我们假设，除了饮食习惯的突然转变之外，还有其他因素导致了斋月期间昼夜节律的延迟。我们使用便携式臂带生理和活动传感器设备评估了6名健康的穆斯林年轻人在斋月基线期（BL，斋月前1周）、斋月第一周（R1）和第二周（R2）的昼夜节律变化。所有参与者都生活在一个不受约束的环境中，并表现出睡眠阶段延迟综合症，因此他们通常白天睡觉，晚上吃饭。在斋月期间，皮肤温度的顶相进一步延迟，表明体温的昼夜节律模式发生了变化。此外，能量消耗峰值在R1和R2期间有延迟。这些结果支持了我们的假设，即除了吃饭时间的突然改变，其他因素可能会影响斋月期间的睡眠模式和昼夜节律。(C) 2010 Elsevier Ltd.版权所有。
We hypothesize that factors other than a sudden shift in eating habits contribute to delay of circadian rhythms during Ramadan. We assessed circadian changes during a baseline period (BL, 1 week before Ramadan), the first week (R1), and the second week (R2), of Ramadan, in six healthy Muslim young adults using portable armband physiological and activity sensor devices. All participants lived in an unconstrained environment and showed delayed sleep phase syndrome, so that they normally slept during the day and ate at night. During Ramadan, there was a further delay in the acrophase of skin temperature during Ramadan, indicating a shift in the circadian pattern of body temperature. Additionally, there was a delay in the peak of energy expenditure during R1 and R2. These results support our hypothesis that in addition to sudden shift in meal times, other factors may affect the sleep pattern and circadian rhythms during Ramadan. (C) 2010 Elsevier Ltd.
