About diurnal biorhythms

There are two planets:
– How are you?
– It doesn't matter. It looks like I picked up my mind somewhere.
-Nonsense. I've been sick of it once, too. Four, in the worst case, five millennia – and it passes by itself. You will sweat a little if this infection has time to think of a thermonuclear reaction. And if you treat and do not start, then already at the stage of antiquity, remission usually begins. I now take three asteroids a millennium after each ice age for prevention and no problem.

Periods, rhythms, pulsars and pulses – our life, like everything in the universe, is subject to rhythms. Yes, we can take medications or fresh juices for an influx of vitamins according to the time of year. We can take dietary supplements to improve vision or any other system as they are developed, taking into account the circadian rhythm of the need and absorption of vitamins and minerals.  There is no doubt that daily biorhythms affect beauty and health.
I would like to understand, however, the individual characteristics of my own body. Who am I an owl or a lark?
The lark is an early bird, rises high into the sky to meet the first rays of the rising sun. Lark people get up early. They wake up easily, they don't need much time to "wait, I'll wake up now." It is in the morning, before the bulk of the birds of people wake up, they hear their song business tinkering around the house. In the first few hours of the working day, they manage to do much more than in the rest of the working time. In the evening, do not ask the lark to go to a nightclub, spend dinner by candlelight – he is already tired, his eyes are already sticking together, he is already asleep … it is not surprising, because he is already waiting for the morning to cheerfully meet the first rays of the rising sun.
Owls, in contrast to larks, are nocturnal birds. As soon as a blanket of darkness descends on the forest dwellers, owls fly out to hunt. Sleep quietly in your cozy hole, mouse, and don't stick your neck out… Owl people don't like to lie down and don't like to get up. For them, the industry is sophisticated, inventing bulletproof unkillable alarm clocks and alarm clocks that can wake someone up. In this difficult struggle between owls and industry, victory passes from one team to another… In the morning, owls are grumpy, they wake up, they do not want anything, a cup of black coffee or tea can, of course, help, but only when the owl rocks … And generally do not touch the owl in the morning, do not climb to it with your care, do not prevent the owl from waking up. No one can prove to her at all that "whoever gets up early, God gives it to him." She doesn't need your handouts!"
Owls and larks are not the only birds, most people, like most birds, in their diurnal biorhythm are somewhere in the middle between them and the other. I want, of course, to be a pigeon – this is a bird that, according to doctors, flies itself the same way at any time of the day or night. It is a pity that the breed in exact accordance with the definition is difficult to find.
Naturally, the non-coincidence of the biorhythm of the organism and the requirements for it cannot lead to the optimal fulfillment of the task assigned to a person. No, of course, circumstances and the petty officer can make the owl jump out of the bunk, get dressed and stand in line while the match lit by the sergeant burns. Of course, the foreman can send a lark to lay off closer to night (the owls sighed dreamily), but…
Let's not be a petty officer of ourselves and find out when at what hours we feel good and when we have a breakdown. You can find out this in the simplest way – to answer every 2 hours (or every hour) to a question about your well-being. Giving an assessment, let's say in a 7-point scale:

It's time– 3– 2– 10123

you can build a graph. If curiosity takes you far, you will build yourself a schedule of working and weekends, schedules of colleagues and households, and, perhaps, some questions that are not related to the topic of our site will disappear by themselves.
Answering these questions, by the way share the result with us), you will find that not everything is so simple. Well-being is well-being, and physical labor and mental activity do not coincide with it in the optimal hours, and they also do not coincide with each other. When is it better to do gymnastics at home, and when to think fruitfully?
Of course, we are not the first in the history of mankind to think about the issue of maximum activity of different body systems. There are average figures that describe the processes in the body in general, and not in yours in particular.

1 a.m. to 3 p.m.liver
11 p.m. to 1 p.m.gallbladder
7 a.m. to 9 p.m.stomach
1 p.m. to 3 p.m.small intestine
5 a.m. to 7 p.m.large intestine
9 a.m. to 11 a.m.spleen and pancreas
11 a.m. to 1 p.m.heart
7 p.m. to 9 p.m.circulatory organs, genitals
3 a.m. to 5 p.m.lungs
3 p.m. to 5 p.m.bladder
5 p.m. to 7 p.m.Kidneys
9 p.m. to 11 p.m.organs of heat formation

According to doctors, and the information is taken from the www.rususa.com, these figures correspond to an ideal person whose life proceeds in exact accordance with the sundial: he wakes up at dawn and falls asleep at sunset. It is natural to assume that there will be few of them among us, firstly, our real life is subordinated rather not to the presence of the sun in the sky (in vain did we invent electricity?), but to the rhythm of life of the city in which we live, by the way, more than one generation, and secondly, and the sun's appearance in the sky does not track the 8-hour working day, the same and dark winters and bright summers. In addition to the above, my brain is offended, no one told him at what time to work.
We will have to continue this topic when the resentment passes and the time of maximum efficiency comes.
When the resentment passes, we can continue the theme of whether we really want to get a model of our own rhythms, like foucault's pendulum, demonstrating the rotation of the Earth.
