The importance of physical activity for brain health
Physical activity is crucial for maintaining brain health and preventing cognitive decline. Studies have shown that exercise can promote the growth of new neurons in key areas of the brain, such as the hippocampus, which is essential for memory. Both aerobic exercise and resistance training have been linked to cognitive benefits, and combining physical activity with cognitive challenges can enhance these effects. Regular physical activity is especially important in preventing neurodegenerative diseases, such as dementia and Alzheimer's.
