摘要:
Daily periodic changes of body temperature were examined in 138 subjects ranging in age between 5 days and 44 years. Whereas the circadian rhythm of human body temperature was not discerned in newborn babies, body temperatures were higher during daytime than during nighttime in infants over one month. Temperature rhythm similar to that of adults, with respect to phase, was observed in the age groups of ten to eleven months and over, earlier than previously reported. The amplitude in circadian oscillation was, however, significantly larger in children between 7 months and 7 years of age than in adults. Thus, it is concluded that the adult type of circadian rhythm of human body temperature is fully established with respect to phase and amplitude after 7 years of age.
