Why is a man yawning?
No scientist can unequivocally answer the question: why is a man yawning? In science, there is no exact evidence to prove one or another hypothesis about the reason for yawning and why we sometimes yawn on some days, and rarely on some days.
The process of yawning occurs for unknown physiological reasons. Everyone noticed that if someone yawns nearby, then we certainly want to yawn too. It is also established that people are yawning from the mere mention of a yawn or from reading about it.
Most of the research on the nature of yawning was conducted by Robert Provine, a professor of psychological sciences. He and his collaborators summarized everything that other scientists had ever studied and systematized about yawning.
Yawning is a process that accompanies the human body throughout life. With a yawn, a man opens his mouth wide and exhales the air. In this process, tubes are opened that go from the ear to the throat, which regulates the process in the middle ear, which is associated with pressure.
From this we can conclude that the process of yawning is quite beneficial for the body. In addition, it performs a warning function. Frequent yawning, or vice versa, its absence suggests that the brain may be impaired, the presence of a tumor or bleeding. Similarly, motion sickness and encephalitis can be predicted by analyzing the frequency of a person’s yawning. Many doctors say that mentally ill people get better when they begin to yawn often.
If everything is in order with health, people usually yawn when they want to sleep, when they are bored or they are busy in monotonous business or are watching something uninteresting. If you are interested in work and are alert, then you will not yawn. Often, together with yawning, we indulge. It speaks of mental processes that do not allow these two actions to be separated from each other. I note that animals, when they are yawning, also often stretch. Neurologists claim that the implementation of these two actions at the same time indicates a violation of the brain. But they have no evidence.
Robert Provine hypothesized morning and evening yawning. He came to the conclusion that the evening yawning gives a signal to the brain to relax the body, the morning on the contrary signals the beginning of the day and wakefulness.
In school textbooks, the authors explain the reason for yawning a lack of oxygen in the blood. Scientists have not found a reasonable explanation for this. They also rejected the theory that yawning is associated with high physical exertion. Thanks to the research of scientists, it is proved that a person does not make up for the number of yawns during the day. That is, if he yawns a little, then he will not start yawning more by the evening and vice versa. Therefore, they have no answer to the question: why do people yawn often.
