CAN EXERCISE HELP YOUR BRAIN GROW?

Great news for people who exercise! Exercises can help generate new neurons within your brain! It has historically been believed that you are born with a certain number of neurons and they basically decrease in number as you age. The Salk Institute for Biological Studies have discovered that this is not the case. Exercise can actually stimulate the growth of new neurons. The study included monitoring people who walked for three hours per week for only three months.
The area of the brain that showed the significant amount of growth was the hippocampus, which is the area that’s involved with cognition and memory. In the study, after only three months, the group that exercised had brain volumes typical of those three years younger.
The authors concluded, “These results suggest that cardiovascular fitness is associated with the sparing of brain tissue in aging humans. Furthermore, these results suggest a strong biological basis for the role of aerobic fitness in maintaining and enhancing central nervous system health and cognitive functioning in older adults.” According to the study’s senior author, Dr. Arthur Kramer, “It’s not just a matter of slowing down the aging process. It’s a matter of reversing it.”
