Sleep and working capacity of a person

Our state of health, mood and activity is changing under the influence of external factors. This is the time of year, and the pressure, and the ecological situation in the place where we live.

However, the working capacity of a person depends on him, on his ability to organize his activities so that it is as effective as possible.

Everyone knows about the art of time management, which allows you to save up to 5 hours a day, without reducing the usual amount of cases. But no time management methods will help, if a person has overstrained and is in a state of extreme fatigue.

Why do we get tired?

The so-called acute fatigue is a normal defensive reaction of the body, which sends the brain signals that resources are at the limit, you need to take a break from work or reduce the load. But if a person repeatedly ignores these warnings, then the state of fatigue can become chronic, which leads to a general decline in efficiency and activity. The extreme expression of fatigue is called overwork, which can already be considered a disease. This condition occurs when a person for a long time is not enough sleep, when his activities are organized incorrectly and there is no time for rest. All this is fraught with the development of somatic diseases, nervous breakdowns, at least. With extreme fatigue, more serious violations can occur.

In order not to bring yourself to extremes, you need to remember that a person's performance and dynamics, in the first place, depends on the time that you allocate for sleep and rest.

Wonderful power of sleep

This is a mysterious process, still not fully understood by scientists. This is the best way to restore all body systems. From the properly organized night rest, first of all depends on the working capacity of a person. Let us consider in more detail what is its usefulness.

When we sleep, our brain continues to function, but only its activity is not at all the same as in a waking state. Based on the analysis of the encephalogram data, five stages of sleep were identified, that is, five forms of brain activity.

The first stage of sleep is a shallow drowsiness, when a person is still on the verge of wakefulness. The more time passes from the moment of falling asleep, the deeper the sleep becomes.

The most important for us are two stages - a deep and fast sleep.

Deep dream

It is called so because during this stage the human body is most inaccessible to the influence of surrounding stimuli. Simply put, a person at this stage is difficult to wake up. The duration of this phase decreases with age, and it is most pronounced in children. There is a hypothesis that during this period favorable conditions are created for the growth and recovery of the body. This phase, most often, occurs 40 minutes after falling asleep. All the processes occurring in the body at this time, dramatically slow down, the person lies motionless and completely relaxed.

Quick sleep

This species is also called paradoxical or sleep with a rapid eye movement. The last name is due to the fact that during this phase the eyes of a person move rapidly for centuries. The paradoxical nature of this stage lies in the characteristics of the encephalogram, which gives a picture similar to the state of wakefulness.

At this stage, we have the most vivid dreams. Being in this phase, people can walk in a dream, talk, make various gestures. It was proved that this phase is "responsible" for the restoration of mental and brain activity. In addition, it is important for getting rid of various diseases. If a person does not sleep for a long time, then, first of all, he lacks this phase.

Human performance depends on how many times in a night the phase of deep and fast sleep has changed each other. That's why it is recommended to sleep at least 7-8 hours.

What is the best time to sleep?

The best time to go to sleep is an individual characteristic, and depends on your preferences. However, in this case there are a number of regularities. So, for example, sleep up to 12 o'clock in the morning causes an increase in working capacity and, what is important for women, helps to maintain beauty.

From the point of view of the peculiarities of diurnal rhythms, the time of maximum decrease in activity and working capacity is the interval from 2 am to 5-6 am. It is this time that is considered the most dangerous, for example, on the roads. Therefore, it is better and healthier at this time to sleep. If this is not possible, then it is necessary to reduce activity as much as possible and give yourself a chance to rest a little.

Human performance is a dynamic characteristic. It does not happen constantly high, at some moments it may decrease. But the main condition of health and activity is a properly organized rest that will prevent fatigue and give you the opportunity to enjoy life in all its manifestations.
