We analyzed 62,852 posture readings from 186 desk workers during normal laptop work sessions.
Each reading comes from a webcam-based posture tracker that estimates upper body alignment using pose detection. The system measures things like forward head position, neck angle, shoulder rounding, and torso lean, then converts that into a posture score from 0 to 100.
100 represents upright neutral alignment. Lower scores represent increasing slouch.
The chart shows average posture score as a session progresses.
0 minutes → 73
15 minutes → 70
30 minutes → 65
45 minutes → 59
60 minutes → 54
85 minutes → 52
Posture declines steadily during a single sitting.
The fastest drop happens roughly 20–45 minutes into a session, when people are usually deep in focused work and not paying attention to how they are sitting.
Later in the session there is a small rebound. People likely adjust position once discomfort becomes noticeable, but posture still ends well below where it started.
Values are averages across sessions and smoothed into 5-minute buckets.
This is observational data and the score is not a medical measurement.
