It is accumulated to overwork that tired
The human body will produce the phenomenon that the ability to work reduces temporarily after sports or certain time of work, called fatigue. It is the protective inhibitory activity on the cerebral cortex that both mental work and physical power is tired, it is a restricted speed signal of cerebral cortex cells, it makes the human body have a rest in time, avoid causing and overworking. People, besides tense working of cerebral cortex while working, a lot of organs work intensely too, especially muscles, so every organ will produce fatigue of a certain degree. Will appear contractile force subside when it is tired for muscle to produce, relax incomplete, carry on chronic sport continuously still when being extremely tired, cardiac muscle and breathe skin, can produce tired too. It is mainly the centre that what the slight work is produced is tired for a long time, this can be overcome by harmless stimulating newly and differently (such as work-break exercises) . Or quiet the intersection of strength and homework produce tired reason, on one hand and the intersection of central nervous system and overstrain transfer to, inhibit, on the other hand it is caused by piling of the supersession product. The medium-sized intensity works for a long time, tired besides centre reason as walking and producing in long distance, the balanced obstacle in water salt is a tired main reason. People it produces tired to be one comprehensive physiological course work, participate in every organ work, will produce fatigue of a certain degree successively, and influence each other, among them fatigue appears at first in the cerebral cortex centre. When being tired generally with the decline of the ability to work, there is a tired sense subjectively, this hints that should quit work and make the body get the signal resumed. People's state of mind acts on in causing and dispelling fatigue greatly, such as fighting and working intensely, people can not sleep but not feel tired with several days; The opposite work is not heavy, but because workers do not have high enthusiasm, there can be obvious tired feelings. " overwork " It is the tired accumulation, people's cerebral cortex function is destroyed at this moment, the unusual change takes place in every organ systematic function state, ability to work and sport achievement obviously drop. Its main reason is not to pay attention to striking a proper balance between work and rest, especially not have enough sleep, ill or recover for convalescence and participate in strong manual labor,etc. too early. Person who overwork early to it displays working sluggishness, sleeps to be good often and appetite fail and giddy unable excitement and working efficiency sleepy easy drop. Further develop, patient's symptom is more obvious, drop insomnia, many sweats, weight, the pulse is accelerated and blood pressure is risen or reduced, even presenting the heart and lungs function, compensating completely, attention laxing, memory drops, accidental injury incident,etc. in the work. The ones that overwork are early can take measures of lightening working intensity, positive rest, lengthening physiological sleep time, supplementary enough nutrition appropriately etc., and the appropriate treatment soon of middle and later periods. People work (work) It produces tired to be a kind of inevitable physiological phenomenon in the course, through the appropriate rest, its ability to work will resume, and can reach ultra quantity to resume. At the request of hygiene of working, arrange work, strike a proper balance between work and rest rationally, guarantee enough rest and sleep, make tired and unlikely to it accumulates to be effective way overworked to prevent from. Meanwhile, essential nutrition supplement is very important too.
