Summary

This study tests a smartphone app called StandUPTV that alerts adults after 30 minutes of evening screen time, encouraging them to stand or move. Researchers want to see if this can reduce total sitting time and improve physical activity, sleep quality, and blood sugar levels. The study involves 48 adults who currently sit for more than 3 hours a day and get little exercise.
