Brain Sleep Inc. (Headquarters: Chiyoda-ku, Tokyo; Representative Director: Atsushi Hirota; hereinafter "Brain Sleep") has signed a sleep support sponsorship agreement with <DONUTS VARREL> (hereinafter "VARREL"), one of Japan's leading professional teams in the "e-sports" industry. While the "e-sports" market in Japan continues to expand and is projected to approach 20 billion yen by 2025*1, a decline in sleep quality caused by factors such as prolonged screen viewing, which can be a health risk, and a nocturnal lifestyle rhythm, is being viewed as problematic*2. In a unique sleep improvement program conducted by Brain Sleep with the <VARREL> Overwatch division in 2024, the company successfully visualized and improved sleep conditions, leading to results that suggest an improvement in play performance*3. Moving forward, Brain Sleep will provide continuous sleep support to athletes, including those in other divisions of <VARREL>, and further promote the importance of sleep to the entire "e-sports" industry. *1 "Japan eSports White Paper 2024" published by the Japan eSports Union (JeSU) and Kadokawa ASCII Research Laboratories.*2 Lee S, et al. (2021). Int J Environ Res Public Health, 18, 664.*3 https://prtimes.jp/main/html/rd/p/000000243.000046684.html Background of the Initiative Brain Sleep aims to contribute to performance improvement by enhancing sleep quality, and to achieve this, the company disseminates accurate sleep information and develops and sells products and services."e-sports" players are often said to suffer from chronic sleep problems due to prolonged screen viewing, nocturnal lifestyles, and exposure to stimulating images and sounds. Brain Sleep focused on these industry-specific sleep challenges and in November 2024, conducted a visualization of sleep conditions for players in the <VARREL> Overwatch division. This revealed two major sleep issues: "delayed sleep rhythm" and "increased sleep latency (time from going to bed to falling asleep) and wakefulness during sleep (time spent awake during sleep)." In an effort to resolve these issues, a unique sleep improvement program was implemented, which resulted in an improvement in sleep quality, such as an earlier sleep rhythm and extended deep sleep. Furthermore, this led to an improvement in play performance, with the team jumping from 3rd place in the previous year to winning the "Overwatch Champions Series 2025 Japan." Based on these results, Brain Sleep will support the sleep of players in other divisions of <VARREL> and also disseminate the importance of sleep to the "e-sports" audience, thereby contributing to solving sleep problems across the entire "e-sports" industry in Japan. Future Initiatives By further deepening our collaboration with <VARREL>, we will continue and expand the following initiatives to promote the importance of sleep in the e-sports industry.1.Continuous Sleep Monitoring and Improvement of Sleep Improvement Programs・Continuous monitoring of athletes' sleep conditions and implementation of improvement programs.・Development of more personalized sleep improvement programs tailored to individual athletes.・Expansion of successful cases from the Overwatch division to other VARREL divisions.2.Strengthening Awareness Activities for the e-sports Industry・Dissemination of the importance of sleep not only to e-sports players but also to their audience.・Support for sleep awareness activities by VARREL athletes. Comment from Fumio Suzuki, President and CEO of CELLORB Inc. We are truly delighted to have signed a sponsorship agreement with Brain Sleep.To achieve high performance in competitive scenes, physical and mental conditioning is as essential as daily effort. Among these, I strongly feel that sleep is an "invisible foundation" that is equally or even more important than any training or strategy.Brain Sleep is dedicated to improving sleep environments through a scientific approach, and their support is incredibly reassuring as we move to the next stage. Through this partnership, we will strive to improve player performance and also promote the importance of "health" and "sustainable competitive careers" in e-sports.
