Biological clock: what you need to know?

Sometimes the most obvious things is hiding the truth: everyone is different. However, the modern pace of life just seems to be blind. Kindergartens, schools, banks, hospitals and almost all organizations in the world begin training and work day at the crack of dawn. An early rise is considered to be infallible truth, the iron rule, and I would even say a cult. Try to tell somebody that get up at two in the afternoon as you will instantly be labeled as a lazy parasite. All attempts to explain that early rise equivalent to the fact that you moved the truck, doomed to failure. However, this is not a reason to be upset. The fact that all living organisms on our planet have built-in biological clock – circadian rhythms – which determine when we go to bed, what time I Wake up when I want to eat, run and so on. This means that if you get up early and feel great in the morning, or Vice versa, due to the early rise instantly nauseated, it's not a whim or laziness – that is, how does your body. It is important to understand that any attempt to modify the built-in biological clock can result in health problems. In this article, you will learn who are the pigeons, owls, larks, and why we, as a society, it is time to reconsider its attitude to the daily routine on the basis of the results of scientific research.

In fact, it is the product of interaction between internal biological clock of the organism and the environment, because in addition to sunlight, a number of factors determines the behavior, regulates body temperature, sleep, hormone levels and metabolism.

What is a chronotype?

The Study of circadian rhythms of all living creatures on Earth are engaged in chronobiology. the Chronobiology is the science that studies the conditions of occurrence, the nature, patterns and significance of circadian rhythms and the relationship between biorhythms and human health. Note that this is a young area of interdisciplinary research, which is in the process of its formation.What chronobiology introduced the concept of the chronotype, the nature of daily human activity. the Chronotype reflect the daily dynamics of functional activity of different organs and systems of the body. Thus, depending on the activity at any given time of the day scientists have identified three chronotype


  • Larks — morning type
  • the
  • Pigeons — day type
  • the
  • Owl — evening type

    It is Important to understand that the differences between chronotype it's not just the tendency to early or late awakenings. Although, of course, most people on the planet without too much difficulty and harm to health readjust to the morning or evening rhythm for a couple hours (pigeons). In fact, each chronotype characterized by specific features of life which develop resistance to certain factors and the strong sensitivity to others. That's why owls, unlike the lark, it is so hard to get up in the morning. But that's not the only reason. The fact that the unique behaviors of every living being encoded in the genes, besides the previously scientists have determined that the «clock gene» or «gene period», which is responsible for the circadian rhythms. It means that the clock gene contribuire blood pressure, metabolism, hormone levels and circadian rhythms work. Moreover, revealed a relationship between the required amount of sleep and length of the gene period.

    And you hear the alarm clock in the morning?

    However, the results of the latest research, published in the journal , showed that chronotype (belonging to early risers and owls) only partially depends on the genome. In the study, experts analyzed data on the human genome and almost 700 thousand people, provided two bases of genetic data – service genetic testing and British programs . In fact, genes «included» or «off» because of environmental changes. Read more about this and also about how genes associated with sexual orientation .

    After Analyzing and comparing genetic data, scientists have identified more than 350 variations of genes that are somehow associated with belonging to a particular chronotype – the owl or lark. Moreover, it was found that larks go to bed by as much as 25 minutes earlier (on average) than people with the fewest genetic variations. Even more interesting was the relationship between chronotype and health (physical and mental). So, depression and schizophrenia more common in owls, which is not surprising as in the past, a number of studies have linked the risk of diabetes, obesity and mental disorders with «the owl chronotype». It is important to note that despite the correlation, strong «skew» in the direction of early or late awakening among subjects with depression and schizophrenia was not observed.

    Early is harmful to health?

    Let's stipulate at once – if you are an early bird, regular sleep, get up at 7am and ready to move mountains – you have nothing to worry about. But the rest is clearly to treat its mode carefully. Five years ago, Paul Kelly of the Institute for sleep and circadian neurobiology, University of Oxford equated working day from 09:00 to 17:00 for the torture. This Professor said during a speech at the British festival of science .

    In practice, this means that the company, in which the working day starts with the first rays of the Sun, likely to cause harm to themselves, simultaneously increasing the risk of disease among employees. The same applies to schools and hospitals as lessons and procedures is usually carried out before 9 am.

    the working day should not begin before 10 am. the Adult can work from 9 am only after 55 years. Look closely at our society, it is suffering from sleep deprivation. To change their biological rhythms we can't. the you can't accustom the body to get up at a certain time. Our heart and liver work according to your schedule, and we ask them to pick up and move for a few hours. The most common form of civilized torture is up early and start the day until 10:00 am.

    Paul Kelly – lead author of the study.

    This is a problem for people all over the world. You know how many hospitals Breakfast? But this is the real torture is when you're not hungry. Besides, due to lack of sleep people become obedient and worse to think. So whatever your chronotype, if you sleep less than six hours during the week, there will be changes at the level of genes. Lack of sleep negatively affects performance, memory, attention, etc. But that is if every day to sleep in I .

    Where did the 8-hour day?

    So, we found that early rise may have a negative impact on health, and coupled with a regular lack of sleep increases the risk of developing problems. But where did the eight-hour day, which should begin in the morning? In fact, the reason most of us work from 09:00 to 17:00 has science nothing. the thing is that in the early twentieth century, the eight-hour day enabled the entrepreneurs to effectively manage the factories. One of the first companies that allowed employees to work 10 hours and 8 company was the Ford Motors in the United States. The success of the new schedule of work has inspired other companies. Here's how to create a modern working week.

    Perhaps the reason your colleague is late all the time is hidden in its genes.

    But with the advent of the Internet, and also with scientific-technical progress of humanity can (and should) change the number of hours that people spend in the workplace, and forbidding to start work and training the day before 10 am. And it must be done in the first place because the employees who get enough sleep and spend less time at work, more productive work. Whether we like it or not, but a revision of current models of work injury or later it will happen. In addition, in the future there will be work that will do more work, significantly freeing up time for us. This statement several years ago made during a meeting of the national governors Association of the United States in 2017.

    Why your personal experience means nothing?

    We all to a greater or lesser extent, accustomed to rely on their own experience. This is useful in many cases, however, it is important to understand that your personal experience is not objective truth. what you have experienced personally and those things that you think are acceptable to you, but that doesn't mean that the way things really are. If you to easily get up in the morning, and your friend, relative or colleague each morning, reminiscent of the zombies and badly understands, that does not mean that he is lazy and spent the whole night watching TV shows (though this also occurs, of course). But in most cases the person is not to blame for the fact that his biological clock works that way. Similarly, do not expect avid lark transition to nocturnal – sooner or later, biology will prevail and people will return to the usual schedule, oblukovina work circadian rhythms.

    However, the fact that personal experience is subjective does not mean that we should not hide your chronotype and share the lifestyle. Do not forget that we are all very different and each body needs. For this article we decided to share with you their stories and tell which of us is the owl, the lark, and even a pigeon. Let's start traditionally, with the lark:

    I consider myself to lark — used to Wake up at 5-6 o'clock in the morning, sometimes I managed to get to the gym and then to work. The sport was greatly facilitated by earlier awakening, but sometimes the body is asked to sleep some more —then immediately went to the office. For me morning — the most productive part of the day; the same work that night I'm going to do 3 hours in the morning I can do in 1.5 hours. The only negative — we must go to no later than 22 hours. Now the work hours have changed and go to bed later, so sleep longer. But the daily routine in relation to sleep I have not changed — in the morning I work easily. And in my field it is useful to quickly explore what happened from their colleagues in the West (it was day) while we slept.

    Alexander Bogdanov (Moscow, Russia), author

    A lark consider yourself editor Renat Grishin, although most of his life was convinced that he is a real owl.

    The Last few years I became an active morning person. My day starts around 7 am regardless of what time I went. And I always considered myself a night owl. To go to 2-3 nights and Wake up around noon for me was the norm. But now everything has changed. The morning hours are the most productive. While everyone is asleep in the morning, I can quietly to work. Day and night no longer work. Family are constantly requires attention and mustache isolation nowhere to hide from that, I can't. And if earlier I considered that waking early is almost impossible for me, but now my opinion has changed kordinalno. I — a lark!

    Renat Grishin (Moscow, Russia), editor

    However, as practice shows, the owls still more than larks, at least at us in edition:

    I'm a night owl, I find it easier to work at night, when colleagues and employees are already asleep. Peace and tranquility comes more ideas and better performance. So the body has chosen this mode. Although I understand that getting up early is effective and useful for health.

    Michael Korolev (Barcelona, Spain), owner

    Pavel Dmitriev, which regularly makes a fascinating related audio updates on our website, left a comment here:

    I'm a night owl, I have to 23-00 almost the peak of productivity occurs. This morning I have to sleep longer just. I tried to go to sleep early, but still get that matters, not the number of hours of sleep, namely the Wake-up time.

    Paul Dmitiev (Bar, Montenegro), author

    I'm a pure night owl. Perhaps due to the fact that just the night love. I love to ride a bike on the night highway, or simply walk through the city. Wake up in the morning is almost always difficult, but if necessary I can sleep three hours awake. The main thing to clear up. If cleared, it is already much easier.

    Artem Sutyagin (Korolev, Russia), author

    As you can see, we are all really different and everyone has a certain schedule that he adheres to and where he's comfortable.

    So for me, as I can remember the early climbs had taken a toll. In the future I realized myself not to change and have completely revised my life. Quit my job, which had to come to 9am (and it still did not work) and gradually bring your schedule back to normal. For me the norm is to fall asleep about four in the morning and I get up around 12:00-13:00. In this chart I feel great, sleep and most importantly eat Breakfast in the morning. This may seem surprising, but early awakening completely fought off my hunger. Now I understand that this is due to circadian rhythms, so most of my life I just wasn't able to eat Breakfast. But it was enough to listen to your body, how the situation has changed for the better.

    To summarize I want to say that situations in life happen different and not always can be so easy to take and change work, study and so on. However, it is important to understand that when we are young, the body can withstand a lot, but resources are not infinite. This is similar to the fuel consumption: we spend too much energy to adjust the mode to the generally accepted pace of life, but it will lead to problems with circadian rhythms in the future. So let's pay attention to each other and especially to ourselves. Be well.
