Aerobic Exercise Grows Brain Cells, Increases Brain Mass

[This post expands on a link from my July 3 post.]

It was once thought that the brain does not generate new brain cells and once a neuron was gone, it was gone forever. This is what I, like many, was told as a kid. As it turns out, recent science shows that not only do humans continue to generate new brain cells throughout life, aerobic exercise fosters a higher rate of neurogenesis, or the birth of neurons.

Scientists say that, in addition to brain degeneration from aging being curbed by increased neurogenesis, the degeneration can be reversed. Evidence suggests that risks for neurodegenerative problems like Alzheimer’s and Parkinson’s can be curbed and symptoms alleviated. Additionally, scientists are noticing brain degeneration in illnesses like depression and ADHD and problems like anxiety and stress and say that these ailments can be fought with neurogenesis.

The science is still young and this is not a miracle cure-all. But it’s clear that aerobic exercise grows more brain cells and has an impact on everything from depression to the likelihood one will develop Alzheimer’s. I’ve liked to three articles with excerpts below the flip. Feed your brain and learn about neurogenesis
