Temperature is the third way your body knows that it’s time to go to sleep - the others are light and food.

Temperature is hard to do with an air conditioner, but when your mattress itself changes temperature throughout the course of the night - it’s a really big deal.

Eight Sleep reacts to what sleep cycle you’re in, paired with dynamic cooling and heating so you get more deep sleep and more REM sleep in less time, so you wake up feeling better.
