Ramadan fasting and its associated lifestyle changes have been linked to changes in sleep and daytime sleepiness. This study was designed to assess the effects of Ramadan fasting on patterns of sleep and daytime sleepiness.
The SenseWear Pro Armband™ was used to assess the duration and distribution of sleep in eight Muslim and eight non-Muslim volunteers during the last week of Shaaban [baseline (BL) and the first (R1) and second (R2) weeks of Ramadan (1430 H)]. OPTALERT™ was used to assess daytime drowsiness objectively using the John Drowsiness Scale (JDS) to assess sleepiness, and a visual reaction time test was used to assess mean reaction time (MRT).
The mean ages of Muslims and non-Muslims were 36.25 ± 4.46 and 34.75 ± 3.33 years, respectively. Although the start of work was delayed for Muslims from 0730 to 1000 hours, there was no change in working hours for non-Muslims. During Ramadan, bedtime and wake-up time were delayed, and there was a significant reduction in total sleep time for Muslims (5.91 ± 1.36 hours, 4.95 ± 1.46 hours, and 4.78 ± 1.36 hours during BL, R1, and R2, respectively, P < 0.001), but not for non-Muslims. JDS values in both Muslims and non-Muslims were normal at BL (1.70 ± 1.16 and 1.68 ± 1.07, respectively), and no changes occurred during Ramadan (R1 or R2), indicating no increase in daytime sleepiness. There were no significant changes in MRT during R1 and R2 from BL in either group.
Although the sleep cycle of the studied sample shifted during Ramadan among fast observers, there was no objective evidence for increased sleepiness during fasting.
斋月禁食及其相关的生活方式改变与睡眠和日间嗜睡的变化有关。本研究旨在评估斋月禁食对睡眠模式和日间嗜睡的影响。
使用SenseWear Pro Armband™评估八名穆斯林和八名非穆斯林志愿者在沙班月最后一周（基线期[BL]以及斋月的第一周[R1]和第二周[R2]（公元1430年））的睡眠时间和分布情况。使用OPTIONALERT™通过约翰嗜睡量表（JDS）客观评估日间嗜睡情况以评估嗜睡程度，并使用视觉反应时间测试评估平均反应时间（MRT）。
穆斯林和非穆斯林的平均年龄分别为36.25±4.46岁和34.75±3.33岁。尽管穆斯林的上班时间从07:30推迟到了10:00，但非穆斯林的工作时间没有变化。在斋月期间，穆斯林的就寝时间和起床时间推迟，总睡眠时间显著减少（基线期、R1期和R2期分别为5.91±1.36小时、4.95±1.46小时和4.78±1.36小时，P<0.001），而非穆斯林则没有。穆斯林和非穆斯林在基线期的JDS值均正常（分别为1.70±1.16和1.68±1.07），斋月期间（R1或R2）没有变化，表明日间嗜睡没有增加。两组在R1期和R2期相对于基线期的MRT均无显著变化。
尽管在斋月期间，研究样本中的禁食者的睡眠周期发生了变化，但没有客观证据表明禁食期间嗜睡增加。
