Several factors contribute to maintaining a healthy brain as one ages, including regular physical activity, balanced nutrition, and mental stimulation. Engaging in aerobic exercise has been shown to enhance blood flow and support neurogenesis, which is crucial for cognitive function. Consuming a diet rich in antioxidants, omega-3 fatty acids, and vitamins can protect against cognitive decline. Furthermore, activities such as learning new skills, solving puzzles, and social interactions can stimulate brain activity, promoting overall brain health and potentially reducing the risk of dementia.
