Walking and aerobic activity lower dementia risk for seniors

Experts advise that regular walking, performed with varied pace, arm movement, and occasional inclines, can improve cardiovascular fitness, muscle strength, and endurance without the need for special equipment. Recommended sessions last 30–45 minutes, several times a week, with gradual increases in intensity.

Research shows that daily walking of about 3,800 steps reduces the risk of dementia by roughly 25% compared with fewer steps, and stepping up to 9,800 steps provides additional brain‑health benefits. Other aerobic activities such as dancing, running, swimming, cycling, and strength training also support cognitive function, especially when performed at moderate intensity for at least 150 minutes per week. These findings underscore the role of consistent physical activity in protecting memory and overall brain health in older adults.
