New Neurons Would Be Created

It used to be accepted that we were born with a certain amount of neurons and that by the time we became an adult no new neurons would be created. This however, has been proven to be incorrect. Through research on animals it has been discovered that new neurons are continually produced in the brain throughout our entire life. Karen Postal, president of the American Academy of Clinical Neuropsychology says that the only activity that is shown to trigger the birth of these new neurons is vigorous aerobic exercise. “If you are exercising so that you sweat – about 30 to 40 minutes – new brain cells are being born” says Postal. So sweating it out on the treadmill or out in the open is doing your brain a lot of good and helping it stay mentally healthy for years to come.

People Who Run Can Recover From Negative Emotions More Quickly

In a study by Emily Bernstein and Richard McNally it was found that aerobic exercise may help reduce negative emotions. Bernstein is a runner and she said “I notice in myself that I just feel better when I’m active”. She wanted to find out why this was the case and to know exactly the effect that exercise has on us. The study set out to look at the way exercise changes the way people react to their emotions. Participants were told to stretch or jog for 30 minutes and were then were shown a sad movie; the final scene of the 1979 film The Champ. The participants then reported their emotional responses. It was found that those who had run for 30 minutes recovered more quickly from their sad emotional experience than those who had just stretched.

Working Memory Would Be Enhanced

A recent study by Lin Li et al titled: “Acute Aerobic Exercise Increases Cortical Activity during Working Memory: A Functional MRI Study in Female College Students”  looks at the effect of acute aerobic exercise on cognitive function. Their study looked at the effect of a session of acute aerobic exercise on working memory. Fifteen young females participated in the study. There were scanned, after an acute exercise session, using a MRI (magnetic resonance imaging) while they performed a working memory task. It was found that the cortex and the left frontal hemisphere showed signs of improvement of control processes. From these findings the researchers noted that this indicates: “acute exercise could benefit working memory at a macro-neural level.” Thus, the study shows a connection between aerobic exercise and improvement in memory.


Next time you are out for a run know that you are doing yourself a world of good. Not only are you aiding your brain on a neurological level you are also working to improve your emotional health. Your cognitive abilities such as memory will be improved and your outlook on life will probably be more positive. If you don’t already run, then you may want to take out those old running shoes and give them a try.
