Emotional fatigue refers to people engaged in some monotonous and mechanical work activities for a long time, accompanied by biochemical changes in the muscle, the central local nerve cells due to continuous tension and inhibition, resulting in a significant decrease in enthusiasm and interest in work and life, until the boredom. The main manifestation of emotional fatigue is a change in behavior. Fatigue can be produced in all parts of the body, from the cells of the central cerebral cortex to the basic contractile units of the skeletal muscles. Emotional fatigue should be distinguished from the following diseases: 1. Sports fatigue Sports fatigue (sports fatigue or sport fatigue) is the physiological phenomenon of a temporary decrease in the maximum muscle contraction or maximum output power caused by exercise. The decrease in muscle movement ability is the basic sign and essential characteristic of sports fatigue. Since this century, researchers have conducted a large number of studies on sport fatigue from different perspectives, suggesting that the negative effects of exercise stress metabolic enhancement may be the root cause of sport fatigue occurrence, such as depletion of metabolic substrates, accumulation of metabolites, and acidification of metabolic environment. They may cause changes in the structural integrity of muscle fibers, energy supply, and neurohumoral regulation through a variety of channels, resulting in contractile and diastolic dysfunction of exercising muscles. Therefore, a decrease in exercise capacity, that is, fatigue is the inevitable result. 2, tension fatigue Long-term tension in the state, resulting in the body in a fatigue subhealth state, the serious formation of tension sleep disorder. Tension fatigue, mainly when encountering an emergency, the human body is subject to physiological conditions in response, will produce a large amount of lactic acid, and even the formation of accumulation, once a large accumulation of lactic acid, it will lead to brain nerve stimulation and tension fatigue. 3, neck and shoulder fatigue and soft tissue pain neck and shoulder syndrome due to the work of young people now is a long-term computer and ambulatory work, often keep the head down such a passive position caused by fatigue and soft tissue pain. 4.Auditory fatigue After a period of exposure to strong noise, hearing causes temporary upward shift of hearing threshold, hearing becomes dull, but this situation does not last long, as long as leave the noise place to a quiet place for a period of time, hearing will gradually return to the original state, this phenomenon is called temporary hearing threshold shift, also called auditory fatigue. It is a temporary physiological phenomenon, the inner ear hearing organs are not damaged, and can be restored after rest.
