A new study has found that regular exercise can significantly reduce the risk of developing Alzheimer's disease. The research, conducted by a team of scientists at Harvard University, showed that individuals who engaged in moderate to vigorous physical activity at least three times a week were 50% less likely to develop the neurodegenerative disease compared to those who were inactive. Furthermore, the study demonstrated that exercise not only lowered the risk of Alzheimer's, but also helped to improve cognitive function and overall brain health in older adults. These findings highlight the importance of incorporating regular physical activity into our daily routines in order to maintain brain health and potentially prevent the onset of Alzheimer's disease. The researchers recommend at least 150 minutes of moderate to vigorous exercise per week for optimal brain health benefits.
