Exercise & Your Brain
Why moving your body helps your mind
Regular aerobic activity is one of the most consistent predictors of long-term brain health. It increases blood flow, supports the cardiovascular system the brain depends on, and is linked to slower loss of brain volume with age. The cognitive boost from a single workout is small. The compound effect over years is what shows up clearly in the data.
You don't need to train for a marathon to get the benefit. Decades of research tracking midlife habits find that people who stay regularly active, walking, cycling, swimming, anything that gets the heart up, tend to have better-preserved brain volume and lower rates of cognitive decline later in life than people who are sedentary. The comparison that matters most isn't elite vs. casual exerciser. It's active vs. inactive.
