There are no owls by nature. Owls exist for the same reason that there are gluttons, smokers, alcoholics, gambling addicts and other slaves of the acquired bad habit.
Reasons: inability to manage time correctly. Another reason is often: hikkanstvo (you don't want to intersect with relatives, if you live in the same apartment, the subconscious mind helpfully suggests not to intersect in waking hours).
This all affects health extremely badly.
You can certainly try to rationalize a bad habit ("you don't understand anything! It's the whole world!"), but it looks just as ridiculous as rationalizing a raw food diet, God forgive me.
I am writing this like an owl with 20 years of experience.
I just want to do my bit. They brought me to kindergarten asleep. There were always problems with being late at school; I chose a job that turned a blind eye to my lateness, but it was easy to stay late or stay overnight. Now it's already 8 years since I found a comfortable time - to go to bed at 7-8 in the morning and get up at 12-13 in the afternoon. But I have one problem - everyone around me is wildly annoyed by it. I want to say that there are not many of us, not half, it seems to me that there are definitely 10-15 percent, and the same number would be happy to live with this schedule (and live longer). And since owls are under constant stress (due to the forced schedule) and do not get enough sleep, they live less. Hence the conclusion - do not try to remake yourself, change the world around you. And you will live in comfort;)
About 32-hour days - the absolute truth. And I think this is the problem with owls. It's just that owls are less able to adapt to a 24-hour day. I judge by myself: I am a typical owl, 8 hours of sleep is not enough for me, I need ten, but if I sleep 10 hours, then I go to bed late at night ... Yes, I can work at least 24 hours a day. But as soon as the artificial social "props" for such a regime are removed, I switch to a 32-hour regime for 3-4 days.
I involuntarily recalled the phrase of one of my former professors: "Larks are those who get up at 5-6. Owls are those who get up at 6-7. And those who get up at 10 in the morning are either students, or housewives. "
I think the concept of larks / owls is greatly exaggerated. They are not born, but become depending on the environment, type of activity, hobbies, partner, having children, etc. Accordingly, people can change over the course of their lives and move from owls to larks, and vice versa. As for working hours, more and more companies are switching not to owl time, but to flexible hours. You need to work 8 hours, and when you do it, it's up to you. I think this trend will spread more and more.
Actually, let's turn to the foundation of the question: why is a person awake in the sunny time of the day, and sleeping in the dark?
What does a person's mode of life depend on at all?
The body is a complex thing though ingeniously simple. One of the parties, which is regulated according to the established program, like instinctive models of behavior, is the mode of life. A person is inevitably connected with the surrounding world, and, thus, dependent on it. What is the basis of life in the "wild" nature? The sun, which feeds some and makes it possible for others to navigate; for the same reason, there is an "anti" -system - nocturnal predators.
Nevertheless, man is not a nocturnal predator. The experiments put by scientists to study the optimal mode of human existence have come to the conclusion that in terrestrial conditions the human body is associated with the solar day cycle, and therefore for a person, whoever he considers himself, no matter how confused his daily routine, the absolute norm is get up with the sun or before it (4-6 o'clock in the morning) and go to bed with its sunset or before sunset (8-10 o'clock in the evening). So, all body systems work harmoniously, because they work "in shifts", and also rest "in shifts". It is this fact that determines the importance of observing the mode of vital activity corresponding to the internal processes of the body.
By the way, in the absence of a light source (the Sun), each subject, independently of others, switched to a mode of 32-hour days.
I could be wrong, but sleep with a 32-hour day lasted an average of 10 hours, while the sleep rate for a 24-hour day is 8 hours.
Because people are very slowly adjusting to all the changes in our being. Fortunately, there are still changes, especially in the tech and creative industries. In many startups today there is not a standardized working day, you can come at 11-12 pm. You can also often work from home.
This is the global inertia of behavior left to us from the industrial society. The working day in factories (and in offices) began at 7-8 am. Accordingly, schools, hospitals, officials, shops and so on were adjusted to this. Now we live in a post-industrial society, and the offices (offices), where most of the people work, can easily work from 11 to 7 or from 12 to 8, but such shifts are happening very slowly. A matter of habit.
Exactly for the same reason as entering the clock to winter / summer time - the combination of the time when people work and when the sun is shining. This was thought to help save candles (and then electricity). Now this is not as relevant as it was a couple of centuries ago, so some companies arrange their working hours so that employees can travel the streets outside rush hour.
Well, and the reason why no one "breaks "tradition and transfers work to the night, it is obvious - it is not profitable. At night and in the evening, most people sit at home and do not think about anything other than rest. Whom to serve?
