Brain Sleep Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo, CEO: Kosuke Michibata, hereinafter referred to as "Brain Sleep"), with the cooperation of people who have purchased the "Brain Sleep Pillow," created by our company founder, Nishino, author of "The Stanford Way to Get the Best Sleep," has tested the extent to which mites and mold have grown on pillows that have been used for a long period of time. More than half of people use the same pillow for more than three years! In the "Japan's Sleep Standard Deviation" survey conducted in March of this year, Brain Sleep also investigated how long people have been using their current pillows and how often they replace them. Surprisingly, more than half of people have been using them for more than three years, and more than 30% have been using them for more than five years. As for how often people replace their pillows, more than 40% answered that they do so after using them for more than five years. As can be seen from these survey results, it is thought that many people do not know when to replace their pillows and continue to use the same pillow for long periods of time. Furthermore, the rainy season is known as a time when mold is common, but mold is not the only thing that loves the humid weather. Dust mites are also said to multiply explosively in environments with temperatures of 20°C or higher and humidity levels of 60% or higher. Bedding during the rainy season is the perfect home for dust mites. Over 20,000 mites breed in 5 years !? When mites were detected in pillows (surface and interior) made from both urethane and feather materials, several hundred mites were found on the surface of the urethane pillow, but fewer inside. It is thought that it is difficult for mites to penetrate into the interior of a urethane pillow. On the other hand, while no mites were found on the surface of the feather pillow, tens of thousands of mites were breeding inside. It is presumed that feather material makes it easy for mites to penetrate inside the pillow, and also provides an environment in which they can easily breed. Verification period: June 15th to 29th, 2020 Over 100,000 molds grow in 5 years!? Next, when mold was detected on the same pillows, no significant differences were found on the surface based on material or years of use, but more than 10,000 mold particles were found on each pillow. On the other hand, while there was no difference inside based on material, the longer the pillow was used, the more mold grew, and more than 100,000 mold particles were found on pillows that had been used for more than five years. Verification period: June 15th to 29th, 2020 How do dust mites and mold infestations affect us? The results of this survey show that pillows that have been used for a long time are likely to become breeding grounds for dust mites and mold. As the results of this survey show, it has been reported that an environment where dust mites and mold grow in large quantities can be a cause of allergic diseases such as asthma1), atopic dermatitis2), and nasal allergies3). It is easy to imagine that nasal congestion caused by asthma or nasal allergies can affect sleep. In particular, it is thought that there is a high possibility of being affected in infants and young children whose barrier function is immature. Furthermore, when such allergic diseases affect sleep, the growth hormone secretion rhythm can be inhibited, which can lead to growth disorders4). In more serious cases, it has been reported that sleep-related breathing disorders can also affect brain development5), which can lead to problems such as developmental disorders and attention deficits. The results of this study show that mites and mold live in pillows that have been used for a long time, and that they live in greater numbers inside the pillow. From this, we can surmise that it is quite difficult to remove mites and mold by vacuuming or drying in the sun. For this reason, we would like you to avoid using the same pillow for a long time as much as possible, and to be conscious of keeping your pillow as clean as possible by washing it, especially from the rainy season through to summer, when the proliferation of mites and mold is a concern. BRAINSLEEP PILLOW is easy to clean The BRAINSLEEP PILLOW is breathable and easy to care for. Simply rinse in the shower to wash. Then, place it in a well-ventilated place for about 10 minutes to keep the pillow clean. By washing the pillow and keeping it clean, you can get the best sleep possible.
