Specific perception during stress is due to the fact that the body is working in difficult conditions. Biochemical processes in it at this time are very intense, external destructive influences inhibit the activity of the nervous system, and the body reacts to this very sharply.
Instructions
Step 1
To understand what happens to the human body and psyche during stress, you need to determine what this stress is and how it happens. Stress is called destructive biochemical processes that are formed in the human body under the influence of all kinds of unusual factors. These factors themselves can be very different, positive and negative. The appearance of positive stress factors also somewhat disrupts the normal functioning of the body, but such stress is often called useful, since it tones up the body and stimulates its activity. But negative stress factors lead to psychophysiological changes, sometimes quite serious.
Step 2
Stress is a very difficult time when a person needs, first of all, to survive: this is how nature looks at this process. For this reason, under the influence of stress, people first produce adrenaline. In reality, this happens more often than it seems, as life is filled with stress. Problems begin when a person ceases to cope with these challenges, and the body is tired of eternal stress.
Step 3
During stress, adrenaline activates the nervous system, which initiates a further biological scenario called "stress". Its main consequence is the body's attempt to strain all the organs of perception as much as possible. The pupils become dilated to process as much of the incoming information as possible. Attention increases, since any little thing can indicate a worsening of the situation and the need for a quick reaction. Hearing is getting better. The nose senses all the smells. For the same reason, perception becomes sharper, a person at the biochemical level in all possible ways captures information about what is happening and how to cope with the situation. But for a modern person in a state of stress, all these clearly manifested details are usually only annoying. Nervous tension and increased sensitivity often lead to the fact that stress only intensifies.
Step 4
In addition to the organs of perception, the changes also concern other functional characteristics of the organism. Muscles are straining, since, according to the body, all the forces need to be thrown into keeping the most important thing in an active state. The activity of important self-regulation mechanisms is suppressed. The immune system starts to work worse, the number of leukocytes in the blood falls. It would seem, why is this happening, because during stress, people need the exact opposite? The reason is that stress over the course of thousands of years of human evolution has been of only one type: danger from which you can escape. Whether it's a wild animal, a natural disaster, an unsuccessful hunt or an aggressive member of your species: any stress in this group can be dealt with by moving your legs very quickly.
Step 5
An active social life appeared in human individuals not so long ago. Evolutionists argue that the human species developed such a rapid development thanks to social relations, which forced the brain to develop very quickly. Evolutionary mechanisms, which appeared long before the socialization of living beings, sometimes give a slightly strange effect in relation to people, since a person's way of life is far from natural.
