The purpose of the study was to investigate seasonal variation in mood and behavior among a group of office workers in Sweden (56°N). Thirty subjects participated in this longitudinal study. The subjects kept a weekly log that included questionnaires for ratings of psychological wellbeing and daily sleep-activity diaries where they also noted time spent outdoors. The lighting conditions in the offices were subjectively evaluated during one day, five times over the year. There was a seasonal variation in positive affect and in sleep-activity behavior. Across the year, there was a large variation in the total time spent outdoors in daylight. The subjects reported seasonal variation concerning the pleasantness, variation and strength of the light in the offices and regarding the visibility in the rooms. Finally, the subjects spent most of their time indoors, relying on artificial lighting, which demonstrates the importance of the lighting quality in indoor environments.
该研究的目的是调查瑞典一组办公室工作人员（北纬56°）的情绪和行为的季节性变化。30名受试者参与了这项纵向研究。受试者每周记录日志，其中包括心理健康评分问卷以及日常睡眠-活动日记，他们还记录了在户外的时间。在一年中的一天内，对办公室的光照条件进行了五次主观评估。积极情绪和睡眠-活动行为存在季节性变化。全年中，在日光下户外度过的总时间有很大差异。受试者报告了办公室光线的舒适度、变化和强度以及房间能见度方面的季节性变化。最后，受试者大部分时间都在室内，依赖人工照明，这表明了室内环境中照明质量的重要性。
