Continuous recordings of rectal temperature were made from 40 normal infants, aged 3-4 months, at home during two days of normal activities. We found that the rectal temperature of a normal, healthy baby may vary from 36.0 degrees C at night to 37.8 degrees C during active periods of the day. During daytime sleep rectal temperature fell, but to a lesser extent, and for less time than during night time sleeps. Feeds raised the temperature unless the baby slept, when they reduced the rate of fall of temperature. Bottle feeds affected temperature more quickly than breast feeds. The changes in temperature during sleep and after feeds were independent of the room temperature or thermal insulation of clothing and wrapping.
对40名3至4个月大的正常婴儿在正常活动的两天里在家中进行直肠温度的连续记录。我们发现，正常健康婴儿的直肠温度可能在夜间低至36.0摄氏度，而在白天的活跃时段高达37.8摄氏度。白天睡觉时直肠温度会下降，但降幅较小，且下降时间比夜间睡眠时短。喂奶会使体温升高，除非婴儿在睡觉时喂奶，此时喂奶会减缓体温下降速度。奶瓶喂养比母乳喂养对体温的影响更快。睡眠期间和喂奶后的体温变化与室温或衣物及包裹的保暖程度无关。
