人体三节律(国外称PSI三节律)是指人体内自出生之日起存在着以23天为周期的体力强弱期,以28天为周期的情绪波动期,以33天为周期的智力强弱期。对三节律的研究始于本世纪初,国外早有专门研究机构。我国于本世纪80年代初开始研究,并被广泛应用于交通、体育、航空、优生优育等方面。近年来人们逐渐发现人体三节律与疾病发生日存在一定关系,但主要是某些成人疾病。尚未见小儿发病日与三节律是否有关系的报告。为探讨这一问题,我们随机抽取了529例急诊患儿,病种有上感、肺炎、腹泻等儿科常见病。采用双盲试验的调查方法,用电子计算机编制程序,统计分析疾病发生日在人体三节律各期的发生率。结果表明:体力临界期比低潮期和高潮期发生率高,卡方检验均有极显著差异 Three rhythms of the body (PSI trichotomous foreign countries) refers to the body since the date of birth there are 23 days for the period of physical strength period to 28 days for the period of emotional fluctuations to 33 days for the period of intelligence Weak period. The study of the three rhythms began in the beginning of this century, and there are specialized research institutes abroad. China began to study in the early 1980s and is widely used in transportation, sports, aviation, prenatal and postnatal care. In recent years, people gradually discovered that there is a certain relationship between the three rhythms of the human body and the occurrence date of the disease, but mainly some adult diseases. Have not seen the incidence of pediatric day and the rhythm of the report. To explore this issue, we randomly selected 529 cases of emergency children, the disease has a sense of flu, pneumonia, diarrhea and other pediatric common diseases. Using double-blind trial survey method, using computer programming, statistical analysis of the incidence of the disease in the three rhythm of the human body the incidence of each period. The results showed that the critical period of physical strength was higher than that of low tide and high tide, and the chi-square test was significantly different
