摘要

人类有昼夜节律,其周期因个体而异。在本研究中,我们研究了在昏暗的光线下度过一天后(第1天至第2天)昼夜节律的自然相位延迟量,以及第二天早上(第2天至第3天)由于光照(8000 lx,4100 K)而导致的相位提前量。还研究了相移与昼夜节律、时间类型和睡眠习惯的关系。研究了昏暗褪黑激素发作(DLMO)作为每天的昼夜节律相位标志。在用于分析的27名个体中,从第1天到第2天,DLMO显著延迟(-0.24±0.33小时,p<0.01),从第2天到第3天,DLMO显著提前(0.18±0.36小时,p<0.05)。相移之间存在显著相关性,在昏暗环境中相位延迟较大的受试者在光照下相位提前较大(r=-0.43,p<0.05)。然而,与昼夜节律、时间类型或睡眠习惯没有显著相关性。这些相移可能反映了相位的稳定性,但不考虑个人的时间类型相关指标。

Humans have a circadian rhythm for which the period varies among individuals. In the present study, we investigated the amount of natural phase delay of circadian rhythms after spending a day under dim light (Day 1 to Day 2) and the amount of phase advance due to light exposure (8000 lx, 4100 K) the following morning (Day 2 to Day 3). The relationships of the phase shifts with the circadian phase, chronotype and sleep habits were also investigated. Dim light melatonin onset (DLMO) was investigated as a circadian phase marker on each day. In the 27 individuals used for the analysis, DLMO was delayed significantly (-0.24 ± 0.33 h, p < 0.01) from Day 1 to Day 2 and DLMO was advanced significantly (0.18 ± 0.36 h, p < 0.05) from Day 2 to Day 3. There was a significant correlation between phase shifts, with subjects who had a greater phase delay in the dim environment having a greater phase advance by light exposure (r = -0.43, p < 0.05). However, no significant correlations with circadian phase, chronotype or sleep habits were found. These phase shifts may reflect the stability of the phase, but do not account for an individual's chronotype-related indicators.
