OBJECTIVE
We evaluated the efficacy of a combined short-wavelength-enriched white light and exercise fatigue countermeasure during breaks for flight controllers working overnight shifts.
METHODS
Twenty NASA flight controllers were studied for two blocks of nightshifts in ISS mission control, randomized to either the control or countermeasure condition. The countermeasure constituted passive exposure to blue-enriched polychromatic lighting for three 20-minute intervals, which included 10 minutes of exercise and occurred before and twice during their shifts. Alertness, performance, and mood were evaluated.
RESULTS
Flight controllers reported being significantly more alert (P < 0.0001) and happy (P = 0.003) and had faster reaction times (10% slowest responses; P < 0.05) during the countermeasure condition compared to control.
CONCLUSIONS
The combined light and exercise countermeasure improved alertness, performance, and mood in shift workers overnight. Further research is necessary to determine their relative contribution.
目的
评估在夜间轮班期间，短波长富集白光与运动疲劳对抗措施相结合对飞行控制器的功效。
方法
对 20 名美国宇航局的飞行控制器进行了两项国际空间站任务控制夜间值班的研究，随机分为对照组和对抗措施组。对抗措施包括在三个 20 分钟的时间段内被动暴露于富含蓝光的多色照明下，其中包括 10 分钟的运动，并且在轮班之前和期间进行两次。评估警觉性、表现和情绪。
结果
与对照组相比，飞行控制器报告在对抗措施条件下警觉性（P<0.0001）和幸福感（P=0.003）显著提高，反应时间更快（10%最慢的反应；P<0.05）。
结论
综合光照和运动对抗措施可提高夜间轮班工人的警觉性、表现和情绪。需要进一步研究以确定它们的相对贡献。
