The idea
In a 2023 lab trial, five minutes of walking for every thirty minutes of sitting lowered both blood sugar and blood pressure across the day. Shorter or rarer breaks did much less, and other research shows that simply standing does not undo long sitting.
Watches remind you to stand, then count any wrist movement as a win. This pad measures actual time in the chair, and the break only counts if you walked for long enough.
Build plan
- A pressure pad on the seat
- ESP32-C3 timing each sitting bout
- An app that prompts at 30 minutes and reads the phone’s step counter
- Optional: lock the laptop screen until the walk is done
Honest limits
The electronics are easy. The problem is me. Across 18 studies, computer reminders cut sitting by only 12.5 minutes a day. If my own sitting has not changed after two weeks, this build gets shelved and I will say so.
