I've tracked sleep using a number of devices and algorithms and I haven't found a single one that regularly aligns with what and how I feel. I know it's tracking real data, but the conclusions feel completely made up. What are other people's experience -- especially from those who are more bullish about sleep tracking?

I use an Android app called "Sleep", it just works by accelerometer with your phone on the corner of your bed. I've found it's not really good with its automatic rating and suggestions, but the activity graph has an extremely reliable wave pattern on the mornings I am well rested. Like an hour and a half of no movement at all, then an hour of restlessness, which repeats through the night. Usually the hour of restlessness even has the same pattern each time it happens. But any other pattern and I generally feel tired the whole morning.

Originally I got this app for its alarm, it tries to go off in the half hour before the alarm time when you're already partially awake. The sleep tracking was just a bonus.

People used to sleep with watches 50 years ago too. You just get used to it.

True. Though the difference with smart watches is that they tend to be significantly bigger in size than what common watches used to be like. Smart "bands" tend to be less perceptible.

I think it depends what kind of smartwatch you choose. It should fit your wrist. The amount of people I've seen with e.g. a Galaxy Ultra watch that stands over their wrist on both sides is staggering to me.

For me, the Galaxy Watch 7 in 44mm fits perfectly

> exercise-induced fatigue impairs complex cognitive tasks

Apparently your study is strictly about cardio.

Heavier compound lifts can surely knock me out for 30 minutes to 2 hours. I don't know how in the heck people train in the mornings. But a lot of this is because they are complex cognitive tasks.

Mornings (~6am), I often walk ~40min to my gym, do heavy compound lifts (~1hr total with ~2-3min rest between sets), walk ~40min back, and I tend to feel fine by the time I get back home. It's usually at the end of the day where the fatigue seems to catch up to me.

Surprisingly, I find the Apple Watch significantly more comfortable and less perceptible than any other watch I've worn in the past. My theory is it's the contoured back for the heart rate monitor, etc. But maybe I'm just weird.
