Excess Alcohol Will Alter Your Brain Chemistry
You may have heard that drinking alcohol kills brain cells. It turns out that well-known brain “fact” is actually a myth. The reality of what heavy drinking does to your brain is much more complex but scary nonetheless. The most dangerous impact that alcohol has on the brain is altering brain chemistry. Even a single drink can change the chemicals that brain cells use to communicate enough to affect your judgment, memory, speech, coordination, and mood. Heavy or binge drinking can severely impair your cognition and memory. It can even slow down your heart rate and the amount of blood and oxygen that reach your brain, which can be life-threatening. One U.K. study found that even moderate drinkers have less grey matter, the outer part of the brain that processes information as it enters the brain.
