How can a smart mattress optimize sleep?

Smart mattresses, specifically those with temperature control features like those from Eight Sleep, can significantly optimize sleep by regulating the sleeper's body temperature. According to Andrew Huberman, the ideal sleep involves a decrease of around 1-3 degrees in core body temperature to fall asleep and maintain deep sleep, and an increase of similar magnitude to wake up feeling refreshed. The Eight Sleep mattress covers enable precise temperature adjustments throughout the night, which can facilitate these optimal temperature variations, enhancing the depth and quality of sleep. This can lead to improved mood, focus, and alertness throughout the day. Dr. Huberman personally attests to the benefits of using an Eight Sleep mattress cover, noting significant improvements in sleep quality and overall well-being after starting to use the product 1 2 3 4.
