New Research Links Prolonged Sitting to Brain Shrinkage—Even Regular Exercise Can't Offset the Risk
A major new study has found that spending prolonged hours seated each day may shrink the brain and raise the risk of cognitive decline, regardless of how much a person exercises. The findings, which have generated global attention, suggest that even regular physical activity may not be enough to counteract the potentially damaging effects of extended sedentary behavior on brain health, especially in older adults. For Thai readers, who increasingly balance desk-based work with daily commutes and digital leisure time, the message is clear: simply hitting the gym may not be enough—reducing sitting time itself is essential for healthy brain aging.
