Eight Sleep on The Tim Ferriss Show

That's why I absolutely love the Pod by this episode sponsor, Eight Sleep. I've been using their stuff for many years now. It fits over your existing mattress, tracks your heart rate with 99% accuracy, plus respiratory rate, HRV, and sleep stages. It is wild how much it correlates accurately to the stuff that you wear on you. The Pod's autopilot analyzes your biometrics and automatically adjusts your bed temperature while you sleep, with independent temperature control for couples — also important for domestic peace. Users report falling asleep up to 44% faster. This matches with my experience. I've experimented with countless sleep aids, and I've yet to come across a better solution that both measures and fixes my sleep within the same system. Summers don't need to mean terrible sleep.
