A busy schedule and low efficiency of working hours are the most likely causes of overwork at work.
Overwork, in contrast to chronic fatigue, is a pathological condition. It develops under the influence of prolonged fatigue, which actually is the main trigger mechanism. But the symptoms of fatigue are not only due to the loss of energy resources of the body, but most as a result of persistent disruption of the central nervous system. The processes of excitation and inhibition of neurons of the brain lose their systematic and periodicity, we can say that the ultra-phase of excessively prolonged inhibition occurs in the cerebral cortex after the excitation phase. In the phase of inhibition, which lasts much longer than the excitation phase, fatigue, inactivity, apathy, delayed and mild reaction in response to stimuli, and in the excitation phase, there are single paradoxical bursts of activity during the periods of morning awakening or evening rest.
The most significant factors in the development of overwork are:
- Insufficiency and inferiority of periods of rest, at the time of fatigue, which reduces the possibility of restoring the efficiency and reserves of the body.
- Continuation of work, overcoming fatigue volitional effort.
- Continuation of work in a state of fatigue with the help of various stimulants - alcohol, coffee, tea, cigarettes, which can bring only a short burst of efficiency through the mobilization of reserves.
Work during fatigue under the influence of strong-willed efforts or stimulants in a desire to increase the efficiency of their working time leads to the opposite result - to the full use of body reserves. And the moment when neither the stimulants nor the efforts of the will will be able to exert the desired effect on working capacity, is considered a transition of chronic fatigue to fatigue.
The total lack of energy reserves in a state of overwork is an extremely dangerous condition for a person, since all the physiological functions of the body are violated. The main symptom that arises in all kinds of overwork is drowsiness. It does not matter how long a person slept - the desire to fall head over to the desktop and fall asleep will haunt him throughout the day. In a state of overwork, a person experiences constant fatigue, headaches. The rate of metabolic processes decreases and immunity decreases. Develops neurasthenia - a person becomes more irritable, he begins to worry about things and situations that he would not have paid attention to before. Develops mental instability, so a person can not stay in a noisy company and other crowded places for a long time. There are symptoms of irritable weakness and sometimes unmotivated aggression.
What measures are needed to prevent such a dangerous condition, as overwork.
First of all, this is accounting for the effectiveness of using working time.
When examining the structure of office workers' working hours using a computer program, DraugiemGroup established:
- The length of a working day does not have a decisive influence on the quantity and quality of the results of labor. It is much more important how the employees organized their working time, that is, how they planned their working day and how they evaluated their working time.
- Those employees who did small but frequent work breaks were more productive than those who worked non-stop for long periods of time
- Computer data processing showed that the most effective way of using working time is to work in cycles of 52 minutes and rest between them for 17 minutes.
- Employees who worked in such a rhythm managed to reach the maximum possible level of concentration and personal effectiveness.
- As fatigue accumulated, they took a short break, during which they completely disconnected from work. After that, they returned to work, full of energy and readiness to work effectively for another hour.
Conclusion - in order not to fall into a state of fatigue and overwork, it is necessary to remember - The human brain needs to rest for 17 minutes after every hour of work!
