本文通过对2289例新生儿出生时间昼夜节律的分析,发现阳气上升的下半夜、上午与阳气旺盛的中午新生儿出生数较多,而阳气衰落和最弱的下午、上半夜则较少。初步证实新生儿出生的昼夜节律与中医基础理论中关于阳气运行学说相一致。符合《素问·生气通天论篇》的理论:“阳气者,一日而主外,平旦人气生,日中而阳气隆日,西而阳气已虚,气门乃闭”。 By analyzing the circadian rhythm of 2289 newborns at birth, we found that in the middle of the night when the yang rose, the number of newborn babies born at noon in the morning and yang yang was higher, while that of the weakest yang and the weakest afternoon at the middle of the evening less. The preliminary confirmation of the circadian rhythm of newborn birth is consistent with the doctrine of yang running in the basic theory of traditional Chinese medicine. In line with “Su asked angry theory” of the theory: “yang who, one day and the Lord, Ping Dan popular life, Japan and China Yang Long day, west and yang is empty, the valve is closed.”
