Grief is exhausting

• Central cortical concept of fatigue. The author ( VV Rosenblat ) assumes that the main role in the development of fatigue belongs not to peripheral, but to central processes. Thus, the diverse shifts in the state of the peripheral apparatuses observed during fatigue are secondary and depend on changes in the adjusting influence of the nerve centers. The primary link of the central mechanism has a cortical nature and represents shifts in the cortical apparatus, where the process of inhibition also plays an important role, especially in the cortical link of the motor apparatus. nine0007

The nature of work activity is reflected in the characteristics of fatigue, since functional changes are mainly localized in the links that carry the greatest load. Therefore, depending on the type of work performed, mental and physical fatigue are distinguished, the difference between which is determined by the ratio of the depth of functional changes in individual receptors, parts of the central nervous system, and muscles. Fatigue, which develops during various types of activity, has common features.

Fatigue and performance are closely related. Under certain conditions, the decrease in performance under the influence of work characterizes the degree of fatigue. But at the same time, the relationship between performance and fatigue is also influenced by motivation, the level of activation, and the conditions of the working environment. The manifestation of fatigue is closely related to the phases of current performance, which can be generally characterized as changes in the body's response to the requirements imposed by the nature of the activity. These changes are formed under the influence of the central nervous system, mainly as a result of an increase in the level of functioning of the limbic-reticular system and the vegetative part of the nervous system and the endocrine system regulated by it, which leads to an increase in current performance due to an increase in the intensity of the activity of all parts of the functional system. As functional reserves decrease, fatigue develops, which is a system of containment from excessive costs. To implement the volitional effort that compensates for fatigue, there is an additional inclusion in the work of nerve centers and synergistic muscles, and as a result of this, the activation of physiological mechanisms for enhancing the activity of the autonomic parts of the nervous and hormonal systems that provide activation processes in humans. nine0007

Fatigue is a biologically expedient process, which, on the one hand, signals the need to stop work, and on the other, is a necessary condition for increasing the fitness of the body.

• Fatigue criteria. According to subjective assessment fatigue of the organism is a special, peculiarly experienced mental state, called fatigue and having several components: weakness, manifested in the impossibility to continue work of the required intensity; attention disorder; violations in the motor sphere, affecting the slowing down or erratic haste of movements; deterioration of memory, thinking; weakening of the will; drowsiness, etc. Subjective manifestations reflect the state of objective processes in the consciousness or sensations of the person himself. Nevertheless, subjective assessments of fatigue depend on motivation, interest in the work performed, the level of claims and the degree of responsibility in performing the task, and the complexity of the activity performed. nine0007

objective criteria of fatigue include two groups of assessments:

– changes in work efficiency;

- changes in various physiological systems that accompany the development of fatigue.

Fatigue leads to the strain of performing those operations that require maximum mobilization of attention. Prolonged exercise, leading to fatigue, causes certain shifts in the frequency structure of various physiological functions. The common thing is the slowdown of the rhythmic processes occurring in the body - heart rate, surface electromyogram of the muscles of the diaphragm, etc.

Overwork. Many types of mental work are characterized by small changes in the functions of the body and current working capacity during the day, that is, the formal absence of pronounced fatigue. Despite this, dynamic studies (conducted over a month, a year) show a constant accumulation of adverse changes that also affect performance. Such shifts are referred to as chronic fatigue, described in schoolchildren, students, operators, etc. , whose work is characterized by high, prolonged neuro-emotional stress or its combination with the influence of other adverse factors. Chronic fatigue is possible only with the accumulation of adverse changes, when the recovery processes are insufficient for the complete normalization of body functions and its performance. Therefore, as a rule, chronic fatigue is overwork. nine0007

• Overwork criterion – Work-induced decrease in performance that does not resolve during a post-work rest period. The reasons for the cumulation of adverse functional changes can be divided into several categories. First of all, this is high stress in the process of work, caused directly by the labor process or its combination with the influence of adverse factors in the working environment, low health, and chronic diseases. Of great importance is the lack of recovery processes after work, associated with errors in the regime of the day and life in general - insufficient duration and quality of sleep, low physical activity, malnutrition, workload at home, conflict situations. With chronic fatigue, functional disorders are manifested - asthenovegetative syndrome, vegetovascular dystonia, deterioration in the functions of the central nervous system. The cumulation of fatigue has an adverse effect on the body, contributing to the emergence of a number of general diseases or exacerbation of chronic ones. Overstrain and overwork also develop with an unfavorable combination of intensity and duration of work. nine0007

• Prevention of overwork should be closely linked with measures to ensure high work efficiency, not leading to overwork and overwork. According to the nature of this or that type of fatigue, various methods of its removal are also appropriate. So, for acute fatigue is the very cessation of current activity and normal sleep, for chronic it is a change in the regime of the day and rest, a general decrease in workload, an increase in motivation and positive emotions, more or less long rest with the cessation of professional activity and filling leisure activities complementary and diverse in content forms of activity. nine0007

In general, measures to prevent overwork can be divided into several groups:

1) measures aimed at increasing the true, maximum, but not leading to overstrain performance - rational training and adaptation to working conditions in general, and under more difficult circumstances - readaptation after a long break in work;

2) measures to preserve and promote health, including a rational daily routine, balanced nutrition, rejection of bad habits, timely treatment of diseases; nine0007

3) periodic preventive examinations;

4) selection for professions that make high demands on the body of the worker;

5) optimization of the working environment, taking into account ergonomic requirements;

6) means of stimulating recovery processes, which include an increase in the duration of rest, walks, physical therapy and other therapeutic and prophylactic procedures, the use of pharmacological agents.

Hadith: “Whatever befalls a Muslim, be it fatigue, illness, sadness, resentment, sorrow, and even a thorn on which he pricked, Allah will certainly make it an atonement for some of his sins.

Hadith: “Whatever befalls a Muslim, whether it be fatigue, illness, sadness, resentment, grief, and even a thorn on which he pricked, Allah will certainly make it an atonement for some of his sins.” nine0007

Abu Sa'eed al-Khudri and Abu Hurayrah (may Allah be pleased with them both) reported that the Prophet (peace and blessings of Allah be upon him) said: sorrow, and even the thorn on which he pricked, Allah will certainly make it an atonement for some of his sins.
Valid. - Agreed upon by Al-Bukhari and Muslim

Explanation

The meaning of the hadith is this: illnesses, anxieties, sorrows, troubles, difficulties, fear and shocks that befall a Muslim become an atonement for his sins, erasing them. If a person adds to this patience and hope for a reward from Allah, then he will also receive a reward. When a person experiences a test, two scenarios are possible. First, the tested person remembers the reward and the hope of obtaining this reward from Allah. He receives a double benefit: atonement for sins and an increase in good deeds. Second: a person does not remember this, and his chest is shy, he begins to grumble or something similar happens to him, and he does not have the intention to patiently endure this test in the hope of receiving a reward from Allah. Then the test becomes only an atonement for his sins. Thus, he wins in any case: either the expiation of sins without receiving a reward, because he had no corresponding intention and he did not show patience and did not hope for a reward from Allah; or both the atonement of sins, and the reward from the Almighty and Great Allah. Therefore, when something unpleasant befalls a person, even a prick of a thorn, he should remember the hope for a reward from Allah, so that he will receive a reward along with the expiation of sins. This refers to the manifestations of Allah's mercy, His generosity and generosity: He puts the believer to the test, and then rewards him for this or forgives his sins. An important note: minor sins are forgiven a person. As for serious sins, sincere repentance is necessary for their forgiveness. nine0007

Benefit

1. Sickness and other troubles are trials that come upon the believer. They cleanse him of sins, even if they are few.
2. Great good news to Muslims: there is no Muslim who would not be comprehended by such trials. nine0005
3. Raising degrees through these things and increasing the good deeds recorded by a person.
nine0025 Forgiveness of sins extends only to some sins, in particular small ones, but as for grave ones, repentance is necessary for their forgiveness.
