光照的抗抑郁和促进睡眠的作用可能对治疗与年龄相关的情绪和睡眠障碍有用。鉴于最近有证据表明晨光有益，这项研究调查了情绪和睡眠与晨光照射、24小时环境照明以及志愿者卧室窗户在早晨被遮盖的程度之间的关系。我们调查了459名绝经后妇女，她们参加了一项由美国加州大学圣地亚哥临床中心开展的妇女健康倡议的辅助研究。在基线，志愿者们完成了一份为期4周的睡眠回忆问卷。随后，研究人员用腕部活动记录仪对志愿者在家中进行了5-7天的评估。在家庭录音期间，评估自我报告的情绪。计算起床后4 h的早晨照度、24 h照度均值（余弦拟合平均值）和光照顶相（余弦拟合峰值时间）。每晚使用经过验证的手腕活动记录法对睡眠进行评分。每天早上完成睡眠日记。在两个24小时的时间段内，在清醒期间大约每2小时收集一次尿液，在睡眠期间收集一次排尿。余弦拟合确定了尿6-亚砜氧褪黑素（aMT6s）排泄的高峰期。早晨照明和24小时照明与更好的情绪和睡眠有一定的联系。相对于组中值，生物钟延迟的受试者，光线与情绪和睡眠的关联始终更大。研究对象卧室里较少的晨窗覆盖与更多的晨光和较少的抑郁情绪有关。结果表明，早晨和24小时的光照可能对老年人有益。
The antidepressant and sleep-promoting effects of light exposure might be useful for treating age-related mood and sleep disorders. In view of recent evidence suggesting beneficial effects of morning light, this study examined the associations of mood and sleep with morning light exposure, 24 h environmental illumination, and the degree to which the volunteers’ bedroom windows were covered in the morning. We examined 459 postmenopausal women participating an ancillary study of the Women’s Health Initiative conducted at the University of California, San Diego Clinical Center, San Diego, CA, USA. At baseline, volunteers completed a 4-week sleep-recall questionnaire. Volunteers were then assessed for 5–7 days in their home environments with actigraphic wrist monitors. During home recording, self-reported mood was assessed. Morning illumination during the first 4 h after arising, 24-h illumination mesor (cosine-fitted mean), and illumination acrophase (cosine-fitted peak time) were calculated. Sleep was scored each night using validated wrist actigraphic methods. A sleep diary was completed each morning. During two 24-h periods, urine was collected approximately every 2 h during wakefulness and following any voidings during the sleep period. Cosine-fitting established the acrophase of urinary 6-sulfatoxymelatonin (aMT6s) excretion. Morning illumination and 24-h illumination were modestly associated with better mood and sleep. Associations of light with mood and sleep were consistently greater for subjects whose body clocks were delayed relative to the group median. Less morning window covering in the subjects’ bedrooms was associated with more morning light and less depressed mood. The results suggest that both morning and 24-h light exposure may be beneficial for older adults.
