Even a 10-Minute Walk May Be Good for the Brain

Ten minutes of mild exercise can immediately alter how certain parts of the brain communicate and coordinate with one another and improve memory function.

Ten minutes of mild, almost languorous exercise can immediately alter how certain parts of the brain communicate and coordinate with one another and improve memory function, according to an encouraging new neurological study. The findings suggest that exercise does not need to be prolonged or intense to benefit the brain and that the effects can begin far more quickly than many of us might expect.
We already know that exercise can change our brains and minds. The evidence is extensive and growing.

Multiple studies with mice and rats have found that when the animals run on wheels or treadmills, they develop more new brain cells than if they remain sedentary. Many of the new cells are clustered in the hippocampus, a portion of the brain that is essential for memory creation and storage.

The active animals also perform better on tests of learning and memory.

Equivalent experiments examining brain tissue are not possible in people. But some past studies have shown that people who exercise regularly tend to have a larger, healthier hippocampus than those who do not, especially as they grow older. Even one bout of exercise, research suggests, can help most of us to focus and learn better than if we sit still.

Speaking from personal experience, I have found that a walk is more effective than most of the drugs I have been prescribed for depression/anxiety. My historical tendency, at the onset of a bout of depression, would be to withdraw and become practically immobile: lie on the bed or slouch on a sofa. Drugs have typically made me even more lethargic whereas forcing myself (which can be a real struggle) to get out and just walk has invariably improved my mood and reduced anxieties.

I'm not sure that it is exercise alone, in my case, however because going out and being away from my home environment seems to be beneficial too. Especially walks in natural surroundings like the countryside or the coast.
