Brain Sleep Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; Representative Director: Atsushi Hirota; hereinafter "Brain Sleep") provided a "Sleep Improvement Program" to employees of SoftBank Corp. (Headquarters: Minato-ku, Tokyo; Representative Director, President & CEO: Junichi Miyakawa; hereinafter "SoftBank"). Overview In this initiative, through "HELPO*1," a service provided by Healthcare Technologies Inc. (Headquarters: Minato-ku, Tokyo; Representative Director, President & CEO: Satoshi Oishi; hereinafter "Healthcare Technologies"), a subsidiary of SoftBank Corp., Brain Sleep provided a "Sleep Type Diagnosis (Sleep Habit Assessment)," classifying individuals into four types. Among those diagnosed with the "Critical Sleep Type," which corresponds to one of the four types, applicants were solicited and selected by lottery to receive Brain Sleep's "Sleep Improvement Program." Before and after the Sleep Improvement Program, the "Sleep Deviation Score for Biz*2" service, which scores sleep, was used to analyze sleep conditions, such as sleep habits and sleep debt, as well as productivity, stress levels, and the risk of sleep apnea syndrome (SAS), identifying issues and areas for improvement. Additionally, Brain Sleep's smartphone application "Brain Sleep Coin*3" was used to visualize one's sleep condition for one month, and special content with proven sleep improvement effects was provided, including sleep improvement content (e-learning seminar videos) and regular sleep columns to raise sleep awareness. 【Participants】SoftBank employees Total: 58 people *Volunteers 【Period】June 20 to July 20, 2023 【Implementation Items】 1. Acquisition of subjective data: Utilizing "Sleep Deviation Score for Biz" before and after the project. 2. Acquisition of objective data: Utilizing Brain Sleep Coin during the project period. 3. Provision of sleep improvement content. 4. Provision of sleep improvement content. 5. Presenting a "Brain Sleep Pillow*4" to some participants who implemented sleep improvement actions, selected by lottery. *1 A healthcare app provided by Healthcare Technologies that allows for one-stop access to chat-based health and medical consultations, online clinic reservations and visits, hospital searches, and purchases of over-the-counter medications (https://healthcare-tech.co.jp/service/) *2 A web service for visualizing sleep provided by Brain Sleep (https://brain-sleep.com/sleep-deviation/) *3 A sleep measurement device & app provided by Brain Sleep (https://brain-sleep.com/sleepcoin/) *4 A pillow provided by Brain Sleep that promotes fast, deep, and brain-resting sleep (https://www.zzz-land.com/shop/g/gBS018S1/) Program Results The main results confirmed in this initiative are as follows: Survey method: Interview-based web service "Sleep Deviation Score for Biz" Participants: Sleep improvement program participants Number of valid responses: 43 (51 in the first round) First round target period: June 19 - June 29, 2023 Second round response period: July 17 - August 1, 2023 ❶ Improvement in Sleep Deviation Score The score improved from 44.2 before the project to 46.3, an increase of +2.1 points. Furthermore, even with an increase of +11 minutes in working hours and a decrease of -12 minutes in sleep duration, indicating a busy work schedule making it difficult to secure sleep, the sleep deviation score improved. This suggests that learning sleep improvement knowledge, utilizing content to review sleep habits, and properly habituating them led to an improvement in sleep quality. ❷ Improved Sleep Quality and Reduced Daytime Sleepiness Sleep quality significantly influenced the improvement in the sleep deviation score. Specifically, it was found that the number of people who responded "good sleep quality" increased by 31 points before and after the sleep improvement program. Improving sleep quality is not only about pre-sleep behavior but also about awake behavior from waking up in the morning until bedtime. The most common behavioral changes observed were "reduced smartphone use before bedtime" and "taking a bath 90 minutes before bedtime." Regarding daytime sleepiness, the percentage of people who reported "sometimes being too sleepy to work" decreased from 75% before the program to 56% after, an improvement of 19 points. ❸ Behavioral Changes and Satisfaction Furthermore, according to a post-program survey, approximately 90% of participants reported being "satisfied" with the sleep improvement program. The most common reason for participation was "having concerns about my own sleep" at 53.8%, followed by "wanting to know more about the quality of my own sleep" at 35.9%. This result clearly shows a strong demand for measurement, especially with the recent spread of measurement devices such as wearable terminals. Moreover, 94.9% of participants reported "changes" in their sleep-related behavior after participating in the program, indicating that many individuals underwent a change in their attitude towards sleep. Specific comments included positive feedback such as realizing the importance of continuously being aware of sleep throughout the program and finding personal sleep measurement interesting. Comment from SoftBank Representative Mr. Yoshihashi SoftBank Corp., HR Planning Department, Health Management Promotion Division (Well-being Promotion Office) Yumi Yoshihashi SoftBank conducts an annual health awareness survey, and recently, there has been increasing expectation for mental health measures. Analysis of health awareness surveys has also revealed that "sleep deprivation" affects presenteeism. Rather than simply trying to "get enough sleep," I believe that the first step to improving sleep is to "understand the quality of one's own sleep." Therefore, I plan to continue implementing "sleep type diagnoses" and similar initiatives to clarify what needs to be done to improve sleep. Future Development Companies promoting health management are constantly seeking measures that their employees find engaging and can sustain. Given the effectiveness of sleep improvement among participants and their high interest in sleep measurement in this project, we believe that the field of "sleep" has proven its validity as the next step in health management. By combining the subjective "Sleep Deviation Score for Biz" (web-based questionnaire) with the objective visualization of daily sleep through the "Brain Sleep Coin" measurement device, we can visualize sleep issues and improvement levels from both subjective and objective perspectives. This allows employees to be highly motivated in their sleep improvement actions. Brain Sleep will continue to promote the use of "Sleep Deviation Score for Biz" and "Brain Sleep Coin" to improve employees' sleep, enhance their health awareness, and improve presenteeism, thereby contributing to increased productivity for more companies.
