According to the popular biorhythm model accidents are more likely to occur during the “critical days” of three sine wave-like cycles that display periodicities of 23 days, 28 days, and 33 days. Analyses of 400 mining accidents from two separate industries demonstrated that the number of employees who were involved with accidents on their individual critical days of the different cycles did not differ significantly from chance expectancy. Furthermore the number of employees involved in…

Biorhythms and the incidence of industrial accidents
Biorhythm critical days have been suggested as a possible cause of industrial accidents by a number of authors, although the empirical evidence is confusing. This study examined all industry-related
Comprehensive Review of Biorhythm Theory

TLDR
This paper reviews 134 studies of biorhythm theory, both published and unpublished, and concludes that biorHythm theory is not valid.
Critical Analysis of Biorhythms and Their Effect on Industrial Accidents in Agra Casting Manufacturing Units
TLDR
The study concluded that biorhythm theory has a strong basis to justify its application to strenuous work in casting manufacturing units and acts as an information system in predicting the accident occurrence.
Investigation of biorhythms in female athletic performance.
TLDR
This study assessed the validity of biorhythms by analysing best performances in 610 top ranked European female track and field specialists over a single competitive season and found no significant influence of the computed physical, emotional or intellectual cycles on peak performances.
The effect of biological rhythms and personality traits on the incidence of unsafe behaviors among bus drivers in Shiraz, Iran
TLDR
Taking the measures including selection of low-risk traffic routes in the critical days and considering the personality traits at the time of employment could be effective in reducing the unsafe behaviors and accidents.
Snow fall and heart attacks.
TLDR
It is concluded that the occurrence of heart attacks is independent of snowfall but that, when they occur, they are attributed to shoveling if there has been a recent major snow storm.
The human factor in driving accidents. An overview of approaches and problems.
TLDR
Several approaches to accident involvement are considered and an attempt is made to concentrate on the major issues with particular emphasis on the conceptual difficulties which each approach faces.
