Exercise and Brain Cleanup: What Aging Changes

Exercise and brain cleanup may be more connected than most people realize. This video explores how regular physical activity may help the aging brain clear waste during sleep, why deep slow-wave sleep matters, and what researchers think this could mean for cognitive health as we get older. You’ll learn what the glymphatic system does, how exercise may support sleep, blood vessels, and inflammation control, and why scientists are interested in these links for aging, dementia, and Alzheimer’s risk. This is promising research, but it does not prove exercise prevents dementia.
