Exercise makes the hippocampus (part of the brain that's vital for memory and emotion) to grow in size. Exercise has been shown to reduce changes in the brain that can cause Alzheimer's disease ( a disorder involving loss of mental functions resulting from brain tissue changes mostly due to old age) and Schizophrenia (a psychiatric diagnosis denoting a persistent, often chronic, mental illness variously affecting behavior, thinking, and emotion).
