Objective assessment of workplace stress
To objectify emotional stress in an employee, specialists evaluate a crucial criterion: how heart rate (HR) and respiratory rate relate to the set pace of production activity.
A key characteristic of developing emotional stress is a marked decrease in the correlation between these autonomic parameters and actual work performance metrics. Normally, an employee's functional state depends entirely on how harmoniously intersystem interactions function. The body's homeostatic systems must flexibly match the socially conditioned rhythm of production, but under stress overload, this delicate synchronization collapses.
Prolonged status monitoring
Single episodic measurements of physiological parameters (e.g., standard pre- or post-shift examinations) do not provide a complete picture of the body's condition. The optimal methodology is long-term tracking of human functions directly in real production environments.
Such continuous monitoring serves two main purposes:
- Express diagnostics of the employee's current state.
- Identification of "risk groups," which include individuals with a critically high level of psychoemotional tension.
The immense value of continuous observation is clearly demonstrated by ECG recording. This method allows the detection of dangerous changes that fundamentally cannot be detected at rest. Among such hidden pathologies identified in certain workers during labor are:
- Atrial and ventricular extrasystoles.
- Decreased (depression) of the ST segment.
- Tachycardia attacks and other rhythm disturbances.
Dynamics of tension development and risk groups
First and foremost, specific risk groups are subject to negative impacts. These include newcomers just mastering the labor process, as well as employees with an initially high level of psychoemotional tension.
The pathogenesis of stress-related disorders unfolds in stages:
- Summation of tension occurs (this is especially typical of prolonged, monotonous, or intensive labor).
- Prolonged maintenance of such high tension inevitably leads to resource depletion and functional disorders.
- The final stage is the development of fully-fledged psychosomatic diseases.
That is why a rigorous assessment of the "physiological cost" of production activity is necessary to preserve employee health and ensure proper prevention.
The role of the social environment and biological rhythms
Contrary to assumptions about the decisive role of physical factors (such as microclimate or industrial noise), it is precisely the social environment and the production rhythm it dictates that act as the leading factor. They directly determine the final degree of physiological function strain in the body.
The interrelation between internal biorhythms and the work schedule plays a huge role:
- Optimal activity is observed only when the worker's innate biorhythms fully match the rhythm of the production process.
- Emotional tension rapidly develops in cases of desynchronosis—a severe mismatch between internal physiological clocks and the company's work rhythm.
Briefly: answers to topical questions
Which hormones of the sympathoadrenal system primarily react to emotional stress in workers?
During emotional tension, the sympathoadrenal system is activated, leading to increased secretion of catecholamines.
The main hormones include:
- Adrenaline — causes metabolic and hyperglycemic effects, stimulates cardiac activity, increases systolic pressure only, and provides emergency functional rearrangement.
- Noradrenaline — exerts a generalized vasoconstrictor effect and increases both systolic and diastolic blood pressure.
Which specific physical factors of the production environment can additionally exhaust the worker's body reserves?
Physical factors of the production environment affecting the worker's body include a wide range of microclimate parameters, radiation, and mechanical vibrations.
Classification of physical factors:
- Microclimate parameters — temperature, humidity, air velocity.
- Acoustic vibrations — industrial noise, ultrasound, infrasound.
- Vibration — general and local.
- Optical radiation — laser, infrared, ultraviolet.
- Electromagnetic fields and radiation — static magnetic, electrostatic, and non-ionizing fields.
- Aerosols (dusts) — predominantly fibrogenic action.
- Lighting — natural and artificial.
- Additional factors — atmospheric pressure changes and aeroions.
Class and exam questions
Why are pre- and post-shift examinations insufficient?
Many disorders, such as ventricular extrasystoles or ST segment depression, are consequences of the work load. They manifest only during actual activity and are completely undetectable at rest.
Who falls primarily into the risk group for developing occupational stress?
Risk groups include new employees (beginners in the labor process), as well as individuals who already exhibit an initially high level of psychoemotional tension.
How do biorhythms affect the likelihood of developing work-related stress?
Stress occurs during desynchronosis—a mismatch between human innate internal biorhythms and the external rhythm of production. If biorhythms coincide with the work schedule, activity becomes optimal.
