Physiological Cost of Work

The physiological cost of work is the amount of expenditure of the body's functional resources necessary to perform a certain type of work. It manifests itself in work stress and functional stress that the body experiences during the labor process.

Work is an activity aimed at achieving certain goals, and it can vary in nature and intensity. For example, physical work, which requires a lot of energy and physical effort, may have a greater physiological cost than intellectual work, which requires more concentration and attention.

The functional stress that people experience during work can manifest itself in the form of fatigue, headaches, muscle tension, etc. This is due to the fact that the body must use its resources to perform work and maintain its functions.

Job stress may also be related to the physiological cost of work. It can manifest itself as increased levels of stress hormones such as cortisol and adrenaline, as well as increased heart rate and blood pressure. All this can lead to poor health and decreased performance.

To reduce the physiological cost of work, it is necessary to take into account the individual characteristics of each person and select work that matches his physical capabilities and mental state. It is also important to provide optimal working conditions, such as adequate lighting, comfortable working conditions, etc., to reduce stress on the body and improve work efficiency.

The physiological cost of work (PCW) is the amount of expenditure of the body's functional reserves that are necessary to perform a specific type of work. This term reflects the fact that the performance of any work is associated with the expenditure of energy and neuropsychic resources. In the case of physical types of labor, these resources manifest themselves in the form of muscular work, and in the case of mental labor - intellectual and emotional.

The functions performed by the body are associated with overcoming various types of resistance. We are talking about external obstacles, interference with movement, changes in body position, the influence of temperature and other environmental conditions. Only a person is capable of not only overcoming resistance, but also using it for his own purposes (changing the vector of traction force and the direction of muscle work). These skills require a person to exert certain efforts on the part of the central nervous system to develop appropriate movements and coordinate the work of certain muscle groups, the nervous system, organs and systems to ensure
