Brain Sleep Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo, CEO: Atsushi Hirota, hereinafter referred to as "Brain Sleep") will develop and sell "Brain Sleep Wear Perfect Cool (hereinafter referred to as Wear Cool)," sleepwear that provides a cool and moisture-wicking cooling sensation to keep you comfortable during the increasingly long-lasting heatwaves. Reservations for "Wear Cool" will begin at 10:00 a.m. on Sunday, March 31, 2024 on Makuake, a supportive purchasing service for new products and experiences. Development Background According to the Japan Meteorological Agency, the national average temperature (※1) from June to August 2023 is expected to be 1.76°C higher than average, significantly exceeding the previous record of 2010 (1.08°C higher than average) and the highest since statistics began in 1898. The year was a difficult one, with the entire country experiencing extreme heat and a succession of health problems in various areas. In addition, the forecast for June to August 2024 (※2) predicts that temperatures will rise nationwide as warm air covers the country. As temperatures rise, the risk of heatstroke also increases, but it is said that about 40% of heatstroke cases occur at night or while sleeping, so caution and measures must be taken even while sleeping. It is said that we sweat about a cup's worth while sleeping, and if the sweat and moisture generated during sleep is left unabsorbed, it can actually make the body cooler and increase the risk of health problems such as catching a cold. In addition, continuing to use bedding that has been soaked with sweat can lead to the proliferation of bacteria, causing odors and mites and mold. During the uncomfortable summer nights that are common from the rainy season to the heatwaves of summer, absorbing moisture and sweat is extremely important for a comfortable and high-quality sleep. "Wear Cool" was developed with the aim of allowing you to stay comfortable until morning by using a special material that absorbs moisture and sweat generated during sleep and lowers the temperature. *1 Press release for 2023, Weather in Summer (June to August), Japan Meteorological Agency *2 Explanation of the warm season forecast (announced on February 20, 2024) by the Japan Meteorological Agency Features of "Brain Sleep Wear Perfect Cool" 1. PERFECT COOL The ultimate dual cooling technology of cooling to the touch and moisture absorption provides a cooling effect of 260%! The highest level of cooling sensation that you can feel the coolness from the moment you put it on. To achieve the ultimate cooling sensation, we used cooling nylon for the core of the thread and polyethylene with even higher cooling sensation for the periphery, developed ultra-fine threads consisting of about 100 fibers, and developed a unique fabric by weaving the ultra-fine threads with nylon threads and polyurethane threads using a special technique. By adopting this uniquely developed fabric, we achieved the ultimate cooling sensation with a cooling sensation value of 0.524 (a value that indicates the amount of heat transferred from the body to the fabric; the higher the value, the cooler it feels) that is about 260% higher than the standard value of 0.2 (which is just slightly cool to the touch). * Cooling sensation value of approximately 260% of the standard 0.2 of cooling sensation (q-max: W/cm2) The ultimate moisture absorption cooling sensation of up to -7.7℃ when damp while you sleep. Our uniquely developed cooling fabric has been further processed with an innovative moisture-wicking cooling effect. As a result, it absorbs moisture and sweat that occurs during sleep, lowering the surface temperature and effectively cooling the body. The cooling effect has been confirmed even after 50 washes. 2. SUPER CLEAN Antibacterial and deodorant treatment keeps it clean every day, even in summer. Its antibacterial and deodorizing function is 2.5 times higher than the standard antibacterial activity value (2.2), preventing the proliferation of bacteria in the summer. Its effectiveness remains unchanged even after 10 washes. (Antibacterial activity value: reduction rate of Staphylococcus aureus) 3. RELAX & COMFORT The two-layer fabric provides stress-free comfort. The skin side is made of a cool fabric with a smooth feel and moisture-absorbing and diffusing properties, while the surface is made of 100% cotton fabric with high moisture absorption properties, making it gentle on the skin and designed to eliminate stuffiness. Eliminates the unpleasant stuffiness while sleeping. The combination of highly absorbent and hygroscopic materials absorbs and releases moisture that inhibits comfortable sleep, effectively regulating humidity so you can stay comfortable even when you sweat. The design is comfortable and does not restrict the body, supporting sleep. This sleepwear reduces stress by maintaining a comfortable range of motion, with larger armholes and no excessive tightness from elastic or ribbing, to ensure comfort when relaxing before falling asleep and to allow you to turn over during your sleep.
