Regular physical activity, including aerobic, resistance, balance, and dual-task training, reduces the risk of dementia and cognitive decline by enhancing neurogenesis, improving cerebral blood flow, and increasing brain-derived neurotrophic factor (BDNF).

Aim for 150-300 minutes of moderate aerobic activity (like brisk walking) or 75-150 minutes of vigorous activity per week. Add strength and balance exercises twice a week. If you prefer cultural practices like Tai Chi or yoga, these are excellent alternatives that also support cognitive health. Start with what you enjoy and gradually increase intensity.
