Biorhythm or biorhythm management can be considered as one of the new areas of management that has received special attention after ۱۹۸۰. In the management of biorhythm or biorhythm, the goal is to analyze and investigate the four main human cycles, i.e. body, emotion, thought and intuition, which are repeated in specific time intervals and in ۲۳, ۲۸, ۳۳ and ۴۰ days respectively in a positive state and or it is negative. In the current research, with regard to this concept, in two organizations with productions and foundry processes, biorhythm management was implemented and its relationship with occupational accidents was analyzed. The results have shown that nearly ۷۵% of occupational accidents are directly related to life cycles, and among these cycles, the physical cycle plays the largest role in the occurrence of occupational accidents with ۵۰%. Meanwhile, intuition cycle has no significant relationship with occupational accidents.
