Although much has appeared in the lay literature regarding the role of biorhythms in life events, few empirical data exist to support the notion that biorhythms affect our lives. The authors first examined the relationship between biorhythms and date of psychiatric hospitalization for 218 patients. They then compared the dates of psychiatric emergency room visits for 386 patients with each patient's biorhythms. The results from both studies failed to reveal a significant relationship between time of psychiatric admission or psychiatric emergency room visit and various phases of the biorhythm cycle. The biorhythm theory is much too simplistic to account for the complexities of everyday life. Therefore, belief in the theory is likely to be an expression of superstitious behavior.
尽管通俗文献中出现了大量关于生物节律在生活事件中的作用的内容，但几乎没有实证数据支持生物节律会影响我们生活这一观点。作者首先研究了218名患者的生物节律与精神科住院日期之间的关系。然后，他们将386名患者的精神科急诊就诊日期与每位患者的生物节律进行了比较。两项研究的结果均未显示精神科入院时间或精神科急诊就诊时间与生物节律周期的各个阶段之间存在显著关系。生物节律理论过于简单，无法解释日常生活的复杂性。因此，对该理论的相信很可能是迷信行为的一种表现。
