Wearables estimate sleep. They do not watch your brain. Treating a 72 as a moral failure is how tracking backfires.
Pick two numbers
Time in bed and midpoint of sleep (how much the clock drifts). Stage breakdowns are entertaining and often noisy. If the score makes you anxious, turn it off for two weeks and see if you sleep better.
- Caffeine creeping later
- Weekend jet lag from 3 a.m. nights
- Training load that coincides with short sleep
Orthosomnia is a real trap
Use it like a notebook you glance at on Sundays.
Some people sleep worse because they chase perfect data. The point of a tracker is better days, not prettier charts. If you feel fine, a mediocre score can be ignored.
