人类进化至今,仍在白天劳作,这就使交感神经活动与新陈代谢的异化占优势。而在夜间,则副交感神经和机体的同化过程占优势。因此,夜间工作会使机体的这种节律性发生紊乱,从而出现食欲不振、失眠多梦、烦躁易怒、注意力分散、思维力迟缓等现象。 Human evolution so far, still working during the day, which makes the sympathetic activity and metabolism of the dominant alienation. In the night, the parasympathetic and the body’s assimilation process prevails. Therefore, night work will make the body disorder of this rhythmic, resulting in loss of appetite, insomnia and more dreams, irritability, distracted attention, mental retardation and so on.
