JINS Holdings Co., Ltd. Press release: March 12, 2025 Improving the sleep environment for approximately 100 employees JINS “Neruiku (R)” x Japan Sleep Association x Mitsui Sumitomo Insurance March 14th, “World Sleep Day” is just around the corner! Announcement of changes in feeling of rest when waking up, daytime sleepiness, and concentration by wearing blue light blocking glasses JINS Co., Ltd. (hereinafter referred to as JINS), as part of its “Sleep Education (R)” initiative aimed at resolving social issues related to sleep, jointly with the Japan Sleep Association (hereinafter referred to as Japan Sleep Association) and Mitsui Sumitomo Insurance Co., Ltd. (hereinafter referred to as Mitsui Sumitomo Insurance), a member of the MS&AD Insurance Group, conducted an initiative to improve the sleeping environment for Mitsui Sumitomo Insurance employees. We will announce the verification results of our efforts ahead of World Sleep Day on March 14th. Efforts to improve the sleeping environment for approximately 100 Mitsui Sumitomo Insurance employees JINS and the Japan Sleep Association began offering sleep-related learning opportunities to students last year, with the aim of solving social issues surrounding sleep. This time, we conducted an initiative to improve the sleeping environment of 109 people, mainly employees (operators, administrative and administrative staff, etc.) belonging to Mitsui Sumitomo Insurance’s contact center planning department, and verified the results. Mitsui Sumitomo Insurance promotes health management and is working to improve the health and health literacy of its employees. Particularly in the contact center planning department, operators require a high level of concentration in order to convey the correct information to customers and accurately respond to customer needs. We believe that sleep is an important element in such a work environment, and we decided to implement this program in order to improve the well-being of our employees. Feel more rested by wearing blue light blocking glasses before bed! It has been suggested that it may have a positive effect on daytime sleepiness and concentration The initiative was supervised by Dr. Uchimura, chairman of the Japan Sleep Association. Due to the relationship between blue light and circadian rhythm (body clock), we had employees experience the importance of creating a good sleep environment by wearing blue light-blocking glasses before going to bed, and we also held a special sleep lecture by Dr. Uchimura. In addition, in order to verify the changes caused by this initiative, we conducted a questionnaire survey regarding sleep, daytime sleepiness, and concentration during periods when we did not wear blue
light-blocking glasses before bed and when we did. According to the survey results, the average “feeling of rest”, which is an indicator of good sleep, was 4.24pt during the period when people did not wear blue light-blocking glasses, but rose to 5.64pt during the period when they were worn. Additionally, among those who answered that they woke up twice or more at night, which is said to worsen the quality and quantity of their sleep, 45.33% of them did not wear blue light blocking glasses, but this decreased to 22.67% of those who did. In addition, when asked whether they feel sleepy during the day, 21.33% of the respondents answered “Not applicable” during the period when they did not wear blue light blocking glasses, but this nearly doubled to 52.00% during the period when they wore them. Furthermore, when asked if they had trouble concentrating during the day, 48.00% of people answered “not applicable” during the period when they did not wear blue light blocking glasses, but this increased to 61.33% during the period when they did. These results suggest that wearing blue light-blocking glasses before bedtime may improve a person’s sense of rest and concentration during the day. Comments from Dr. Uchimura, Chairman of the Japan Sleep Association The key points in measuring sleep are sleep duration and sleep rest, which indicates the quality of sleep. Sleep restfulness is a subjective evaluation of whether you feel rested through sleep. A decrease in sleep and rest is strongly associated with a decrease in the degree to which one feels healthy, making it easier to develop mental and physical health problems. In this study, wearing blue light-blocking glasses improved the feeling of sleep and rest, demonstrating their effectiveness. The number of times you wake up at night is also important; if you wake up too many times, the quality and quantity of your sleep will decline, and if you are a working-age person, you need to make improvements if you wake up more than once. After this intervention, the proportion of children who woke up twice or more at night was almost halved.
