No one can argue that physical exercise is important for the health of your body, but evidently it also keeps your brain sharp. Two new studies were presented at the 2011 Alzheimer’s Association International Conference in Paris that added to the growing body of research suggesting that exercise can help protect your brain against mental decline that occurs with aging.
Physical exercise in general increases blood flow to all cells, tissues and organs, and allows for more oxygen to make its way to the brain—great for brain health and function. Exercise has also been found to stimulate the formation of new neuronal connections responsible for learning and quick thinking.
Another unexpected benefit of exercise is an immediate antidepressant-like effect following exercise. The hormones responsible were also linked with an increase in the size of an area of the brain that is associated with learning and memory called the cell growth, particularly in the hippocampus.
For the best overall health benefit the Department of Health and Human Services recommends at least 150 minutes a week of moderate aerobic activity (like brisk walking 20 minutes a day) or 75 minutes a week of vigorous aerobic activity (such as running), preferably spread throughout the week.
One study done by the Department of Exercise Science at the University of Georgia found that even a brief 20 minute session of exercise can immediately increase information processing and memory functions. In addition, research published in the journal of Neurology found that walking about six miles a week may keep your brain sharp as you get older. Researchers from the Alzheimer’s Association International Conference found that a brisk 30-minute daily walk can delay mental aging by five to seven years.
To get the most brain-specific benefit from exercise consider these tips:
Remember to always check with your doctor before starting any new exercise program.
