Temperature Hacking for Better Deep and REM Sleep

IN THIS EPISODE OF THE HUMAN UPGRADE™…

…you’re going to learn a bunch of brand new sleep hacks, taken from over a million nights of sleep data.

Those hacks will come from my guest Matteo Franceschetti.

Matteo defines high performance—having been a professional skier, high-level tennis player, competitive race car driver and practicing lawyer. He didn’t get much sleep doing all those things, so he co-founded Eight Sleep and set out to create and advanced sleep improvement device so he, and everyone else, could sleep better and perform better.

We can all agree: “Sleep is a pillar, a fundamental pillar for your health,” Matteo says.

Eight Sleep tracks biomarkers that measure your sleep quality. Then it uses machine learning to make automatic adjustments to your sleep environment. This helps you optimize your sleep, get the reset and recovery your body needs, and well, wake up feeling better than you have in years.

Best of all, you don’t actually have to do anything. You just go to sleep, exactly like you did last night, and the technology does all the sleep hacking for you.

TIME Magazine named Eight Sleep one of its “Best Inventions” of both 2018 and 2019, and Fast Company listed it as one of the most innovative companies of 2018. They’re a sleep hacking company making big inroads into understanding and regulating your body’s temperatures while sleeping. This affects your deep and REM sleep the most.

“While you are in REM your brain deactivates all the temperature controls in the body,” Matteo explains. “It doesn’t let you fall into REM if it’s too hot or too cold because you could potentially die. Changing the temperature based on your sleep stages and the different stages of the night is fundamental to maximize your deep and REM stages.”

And Eight Sleep has a fix for that.

“Based on your sleep stages and based on your biometrics, we adjust your body temperature during the night,” Matteo says. “It’s not that we are inventing the wheel. Your body is already changing temperature during the night. It’s part of your physiological process. We just enhanced that process to maximize your sleep performance.”
