Brain Sleep Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; Representative Director: Atsushi Hirota; hereinafter "Brain Sleep") has named the sleep state before waking up, which greatly affects how one wakes up, as "Waking Rhythm," and has newly developed a logic to evaluate this "Waking Rhythm." This "Waking Rhythm," in conjunction with the "Golden 90 Minutes for Falling Asleep" described in "Stanford's Best Sleep" by Seiji Nishino, Brain Sleep's Chief Research Advisor, is a very important method for sleep quality. Brain Sleep will release an updated version of its sleep tracking tool "Brain Sleep Coin" with a new feature to determine "Waking Rhythm" on Thursday, December 19, 2024. Background Brain Sleep believes that sleep does not merely provide rest to the body, but also enhances daytime performance, and that it is crucial to improve the quality of sleep, not just its duration. To date, to emphasize the importance of sleep quality, we have shared the "Golden 90 Minutes" for falling asleep, as advocated by our Chief Research Advisor Seiji Nishino in his book "Stanford's Best Sleep," as well as our proprietary research findings on sleep quality. Now, based on the sleep data accumulated by the sleep tracking tool "Brain Sleep Coin," Brain Sleep has focused on the relationship between the "Waking Rhythm" in the 90 minutes before waking up and subjective evaluations at the time of waking, and will propose a new concept related to sleep quality and incorporate this concept as a new feature in the "Brain Sleep Coin" sleep tracking tool. New Concept: "Waking Rhythm" Influencing How You Wake Up Sleep quality, especially the ease of waking up, is greatly influenced by the "Waking Rhythm." While deep sleep is important during the 90 minutes of falling asleep, it is crucial to wake up from REM sleep or light non-REM sleep without experiencing deep sleep in the 90 minutes before waking up for a refreshing awakening. The "Brain Sleep Coin" allows users to input their morning awakening evaluation, and data has shown that individuals who reported feeling "very good" upon waking experienced less deep sleep in the 90 minutes prior to waking, whereas the occurrence of deep sleep increased as their awakening mood deteriorated. Brain Sleep aims to advocate and establish this new concept by independently developing a function to evaluate "Waking Rhythm" and incorporating it as a new feature in "Brain Sleep Coin." Specifically, "Brain Sleep Coin" will be equipped with a function that determines the occurrence of deep sleep in the 90 minutes before waking and evaluates and displays the "Waking Rhythm" in five stages (VERY GOOD, GOOD, NORMAL, BAD, VERY BAD), with an update release on Thursday, December 19. Comment from Seiji Nishino, Brain Sleep's Chief Research Advisor It is no exaggeration to say that "how well you wake up" determines your entire day. A refreshing and invigorating awakening is a barometer of physical and mental recovery from sleep, and it enhances the fulfillment of your daily work and life. While a precise definition of good sleep is challenging, healthy sleep rhythms and patterns are relatively well understood. Specifically, it is crucial to ensure deep sleep during the first half of sleep, known as the "Golden 90 Minutes." This contributes to alleviating drowsiness, regulating hormone balance, bodily maintenance, and boosting immunity. By dawn, the body naturally prepares for waking. However, due to sleep disorders, sleep debt, or a nocturnal lifestyle, if deep sleep occurs in the early morning, it often leads to a poor awakening, or even if one forces themselves to wake up, an unproductive day ensues. The "Waking Rhythm" proposed and developed by Brain Sleep is an indicator that reflects the quality of awakening and serves as a crucial metric for a healthy sleep rhythm. Similar to sustained deep sleep in the first half of sleep, "Waking Rhythm" is considered an important indicator for ideal sleep. Its visualization will serve as a useful measure to determine what kind of living environment and habits contribute to one's good awakening. This feature is unique and not found in other wearable devices, making it a very beneficial function for users of simple sleep trackers." Seiji Nishino Professor of Psychiatry, Stanford University School of Medicine Director, Stanford University Sleep & Circadian Neurobiology Lab Founder and Chief Research Advisor, Brain Sleep Co., Ltd. Physician, Doctor of Medical Science Certifications: Designated Psychiatrist, Japanese Society of Sleep Research Certified Sleep Specialist, Industrial Physician What is the "Brain Sleep Coin" sleep tracking tool? A sleep tracking tool that converts sleep into value, equipped with a unique measurement algorithm developed based on data accumulated through sleep research. It enables more personalized analysis tailored to individual movements and supports the improvement of sleep quality by proposing a positive cycle where improved sleep habits lead to sleep scores being converted into coins. In this update, we have added a function that evaluates and displays "Waking Rhythm," which particularly affects the quality of awakening, using our unique logic. Daily measurement results show the evaluation of your daily waking rhythm, while weekly/monthly measurement results display an overall evaluation for that week/month in a radar chart, along with other important sleep indicators. The weekly/monthly measurement results will add the "Waking Rhythm" evaluation to the existing evaluations of "Sleep Duration," "Sleep Onset," "Awakenings During Sleep," "Golden 90 Minutes," and "Deep Sleep," determining the overall sleep state with a hexagonal radar chart.
