"A groundbreaking study found that adults who sit for 10 or more hours daily face a significantly higher risk of dementia compared to those who sit less. The research, which tracked over 50,000 adults using wearable devices, revealed that the risk increases dramatically after crossing that 10-hour threshold."
"Here's what happens when we sit for extended periods: blood flow to the brain decreases, reducing the oxygen and nutrients our neurons need to function properly. Dr. David Raichlen's USC research has shown that sedentary behavior is linked to changes in brain regions including the hippocampus, which plays a crucial role in memory. But there's more to it. When we're inactive, our bodies produce fewer growth factors that support brain cell health."
"These proteins, particularly brain-derived neurotrophic factor (BDNF), act like fertilizer for our neurons. Without enough movement to stimulate their production, our brain cells become more vulnerable to damage and decline. The research also shows that prolonged sitting increases inflammation throughout the body, including the brain. This chronic inflammation is now recognized as a key driver in the development of Alzheimer's disease and other forms of dementia."
Adults who sit ten or more hours per day face a substantially increased risk of dementia, with risk rising sharply after a ten-hour daily threshold. A large study tracked over 50,000 adults using wearable devices to measure sitting time. Prolonged sitting reduces blood flow to the brain, lowering oxygen and nutrients to neurons and altering memory-related regions such as the hippocampus. Inactivity suppresses production of growth factors like brain-derived neurotrophic factor (BDNF), weakening neuronal support. Extended sitting also increases systemic and brain inflammation, a recognized driver of Alzheimer's and other dementias. Regular exercise may not fully offset excessive sitting.
