You wake up feeling fine. Then you check your sleep score, see a 62, and suddenly the whole day feels heavier.
Sleep researchers have a name for this. In a 2017 paper, clinicians described patients so focused on improving their tracker data that the effort was making their sleep worse. They called it orthosomnia.
Here is the catch. Your wrist device measures movement and heart rate, then estimates the rest. It is reasonably good at total sleep time and much less reliable at telling you how much deep or REM sleep you got. Two devices will give you two different answers about the same night.
There is also research showing that people told they slept poorly performed worse on attention tasks, regardless of how they actually slept. The belief did real work.
If you want to keep tracking, read trends over weeks instead of grading individual nights. And notice how you feel before you look at a number.
The basics still do the heavy lifting. Same wake time, morning daylight, cool dark room.
Do you check your sleep score every morning? Be honest. 😅
