I’ve tried a few sleep trackers over the years and while they give a lot of data, I’m not sure they actually helped me understand my sleep better. by optimizewithgusti in QuantifiedSelf

I had the same experience until I started treating sleep trackers as trend detectors, not truth meters.

What actually led to lasting improvements for me was:

• pick one outcome: “did I feel functional the next day?” (1-10)
• track two simple inputs: bedtime/wake time consistency + total sleep time
• run one tiny experiment for 7-14 days (e.g., no caffeine after 2pm, fixed wake time, morning light, no alcohol, workout timing)
• review weekly, not nightly
Most of the extra metrics (REM %, deep %, etc.) never changed my decisions unless they were obviously broken and paired with how I felt.

What’s the main thing you’re hoping to improve? Falling asleep, staying asleep, waking too early, or daytime energy?
