We challenge the idea that all sitting harms your health and follow new evidence showing the brain cares more about mental effort than posture. We break down how “active sitting” may build cognitive reserve and why small changes to downtime can reshape long-term dementia risk.
• the anxiety behind “sitting is the new smoking”
• why dementia develops over decades, not suddenly
• how a large Swedish cohort study tracks seated habits
• passive sedentary time versus active sedentary time
• what “cognitive reserve” means for brain health
• why the results matter but do not prove perfect causation
• how generic “sit less” questions miss crucial context
• realistic swaps like 30 minutes of reading or puzzles
• turning TV into an active task by talking about it
