Biorhythms: characteristics and their role in human life

We reg­u­lar­ly wind our wrist­watch­es, change the bat­tery in them or recharge them if it is a lat­est gen­er­a­tion device. And how do you feel about the most impor­tant chronome­ter — an organ­ism that counts bio­rhythms? Neglect of its require­ments can lead to the most unfor­tu­nate con­se­quences — from obe­si­ty to can­cer. And here’s how it hap­pens.

What it is?

The bio­log­i­cal rhythms of a per­son are count­ed by his “inter­nal clock”. Each cell in our body lives accord­ing to its own spe­cial sched­ule. It is based on sev­er­al fac­tors: exter­nal (weath­er, sea­son, work­ing and rest con­di­tions) and inter­nal (gen­er­al health, mood, habits, etc.).

By the way, bio­rhythms are found in almost all liv­ing things in nature. The rose “knows” when it’s time to blos­som, the bear — when to hiber­nate. This hap­pens sim­ply because this is how it should hap­pen, nei­ther ani­mals, nor even plants, are try­ing to vio­late the laws of their body. But a per­son tries to do it reg­u­lar­ly. Although it is espe­cial­ly impor­tant for him to take into account the exis­tence of bio­rhythms in every­day life.

The con­cept of “bio­log­i­cal rhythms” in sim­ple words can be described by anal­o­gy with the change of day and night in a day. If you look at this process in the con­text of phys­i­ol­o­gy, then you should pay atten­tion to how we breathe — inhale-exhale. It nev­er occurred to you to change this rhythm, well, unless, of course, you are engaged in scu­ba div­ing. Imag­ine what would hap­pen if in biol­o­gy some­one began to live not accord­ing to the laws of the sea­sons, but con­trary to them. After all, it is impos­si­ble to har­vest pota­toes in cen­tral Rus­sia in Feb­ru­ary.

But in the psy­chophys­i­ol­o­gy of man, attempts are being made. We try to work at night, sleep only a few hours, break the diet, snack­ing on the run. As a result, our bio­rhythms go astray, which leads to a lot of prob­lems. How to set the inter­nal clock? First, let’s look at the device of their mech­a­nism.


As in nature there are dif­fer­ent cycles, so the types of human bio­rhythms are divid­ed into types of dif­fer­ent dura­tion. There are 3 forms in total.

  1. The short­est ones are called ultra­di­an bio­rhythms. Their dura­tion varies from one sec­ond to sev­er­al hours, but not more than 24. These include process­es such as meals, the work of the entire diges­tive sys­tem, breath­ing, heart­beat, and so on.
  2. Fur­ther on the dura­tion, dai­ly bio­rhythms are dis­tin­guished. They are also called cir­ca­di­ans. They are cre­at­ed by the lev­el of hor­mones and oth­er blood indi­ca­tors, the process­es of sleep and wake­ful­ness, fluc­tu­a­tions in body tem­per­a­ture depend­ing on the time and state of the body, and oth­er process­es that repeat with us every day.
  3. The longest bio­rhythms are called infra­di­an. Their dura­tion can range from a week to a year.

This includes changes due to chang­ing weath­er con­di­tions, and the reduc­tion or increase in day­light hours, and oth­er sea­son­al changes depend­ing on the time of year, this also includes wom­en’s cycles.

Thus, on our bio­rhythms every sec­ond are influ­enced by many fac­tors — both inter­nal and exter­nal. Exam­ples of both the first and sec­ond can be list­ed indef­i­nite­ly. Almost every cell lays bio­rhythms inside us, they depend on the work of all organs, the endocrine sys­tem, and men­tal state. These indi­ca­tors can change dur­ing the day, and can remain con­stant for a long time.

There are states that repeat with us from day to day or from year to year. Such nat­ur­al phe­nom­e­na as rain or snow cause sad­ness in some, a roman­tic mood in oth­ers. And the lunar phas­es affect not only the gen­er­al con­di­tion of the body, but also its indi­vid­ual parts. It is known that hair and nails grow bet­ter when the moon goes to increase, and vice ver­sa, at the moment when it turns into a month, the growth process almost stops. There­fore, many have long learned to adapt to this lunar cal­en­dar.

Spe­cial prop­er­ties in cer­tain peri­ods are shown not only by peo­ple, but also by plants.. It is no coin­ci­dence that avid sum­mer res­i­dents and gar­den­ers always have a lunar cal­en­dar at hand, every day it is char­ac­ter­ized by cer­tain plus­es and minus­es for a par­tic­u­lar group of flo­ra. Fol­low­ing in step with nature, it is pos­si­ble to draw up a sched­ule of adap­tive mea­sures not only for the flow­er­ing, but also for the human body. In addi­tion, our bio­rhythms, like flow­ers, are sen­si­tive to sun­light.

Sim­ply put, the short­est clas­si­fi­ca­tion with ultra­di­an bio­rhythms reacts to our every sneeze, annu­al bio­rhythms live more accord­ing to the laws of nature than depend­ing on the inter­nal needs of the human body.

How to know your biorhythms?

Deter­min­ing which day your bio­rhythms work one hun­dred per­cent, and when they require rest, is not so dif­fi­cult. To cre­ate a kind of sched­ule of all indi­ca­tors, you need to use one of the many pro­grams or appli­ca­tions for your smart­phone. All of them will pro­vide a table or dia­gram show­ing when your body is ready for men­tal work, when for phys­i­cal work, and when for cre­ative work. The ini­tial data are used the same. The first is your date of birth. After that, the pro­gram applies a cer­tain for­mu­la.

If you real­ly want to, you can do the cal­cu­la­tions your­self, but why do we need it when the 21st cen­tu­ry is in the yard, and smart machines are ready to come to our aid at any moment. Yes, and it is much eas­i­er and faster for them to deter­mine the cycles of our bio­rhythms. What real­ly needs to be kept in mind is the length of the major human cycles. Each indi­ca­tor has its own peri­od.

  1. Phys­i­cal the cycle, the one that deter­mines our strength and endurance, is 23 days.
  2. Emo­tion­alwhich is “respon­si­ble” for our mood and men­tal state, lasts 28 days.
  3. Intel­lec­tu­al affects our abil­i­ty to engage in cre­ative and men­tal activ­i­ties, it is the longest — 33 days.

Print the result­ing graph and fol­low your bio­log­i­cal rhythms. They will tell you when to clean up or go to the gym, when to go on a roman­tic date, and when to start writ­ing an arti­cle (book, pic­ture, song). It is also rec­om­mend­ed to make the same charts for your chil­dren. So it will be eas­i­er to sched­ule class­es in the sports sec­tion and in the music school.

Yes, and it will be use­ful to com­pare your own bio­rhythms with how they are set up among loved ones. Then it will be eas­i­er for you to find a com­mon lan­guage, share house­hold chores and avoid unnec­es­sary dis­putes and con­flicts.

Effect on the body

Our bio­rhythms affect not only our abil­i­ty to do any­thing at any giv­en time, but also our health. For exam­ple, a food cul­ture ensures order in the work of the gas­troin­testi­nal tract. Exper­i­ments such as fast­ing affect his activ­i­ty neg­a­tive­ly. It would seem that peo­ple often resort to such meth­ods for los­ing weight, and the result is often not encour­ag­ing.

The thing is that in this way we dis­rupt the func­tions of all diges­tive organs. They “do not under­stand” what to do due to the fact that they were left “with­out a job”. Then, when they need to process food again, they stop work­ing in full. There­fore, before try­ing to “deceive” your body, you need to care­ful­ly weigh the pros and cons, even bet­ter — con­sult a spe­cial­ist.

Oth­er­wise, you can severe­ly dam­age the mech­a­nism of your own inter­nal clock and, as a result - dis­rupt the meta­bol­ic process, which will inevitably lead to a set of extra pounds. Hav­ing stud­ied their own bio­rhythms, many make adjust­ments to their own life. So, in sports, coach­es and ath­letes them­selves often make a sched­ule of class­es, tak­ing into account the pecu­liar­i­ties of the sched­ule of bio­log­i­cal rhythms.

In the West, spe­cial­ists have com­plete­ly estab­lished a con­nec­tion with the choice of pro­fes­sion. That human­i­ty is divid­ed into three types - larks, owls and pigeons, if not every­one knows, then almost every­one. For the sec­ond, we will explain that the first are those who get up ear­ly enough, their per­for­mance is espe­cial­ly great in the morn­ing, but clos­er to 10 o’clock in the evening they should already be in bed. The lat­ter, on the con­trary, are ready to work until mid­night, and in the morn­ing they look more like sleepy flies than viable employ­ees.

Sci­en­tists have cal­cu­lat­ed that about a quar­ter of the world’s pop­u­la­tion are larks, and more than 40% are owls. All the rest are a mixed type, which is called pigeons. So, in some com­pa­nies, before hir­ing, they check the bio­log­i­cal clock of the appli­cant. Sky­larks will nev­er be hired on the night shift, and owls will nev­er be trust­ed with a task that must be com­plet­ed by din­ner. Thus, labor pro­duc­tiv­i­ty increas­es not only for a par­tic­u­lar per­son, but also for the enter­prise as a whole.

Ide­al­ly, we need to con­sid­er each spe­cif­ic fac­tor that is influ­enced by our bio­rhythms.

Physical state

As not­ed above, bio­log­i­cal rhythms affect per­for­mance in gen­er­al. The phys­i­cal cycle deter­mines when it is best to exer­cise and when to stop vig­or­ous activ­i­ty. The curve of your bio­rhythms will help deter­mine at what time of the day, week and month your abil­i­ty to work is at its high­est lev­el, and when it is bet­ter to leave all things that require at least some phys­i­cal effort, because it will not be pos­si­ble to achieve a sig­nif­i­cant result at these moments any­way.

Emotional condition

Vio­la­tion of the emo­tion­al cycle will lead to reduced men­tal activ­i­ty, affect mood, and can even lead to changes in behav­ior pat­terns. A per­son will get up “on the wrong foot” every day, so you sim­ply won’t have to wait for bril­liant ideas from him at work or a kind word at home. Hence the ner­vous break­downs both in him­self and in the peo­ple around him.


Our brain also acts accord­ing to its own bio­rhythm chart. Have you ever thought about why some­times we can’t find a solu­tion in any way, and lit­er­al­ly after an hour or two we issue it and under­stand that it prac­ti­cal­ly lay on the sur­face? The whole point is that at a cer­tain time of the intel­lec­tu­al cycle, our men­tal abil­i­ties are not even at zero, but in a deep minus.

There­fore, hav­ing stud­ied the sched­ule, you can eas­i­ly under­stand when it is worth start­ing to solve dif­fi­cult tasks, and when it is bet­ter to refuse them, not to waste time in vain and devote it to oth­er activ­i­ties, of which you prob­a­bly have a lot.

Causes of violations

Bio­log­i­cal rhythms, as not­ed ear­li­er, depend on both exter­nal and inter­nal fac­tors.. They are affect­ed by both weath­er con­di­tions and diet. The dis­or­der can cause star­va­tion, exces­sive eat­ing. Both can seri­ous­ly change the meta­bol­ic process, and it will be very dif­fi­cult to restore it.

A seri­ous fail­ure gives a vio­la­tion of the dai­ly rou­tine. The shift is more like­ly to hap­pen if you have to change time zones. Hav­ing vis­it­ed a coun­try where there is a big dif­fer­ence in time, you will cer­tain­ly feel that your inter­nal clock has gone astray. And now we will con­sid­er these and some oth­er rea­sons that affect the work of the indi­vid­u­al’s inter­nal chronome­ter in more detail.


Time with­in us is the basic ele­ment of all life activ­i­ty. By trans­lat­ing the hands of this clock, you will change the phys­i­o­log­i­cal state of the body as a whole. There­fore, before tak­ing on night work, think care­ful­ly about what your body will lead to lat­er. If you do not tend to spend the night active­ly, then the like­li­hood that you will soon devel­op chron­ic fatigue syn­drome is very high.

When choos­ing a coun­try for trav­el, pay atten­tion to the time dif­fer­ence, remem­ber that when you return home, you will cer­tain­ly have to read­just your bio­log­i­cal rhythms. There­fore, leave at least a cou­ple of days for this and do not rush to work imme­di­ate­ly after you have arrived from the oth­er side of the world. When trav­el­ing, try not to dis­rupt your meal, sleep, and wake sched­ules too much. And, of course, always stick to the regime at home.


Ecol­o­gy is one of the rea­sons that experts name when they detect a vio­la­tion in the work of the bio­rhyth­mic sys­tem. Of course, it will not be pos­si­ble to solve all envi­ron­men­tal prob­lems at once, and even alone. How­ev­er, they can be fought.:

  • more often be out­doors — in the for­est or in the coun­try;
  • start help­ing nature from your­self — try sort­ing garbage, for exam­ple, orga­nize clean­ing in the yard, the Uni­verse will cer­tain­ly answer you with grat­i­tude and send you pos­i­tive ener­gy that will strength­en your inner strength and will not let the inter­nal clock mech­a­nism go astray.

Anoth­er exter­nal fac­tor is the change of sea­sons. In our coun­try, autumn, as you know, is a dull time. If you are affect­ed by it, then it is best to go on vaca­tion to warmer and sun­nier coun­tries dur­ing the most pro­longed rains and chilly weath­er. If this is not pos­si­ble, bright­en up your life at home.

Use more pow­er­ful light bulbs, dec­o­rate the apart­ment with flow­ers, fill it with pleas­ant smells with the help of incense sticks. If you ignore all this and let inter­nal time take its course, then you can lose it.


The loss of bio­log­i­cal rhythms can lead to many prob­lems. This and malaise, and dis­abil­i­ty, and men­tal dis­or­ders. If you feel symp­toms such as fatigue, drowsi­ness, or, con­verse­ly, insom­nia, loss of appetite, or an exces­sive desire to eat every­thing that catch­es your eye, urgent­ly check your con­di­tion with your inter­nal clock and start repair­ing the mech­a­nism.

How to recover?

First of all, you should restore the usu­al dai­ly rou­tine. It must be tai­lored to indi­vid­ual needs. Before set­ting the body to work prop­er­ly, count your bio­rhythms. Only then pro­ceed to draw up a per­son­al sched­ule of work and rest.

Take con­trol of your body into your own hands. You can change its state only if you cor­rect­ly dis­trib­ute cas­es accord­ing to indi­vid­ual char­ac­ter­is­tics. Night dis­cos are con­traindi­cat­ed for larks, and morn­ing jog­ging for owls is con­traindi­cat­ed. How­ev­er, this does not mean that phys­i­cal activ­i­ty should be com­plete­ly aban­doned. Doing sports not only helps in shap­ing the body, they help to strength­en the spir­it and bio­log­i­cal rhythms too.

The reg­u­la­tion of the inter­nal clock will not hap­pen until you begin to lis­ten to them and live accord­ing to the laws of their time. Try to go to bed and get up at the same time. The same applies to food intake.

Go on vaca­tion around the same time. Do not arrange unnec­es­sary shocks to your body. You don’t bang your wrist­watch against the wall, even if it’s shock­proof. So why endan­ger your own body? Give him more fresh air. Walk more and ven­ti­late the rooms in which you live and work dai­ly.

It will be good if you start talk­ing to your inner self through med­i­ta­tion. In any case, lis­ten to the desires of your body more often. Let him rest, give gifts in the form of mas­sages and spa treat­ments. Please him with use­ful prod­ucts. Do not poi­son with a large amount of fat, espe­cial­ly at night. The diges­tive sys­tem, like the brain, also needs sleep.

Do not knock down bio­rhythms by flood­ing all the cells of your body with alco­hol, such mois­ture is def­i­nite­ly con­traindi­cat­ed for him. But drink clean water at least 1.5–2 liters per day.

Take up yoga, enroll in a dance school or a gym. Use herbal infu­sions as “fer­til­iz­er” for your body and spir­it. In case of vio­la­tions of bio­log­i­cal rhythms, lemon­grass, ste­via, saf­flower-like leuzea, gink­go bilo­ba and, of course, gin­seng are rec­om­mend­ed.

If all these rec­om­men­da­tions are fol­lowed, your root of life will firm­ly hold you in any, even the most dif­fi­cult sit­u­a­tions.
