Episode notes
Screens Turn Interoception Offline
- Screens reduce interoception so we stop noticing bodily cues like needing the bathroom or circulation problems.
- This diminished internal sensing helps explain why people remain seated and engrossed for long stretches.
Prefer Frequent Mini Breaks Over One Big Workout
- Try shorter, frequent breaks rather than one long exercise session because intermittent movement re-oxygenates brain and improves productivity.
- NPR/Columbia trial with 20,000 people showed 80% adherence and productivity rose slightly.
Move Every 30 To 45 Minutes To Clear Brain Fog
- Move before cognitive fog sets in: switch or move every 30–45 minutes to clear CO2 and replenish brain oxygen.
- Gloria Mark suggests 30–45 minutes is the max before attention and decision regions get exhausted.
