I had an Oura ring for a while and found it to be quite accurate. Using it, I found myself adjusting my routine to prioritize sleep.

> You either know you are getting restful sleep or know you are not...I’d imagine you would feel it, statistics or not.

How I feel doesn't always correlate with good sleep. It's just one variable. Knowing whether my sleep is good lets me know that I should be looking at other problems.

Or, in some cases, I am in bed for eight hours, but the quality of my sleep by the numbers is bad. It's not that I'm not getting enough sleep, it's that something is affecting my sleep. Spicy food too late in the evening? Too much caffeine? Not enough hydration throughout the day? It's hard to be mindful of the things that make my sleep worse unless I actually know when my sleep wasn't great.
