The dual-reset break
The fix
Every ~45 min: reset your posture AND look 6 m away for 20 seconds.
Why it happens
One micro-break fixes two systems at once — it unloads the neck/back and relaxes the eye-focusing muscles while restoring your blink rate.
If you ignore it
Regular micro-breaks measurably reduce discomfort and keep both posture and blink rate from collapsing over long sittings.
