Sleep tracking always seemed like nonsense to me. You either know you are getting restful sleep or know you are not, and if you are not time is probably better spent taking a proactive approach to establishing healthier lifestyle habits that will lead to more restful sleep. How much is it worth really, to wake up and know exactly how much time you were tossing around not getting rest? I’d imagine you would feel it, statistics or not.

Not true. A lot of people with chronic sleep problems (e.g. sleep apnea) feel tired during the day but have no idea why, and don't wake up during the night or have any other direct symptoms that would lead them to have a strong hypothesis for "bad sleep" being the root cause.

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.

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.

It's very useful information when you are never rested and constantly are trying to tweak variables to observe the impacts to your sleep. I've long since stopped relying on trackers, however, as nothing seemed to display any accuracy whatsoever. I manually record my perception of sleep every night.

Datapoints for each night can help you isolate the causes of poor sleep in your life. An objective measure, even a flawed one, can help a lot in that process.
