Alcohol & Cognition
What even moderate drinking does to your brain
Even moderate alcohol consumption, like a glass or two of wine a few times a week, has measurable effects on your brain's structure and function. Alcohol disrupts the hippocampus, impairing your ability to form new memories and consolidate what you learned that day. The old idea that moderate drinking is harmless or even beneficial for the brain has been largely overturned by more rigorous recent research.
In real life...
If you choose to drink, be strategic about timing. Avoid alcohol on evenings when you've learned something important or need quality sleep for a demanding next day. Having alcohol-free days each week gives your brain recovery time. And if you're working on building a new skill or habit, keeping your evenings alcohol-free during the learning phase will meaningfully improve your retention.
