Exercise has long been known to have numerous benefits for physical health, but a recent study suggests that it also plays a crucial role in maintaining brain health. The study, published in the Journal of Alzheimer’s Disease, analyzed brain scans of over 10,000 individuals and found a correlation between regular exercise and larger brain volume.

According to the research, even moderate levels of physical activity, such as taking fewer than 4,000 steps a day, can have a positive effect on brain health. Dr. David Merrill, the director of the Pacific Neuroscience Institute’s Brain Health Center and co-author of the study, stated, ‘We found that even moderate levels of physical activity, such as taking fewer than 4,000 steps a day, can have a positive effect on brain health.’

The study participants, with an average age of 52, underwent whole-body magnetic resonance imaging (MRI) scans to determine their brain volume relative to their exercise levels. The results showed that those who engaged in moderate to vigorous activity, such as walking, running, or playing sports, had larger brain mass in multiple regions responsible for memory, processing information, and various lobes.

Dr. Cyrus A. Raji, another study author, emphasized the importance of exercise in maintaining brain size as we age, stating, ‘Exercise not only lowers the risk of dementia but also helps in maintaining brain size, which is crucial as we age.’

This study adds to previous research that has demonstrated a link between exercise and decreased dementia risk. The findings highlight the potential neuroprotective effects of exercise and the significance of incorporating physical activity into daily routines for better brain health.
