摘要: 年轻成年被试在现代人类觉醒期间“标准环境温度”(standard ambient tem-perature)(~20℃)和人体产生和散发热量保持最佳平衡状态的睡眠期间“热中性”(thermal neutrality)环境温度(~30℃)条件下。24-h昼夜测量体(口腔)和皮肤(中背,耳后,肘,手背,足背)温度。皮肤温度借助特制WMSX-01巡回检测温度仅远距离连续测温和自动打印。结果表明;(1)在“标准环境温度”(~20℃)和“热中性”环境温度[~30℃间可见四肢(特别足部)]皮肤温度呈现显著相位性倒转。(2)“非午睡组”和“午睡组”均可见在14:00左右呈现一个体温“钟”的“次要低谷”(Minor nadir),从而表示成年人的体温“钟”也可能具有“半24-h昼夜节律”(Circasemidian rhythm)的内源性特征。

Abstract: Temperature "clock" was measured by 24-h continuous recordings of body(oral)and skin(middle back, postaural, elbow, hand, foot) temperature in 23healthy young adults. Experiments were undertaken under "standard ambienttemperature" (~20℃) and "thermal neutrality" (~30℃) conditions, respec-tively.The former simulated standard temperature condition during wakefulness,whereas the latter simulated the commonly "quilt" ambient temperature duringsleep. Measurements of skin temperature were done by a specially-equippedmultiple thermographic device model WMSY -01,which allowed 24-h automa- tic recordings of 10 different skin positions of the body at a glance. Resultsshowed: (1) Skin temperature of the extremities (especially foot) showed signi-ficant reversal under "thermal neutrality" temperature condition(~30℃)whichsimulated the commomly "quilt" ambient temperature during sleep. (2)A minornadir was observed around 14:00 between 10:00 and 16:00 of the temperature"clock" of both "non-siesta" and "siesta" groups, indicating the possible in-volvement of the secasemidian nature of temperature "clock" in young adultsubjects.
