The state of fatigue associated with the performance of labor duties, very often arises as a result of insufficient clear planning of the working day or with various voluntary and involuntary deviations from a well-designed plan. Fatigue leads to a decrease in productivity.
An employee who does not take into account the need to constantly take into account the effectiveness of working hours, loses him for various reasons, both external and internal, during the working day, and then trying to catch up, starts to work at an accelerated pace, which leads to a rapid fatigue.
then the state is characterized by certain indicators:
- difficulty concentrating on the required task,
- fast fatigue,
- the inability to "get involved" quickly,
- the difficulty in estimating time costs for this task,
- falling attention activity,
- memory loosening,
- slowness in decision-making,
- violation of the clarity of logical constructs in solving the problem,
- a violation of the ability to abstract thinking,
- difficulties in forming conclusions and judgments.
In addition to reducing the ability to focus on the quality of the task, fatigue, often associated with fuzzy working day planning, has external physical signs. An employee often changes his position at the desk, supports his head with his hands, or periodically bends her on the table, stretches out on a chair, leaning back against his back; there is a violation of the rate of speech and a smoothness of mimic reactions; movements become slow and uncertain, fussiness and tension in the fingers appears, which leads to distortion of the handwriting and slowing down the speed of the keyboard.
The subjective sensations of fatigue associated with a not very critical assessment of the effectiveness of working time are expressed in the following symptoms: general discomfort, headache of varying intensity, pain and tension in the legs and arms, lethargy, apathy, drowsiness, irritability, quick temper, indifference , decreased mood.
In addition to these purely subjective symptoms of fatigue, there are also objective signs: a decrease or increase in blood pressure, a rapid heartbeat, changes in the ECG, systolic murmur, arrhythmia, various changes in the blood count, an increase in the frequency of respiratory movements.
Fatigue should be perceived as an integral physiological state of the body under various loads, both physical and mental. The manifestation of this condition depends on the degree of fatigue, and the degree to how much one can effectively use their working time. Mild fatigue has a positive quality - it has a beneficial effect on the body, making use of reserves.
But at the same time it is a signal to stop work, to take a break or to reduce the intensity. But if a break in activity does not relieve fatigue, it means only one thing: it is necessary to work out more rational forms of labor activity, that is, to revise one's attitude toward the effectiveness of using working time. Preventing fast-onset fatigue is a clear working day plan, and a daily analysis of the use of working time.
In addition to loss of productivity, fatigue requires much more time to restore energy resources than simple fatigue after a day's work. Already it is not enough just to have a good rest and sleep, fatigue can take a chronic form and often, in order to recover, the employee has a need to arrange a break for two to three days, and sometimes for a longer period. Strong fatigue has a negative effect on the body, as there is a complete depletion of the body's energy resources, which can lead to the development of fatigue.
