摘要：

Background: Although exposure to blue light in the evening has been shown to affect sleep, its effects on alertness and work efficiency the next day are not fully understood. Objective: This study aimed to investigate the effects of pre-bedtime blue-light exposure on subjective sleep quality, attention, and work efficiency. Methods: Thirteen young men (aged 20–23 years) without sleep disorders participated in two sessions, in which they were exposed to either incandescent light or blue light 1 h before bedtime. On the next morning, participants underwent assessments of subjective sleep quality, attention, and work efficiency. Objective parameters during sleep were measured using a mat-type sleep meter (sleep scan, SL- 504; TANITA Corp., Japan). Results: Blue-light exposure significantly decreased the ratio of time spent in deep sleep (p < 0.05), reaction times (i.e., attention) during the second half of the 10-min session (p < 0.01), and work efficiency (p < 0.05). Conclusion: The present study suggests that blue-light exposure before bedtime leads to a decrease in the ratio of deep sleep and negative effects on sustained attention and work efficiency. © The Author(s), under exclusive licence to Springer Nature Singapore Pte Ltd. 2024.
