel react slowly to optical stimuli. The number of accidents is rising sharply. Most people get feverish. The body is extremely sensitive to cold.

3 hours. The state of mind reaches its lowest point. It is supported by the hormone melatonin, which makes people sleepy and lethargic. (Daylight depresses the production of melatonin, so during the day we are active, in a good mood.) At this hour, the suicide curve increases: depressed people often wake up at this time, their mood deteriorates sharply, under the influence of gloomy thoughts. The liver decomposes alcohol taken in the evening.

It has long been noted that all life on Earth obeys certain rhythms, which are set by global processes. This is the daily rotation of the planet around its axis and its movement in a circumsolar orbit. Living organisms somehow feel the time, and their behavior is subject to its flow. This is manifested in the alternation of periods of activity and sleep in animals, in the opening and closing of flowers in plants. Migratory birds return to their nesting grounds every spring, hatch chicks and migrate to warmer climes for the winter.

What is a biological clock?

The rhythmic flow of all life processes is a property inherent in all the inhabitants of our planet. For example, marine unicellular flagellates glow at night. It is unknown why they do this. But during the day they do not glow. Flagellates received this property in the process of evolution.

Every living organism on Earth - both plants and animals - has an internal clock. They determine the frequency of life, tied to the duration of the earth's day. This biological clock adjusts its course to the frequency of the change of day and night, they do not depend on temperature changes. In addition to daily cycles, there are seasonal (annual) and lunar periods.

The biological clock is to some extent a conditional concept, implying the ability of living organisms to navigate in time. This property is inherent in them at the genetic level and is inherited.

Studying the mechanism of the biological clock

For a long time, the rhythm of the life processes of living organisms was explained by the rhythm of changes in environmental conditions: illumination, humidity, temperature, atmospheric pressure, and even the intensity of cosmic radiation. However, simple experiments have shown that the biological clock works regardless of changes in external conditions.

Today it is known that they are in every cell. In complex organisms, clocks form a complex hierarchical system. This is necessary for the functioning as a whole. If any organs and tissues are not coordinated in time, various types of diseases arise. The internal clock is endogenous, that is, it has an internal nature and is adjusted by signals from the outside. What else do we know?

The biological clock is inherited. In recent years, evidence of this fact has been found. Cells have clock genes. They are subject to mutation and natural selection. This is necessary to coordinate the processes of life with the daily rotation of the Earth. Since at different latitudes the ratio of the length of day and night during the year is not the same, clocks are also needed to adapt to the change of seasons. They must take into account whether day and night add or decrease. In another way it is impossible to distinguish between spring and autumn.

By studying the biological clock of plants, scientists have found out the mechanism of their adaptation to changes in the length of the day. This happens with the participation of special phytochrome regulators. How does this mechanism work? The phytochrome enzyme exists in two forms that change from one to the other depending on the time of day. This results in a clock controlled by external signals. All processes in plants - growth, flowering - depend on the concentration of the phytochrome enzyme.

The mechanism of the intracellular clock has not yet been fully understood, but most of the way has been covered.

Circadian rhythms in the human body

Periodic changes in the intensity of biological processes are associated with the alternation of day and night. These rhythms are called circadian, or circadian. Their frequency is about 24 hours. Although circadian rhythms are associated with processes occurring outside the body, they are endogenous in origin.

A person does not have organs and physiological functions that would not be subject to daily cycles. Today there are more than 300 of them.

The human biological clock regulates the following processes in accordance with daily rhythms:

Heart rate and breathing;

The body's consumption of oxygen;

Intestinal peristalsis;

The intensity of the work of the glands;

Alternating sleep and rest.

These are just the main manifestations.

The rhythmicity of physiological functions occurs at all levels - from changes within the cell to reactions at the level of the organism. Recent experiments have shown that circadian rhythms are based on endogenous, self-sustaining processes. The human biological clock is set to fluctuate every 24 hours. They are associated with changes in the environment. The course of the biological clock is synchronized with some of these changes. The most characteristic of them are the alternation of day and night and diurnal temperature fluctuations.

It is believed that in higher organisms the main clock is located in the brain in the suprachiasmatic nucleus of the thalamus. Nerve fibers from the optic nerve lead to it, and with the blood, among others, the hormone melatonin, produced by the pineal gland, is brought. This is an organ that was once the third eye of ancient reptiles and has retained the functions of regulating circadian rhythms.

Biological clock of organs

All physiological processes in the human body proceed with a certain cyclicity. Changes in temperature, pressure, blood sugar concentration.

Human organs are subject to the daily rhythm. Over the course of 24 hours, their functions alternately experience periods of ups and downs. That is, always, at the same time, for 2 hours, the body works especially efficiently, after which it goes into a relaxation phase. At this time, the body rests and recovers. This phase also lasts 2 hours.

For example, the phase of rising activity of the stomach falls on the period from 7 to 9 hours, followed by a decline from 9 to 11. The spleen and pancreas are active from 9 to 11, and rest from 11 to 13. In the heart, these periods fall at 11-13 hours and 13-15. In the bladder, the phase of activity is from 15 to 17, peace and rest - from 17 to 19.

The biological clock of organs is one of those mechanisms that allowed the inhabitants of the Earth to adapt to the daily rhythm over millions of years of evolution. But the civilization created by man is steadily destroying this rhythm. Studies show that it is easy to unbalance the body's biological clock. All it takes is a radical change in diet. For example, start eating in the middle of the night. Therefore, a rigid diet is a fundamental principle. It is especially important to observe it from early childhood, when the biological clock of the human body “winds up”. Life expectancy directly depends on this.

Chronogerontology

This is a new, recently emerged scientific discipline that studies age-related changes in biological rhythms that occur in the human body. Chronogerontology arose at the intersection of two sciences - chronobiology and gerontology.

One of the subjects of research is the mechanism of functioning of the so-called "large biological clock". This term was first introduced by the outstanding scientist V. M. Dilman.

“Large biological clock” is a rather arbitrary concept. Rather, it is a model of the aging processes occurring in the body. It gives an understanding of the relationship between a person's lifestyle, his food addictions and the actual biological age. This clock counts down the lifespan. They record the accumulation of changes in the human body from birth to death.

The course of the large biological clock is uneven. They either rush or lag behind. Many factors influence their course. They either shorten or lengthen life.

The principle of functioning of a large biological clock is that it does not measure time intervals. They measure the rhythm of processes, or rather, its loss with age.

Research in this direction can help in solving the main issue of medicine - the elimination of aging diseases, which today are the main obstacle in reaching the species limit of human life. Now this figure is estimated at 120 years.

Dream

The internal rhythms of the body regulate all life processes. The time of falling asleep and waking up, the duration of sleep - the “third eye” - the thalamus, is responsible for everything. It has been proven that this part of the brain is responsible for the production of melatonin, a hormone that regulates human biorhythms. Its level is subject to daily rhythms and is regulated by the illumination of the retina. With a change in the intensity of the light flux, the level of melatonin increases or decreases.

The mechanism of sleep is very delicate and vulnerable. Violation of the alternation of sleep and wakefulness, which is inherent in man by nature, causes serious harm to health. For example, long-term shift work that involves working at night is associated with a higher risk of diseases such as type 2 diabetes, heart attacks and cancer.

In a dream, a person completely relaxes. All organs rest, only the brain continues to work, systematizing the information received during the day.

Reduced sleep duration

Civilization makes its own adjustments to life. By examining the biological clock of sleep, scientists have found that a modern person sleeps 1.5 hours less than people in the 19th century. What is the danger of reducing the time of night rest?

Violation of the natural rhythm of alternating sleep and wakefulness leads to failures and disturbances in the functioning of the vital systems of the human body: immune, cardiovascular, endocrine. Lack of sleep leads to excess body weight, affects vision. A person begins to feel discomfort in the eyes, the clarity of the image is disturbed, and there is a danger of developing a serious disease - glaucoma.

Lack of sleep provokes malfunctions in the human endocrine system, thereby increasing the risk of a serious illness - diabetes mellitus.

The researchers found an interesting pattern: life expectancy is longer in people who sleep between 6.5 and 7.5 hours. Both reduction and increase in sleep time lead to a decrease in life expectancy.

Biological clock and women's health

Many studies have been devoted to this problem. The biological clock of a woman is the ability of her body to produce offspring. There is another term - fertility. It is about the age limit favorable for the birth of children.

A few decades ago, the clock showed a mark of thirty years. It was believed that the realization of oneself as mothers for the fair sex after this age was associated with a risk to the health of the woman and her unborn child.

Now the situation has changed. Significantly - 2.5 times - the number of women who conceived a child for the first time at the age of 30 to 39 increased, and those who did this after 40 increased by 50%.

Nevertheless, experts consider the age of 20-24 a favorable age for motherhood. Often the desire to get an education, to realize oneself in the professional field wins. Only a few women take responsibility for raising a baby at this age. Sexual maturity is 10 years ahead of emotional maturity. Therefore, most experts are inclined to believe that for a modern woman, the optimal time for the birth of a child is 35 years. Today they are no longer included in the so-called risk group.

Biological clock and medicine

The response of the human body to various influences depends on the phase of the circadian rhythm. Therefore, biological rhythms play an important role in medicine, especially in the diagnosis and treatment of many diseases. So, the effect of drugs depends on the phase of the circadian biorhythm. For example, in the treatment of teeth, the analgesic effect is maximally manifested from 12 to 18 hours.

Changing the sensitivity of the human body to drugs is studied by chronopharmacology. Based on information about daily biorhythms, the most effective drug regimens are being developed.

For example, purely individual fluctuations in blood pressure values require this factor to be taken into account when taking medications for the treatment of hypertension, ischemia. So, in order to avoid a crisis, people at risk should take medications in the evening, when the body is most vulnerable.

In addition to the fact that the biorhythms of the human body affect the effect of taking drugs, rhythm disturbances can be the cause of various diseases. They belong to the so-called dynamic ailments.

Desynchronosis and its prevention

Daylight is of great importance for human health. It is sunlight that provides natural synchronization of biorhythms. If the illumination is insufficient, as it happens in winter, a failure occurs. It can be the cause of many diseases. Mental (depressive states) and physical (decrease in general immunity, weakness, etc.) develop. The cause of these disorders lies in desynchronosis.

Desynchronosis occurs when the biological clock of the human body fails. The reasons may be different. Desynchronosis occurs when changing the time zone for a long period, during the period of adaptation during the transition to winter (summer) time, during shift work, alcohol addiction, disordered eating. This is expressed in sleep disorders, migraine attacks, decreased attention and concentration. As a result, apathy and depression may occur. Older people are more difficult to adapt, they need more time for this.

For the prevention of desynchronosis, the correction of body rhythms, substances are used that can affect the phases of biological rhythms. They are called chronobiotics. They are found in medicinal plants.

The biological clock lends itself well to correction with the help of music. It helps to increase productivity when performing monotonous work. With the help of music, sleep disorders and neuropsychiatric diseases are also treated.

Rhythm in everything is the way to improve the quality of life.

The practical significance of biorhythmology

The biological clock is an object of serious scientific research. Their customers are many sectors of the economy. The results of studying the biological rhythms of living organisms are successfully applied in practice.

Knowledge of the rhythms of life of domestic animals and cultivated plants helps to increase the efficiency of agricultural production. This knowledge is used by hunters and fishermen.

Daily fluctuations in the body of physiological processes are taken into account by medical science. The effectiveness of taking medications, surgical interventions, performing medical procedures and manipulations directly depends on the biological clock of organs and systems.

Achievements of biorhythmology have long been used in organizing the work and rest regime of airliner crews. Their work involves crossing several time zones in one flight. Elimination of the adverse effect of this factor is of great importance for maintaining the health of airline flight crews.

It is difficult to do without the achievements of biorhythmology in space medicine, especially when preparing for long-term flights. Far-reaching grandiose plans for the creation of human settlements on Mars, apparently, will not do without studying the features of the functioning of the human biological clock in the conditions of this planet.

Our biological clock

Every hour of the day affects people physically and mentally in its own way. For example, no one feels as cheerful in the evening as in the morning. And it doesn’t matter if you are a “lark” or an “owl”.

Let's start with four in the morning. Our body receives a dose of the stress hormone cortisone, as if during sleep it “drained its batteries”, and this portion is necessary for us to become efficient when we wake up. However, this "injection" of activity is fraught with some diseases. The risk of a heart attack is especially high in the early morning hours. Patients with asthma also feel it - at this hour the bronchi are dangerously narrowed.

5 o'clock. The concentration of cortisone produced by the adrenal cortex is six times higher than the daytime. Medicines act differently at certain hours, so doctors, taking into account the chronobiology of the body, natural hormone secretions, prescribe large doses of medicine in the early hours of the day. The standard "three times a day" formula is outdated.

6 hours. Cortisone acts as an internal alarm clock. The general metabolism starts to move. The level of sugar and amino acids in the blood rises. In this way, the energy necessary for the working day is prepared.

7 hours. After waking up and having a morning shower, breakfast follows. The forgotten “eat breakfast” rule is back in vogue. Nutrition experts note that a person should get at least 2,000 kilocalories at breakfast in order to lose weight. And the same portion in the evening leads to obesity. The key to this phenomenon lies in the chronology of the digestive organs, when before lunch they convert carbohydrates into energy, and in the evening - into fats.

8 ocloc'k. The glands produce a large number of hormones. Most people are on their way to work. But they have not yet plunged entirely into everyday worries. It is interesting from a medical point of view that those suffering from rheumatism especially feel aching in the bones, because the feeling of pain in the morning is exacerbated to the limit. The bad news for smokers, too: morning cigarettes constrict blood vessels to a greater extent.

9 o'clock. For those who are scheduled for injections, it is best to go to the treatment room to avoid fever and swelling. The body is highly resistant to X-ray exposure. Experiments on rats showed that animals exposed to high doses of radiation at this time lived more than 120 days. Those who received the same dose, but at nine o'clock in the evening, died within 13 hours.

10 hours. Body temperature has reached its maximum, as well as the performance associated with it. Short-term memory functions especially well (while long-term memory is stimulated by the afternoon hours). A text read at about 9 o'clock, for example, is better remembered than one read at 3 o'clock. However, it is quickly erased from memory after a week, which cannot be said about the text read in the afternoon. Chinese scientists believe that at this time our right limbs are charged with a large amount of energy. Shaking hands before dinner looks more energetic than later.

11 hours. Before lunch, we are exceptionally efficient, especially in the account. For schoolchildren, math looks easy between 9 and 12 am and 4.30 and 6 pm. The heart is also in excellent shape, and if research is done at this time, some heart diseases will go unnoticed. At the same time, it becomes so sensitive that in stressful situations before lunch, the heart rate quickens to a greater extent than in the evening.

12 hours. There is a continuous increase in the acid content in the stomach. After the morning activity, there is a need for rest. Those who do not adhere to this rule are in danger. According to statistics, those who can afford an afternoon nap are 30% less likely to have a heart attack compared to those who continue to work. The need for sleep is caused by a weakening of the blood supply to the brain. The stomach needs blood to support the digestion of food.

13 hours. Efficiency compared to the average per day is reduced by 20%. The liver produces a lot of bile.

14 hours. Blood pressure and hormone levels drop. Fatigue is especially noticeable. A ten-minute rest is enough to overcome the fatigue phase. Drivers are advised to take a nap for a few minutes instead of strong tea or coffee. In painful medical procedures, local anesthesia lasts longer and is easier to bear. New knowledge refutes the opinion that it is better to start the operation in the morning. The same applies to dental manipulations: at 14 o'clock our teeth are insensitive to pain. Medical anesthesia lasts half an hour. In the evening, its effect decreases to 19 minutes, and before dinner it lasts only 12 minutes. The same study found that medications had the least effect on toothache at night.

15 hours. The desire to work arises with renewed vigor, regardless of whether you rested or not. The second peak of performance begins.

16 hours. Blood pressure and circulation increase. At this time, runners achieve excellent results. The training effect is especially great, while in the morning it is less. Medications that increase acidity are effective.

17 hours. There is an increase in vitality, breathing, as they say, with a full chest. "At full speed" work the kidneys and bladder. Between 4 and 6 pm, hair and nails grow fastest.

18 hours. The pancreas is active. The liver is tolerant of alcohol.

19 hours. Blood pressure and pulse drop to such an extent that doctors warn of the dangers of taking blood pressure lowering drugs. And drugs that affect the central nervous system have an increased effect.

20 hours. The content of fats in the liver decreases, the blood in the veins pulsates rapidly. Even the lowest doses of antibiotics have a strengthening effect on the body (until 4 am). The most optimal time for taking antibiotics is 20 hours 32 minutes!

21 o'clock Do not fill your stomach with food, especially oily. It will remain undigested until the next morning.

22 hours. The performance drops sharply. The number of leukocytes in the blood increases - more than 12 thousand white blood cells per 1 mm, while in the morning their number is about 5 thousand. Medicines should not be used to avoid side effects. From now on, not a single cigarette must be smoked until morning! It is very difficult for the body to cleanse itself of the poisons of nicotine at night.

23 hours. The metabolism is reduced to a minimum. And with it, blood pressure, pulse rate and body temperature go down. Cortisone production stops. For this reason, twice as many children are born at night as during the day.

24 hours. Skin regenerates faster at night because cells divide faster than during the day.

1 hour of the night. A person falls into a deep sleep (we spend six years in our life in hibernation).

2 hours. Drivers behind the wheel react slowly to optical stimuli. The number of accidents is rising sharply. Most people get feverish. The body is extremely sensitive to cold.

3 hours. The state of mind reaches its lowest point. It is supported by the hormone melatonin, which makes people sleepy and lethargic. (Daylight depresses the production of melatonin, so during the day we are active, in a good mood.) At this hour, the suicide curve increases: depressed people often wake up at this time, their mood deteriorates sharply, under the influence of gloomy thoughts. The liver decomposes alcohol taken in the evening.

This is how the human body works at certain hours of the day. Knowing the algorithm of the behavior of your body, you can regulate your behavior. But if you still get sick, then do not rush to go to the doctor. Perhaps the color will help you.

The work of the internal organs of a person by the hour

Our ancestors knew that all people, animals and plants have the ability to sense time or, as they say now, felt their biological clock and lived in accordance with their biological rhythm. The change of seasons of the year, lunar cycles, day and night are directly related to these hours.
In the daytime, our body is dominated by metabolic processes aimed at extracting energy from the accumulated nutrients. At night, the energy reserve spent during the day is replenished, regeneration processes are activated, tissues are restored and internal organs are “repaired”.

WHY IS IT BETTER TO START YOUR DAY AT 6 AM?

or How to restore the biological clock of the DAY?

Heart, liver, lungs, kidneys - all organs live and work by the clock, each has its own peak of activity and recovery period. And if, for example, the stomach is forced to work at 21:00, when the “day regimen” is provided for rest, the acidity of gastric juice rises by a third above the norm, which leads to the development of gastrointestinal pathologies and exacerbation of peptic ulcers. Night load is also contraindicated for the heart: a failure in the daily activity of heart muscle cells is fraught with hypertrophy with the subsequent development of heart failure.

Schedule of the body by the hour from 4:00 to 22:00

04:00 - The adrenal cortex “wakes up” first: from 4 in the morning it begins to produce hormones that excite the nervous system. The most active, cortisol, increases the level of glucose in the blood, as well as blood pressure, which leads to vascular tone, increases the rhythm of the heartbeat - this is how the body prepares for the upcoming daily stress. There is an aggravation of hearing: the slightest noise - and we wake up. At this hour, peptic ulcer disease often reminds of itself, attacks occur in patients with asthma. The pressure during this period is low, the brain is poorly supplied with blood - this hour is also called fatal, sick people often die from 4 to 5 in the morning.
There is a division and the most active renewal of the largest number of cells. Cell growth hormones are actively produced. The skin is actively renewed.

In terms of energy: from 3 to 5 o'clock
the lung meridian begins to work actively. During the hours of its activity, energy and blood move from a state of calm to movement, begin to spread throughout the body. At this time, all organs of the human body must rest. Only in this way can the lungs rationally distribute energy and blood.

05:00 - We have already changed several phases of sleep: the phase of light sleep, dreaming and the phase of deep dreamless sleep. Rising at this time quickly comes to a cheerful state. The large intestine begins to work - the time comes for liberation from toxins and waste. The body begins to activate, pressure rises, the level of hormones in the blood rises, and defenses become activated.
06:00 - The pressure and temperature begin to rise, the pulse quickens. We are waking up. An increase in blood pressure (by 20-30 points), the risk of hypertensive crises, strokes, heart attacks. Increases the level of adrenaline in the blood. This is the best time to take a shower.

In terms of energy: from 5 am to 7 am
the work of the meridian of the large intestine is activated, which is responsible for the final removal of feces from the body with toxins and slags.
After waking up, it is advisable to immediately drink a glass of warm water, drunk on an empty stomach, it helps to moisturize the intestinal tract, stimulates defecation and elimination of toxins. This is especially true for those who suffer from frequent constipation.

07:00 - The stomach is activated: the body requires replenishment of nutrient reserves in order to extract energy from them. Carbohydrates that enter the body are actively decomposed, during this period there is no active fat deposition. The immune defense of the body increases. The chance of infection through contact with viruses is minimal. Increased blood viscosity, increased level of adrenaline in the blood. For cores and hypertensive patients, this is the most dangerous time of day. Physical activity is not recommended. The body's susceptibility to aspirin and antihistamines increases: taken at this time, they remain in the blood longer and act more efficiently.
08:00 - The liver completely freed our body from toxic substances. At this hour, you can not take alcohol - the liver will experience increased stress. Sexual activity is activated. The person is sexually aroused.
09:00 - Mental activity increases, sensitivity to pain decreases. The heart works more energetically. It is not recommended to conduct sports training at this time. The level of cortisol in the blood is very high.

Seasonal rhythms of human organs

In terms of energy:from 7 to 9 am
The meridian of the stomach is actively working. This time is considered ideal for breakfast, the work of the spleen and stomach is activated, so that food is digested very easily. And if you do not have breakfast at this time, then during the hours of the greatest activity of the meridian of the stomach, the empty stomach will have “nothing to do”. With the highest activity of the meridian of the stomach, the level of acids in the gastric juice rises, and an excess of acid harms the stomach and threatens with the occurrence of gastric diseases and a violation of the acid-base balance in the body.

10:00 Our activity is on the rise. We are in the best shape. Such enthusiasm will continue until lunchtime. Do not spray your efficiency, then it will not manifest itself in this form.
11:00 - The heart continues to work rhythmically in harmony with mental activity. The person is not tired. There is an active growth of nails and hair. Increased sensitivity to allergens.

In terms of energy: from 9 a.m. to 11 a.m.
The spleen meridian is active. The spleen is involved in digestion, assimilating and distributing nutrients and fluids extracted from food throughout the body.
The brain is active. Therefore, these hours are called the "golden period", i.e. the most effective in terms of work and study. Don't forget to have breakfast. After breakfast, the spleen absorbs the food coming from the stomach, and the muscles, having received nutrients, become more active. A person has a desire to activate the muscles. When the energy of the muscles and muscles is expended, the work of the spleen is even more activated, and therefore it turns out that this organ is “busy” all the time, loaded with work.

12:00 — There comes the first recession of activity. Decreased physical and mental performance. You feel tired, you need rest. During these hours, the liver "rests", a little glycogen enters the bloodstream.
13:00 - Energy goes down. Reactions slow down. The liver is resting. There is a slight feeling of fatigue, you need to rest. If you have lunch at this time, the food will be absorbed faster.

In terms of energy: from 11 to 13 days
the meridian of the heart is active. During these hours, energy reaches its peak, which can lead to an excess of heart "fire". The easiest way to eliminate this excessive "fire" is to take a little lunch break. This will help replenish energy and increase the efficiency of work in the afternoon. Lunch rest serves to prevent heart disease.

14:00 - Fatigue is gone. An improvement is coming. Efficiency increases.
15:00 - The senses are sharpened, especially the sense of smell and taste. We are entering the workforce. This is the time of partial or complete immunity of the body to drugs. The organs of the body become very sensitive. Increases appetite.

In terms of energy: from 13 to 15 hours
the meridian of the small intestine is active. Nutrients enter the small intestine, where they are processed and broken down, and then transported to various organs of the human body through the blood and lymph capillaries. It is recommended to drink more water to thin the blood and protect the blood vessels.
Weakening of the function of the small intestine not only causes a decrease in energy and blood levels, but also reduces the level of waste excretion.

16:00 - Blood sugar levels rise. Doctors call this condition post-prandial diabetes. However, such a deviation from the norm does not indicate a disease. The second rise in activity. The blood is again enriched with oxygen, the work of the heart and lungs is activated. Favorable time for physical activity and exercise.
17:00 - Maintain high performance. Time for outdoor activities. The efficiency and endurance of the body is approximately doubled. There is an activation of the endocrine system, especially the pancreas. At this time, you can take more food. Due to active digestion and complete breakdown of products, fat will not be deposited.

In terms of energy: from 15 to 17 hours
During these hours, the meridian of the bladder is active, and the bladder is the main channel for the removal of toxins. That is why you need to drink more water during this time. At this time, a person is full of strength and energy. The metabolism in the body reaches a peak, the brain received the necessary portion of nutrients after lunch. Therefore, this time is called the second "golden period" for work and study. Reaches a peak - metabolism.

18:00 “People become less sensitive to pain. Increased desire to move more. Mental vigor gradually decreases.
19:00 - Blood pressure rises. Zero mental stability. We are nervous, ready to quarrel over trifles. Cerebral blood flow decreases, headaches begin.

In terms of energy: from 17 to 19 hours
At this time, the kidney meridian is active. This is the peak period for the removal of toxins from the body, so you should increase the amount of drinking to speed up the appearance of urine and stimulate the elimination of unnecessary and harmful substances from the body. At the same time, the kidneys begin to store the most valuable substances. If a glass of water during these hours becomes your habit, you will improve your kidneys.

20:00 Our weight is at its highest by this hour. Reactions to external stimuli are clear and fast.
21:00 - The activity of the nervous system is normalized. The psychological state stabilizes, the memory becomes sharper. This period is especially good for those who need to memorize a large amount of information, such as texts or foreign words.

In terms of energy: from 19 to 21 hours
are considered the third "golden period" for work and study. At this time, when the pericardial meridian is active, the whole body is at peace. After a light dinner, you can go for a walk. Until 21:00 it is useful to drink a glass of water or weak tea. At this time, the pericardial meridian should be massaged. Massage of the pericardial meridian enhances the function of the heart, as a result of which the activity of all internal organs improves and the circulation of energy and blood is activated.
The Pericardial Meridian is one of the 12 main active channels. It runs along the inside of the arms. You can, for example, sitting in front of the TV, knead the left arm from the armpit down with the right hand - along the pericardial meridian, and then do the same with the right hand. Massage each hand for 10 minutes.

WHY DOES OUR BODY NEED A REST AT NIGHT?

or How to restore the biological clock of sleep?

How to restore the biological clock of sleep

Nature has determined that thirty percent of our lives we sleep: the body needs rest and regeneration. But we often save on sleep, paying for it with psycho-emotional disorders, endocrine disruptions, diseases of the gastrointestinal tract and heart, and sometimes oncology. And if innocent insomnia has looked into your light, this is not only the consequences of a failure of clock rhythms, but also an occasion to think about the REASONS for a whole list of pathologies that inevitably lead us to illness and old age.

At night, the pineal gland (the pineal gland in the groove of the midbrain) produces melatonin - the peak of activity occurs at about 2 am, and by 9 o'clock its content in the blood drops to its minimum values. It is produced by the pineal gland only at night because the active enzymes involved in its production are suppressed by DAYLIGHT. Thanks to melatonin, there is a comfortable decrease in temperature and blood pressure, slowing down their activity and physiological processes. At night, only the liver is actively working - it cleanses the blood of the pathogenic flora of toxins and toxins. Another important hormone, somatotropin (growth hormone), actively begins to work, stimulating cell reproduction, regeneration, rejuvenation and anabolic processes (the release of substances useful for the body from food). Failure to comply with the sleep schedule leads not only to insomnia, oncology and diabetes, but also to early aging of the body ...

Schedule of the body from 22:00 to 4:00

22:00 - Decreased body temperature. The number of leukocytes - white blood cells - increases. In the body of those who go to bed at this time, produce melatonin, the hormone of youth, with a vengeance.
23:00 - If we sleep, then the cells restore their functions. The blood pressure drops, the pulse becomes less frequent. The metabolism slows down. At this time, the body is most predisposed to the occurrence of inflammatory processes, colds, infections. Late eating is very harmful.

In terms of energy: from 21 to 23 hours
At this time, people finish their daily chores and get ready for bed. Therefore, during these hours you need to calm down and provide yourself with a good rest. If you break this natural law, you can harm your health.
If a person sleeps poorly or not enough, he begins to feel bad, he is overcome by lethargy and apathy.
To have quality sleep, you need to fall asleep before 23:00.

24:00 “This is the last hour of the day. If we went to bed at 22 o'clock, then it is time for dreams. Our body, our brain sums up the results of the past day, leaving the useful, rejecting everything unnecessary.
01:00 We have been sleeping for about three hours now, having gone through all the phases of sleep. At one in the morning, a light phase of sleep begins, we can wake up. At this time, we are especially sensitive to pain.

In terms of energy: from 23 to 1 o'clock
active gallbladder meridian. At this time, yin energy gradually dissipates and fades away, but yang energy is born - the most powerful productive life force. If we follow the regime and go to bed before 23:00, then the yang energy quickly arises and rises, which is good for our entire body. If later, then "yang"-energy begins to be wasted. But it is she who is the basis of life.

02:00 – Most of our bodies operate in an economical mode. Only the liver works. It intensively processes the substances we need. And above all those that remove all poisons from the body. The body undergoes a kind of “big wash.
03:00 - The body is resting. Sleep is deep. The muscles are completely relaxed. The pulse and respiration rate decreases, brain wave activity decreases, the heartbeat slows down, body temperature and blood pressure fall. At three o'clock in the morning, energy consumption in the body is replenished.

In energy eskom plan: from 1 to 3 o'clock
At this time, the work of the liver meridian is activated. There is a removal of toxins and slags, as well as the regulation and renewal of blood. The best way to strengthen the liver is quality sleep. The deeper it is, the better the blood circulates and the more actively the liver is cleansed.

Try to follow the daily routine: eat at the same time, wake up at 6:00, go to bed - no later than 22:00 and then you will stay young, healthy and full of energy for a long time! By the way, this is exactly what our ancestors did: they got up at dawn and went to bed at nightfall - probably not only because of the lack of electricity.

We wish you health and prosperity!
