Episode Details

New research flips the script on sitting and brain health— it’s not just about standing up more, but what you’re doing mentally while seated that matters most. A 19-year study of 20,000 adults found that swapping passive sitting (like TV) for mentally active tasks (like reading or office work) significantly lowers dementia risk. The takeaway? Your brain stays sharp even when you’re sitting—if you keep it engaged. This could reshape public health advice, showing that not all sedentary time is equal when it comes to protecting your mind.
