To investigate the effects of 8000 lux morning bright light in the elderly, home-based motor activity on sleep was monitored for 5 days in 10 healthy women (mean age: 59.7 years old, range: 50-69 years old). The activity level and movement index on night 4 were significantly lower in bright light conditions, compared with the controlled condition. The activity level during the day was not significantly different between the two conditions. These results indicate that 8000 lux morning bright light improves sleep quality in healthy elderly women.
为研究8000勒克斯早晨强光对老年人的影响，对10名健康女性（平均年龄：59.7岁，范围：50 - 69岁）在家中的运动活动进行了5天的睡眠监测。与对照条件相比，在强光条件下第4晚的活动水平和运动指数显著降低。两种条件下白天的活动水平没有显著差异。这些结果表明，8000勒克斯早晨强光可改善健康老年女性的睡眠质量。
