Referencing this recent article from the NY Times:
By and large I have to agree with the conclusion that we don’t really know what to do with the information.
There was a comment where the person pointed out that the sleep tracker at least gave him some insight into his sleep after lifestyle choices (drinking, going to be late, etc.).
I am using the “Autosleep” app that was referred to in the article. One thing he didn’t mention was that the app references a “sleep bank” and tries to get you to average out to whatever you say your nightly requirement is (defaults to 8 hours). And then proposes wildly inappropriate go-to-sleep times for that night to “catch up”.
1) Nothing has come close to the UP! wristband for mapping my sleep habits (it had its own issues about not being able to edit the results when it recorded incorrectly)
2) the fitbit is between the UP! and the Apple Watch. It was OK but very coarse.
3) The apple watch is pretty good. I appreciate that “Autosleep” tries to take a holistic view of things and considers your overall sleep in conjunction with what it records as “Deep sleep” and something else called “Quality sleep” and then adds a dash of your average heartbeat and your wakeup heartbeat and something they call “Heartrate variance” to come up with a comprehensive assessment of your sleep status.
Now if only we had any scientific evidence that any of the above actually means anything, I would be much happier. But I suppose that’s one of the points of the original article.
But my perception that the Apple Watch (and any wrist-based tracker I’ve tried. Not mentioned is Intel’s Basis Peak which I rather liked but disappeared pretty quickly) is still relatively crude for sleep tracking does not instill confidence in me in any ratings/statistics generated.
I’m at the point now where I’m thinking of not bothering with sleep tracking anymore in favor of waking up to a fully charged watch so I don’t have to think about topping it up during the day….
