Are you an owl or a lark? This is your chronotype, you can not change it ...

You have risen at dawn, are bursting to work, while your second married half is still dead to the world ... Drinking morning coffee falls on your own. But in the evening, when you have already sounded a "retreat!" An hour and then you peck at the nose, you do not understand, and are surprised at your unwillingness to sit at least until midnight. For a long time, the division into owls, who prefer to go to bed late and wake up late, and to the larks, which are already at 5 am "ready for work and defense," determined only the human chronotype in order to represent its potential performance at a certain time of the day.

But the latest studies of European medical professionals make it more likely to look at the seeming absurdity in the desire of one category of the population already at 9:00 pm to "get rid of a dead dream" and another that begins to function actively only after the afternoon. Their results, on the one hand, confirmed the already established belief that everything in the human body is regulated by the internal clock, be it any hormonal reaction or the activation and deactivation of the activity of a certain gene. And on the other hand - a sensation! It turns out that a person feels adequately in a state of prolonged wakefulness due to a single gene, designated Period-3 or Per3. This gene determines which of us is an owl, and who is a lark. It would seem that everything is so simple: there are two variants of the Per3 gene - short and long. In human cells there are two copies of each gene, so for each of us only three variants of a combination of copies are possible - long plus long, short plus short and long plus short. Larks are people with a long version of a gene, owls - with a short one.

Since our biorhythmics is determined by the genetic program, that is, we are inherited predetermined to be an owl or a lark, it is unambiguously clear that you will not pervert or re-educate anyone. The very division of the population into owls and larks in Europe occurred recently - in the 70s of the last century. But then the discrepancy of biorhythms in a married couple was liked to illustrate with a bed picture: the husband is in bed, the wife smacks him on the cheek and says that he will run to the shower for five minutes. Five minutes later she is back, but you can not wake the spouse from the gun - he is a lark, what can you do. In the morning, at five o'clock, an attempt at amorous rehabilitation on his part is doomed to failure, because the wife is an owl, and she does not crucify her before ten o'clock. In general, according to statistics, on our planet about 40% of the total population falls under the definition of "owls", 25% - larks, the rest - the intermediate link, they were called pigeons. They belong to a mixed type, that is, they can be owls and larks. And go to bed pigeons on average at 23 hours. Time to go to bed, in other words - the time of waking up, as well as the beginning of the morning active working day, whether it is at five in the morning or at noon, all this significantly affects our health indicators.

Physicians and sociologists have noticed that the modern rhythm of life is completely adjusted to the larks. One can say with certainty about partial discrimination of owls, for, for example, while they are reeling, most state institutions, banks, polyclinics are already closed, and owls will be late there. Due to the fact that the working day of institutions and enterprises begins in the morning, the "sov" accumulates "nonsense". By the end of the week they are already broken and listless, and their evening activity is not needed by anyone. A tangible threat to the health of owls is caused by evening meals. They eat quite a lot "at night looking," and while packing to sleep with a stuffed stomach, they quickly gain excess weight. A chronic lack of sleep lowers the level of the hormone leptin, which helps to purify the blood of sugar. As a result, researchers note that the owls have fat folds in the neck region.

Let's leave aside the minuses that poison the life of owls, and talk about the larks. It turns out that they are more vulnerable in many respects. The need to adapt owls to larks made them more resistant to stresses, the internal clockwork of owls more adapted to changes than larks. By the way, lark people get tired faster, by the end of the day, when the owl people just got "dispersed", the larks, as they say, "already no". Owls in the evening, when the very peak of show events, is much more energetic and simply more fun than skylarks. But they are at risk of depression. But the owls on the average often change partners and they do not need to beat off a partner from the lark. In love, they are more fun and active ...

Nature "awarded" the innate ability to be an early bird or a night owl. The people have long placed everything on the priorities: "Whoever gets up early, God gives to that", and those who get up late call lazy people, not taking into account that they go to bed after midnight. The life of modern megacities is such that it does not die at night. Leading sociologists say that work on the schedule of larks, as it has developed over the centuries, is nonsense. Current technology allows you to switch to flexible work schedules that take into account the chronotype of each employee. Owls do not lose their self-control in the most critical situations, so they are suitable for the profession of duty operators, emergency workers, firefighters, a number of military specialties. Larks will ensure the awakening of the city and prepare it for a full-time labor or Sunday day. And for couples, one tip: with understanding, take the reality as it is, and be tolerant of the biorhythms of your second married half.
