Exercise, Alcohol Abuse, and Brain Damage.
Heavy drinking has previously been linked to brain damage. However, preliminary studies indicate that individuals who drink heavily but engage in regular physical activity can maintain the health of their white brain matter. The study’s authors are quick to point out that this finding is not a license to drink as much as you can, provided you exercise. Alcohol abuse can still take a toll on many organs in the body, not just your brain.
