I wore my Apple Watch to bed every night for a year

I wore my Apple Watch to bed every night for a year. Not as a gadget experiment.

I expected charts. I got a shift in how I make decisions.

The single most useful thing was not sleep duration. It was sleep debt. Rise Sleep tracks how much sleep your body still owes itself across multiple days. One bad night is not the problem. Three nights of slightly short sleep in a row is.

That reframe changed everything. I stopped overestimating how rested I am. I started using recovery data to decide when to push on deep work and when to stop pretending I can.

After a year of this: I trust data over feeling fine. Is a dedicated tracker like Whoop actually worth switching to, or does Apple Watch plus Rise already cover enough?
