摘要

环境、社会和行为变量影响睡眠时间和持续时间。使用腕带加速度计,我们记录了31名舞者(年龄= 22.6±3.5),为期17天,他们在早上(n = 15)或深夜(n = 16)训练。我们估计了舞者每天的睡眠模式:开始、结束和持续时间。此外,还计算了他们每天的中高强度身体活动分钟数(MVPA)和平均照度,并计算了早班和晚班时间窗口。在训练日,这些变化涉及睡眠时间、闹钟驱动的唤醒频率、光照模式和MVPA持续时间的差异。当舞者在早晨训练和使用闹钟时,睡眠会大大提前,而晨光对睡眠的影响较小。当舞者在深夜更多地暴露在光线下并表现出更长的MVPA时,睡眠就会推迟。在周末和使用闹钟时,睡眠时间明显缩短。当早晨照度较低或深夜MVPA较长时,也观察到睡眠时间的小幅减少。轮班训练影响了环境和行为因素的时间,这些因素加起来塑造了舞者的睡眠时间和持续时间。

The Influence of Light and Physical Activity on the Timing and Duration of Sleep: Insights from a Natural Model of Dance Training in Shifts.

Environmental, social, and behavioral variables influence sleep timing and duration. Using wrist-worn accelerometers, we recorded 31 dancers (age = 22.6 ± 3.5) for 17 days and who trained either in the morning (n = 15) or in the late evening (n = 16). We estimated the dancers' daily sleep pattern: onset, end, and duration. In addition, their minutes of moderate-to-vigorous physical activity (MVPA) and mean light illuminance were also calculated daily and for the morning-shift and late-evening-shift time windows. On training days, the shifts involved differences in sleep timing, alarm-driven waking frequency, and the pattern of light exposure and MVPA duration. Sleep was strongly advanced when dancers trained in the morning and when alarms were used, while morning light had a low influence. Sleep was delayed when dancers were more exposed to light and displayed longer MVPA during the late evening. Sleep duration was strongly reduced on weekends and when alarms were used. A small reduction in sleep duration was also observed when morning illuminance was lower or when late evening MVPA was longer. Training in shifts influenced the timing of environmental and behavioral factors, which added up to shape dancers' sleep timing and duration.
