Brain Sleep Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; Representative Director: Atsushi Hirota; hereinafter "Brain Sleep") will launch "Brain Sleep Wear Recovery" (hereinafter "Wear Recovery"), recovery wear certified as a general medical device that provides ultimate fatigue recovery even with limited sleep for Japanese people, who are said to have the shortest sleep duration in the world. It will be available on the Brain Sleep Official Website from April 9 (Wednesday). "Wear Recovery" adopts a lightweight sweatshirt fabric using the newly developed "MEDIC RECOVERY FIBER," and by simply wearing it to sleep, it provides four efficacy benefits: "fatigue recovery," "blood circulation promotion," "reduction of muscle stiffness," and "alleviation of muscle fatigue." The ingredients kneaded into the fabric exhibit a high level of far-infrared radiation function, effectively warming the body and promoting blood circulation, achieving ultimate fatigue recovery. Development Background Recovering from the day's fatigue on the same day is one of sleep's major roles, but as of 2025, the average sleep duration for Japanese people remains short. According to Brain Sleep's survey on sleep duration, while sleep duration showed an upward trend from 2020 to 2024, the latest 2025 survey showed sleep duration to be flat compared to 2024, indicating that the extension has stopped. *1 Brain Sleep believes that in a situation where extending sleep duration is difficult, it is crucial to achieve high-quality sleep and recover from fatigue within a limited time. To maximize fatigue recovery efficiency, Brain Sleep developed "Wear Recovery" as a product. Promoting blood circulation leads to improved fatigue recovery, and a thermographic insulation test using the new material "MEDIC RECOVERY FIBER" confirmed a 2.3℃ increase in surface temperature after 20 minutes of wear. Furthermore, the definition of recovery wear as a general medical device was newly established by a legal revision in October 2022, *2 and simultaneously, "Wear Recovery" will be launched as a general medical device product that clears the new standards *3 set by the Ministry of Health, Labour and Welfare.In a pre-order campaign on Makuake in February 2025, it garnered over 35 million yen in support purchases, with comments such as "I often have short sleep hours, so I have high hopes for its effects," "This is my second purchase, following winter pajamas," and "I expect a lot from this wear, as it's from Brain Sleep, whose pillows are so comfortable." ※1 Brain Sleep "Sleep Aptitude Score Survey® 2025 (n=10,000)" https://brain-sleep.com/pages/research2025※2 Ministry of Health, Labour and Welfare "Handling of clothing, etc. that emits far-infrared rays"※3 Ministry of Health, Labour and Welfare "Regarding the 'Voluntary Standards for Far-Infrared Blood Circulation Promotion Clothing for Home Use' created by the Japan Medical Devices Manufacturers Association" Features of "Brain Sleep Wear Recovery" 01 FULL RECOVERY Proprietary development! New material "MEDIC RECOVERY FIBER" promotes blood circulation Ceramics derived from natural minerals. Among them, several types of highly pure and carefully selected ceramics are blended and kneaded into the fiber at a high concentration to create the proprietary "MEDIC RECOVERY FIBER." Furthermore, a special yarn shape enhances body heat absorption and far-infrared radiation, effectively warming the body, promoting blood circulation, and achieving high recovery effects. Surface temperature increases by approximately +2.3℃, effectively warming the body.Wearing it effectively warms the surface temperature, leading to improved blood circulation. Expect not only fatigue recovery but also increased relaxation.In today's stressful society, it is also important to relax and alleviate stress. In electroencephalogram measurements that gauge relaxation levels, the increase rate of alpha waves, observed during relaxation, improved by approximately 21% compared to conventional products. 02 STRESS FREE & RELAXRelaxed fit with high moisture absorption/release & lightweight sweatshirt fabricThe outer surface uses quick-drying polyester, while the inner surface uses a proprietary fabric with high moisture absorption and release properties, made from natural cotton and rayon. This sweatshirt fabric is lighter than typical sweatshirt fabrics, reducing the burden on the body. *1Additionally, its overwhelming moisture absorption and release power eliminates stuffiness. The excellent moisture-absorbing and quick-drying fabric provides a comfortable, non-stuffy wearing experience. ※1 While typical sweatshirt fabrics are 9-13 oz, "Wear Recovery" achieves a lightness of 7 oz. Comfortable range of motion, designed for sleep, with no constriction.This sleep-specialized wear does not hinder necessary tossing and turning during sleep. The armholes are set to be larger, and constriction by elastic or ribs is minimized. Features like drop shoulders that provide ample room around the shoulders, side vents that allow for looseness at the hem, and ribs with minimal constriction ensure a comfortable range of motion. The pants have a relaxed silhouette with ample room around the ankles. 03 PERFECT CLEANQuick-drying and antibacterial to prevent bacterial growth, for cleanliness and comfortIt dries quickly after washing, allowing for clean wear even on busy days. Additionally, its stronger bacteriostatic action (compared to antibacterial) prevents bacterial growth and deodorizes unpleasant sweat odors.
