“This has a profound influence on your alertness, focus, mood, and many other important factors throughout the day.”

“There are a lot of ways to control the temperature of your sleeping environment, but one of the best ways is to control the temperature of your actual mattress-- the surface that you're sleeping on.”

“one of the best ways to make sure that those temperature changes occur at the appropriate times at the beginning and throughout and at the end of your night when you wake up is to control the temperature of your sleeping environment and that's what eight sleep allows you to do”

“The one that I use you you you change how cold it is throughout the night So I think I run it as I think the settings go from 0 to minus 10 like where - 10 is the absolute coldest Zero is no temperature Is that like a point scale or is that degrees no it's a point scale Yeah Yeah Yeah Yeah So so you know I think I get in and I have it at like -5 and then I run it down to minus 10 and then I bring it up to - 5 in the morning something to that effect So I'm taking it from cold to really cold up to cold right okay”
