Have you read Tinkoff magazine? They write about money. They write very fascinatingly. I read it myself. I don't know much about money, and these guys chew everything well. And they write in such a pleasant, understandable style.
So it turned out that they were writing something about health and medicine. And in the same understandable language. But it is very likely that in some places they are a little invented. Immediately I got some kind of sediment.
Well, like, if people in one (familiar to me) region are lying, then it is logical to assume that they are lying in other areas unfamiliar to me, where I will not notice anything, because I do not understand anything there. Somehow it became insulting for them. This journal has traditionally very serious requirements for publications.
The first bell was about the regulation of the relative humidity of the house. using indoor plants.
And here is the second story about stress
I read here they have popular explanations of the "fight or flight" situation, when a person is scared, his heart jumps out, and adrenaline scales.
This activated the sympathetic nervous system. But then one day a person must calm down, and everything comes back to normal.
In general, we have that part of the nervous system that regulates the work of various organs is divided into sympathetic and parasympathetic.
The sympathetic nervous system works according to the "fight or flight" principle, and the parasympathetic nervous system follows the principle of "lie down on the sofa and digest your food."
So, according to the author from that magazine, a person should return to normal by activating the parasympathetic nervous system. Like, when the stress is over, the pulse will be reduced by the parasympathetic nervous system, which slows down our heart. Here, it seems to me, the author is mistaken.
The simplest way to think of a stressful situation is to think of a car with the accelerator pressed. He rushes up the mountain at full steam, hiding from the pursuit. Then the driver calms down, releases his foot from the gas pedal, the car slows down and even rolls back. Moreover, he does not have to include the reverse speed as a parasympathetic nervous system. It is enough just to stop pressing the gazulka, and the car can already roll back.
That is, to slow down the pulse after stress, it is not at all necessary to choke the heart with the parasympathetic nervous system, lie down on the floor and begin to digest food. No. The adrenaline itself will burn out in 20 minutes and the heart rate will drop.
That is, some of us here think that parasympathetic will have to fight sympathy. But this is not the case. Such a struggle within the nervous system can kill a person. We have already analyzed the history of athletes, drowned from diving into icy water. They also had a conflict between the sympathetic and parasympathetic nervous systems.
In fact, such an approach occurs in nature. All these chickens, rats and other possums, numb in an uncomfortable position, which freeze in the face of danger. In this state, they are simply physically unable to move, and predators take them for dead. It is clear that not every predator will disdain the dead. Therefore, the tactic of freezing in a stressful situation is very risky. Well, about the same as the autonomous conflict among runners diving into cold water.
In short, if you escaped from someone and successfully escaped, then the sympathetic nervous system will calm down, and the adrenaline will gradually burn out by itself.
