Brain Sleep Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; CEO: Atsushi Hirota; hereinafter referred to as "Brain Sleep") has begun sales of the "Brain Sleep Comforter Perfect Cool" (hereinafter referred to as "Perfect Cool"), which provides the ultimate in coolness and comfort that lasts from the time you go to bed until the morning, in preparation for the hot and humid summer months when it is difficult to sleep. Development Background An unusually early summer and unique sleep challenges According to the Japan Meteorological Agency, this summer is likely to be covered by warm air, with temperatures expected to be normal or higher than average, especially in northern, eastern and western Japan. There are concerns about the rapid rise in temperatures, with the earliest midsummer day on record already being observed. When temperatures suddenly rise, people are unable to acclimatize to the heat (the body does not get used to the heat), and there is a higher chance of suffering from heatstroke even at relatively low temperatures. Since May, approximately 800 people have been rushed to hospital, and health damage is already occurring. It is said that approximately 40% of heatstroke cases occur at night or while sleeping each year, so even more caution and measures are needed. Additionally, major electric power companies are raising electricity bills, with increases of up to 40%, raising concerns that this will place a further burden on households. The importance of the bedroom environment Indoor temperature and sleep quality are closely related, and research has shown that as indoor temperatures rise, sleep comfort decreases and awakenings increase. It is known that the probability of sleep disorders such as waking up during the night increases, particularly in environments where the minimum nighttime temperature is 25 degrees or higher, so it is important to pay close attention to the indoor temperature. In addition to the heat, summer sleep poses many challenges throughout the year, including the risk of dust mites due to humidity, high electricity bills for air conditioners, the cold air from air conditioners, and temperature differences. This time, we have developed the ultimate long-lasting cooling duvet as a solution to these summer-specific challenges.

I'm looking forward to buying the summer version too." ・I'm looking forward to being able to save on my electricity bill. ・"I want to get rid of those uncomfortable summer nights! I'm looking forward to it." ・"I hope that this will make nighttime sleep that relies solely on air conditioning a little more comfortable, and help me get a good night's sleep while saving energy." Brain Sleep Comforter Perfect Cool Features Lasting, ultimate coldness. Space technology is used to provide ultimate coldness that lasts, not just for a moment. An innovative duvet that provides even greater comfort and cleanliness When covered with Perfect Cool, the body surface temperature dropped from 34.4℃ (same as the outside temperature on a hot day) to a comfortable 20.9℃. It was proven that covering yourself with a blanket is cooler and more comfortable than not covering yourself with one. *The sample is placed on a hot plate that represents human body temperature, and then the surface temperature is measured when it is moved onto an insulating material. TECHNOLOGY 1. PERFECT COOL The ultimate in long-lasting coolness We developed this material from the thread to the fabric in pursuit of the ultimate cooling sensation. A material that can be labeled as a cooling material requires a q-max value of 0.2W/cm2, but Perfect Cool has a q-max value of 0.524W/cm2, which is approximately 260% of the standard value for a cooling sensation on contact, achieving the ultimate cooling sensation. *The q-max value is the "contact cooling value (W/cm2)" and is a value used to express and judge the contact cooling sensation of a product. A material can be labeled as contact cooling if it is 0.2 or higher, and the higher the value, the greater the cooling sensation. *Perfect Cool's q-max value of 0.524 is divided by the standard value of cool to the touch of 0.2 to get a calculation of approximately 260%. Space technology PCM used for lasting cool sensation The fibers of the comforter contain microencapsulated PCM, an innovative cooling technology developed for space suits. With ordinary cooling bedding, the cooling effect is lost when the absorbed heat becomes saturated. With Perfect Cool, when the comforter separates from the body due to tossing and turning during sleep, the cooling technology is restored and the cooling effect is sustained. *PCM: abbreviation for phase change material 2. PERFECT COMFORT Comfortable even during the hot and humid rainy season Cool and smooth to the touch, comfortable against the skin, and non-humidifying for a comfortable sleep By using a special microfiber in the fabric, we have achieved a smooth, soft and extremely comfortable feel. In addition, the entire duvet absorbs and releases moisture, allowing you to sleep in a dry sleeping environment even in humid seasons. 3. PERFECT CLEAN No need for a cover, so it stays clean and comfortable Because the filling is hydrophilic, the inside of the futon can be thoroughly cleaned, so there is no need to worry about dirt or mites inside.
