Brain Exercise

Often the main reason for keeping fit is the positive mental boost it provides. Recent scientific discoveries may explain why this is a key benefit of exercise. Revolutionary evidence, contradicting common belief, shows that new brain cells are created throughout adulthood. Certain cells – called stem cells – can split into two, thereby increasing the total number of cells in the brain.

It seems that regular cardiovascular exercise can help stimulate the production of these new brain cells. Mice, who ran 5 km on a running wheel every day for several months, had twice as many stem cells compared to mice that took no exercise. It is likely the same effect will apply to humans, providing psychological benefits. These benefits may specifically relate to the area of the brain called the "hippocampus", which is associated with memory and mood. CAT scans show the hippocampus is smaller in size in depressed patients, which is probably due to long term stress, as the stress hormone "cortisol" causes brain cell deterioration. Exercise not only counteracts the negative effects of stress, but probably also helps to increase the size of your hippocampus – helping promote a positive mood.

Therefore, whilst regular cardiovascular exercise may keep your body slim, it will keep your brain fat, making it a smart choice.
