Brain Sleep Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; Representative Director: Atsushi Hirota; hereinafter "Brain Sleep") will launch "Brain Sleep Haramaki Recovery" (hereinafter "Haramaki Recovery"), a next-generation Haramaki made of recovery material that focuses on cold sensitivity and breathing to improve sleep quality, on the Brain Sleep official website starting August 6 (Wednesday). In our living environment, "factors that cool the body" are increasing with rising temperatures and humidity. However, excessive that occurs unconsciously affects the autonomic nervous system and leads to a decline in sleep quality. As the second product in the "Brain Sleep Wear Recovery" general medical device series, which has been well-received since its launch, "Haramaki Recovery" uses the independently developed material "Medic Recovery Fiber" to protect the abdomen, the core of the body, from cold. Furthermore, focusing on the modern problem of "breathing," it incorporates a unique sleep compression design called to support deep breathing, guiding the diaphragm back to its correct position for deeper breaths. Simply wearing it while sleeping helps care for breathing while protecting against , supporting improved sleep quality. Development Background Factors causing are increasing throughout the year, such as increased and prolonged air conditioner usage and higher consumption of cold drinks. places a burden on the autonomic nervous system, such as decreased internal organ function (e.g., gastrointestinal tract), poor blood circulation, and rapid body temperature regulation due to temperature changes. This can disrupt the natural switch to the parasympathetic nervous system, hindering smooth sleep onset. Brain Sleep's proprietary research found that the period when people feel the most cold during the day is "night to morning" (*1). Especially in summer, in addition to difficulty sleeping and kicking off blankets, and being prone to sweating, the constant use of air conditioning during sleep leads to excessive . It was also found that the discomfort caused by is felt in the "abdomen (abdominal pain/discomfort)."The "Haramaki Recovery" uses the far-infrared radiant heat function of its recovery material to naturally warm the abdomen. Furthermore, deep breathing is important for sleep quality and autonomic nervous system regulation. According to breathing consultant Takashi Onuki, many modern people have a raised diaphragm, which narrows its range of motion and leads to shallow breathing becoming habitual. Therefore, under his supervision, we independently designed for sleep, applying appropriate pressure around the diaphragm to return it to the correct position and guide users to deep breathing where they inhale and exhale fully. *1 Brain Sleep user survey: Response period July 10-21, 2025 (n=297 people) Features of "Brain Sleep Haramaki Recovery" 01 GENTLE WARMNewly developed material MEDIC RECOVERY FIBERA new material developed for general medical device recovery wear. It uses "MEDIC RECOVERY FIBER," a proprietary material made by blending several types of highly purified and carefully selected ceramics derived from natural minerals, and kneading them into the fibers at a high concentration. 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 +1.9°C, concentrating heat on the abdomen, the core of the body.Wearing it effectively warms the abdomen.02 SLEEP CORE COMPRESSIONA uniquely designed structure for deep breathing, leading to deep sleep.The position of the diaphragm is crucial for deep breathing, but it has been found that many Japanese people have a raised diaphragm, leading to shallow breathing. We created a unique compression structure with stronger compression at the top and slightly weaker compression in the center and bottom, adopting to help raise the diaphragm. By applying appropriate pressure around the diaphragm and positioning the ribs and diaphragm correctly, it enables full exhalation and leads to deep breathing. After repeated prototyping, we arrived at an exquisite compression that is comfortable to wear even during sleep.03 COMFORT & CLEANNot too tight, highly stretchableMade of highly stretchable material, it offers an excellent comfortable fit. It can be worn like an undershirt.Eliminates unpleasant stuffiness while wearingIt is quick-drying and dries quickly after washing, so you can wear it cleanly even on busy days. Furthermore, its anti-bacterial action, which is superior to antibacterial properties, prevents the growth of bacteria and deodorizes unpleasant sweat odors.

Athletic Trainer. Supervised 'Sleep Planner' sleep qualification)Specially Appointed Researcher, Graduate School of Medicine, Osaka UniversityOperates "Breathing Specialty Salon Breathe Please" in Kyoto. Author of "Basic Breathing," etc.＜Mr. Onuki's Comment＞While breathing is something we do unconsciously, we actually "move" 20,000 times a day, and it is believed that about 90% of people do not have proper breathing "movement." In fact, there are reports that even 90% of athletes do not have proper breathing movements. At the same time, through our joint research with Brain Sleep, we have found that deep breathing leads to deep sleep. Of course, in addition to deep breathing habits before bed, by wearing this Haramaki, the exquisite compression supports breathing movements, which we believe has the potential to lead to deeper sleep.
