The article says these 6 "tips" are data-driven, yet provides no source or information on why or how the tips actually work. Just that fitness tracker Reddit users "tend to converge on the same set of lifestyle recommendations."

For instance, why does eating before bed affect sleep quality? What kind of times are we talking about here? An hour? Two? Five?

The rest I anecdotally agree with as I have experienced them. But I've never thought my sleep quality suffered due to eating dinner late. What's the reasoning behind that?

Digestion can affect your sleep quality, so having 1-3 hours between your last meal and sleeping is beneficial. There is reasearch on this, but I'm on my phone and to lazy to look it up atm :)

This has confused me.

I have the Oura with all of the features unlocked without subscription. I don't pay anything.

I bought the ring a few years ago. Maybe they provided lifetime membership to older customers?

There are two key assumptions here:

1. All these changes work for everyone. 2. You are just like everyone else.

Maybe it's true. Maybe it's not. The benefit of the tracker would be to find out.

Maybe you don't even have a problem with sleep anyway.

> For those unfamiliar, Whoop and Oura are high-end fitness trackers that require an expensive monthly subscription.

Why is this subscription needed? If you wear the device, can you get the data yourself and analyze it?

Not sure this works.

Yes, we all know the good habits.

A fitness tracker enables a gamification that encourages the daily habits.

Damn, no more easy improvements for me, it seems. Been doing all that for a long time.
