Subjects fell asleep rapidly with both mattress pads. Interestingly, the core body temperature rapidly and continuously decreased with airweave and reached the nadir (36.0 C) at 2:00-3:00, while a decline in the temperature with a low-rebound mattress pad was modest and remained 0.4 C higher than that with airweave between 1:00 to 2:00. Since a significant difference in the core temperature was observed in the initial phase of sleep, PSG data was also analyzed, and a significant increase in Stage 4 sleep was found with airweave.In general, it is said that a rise and fall in the core temperature when falling asleep is important for sleep quality, and a sudden and deep decline in the core temperature induces better sleep. As mentioned above, airweave induces better quality of sleep due to a rapid and continuous decline in the core body temperature. The increased amount of deep sleep occurred in association with changes in the core temperature observed. Note 1: Compared the high rebound "airweave" and a typical low-rebound mattress pad Reference Material:Research on sleep and growth hormone In general, it is said that good-quality sleep has a strong effect on the secretion of growth hormone. It is also a common understanding that growth hormone promotes skin and cell repair, recovery from fatigue and growth of young children. airweave inc. will continue the sleep research, including studies like the one in this release, and contributing to the comfortable life of everyone.
