Calculation of human biological cycles. Calculate the calendar of human biorhythms

Rhythmic movement is characteristic of all living nature, all living organisms experience periods of prosperity and intensification of vital activity and periods of its decline and extinction. Scientists around the world are showing great interest in the study and calculation of biorhythms, and the research results allow us to get the most out of this science.

Having calculated your biological rhythms for the next day or a week (month, year) in advance, you can make adjustments to your plans in order to use the capabilities of your body to the maximum, and also not to miss a good time for rest when biorhythms do not have to be active. Using the program is very simple, and the calculation takes only a few seconds - this is the time to enter the date of birth.

What are biorhythms

Biological rhythms are a reflection of the cyclic phenomena of nature by the body. They can be depicted graphically as a curve that will show the ability to perform a certain type of work in the estimated time.

Physiological processes in the body are associated with the alternation of day and night, the least activity at 3-5 o'clock in the morning, and high performance is observed at 10-12 o'clock and in the evening at 16-18 o'clock.

During a person's life, 3 main types of biorhythms accompany:

physical(the cycle is 23 days). As activity increases, endurance, energy increase, and coordination of movements improves. When a decline begins, there may be health problems, a person begins to get tired quickly, a breakdown appears. The last days of the phase are best spent resting.

emotional(28 days). Show mood swings and states of the nervous system. During a recession, mental confusion is observed, the desire to conflict increases, various fears and pessimism appear.

intellectual(33 days). As creativity increases, luck accompanies a person in everything. In the phase of decreasing activity of biorhythms, intellectual activity is inhibited, the reaction rate changes, and the ability to assimilate material decreases.

How to calculate biorhythms for every day

There are special programs for calculating biorhythms (you can download it for free from the link below), but you can also calculate the day of the biological cycle yourself:

The number of years lived, excluding leap years, must be multiplied by 365;
- then count the number of leap years (every 4th year) and multiply it by 366;
- the amount received will show the number of days lived. Dividing it by 23 days (physical cycle) we get a number with a remainder. For example, if the remainder is 18, then the 18th day of the physical cycle of biorhythms is coming. Similarly, you can determine the day of the emotional and intellectual cycles.

There are 6 days in a year when the beginning of two cycles coincide. These days will be quite difficult, and on the 1st day of the year the beginnings of all three cycles of biorhythms coincide, this day will be especially difficult.

During a person's life there are periods of the highest activity of biorhythms, these years were called akme. For men, they repeat every 3 years, starting from the age of 15-16, for women - every 2. For these periods, you can calculate and find out the sex of the unborn child. If both parents are in the 2nd year after acme, for example, then it is likely that a boy will be born. If it's a year after acme, it's a girl.

Birthday is considered a turning point from trouble to joy, and the first month after the birthday is the most favorable. The 5th and 9th (10) months will also be favorable. The 2nd and 12th (especially) months after the birthday will be unfavorable.

Free program for calculating human biorhythms

To facilitate the task, a program was developed that allows you to calculate your biorhythms for every day, the program is free and can be downloaded. It does not require installation, it works on any version of Windows, and it is very easy to work with the program - enter your date of birth and get the result of calculating biorhythms for today. To find out the results for any other day, you need to enter the desired date in the appropriate field. All. So simple.

The archive with the program contains instructions and a link to the developer's website. You can run the program directly from the archive without unpacking it.

So, why is the calculation of biorhythms for In-contri more accurate, or coincides with other reliable sources? Because all 7 biorhythms corresponding to 7 chakras are used in the calculation, and the values ​​are refined to 4-6 decimal places. These clarifications do not affect the daily analysis so much, but if you calculate the compatibility between people whose age differs by 3, 5 or even 10 years, then the exact periods play a significant role in the result. Here are the periods for calculation that are used on In-contri:

Physical - 23.6884 days - corresponds to the lower Muladhara chakra

Emotional - 28.426125 days - the second chakra of Svadhisthana

Intellectual - 33.163812 days - the third chakra of Manipura

Heart - 37.901499 days - fourth chakra Anahata

Creative - 42.6392 days - fifth chakra Vishuddha

Intuitive - 47.3769 days - sixth chakra Ajna

Higher chakra - 52.1146 days - the seventh chakra Sahasrara

Immediately different from all other approaches: we will not have values ​​from -1 to 1, which the biorhythm sinusoid takes. All values ​​will be positive. Only our scale from 0% to 100%. Later you will also understand why this is so.

For those who want to know now: let’s say from experience that it’s hard psychologically to constantly see “cons” in your schedule. Some have even become depressed because of it. Therefore, to maintain sobriety of mind, it is better to let everything be in percentage terms.

We only ask you not to be too fanatical when examining the result of calculating your biorhythms. The fact is that I had to deal with people who “calculated” every step of their biorhythms so much that it was not they who began to use this really useful tool, but he them. Although the purpose of biorhythms is not at all. If you use them wisely, as, by the way, even some professional athletes do when calculating their physical biorhythm, then you can get good results and avoid obvious mistakes in actions.

A Brief History of Biorhythm Research

The history of the appearance of biorhythms does not carry anything mystical. Three medical scientists independently observed in their patients the rhythms of activity of certain spheres (physical, emotional and intellectual), recorded them, compared them with each other, with the date of birth of each patient and analytically arrived at ... different periods. Actually, on these differing data, the first programs on biorhythms were built in the 70-80s and a real boom in interest in this not at all trivial theory began. The situation is similar to the one that has developed in astrology: there were many charlatans and "online calculators", the results were different for everyone, and there was no understanding of how it works. Probably the most offensive thing is that at the dawn of the twentieth century, it was our compatriots who were the pioneers in the study of biorhythms, and, many years later, already at the end of the century in our country, after the fall of the Iron Curtain and the influx of astrologer magicians in the fifth generation, the topic of biorhythms was just as trampled into the mud as professional astrology. One of the last nails in the coffin of biorhythms in Runet was the well-known Biorhythms Online program with a yellow smiley icon. The mass nature of its first erroneous version did its job: people entered their dates of birth, dates of birth of partners, got awkward results and abandoned this topic because it simply did not work. On that moment.

However, in the West, this fascinating theory, which once began from nothing but hypotheses and approximate results of experiments, has found a second life. In particular, they have long drawn a parallel between biorhythms and chakras and derived the formula of biorhythms through the number Pi, thanks to which everything fell into place. There are no more disputes about how to call this or that rhythm, when everything is already known about the 7 chakras, there are no more periods of 28 or 27 days, but there are the exact values ​​of the periods that are used in all calculations on the In-contri website.

Disputes over periods of biorhythms are now reminiscent of disputes about the lunar cycle, which is not 27 or 28 days, as they even write in some books, but 27.32166 days.

Therefore, friends, anticipating your questions in the spirit of “why is it so here and so there”, we answer: where the results are the same, the periods are correct, where the results are different, they are not correct. The most interesting thing is that in the second version of the popular calculator "Biorhythms Online 2.0" 10 years ago there was an attempt to rehabilitate for the first version - they nevertheless set specified periods. It is a pity that the program was not saved.

Prince Charles was born on November 14, 1948 and Princess Diana on July 1, 1961. Compatibility of intellectual rhythms - 85%
emotional rhythms - 70%
physical rhythms - 17%
The average percentage is 57.

Analysis. A beautiful love story with a tragic ending. Unfortunately, many apparently successful marriages (or love relationships) end in car accidents. The high compatibility of intellectual and emotional rhythms can overwhelm partners with a sea of ​​feelings, intoxicate and raise them to unprecedented heights. But the holiday ends sooner or later, there comes a hangover with the name "sex". With this compatibility of physical rhythms, there is no need to talk about harmonious sexual relations. Sooner or later there are partners (old and not so) who open up new, brighter facets of intimate relationships...

And Byron is right, noticing gloomily,
What the world owes, as a gift,
To that once Laura
She did not marry Petrarch.
I. Huberman

Bill Clinton was born August 19, 1946 and Hillary was born October 26, 1948.
Intelligent - 99%
Emotional - 8%
Physical - 30%

Analysis. Marriage of convenience. This is what he rests on. There is no need to talk about feelings. Problems of a sexual nature. In such a marriage, the woman suffers especially. But without his wife, Clinton would hardly have become president. And without it, it will be lost. This family will keep on counting. It is interesting to check the compatibility of the former president with Monica Lewinsky, born July 23, 1973:
Intellectual - 22%
Emotional - 50%
Physical - 98%

Such compatibility is only suitable for sexual relations: you can achieve the highest pleasure. Nice addition to my wife. If the compatibility of emotional rhythms was greater, Lewinsky would hardly talk about her relationship: she would silently love, suffer and look for meetings.

It is very interesting to consider love triangles from the point of view of compatibility of biorhythms. This is my favorite topic. As a rule, biorhythms very well show the problem areas of human relationships. In my life, I only twice encountered people who had good biorhythm compatibility with both their spouse and lover.

  • Alla Pugacheva was born April 15, 1949. With Vladimir Kuzmin (May 31, 1955) compatibility:
    intellectual rhythms - 92%,
    emotional - 80%,
    physical – 29%.
    With Philip Kirkorov (April 30, 1967) a similar situation:
    intellectual - 92%,
    emotional - 99%,
    physical - 0% (zero).
    Maxim Galkin was born on June 18, 1976:
    intellectual - 69%,
    emotional - 16%,
    physical – 71%.
    No comments.
  • Madonna(August 16, 1958) with her first husband Sean Penn (August 17, 1960) had the following compatibility:
    intellectual - 85%,
    emotional - 88%,
    physical - 43%.
    This couple lacked sexual harmony. It cannot be said that it was completely, but it has never been complete either. Their daughter Lourdes should be involved in sports, dancing or aerobics. With Guy Ritchie (September 10, 1968) the situation is more harmonious:
    intellectual - 96%,
    emotional - 57%,
    physical – 71%.
    It happens, of course, that compatibility is even higher, but common sense and mutual respect will allow this couple to live in harmony for decades.
  • Tom Cruise born July 2, 1962, Mimi Rogers - January 27, 1955:
    intellectual - 68%,
    emotional - 0.5%,
    physical - 17%.
    With Nicole Kidman (June 20, 1967):
    intellectual - 22%,
    emotional - 80%,
    physical - 8%.
    With Katie Holmes (December 18, 1978):
    intellectual - 85%,
    emotional - 25%,
    physical - 43%.
    "And the same rake greets me" V. Vishnevsky. Cruz will have to continue his search.
  • Demmy Moor(November 11, 1962) with Bruce Willis (March 19, 1955) was connected by an apparently strong physical attraction:
    intellectual - 31%,
    emotional - 0.5%,
    physical - 100%.
    With Ashton Kutcher (February 7, 1978) compatibility is much better:
    intellectual - 99%,
    emotional - 68%,
    physical - 98%.
    So it would be right away! But Kutcher then walked under the table on foot.

You can find many more famous couples, but I do not see the need for this. You have the opportunity to practice both in calculations and in analysis. If you compare the results of different methods, there may be discrepancies with the Internet program. It included average coefficients for three biorhythms. But the error is only a few percent.

Biorhythms - the cyclical nature of processes in a living organism. The main external rhythms that affect human biocycles are natural (Sun, Moon…) and social (working week…) Leading internal chronometers of the human body are located: in the head (pineal gland, hypothalamus) and in the heart. Biorhythms can change, synchronizing with external rhythms - cycles of illumination (change of day and night, light).

A person from the day of birth is in three biological rhythms - physical, emotional and intellectual:

23 day rhythm- this is a physical rhythm, it determines the health, strength and endurance of a person;
28 day rhythm- this is an emotional rhythm, it affects the state of the nervous system, mood, love, optimism, etc .;
33 day rhythm is an intellectual rhythm. It determines the creative abilities of the individual. Auspicious days of the 33-day rhythmic cycle are characterized by creative activity, luck and success accompany a person. On unfavorable days, there is a creative decline.

Each of the three long-term rhythmic cycles begins at birth. Its further development can be depicted as a sinusoid (graph). The higher the curve rises, the higher the ability corresponding to this mark. The lower it falls, the lower the corresponding energy. Periodic days are considered critical when the curve is at the intersection of the scale. This is an unfavorable time.

Thus, calculation of biorhythms quite uncomplicated. Starting from the exact date of your birth, count how many days you have lived. To do this, multiply 365 days in a year by the number of years lived, and multiply the number of leap years by 366 days. Leap were: 1920, 1924, 1928, 1932, 1936, 1940, 1944, 1948, 1952, 1956, 1960, 1964, 1968, 1972, 1976, 1980,1984, 1988, 1992, 1996, 2000, 2004, 2008, 2012 , 2016.

Calculate the total number of days lived. Now you know how many days you have been living in this world. Divide this number by the number of days of the biorhythm you want to calculate: 23, 28, 33. The remainder will show you where you are currently on the curve. For example, if the remainder is 12, then the 12th day of the biorhythm that you consider is coming. This is the first half of the cycle, usually it is favorable. If the cycle is at chart zero, then it's a bad day. In addition, the days when the biorhythm lines cross the horizontal line in the center of the graph are the so-called critical days, when your abilities are completely unpredictable. A person on such days feels a breakdown and lack of energy.

Each biorhythm has 3 periods: high energy period, low energy period and biorhythm critical days. Let's take a closer look:

23 day rhythm

High energy (0-11 days): good physical health, resistance to stress, disease and high vitality, strong sex drive, danger of overestimating one's strength.
Low energy (12-23 days): increased fatigue, at this time it is recommended to rest more and conserve energy.
Critical days (11, 12, 23 days): reduced resistance to disease, a tendency to erroneous actions.

28 day rhythm

High energy (0-14 days): intense emotional and spiritual life, favorable time for friendship and love, increased creativity and interest in new things, a tendency to heightened emotionality.
Low energy (14-28 days): self-doubt, passivity, underestimation of one's capabilities.
Critical days (14, 28 days): a tendency to mental conflicts, a decrease in resistance to disease.

33 day rhythm

High energy (0-16 days): ability to think clearly and logically, ability to concentrate, good memory, creative activity.
Low Energy (Days 17-33): Decreased interest in new ideas, slow reaction times, creative decline.
Critical days (16, 17, 33 days): inability to concentrate, inattention and absent-mindedness, prone to erroneous actions (higher probability of accidents).

HUMAN BIOLOGICAL RHYTHMS

Daily rhythms according to the "biological clock"

EARLY MORNING

4-5 hours (in real, geographic time, as for acupuncture points) - the body is preparing for awakening.

By 5 o'clock in the morning, melatonin production begins to decrease, body temperature rises.

Shortly before waking up, at about 5:00 am according to geographic, real local time, the body begins to prepare for the upcoming wakefulness: the production of "activity hormones" - cortisol, adrenaline - is increasing. In the blood, the content of hemoglobin and sugar increases, the pulse quickens, blood pressure (BP) rises, breathing deepens. Body temperature begins to rise, the frequency of REM sleep phases increases, and the tone of the sympathetic nervous system increases. All these phenomena are enhanced by light, heat and noise.

By 7-8 o'clock, the "owls" have a peak in the release of cortisol (the main hormone of the adrenal glands) into the blood. In "larks" - earlier, at 4-5 hours, in other chronotypes - about 5-6 hours.

From 7 to 9 in the morning - rise, physical education, breakfast.

9 hours - high performance, fast counting, short-term memory works well.

In the morning - the assimilation of new information, with a fresh mind.

Two or three hours after waking up - take care of the heart.

9-10 am - time to make plans, "wiggle your brains." "The morning is wiser than the evening"

9-11 h - immunity increases.

Effective drugs that increase the body's resistance to disease.

Up to 11 hours - the body is in excellent shape.

12 - reduce physical activity.

The activity of the brain is reduced. Blood rushes to the digestive organs. Gradually, blood pressure, pulse and muscle tone, respectively, begin to decrease, but body temperature continues to rise.

13 ± 1 hour - lunch break

13-15 - noon and afternoon rest (lunch, "quiet time", siesta)

After 14 hours - minimal pain sensitivity, the most effective and long-lasting effect of painkillers.

15 - long-term memory works. Time - to remember and remember well the right thing.

After 16 - the rise of working capacity.

15-18 hours - it's time to go in for sports. Thirst, at this time, plentifully and often quench with clean boiled water, hot or warm - in winter (for the prevention of colds, gastrointestinal diseases and kidney diseases). In the summer you can also cold mineral water.

16-19 - high level of intellectual activity. Housework

19 ± 1 hour - dinner.

Carbohydrate food (natural - honey, etc.) contributes to the production of a special hormone - serotonin, which favors a good night's sleep. The brain is active.

After 19 hours - good reaction

After 20 hours, the mental state stabilizes, memory improves. After 9 pm, the number of white blood cells almost doubles (immunity increases), body temperature drops, and cell renewal continues.

From 20 to 21 - light physical education is good for health, walking in the fresh air

After 21:00 - the body prepares for a night's rest, the body temperature drops.

22:00 is time for sleep. Immunity is strengthened to protect the body during the night's rest.

In the first half of the night, when slow sleep prevails, the maximum amount of somatotropic hormone is released, which stimulates the processes of cell reproduction and growth. No wonder they say that in a dream we grow. There is a regeneration and cleansing of body tissues.

2 hours - those who do not sleep at this time may be depressed.

3-4 hours is the deepest sleep. Minimum body temperature and cortisol levels, maximum melatonin in the blood.

Biological rhythms in life

Air travel from east to west is easier than from west to east. For adaptation to the body (young, healthy) it takes about a day for each time zone, but not less than three to four days. The rate of capturing the biorhythms of the human body by the external rhythm strongly depends on the difference in their phases. On average, it takes one and a half weeks for sufficient adaptation and acclimatization in new conditions. It does not depend on the position of the hands on the clock face, but on the sun above your head. The local, local features of the geomagnetic and other fields and radiations, which differ from the usual ones, also noticeably influence.

The daily chronotype of a person: morning (larks), daytime (pigeons) and evening (owls). The night activity of "owls" affects their health - myocardial infarctions occur more often in them than in "larks", their cardiovascular system "burns out" faster.

To increase productivity, labor efficiency, it is recommended to take into account the chronotype, individually for each employee, when drawing up a schedule, work schedule for personnel at enterprises, and especially for dispatchers and operators.

Compliance with sanitary and hygienic standards and ergonomic requirements, work and rest regimes is a necessary condition for the operation of a modern enterprise.

Efficiency sharply decreases from thirty degrees of heat, Celsius, halving at an ambient temperature of + 33-34 ° C.

Shift work schedule (for example, from a night shift to a day shift) - no more than once a month, taking into account the time required for adaptation (1-2 weeks).

Accidents at work and traffic accidents on the road more often occur at certain hours:
- from 22 hours to 4 hours - a person has the lowest response rate.
- between 13 and 15 hours - first, general pre-lunch rush, after - "afternoon depression".

For the prevention of "afternoon depression", rest after lunch, lasting 10-20 minutes, or "midday nap", but not more than 1.5 hours, may be effective, otherwise there will be a reverse effect.

The working capacity of a person is higher from 10 to 12 and from 17 to 19 hours.

Sport

“Specially conducted studies and the practice of sports training show that the most favorable period for intense training is from 9 to 18 hours and that it is undesirable to carry out loads that are large in volume and intensity early in the morning and late in the evening” (N.A. Agadzhanyan et al., 1989 ).

Human biorhythms: Sleep

Try to go to bed and always get up at the same time. Otherwise - desynchronosis. The first 4-5 hours of normal, natural sleep (deep, without breaks) are mandatory, this is a vital daily minimum for the human body.

For insomnia and for quick falling asleep (normal - within 5-15 minutes):
1) lie down more comfortably, close your eyes, do not think about anything (reduce the bioelectrical activity of the brain);
2) focus your attention on the diaphragm (its movement during breathing) and on the inner ankles (ankles) of the legs.

For a sound sleeper, the main source of sensory information about the environment is the ears (“light sleep”), therefore, in order not to wake up from noise, silence must be ensured (including using anti-noise soft “ear plugs” made of hypoallergenic polymer, having good SNR (noise reduction), at a level of 30 dB or more), given the increased sensitivity of hearing at night - with eyes closed and during sleep (10-14 decibels better compared to daytime). Loud, sharp, frightening sounds - can wake the sleeper for a long time and cause insomnia.

It is difficult to fall asleep on an empty stomach, therefore, dinner is around 18-20 hours or 2-3 hours before bedtime. Do not overeat at night. The usual duration of restful sleep is 7-9 hours. Not only its duration is important, but also its quality (continuity and depth of the first three, mandatory cycles, 1.5 x 3 = 4.5 hours)

Poor, restless sleep, nightmares, with a repetitive obsessive plot - may be the result of cardiovascular diseases (bradycardia - a rare pulse, arrhythmias), symptoms of snoring and respiratory arrest disease (sleep apnea), lack of oxygen in the room. The aeroion composition of the air in apartments, without ventilation or the use of an air ionizer, also needs to be improved.

Before waking up, a dream-movie is seen (its reproduction is a release of the ballast of nervous tension, unrealized ideas, unpleasant visual pictures that have accumulated over the past days, after processing and ordering the information received in the short-term and long-term memory of the brain, adaptation to difficult life situations). The more intense the eye movements during REM sleep, the better the dream is reproduced. At the moment of falling asleep, a series of slides or pictures appears in the mind.

Laboratory studies have shown the need for REM sleep - for the survival of the body. A mouse deprived of this phase of dreams for 40 days died. In humans, when blocking REM sleep with alcohol, there is a predisposition to hallucinations.

Dreams, in the phase of "REM sleep" (after slow-wave sleep and before waking up, to rise or to "turn on the other side"), appear, according to an individual biorhythm - every 90-100 minutes. (in the morning - the cycles are reduced to the first tens of minutes, see the graph in the picture), in accordance with the intraday cyclicity of the change (increase) in the overall body temperature and the redistribution of blood in the body (from its periphery, from the extremities to the center of the body, inside), the growth of blood pressure, respiratory rate and heart rate.

Short-term memory is involved in remembering dreams, therefore, up to 90% of the content of a dream is forgotten within the next half hour, after waking up, unless, in the process of remembering, emotional experience, ordering and comprehension, its plot is not recorded in the long-term memory of the brain.

Human biorhythms: remembering sleep

According to enthusiastic researchers practicing at high levels, lucid dreaming (OS) is cooler than many modern computer games.

Many people see dreams, but not all of them try to remember and remember them at the moment of waking up (especially during short awakenings between the first cycles, before returning back to slow sleep).

If there is very little time for rest, you can sleep from 10-11 pm to 3-4 am (“mandatory program” - the first three night cycles in a row, unwaking, that is, the duration of sleep will be 4-5 hours). In this case, the following are restored, sequentially: the brain, body and physical strength, the emotional sphere.

The duration of night sleep necessary for the human body also depends on the season. In winter - it should be at least half an hour longer than in summer.

Natural sleeping pills are fatigue and/or certain moments in the 90-minute cycles of the individual biorhythm of the body when the body temperature drops.

Sufficient night sleep contributes to weight loss (with excess weight - its normalization). In this case, dinner no later than four hours before bedtime. Night food - is excluded, you can only - drink clean water, in a small amount (for washing the esophagus, avoiding dehydration and for falling asleep as soon as possible). The effect will be more noticeable - with high physical activity, during daylight hours.

From frequent lack of sleep - the body wears out faster and ages. During the slow-wave stage of normal, deep sleep, the brain scans the digestive, respiratory systems and heart (as having the clearest rhythm), and during the fast-wave stage, the cardiovascular and lymphatic, reproductive and nervous systems, as well as the liver, kidneys, muscles and tendons (i.e., organs that do not have obvious short-term rhythms). After collecting and processing this information, a sequentially planned and coordinated restoration of the viscera (visceral sphere - stomach, intestines, etc.) of the body is carried out. In this process, mainly the most powerful "computing processors" are involved, for example, in the visual and motor areas of the cerebral cortex. In the case when you really want to sleep, but, systematically, there is no such possibility - physical changes may occur in the internal organs and the risk of developing pathologies (stomach ulcers, etc.) is significantly increased.

A sleepy and very tired person who is sleepy while driving a car also risks his health and is dangerous to others, just like a driver who is in a state of intoxication.

Scientists, and not only British ones, have found that it is possible to slow down the aging of the brain if you stabilize your biorhythms - by simply observing the sleep pattern, this natural circadian (that is, cyclically repeating every day, every 24 hours) rhythm.
